With the development of vehicle intellectualization, the operation of the central control equipment gradually progresses from physical key operation to touch operation, and the size of a central control screen of the central control equipment is also larger and larger. There are also more applications in the central control device that are available for installation by the user.

Currently, applications installed on a central control device may include: driving assistance applications, vehicle control applications, and life entertainment applications. The driving assistance applications described above may be used to provide navigation functions, vehicle position display functions, reverse images, and the like. The above-described vehicle control type application may be used to provide an air conditioner setting function, a door control function, a window control function, a driving mode switching function, and the like. The above-described life entertainment applications may be used to provide music play functions, video play functions, game functions, telephone functions, and the like.

However, the vehicle requires the driver to concentrate on driving the vehicle during driving. The more complex the road conditions, the higher the demand for driver attention. The wide variety of applications on the central control device can attract the attention of users, increase the response time of drivers to emergency events and bring potential safety hazards to vehicle driving.

Disclosure of Invention

The application control method and the related device for the vehicle central control equipment are provided. The method can adjust the number of application icons displayed on the central control screen and the number of running applications in the central control equipment according to the change of the driving information of the vehicle. The method can dynamically adjust the distraction degree of the application on the central control equipment to the driver, so that the driver can pay enough attention to the driving of the vehicle, and the driving safety is improved.

In a first aspect, the present application provides an application control method of a vehicle central control device. The central control device can acquire first driving information of the vehicle in a first time period and determine a first display mode according to the first driving information. The central control device can display the application in the central control device according to a first display mode. The central control device may acquire second driving information of the vehicle in a second time period, and determine a second display mode according to the second driving information, where the second time period is a period of time after the first time period, the first driving information is different from the second driving information, and the first display mode is different from the second display mode. The central control device may display the application in the central control device in a second display mode.

According to the method, the central control device can adjust the display mode of the application on the central control screen according to the change of the driving information, and the situation that the attention of a driver is excessively dispersed on the application of the central control device is avoided, so that the driving safety is improved.

In combination with the first aspect, in some embodiments, the first driving information is changed to the second driving information in a first direction, the first direction being for indicating a direction in which an attention demand for driving of the vehicle increases.

With reference to the first aspect, in some embodiments, the first direction includes one or more of: the direction in which the vehicle speed increases, the direction in which the level of the automatic driving mode decreases, the direction in which the congestion degree of the road increases, the direction in which the number of pedestrians on the road increases, the direction in which the number of vehicles on the road increases, and the direction in which the degree of straightness of the road increases.

In combination with the first aspect, in some embodiments, in a case where the first driving information is changed to the second driving information in the first direction, the distinction between the first display manner and the second display manner includes: the number of application icons displayed by the central control device according to the second display mode is smaller than the number of application icons displayed according to the first display mode, and/or the distraction degree of the application corresponding to the application icons displayed by the central control device according to the second display mode in the first area is smaller than the distraction degree of the application corresponding to the application icons displayed by the central control device according to the first display mode in the first area, wherein the first area is an area, close to a driving position, on a screen of the central control device.

As can be seen from the above embodiments, the central control device can reduce the number of application icons displayed on the central control screen and/or adjust the display positions of the application icons on the central control screen when the driver is required to pay more attention to driving of the vehicle after the driving information is changed.

The central control device can hide application icons of the application with high distraction degree. This can reduce the chance that the driver operates an application that is easily distracted during driving, thereby avoiding that the driver is distracted by the application on the operation center screen, affecting driving safety.

Optionally, the central control device may further display an application icon of an application with a small distraction degree on the central control screen near an area where the driving position is located, and display an application icon of an application with a large distraction degree on the central control screen where the drivability driving position is located. This can facilitate the driver to quickly operate the icon of the application with a small degree of distraction. Moreover, application icons of the applications with high distraction degree are displayed in the area far away from the driving position on the central control screen, so that the influence of the applications on the attention of a driver can be better reduced, and the driving safety is improved.

In combination with the first aspect, in some embodiments, the case where the central control device adjusts the display position of the application icon according to the change of the driving information may include: the icon of the first application displayed in the first area by the central control device moves to the second area, wherein the second area is an area far away from the driving position on the screen of the central control device, and/or the icon of the second application displayed in the second area by the central control device moves to the first area by the first display mode, and the distraction degree of the first application to the attention is larger than that of the second application.

Wherein the first application may include one or more applications. The second application may also include one or more applications. The first application is more distracted than the second application.

It can be seen that, when the driver is required to pay more attention to driving the vehicle after the driving information is changed, the central control apparatus may move the application icons for adjusting the display positions of the application icons, more applications with less distraction to the driver's position (i.e., a region where the driver is more likely to operate), and more application icons for applications with greater distraction to the driver's position to a region away from the driving position.

In combination with the first aspect, in some embodiments, the central control device may run the third application before the central control device obtains the second driving information of the vehicle within the second period of time. After the central control device obtains the second driving information of the vehicle in the second time period, the central control device may stop running the third application.

The third application may be an application that needs to stop running, which is determined by the central control device according to the second driving information.

As can be seen from the above embodiments, the central control apparatus may also adjust the number of applications running in the central control apparatus according to the change of the driving information. It will be appreciated that the application may create visual, non-visual, appeal to the driver during operation. And the driver's operation of the running application is also distracting. After the driving information is changed, the central control device can stop running the application which is running by more central control devices under the condition that the driver needs to pay more attention to the driving of the vehicle.

The method can reduce the excessive application of the central control equipment to attract the attention of the driver, so that the driver can pay enough attention to the driving of the vehicle, and the driving safety is improved.

The stopping of the third application may mean closing the third application, and ending the process of the third application in the background of the central control device. Alternatively, stopping running the third application may mean suspending running the third application, and retaining a process of the third application in the background of the central control device.

In combination with the first aspect, in some embodiments, after the central control device obtains the second driving information of the vehicle in the second period of time, the central control device further receives a first operation to start the fourth application. In response to the first operation, the center control device may refuse to start the fourth application according to the second driving information.

As can be seen from the above embodiments, when the central control device receives an operation of starting an application, it may also determine whether to start the application according to current driving information. In this case, if the application to be started by the above operation is excessively distracted after the start, the center control device may refuse to start the application in a case where it is difficult for the driver to pay sufficient attention to the driving of the vehicle. The method can avoid the situation that a driver starts an application with higher distraction degree in the operation stage in the driving process of the vehicle, so that the driver can pay enough attention to the driving of the vehicle, and the driving safety is improved.

In combination with the first aspect, in some embodiments, a fifth application is running in the central control device, and a first interface of the fifth application is displayed on a screen of the central control device, where the first interface includes a plurality of controls, and the plurality of controls are used to call a plurality of functions of the fifth application. After the central control device obtains the first driving information of the vehicle in the first time period, the central control device can further determine a third display mode according to the first driving information, and display one or more of the plurality of controls on the first interface according to the third display mode. After the central control device obtains the second driving information of the vehicle in the second time period, the central control device can further determine a fourth display mode according to the second driving information, and display one or more of the plurality of controls on the first interface according to the fourth display mode, wherein the third display mode is different from the fourth display mode.

According to the embodiment, the central control device can adjust the display mode of the user interface of the application according to the change of the driving information, so that excessive distraction of a driver due to the operation of one or more functional controls in the application interface is avoided, and the driving safety is improved.

With reference to the first aspect, in some embodiments, the distinguishing between the third display mode and the fourth display mode includes: the number of the controls displayed by the central control device according to the fourth display mode is smaller than the number of the controls displayed according to the first display mode.

It can be seen that the central control device can reduce the number of controls on the first interface of the fifth application in case the driver is required to pay more attention to the driving of the vehicle after the driving information is changed. The function corresponding to the hidden control may be a function with a large degree of distraction. The control device can reduce the chance that a driver operates the control corresponding to the function which is easy to be distracted in the driving process, so that the driver is prevented from being distracted due to the application on the operation center control screen, and the driving safety is prevented from being influenced.

In the above embodiment, the central control device may hide each function provided by one application alone. Hiding one function in an application may not affect the use of other functions in the application. The driver can continue to use other functions in an application that are not hidden. This may reduce the impact of hiding an application on the driver's use of the application, on the basis of enabling to avoid that the driver is excessively distracted by using the application on the central control device.

In some embodiments, the central control device may further adjust a display position of each control in the first interface of the fifth application according to a change of the driving information. For example, the central control device may display a control corresponding to a function with a small distraction degree in an area of the first interface near the driving position, and display a control corresponding to a function with a large distraction degree in an area of the first interface far from the driving position.

In combination with the first aspect, in some embodiments, the functions of the fifth application include a first function, and before the central control device obtains the second driving information of the vehicle in the second period of time, the central control device may run a program corresponding to the first function. After the central control device obtains the second driving information of the vehicle in the second time period, the central control device can stop running the program corresponding to the first function.

The program corresponding to the first function may be a program that the central control device determines that the operation needs to be stopped according to the second driving information.

As can be seen from the above embodiments, the central control device may also adjust part of the functions in the running application in the central control device according to the change of the driving information. It will be appreciated that the degree of distraction to the driver of the different functions provided by the application may be different. After the driving information is changed, in the case where the driver is required to pay more attention to the driving of the vehicle, the center control device may stop running the program of a part of the functions (such as the functions having a high degree of distraction) in the application, and continue running the program of another part of the functions (such as the functions having a low degree of distraction) in the application. This may reduce the impact of hiding an application on the driver's use of the application, on the basis of enabling to avoid that the driver is excessively distracted by using the application on the central control device.

With reference to the first aspect, in some embodiments, the functions of the fifth application include a second function, and after the central control device acquires second driving information of the vehicle in a second period of time, the central control device receives a second operation of calling the second function; in response to the second operation, the center control device may refuse to activate the second function according to the second driving information.

As can be seen from the above embodiments, when the central control device receives an operation of calling a function in the application, it may also determine whether to start the function according to current driving information. If the function to be invoked by the above operation is excessively distracted after being started, the central control device may refuse to start the function in a case where the driver is difficult to pay sufficient attention to driving the vehicle. The method can avoid the situation that the driver starts the function with higher distraction degree in the operation stage in the driving process of the vehicle, so that the driver can pay enough attention to the driving of the vehicle, and the driving safety is improved.

In combination with the first aspect, in some embodiments, the central control device may acquire third driving information of the vehicle in a third period of time, and determine a fifth display manner according to the third driving information, where the third period of time is a period of time after the second period of time, and the fifth display manner is different from the second display manner, where the second driving information is changed to the third driving information in a second direction, and the second direction is used for indicating a direction in which a demand for attention of driving of the vehicle is reduced. The central control device may display the application in the central control device according to the fifth display mode.

With reference to the first aspect, in some embodiments, the second direction includes one or more of: the direction in which the vehicle speed decreases, the direction in which the level of the automatic driving mode rises, the direction in which the congestion degree of the road decreases, the direction in which the number of pedestrians on the road decreases, the direction in which the number of vehicles on the road decreases, and the direction in which the degree of straightness of the road decreases.

With reference to the first aspect, in some embodiments, the distinction between the fifth display mode and the second display mode includes: the number of application icons displayed by the central control device according to the fifth display mode is greater than the number of application icons displayed according to the second display mode, and/or the distraction degree of the application corresponding to the application icons displayed by the central control device according to the second display mode in the first area is smaller than the distraction degree of the application corresponding to the application icons displayed according to the fifth display mode in the first area, and the first area is an area, close to the driving position, on the screen of the central control device.

As can be seen from the above embodiments, in the event of a change in driving information, the driver may pay less attention to the driving of the vehicle and the central control device may resume displaying one or more previously hidden application icons. That is, the display mode of the application on the central control screen can be dynamically adjusted according to the change of the driving information. If the driver needs to pay more attention to the driving of the vehicle under the current driving information, the display mode of the application on the central control screen can reduce the chance that the driver operates the application which is easy to be distracted in the driving process. If the driver can pay less attention to the driving of the vehicle under the current driving information, the display mode of the application on the central control screen can increase more application icons with more distraction degree, so that the driver can use more applications. The method not only can reduce the situation that the attention of the driver is excessively dispersed by the application on the central control equipment, but also can reduce the influence of the application in the use of the central control equipment by the driver.

In combination with the first aspect, in some embodiments, the third application is stopped after the central control device acquires the second driving information, and after the central control device acquires the third driving information of the vehicle in the third period of time, the central control device may resume running the third application.

As can be seen from the above embodiments, in the case where the driving information is changed, the driver can pay less attention to the driving of the vehicle, and the center control device can resume the application that was stopped before the operation.

For example, the center control device stops running the music application according to the second driving information. Then the playing music in the music application pauses the playing. When the third driving information is acquired, the central control device can resume running the music application according to the third driving information. Then the music played in the music application may start playing from the last pause position.

In combination with the first aspect, in some embodiments, before the central control device determines the second display mode according to the second driving information, the central control device may further detect that a user exists in a co-driving position of the vehicle. The center control device may acquire fourth driving information of the vehicle in a fourth period of time, and detect that there is no user at the co-driving position of the vehicle in the fourth period of time, the fourth period of time being a period of time after the second period of time, the fourth driving information being the same as the second driving information. The central control device may determine a sixth display mode according to the fourth driving information, and display the application in the central control device according to the sixth display mode.

The difference between the sixth display mode and the second display mode includes: the number of application icons displayed by the central control device according to the sixth display mode is smaller than the number of application icons displayed according to the second display mode, and/or the distraction degree of the application corresponding to the application icons displayed by the central control device according to the sixth display mode in the first area is smaller than the distraction degree of the application corresponding to the application icons displayed according to the second display mode in the first area, and the first area is an area, close to the driving position, on the screen of the central control device.

As is apparent from the above-described embodiments, when the driving information is the same, the display manner of the center control device display application in the case where there is only the driver in the front row in the vehicle is different from the display manner of the center control device display application in the case where there are both the driver and the co-driver in the front row in the vehicle. It will be appreciated that the vehicle may be driven without the need for the co-driver to pay attention to. The number of applications that the center control device hides in the case where there is both the driver and the co-driver in the front row in the vehicle may be smaller than in the case where the vehicle is in the same running state but there is only the driver in the front row in the vehicle. This can reduce the influence of adjusting the display mode of the application according to the driving information on the application in the secondary driver's use of the center control device.

With reference to the first aspect, in some embodiments, a specific method for determining, by the central control device, the first display manner according to the first driving information may be: the central control device may determine the attention demand level ARL as the first ARL according to the first driving information, and acquire the distraction level ADL applied in the central control device. And the central control equipment determines a first display mode according to the first ARL and the ADL applied in the central control equipment. The first display mode includes hiding icons of applications with ADL higher than a first ADL threshold corresponding to the first ARL, and/or displaying icons of applications with ADL smaller than or equal to the first ADL threshold in a first area, wherein the first area is an area, close to a driving position, on a screen of the central control device.

The specific method for the central control device to determine the second display mode according to the second driving information may be: the center control device may determine the attention demand level ARL as the second ARL based on the second driving information. And the central control equipment determines a second display mode according to the second ARL and the ADL applied in the central control equipment. The second display mode includes hiding icons of applications with ADL higher than a second ADL threshold corresponding to the second ARL, and/or displaying icons of applications with ADL smaller than or equal to the second ADL threshold in the first area.

With reference to the first aspect, in some embodiments, the second ARL is greater than the first ARL, and a second ADL threshold corresponding to the second ARL is less than a first ADL threshold corresponding to the first ARL.

The larger the ARL, the more attention the driver needs to pay to drive the vehicle. The second ARL being larger than the first ARL may indicate that the first driving information is changed to the second driving information in the first direction (i.e., in a direction in which the attention demand for driving the vehicle increases).

The larger the ARL, the greater the ADL threshold to which the ARL corresponds. Thus, as the ARL increases, the center control device may hide more applications of smaller ADLs, thereby reducing the distraction of the applications in the center control device so that the driver can put sufficient attention on the vehicle driving.

