Description

Method for displaying user interface and vehicle-mounted terminal

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method for displaying a user interface and a vehicle-mounted terminal.

Background

With the development of technology, in-vehicle systems of touch control type have become the standard configuration of vehicles of various manufacturers in recent years. Compared with the traditional vehicle-mounted system based on physical controls, the vehicle-mounted system based on touch control can provide richer functions, such as conversation, navigation, video, music and the like. Different from a mobile interaction scene, a driving task in a vehicle-mounted scene is a main task, other tasks belong to secondary tasks, and a vehicle-mounted system is used on the premise of driving safety. However, because the touch screen of the vehicle-mounted system cannot provide tactile feedback, more visual resources of a user are occupied during driving compared with a physical control, and driving safety is affected.

Disclosure of Invention

The application provides a method for displaying a user interface and a vehicle-mounted terminal, which can realize that the vehicle-mounted terminal switches and displays different user interfaces according to the scene where a vehicle is located and the current speed of the vehicle so as to ensure the driving safety of a user.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a method of displaying a user interface, which may include: if the vehicle is in a driving state, the vehicle-mounted terminal judges whether the vehicle meets a first preset condition; the first preset condition comprises that the vehicle is in a preset scene or the current speed is greater than a first preset speed; if the vehicle meets the first preset condition, the vehicle-mounted terminal displays a first user interface, and the first user interface does not display the first function; or the first function is displayed in the first user interface in a first preset mode, and the first preset mode is used for indicating that the first function cannot be operated by a user.

The first function is a function of occupying more visual resources or cognitive resources of the user. Illustratively, the first function includes any one or more of: the system comprises an entertainment function, an information function, a dialing function in a call function, a contact searching function in the call function, an address searching function in a navigation function, a song searching function in a music function and a weather inquiry function in a weather function.

Therefore, by setting the preset scene and the first preset speed, the vehicle-mounted terminal can judge whether the current vehicle is in the preset scene or whether the current vehicle speed is greater than the first preset speed in the vehicle running process, and further determine whether the current vehicle state requires the user to pay high attention to vehicle driving. When the user needs to pay high attention to vehicle driving, the touch screen of the vehicle-mounted terminal does not display or display but does not allow the user to use a function that part of the touch screen occupies more visual resources or cognitive resources of the user, so that the user pays high attention to vehicle driving, and the driving safety of the user is ensured.

In a possible implementation manner, the first user interface displays the second function in a second preset manner, and the second preset manner is used for indicating that the user is allowed to operate the second function.

The second function is a function which occupies less visual resources or cognitive resources of the user. Illustratively, the second function includes any one or more of: a recent contact function of the call function, a recommended address function of the navigation function, a recent play list function in the music function, and a local real-time weather function in the weather function.

In one possible implementation manner, after the vehicle-mounted terminal displays the first user interface, the method further includes: and if the vehicle-mounted terminal detects the first operation of the user on the first user interface, the vehicle-mounted terminal displays a third user interface. The third user interface displays only the first function in a first preset mode. The first operation is any one of the following operations of a user on a touch screen of the vehicle-mounted terminal: click operation, sliding operation, preset pressing operation and preset gesture operation.

Therefore, when the current interface does not display some functions or displays all functions but some functions cannot be operated, the vehicle-mounted terminal can intensively display all functions occupying high visual resources and cognitive resources of the user on one interface through some simple operations, so that the user can quickly lock the functions which are required to be operated but hidden or not allowed to be operated, and the dispersed attention of the user for searching the functions is reduced.

In one possible implementation, the preset scenario includes any one or several of the following: the vehicle runs on a section with dense pedestrian flow, the vehicle runs on a section with high danger, the vehicle runs at night, the vehicle runs under severe weather conditions, and the vehicle runs on a section with speed limit.

In one possible implementation, the determining whether the vehicle is in a preset scene includes: the vehicle-mounted terminal judges whether the vehicle runs on the section with dense people flow according to at least one item of data: a vehicle running state, an image of a vehicle surroundings, a vehicle running route; and/or judging whether the vehicle runs on the high-risk road section or not by the vehicle-mounted terminal according to at least one of the following data: a vehicle travel route, a vehicle travel state, an image of a vehicle surroundings; and/or judging whether the vehicle runs at night by the vehicle-mounted terminal according to at least one of the following data: ambient light conditions of the vehicle, images of the vehicle's surroundings, real time; and/or the vehicle-mounted terminal judges whether the vehicle runs under the severe weather condition according to at least one of the following data: ambient light conditions of the vehicle, images of the surrounding environment, data of weather software; and/or judging whether the vehicle runs on the speed-limited road section or not by the vehicle-mounted terminal according to at least one of the following data: an image of the vehicle surroundings, current road information.

In a possible implementation manner, if the vehicle-mounted terminal detects a second operation of the user, the vehicle-mounted terminal starts a voice control mode; the second operation is to operate a first preset button or an icon of the first function, and is used for starting the first function; the voice control mode is used for voice interaction between the user and the vehicle-mounted terminal.

Therefore, the user can use some functions occupying more visual resources and cognitive resources of the user through the voice control mode, and the voice control operation does not occupy the excessive attention of the user, so that the use requirement of the user can be met on the premise of ensuring the driving safety of the user, and the user experience is improved.

In a possible implementation manner, the vehicle-mounted terminal starts the voice control mode, and specifically includes: the vehicle-mounted terminal starts a voice interaction function; the vehicle-mounted terminal prompts the user to operate the first function through the third operation according to the voice interaction function, and informs the user of an operation method of the third operation; wherein the third operation is an operation in a voice interaction form.

In one possible implementation manner, the first preset condition further includes: the vehicle is in a preset scene, and the current speed is greater than a second preset speed; and the second preset speed is the minimum speed limit corresponding to the preset scene.

Therefore, the speed limit of the preset scene is set, the first function does not need to be hidden or forbidden when the vehicle is in the preset scene and the current vehicle speed is slow, and the user experience is further improved on the premise of ensuring the driving safety of the user.