With reference to the first aspect, in some embodiments, the ADL of the application is an ADL of the application in a startup phase. The central control equipment evaluates the ADL of the application in the starting stage according to the application starting information, wherein the application starting information comprises: the operation complexity and the application category of the application are started, wherein the higher the operation complexity of the application is, the higher the ADL of the application is in the starting stage; under the condition that the operation complexity is the same when the application is started, the ADL of the application with the application category being the driving assistance category in the starting stage is smaller than the ADL of the application with the application category being the non-driving assistance category in the starting stage.

In combination with the first aspect, in some embodiments, after the central control device determines, according to the first driving information, that the attention requirement level ARL is the first ARL, the central control device may acquire an ADL of an application running in the central control device in a running phase. The central control device hides applications where the ADL of the application at run-time is above a first ADL threshold. After the central control device determines that the attention requirement level ARL is the second ARL according to the second driving information, the central control device may acquire the ADL of the running application in the central control device in the running stage. The central control device hides applications where the ADL of the application in the run phase is above a second ADL threshold.

With reference to the first aspect, in some embodiments, the central control device may evaluate an ADL of an application in an operation phase according to application operation information, where the application operation information includes: the method comprises the steps of operating complexity of an application in an operation stage when the application needs user operation, duration of visual attraction or duration of non-visual attraction when the application does not need user operation in the operation stage, and application category, wherein the greater the operating complexity of the application in the operation stage when the application needs user operation, the greater the ADL of the application in the operation stage; the longer the duration of visual attraction or the duration of non-visual attraction when the application does not need user operation in the operation stage, the larger the ADL of the application in the operation stage; when the application requires user operation in the operation stage, the operation complexity is the same, or the duration of visual attraction is the same or the duration of non-visual attraction is the same when the application does not require user operation in the operation stage, the ADL of the application with the application class of driving assistance class in the operation stage is smaller than the ADL of the application with the application class of non-driving assistance class in the operation stage.

In combination with the first aspect, in some embodiments, the central control apparatus may acquire third driving information of the vehicle in a third period of time, and determine a third ARL according to the third driving information. The third period of time may be a period of time after the second period of time. The third ARL is less than the second ARL described above. The central control device may hide, according to the third ARL, an application icon of an application whose ADL in the start-up phase is higher than a third ADL threshold corresponding to the third ARL, and display an application icon of an application whose ADL in the start-up phase is less than or equal to the third ADL threshold. That is, the center control device may resume displaying the application icon hidden according to the second driving information. And the application corresponding to the application icon which is restored to be displayed is the application of which the ADL in the starting stage is higher than a second ADL threshold corresponding to the second ARL and smaller than or equal to a third ADL threshold corresponding to the third ARL.

Optionally, the central control device may further stop running the application with the ADL in the running stage higher than the third ADL threshold according to the third ARL, and keep the ADL in the running stage smaller than or equal to the third ADL threshold. The central control device may resume running the application that is stopped according to the second driving information. The application which is restored to be operated is the application of which the ADL in the operation stage is higher than the second ADL threshold and smaller than or equal to the third ADL threshold.

In combination with the first aspect, in some embodiments, a correspondence between driving information and a display manner may be stored in the central control device. When the first driving information is obtained, the central control device can inquire that the display mode of the application corresponding to the first driving information is the first display mode. Optionally, when the first driving information is obtained, the central control device may further view a display manner of a user interface of an application corresponding to the first driving information.

According to the embodiment, the central control device can determine the current display mode of the application or the display mode of the user interface of the application on the central control screen according to the corresponding relation between the driving information and the display mode. Thus, the central control device does not need to evaluate the ARL according to the driving information and then determine the display mode according to the ARL and the ADL. The embodiment can improve the efficiency of the central control equipment in adjusting the display mode, and more rapidly adjust the attraction of the central control equipment to the attention of the driver according to the change of the driving information, thereby improving the driving safety.

In a second aspect, the present application provides an electronic device, which may comprise a screen, a memory, one or more processors, wherein the screen may be used to display application icons, a user interface of an application, the memory may be used to store a computer program, and the one or more processors may be used to invoke the computer program, such that the electronic device performs any of the possible implementation methods as in the first aspect.

In a third aspect, the present application provides a computer readable storage medium comprising instructions which, when run on an electronic device, cause the electronic device to perform any one of the possible implementation methods as in the first aspect.

In a fourth aspect, the present application provides a computer program product which may contain computer instructions which, when run on an electronic device, cause the electronic device to perform any one of the possible implementations of the first aspect.

In a fifth aspect, the present application provides a chip for application to an electronic device, the chip comprising one or more processors for invoking computer instructions to cause the electronic device to perform any of the possible implementations of the first aspect.

It will be appreciated that the electronic device provided in the second aspect, the computer readable storage medium provided in the third aspect, the computer program product provided in the fourth aspect, and the chip provided in the fifth aspect are all configured to perform the method provided by the embodiments of the present application. Therefore, the advantages achieved by the method can be referred to as the advantages of the corresponding method, and will not be described herein.

Detailed Description

The technical solutions in the embodiments of the present application are described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments of the present application, the terminology used in the embodiments below is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of this application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include, for example, "one or more" such forms of expression, unless the context clearly indicates to the contrary. It should also be understood that in the various embodiments herein below, "at least one", "one or more" means one or more than two (including two). The term "and/or" is used to describe an association relationship of associated objects, meaning that there may be three relationships; for example, a and/or B may represent: a alone, a and B together, and B alone, wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise. The term "coupled" includes both direct and indirect connections, unless stated otherwise. The terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The term "User Interface (UI)" in the following embodiments of the present application is a media interface for interaction and information exchange between an Application (APP) or an Operating System (OS) and a user, which implements conversion between an internal form of information and a form acceptable to the user. The user interface is a source code written in a specific computer language such as java, extensible markup language (extensible markup language, XML) and the like, and the interface source code is analyzed and rendered on the electronic equipment to finally be presented as content which can be identified by a user. A commonly used presentation form of the user interface is a graphical user interface (graphic user interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be a visual interface element of text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc., displayed in a display of the electronic device.

In some embodiments, the vehicle may reduce the probability of a traffic accident due to a driver making a mistake through driving assistance techniques. For example, an automatic emergency braking device may be mounted on the vehicle. When the vehicle encounters an emergency dangerous situation or the distance between the vehicle and the front vehicle and the pedestrian is smaller than the safety distance, the vehicle can be actively braked through the automatic emergency braking device. For another example, a lane assist system may be disposed on the vehicle to ensure that the vehicle travels in a lane to avoid the vehicle occupying multiple lanes while traveling or suddenly traveling out of the travel path toward another lane. As another example, a driver monitoring system may be configured on the vehicle. When the driver's achievement is monitored to move away from the front road for a period of time, the vehicle may prompt or alert to prompt the user to increase the attention of the driver.

The above method can reduce to some extent the probability of driving accidents due to driver distraction (e.g. distraction by an application on the central control device). However, the above method has difficulty in avoiding the influence of the application on the center control device on the distraction of the driver. When a driver is required to be highly focused on driving, the application on the central control device disperses the driver's attention, which is liable to cause driving accidents.

The application control method of the vehicle central control equipment can adjust the influence degree of the application on the central control equipment on the distraction of the driver according to the attention requirement of the driver in the driving process, so that the driver can pay enough attention to the driving of the vehicle to cope with the current driving road condition, and the driving safety is improved.

Specifically, the central control device may make an attention demand ranking (attention requirement level, ARL) assessment based on the driving information. The ARL may represent the level of attention required by the driver to drive the vehicle. The higher the ARL, the higher the driver's attention is required for vehicle driving. The driving information may include a driving state of the vehicle, a road condition (e.g., a degree of curve of the road, the number of pedestrians on the road, the number of vehicles on the road, a degree of congestion of the road), and the like. The central control device may also evaluate the level of distraction (attention distraction level, ADL) of the application on the central control device during the start-up phase and the run phase. The ADL of the application in the start-up phase may indicate how much the application is distracted to the driver. The ADL of the application at the run-time may indicate how much the application is distracted from the driver during the run-time. The higher the ADL, the more distracted the application is to the driver. The central control device can hide part of application icons displayed on the central control screen according to the ARL, the ADL applied in the starting stage and a preset application hiding strategy, so that the driver is prevented from being distracted by manually starting the application with the hidden application icons. The central control device can close the part of the applications running in the central control device according to the ARL, the ADL of the applications in the running stage and the preset application hiding strategy, so that the running of the closed applications is prevented from being distracted by a driver. The application hiding policy described above may be used to indicate the size of the ADL for applications that need to be hidden under different ARLs.

According to the method, the central control device can adjust the number of application icons displayed on the central control screen and the number of applications running in the central control device according to the change of the driving information. The central control device can hide the application of excessive distraction to the current driving according to the requirement on the attention of the driver in the driving process. The hiding of the application by the central control device can include hiding an application icon displayed on the central control screen and/or refusing to run the application. The method can reduce the situation that the driver operates the application which is easy to be distracted in the driving process, thereby avoiding the excessive distraction of the driver on the application of the central control equipment and improving the driving safety.

In some embodiments, an application control table may be stored in the central control device. The application control table described above may be used to indicate the relationship between different driving information and applications that need to be hidden. The central control device can judge which applications are applications needing to be hidden currently according to the driving information acquired currently and the application control table. Then, when the driving information changes, the center control device may adjust the hidden application in the center control device.

In one possible implementation manner, when determining the application to be hidden according to the driving information currently acquired and the application control table, the central control device may hide the icon of the application to be hidden on the central control screen, and stop running the running application in the application to be hidden.

In another possible implementation manner, the application control table may specifically include applications that need to be hidden corresponding to different driving information, and a manner of hiding the applications. The above manner of hiding the application may include: hiding the referenced icon on the central control screen and refusing to run the application. When determining the application to be hidden according to the currently acquired driving information and the application control table, the central control device can hide the application to be hidden according to the corresponding application hiding mode in the application control table.

The relation between the driving information and the application to be hidden may also be stored in the center control device by other means, not limited to the application control table.

For example, the driving information may include a vehicle speed. In the above application control table, the faster the vehicle speed, the more applications that need to be hidden. The application control table may contain identifications of applications that need to be hidden at different vehicle speeds. If the application to be hidden when the vehicle speed is v1 comprises applications a1 to an application an, the central control equipment hides the applications a1 to the application an when detecting that the current vehicle speed is v 1. Hiding the application a1 to the application an may include hiding icons of the application a1 to the application an on the central control screen and stopping running the running application of the application 1 to the application an. Optionally, the application control table further includes a manner of hiding the application under different driving information. The central control device may determine, according to the application control table, a manner of hiding the applications a1 to an when the number v1 of vehicles is set. For example, the ways to hide the applications a1 to an include: and hiding icons of partial applications (such as the applications a1 to aq) in the applications a1 to an on the central control screen, and stopping running the partial applications (such as the applications a1 to am) in the applications a1 to an. The central control device can hide the icons of the applications a1 to aq on the central control screen according to the hiding mode, and stop running the running application in the applications a1 to am. It will be appreciated that the central control device may display an icon of an application (i.e., other applications than the application a 1-application an described above) for which the application control table does not declare a need to be hidden at the vehicle speed v1, and may run the application for which the need to be hidden is not declared.

For another example, the driving information may include a hierarchy of automatic driving modes. In the above application control table, the higher the level of the automatic driving mode, the fewer applications that need to be hidden. The application control table may contain the identity of applications that need to be hidden at the level of different autopilot modes. If the application to be hidden when the level of the automatic driving mode is L3 comprises the applications b1 to bn, the central control equipment hides the applications b1 to bn when detecting that the level of the automatic driving mode is L3. The method for hiding the application by the central control device can refer to the description of the foregoing embodiment. It will be appreciated that applications other than the application b 1-application bn described above may not be hidden.

As another example, the driving information may include a congestion degree of the road. In the application control table, the higher the congestion degree of the road is, the more applications need to be hidden. The application control table may contain identifications of applications that need to be hidden under different levels of congestion on the road. The congestion degree of the road may include different levels: smooth, comparatively congested and particularly congested. The present application does not limit the way of grading the congestion level of the road. If the application to be hidden when the road is particularly congested includes applications c1 to cn, the central control device hides the applications c1 to cn when the road is particularly congested. The method for hiding the application by the central control device can refer to the description of the foregoing embodiment. It will be appreciated that other applications than the above application c1 to application cn may not be hidden.

The driving information may further include more content, which is not limited in this embodiment of the present application.

The application control table may include a relationship between a single item of driving information and an application to be hidden under different values, and may also include a relationship between multiple items of driving information and an application to be hidden under different values when the multiple items of driving information are combined. For example, the application control table may include an identification of an application that needs to be hidden at different vehicle speeds. The hidden application table may further include an identifier of an application that needs to be hidden when the vehicle speed is at the specified vehicle speed and the level of the automatic driving mode is at the specified level.

According to the embodiment, the central control device can quickly determine the application needing to be hidden according to the driving information and the application control table. Thus, the central control device can determine the application needing to be hidden according to the ARL and the ADL without evaluating the ARL according to the driving information. The embodiment can improve the efficiency of hiding the application by the central control equipment, and more rapidly adjust the attraction of the application to the attention of the driver in the central control equipment according to the change of the driving information, thereby improving the driving safety.

In some embodiments, the central control device may update the application control table described above. For example, the central control device installs a new application, and the central control device may add an identification of the application to the application control table. In this way, the central control device can determine whether to hide the application during the running process of the vehicle. In one possible implementation manner, the central control device may obtain the application control table from the cloud server. The cloud server can store driving information values corresponding to all applications in the application market when the applications need to be hidden. The central control equipment installs a new application, and can acquire the corresponding driving information value when the application needs to be hidden from the cloud server, so that the application control table is updated. In another possible implementation manner, the central control device may obtain the application control table according to the ADL of the application. The central control device installs a new application and can determine the ADL of the application. And then, the central control equipment can determine the corresponding driving information value when the application needs to be hidden according to the ADL of the application, so that the application control table is updated.

An implementation method for evaluating an ARL provided in the embodiments of the present application is described below.

The requirements of the vehicle for the attention of the driver during the driving process are different according to the running state of the vehicle, the driving mode, the road condition and other factors.

For example, in the case where the vehicle is stopped, the demand for attention of the driver is close to 0. I.e. the driver may not need to pay attention to the driving of the vehicle while the vehicle is stopped.

As another example, the faster the vehicle speed, the higher the demand for driver attention during vehicle travel. The more complex the road conditions during the running of the vehicle (such as a meandering running road, a lot of vehicles and pedestrians on the road), the higher the attention requirements of the driver.

For another example, the higher the level of the automatic driving mode in the automatic driving mode, the fewer cases where the user is required to manually operate the vehicle to drive. Then the higher the level of the automatic driving mode, the lower the demand for driver attention.

In one possible implementation, the central control device may collect driving information of the vehicle and evaluate the ARL of the vehicle driving based on the driving information. The driving information may include a driving state of the vehicle and a road condition. The vehicle driving status may include a vehicle speed, whether the automatic driving mode is turned on, a hierarchy of the automatic driving mode. Road conditions may include the degree of curve of the road, the number of pedestrians on the road, the number of vehicles on the road, the degree of congestion of the road.

Wherein, according to the difference of the attention requirements of the driver in the running process of the vehicle, the ARL can be divided into six grades: ARL0, ARL1, ARL2, ARL3, ARL4, ARL5.

ARL0 may indicate that the vehicle may be traveling without the driver being attentive to driving. In the case where ARL is ARL0, the driver is generally not required to perform any driving operation.

ARL1 may indicate that driving of the vehicle requires at least a small amount of attention from the driver in driving. In the case where ARL is ARL1, the driver is usually required to perform only a small amount of driving operation, and the driver may be mostly attentive not to driving. For example, in the automatic driving mode, the driver may only need to answer or take over driving when requested by the system.

ARL2 may indicate that driving of the vehicle requires at least a driver to pay a major amount of attention to driving. For example, in the automatic driving mode, if the driver is ready to take over driving actively at any time, the center control device may evaluate to determine ARL as ARL2.

ARL3 may represent that driving of the vehicle requires the driver to pay a large part of his attention to driving.

ARL4 may indicate that the vehicle is traveling requiring the driver to pay a great deal of attention to driving to ensure timely handling of various conditions during vehicle travel (e.g., parking in time when a red light is encountered or pedestrians are in front, paying attention to the coming vehicles behind when a lane change is made, etc.). In the case of ARL4, most of the driving operations during the running of the vehicle need to be manually completed by the driver.

ARL5 may indicate that the vehicle is traveling requiring driver distraction and focus on vehicle driving to ensure rapid response to various conditions during vehicle travel.

The division of ARL into the above six classes ARL0 to ARL5 is merely illustrative, and should not be construed as limiting the present application. The ARL may also be classified into more or less levels depending on the attention requirements of the driver during the travel of the vehicle.

The central control device may evaluate which level the current ARL is based on the currently collected driving information.

The central control apparatus will be described below as a case where the ARL includes six grades ARL0 to ARL5.

(1) When it is detected that the vehicle is stopped (i.e., the vehicle speed is 0), the center control device may determine that the current ARL is ARL0.

(2) When the vehicle is in the manual driving mode, the central control device can determine that the current ARL is ARL3 when the vehicle is detected to run at a low speed and the road condition is simple.

(3) When the vehicle is in the manual driving mode and the vehicle is detected to run at a medium speed or the road condition is complex, the central control equipment can determine that the current ARL is ARL4.

(4) When the vehicle is in the manual driving mode and the vehicle is detected to run at a high speed or the road condition is complex, the central control device can determine that the current ARL is ARL5.

The low-speed travel of the vehicle may be, for example, a travel speed of the vehicle of less than 40 km/h. The vehicle medium speed running may be, for example, a running speed of the vehicle greater than or equal to 40 km/h and less than or equal to 60 km/h. The high-speed running of the vehicle may be, for example, a running speed of the vehicle greater than 60 km/h. The above-described division of the low-speed running, the medium-speed running, and the high-speed running of the vehicle according to the running speed is merely an exemplary illustration, and should not be construed as limiting the present application. The center control device may also divide the low-speed running, the medium-speed running, and the high-speed running according to other dividing means.

The central control device can judge whether the road condition is simple, complex or complex according to the curve degree of the vehicle driving road, the number of pedestrians on the road, the number of vehicles on the road and the like. For example, when it is detected that the degree of curve of the road is in the first curve section, the number of pedestrians on the road is in the first pedestrian number section, and the number of vehicles on the road is in the first vehicle number section, the center control device may determine that the road condition is simple. When the curve degree of the road is detected to be in the second curve section, or the number of pedestrians on the road is detected to be in the second pedestrian number section, or the number of vehicles on the road is detected to be in the second vehicle number section, the central control device can determine that the road condition is complex. When the curve degree of the road is detected to be in a third curve section, or the number of pedestrians on the road is detected to be in a third pedestrian number section, or the number of vehicles on the road is detected to be in a third vehicle number section, the central control device can determine that the road condition is complex. The value in the first curved section is smaller than the value in the second curved section. The value of the second curved section is smaller than the value of the third section. The value of the first pedestrian number zone is smaller than the value of the second pedestrian number zone. The value of the second pedestrian number section is smaller than the value of the third pedestrian number section. The value of the first vehicle number zone is smaller than the value of the second vehicle number zone. The value of the second vehicle number interval is smaller than the value of the third vehicle number interval. The above-mentioned central control device determines whether the road condition is simple or complex, or the complex mode is merely an exemplary illustration, and should not be limited to this application.

(5) When the level of the detected automatic driving mode is L0 to L2 in the automatic driving mode of the vehicle, the strategy for evaluating the ARL by the center control device may be the same as the strategy for evaluating the ARL when the vehicle is in the manual driving mode.

(6) When the level of the automatic driving mode is detected as L3 while the vehicle is in the automatic driving mode, the center control device may determine that the current ARL is ARL2.

(7) When the level of the automatic driving mode is detected as L4 while the vehicle is in the automatic driving mode, the center control device may determine that the current ARL is ARL1.

(8) When the level of the automatic driving mode is detected as L5 while the vehicle is in the automatic driving mode, the center control device may determine that the current ARL is ARL0.

The level of the automatic driving mode may be divided into L0 to L5 in the order from low to high. The hierarchy of the above-described autopilot mode is merely an exemplary illustration and should not be construed as limiting the present application. It will be appreciated that the autopilot mode may also include more or fewer levels.

The specific size of the ARL of the vehicle under different driving conditions is only illustrative of the application and should not be construed as limiting the application. The method is not limited to the use of the running state and road condition of the vehicle, and other driving information is adopted for ARL in the running process of the vehicle, so long as the method is based on the same thought provided by the application, and the method is within the protection scope of the application.

The following describes a method for implementing ADL of an evaluation application provided in the embodiments of the present application.

The central control device may contain three categories of applications: driving assistance applications, vehicle control applications, and life entertainment applications. The degree of distraction to the driver varies from application to application. I.e. the ADL for different applications may be different.

Wherein the driving assistance class application is usable for assisting the driver in driving. The driver assistance class application is less distracting to the driver.

Vehicle control class applications generally draw the driver's attention during operation, with the degree of distraction to the driver depending on the ease of operation and the duration of operation. Wherein the more difficult it is to control the operation of the vehicle using a vehicle control class application, the greater the degree of distraction of the vehicle control class application to the driver. The longer the operation time of the vehicle is controlled using the vehicle control class application, the greater the degree of distraction of the vehicle control class application to the driver.

After start-up, life-entertainment applications are typically persistent in their attention to the driver. The distraction of the entertainment applications to the driver is often the greatest among the three categories of applications described above.

In addition, the ADL of the application may include an ADL of the application at a start-up phase, an ADL of the application at a run phase. It will be appreciated that the degree of distraction to the driver during the start-up phase and the run-up phase of an application may also be different. For example, a driver may start a video application in a central control device by voice command without the driver manually operating the central control screen and staring at the central control screen with eyes, the ADL of the video application during the start-up phase is relatively small. The video application will continuously attract the driver's vision during the run-time period, and more distract the driver, the ADL of the video application during the run-time period will be relatively large.

In one possible implementation, the central control device may evaluate the ADL of the application in the startup phase according to the complexity of the operation of the application in the startup phase, the application class. The central control device can evaluate the ADL of the application in the run-time according to whether the application requires user operation in the run-time, complexity of operation, attention to the driver, and application category.

The ADL may be classified into six classes according to the degree of distraction of the application to the driver: ADL0, ADL1, ADL2, ADL3, ADL4, ADL5.

ADL0 may indicate that the application hardly attracts the attention of the driver, or that the operation performed using the application itself belongs to the driving need. In the case where ADL of one application start-up phase or run phase is ADL0, the one application start-up or run will not normally interfere with driver driving. Thus, the driver can pay enough attention to the vehicle driving, so that the emergency can be rapidly processed, and the occurrence of driving accidents is reduced.

ADL1 may indicate that the application will draw a small portion of the driver's attention. In the case where ADL of one application start-up phase or run phase is ADL1, the one application start-up or run will cause interference to the driver, but the interference is small. The driver can pay most attention to the vehicle driving, and timely deal with emergency.

ADL2 may indicate that the application will draw part of the driver's attention. In the case where ADL of one application start-up phase or run phase is ADL2, the one application start-up or run may cause a disturbance to the driver. But the driver can still pay partial attention to the vehicle driving to timely deal with the non-extreme emergency.

ADL3 may indicate that the application will draw most of the driver's attention. In the case where ADL of one application start-up phase or run phase is ADL3, the one application start-up or run will cause interference to the driver and the interference will be large. The driver can only pay a small amount of attention to the vehicle driving, and emergency situations are difficult to deal with in time, so that the driver cannot realize safe driving.

ADL4 may indicate that the application will draw the driver's primary attention. When a driver starts an application with ADL4 in the starting stage or the central control device runs an application with ADL4 in the running stage, the driver can only pay secondary attention to the driving of the vehicle, so that the driver can only respond to the driving operation request in a non-high frequency and non-rapid manner.

ADL5 may indicate that the application will be fully attracting the driver's attention. When the driver starts an ADL5 application at the start-up stage or the central control device runs an ADL5 application at the run-up stage, the driver usually draws all attention on this application, and it is difficult to pay attention to the vehicle driving, which results in that the driver cannot drive the vehicle at all.

The classification of ADL into the six classes ADL 0 to ADL5 is only an exemplary illustration, and should not be construed as limiting the present application. ADLs may also be classified into more or less levels depending on the degree to which the application is directed to driver distraction.

The central control device may evaluate which level the ADL applied in the start-up phase is and which level the ADL applied in the run-up phase is. The central control device may then store the ADL for the application in the start-up phase and the run phase. Thus, when the central control device detects ARL change in the running process of the vehicle, the central control device can inquire about the ADL of the application, so that whether the application is hidden or not can be quickly determined.

For example, the central control device may evaluate the ADL of the application in the startup phase in combination with the application class and the operational complexity of the application in the startup phase.

In the following, the ADL includes six levels ADL0 to ADL5 as an example, and the central control device evaluates the ADL applied in the start-up phase.

(1) When the operation of starting the application is detected to be simple and the application is a driving assistance application, the central control device can determine that the ADL of the application in the starting stage is ADL0. The simple operation of starting the application may mean that the operation is single, or that the simple operation is repeated, or that the operation is voice operation. For example, the driving mode switching application is started through the voice command, so that the voice switching driving mode is simple to operate, and the driving mode switching application is a driving assistance application, and the ADL of the voice switching driving mode can be ADL0. The ADL of the voice switching driving mode belongs to the ADL of the driving mode switching application in the starting stage.

(2) When the simple operation of starting the application is detected, and the application is a non-driving auxiliary application (such as a vehicle control application and a life entertainment application), the central control device can determine that the ADL of the application in the starting stage is ADL1. For example, by starting the window control application through a voice command, the window opening operation through voice is simple, and the window control application is a vehicle control application (namely, a non-driving auxiliary application), and the ADL of the window opening operation through the voice command can be ADL1. The ADL for opening the window by voice command operation belongs to the ADL of the window control application in the starting stage.

(3) When detecting that the operation of starting the application is moderately complex and the application is a driving assistance type application, the central control device may determine that the ADL of the application in the starting stage is ADL1. The above-mentioned operations for starting the application may represent operations as irregular combinations of a plurality of simple actions, or require a simple action brain to make a decision. For example, starting a navigation application by voice instruction and realizing voice setting of a navigation route requires a driver to decide a navigation destination. The above operations are moderately complex, and the navigation application is a driving assistance-type application, and the ADL for voice start and setting of the navigation route may be ADL1. The ADL for voice-initiated and navigation route setup belongs to the ADL for navigation applications in the initiation phase.

(4) When detecting that the operation of starting the application is moderately complex and the application is a non-driving assistance type application, the central control device may determine that the ADL of the application in the starting stage is ADL2. For example, manually launching a music application by touching a music application icon on a center screen requires the driver to look for the music application icon on the center screen and free up his hand to touch the music application icon. The above operations are moderately complex and the music application is a life entertainment application (i.e., a non-driving assistance application), the ADL of the voice-enabled music application may be ADL2. The ADL of a speech-enabled music application belongs to the ADL of the music application at the start-up stage.

(5) When detecting that the operation of starting the application is complex and the application is a driving assistance application, the central control device can determine that the ADL of the application in the starting stage is ADL2. The above described complexity of the operation of launching an application may indicate that the operation has certain skill requirements or requires complex brain decisions. For example, manually inputting a location on a navigation application interface displayed on a center screen to set a navigation route requires a driver to make text editing at a specified location on the center screen. The above operation is complex, and the navigation application is a driving assistance application, the ADL for manually inputting the place setting navigation route may be ADL2. The ADL for manually inputting a place to set a navigation route belongs to the ADL at the navigation application start stage.

(6) When detecting that the operation of starting the application is complex and the application is a non-driving assistance application, the central control device can determine that the ADL of the application in the starting stage is ADL3. For example, initializing a game application on a central control screen requires a driver to find an operation control for initializing the game application and free a hand to click on the operation control on the central control screen. The above operation is complex, and the game application is a life entertainment application (i.e. a non-driving assistance application), the ADL for initializing the game application may be ADL3. The ADL that initializes the game application belongs to the ADL at the game application start stage.

The above description of the operation complexity is divided into simple, medium-level, and complex operation complexity in determining the operation complexity is merely an exemplary description, and should not be construed as limiting the present application. The operational complexity may also be partitioned according to other partitioning methods.

The central control device can evaluate the ADL of the application in the operation stage according to whether the application needs user operation, operation complexity, attention attraction degree to a driver and application type in the operation process.

Taking ADL including six levels ADL 0-ADL 5 as an example, the central control device evaluates various conditions of ADL applied at the run stage.

(1) In the case that the application requires user operation during running, the central control device may detect the complexity of the operation. The central control device may evaluate the ADL of the application at the run-time in conjunction with the complexity of the operation and the application class of the application at the run-time. The higher the operation complexity of the application in the operation stage, the more attention the driver needs to pay to operate the application when the application is in the operation stage. The greater the distraction of the application to the driver during the run phase, i.e. the greater the ADL applied during the run phase.

(1.1) when it is detected that the application is simple to operate in the run phase and the application is a driving assistance-type application, the control device may determine that the ADL of the application in the run phase is ADL0. For example, a navigation application at the speech control run phase switches navigation routes, requiring the driver to select one of a plurality of navigation route options provided by the navigation application. The operation is simple, and the navigation application is a driving assistance application, and the ADL of the voice switching navigation route is ADL0. The ADL of the voice-switched navigation route belongs to the ADL of the navigation application at the run-time.

(1.2) when the operation of the application in the operation stage is detected to be simple, and the application is a non-driving auxiliary application, the central control device can determine that the ADL of the application in the operation stage is ADL1. For example, a music application switching song at the speech control operation stage requires the driver to speak a voice instruction for a specified switching song. The above operation is simple, and the music application is a living entertainment application (i.e., a non-driving assistance application), the ADL of the voice switching song may be ADL1. The ADL of the voice-switched song belongs to the ADL of the music application at the run-time.

(1.3) when it is detected that the operation of the application in the operation phase is moderately complex and the application is a driving assistance-type application, the center control device may determine that the ADL of the application in the operation phase is ADL2. For example, adjusting a rear view mirror using a rear view mirror adjustment application requires the driver to view the rear view mirror and adjust the rear view mirror to the proper orientation. The above operations are moderately complex and the mirror adjustment application is a driving assistance type application, the ADL of the adjustment mirror may be ADL2. Adjusting the ADL of the mirror belongs to the ADL of the mirror adjusting application in the run phase.

(1.4) when it is detected that the operation of the application in the operation phase is moderately complicated and the application is a non-driving assistance type application, the center control device may determine that the ADL of the application in the operation phase is ADL3. For example, voice calls using voice telephony applications require the driver to communicate with the opposite end of the call. The voice communication is a moderately complex operation, and the voice telephone application is a life entertainment application (i.e. a non-driving assistance application), the ADL of the voice call may be ADL3. The ADL for voice calls belongs to the ADL for voice telephony applications in the run phase.

(1.5) when it is detected that the operation of the application in the operation phase is complex and the application is a driving assistance type application, the central control device may determine that the ADL of the application in the operation phase is ADL4.

(1.6) when it is detected that the operation of the application in the operation stage is complex and the application is a non-driving assistance type application, the central control device may determine that the ADL of the application in the operation stage is ADL5. For example, manual editing of information using an information application requires a driver to make text edits at specified locations on a center screen. The operation is complex, the information application is a life entertainment application, and the ADL for manually editing the information can be ADL5. The ADL for manually editing information belongs to the ADL for the information application at the run-time.

The above method for determining the complexity of the operation is one of simple, medium and complex, and reference may be made to the above method for evaluating the complexity of the operation of the start application. And will not be described in detail here.

(2) Under the condition that the application does not need user operation in the running process, the central control equipment can judge whether visual attraction and the influence duration of visual attraction or non-visual attraction can be generated in the running process. The central control device may evaluate the ADL of the application at the run stage in combination with the duration of the impact of visual or non-visual attraction generated by the application during the run, and the application category. The longer the visual attraction or non-visual attraction of the application is generated in the operation stage, the more attention the driver needs to pay for operating the application when the application is in the operation stage. The greater the level of attention paid to the driver by the application during the run phase, i.e. the greater the ADL applied during the run phase.