In a possible implementation manner, if it is determined that the vehicle does not meet the first preset condition, the vehicle-mounted terminal displays a second user interface, the second user interface displays the first function and the second function in a second preset manner, and the second preset manner is used for indicating that the user is allowed to operate the first function and the second function.

In a second aspect, an embodiment of the present application provides an in-vehicle terminal, where the electronic device may be an apparatus for implementing the method in the first aspect. The electronic device may include: one or more processors; a memory having instructions stored therein; the touch screen is used for detecting touch operation and displaying an interface; the instructions, when executed by the one or more processors, cause the electronic device to perform the method of displaying a user interface of the first aspect.

In a third aspect, the present application provides a vehicle-mounted terminal having a function of implementing the method for displaying a user interface of any one of the first aspect. The function can be realized by hardware, and can also be realized by executing corresponding software by hardware. The hardware or software includes one or more modules corresponding to the functions described above.

In a fourth aspect, an embodiment of the present application provides a computer storage medium, which includes computer instructions, and when the computer instructions are executed on a vehicle-mounted terminal, the vehicle-mounted terminal is caused to perform the method described in the first aspect and any one of the possible implementation manners.

In a fifth aspect, embodiments of the present application provide a computer program product, which when run on a computer, causes the computer to perform the method as described in the first aspect and any one of the possible implementations thereof.

The modem processor may include a modulator and a demodulator. The modulator is used for modulating a low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then passes the demodulated low frequency baseband signal to a baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor. The application processor outputs a sound signal through an audio device (not limited to the speaker 170A, the receiver 170B, etc.) or displays an image or video through the display screen 194.

The ISP is used to process the data fed back by the camera 193. For example, when a photo is taken, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal.

The speaker 170A, also called a "horn", is used to convert the audio electrical signal into an acoustic signal. The electronic apparatus 100 can listen to music through the speaker 170A or listen to a handsfree call.

The receiver 170B, also called "earpiece", is used to convert the electrical audio signal into an acoustic signal. When the electronic apparatus 100 receives a call or voice information, it can receive voice by placing the receiver 170B close to the ear of the person.

The microphone 170C, also referred to as a "microphone," is used to convert sound signals into electrical signals.

In some embodiments of the present application, the electronic device 200 may capture an image of the surrounding environment of the vehicle through the camera 270, so that the electronic device 200 or the electronic device 100 performs image analysis to determine the current scene where the user is located, for example: whether the vehicle runs on a high-risk road section, and the like.

The functions of the speaker 240, the microphone 250, the display screen 260 and the like can refer to the related descriptions in the electronic device 100, and are not described herein.

It is to be understood that the illustrated structure of the embodiment of the present invention does not specifically limit the electronic device 200. In other embodiments of the present application, the electronic device 200 may include more or fewer components than shown, or combine certain components, or split certain components, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The following describes the technical solution provided in the embodiment in detail, taking the example that the electronic device 100 is a mobile phone and the electronic device 200 is a car machine.

In the prior art, a touch control type vehicle-mounted system (vehicle machine) has gradually become a standard configuration of vehicles of various manufacturers, but because a touch screen of the vehicle-mounted system cannot provide tactile feedback, more visual resources of a user can be occupied during driving, so that the user cannot concentrate on driving, and driving safety is affected. In addition, when the user drives, the user can also choose to connect the mobile phone to the car machine, and the car machine interacts with the functions of the mobile phone, so that the use of the vehicle-mounted system is further enriched. During the driving of the vehicle, the user may pay attention to the display screen of the vehicle-mounted system to process the notification message received by the mobile phone or use the richer entertainment functions of the mobile phone. However, when the user drives the vehicle at a high speed or is in some specific scenes, such as a situation where the user drives the vehicle in a heavily pedestrian-laden road section, a situation where the user drives the vehicle through a high-risk road section, a situation where the user drives the vehicle at night, a situation where the user drives the vehicle in bad weather, or a situation where the user drives the vehicle in a speed-limited road section, the user should use more effort for focusing on the driving without being distracted. In other words, in some cases, a user interface capable of reducing visual resources and cognitive resources occupied by a vehicle display screen should be provided, so as to ensure driving safety.

Therefore, the embodiment of the application provides a method for displaying a user interface, after a vehicle machine starts to work, various scenes where a vehicle is located can be automatically identified, different user interfaces are displayed based on different scenes, and when the scene where the vehicle is located changes, the corresponding user interface can be displayed according to the changed scene. Wherein the displayed user interface may include a first user interface and a second user interface. The first user interface is a user interface which does not display part of functions or displays but cannot operate part of functions, and the second user interface is a user interface which displays all functions. The functions include some functions and some operations of some functions, wherein some functions may be presented in the form of mobile phone software (APP).

For example: the touch screen of the car machine may display a second user interface when it is recognized that the user is not driving.

For another example: recognizing that the user is driving but in some scenes where the user may not be paying too much attention or in some scenes where the user is allowed to perform some other operation with little visual or cognitive resources, i.e., the user is not paying a high degree of attention, the touch screen of the in-vehicle device may display a second user interface.

Another example is: and when the situation that the user is driving and is in a scene needing high concentration is recognized, the car machine touch screen displays the first user interface.

The method for displaying the user interface in the embodiment of the application can be pre-configured in the vehicle-mounted terminal, so that all the vehicle-mounted terminals display the user interface by adopting the method; or the vehicle-mounted terminal does not adopt the method for displaying the user interface after the user is set according to the selection of the user.

The specific scene requiring high concentration of attention includes, for example, when the user drives a vehicle to travel at a high speed (a first preset speed may be determined according to vehicle performance, and it is determined that the vehicle is traveling at a high speed when a real-time vehicle speed is greater than the first preset speed), when the user drives the vehicle to travel at a road section with dense people flow (e.g., a business center, a tourist attraction, a school road section, etc.), when the user drives the vehicle to travel through a high-risk road section (e.g., a continuous turn, an expressway, a tunnel, etc.), when the user drives the vehicle at night (e.g., may be determined according to a sunset time, determined according to illumination intensity, etc.), when the user drives the vehicle in severe weather (e.g., dense fog, ice and snow weather, thunderstorm weather, etc.), and when the user drives the vehicle at a speed-limited road section (e.g., a.