(2.1) upon detecting that the application will generate a short time visual attraction to the user during the run phase and that the application is a driving assistance type application, the central control device may determine that the ADL of the application during the run phase is ADL0. For example, a reverse assistance application displays reverse images while the vehicle is reversing, creating a short visual appeal to the driver while the driver is reversing. The reversing assistance application is a driving assistance application, and the ADL for displaying the reversing image may be ADL0. The ADL for displaying the reversing image belongs to the ADL of reversing auxiliary application in the operation stage.

(2.2) when it is detected that the application will generate a short-time visual attraction to the user in the operation stage, and the application is a non-driving assistance type application, the central control device may determine that the ADL of the application in the operation stage is ADL1. For example, an information application displaying an information prompt may create a short visual appeal to the driver. The information application is a life entertainment application (i.e. a non-driving auxiliary application), and the ADL for displaying the information prompt may be ADL1. The ADL displaying the information cues belongs to the ADL of the information application at the run-time.

(2.3) when it is detected that the application generates long-time visual attraction to the user in the operation stage, and the application is a driving assistance type application, the central control device may determine that the ADL of the application in the operation stage is ADL1. For example, navigation applications display navigation routes that create long-term visual appeal to the driver. The navigation application is a driving assistance type application, and the ADL displaying the navigation route may be ADL1. The ADL displaying the navigation route belongs to the ADL of the navigation application in the run-time.

(2.4) when it is detected that the application generates long-time visual attraction to the user in the operation stage, and the application is a non-driving assistance type application, the central control device may determine that the ADL of the application in the operation stage is ADL2. For example, video applications play video, which may create long-term visual appeal to the driver. The video application is a life entertainment application (i.e. a non-driving assistance application), and the ADL for playing the video may be ADL2. The ADL that plays the video belongs to the ADL that the video application is in the run-time.

(2.5) upon detecting that the application is in the run-time period and is a driving assistance type application, the central control device may determine that the ADL of the application in the run-time period is ADL0. For example, a reverse assistance application may provide a reverse voice prompt when the vehicle is reversing, which may create a short audible (i.e., non-visual) attraction to the driver when reversing. The reverse-driving assistance application is a driving assistance application, and the ADL providing the reverse-driving voice prompt may be ADL0. The ADL for providing the reversing voice prompt belongs to the ADL of the reversing auxiliary application in the operation stage.

(2.6) when it is detected that the application will generate a short-time non-visual attraction to the user in the operation stage, and the application is a non-driving assistance type application, the central control device may determine that the ADL of the application in the operation stage is ADL1. For example, weather applications voice broadcast weather information may create a short audible appeal to the driver. The weather application is a life entertainment application (namely a non-driving auxiliary application), and the ADL of the voice broadcasting weather information can be ADL1. The ADL for broadcasting weather information by voice belongs to the ADL of the weather application in the operation stage.

(2.7) when it is detected that the application will generate a long non-visual attraction to the user in the operation phase and the application is a driving assistance type application, the central control device may determine that the ADL of the application in the operation phase is ADL0. For example, the driving assistance application performs voice broadcasting in the case of too close a following distance, lane departure, etc. during the running of the vehicle to assist the driver in driving. The voice broadcasting sustainability for assisting the driver to drive exists in the whole driving process, and long-time hearing attraction can be generated for the driver. It can be understood that the voice broadcast for assisting the driver to drive can not generate visual attraction to the driver, so that the driver can not be influenced to observe the road conditions around the vehicle in the driving process of the vehicle, and various emergency situations can be timely dealt with. The voice broadcast for assisting the driver to drive can prompt the driver to pay attention to the vehicle drive, and the driver is not distracted from the vehicle drive. Therefore, the ADL of the voice broadcast for assisting the driver to drive may be ADL0. The ADL of the voice broadcast for assisting the driver driving belongs to the ADL of the driving assistance application in the running process.

(2.8) when it is detected that the application will generate a long non-visual attraction to the user in the operation stage, and the application is a non-driving assistance type application, the central control device may determine that the ADL of the application in the operation stage is ADL1. For example, a music application playing music may produce a prolonged audible attraction to the driver. The music application is a life entertainment application (i.e. a non-driving assistance application), and the ADL for playing music may be ADL1. The ADL playing music belongs to the ADL of the music application at the run-time.

It should be noted that, the method for determining the duration of influence of visual attraction or non-visual attraction applied in the operation phase in the embodiment of the present application is not limited. In one possible implementation manner, the central control device may determine the length of the influence duration according to whether the influence duration exceeds a preset duration threshold. When the influence duration exceeds a preset duration threshold, the central control equipment can determine that the influence duration is longer. When the influence duration does not exceed the preset duration threshold, the central control device can determine that the influence duration is shorter. The predetermined duration threshold may be, for example, 10 seconds, 20 seconds, 1 minute, etc. The size of the duration threshold is not limited in the embodiment of the present application.

The above description of evaluating an ADL of an application in a startup phase and an ADL of an application in a run phase is merely illustrative and should not be construed as limiting the present application.

The above evaluation of the specific size of the ADL applied in the start-up phase and the specific size of the ADL applied in the run phase is only illustrative of the present application and should not be construed as limiting the present application. The method for evaluating the ADL applied in the startup phase by adopting other factors is not limited to the complexity of the operation and the application type of the application in the startup phase, and is within the protection scope of the application as long as the method is based on the same inventive concept provided by the application. The method for evaluating the ADL of the application in the operation stage by using other factors is not limited to the method for evaluating the ADL of the application in the operation stage by using whether the application needs user operation in the operation stage, the operation complexity, the attention attraction degree of a driver and the application type, and is within the protection scope of the application as long as the method is based on the same inventive concept provided by the application.

In some embodiments, there may be multiple ADLs for an application in the startup phase.

An application may have a number of different modes of activation. For example, an application icon of an application is displayed on the center control screen. The center control screen may launch the application in response to a touch operation acting on the application icon. The central screen may also launch the application in response to voice instructions for launching the application.

The different starting modes require different operations by the user, so that the degree of distraction to the driver may also be different. For example, the manner of starting an application through an application icon requires a driver to find the application icon on a center control and perform a touch operation. The operating complexity of the above-described start-up method is obviously lower than the operating complexity of starting up an application by means of a voice command. That is, the ADL of the application at the start-up stage may include an ADL that starts the application based on the application icon and an ADL that starts the application based on the voice instruction. The ADL for starting the application based on the application icon is larger than the ADL for starting the application based on the voice command.

In some embodiments, the central control device may hide the application icon on the central control screen according to the evaluated ARL and the application hiding policy, but keep the function of the voice command launch application available. In this way, the driver has no opportunity to operate the application icon at the center screen, and thus is not distracted by touching the application icon to launch the application. The driver can still start the application by voice commands.

In other embodiments, the central control device may hide the application icon on the central control screen according to the evaluated ARL and the application hiding policy, and close the function of the voice command to start the application.

As can be seen from the above embodiments, the central control device 100 may implement the hidden part of the entrance of the starting ADL and open the entrance of the other part of the starting ADL according to the ADL applied at the corresponding starting stage under different starting modes. This can avoid the driver from starting the application in a manner that is distracting to a high degree, thereby enabling the driver to put sufficient attention on the driving of the vehicle and improving driving safety.

In some embodiments, there may be multiple ADLs for an application at run-time.

An application may provide multiple functions. For example, the information application may provide a function of displaying information prompts when information is received, and may also provide a function of editing and transmitting information.

Wherein the degree of distraction of the driver from the different functions provided by one application may be different. Then, the ADL of an application at the run-time may include multiple ADLs of the run-time for multiple functions provided by the application. For example, information applications display information cues that generally create a short visual appeal to the driver, with a lesser degree of distraction to the driver. The function of editing and transmitting information provided by the information application requires the driver to edit text at a designated position on the center screen, which is a great distraction to the driver. It can be seen that the ADL of the information application at the run-time may include an ADL that displays functions of the information provision and an ADL that edits and transmits the information. The ADL of the function of displaying information is smaller than that of the function of editing and transmitting information.

In one possible implementation, the central control device may determine the ADL of an application at the run stage according to ADLs of a plurality of functions included in the application at the run stage. For example, the central control device may determine the ADL of the function with the greatest ADL in the one application as the ADL of the one application in the run phase. The method for determining the ADL of one application in the operation stage according to the ADL of a plurality of functions included in the one application in the operation stage is not limited in the embodiments of the present application. The central control device may determine whether the ADL applied in the operation stage is too large based on the evaluated ARL, making it difficult for the driver to pay sufficient attention to the driving of the vehicle. The central control device may then hide the application that the ADL is too large at the run stage, i.e. refuse to run the application. If the application is running, the refusal to run the application may indicate that the central control device stops running the application. If the application is not in the running stage, the refusal to run the application can indicate that the central control device refuses to respond to the operation of starting the application by the user.

In another possible implementation, the central control device may be individually hidden from the functions provided by one application. I.e. one function in one application is hidden from the driver's use of other functions in the one application. The central control device can respectively judge whether the ADL of a plurality of functions in the application is too large in the operation stage according to the ARL obtained through evaluation, so that a driver is difficult to pay enough attention to the vehicle driving. The central control device may then hide functionality in the application that is too large for the ADL at run-time, i.e. refuse to provide it. If the function with the oversized ADL in the operation stage is in the operation stage, the rejection of providing the function may indicate that the central control device stops running the application program corresponding to the function, and the function is closed. If the function with the oversized ADL in the operation stage is not in the operation stage, the rejection of providing the function may indicate that the central control device refuses to respond to the operation of starting the function by the user.

It will be appreciated that the driver's attention is limited and that it may be difficult to pay sufficient attention to the vehicle driving when the driver is paying too much attention to the application of the central control device. Difficulty in drawing sufficient attention on vehicle driving may mean that after a portion of the driver's attention is drawn to aspects other than vehicle driving (e.g., application of a central control device), the driver can draw less attention on vehicle driving than the estimated ARL demand. When it is difficult to pay sufficient attention to the driving of the vehicle, it is difficult for the driver to cope with the sudden situation in time, and driving accidents are likely to occur.

Thus, the higher the demand for driver attention by the vehicle driving, the less attention the driver should be directed to other aspects than the vehicle driving. That is, the larger the ARL, the smaller the ADL the more applications the central control device can hide, and the smaller the ADL of the application that is not hidden. Among other things, applications where the more ads the central control device hides, the smaller may include: the more application icons of the applications with smaller ADL in the starting stage are hidden on the central control screen, and the more applications with smaller ADL in the running stage are stopped.

In some embodiments, where there is only a driver in the front row of the vehicle, the center control device is typically controlled and used by the driver. Considering the impact of the applications of the central control device on the driver's attention, the central control device may hide one or more applications from the evaluated ARL and ADL of the applications, thereby reducing the chance of the driver putting attention to the applications on the central control device.

Referring to fig. 1, fig. 1 illustrates a schematic view of a scene of a hidden application of a central control device in a case where only a driver is present in a front row in a vehicle.

As shown in fig. 1, interface 211 illustrates an exemplary number of application icons displayed on a center screen of the center control device when the vehicle is in a driving state of state 1. Interface 212 illustrates the number of application icons displayed on the center screen of the center control device when the vehicle is in state 2 in the driving state. Interface 213 illustrates the number of application icons displayed on the center screen of the center control device when the vehicle is in state 3 in the driving state. In the process of changing the driving state from the state 1 to the state 2 and then to the state 3, the requirement of the vehicle driving on the attention of the driver is gradually increased. I.e. the ARL corresponding to state 1 is smaller than the ARL corresponding to state 2. The ARL corresponding to state 2 is less than the ARL corresponding to state 3.

Comparing the interface 211, the interface 212 and the interface 213, it can be seen that the applications displayed on the central control screen gradually decrease with the increase of ARL. The central control device may hide an application icon of an application with an oversized ADL in the startup phase according to the ARL and the ADL applied in the startup phase (e.g., an ADL for starting the application based on the application icon). Therefore, when the attention of the driver is required to be increased in the driving process, the application icons displayed on the central control screen are reduced, so that the situation that the driver is distracted due to the operation of the application icons on the central control screen and is difficult to pay enough attention to the driving of the vehicle is reduced.

Conversely, the application displayed on the central screen may be progressively increased as the ARL decreases. In this way, the central control device can display more application icons so that the driver can use the applications on the central control device under the condition that the driver only needs to pay a small amount of attention to the driving of the vehicle to ensure safe driving. When the method judges that the driver can scatter enough attention to use the application on the central control equipment, the application can still be provided for the driver to use, and the use experience of the application on the central control equipment used by the driver is not affected.

For example, if the driving state corresponding to the state 1 is a driving state in which the vehicle is stationary, the central control device may display application icons of all applications in the central control device on the central control screen. In the process of changing the driving state from the state 1 to the state 2 and then to the state 3, the running speed of the vehicle gradually increases, and other factors influencing the evaluation of the ARL are basically unchanged, so that the central control device can determine that the ARL gradually increases and hide application icons of more applications with smaller ADL in the starting stage. It can be seen that the number of application icons displayed on the central control screen may decrease as the speed of travel increases.

For another example, the driving state corresponding to the state 1 is a driving state in which the automatic driving mode is on and the level of the automatic driving mode is at the highest level. In the case where the level of the automatic driving mode is at the highest level, the driver may not need to perform any driving operation during the running of the vehicle. When the driving state of the central control device is state 1, application icons of all applications in the central control device can be displayed on the central control screen. In the process of changing the driving state from the state 1 to the state 2 and then to the state 3, the level of the automatic driving mode of the vehicle gradually decreases, the driving operation of the driver is required to be more and more in the driving process, and other factors influencing the evaluation of the ARL are basically unchanged, so that the central control device can determine that the ARL gradually increases and hide application icons of more applications with smaller ADL in the starting stage. It can be seen that the number of application icons displayed on the center screen may decrease as the level of autopilot mode decreases.

In addition, in the process of changing the driving state from the state 1 to the state 2 and then to the state 3 shown in fig. 1, the ARL gradually rises, and the central control device can stop running more applications with smaller ADLs in the running stage. I.e. the applications running in the central control device decrease as the ARL increases. For example, when ARL is ARL0, the central control device may be running a navigation application, a video application. When an ARL increase is detected, e.g., ARL increases to ARL4, the central control device may stop running the video application. The method can realize the effect of prompting the driver to pay more attention to the vehicle driving by closing the part in operation, so that the situation that the video application disperses the attention of the driver in a plurality of degrees in the operation process can be reduced, and the driving safety is improved.

As can be seen from the scenario shown in fig. 1, the central control device can detect in real time a change in how much attention the driver is required to pay attention to driving the vehicle. When detecting that the driver's attention is required to be increased during driving of the vehicle, the central control device can reduce the number of application icons displayed on the central control screen and reduce the number of running applications in the central control device. This can avoid that the driver's attention is excessively distracted by the application on the central control device, and it is difficult to put sufficient attention on the driving of the vehicle.

In some embodiments, where there is more than one driver in the front row (e.g., there is both a driver and a co-driver in the front row), the center control device is typically commonly controlled and used by the driver and co-driver. Considering the impact of the applications of the central control device on the driver's attention, the central control device may hide one or more applications from the evaluated ARL and ADL of the applications, thereby reducing the chance of the driver putting attention to the applications on the central control device.

However, the vehicle may be driven without the need for the secondary driver to pay attention. In order to reduce the impact of hidden applications on the use of the center control device by the secondary driver, the number of applications that the center control device hides in the case where there are both drivers and secondary drivers in the front row in the vehicle may be less than in the case where the vehicle is in the same driving state but there is only a driver in the front row in the vehicle.

Referring to fig. 2, fig. 2 illustrates a schematic view of a scenario in which the center control device conceals an application in a case where there is a driver and a co-driver in front of a vehicle.

As shown in fig. 2, interface 221 illustrates an exemplary number of application icons displayed on the center screen of the center control device when the vehicle is in a driving state of state 1. Interface 222 illustrates the number of application icons displayed on the center screen of the center control device when the vehicle is in state 2 in the driving state. Interface 223 illustrates the number of application icons displayed on the center screen of the center control device when the vehicle is driving state 3. In the process of changing the driving state from the state 1 to the state 2 and then to the state 3, the requirement of the vehicle driving on the attention of the driver is gradually increased. I.e. the ARL corresponding to state 1 is smaller than the ARL corresponding to state 2. The ARL corresponding to state 2 is less than the ARL corresponding to state 3.

Comparing the interface 221, the interface 222 and the interface 223, it can be seen that the applications displayed on the central control screen gradually decrease with the increase of ARL. The central control device may hide an application icon of an application with an oversized ADL in the startup phase according to the ARL and the ADL applied in the startup phase (e.g., an ADL for starting the application based on the application icon). Therefore, when the attention of the driver is required to be increased in the driving process, the application icons displayed on the central control screen are reduced, so that the situation that the driver is distracted due to the operation of the application icons on the central control screen and is difficult to pay enough attention to the driving of the vehicle is reduced.

The state 1 may be, for example, a driving state corresponding to ARL being ARL 0. When in the state 1, the central control device can display application icons of all applications in the central control device on the central control screen no matter whether the front row in the vehicle has only a driver or not. As can be seen from comparing the interface 211 shown in fig. 1 with the interface 221 shown in fig. 2, the center control device can display the application icons in full amount in the case where only the driver is in the front row in the vehicle and the driver and the co-driver are in the front row in the vehicle.

When changing from state 1 to state 2, the arl increases and the central control device may decrease the application icon displayed on the central control screen. As can be seen by comparing interface 212 shown in fig. 1 with interface 222 shown in fig. 2, the center control device displays more application icons in the case where there is both a driver and a co-driver in the front row of the vehicle than in the case where there is only a driver in the front row of the vehicle in state 2. From state 1 to state 2, the center control device reduces application icons in the case where there is both a driver and a co-driver in the front row of the vehicle less than in the case where there is only a driver in the front row of the vehicle.

Similarly, when changing from state 2 to state 3, the arl increases and the central control device may decrease the application icon displayed on the central control screen. As can be seen by comparing the interface 213 shown in fig. 1 with the interface 223 shown in fig. 2, in the state 3, the center control device displays more application icons in the case where there is both the driver and the co-driver in the front row in the vehicle than in the case where there is only the driver in the front row in the vehicle.

In addition, in the process of changing the driving state from the state 1 to the state 2 and then to the state 3 shown in fig. 2, the ARL gradually rises, and the central control device can stop running more applications with smaller ADLs in the running stage. I.e. the applications running in the central control device decrease as the ARL increases. It will be appreciated that the number of applications that the central control device stops operating with both the driver and the co-driver in the front row of the vehicle may be less than the number of applications that stop operating with only the driver in the front row of the vehicle when the ARL is raised to the same extent.

As can be seen from the scenario shown in fig. 2, the central control device can detect in real time a change in how much attention the driver is required to pay attention to driving the vehicle. When detecting that the driver's attention is required to be increased during driving of the vehicle, the central control device can reduce the number of application icons displayed on the central control screen and reduce the number of running applications in the central control device. Wherein the number of application icons and running applications may be reduced by a smaller amount than in the case where only the driver is in the front row in the vehicle when the degree of change in ARL is the same. The driver can be prevented from being excessively distracted by the application on the central control device, the driver is difficult to pay enough attention to the driving of the vehicle, and the influence of the hidden application on the use of the central control device by the copilot can be reduced.

In the application, when determining the ARL for driving the vehicle and the ADL of each application in the central control device, the central control device may determine which applications are hidden according to a preset application hiding policy.

In some embodiments, the preset application hiding policy may be an application hiding policy table. The application hiding policy table may be referred to as table 1 below.

TABLE 1

It can be seen that the application hiding policy table shown in table 1 above contains ADLs corresponding to applications that need to be hidden under different ARLs in two scenarios where there is only a driver in the front row in the vehicle and there is both a driver and a co-driver in the front row in the vehicle. The central control device may determine the application icon that needs to be hidden on the central control screen according to the application hiding policy table, the ARL for driving the vehicle, and the ADL for the application in the startup phase. The central control device may determine which running applications of the central control device need to be stopped according to the application hiding policy table, the ARL of vehicle driving, and the ADL of the application in the running phase.

The following describes a scene in which only the driver is present in the front row of the vehicle as an example.

For example, when the current ARL is estimated to be ARL2, the central control device may hide the application icons of the applications of ADL4 and ADL5 in the start-up stage on the central control screen according to table 1, and close the applications of ADL4 and ADL5 in the run-up stage.

For another example, when the evaluation results in that the ARL is increased from ARL2 to ARL3, the central control device may further hide the application icon of the application with ADL of ADL3 in the start-up stage on the central control screen according to table 1, and close the application with ADL of ADL3 in the run-up stage.

The application hiding policy table described above is only exemplary and should not be construed as limiting the present application.

In some embodiments, the preset application hiding policy may be to hide an application when the central control device determines that the ADL of the application is greater than an ADL threshold corresponding to the ARL. The central control equipment can store ADL thresholds corresponding to different ARLs. The ADL threshold value for each ARL may be preset. When the ADL of the application in the starting stage is judged to be larger than the ADL threshold corresponding to the ARL, the central control equipment can hide the application icon of the application on the central control screen. When the ADL of the application in the operation stage is judged to be larger than the ADL threshold corresponding to the ARL, the central control equipment can stop operating the application.

Exemplary:

(1) ADL threshold corresponding to ARL0

In a scene where only the driver is in the front row in the vehicle and a scene where both the driver and the co-driver are in the front row in the vehicle, the ADL threshold corresponding to ARL0 may be ADL5.

(2) ADL threshold corresponding to ARL1

In a driver-only scene in the front row of the vehicle, the ADL threshold corresponding to ARL1 may be ADL4.

In a scenario where there are both a driver and a co-driver in the front row in the vehicle, the ADL threshold corresponding to ARL1 may be ADL5.

(3) ADL threshold corresponding to ARL2

In a driver-only scene in the front row of the vehicle, the ADL threshold corresponding to ARL2 may be ADL3.

In a scenario where there are both drivers and co-drivers in the front row of the vehicle, the ADL threshold corresponding to ARL2 may be ADL5.

(4) ADL threshold corresponding to ARL3

In a driver-only scene in the front row of the vehicle, the ADL threshold corresponding to ARL3 may be ADL2.

In a scenario where there are both drivers and co-drivers in the front row of the vehicle, the ADL threshold corresponding to ARL3 may be ADL4.

(5) ADL threshold corresponding to ARL4

In a driver-only scenario in the front row of the vehicle, the ADL threshold corresponding to ARL4 may be ADL1.

In a scenario where there are both drivers and co-drivers in the front row of the vehicle, the ADL threshold corresponding to ARL4 may be ADL3.

(6) ADL threshold corresponding to ARL5

In a driver-only scene in the front row of the vehicle, the ADL threshold corresponding to ARL5 may be ADL0.

In a scenario where there are both drivers and co-drivers in the front row of the vehicle, the ADL threshold corresponding to ARL5 may be ADL2.

It can be seen that the ADL threshold corresponding to ARL may decrease as ARL increases. Thus, the central control device can hide more ADLs and smaller ADLs under the condition that the ARL is larger according to the ADL threshold corresponding to the ARL. The ADL threshold corresponding to the ARL in the front-row driver-only scene is smaller than the ADL threshold corresponding to the same ARL in the front-row driver-and-co-driver-simultaneous scene. Thus, the central control device can hide fewer applications in the scene of the driver and the co-driver in front row in the vehicle at the same time under the condition that the ARL is the same according to the ADL threshold value corresponding to the ARL.

It should be understood that the ADL threshold corresponding to the ADL is only exemplary, and should not be limited to the present application.

The embodiment of the present application does not limit the specific content of the application hiding policy, and is within the protection scope of the present application as long as the specific content is based on the same inventive concept provided by the present application.

A schematic structural diagram of a vehicle provided in an embodiment of the present application is described below.

Referring to fig. 3, fig. 3 schematically illustrates a structural diagram of a vehicle 200 provided in an embodiment of the present application.

As shown in fig. 3, the vehicle 200 includes: a controller area network (controller area network, CAN) bus 21, a plurality of electronic control units (electronic control unit, ECU), an engine 23, a vehicle box (T-box) 24, a transmission 25, a tachograph 26, an antilock system (antilock brake system, ABS) 27, a sensor system 28, an image pickup system 29, a microphone 30, an autopilot system 31, and a traffic pattern management system 32, and the like.

The CAN bus 21 is a serial communication network supporting distributed control or real-time control for connecting the respective components of the vehicle 200. Any component on the CAN bus 21 CAN listen to all data transmitted on the CAN bus 21. The frames transmitted by CAN bus 21 may include data frames, remote frames, error frames, overload frames, different frames transmitting different types of data. In the embodiment of the present application, the CAN bus 21 may be used to transmit data (such as vehicle speed, driving mode, automatic driving level, road congestion degree, etc. driving information) related to the application control method based on the central control device 100 by using the method, and the specific implementation of the method may be referred to in the following detailed description of the method embodiment.

Not limited to the CAN bus 21, in other embodiments, the various components of the vehicle 200 may also be connected and communicate in other ways. For example, the components may also communicate via an on-board ethernet (ethernet) local interconnect network (local interconnect network, LIN) bus, flexRay, and a conventional on-board network system (media oriented systems, MOST) bus, to name a few. The following embodiments are described in terms of the various components communicating via the CAN bus 21.

The autopilot system 31 may be used to provide autopilot functionality. Wherein the autopilot system 31 may provide different levels of autopilot modes. The higher the level of the automatic driving mode, the less driving operations the driver needs to perform during driving, and the less attention the driver needs to pay to the driving of the vehicle.

The driving pattern management system 32 may be used to provide a function of managing the driving pattern of the vehicle 200. Among other things, the driving mode of the vehicle 200 may include a sport mode, a standard mode, an energy saving mode, and the like. When the vehicle 200 switches drive modes, the drive mode management system 32 may adjust the power output of the vehicle by changing the engine 23 fuel injection amount and gearbox operating logic. The vehicle 200 is in different driving modes, and the attention that the driver is required to pay on driving of the vehicle is often different.

The ECU corresponds to a processor or a brain of the vehicle 200 for instructing the corresponding component to perform the corresponding action according to an instruction acquired from the CAN bus 21 or according to an operation input by a user. The ECU may be composed of a security chip, a microprocessor ((microcontroller unit, MCU), a random access memory (random access memory, RAM), a Read Only Memory (ROM), an input/output interface (I/O), an analog/digital converter (a/D converter), and a large scale integrated circuit for input, output, shaping, driving, and the like.

The ECU is of a wide variety and different kinds of ECU can be used to realize different functions.

The plurality of ECUs in the vehicle 200 may include, for example: an engine ECU22A, an ECU22B of a vehicle box (T-box), a transmission ECU22C, a drive recorder ECU22D, an anti-lock brake system (antilock brake system, ABS) ECU 125, and the like.

The engine ECU22A is used to manage the engine, coordinate various functions of the engine, and may be used to start the engine, shut down the engine, and the like, for example. The engine 23 is a device that powers the vehicle 200. An engine is a machine that converts some form of energy into mechanical energy. The vehicle 200 may be used to burn chemical energy of liquid or gas, or to convert electrical energy into mechanical energy and output power to the outside.

The T-box ECU22B is for managing the T-box24.

The T-box24 is primarily responsible for communicating with the internet, providing a remote communication interface for the vehicle 200, and providing services including navigation, entertainment, driving data collection, driving track recording, vehicle fault monitoring, vehicle remote inquiry and control (e.g., lock-out, air conditioning control, window control, engine torque limitation, engine start-stop, seat adjustment, battery level inquiry, oil level, door status, etc.), driving behavior analysis, wireless hot spot sharing, road rescue, anomaly notification, etc.

The T-box24 may be used to communicate with an automotive remote service provider (telematics service provider, TSP) and user (e.g., driver) side electronics to enable vehicle status display and control on the electronics. After the user sends a control command through the vehicle management application on the electronic device, the TSP sends a request command to the T-box24, the T-box24 sends a control message through the CAN bus after obtaining the control command, and realizes control of the vehicle 200, and finally feeds back the operation result to the vehicle management application on the electronic device on the user side. That is, the data read by the T-box24 through the CAN bus 21, such as the data of the vehicle condition report, the driving report, the fuel consumption statistics, the violation inquiry, the position track, the driving behavior, etc., may be transmitted to the TSP background system through the network, and forwarded to the electronic device on the user side by the TSP background system for the user to check.

T-box24 may include, in particular, a communication module and a display screen.

The communication module may be configured to provide wireless communication functions, and support the vehicle 200 to communicate with other devices via wireless local area networks (wireless local area networks, WLAN) (e.g., wi-Fi network, wireless fidelity), bluetooth (BT), global navigation satellite system (global navigation satellite system, GNSS), frequency modulation (frequency modulation, FM), near field wireless communication technology (near field communication, NFC), infrared technology (IR), ultra-wideband (UWB), and other wireless communication technologies. The communication module may also be used to provide mobile communication functions to support the vehicle 200 in communication with other devices via the global system for mobile communications (global system for mobile communications, GSM), universal mobile telecommunications system (universal Mobile telecommunications system, UMTS), wideband code division multiple access (wideband code division multiple access, WCDMA), time division code division multiple access (time-division code division multiple access, TD-SCDMA), long term evolution (long term evolution, LTE), 5G, and future-emerging 6G, among other communication technologies.

The communication module may establish a connection and communicate with a variety of things (vehicle to everything, V2X) communication technology (cellular V2X, C-V2X) and other devices such as servers, user-side electronic devices, etc. via a cellular network based vehicle. The C-V2X may include, for example, V2X (LTE-V2X), 5G-V2X, etc., based on long term evolution (long term evolution, LTE).

The display screen is used to provide a visual interface. One or more displays may be included in the vehicle 200, such as an onboard display disposed in front of the operator's seat, a display disposed above the seat for displaying ambient conditions, a head up digital display (HUD) that projects information onto the windshield, and the like. The display screen for displaying the user interface in the vehicle 200 provided in the subsequent embodiment may be a vehicle-mounted display screen disposed beside the seat, a display screen disposed above the seat, a HUD, or the like, which is not limited herein. The user interface displayed on the display screen in the vehicle 200 may be specifically described with reference to the following embodiments, and will not be described in detail herein.

T-box24 may also be referred to as a central control device, a vehicle system, a telematics device, a vehicle gateway, etc., as embodiments of the present application are not limited in this regard. The display screen of the T-box24 may also be referred to as a center control screen.

In the present application, an application may be installed in the T-box24, and various services are provided through the installed application. The T-box24 may control the above applications, conceal one or more applications according to the driver's attention demand by the vehicle driving, thereby reducing the impact of the above applications on the driver's attention and improving driving safety.

The transmission ECU22C is for managing the transmission.

The transmission 25 may be used as a mechanism for varying the rotational speed and torque of the engine, which can fix or shift the ratio of the output shaft to the input shaft. The transmission 25 components may include a variable speed drive, an operating mechanism, a power take off mechanism, and the like. The main function of the variable speed transmission mechanism is to change the numerical value and direction of torque and rotating speed; the main function of the control mechanism is to control the transmission mechanism to realize the change of the transmission ratio of the transmission, namely the gear shift, so as to achieve the purposes of speed change and torque conversion.

The event data recorder ECU22D is for managing the event data recorder 26.

The components of the tachograph 26 may include a host computer, a vehicle speed sensor, data analysis software, and the like. The automobile data recorder 26 is an instrument for recording the image and sound of the vehicle during running, including the information about the running time, speed, position, etc. In the embodiment of the present application, when the vehicle runs, the vehicle speed sensor collects the wheel rotation speed, and sends the vehicle speed information to the vehicle recorder 26 through the CAN bus.

The ABS ECU125 is for managing the ABS27.

The ABS27 is configured to automatically control the magnitude of the braking force of the brake so that the wheels are not locked during braking of the vehicle, and to ensure that the adhesion between the wheels and the ground is maximized in a state of rolling and sliding. In the braking process, when the electronic control device judges that the wheels tend to lock according to the wheel rotating speed signals input by the wheel rotating speed sensor, the ABS enters an anti-lock braking pressure adjusting process.