Sometimes, the car machine cannot accurately identify the scene where the user is located, and under the condition that the mobile phone is connected to the car machine, the recognition results of the mobile phone and the car machine can be combined, so that the scene where the user is located can be identified more accurately. For example, when it is recognized that the user is driving but not in a scene requiring high concentration, the touch screen of the car machine may display a user interface including all functions. And when the situation that the user needs to be highly concentrated is identified, the touch screen of the car machine displays a hidden or unallowed user interface for operating partial functions and/or after operation.

In some embodiments, it may be that the user starts to be in a scene that does not require high attention, and operates some functions on the second user interface of the touch screen of the in-vehicle device, and during the operation, the user enters the scene that requires high attention, and at this time, the in-vehicle device may immediately interrupt the current operation and switch to display the first user interface, so as to ensure driving safety. Or, the user interface can be switched after the user completes the current operation, so that the experience of the user can be guaranteed. In this regard, the embodiments of the present application are not particularly limited.

As shown in fig. 4, a flowchart of a method for switching a user interface provided in the embodiment of the present application is specifically as follows:

and S401, starting the vehicle machine to work.

Specifically, after the user starts the vehicle to start the driving mode, the vehicle machine starts to display the user interface of the touch screen, and at this time, the vehicle machine is judged to start to work. Generally, the user interface at this time is a second user interface (see fig. 6) that is displayed by default and contains all functions.

It should be noted that, in the embodiment of the present application, whether the mobile phone is connected to the car machine is not limited, that is, the mobile phone may be connected to the car machine or not. The step only considers whether the car machine starts to work or not, and does not need to consider the connection condition of the mobile phone and the car machine.

And under the condition that the mobile phone is not connected to the vehicle machine, the vehicle machine identifies the scene. Under the condition that the mobile phone is connected to the car machine, data of the mobile phone can be synchronized with the car machine, the car machine is combined with the data collected by the mobile phone to identify the scene where the user is located, and then the user interface corresponding to the scene is displayed more accurately. In other words, the car machine may undertake all or part of the data processing work of the mobile phone, and the division of work between the car machine and the mobile phone is not limited in the embodiment of the present application.

The following steps are explained by taking an example that the car machine is responsible for judging the user state and scene and determining the user interface displayed by the car machine touch screen.

S402, the vehicle machine determines whether the vehicle is in a driving state. If the vehicle is not in a driving state (i.e., is in an undriven state), step S403 is executed. If the vehicle is in the driving state, step S404 is executed.

In a possible implementation manner, information such as the speed per hour of the vehicle measured by the vehicle-mounted device may be obtained, and whether the vehicle is in a traveling state or not may be determined, so as to determine whether the vehicle is in a driving state or not. The real-time position of the vehicle machine can also be determined through a Global Positioning System (GPS) of the vehicle machine, and the moving speed of the vehicle machine can be calculated according to the real-time position. And then, judging whether the moving speed of the vehicle machine is greater than a threshold value. If the moving speed of the vehicle machine is greater than the threshold value, the vehicle can be considered to be in a driving state. If the moving speed of the vehicle machine is not greater than the threshold value, the vehicle can be considered not to be in a driving state.

Optionally, in a case where the mobile phone is connected to the car machine, the car machine may also obtain data of the mobile phone, and obtain a moving speed of the mobile phone through a sensor (for example, an acceleration sensor) provided in the mobile phone, so as to determine whether the vehicle is in a driven state.

And S403, displaying a second user interface on the touch screen of the car machine.

Specifically, when it is determined that the vehicle is not in a driving state, or when the user using the vehicle is not paying attention to the vehicle, the touch screen of the vehicle is available if the user can conveniently operate the vehicle. And displaying the first function and the second function in a second preset mode in the second user interface, wherein the second preset mode is used for indicating that the user is allowed to operate the first function and the second function. The first function and the second function form all functions displayed on the touch screen of the car machine, namely, the second user interface displays all functions for the user to select and use.

As shown in fig. 6, a user interface of a touch-controlled car machine is exemplarily shown, and the user interface includes a main menu 601 displayed on the left side and a display interface 602 displayed on the right side. The main menu 601 displays main functions included in the car machine, and the display content in the display interface 602 corresponds to each function in the left main menu 601 and displays different user interfaces respectively. Five functions of home page, navigation, talk, music and car control are exemplarily given in a main menu 601 of the user interface shown in fig. 6. Generally, the touch screen displays all the commonly used functions on the home interface (i.e. the display interface 602 displayed correspondingly after the "home" function on the main menu 601 is selected), as shown in fig. 6, the user interface displayed correspondingly on the display interface 602 after the "home" function on the main menu 601 is selected is exemplarily shown, that is, the home interface includes six commonly used functions of map, WeChat, contact, telephone, entertainment and weather.

It should be understood that the car machine should further include other main or common application functions that can be displayed on the car machine touch screen, and based on the touch operation, the current home page interface can be switched to display more common functions, which may be referred to in the prior art, and this embodiment of the present application is not specifically described.

And then, the user can click corresponding functions step by step to enter the submenu according to the requirements, so as to realize the final function. For example, when a user wants to perform a call operation using the car phone, the user can touch a phone icon to enter a call interface, and then can perform a dialing operation or a phone query operation to perform a phone call. Or as shown in fig. 7, the user clicks the call function on the interface of the main menu 601 on the left side of the screen, and the display interface 602 corresponds to a call interface, in which operations such as dialing operation, contact search, and browsing of the recent contact list (this interface is not shown in fig. 7, it is understood that this function interface can be accessed through relevant operations) can be provided to the user.

S404, the vehicle machine determines that the vehicle is in a preset scene or the current vehicle speed is greater than a first preset speed. If the vehicle-mounted device determines that the vehicle is in the preset scene or the current vehicle speed is greater than the first preset speed, step S405 is executed, and if the vehicle-mounted device determines that the vehicle is not in the preset scene and the current vehicle speed is less than or equal to the first preset speed, step S403 is executed.

Specifically, it may be determined that the vehicle is in a preset scene or the current vehicle speed is greater than a first preset speed as the first preset condition. And then judging that the vehicle machine touch screen displays a first user interface when the vehicle meets a first preset condition.