The sensor system 28 may include: acceleration sensor, vehicle speed sensor, vibration sensor, gyro sensor, radar sensor, signal transmitter, signal receiver, etc. The acceleration sensor and the vehicle speed sensor are used to detect the speed of the vehicle 200. The shock sensor may be disposed under the seat, in the seat belt, in the seat back, in the operator panel, in the air bag, or in other locations for detecting whether the vehicle 200 is crashed and where the user is located. The gyroscopic sensor may be used to determine a motion pose of the vehicle 200. The radar sensor may include a lidar, an ultrasonic radar, a millimeter wave radar, or the like. The radar sensor is used to emit electromagnetic waves to irradiate a target and receive echoes thereof, thereby obtaining information of a distance, a distance change rate (radial velocity), an azimuth, an altitude, and the like of the target to an electromagnetic wave emission point, thereby identifying other vehicles, pedestrians, roadblocks, and the like near the vehicle 200. The signal transmitter and the signal receiver are used for receiving signals, which can be used for detecting the position of the user, and the signals can be ultrasonic waves, millimeter waves, laser, etc.

The camera system 29 may include a plurality of cameras for capturing still images or video. The camera in the camera system 29 may be disposed at a front, rear, side, in-vehicle, etc., so as to facilitate functions such as driving assistance, driving recording, panoramic looking around, in-vehicle monitoring, etc.

The sensor system 28, the camera system 29 may be used to detect the surrounding environment (e.g., the number of surrounding pedestrians, the number of surrounding vehicles, the congestion level of the road, etc.), to facilitate the vehicle 200 making corresponding decisions to cope with the environmental changes, such as may be used in the automated driving phase to perform tasks focused on the surrounding environment.

A microphone 30, also called "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or outputting a voice command, the user can sound near the microphone 30 through the mouth, inputting a sound signal to the microphone 30. The vehicle 200 may be provided with at least one microphone 30. In other embodiments, the vehicle 200 may be provided with two microphones 30, and may perform a noise reduction function in addition to collecting sound signals. In other embodiments, the vehicle 200 may also be provided with three, four, or more microphones 30, forming a microphone array, enabling collection of sound signals, noise reduction, identification of sound sources, directional recording functions, etc.

In addition, the vehicle 200 may also include multiple interfaces, such as a USB interface, an RS-232 interface, an RS485 interface, etc., that may be externally connected to a camera, a microphone, an earphone, and a user-side electronic device.

It will be appreciated that the configuration illustrated in the embodiments of the present application does not constitute a specific limitation on the vehicle system. The vehicle 200 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

For example, the vehicle 200 may also include separate memories, batteries, lights, wipers, dashboards, audio, vehicle terminals (transmission control unit, TCU), auxiliary control units (auxiliary control unit, ACU), intelligent access and start systems (passive entry passive start, PEPS), on Board Units (OBU), body control modules (body control module, BCM), charging interfaces, and the like.

The central control device according to the embodiment of the present application may be the T-box24 in the vehicle 200 shown in fig. 3. The function of the central control device may be as described with reference to the embodiment shown in fig. 3.

The following specifically describes a schematic structural diagram of a central control device provided in the present application.

Referring to fig. 4, fig. 4 schematically illustrates a structural diagram of a central control device 100 according to an embodiment of the present application.

The central control device 100 may include an application lifecycle management module 410, an application information management module 420, an application icon management module 430, a driving attention demand level assessment module 440, and a driving information collection module 450. Wherein:

the application lifecycle management module 410 can be used to manage the starting, running, and closing of applications. In response to an operation to launch an application, the application lifecycle management module 410 can create a process for the application for launching the application. In response to an operation to close an application, the application lifecycle management module 410 can end the process of the application. A lifecycle may refer to a process of an application from creation to end. In some embodiments, the application lifecycle management module 410 can create multiple processes for an application. The multiple processes may be independent and correspond to multiple functions in the application. The end of the lifecycle of one process may not affect the operation of other processes in the same application.

The application information management module 420 may be used to manage and store information for all applications in the central control apparatus 100. For example, the name of the application, the application icon, the developer, the category, the ADL of the application at the launch stage, the ADL of the application at the run stage, and so on. In some embodiments, there are a number of different ways of starting up the application. The application information management module 420 may contain ADLs that are applied at the startup phase in different startup manners. In some embodiments, an application may provide multiple functions. The application information management module 420 may contain ADLs for different functions in the application at the run-time.

In one possible implementation, the central control device 100 installs an application, and the central control device 100 may evaluate the ADL of the application in the start-up phase and the ADL in the run phase. The application information management module 420 in the central control apparatus 100 may then store the ADL of the one application in the start-up phase and the ADL in the run phase in order to determine whether to hide the one application later in the driving process.

In another possible implementation, the ADL of the respective application at the start-up phase and the ADL at the run phase may be evaluated by other devices, for example, by a cloud server. The cloud server may store an ADL of each application in a startup phase and an ADL in a run phase. The central control apparatus 100 installs one application, and the central control apparatus 100 may acquire an ADL of the one application in a start-up phase and an ADL in a run phase from the cloud server and store the ADLs. The method of obtaining the ADL applied in the start-up phase and the ADL applied in the run phase by the central control apparatus 100 according to the embodiment of the present application is not limited.

The application icon management module 430 may be used to manage application icons displayed on a central control screen. For example, the application icon management module 430 may adjust the location, size, display style of the application icon displayed on the center screen. And, the application icon management module 430 may hide or resume displaying the application icons on the central control screen. The application icons can be used for starting the application corresponding to the application icons.

The driving information collection module 450 may be used to collect driving information of the vehicle 200 during driving. The driving information may include one or more of the following: vehicle speed, driving mode, whether or not to turn on an automatic driving mode, the level of the automatic driving mode, the road type (e.g., urban road, rural mountain road, highway, etc.), the degree of curve of the road, the number of pedestrians on the road, the number of vehicles on the road, the degree of congestion of the road, and the like. The driving information collecting module 450 of the central control device 100 may obtain driving information from the components of the vehicle 200 shown in fig. 3, such as the vehicle recorder 26, the sensor system 28, the camera system 29, the self-driving system 31, and the driving pattern management system 32. The implementation manner in which the driving information collecting module 450 obtains the driving information is not limited in the embodiment of the present application.

The driving attention demand level evaluation module (ARL evaluation module) 440 may be configured to evaluate the ARL of the vehicle driving based on the driving information collected by the driving information collection module 450, so as to determine the level of attention demand of the driver by the current vehicle driving. The implementation method of the driving attention demand level evaluation module 440 to evaluate ARL may refer to the description of the evaluation of ARL in the foregoing embodiment. And will not be described in detail here.

It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the center control apparatus 100. The central control device 100 may include more or fewer modules than shown in fig. 4, or may combine certain modules or split certain modules.

In this application, the ARL evaluation module 440 may evaluate the ARL of a vehicle drive at a fixed or variable time. When the ARL changes, the ARL evaluation module 440 may send the evaluated ARL to the application lifecycle management module 410 and the application icon management module 430. The application lifecycle management module 410 may obtain the ADL of the running application in the central control device 100 at the run phase from the application information management module 420. Based on the received ARL, the ADL of the application at the run-time, and the application hiding policy, the application lifecycle management module 410 can shut down applications that are too large of the ADL at the run-time. For example, the application lifecycle management module 410 may close an application where the ADL at run-time exceeds the ADL threshold corresponding to the ARL. The application icon management module 430 may obtain the ADL of the application at the start-up phase from the application information management module 420. Based on the received ARL, the ADL of the application in the start-up phase, and the application hiding policy, the application icon management module 430 may hide the application icons of the applications with too large ADL in the start-up phase on the central control screen. For example, the application icon management module 430 may hide application icons of applications on the central control screen for which the ADL at the start-up phase exceeds the ADL threshold corresponding to the ARL.

Therefore, the driver can be prevented from being excessively dispersed on the application of the central control device, so that the driver can pay enough attention to the driving of the vehicle under different driving conditions, and the driving safety is improved.

Based on the foregoing vehicle 200 shown in fig. 3 and the central control apparatus 100 shown in fig. 4, a scenario of application control provided in the embodiment of the present application is described below.

Fig. 5A and 5B schematically illustrate a scenario in which the central control apparatus 100 controls an application.

As shown in fig. 5A, the center control device 100 may display a user interface 510 on the center control screen during the driver driving the vehicle. The user interface 510 may include an application icon display area 511. The application icon display area 511 may be used to display application icons of applications installed in the center control device 100. The central control apparatus 100 may evaluate the ARL of the current vehicle driving and determine which application icons of the applications are displayed on the central control screen and which application icons of the applications are hidden according to the ARL, the ADL of the application in the start-up phase, and the application hiding policy.

For example, the center control apparatus 100 evaluates ARL, which is the current vehicle driving, as ARL2. The central control device 100 may hide, on the central control screen, application icons of applications whose ADL exceeds the ADL threshold corresponding to ARL2 in the start-up phase, and display application icons of applications whose ADL does not exceed the ADL threshold corresponding to ARL2 in the start-up phase. The ADL of the application icon (e.g., set application icon, driving mode application icon, game application icon, video application icon, etc.) in the application icon display area 511 shown in fig. 5A does not exceed the ADL threshold corresponding to the ARL2 described above in the startup phase.

The user interface 510 may also include a music play control 512. The music playing control 512 may be a control of a music application that may be used to control the playing of music (e.g., pause playing, continue playing, next, last). The music play control 512 shown in fig. 5A may indicate that "song 1" is playing. I.e. the central control apparatus 100 is running a music application and playing song 1.

The central control apparatus 100 may determine which running applications to stop running and which running applications to continue running according to the evaluated ARL, the ADL of the application in the running phase, and the application hiding policy.

For example, the center control apparatus 100 evaluates ARL, which is the current vehicle driving, as ARL2. The central control device 100 may stop running the application in which the ADL in the operation stage exceeds the ADL threshold corresponding to the ARL2, and continue running the application in which the ADL in the operation stage does not exceed the ADL threshold corresponding to the ARL2. The ADL of the music application in the operation stage does not exceed the ADL threshold corresponding to ARL2. Then the central control apparatus 100 may continue to run the music application in the scenario shown in fig. 5A.

The driver continues driving from the position shown in fig. 5A to the position shown in fig. 5B. As can be seen from comparing fig. 5A and fig. 5B, the driver has fewer pedestrians around the position shown in fig. 5A, the road is unobstructed, the road condition is simpler, and less attention is required to be paid to the driving of the vehicle. The driver has more pedestrians around the position shown in fig. 5B, namely, the driver is about to pass through the zebra stripes and the traffic lights, the road is relatively complex, and the driver needs to pay more attention to the driving of the vehicle and timely deal with the emergency. For example, in the position shown in fig. 5B, the driver needs to concentrate on the distance between the own vehicle and the surrounding vehicles, avoiding the front vehicle from being braked too hard to brake by himself when the following distance is too short. And, the driver still needs to pay attention to the movement of observing peripheral pedestrian, can't in time brake when avoiding the pedestrian to pass through the zebra crossing. It can be seen that the driver needs to pay more attention to driving the vehicle from the position shown in fig. 5A to the position shown in fig. 5B. Then, the center control apparatus 100 evaluates that the ARL is greater at the position of the vehicle in fig. 5B than at the position of the vehicle in fig. 5A.

For example, the central control apparatus 100 evaluates the ARL as ARL4 when the vehicle is located at the position shown in fig. 5B. The central control device 100 may hide, on the central control screen, application icons of applications whose ADL exceeds the ADL threshold corresponding to ARL2 in the start-up phase, and display application icons of applications whose ADL does not exceed the ADL threshold corresponding to ARL2 in the start-up phase. The application icons displayed by the central control apparatus 100 according to the ARL4, the ADL applied in the start-up phase, and the application hiding policy described above may refer to the user interface 520 displayed on the central control screen by the central control apparatus 100 shown in fig. 5B.

As shown in fig. 5B, the user interface 520 may include an application icon display area 521. The application icon display area 521 may contain a setup application icon, a driving mode application icon, a calendar application icon, a tachograph application icon, and a weather application icon. The ADL of the application icon display area 521 shown in fig. 5B, which corresponds to the application at the start stage, does not exceed the ADL threshold corresponding to the ARL4.

As can be seen from comparing the application icon display area 511 shown in fig. 5A with the application icon display area 521 shown in fig. 5B, when the ARL increases, the center control device 100 can hide on the center control screen application icons (such as the game application icon, the video application icon, the memo application icon, and the like shown in fig. 5A) of more applications that are smaller in the startup phase ADL. This can avoid that the driver has difficulty in focusing on the driving of the vehicle due to operating the application icon of the application that would be excessively distracted at the time of start-up, thereby improving driving safety.

The central control apparatus 100 may also stop running the application in which the ADL in the running stage exceeds the ADL threshold corresponding to ARL4, and continue running the application in which the ADL in the running stage does not exceed the ADL threshold corresponding to ARL 4. For example, the ADL of the music application at the run-time exceeds the ADL threshold corresponding to ARL 4. The center control device 100 may stop running the music application.

In one possible implementation, the central control device 100 may close the music application and end the process of the music application.

In another possible implementation, the central control apparatus 100 may stop playing music and display the music play control 522 shown in fig. 5B. That is, the central control apparatus 100 may stop running the music application by temporarily stopping playing music, but does not end the progress of the music application. In this way, the central control apparatus 100 subsequently evaluates that the resultant ARL decreases, and the central control apparatus can resume the process of running the music application again. For example, if the central control apparatus 100 determines that the ADL threshold corresponding to the ARL is greater than or equal to the ADL of the music application in the running stage according to the ARL obtained by the evaluation, the central control apparatus 100 may run the music application again, and continue playing music from the last paused position. The above-described center control device 100 may continue playing music without the user performing the operation of starting the music application again.

In some embodiments, after the central control device 100 hides one or more application icons on the central control screen, a gap may occur in the position where the hidden application icons are located. The central control apparatus 100 may reorder the display positions of the application icons that are not hidden. For example, the center control device 100 may display application icons that are not hidden one by one in the application icon display area on the center control screen in the order of the left-to-right and top-to-bottom arrangement. In other embodiments, the central control device 100 may not change the display position of the application icon that is not hidden.

It will be appreciated that the user interfaces and hidden application icons shown in fig. 5A and 5B are merely exemplary illustrations of the present application and should not be construed as limiting the application control method of the present application.

As can be seen from the above-described scenes shown in fig. 5A and 5B, the center control device 100 can detect in real time a change in how much attention the driver is required to pay attention to driving the vehicle. When detecting that the driver's attention is required to be increased during driving of the vehicle, the central control device can reduce the number of application icons displayed on the central control screen and reduce the number of running applications in the central control device. The driver can not have the opportunity of operating the application which is easy to be distracted in the driving process of the vehicle, the situation that the attention of the driver is excessively distracted by the application on the central control equipment and is difficult to input enough attention in the driving process of the vehicle is avoided, and therefore the driving safety is improved.

In some embodiments, an application may provide multiple functions. The ADLs of different functions may be different. The central control apparatus 100 may evaluate the ARL of the current vehicle driving and hide one or more functions in one application according to the ARL, the ADL of the function, and the application hiding policy. Wherein when some of the functions in one application are hidden, the driver can still continue to use other functions in the one application that are not hidden.

Fig. 6A and 6B schematically illustrate a scenario in which the central control apparatus 100 controls an application.

As shown in fig. 6A, during driving of the vehicle by the driver, the center control device 100 may open the information application in response to an operation to start the information application, displaying a user interface 610 on the center control screen. User interface 610 may be a chat interface with contacts "Zhang Sanj" in an information application. The user interface 610 may include a voice control 611, a text editing control 612, an emoticon control 613, and a further functionality control 614. Wherein:

the voice control 611 may be used to provide functionality for sending voice messages. In response to operation of the voice control 611, the center control device 100 may invoke the microphone to collect voice and send the voice to the contact "Zhang Sano".

Text editing control 612 may be used to provide functionality for sending text messages. In response to operation of the text editing control 612, the center control device 100 may display a keyboard on the center control screen to facilitate a user entering text messages in the text editing control using the keyboard.

The expression control 613 can be used to provide a function of transmitting an expression package. In response to operation of the expression control 613, the central control device 100 may display one or more expression package options to facilitate user selection of one expression.

More functionality controls 614 may be used to trigger the central control device 100 to display controls corresponding to other functionality provided by the information application. Such as a function of transmitting video photos, a function of location sharing, a function of transmitting files, etc.

That is, the above-described information application may provide a function of transmitting a voice message, a function of transmitting a text message, a function of transmitting an expression package, a function of transmitting a video photograph, a function of location sharing, a function of transmitting a file, and the like. Wherein the use of the function of transmitting voice message requires the driver to operate the voice control 611 (e.g., click operation) and speak the voice to be transmitted. Using the function of sending text messages requires the driver to operate text editing control 612 and to edit text using a keyboard provided by central control apparatus 100. Using the send expression package function requires the driver to operate the expression control 613 and select one or more expressions displayed on the center control screen to send. The above function of sending video photos, the function of sharing locations, and the function of sending files all require the driver to operate more functions controls 614, then select a control corresponding to a function, and further execute a corresponding operation to send video photos, or perform location sharing, or send files. It can be seen that the ADL of the function of sending voice messages is low. The ADL of the function of sending text messages, the function of sending expression packages, the function of sending video pictures, the function of sharing positions and the function of sending files is higher.

As shown in fig. 6A, when the vehicle is driven to the position shown in fig. 6A, there are fewer pedestrians around the vehicle, the road is clear, the road condition is relatively simple, and less attention is required to be paid to the driving of the vehicle. That is, the driver may pay more attention to the application of the usage control device 100. The central control device 100 may display the user interface 610 depicted in fig. 6A while running the information application. The driver may use any one of a function of transmitting a voice message, a function of transmitting a text message, a function of transmitting an expression package, a function of transmitting a video photograph, a function of sharing a location, and a function of transmitting a file in the information application.

The driver continues driving from the position shown in fig. 6A to the position shown in fig. 6B. As shown in fig. 6B, when the vehicle is driven to the position shown in fig. 6B, there are many pedestrians around the vehicle, that is, the vehicle passes through the zebra stripes and the traffic lights, the road is relatively complex, and the vehicle needs to pay more attention to driving, so that the emergency situation is timely dealt with. That is, the ARL of the vehicle driving increases from the position shown in fig. 6A to the position shown in fig. 6B, and the driver should not pay excessive attention to the application of the usage control device 100 at the position shown in fig. 6B. The central control apparatus 100 may still keep the information application in an operating state. The central control device 100 may determine the functions to be hidden in the information application according to the ARL obtained by current evaluation, the ADL of each function in the information application, and the application hiding policy.

For example, the central control apparatus 100 may reserve the above-described function of transmitting a voice message, and hide the above-described function of transmitting a text message, function of transmitting an expression package, function of transmitting a video photograph, function of location sharing, function of transmitting a file. The central control apparatus 100 may display the user interface 620 shown in fig. 6B. The user interface 620 can include a voice control 611. As can be seen by comparing the user interface 610 shown in fig. 6A with the user interface 620 shown in fig. 6B, as the ARL increases, the center control device 100 hides the text editing control 612, the emoticon control 613, and the more functionality control 614 on the center control screen. This can avoid the driver from being excessively distracted by using the functions corresponding to the text editing control 612, the expression control 613 and the more function control 614 during the driving of the vehicle, and being difficult to pay sufficient attention to the driving of the vehicle, thereby improving the driving safety. However, since the function of transmitting the voice message requires only a small amount of attention from the driver, it does not cause the driver to have difficulty in focusing on the driving of the vehicle at the position shown in fig. 6B, and thus the center control device 100 can retain the voice control 611 described above. In this way, the driver can still use the function of sending voice messages in the information application.

In some embodiments, the function in the hidden application may stop running the program corresponding to the function in addition to canceling the control corresponding to the display function on the central control screen.

It will be appreciated that the user interfaces and hidden functions shown in fig. 6A and 6B are merely exemplary illustrations of the present application and should not be construed as limiting the application control method of the present application.

As can be seen from the above-described scenarios shown in fig. 6A and fig. 6B, the central control device may individually hide each function provided by one application. Hiding one function in an application may not affect the use of other functions in the application. The central control device can detect in real time the change of how much attention the driver needs to pay attention to when driving the vehicle. When it is detected that the ADL of one function in the application may excessively attract the attention of the driver, so that the attention that the driver can pay in the driving of the vehicle cannot meet the requirements of the ARL of the current driving of the vehicle, the center control device 100 may hide the one function of the application. This can avoid the driver from using this function of the application to cause the attention to be excessively distracted, thereby improving driving safety. The driver can continue to use other functions of the application that are not hidden. The method can reduce the influence of the hidden application on the application in the use of the central control equipment by the driver on the basis of avoiding the excessive distraction of the driver due to the application on the use of the central control equipment.

In some embodiments, the central control device may adjust the display position of the application icon on the central control screen according to the change of the driving information. When driving information changes to make the driver need to pay more attention to driving the vehicle, the central control device may display an icon of an application with a small distraction to the driver on a side of the central control screen close to the driver, and display an icon of an application with a large distraction to the driver on a side of the central control screen far from the driver.

Fig. 6C illustrates a schematic view of another scenario in which the central control apparatus 100 controls an application.

Here, the driving assistance class application is taken as an application with a small degree of distraction to the driver, and the non-driving assistance class application is taken as an application with a large degree of distraction to the driver as an example.

As shown in fig. 6C, the center control device 100 may display a user interface 630 on the center control screen. The user interface 630 may include icons of applications in the central control device 100. For example, the icon of the driving assistance class application 1 to the icon of the driving assistance class application 6, and the icon of the non-driving assistance class application 1 to the non-driving assistance class application 12. The display positions of the icons of the driving assistance class application and the non-driving assistance class application on the user interface 630 may be preset at the time of shipment of the center control device 100, or determined by the installation order of the applications, or determined in response to an operation of adjusting the positions of the icons.

The center control apparatus 100 may acquire driving information of the vehicle during the running of the vehicle. When it is determined that the driving information is changed in a direction in which the driver is required to pay more attention to driving the vehicle, the center control apparatus 100 may adjust the display position of the application icon on the center control screen.

For example, the center control device 100 may display the user interface 640 on a center control screen. The display position of the application icon on the user interface 640 is changed in comparison to the user interface 630. The center control device 100 may display an icon of the driving assistance class application 1 to an icon of the driving assistance class application 6 in the area 641 of the user interface 640. The area 641 may be an area on the center control screen near the driver's side. The center control device 100 may display the icons of the non-driving assistance class applications 1 to the icons of the non-driving assistance class applications 12 in an area other than the area 641 of the user interface 640. The area outside the area 641 of the user interface 640 may be an area on the side of the center screen remote from the driver.

It will be appreciated that the distance between the region 641 and the driver is closer. The driver can operate the application icons in the area 641 more conveniently and quickly. In this way, in the case where the driver needs to pay more attention to the driving of the vehicle, the driver can quickly operate the icon of the application with a small degree of distraction. According to the method, the icons of the application with high distraction degree are displayed on the side, far away from the driver, of the central control screen, so that the influence of the application on the attention of the driver can be reduced better, and the driving safety is improved.

The application shown in fig. 6C is merely exemplary of the application and should not be construed as limiting the application.

The driving information described above varies in a direction that requires the driver to pay more attention to driving the vehicle, and may include one or more of the following: the vehicle speed increases, the level of the automatic driving mode decreases, the congestion degree of the road increases, the number of pedestrians on the road increases, the number of vehicles on the road increases, and the degree of straightness of the road increases.

The manner in which the center control device 100 determines to display the application icon based on the driving information will be described below.

In one possible implementation, the central control apparatus 100 may acquire driving information during the running of the vehicle and evaluate the ARL according to the driving information. The central control apparatus 100 may then determine the display position of the application icon on the central control screen according to the ARL and the ADL of the application described above. Wherein, when the ARL increases, the central control apparatus 100 may move icons of more applications with larger ADLs to an area on the central control screen far from the driver side, and move icons of more applications with smaller ADLs to an area on the central control screen near the driver side.

In an exemplary embodiment, the central control device may move the application icon of the application whose ADL in the start-up phase is less than or equal to the ADL threshold corresponding to the ARL currently evaluated to an area on the central control screen near the driver, and move the application icon of the application whose ADL in the start-up phase is higher than the ADL threshold to an area on the central control screen far from the driver.

In another possible implementation manner, the central control device 100 may store different application icon display manners corresponding to driving information. For example, the application icon display modes corresponding to the different driving information may be stored in the application control table. The display mode of the application icons can be used for indicating the display positions of the application icons on the central control. When the driving information of the vehicle is acquired, the central control device 100 may query the application control table to obtain the display mode of the application icon corresponding to the current driving information. The central control apparatus 100 may display icons of respective applications on the central control screen according to the above-described application icon display manner.

The above manner of displaying the application icons is merely an exemplary illustration, and the center control device 100 may also determine the display positions of the application icons according to the driving information in other manners.

In some embodiments, there are multiple displays in the vehicle 200. The plurality of display screens may be configured at different locations of the vehicle 200 and may be uniformly controlled by the center control device 100. When adjusting the display positions of the application icons according to the change of the driving information, the center control device 100 may adjust the application icons to be displayed on the plurality of display screens. Wherein, when it is detected that the driving information changes in a direction in which the driver is required to put more attention on the driving of the vehicle, the center control apparatus 100 may display an icon of an application of which the degree of distraction is small on the display screen on the side close to the driver, and display an icon of an application of which the degree of distraction is large on the display screen on the side far from the driver. This reduces the attraction of the driver's attention from the above-described application of high distraction, so that the driver can put sufficient attention on the driving of the vehicle, thereby improving driving safety.

In some embodiments, the central control apparatus 100 may combine the above method of adjusting the display position of the application icon with the method of hiding the application icon. For example, when it is detected that the driving information changes in a direction in which the driver is required to pay more attention to the driving of the vehicle, the center control device 100 may adjust the display position of the application icons according to the above-described embodiment, display one or more icons of the application with a small degree of distraction on the center control screen on the side close to the driver, and hide one or more icons of the application with a large degree of distraction on the center control screen. In some embodiments, the central control apparatus 100 may adjust the user interface of the application according to the driving information. An application's user interface may include controls for providing functions of the application. The center control device 100 may adjust the display positions of a plurality of controls for providing the above-described plurality of functions on the user interface according to the driving information and the degree of distraction applied in providing the above-described different functions. For example, when it is detected that the driving information changes in a direction in which the driver is required to put more attention on the vehicle driving, the center control device 100 may display a control corresponding to a function of which the degree of distraction is small on a side close to the driver and a control corresponding to a function of which the degree of distraction is large on a side far from the driver. Optionally, the central control device 100 may further hide a control corresponding to a part of the functions in the user interface of the application according to the driving information. For example, when it is detected that the driving information changes in a direction that requires the driver to put more attention on the driving of the vehicle, the center control device 100 may hide a control corresponding to a function that is highly distracted. The embodiment can reduce the attraction of the functions with large distraction to the driver, and the driver can operate the control corresponding to the functions with small distraction more conveniently and quickly. This can both improve user's use experience to can make the driver to be directed at enough attention on the vehicle driving, improve vehicle driving's security.

Referring to fig. 7, fig. 7 illustrates a flowchart of an application control method according to an embodiment of the present application.

As shown in fig. 7, the method may include steps S711 to S720. The method may be applied to a center control device 100 in a vehicle. As can be seen from the foregoing schematic structure shown in fig. 4, the central control apparatus 100 may include an application lifecycle management module 410, an application information management module 420, an application icon management module 430, a driving attention level (ARL) assessment module 440, and a driving information collection module 450.

Steps S711 to S713: ARL evaluation.

S711, ARL evaluation module 440 may send a driving information acquisition request to driving information collection module 450.

The ARL evaluation module 440 may periodically obtain driving information and perform an ARL evaluation. For example, the ARL evaluation module 440 may request the driving information collection module 450 for acquisition of driving information every a preset period of time and then perform ARL evaluation. The above-mentioned preset period of time may be 1 minute, 2 minutes, or the like. The length of the preset time period is not limited in the embodiment of the present application.

Alternatively, the ARL evaluation module 440 may acquire driving information and perform ARL evaluation at random. The interval between two ARL evaluations by the ARL evaluation module 440 is not limited in this embodiment.

S712, the driving information collecting module 450 may send driving information to the ARL assessment module 440.

In response to the above-described driving information acquisition request, the driving information collection module 450 may collect driving information of the vehicle. The driving information collecting module 450 may obtain driving information from components of the vehicle 200, such as the event data recorder 26, the sensor system 28, the image capturing system 29, the autopilot system 31, and the driving pattern management system 32. The driving information may include one or more of the following: vehicle speed, driving mode, whether or not to turn on an automatic driving mode, the level of the automatic driving mode, the road type (e.g., urban road, rural mountain road, highway, etc.), the degree of curve of the road, the number of pedestrians on the road, the number of vehicles on the road, the degree of congestion of the road, and the like. The specific method by which the driving information collecting module 450 collects driving information to the respective components of the vehicle is not limited in the embodiments of the present application.

The driving information collection module 450 may collect driving information of the vehicle for a period of time before receiving the driving information acquisition request. Illustratively, the driving information collecting module 450 receives the driving information obtaining request at time t 1. The driving information collection module 450 may collect driving information of the vehicle for a period of time T1 before the time T1. For example, the vehicle speed of the vehicle in the T1 period. The size of T1 is not limited in the present application. Alternatively, the driving information collecting module 450 may collect driving information of the vehicle for a period of time after receiving the driving information obtaining request. Alternatively, the driving information collecting module 450 may collect driving information of the vehicle for a period of time before receiving the driving information obtaining request, and driving information of the vehicle for a period of time after receiving the home or information obtaining request. Illustratively, the driving information collecting module 450 receives the driving information obtaining request at time t 1. The driving information collecting module 450 may collect driving information of the vehicle for the period T2. The above-mentioned time T1 is located within the time period T2. The size of T2 is not limited in the present application.

The driving information collection module 450 may send the received driving information to the ARL assessment module 440.

S713, the ARL evaluation module 440 may perform a driving attention demand level (ARL) evaluation based on the driving information and detect an ARL change.

The method of the ARL evaluation module 440 for performing the ARL evaluation according to the driving information may refer to the description of the foregoing embodiment. And will not be described in detail here. The ARL evaluation module 440 may compare the ARL currently evaluated with the ARL previously evaluated to determine if the ARL has changed. For example, the ARL evaluation module 440 may compare the ARL obtained from the current evaluation with the ARL obtained from the previous evaluation to determine whether the ARL obtained from the current evaluation has increased based on the ARL obtained from the previous evaluation. For another example, the ARL evaluation module 440 may compare the ARL obtained from the current evaluation with the ARL obtained from a previous plurality of evaluations.

S714, the ARL assessment module 440 may send an ARL change notification to the application lifecycle management module 410 and the application icon management module 430, the ARL change notification containing the currently assessed ARL.

When an ARL change is detected, the ARL evaluation module 440 can send an ARL change notification to the application lifecycle management module 410 and the application icon management module 430.

Steps S715 to S717: and stopping running the determined application needing to be stopped.

S715, the application lifecycle management module 410 may request the application information management module 420 to obtain the distraction level (ADL) of the currently running application at the run phase in response to the ARL change notification.

S716, the application information management module 420 may send the ADL of the currently running application in the running phase to the application lifecycle management module 410.

S717, the application lifecycle management module 410 may stop running the application with the ADL higher than the ADL threshold corresponding to the ARL according to the ARL and the ADL of the application in the running phase that are currently evaluated.

The application lifecycle management module 410 may determine which running applications need to be stopped according to a preset application hiding policy, so as to avoid that the applications are excessively distracted from the driver during the running process, so that the driver can pay attention to the driving of the vehicle, and the requirements of the ARL obtained by the current evaluation are difficult to meet.

In one possible implementation, the application lifecycle management module 410 may obtain ADL thresholds corresponding to different ARLs. The application lifecycle management module 410 may determine which applications in the run phase have ADLs above the ADL threshold corresponding to the current ARL and stop running the ADL above the ADL threshold corresponding to the current ARL.