The preset scene may be, for example: when a user drives a vehicle to run on a road section with dense people flow (such as a business center, a tourist attraction, a school road section and the like), when the user drives the vehicle to pass through a high-risk road section (such as a continuous turn, an expressway, a tunnel and the like), when the user drives the vehicle to run at night (such as determined according to the time of falling mountain of the sun, determined according to the illumination intensity and the like), when the user drives the vehicle in severe weather (such as dense fog, ice and snow weather, thunderstorm weather and the like), when the user drives the vehicle on a speed-limiting road section (such as a downhill road section, a village section, a road intersection and the like) and the like.

Whether the current scene is the preset scene or not can be a conclusion obtained by analyzing and judging the current scene by the vehicle-mounted device according to the sensing data or other manners, and specific exemplary five preset scene judging methods are provided, which are described in detail below.

Presetting a first scene: the vehicle is in a section with dense people flow.

When judging whether the user drives the vehicle to travel on a road section with dense people flow, the data can be analyzed through sensor data in the vehicle and/or the mobile phone. The vehicle-mounted device judges whether the vehicle is in a crowded road section or not at least according to at least one of the following data: a running state of the vehicle, an image of the surroundings of the vehicle or a running route. For example: whether the vehicle is located on a crowded section of people can be determined according to the speed per hour of the vehicle. It is also possible to determine whether the vehicle is in a crowded place such as a business center, based on the position of the vehicle.

Optionally, the vehicle should have a capability of acquiring the vehicle speed in real time, and the vehicle-mounted device may acquire a change of the vehicle speed within a period of time, and if the vehicle speed is repeatedly changed within a preset time period and the vehicle speeds are small, that is, the vehicle is repeatedly braked within the preset time period, it may be determined that the vehicle is located in the road section with dense pedestrian flow, so that the vehicle cannot smoothly run.

Optionally, the navigation software includes road information of each road segment, for example: a certain business center road segment, a certain tourist attraction, a school road segment, etc., and generally, the people flow on these road segments is relatively dense. Therefore, the current position of the vehicle is determined according to the vehicle machine and/or the mobile phone, and whether the vehicle is in the road section with dense people flow is determined according to the current position and the road information of the position in the navigation software.

Optionally, the environment outside the vehicle can be identified by adopting an image analysis technology according to the image of the surrounding environment of the vehicle shot by the camera through the camera in the vehicle or the camera connected with the vehicle, and then whether the vehicle is in a road section with dense people flow is determined. In this case, a numerical value may be preset, for example, when the number of people around the vehicle exceeds 10, it is determined that the vehicle is in a section with dense people flow.

Presetting a scene II: vehicles are passing through high-risk road sections.

When judging whether the user drives the vehicle to pass through the high-risk road section, the data can be analyzed through sensor data in the vehicle and/or the mobile phone. Wherein, the vehicle machine judges whether the vehicle is in the high-risk road section according to at least one item of following data at least: a running route of the vehicle, a running state, or an image of the environment around the vehicle. For example: whether the vehicle is continuously turning may be determined according to the traveling route of the vehicle. It is also possible to determine whether the vehicle is located on the expressway based on the speed per hour of the vehicle. It is also possible to determine whether the vehicle is running on a wet road surface or the like, based on the running route and the running speed of the vehicle. The light around the vehicle can be judged through the light sensor, and whether the vehicle is located in a tunnel or not can be further determined.

Optionally, the environment outside the vehicle can be identified by adopting an image analysis technology according to the image of the surrounding environment of the vehicle shot by the camera or the camera connected with the vehicle, so as to determine whether the vehicle is in the high-risk road section.

Optionally, since the navigation software includes road condition data (e.g., sharp turns, tunnels, etc.) of each road segment, the current position of the vehicle may be determined according to the mobile phone or the vehicle, and whether the vehicle is in the high-risk road segment may be determined according to the current position and the road condition data of the position in the navigation software.

Presetting a scene three: the vehicle is in a night driving state.

When judging whether the user drives the vehicle at night, the vehicle can be analyzed through sensor data in the vehicle and/or the mobile phone. Wherein, the vehicle machine judges whether the vehicle is in a night driving state according to at least one item of data: ambient light conditions in which the vehicle is located, images of the vehicle surroundings, or real time. For example: and when the illumination intensity is lower than the threshold value and the duration exceeds the threshold value, judging that the user is in a night driving state. Or, the user drives the vehicle to run in the period from one hour after the sun falls to one hour before the sun rises, and then the user is determined to be in the night running state.

Optionally, an image analysis technology may be adopted according to an image of the surrounding environment captured by a camera of the vehicle and/or the mobile phone, so as to identify the illumination intensity of the environment where the vehicle is located, and determine whether the user is in a night driving state.

Optionally, light around the vehicle can be judged according to a light sensor of the vehicle machine, and light duration can be further combined, so that whether the user is in a night driving state or not can be more accurately determined.

Optionally, the starting time of night driving can be judged after the sun falling time according to the current time period and the position coordinate, and the ending time of night driving can be judged before the rising time of the sun. For example, if the rising time of the sun is 7:00 and the falling time of the sun is 18:00 in the current season of a certain place, the night driving time period can be defined as 19: 00-6: 00 of the next day, and the user drives at night in the time period.

Presetting a scene four: the current weather conditions are severe.

When judging whether the user drives the vehicle in severe weather, the data can be analyzed through the sensor data in the mobile phone and/or the vehicle machine. Wherein, the vehicle machine judges whether the vehicle is driven under the bad weather condition according to at least one item of data below: ambient light conditions in which the vehicle is located, images of the surrounding environment or data of weather software. For example: the environment around the vehicle, for example, the vehicle is in heavy fog, darkness, can be determined from a light sensor or the like in the vehicle. Whether the vehicle is in thunderstorm weather or not can be determined according to a rainfall sensor in the vehicle.

Optionally, the vehicle may further include a camera connected in the vehicle, and the environment outside the vehicle is identified by using an image analysis technology according to the image of the surrounding environment of the vehicle captured by the camera, so as to determine whether the vehicle is in the above-mentioned bad weather.

Optionally, the current weather condition may also be obtained through the weather application software, so as to determine whether the vehicle is in the above severe weather.

Presetting a scene five: the vehicle is in the speed-limiting road section.

When judging whether the user is in the speed-limiting road section to drive the vehicle, the vehicle machine at least judges according to at least one of the following data: an image of the vehicle surroundings, current road information. For example, the current road information can be determined through navigation software in a vehicle and/or a mobile phone, and then whether the user is in the speed-limiting road section is determined. General special road sections, such as: the vehicle speed limit is carried out on the downhill road section, the village road section, the road intersection and the like, so that the driving safety is ensured, the navigation software contains special road section information, and the vehicle machine can confirm whether the user is in the speed-limit road section according to the driving position of the user vehicle.

Optionally, the vehicle can be determined whether to be on the speed-limiting road section by using an image analysis technology according to the speed-limiting signs arranged on the road sections around the vehicle shot by the camera through the camera connected in the vehicle.

The vehicle machine can obtain corresponding data according to the method to further judge whether the vehicle is in a preset scene or in which preset scene or multiple preset scenes, and further judge whether the user needs to concentrate on the attention at the moment.

The vehicle speed is a large factor affecting the attention of the user, and when the vehicle speed is high, the user must concentrate on driving the vehicle, so that the first preset speed is set for judging whether the current vehicle is in a high-speed driving state.

The first preset speed is a threshold value determined according to vehicle performance or directly preset. When judging whether the user drives the vehicle to run at a high speed, the vehicle machine can acquire information such as the measured speed per hour of the vehicle in real time and compare the real-time speed with the first preset speed so as to determine whether the user drives the vehicle to run at a high speed. For example, the first preset speed may be set to 60km/h, and when the speed per hour of the user driving the vehicle is greater than 60km/h, the user is considered to be driving the vehicle at a high speed. Or, the performance of the vehicle used by the current user is better, and the first preset speed can be set to be 65 km/h; alternatively, the user currently using the vehicle may be a novice driver or the user is older, and a lower first preset speed, such as 50km/h, may be set. Of course, the first preset speed may also be set according to other situations, and this embodiment of the present application is not particularly limited.

Optionally, the real-time position of the vehicle machine can be determined through a GPS of the vehicle machine, and the moving speed of the vehicle machine is calculated according to the real-time position. And then, judging whether the moving speed of the vehicle machine is greater than a first preset speed or not. If the moving speed of the vehicle machine is greater than the first preset speed limit, the user can be considered to be driving the vehicle at a high speed. If the moving speed of the vehicle machine is not greater than the first preset speed, the user can be considered not to drive the vehicle to run at a high speed.

Optionally, in a case where the mobile phone is connected to the car machine, the car machine may also obtain data of the mobile phone, and obtain a moving speed of the mobile phone through a sensor (for example, an acceleration sensor) arranged in the mobile phone, so as to determine whether the user is driving the vehicle at a high speed.

It should be noted that, in an implementation manner of step S404, the car machine first determines whether the vehicle driven by the user is in a preset scene. If the vehicle is in the preset scene, step S405 may be directly executed, that is, when the vehicle is in the preset scene, the user should focus on driving the vehicle and cannot operate the vehicle machine with too much distraction. If the vehicle speed is not in the preset scene, whether the current vehicle speed is greater than the first preset speed or not, namely whether the vehicle is in a high-speed driving state or not, is further judged. If the current vehicle speed is greater than the first preset speed, step S405 is performed such that the user is highly focused on the driving of the vehicle when the vehicle is in a high speed driving state even though the vehicle is not in the preset scene. If the current vehicle speed is less than or equal to the first preset speed, step S403 is executed, that is, only when the vehicle is not in the preset scene and the current vehicle is not in the high-speed driving state, the vehicle-mounted device may display user interfaces with all functions for the user to use.

In another implementation manner of step S404, the vehicle machine first determines whether the current vehicle speed is greater than a first preset speed. If the current vehicle speed is greater than the first preset speed, that is, the current vehicle is in a high-speed driving state, step S405 is directly performed, that is, when the vehicle is in the high-speed driving state, the user must pay high attention to the driving of the vehicle. And if the current vehicle speed is less than or equal to the first preset speed, further judging whether the vehicle is in a preset scene. As described above, if it is in the preset scene, step S405 is performed. If the vehicle is not in the preset scene, that is, when the vehicle is not in the preset scene and the current vehicle is not in the high-speed driving state, step S403 is executed.

S405, displaying the first user interface by the touch screen of the car machine.

Specifically, the first user interface does not display the first function; or the first function is displayed in the first user interface in a first preset mode, and the first preset mode is used for indicating that the first function cannot be operated by a user. And displaying a second function in a second preset mode in the first user interface, wherein the second preset mode is used for indicating that the user is allowed to operate the second function. The first function is a function which occupies more visual resources and cognitive resources of the user during operation, the second function is a function other than the first function, and the second function occupies less visual resources or cognitive resources of the user. Further, functions in the embodiments of the present application refer to certain functions or certain operations of certain functions. The function can be presented in the form of an APP installed on the electronic device, and the operation can be an operation option provided by the APP installed on the electronic device.

The function of occupying more visual resources and cognitive resources of the user refers to an operation which can be performed after the user further thinks and needs visual participation. Such as: when dialing, a user needs to recall a number to be dialed in the mind and the sea, and needs to click corresponding numbers on the touch screen in sequence by using visual resources and ensure correct clicking, so that correct dialing operation can be realized, and a large amount of visual resources and cognitive resources of the user are occupied. For another example: when the navigation function is used, a user may search for a place, the place must be input on the touch screen by using visual resources, and to ensure the accuracy of the input, the navigation function may recommend several routes in some cases, and the user needs to further think to confirm the final route, so that more visual resources and cognitive resources of the user must be occupied. The occupation of visual resources and cognitive resources can divert a great deal of attention of the user, so that the user cannot concentrate on driving the vehicle. Therefore, when the vehicle is in a preset scene or the vehicle speed is fast, the vehicle must be driven with attention to ensure driving safety, and the vehicle machine needs to hide the first functions occupying more visual resources and cognitive resources of the user or enable the user to be incapable of operating the first functions so as to ensure driving safety.