Alternatively, the application lifecycle management module 410 may obtain the application hiding policy table shown in table 1 and look up a table to determine which applications need to be stopped.

The applications running as described above may include an application running in the foreground of the center control device 100, and an application running in the background of the center control device 100.

A method for stopping the application from running by the application lifecycle management module 410 is described herein.

In one possible implementation, the applications running in the central control device 100 include application a. When it is determined that the ADL of the application a in the running stage is higher than the ADL threshold corresponding to the current ARL, the application lifecycle management module 410 may close the application a and end the process of the application a. In this way, the user interface of application a is no longer displayed on the central control screen. The background of the central control device 100 also no longer runs the process of application a. This can avoid the application a from distracting the driver during the operation phase so that the driver can put more attention into the vehicle driving, thereby improving driving safety.

In another possible implementation, the applications running in the central control device 100 include application a. When it is determined that the ADL of the application a in the running stage is higher than the ADL threshold corresponding to the current ARL, the application lifecycle management module 410 may suspend running the application a and reserve the process of the application a in the background. That is, when suspending the running of application a, the central control apparatus 100 may cancel the user interface displaying application a on the central control screen and interrupt all tasks of application a in the running process. Application a no longer produces an attraction (e.g., visual attraction, auditory attraction, etc.) to the driver. The process of application a may still exist in the background with the central control device 100.

The application lifecycle management module 410 may store the running data (e.g., user interface data, etc.) of the application a when the application a is suspended for subsequent resuming of the application a.

Further, the ARL evaluation module 440 subsequently evaluates the resultant ARL reduction. When it is determined that the ADL of the application a in the running stage is less than or equal to the ADL threshold corresponding to the ADL obtained by the subsequent evaluation, the application lifecycle management module 410 may continue to run the application a according to the running data of the application a during the suspension running.

Illustratively, the application a is a music application. The music application is running in the central control apparatus 100 playing music. The application lifecycle management module 410 may pause the running of the music application when it detects that the ADL of the music application in the run phase is above the ADL threshold corresponding to the current ARL. The pausing the running music application may include controlling the music application to pause playing music. If a user interface for the music application is displayed on the central screen during the running of the music application, the application lifecycle management module 410 may further comprise closing the user interface for the music application on the central screen. It can be seen that the driver's attention may not be re-directed after the music application is suspended from running.

The application lifecycle management module 410 may store, among other things, data of the music application playing music and displayed user interface data when the music application is in suspension. When the ADL threshold corresponding to the ARL obtained by the subsequent evaluation is again greater than the ADL of the music application in the running stage, the application lifecycle management module 410 may continue to run the music application. According to the above data of music application playing music and displayed user interface data when the music application is suspended, the central control apparatus 100 can continue playing music from the position of music playing when the music application was suspended last time and display the user interface when the music application was suspended last time.

Steps S718 to S720: and hiding the determined application icons needing to be hidden on the central control screen.

S718, the application icon management module 430 may request the application information management module 420 to obtain the ADL of the application at the start-up stage in response to the ARL change notification.

S719, the application information management module 420 may send the ADL of the application in the startup phase to the application icon management module 430.

S720, the application icon management module 430 can hide application icons of applications with ADL higher than the ADL threshold corresponding to the ARL according to the ARL obtained by current evaluation and the ADL of the application in the starting stage, and display application icons of applications with ADL smaller than or equal to the ADL threshold corresponding to the ARL.

The application icon management module 430 may determine which application icons of the applications in the central control device 100 need to be hidden according to a preset application hiding policy, so as to avoid excessive distraction of the driver due to operating the application icons, and make it difficult to pay attention to the vehicle driving to meet the ARL requirement currently evaluated.

In one possible implementation, the application icon management module 430 may obtain ADLs for all applications in the central control device 100 during the startup phase. Upon receiving the ARL change notification, the application icon management module 430 may determine which applications have ADLs in the startup phase that are above the ADL threshold corresponding to the ARL. Then, the application icon management module 430 refreshes the desktop displayed on the central control screen, hides the application icons of the applications with ADL higher than the ADL threshold corresponding to the ARL, and displays the application icons of the applications with ADL less than or equal to the ADL threshold corresponding to the ARL.

In another possible implementation, when the ARL change notification indicates that the ARL increases, the application icon management module 430 may only obtain the ADL of the application at the start-up stage corresponding to the application icon currently displayed on the central screen. The application icon management module 430 may then determine whether the ADL of the applications at the startup stage is above the ADL threshold corresponding to the ARL and hide application icons of applications with ADL above the ADL threshold corresponding to the ARL. It will be appreciated that an increase in ARL indicates that the vehicle is driving with increased attention to the driver, and that the driver should pay less attention to the application of the central control apparatus 100. After the ARL increases, the ADL threshold corresponding to the ARL decreases. Then, the center controlling device 100 may hide application icons of more applications with smaller ADLs at the start-up stage than application icons displayed on the center controlling screen before the ARL is increased.

When the ARL change notification indicates that the ARL is reduced, the application icon management module 430 may only acquire the ADL of the application at the start-up stage that is currently corresponding to the application icon displayed on the center control screen. Then, the application icon management module 430 may determine whether the ADL of the applications in the startup phase is less than or equal to the ADL threshold corresponding to the ARL, and restore the application icon of the application displaying the ADL less than or equal to the ADL threshold corresponding to the ADL. It will be appreciated that a decrease in ARL indicates a decrease in the attention demand of the driver for vehicle driving, and that the driver may be focusing more on the application of the center control device 100. After ARL decreases, the ADL threshold corresponding to ARL increases. Then, the center control device 100 may restore the application icon displaying the application whose ADL is less than or equal to the ADL threshold corresponding to the current ARL, compared to the application icon hidden before the ARL is reduced.

In addition to determining the application icons to be hidden by using the ADL threshold corresponding to the ARL, the application icon management module 430 may determine the application icons to be hidden according to the application hiding policy table shown in the foregoing table 1.

As can be seen from the method shown in fig. 7, the center control device 100 can detect in real time a change in the amount of attention of the driver required for driving the vehicle. When detecting a change in the attention that the driver is required to pay in driving the vehicle, the center control device 100 may adjust the number of application icons displayed on the center control screen and the number of applications running in the center control device. This can avoid that the driver's attention is excessively dispersed by the application on the center control device, and it is difficult to put sufficient attention on the driving of the vehicle, thereby improving the driving safety. And, when it is judged that the driver can be distracted from the aspect other than the driving of the vehicle by the change in the attention of the driver, which is required for the driving of the vehicle, the center control device 100 can restore the partially hidden application, reducing the influence of the hidden application on the use of the center control device by the driver.

In some embodiments, an application may provide multiple functions. The ADL of these multiple functions may be different during the startup phase. The ADLs of these multiple functions may also be different at the run-time. The central control apparatus 100 may hide one or more functions in one application according to a preset application hiding policy. Wherein when some of the functions in one application are hidden, the driver can still continue to use other functions in the one application that are not hidden.

For example, the central control device 100 may display a user interface of the running application a. Controls for invoking a plurality of functions provided by application a may be included on the user interface. The central control device 100 may determine whether the ADL of the multiple functional controls provided by the application a in the startup phase is higher than an ADL threshold corresponding to the current ARL. When the ADL of a function in the start-up phase is higher than the ADL threshold corresponding to the current ARL, the central control device 100 may hide the control on the user interface for invoking the function.

When the application a is providing one or more functions during operation, the central control apparatus 100 may determine whether the ADL of the one or more functions during operation is higher than an ADL threshold corresponding to the current ARL. When the ADL of a function in the running phase is higher than the ADL threshold corresponding to the current ARL, the central control apparatus 100 may stop running the program corresponding to the function in the application a. Wherein, the application A can still continue to provide other functions that the ADL in the operation stage is not higher than the ADL threshold corresponding to the current ARL.

For example, the information application may provide a function of transmitting a voice message, a function of editing and transmitting a text message, and the like. Obviously, the driver needs to pay less attention using the function of sending voice messages than the function of editing and sending text messages. When the estimated ARL is higher, for example, ARL is ARL4, the central control apparatus 100 may conceal the function of editing and transmitting a text message, and retain the function of transmitting a voice message. This can avoid the driver from being excessively distracted by using the function of editing and transmitting the text message, and it is difficult to pay sufficient attention to the current driving of the vehicle. The driver can still use the function of sending a voice message. When the estimated ARL is low, for example, ARL is ARL0, the center control device 100 may simultaneously reserve the function of transmitting a voice message, the function of editing and transmitting a text message. The driver can send voice messages or edit words to send text messages.

For another example, the navigation application may provide functions such as a voice switch navigation route function and a manual switch navigation route function. Obviously, the driver needs to pay less attention to the function of switching the navigation route using voice than to the function of switching the navigation route manually. When the estimated ARL is high, the driver is required to be highly concentrated on driving the vehicle, and the center control apparatus 100 can hide both the function of voice switching the navigation route and the function of manually switching the navigation route. This can avoid that the driver is distracted by switching the navigation route, and is hard to pay sufficient attention to the current driving of the vehicle. When the estimated ARL is a medium-sized ARL (for example, ARL is ARL 3), the central control apparatus 100 may hide the function of manually switching the navigation route, and retain the function of voice switching the navigation route, which requires the driver to pay a moderate attention to the driving of the vehicle. The driver cannot use the function of manually switching the navigation route, but can instruct the navigation application to switch the navigation route through voice. When the estimated ARL is small, the center control device 100 can retain both the function of voice switching the navigation route and the function of manually switching the navigation route, with only a small amount of attention required from the driver to the driving of the vehicle. The driver can switch the navigation route by voice and can manually switch the navigation route.

As can be seen from the above embodiments, the central control device 100 can hide each function provided by one application alone. Hiding one function in an application may not affect the use of other functions in the application. The center control apparatus 100 can detect in real time a change in how much attention the driver is required to pay attention to driving of the vehicle. When it is detected that the ADL of one function in the application may excessively attract the attention of the driver, so that the attention that the driver can pay in the driving of the vehicle cannot meet the requirements of the ARL of the current driving of the vehicle, the center control device 100 may hide the one function of the application. This can avoid the driver from using this function of the application to cause the attention to be excessively distracted, thereby improving driving safety. The driver can continue to use other functions of the application that are not hidden. The above-described method may reduce the impact of the hidden application on the driver's use of the application on the center control device 100, while achieving the goal of avoiding the driver from being excessively distracted by the application on the use of the center control device 100.

In some embodiments, the application icon management module 430 may determine whether to adjust the display position of the application icon on the central control screen according to the currently evaluated ARL and the ADL applied in the startup phase. For example, if the ARL obtained by the current evaluation is greater than the ARL obtained by the previous evaluation, the application icon management module 430 may move icons of more applications with larger ADLs to an area on the central screen far from the driver, and move icons of more applications with smaller ADLs to an area on the central screen near the driver. Alternatively, the application icon management module 430 may obtain driving information from the driving information collection module 450. Then, the application icon management module 430 may query the application icon display mode corresponding to the current driving information. The application icon management module 430 may display icons of respective applications on the central control screen according to the above-described application icon display manner.

It can be seen that in the application control method provided in the present application, the center control apparatus 100 may control the application in the center control apparatus 100 according to the driving information. The applications in the control center apparatus 100 described above may include: and controlling the display mode of the application on the central control screen, and controlling the running of the application. The display mode of the control application on the central control screen can comprise: the display position of the application on the central control screen is controlled, and/or whether the application is hidden on the central control screen is controlled. By the method, the central control device 100 can adjust the display and operation of the application on the central control screen according to the change of the driving information in real time, so that the current display of the central control device 100 and the operation of the application cannot excessively distract the driver, and the driver can pay enough attention to the driving of the vehicle. The method can effectively improve driving safety.

In some embodiments, when receiving an operation to launch an application, the central control apparatus 100 may determine whether the ADL of the application in the running phase is higher than an ADL threshold corresponding to the current ARL. When it is determined that the ADL of the application in the running stage is higher than the ADL threshold corresponding to the current ARL, the central control apparatus 100 may refuse to run the application.

Referring to fig. 8, fig. 8 illustrates a flowchart of an application control method according to an embodiment of the present application.

As shown in fig. 8, the method may include steps S811 to S819. Wherein:

s811, the application lifecycle management module 410 detects operation 1 of starting the application a.

For example, the above operation 1 may be an operation of voice instruction to launch the application a. The present application is not limited to the specific manner of operation 1 described above. The above application a is only an exemplary illustration of the present application. The application a is not limited in type.

S812, in response to operation 1, the application lifecycle management module 410 may request the application information management module 420 to obtain the ADL of the application a in the run phase.

S813, the application information management module 420 may send the ADL of the application a in the running phase to the application lifecycle management module 410.

S814, in response to operation 1, the application lifecycle management module 410 may also request the ARL assessment module 440 to obtain the current ARL.

S815, the ARL evaluation module 440 may send a driving information acquisition request to the driving information collection module 450.

S816, the driving information collecting module 450 may send driving information to the ARL assessment module 440.

S817, the ARL evaluation module 440 may perform driving attention demand level (ARL) evaluation according to the driving information, to obtain the current ARL.

The specific method of the ARL evaluation module to obtain the driving information and perform the ARL evaluation, and the specific method of the driving information collection module 450 to collect the driving information may refer to the description of the method shown in fig. 7. And will not be described in detail here.

S818, the ARL assessment module 440 may send the current ARL to the application lifecycle management module 410.

S819, the application lifecycle management module 410 may compare the ADL threshold of the application a corresponding to the current ARL to the ADL at the run stage, refuse to launch the application a if the ADL is higher than the ADL threshold, and launch the application a if the ADL is less than or equal to the ADL threshold.

The application lifecycle management module 410 can decide whether to launch application a based on the ADL of application a in the run phase, the current ARL, and the application hiding policy.

In one possible implementation, the application lifecycle management module 410 can compare the ADL of the application a at run-time to an ADL threshold corresponding to the current ARL. In the event that ADL for application a is above the ADL threshold at the run phase, the application lifecycle management module 410 may refuse to launch application a.

Alternatively, the application lifecycle management module 410 may decide whether to launch the application a according to the application hiding policy table shown in table 1. When it is determined that application a needs to be hidden according to the ADL, the current ARL, and the application hiding policy table of application a in the running stage, the application lifecycle management module 410 may refuse to start application a. Otherwise, the application lifecycle management module 410 can launch the application a.

In the case where the application a is refused to be started, the central control apparatus 100 may provide a refusal to start prompt to prompt the driver that the application a is currently unsuitable to be started. For example, the central control apparatus 100 may voice-prompt "you need to concentrate on driving the vehicle at present, and after the application a is started, you will be excessively distracted, which is unfavorable for safe driving, so that it is not preferable to start the application a". The embodiment of the application does not limit the specific mode of rejecting the start prompt.

In some embodiments, if the central control device 100 receives the operation of starting the application a again within the preset period of time after refusing to start the application a, the central control device 100 may directly respond to the operation of restarting the application a, and start the application a. That is, in the case that the user requests to start the application a multiple times, the central control apparatus 100 may meet the user's request to start the application a even if the ADL of the application a in the running stage is higher than the ADL threshold corresponding to the current ARL. This may avoid that in case the user strongly requires to launch application a, the central control device 100 refuses to launch application a affecting the user's experience of using the central control device 100.

The steps S815 to S817 are optional. In one possible implementation, upon receiving a request from the application lifecycle management module 410 to obtain an ARL, the ARL assessment module 440 may send the ARL obtained from the last assessment to the application lifecycle management module 410.

As can be seen from the method shown in fig. 8, the center control device 100 can determine whether the distraction of the driver after the application is started exceeds the maximum value of the distraction of the driver from the driving of the vehicle when receiving the operation of starting the application. In the case where it is determined that the application is excessively distracted after being started, resulting in a difficulty in the driver being put into sufficient attention on the vehicle driving, the center control device 100 may refuse to start the application. The method can avoid the situation that a driver starts an application with higher distraction degree in the operation stage in the driving process of the vehicle, so that the driver can pay enough attention to the driving of the vehicle, and the driving safety is improved.