Then, the first function includes any one or more of: the system comprises an entertainment function, an information function, a dialing function in a call function, a contact searching function in the call function, an address searching function in a navigation function, a song searching function in a music function and a weather inquiry function in a weather function. The second function comprises any one or more of: a recent contact function of the call function, a recommended address function of the navigation function, a recent play list function in the music function, and a local real-time weather function in the weather function.

It should be noted that the first function and the second function are only exemplary, and the first function and the second function may also include other functions. In addition, the division of the first function and the second function may be preconfigured by a manufacturer according to experience, or may be determined by the vehicle machine according to a use condition of a user, which is not specifically limited in this embodiment of the application.

In one possible implementation, two first user interfaces are shown by way of example in FIG. 8. In the 6 corresponding common functions on the display interface 602 after the user selects the "home page" function on the main menu 601, the wechat function and the entertainment function may occupy more visual resources or cognitive resources of the user when in use, for example, when the wechat information is replied, the user needs to concentrate the vision on the touch screen to read or type, and further cannot pay attention to the driving condition ahead, and the occurrence proportion of danger is increased in a preset scene or when the vehicle speed is fast. The WeChat function and the entertainment function are determined as the first function, and the map function, the contact function, the telephone function, and the weather function are determined as the second function. Therefore, as shown in (a) of fig. 8, the first user interface does not display the first function, but only displays the second function. Namely, the first function is hidden at this time, so that the user cannot operate the first function but can operate the second function. Alternatively, as shown in fig. 8 (b), the first function is made inoperable by the user in a manner of a draw fork on the main screen, but the second function allowing the user to operate is normally displayed. Of course, besides the way of drawing a fork, the first function cannot be operated by the user by adopting the way of graying the icon (the function cannot be used after clicking), which is not specifically limited in the embodiment of the present application.

In a possible implementation, as shown in fig. 9, a first user interface is further provided, in which a first function is a partial operation of a call function. Some functions on the touch screen of the car machine occupy more visual resources or cognitive resources of a user, but the functions are frequently used or necessary for the user, and the functions cannot be completely disabled (hidden or not allowed to operate) by adopting the method. Accordingly, operation of such functions that occupy more of the user's visual or cognitive resources may be disabled to focus the user on vehicle driving. For example, the call function is an essential function, and the car device cannot directly and completely disable the call function in order to avoid missing important contact messages, but can disable partial operations of the call function in order to ensure driving safety of the user. Referring to fig. 9, compared to the call interface shown in fig. 7, in the call interface shown in fig. 9, only the call record interface is reserved, and the dialing and contact searching functions are not displayed, so that the user can dial back the call to the contact who has recently called by clicking once. The communication contact is realized without occupying higher visual resources or cognitive resources. For another example, the navigation function is an essential function for the user to drive the vehicle, and cannot be prohibited from being used comprehensively. Therefore, the car machine only provides address recommendation on the navigation interface, and a user obtains an optimal driving route by clicking a corresponding address, so that the navigation function is realized. And the address search through the touch screen is forbidden, so that the driving safety of the user is ensured.

Therefore, the method for displaying the user interface provided by the application can be used for judging whether the current vehicle is in the preset scene or whether the current vehicle speed is greater than the first preset speed by the vehicle machine through setting the preset scene and the first preset speed in the vehicle running process, and if the current vehicle is determined to be in the preset scene or the current vehicle speed is greater than the first preset speed, the vehicle machine determines to display the first user interface. The method and the device have the advantages that the situation that in the prior art, all functions are displayed on the user interface constantly, so that the user needs to operate the functions which occupy high visual resources and cognitive resources in a distracted mode when needing to drive the vehicle with high concentration, and driving is not safe is caused.

In a possible implementation manner, the car machine may provide an operation entry for the user at the first user interface, so that the user may operate the first function in other manners that occupy less visual resources or cognitive resources of the user. For example, a first preset button may be provided to provide the operation entry for the user, and the first preset button is used to guide the user to perform a related operation in combination with a voice function of the car or mobile phone, so as to improve user experience. Illustratively, referring to fig. 10, a first preset button is added on the basis of the user interface shown in (b) of fig. 8. Referring to fig. 11, a first preset button is added to the user interface shown in fig. 9. The first preset button provides the user with access to such high-resource-occupation-type (occupying more visual and cognitive resources of the user) functions or operations, so that the user can use the disabled functions or operations. The user can operate the first operation preset button through clicking, dragging or other types of actions, when the screen detects that the user operates the first operation preset button, the user indicates that the user wants to use the high-resource occupation type functions or operations, and at this time, the car machine executes step S406, namely, the user can be guided to operate the functions in a voice broadcast mode.

It should be noted that the first preset button may be set on the first user interface by the car machine, and may also be set and displayed on the second user interface. Therefore, when the car machine touch screen displays all functions, other modes which occupy less visual resources or cognitive resources of the user can be provided for the user to operate the car machine touch screen. And the first preset button may be configured as a floating button for more convenient user operation. The embodiment of the present application is not particularly limited to the user interface and the display form displayed by the first preset button.

Optionally, the first preset button may not be set, and the first function displayed in the first preset manner may be combined with a voice function of the car or mobile phone to guide the user to perform a related operation. That is, the voice control mode may be entered when the first user interface detects user manipulation of the first function icon. Since the first user interface may be a user interface that does not display the first function as shown in (a) of fig. 8, or a user interface that displays the first function in a first preset manner and displays the second function in a second preset manner as shown in (b) of fig. 8. At this time, the user cannot directly lock the first function or needs to select a desired first function from all the functions, and the selection of the first function takes a certain attention of the user. Therefore, the car-mounted device touch screen may detect a first operation of the user at the first user interface, and when the first operation of the user is detected, as shown in fig. 12, the car-mounted device touch screen displays a third user interface in which all first functions are displayed in a first preset manner, and only the first functions are displayed at the current third user interface so that the user may quickly lock the required functions. The first operation is any one of the following double-click or sliding operations and the like of a user on a touch screen of the car machine: click operation, sliding operation, preset pressing gesture operation and preset gestures. The clicking operation can be single-clicking, double-clicking or multi-time continuous clicking operation of the user at the non-functional icon display area of the first user interface. The sliding operation is a longitudinal or oblique sliding operation distinguished from a mode of switching a display screen by a touch screen of an existing car machine, or a multi-finger sliding operation, and the like. The preset pressing gesture operation is a pressing gesture set by a user according to a use habit, such as single-finger or multi-finger pressing. The preset gesture operation is a gesture set by a user according to a use habit, such as "drawing a circle" and the like. The first operation is not particularly limited in the embodiment of the present application.

The detection of the second operation of the detection user on the first preset button or the first function icon is added to the touch screen of the car machine, so that the car machine can meet the requirement that the user uses certain functions or operations which are not allowed to be used in the current vehicle state, and the user experience is improved on the premise of ensuring safe driving.

S406, entering a voice control mode.

Specifically, after the car machine touch screen detects a second operation of the user, the car machine starts a voice interaction function. The second operation is to operate a first preset button or an icon of the first function, and is used for starting the first function. The voice control mode is used for voice interaction between a user and the vehicle machine. The car machine prompts the user to operate the first function through the third operation according to the voice interaction function, and informs the user of an operation method of the third operation. Wherein the third operation is an operation in a voice interaction form.

For example, after the user operates a first preset button or a first function icon on the first user interface shown in fig. 10, the user enters a voice control mode, and the user interface shown in fig. 13 or fig. 15 is displayed. For another example, after the user operates the first function icon on the third user interface shown in fig. 12, the voice control mode is entered, and the user interface shown in fig. 13 or fig. 15 is displayed. For another example, after the user operates the first preset button on the user interface shown in fig. 11, the user enters the voice control mode, and the user interface shown in fig. 14 is displayed.

Alternatively, when the first function is some functions, as shown in fig. 13, the first function is operated by a voice control mode. After the user selects the "home" function in the menu bar 601, the user operates the first preset button on the user interface correspondingly displayed on the display interface 602 to enter the voice control mode, and at this time, the in-vehicle device can perform voice broadcast of "risk exists in current operation" to prompt the user that the driving risk can be improved by the functions of this type. The car machine continues to voice-report "ask for what help is needed" to ask the user what operation needs to be performed at this time. The user may answer the action that he wants to perform, for example, as shown in fig. 13, the user may answer "view the latest WeChat message" by looking at the WeChat (information) message. Because the car machine can be without the user participation operation just can be with the pronunciation of turning into the characters and report, and then can realize this operation, so judge that the WeChat function that current user wanted to use can realize through speech control, judge that the user can use the WeChat function promptly. Therefore, the car machine can play the 'opened WeChat' through voice broadcasting. And then, playing the latest WeChat message 'mom message' when the user wants to check. At this time, the user can directly control the car machine through voice to execute the desired operation, for example, the car machine is used for information reply, and the user can directly command the car machine to reply for half an hour through voice. Finally, the car machine receives the command and broadcasts the reply content ' reply ' for half an hour ' in a voice mode, so that the user confirms the final result. If not, the user needs the voice control car machine to input the related content again. For example, the user may command the car machine to "current message is wrong", "reply" for half an hour ", so that the car machine can perform correct operation conveniently. If so, the user does not have to perform any more operations. Alternatively, the user may directly enter the voice control mode by operating the icon of the first function through the user interface shown in fig. 10 or 12. Through the operation, the user can operate the first function through other modes which occupy less visual resources or cognitive resources of the user, and the driving safety of the user is ensured while the user experience is improved.

Alternatively, when the first function is some operations of some functions, as shown in fig. 14, the first function is operated by a voice control mode. When the user finds that there is no contact, such as "mom", in the latest call record in the call interface shown in fig. 11, the user cannot dial, so that the user cannot make a call. The user can operate the first preset button in fig. 11 to present a user interface that can be voice-controlled as shown in fig. 14. At this moment, the car machine can carry out voice broadcast "ask for what help needs". The user answers the operation currently desired, such as "call mom". The car machine judges whether the operation which the current user wants to carry out can be finished through voice operation. The operation of dialing the phone can be directly finished by the car machine without manual control of a user. Therefore, the car machine can perform a dialing operation while voice-broadcasting "mom's home phone is being dialed" to inform the user that the currently desired operation is being performed. The requirements of customers are met while the driving safety is ensured.

Optionally, when the user performs the second operation to start the voice control mode to operate the first function, the vehicle may evaluate the first function to confirm whether the first function can be operated through the voice control mode. Such as a WeChat function, may operate using text and speech translation. For another example, some entertainment functions require occupying higher visual resources and cognitive resources of the user and cannot be operated by voice, and the user is prompted that such functions can increase driving risks and cannot be used.

Illustratively, see FIG. 15, for a prompt that the first function cannot be operated via the voice control mode. Some functions cannot be simply controlled by voice to achieve the purpose, and further thinking of a user is needed to achieve the final function, so that the functions are completely forbidden to be used. For example, after the user operates the first preset button or the first function icon on the user interface shown in fig. 10, the car machine may perform voice broadcast of "risk exists in current operation" to prompt the user that the driving risk may be increased by operating the first function at this time. The car machine continues to broadcast "ask what help is needed". The user may answer a desired operation, such as the entertainment function shown in fig. 10, and the user may voice-command the car machine to "turn on the entertainment function". At the moment, the car machine needs to judge whether the function started by the current user command can be operated through voice control, and the car machine can judge that the function cannot be used in the current state because the entertainment function needs manual participation of the user and cannot be operated simply by voice, so that voice broadcasting 'the current scene entertainment function has higher risk and cannot be operated' to prevent the user from using the function, and the driving safety of the user is ensured.

It should be noted that, after the user completes the current operation in the voice control mode, the car machine may display a corresponding user interface according to the current scene of the vehicle. And after the user finishes the current operation in the voice control mode, the vehicle-mounted device does not need to switch the user interface immediately according to the scene where the current vehicle is located, but keeps displaying the current user interface within a preset time period, so that the user can continue to operate the current function by using the voice control mode, and the user does not need to operate the first operation button again to enter the current function. For example, referring to fig. 13, 14 and 15, the current user interface includes a "microphone" icon, and the user can continue to use the current function to perform related operations by clicking the icon within a preset time period. For example, in the example of fig. 13, when the user confirms that the message returned by the in-vehicle device is correct, but then wants to continue to return to mom, the user may click the "microphone" icon to instruct the in-vehicle device to return to the corresponding content again. Or the 'microphone' icon can be clicked to command the car machine to 'view the next new message' or 'reply to colleague A' tomorrow me is not working ',' and the like. By adding the function to the user interface in the voice control mode, repeated operations of the user can be reduced, efficiency can be improved, and the user can be further enabled to focus attention on vehicle driving.

It is understood that the "microphone" icon is merely an exemplary representation, and other icons or other forms may be used to enable the car machine to satisfy the above functions, which is not specifically limited in the embodiment of the present application. Of course, the icons may not be set for realizing the continuous use of the voice control mode, and the car machine may be directly configured to be in the voice control mode, and after the current voice operation of the user is completed, the car machine is kept in the voice control mode within a preset time period, so that the user can directly use the voice to operate the function on the car machine touch screen. The embodiments of the present application are not particularly limited.

Optionally, in the step S404, when the in-vehicle device determines that the vehicle is in the preset scene, referring to fig. 5, step S405 does not need to be immediately executed, but step S407 is first executed to determine whether the current vehicle speed is greater than a second preset speed, where the second preset speed is a minimum speed limit corresponding to the preset scene. That is, step S407 may be executed, so that when the vehicle of the user is in the preset scene and the vehicle speed is low, all functions on the touch screen of the vehicle device may be used, and a better experience is provided for the user.

And S407, the vehicle machine determines that the current vehicle speed is greater than a second preset speed. If the vehicle machine determines that the current vehicle speed is greater than the second preset speed, step S405 is executed. If the vehicle machine determines that the current vehicle speed is less than or equal to the second preset speed, step S403 is executed.

Specifically, the second preset speed is a minimum speed limit in the speed limits corresponding to the preset scenes, different speed limits (second preset speeds) can be respectively and correspondingly set according to different preset scenes, and all the second preset speeds are combined to form a second preset speed set. When the road condition is complex, the user may be in several preset scenes at the same time. For example, when the vehicle runs through a high-risk road section at night, the vehicle machine determines that the vehicle is in two preset scenes, namely "night running" and "high-risk road section", two second preset speeds corresponding to the two current scenes need to be obtained according to a second preset speed set, and then a smaller second preset speed is obtained and is used as a judgment basis for the vehicle machine to display the user interface. When the user drives the vehicle in a preset scene, a second preset speed corresponding to the current scene can be obtained according to a second preset speed set, and the second preset speed is used as a judgment basis for displaying the user interface on the vehicle. When the current vehicle speed of the vehicle driven by the user is higher than the second preset speed corresponding to any scene, the vehicle speed is considered to be higher at this time, and high attention needs to be paid to the vehicle driven, that is, the step S407 determines to be yes. Of course, the speed limit corresponding to the preset scene may also be uniformly customized to a certain second preset speed, and when the current vehicle speed of the user is higher than the second preset speed, the current vehicle speed is determined to be yes. The second preset speed set and the second preset speed are preset by a manufacturer according to vehicle performance or preset by a vehicle machine according to user operation habits.

Illustratively, different speed limit limits (second preset speeds) are respectively set according to different preset scenes to form a second preset speed set. For example, when the vehicle runs on a road section with dense pedestrian flow, the second preset speed is set to be 30 km/h; when the vehicle runs at night, the second preset speed is set to be 40 km/h; when the high-risk road section runs, the second preset speed is set to be 15 km/h; when the vehicle runs in severe weather, the second preset speed is set to be 20 km/h; and when the speed limit is the road section A, setting the second preset speed to be 50% A, for example, when the current speed limit is 60km/h, setting the second preset speed to be 30 km/h. Then a second set of preset speeds 30, 40, 15, 20, 50% a km/h can be obtained. And then, the vehicle machine judges the second preset speeds respectively corresponding to the preset scenes of the current user, and further obtains the minimum second preset speed in all the second preset speeds corresponding to the scenes of the current vehicle. The current vehicle speed is greater than the minimum second preset speed, which indicates that the vehicle is currently in a scene requiring high attention, and further requires the user to concentrate the attention on driving the vehicle, so step S405 is executed, that is, the vehicle displays the first user interface hiding or not allowing the user to operate the first function.

For example, in the preset scenes, some scenes are not good for speed limit distinction, or the second preset speeds corresponding to different preset scenes are similar. Accordingly, a uniform second preset speed may be established for the preset scene. For example, the second preset speed is uniformly set to be 20km/h in the preset scene. At the moment, whether the current vehicle speed is greater than a second preset speed or not is judged according to the current vehicle speed of the vehicle driven by the user, and whether the user needs to pay high attention currently or not is further judged, namely, a corresponding user interface displayed by the vehicle machine is obtained.

In another possible implementation, since even in the same preset scenario, it is possible to make different second preset speeds under different conditions. The second preset speed is thus established in combination with different conditions of different users or different situation conditions of the vehicle performance.

Optionally, the driving proficiency of the user can influence the operation and use of the vehicle machine by the user. Therefore, the second preset speed of the corresponding scene can be set according to factors influencing the driving proficiency of the user, such as the driving age of the user. For example, for a novice driver, the vehicle is in a high-speed driving state when the vehicle speed exceeds 55km/h, and the driver cannot pay too much attention to operate the vehicle machine; however, for the old driver, the vehicle speed exceeding 65km/h cannot use much attention for the vehicle machine operation. In other words, the driving proficiency of the user can be determined according to the driving age of the user and other factors, and different second preset speeds are set for different scenes to form a second preset speed set. Finally, a different second set of preset speeds may be selected by the user or first configured by the manufacturer and then modified by annual inspection. Of course, the car machine may further configure the corresponding mode for the user according to the operation of the user. Wherein the different configuration modes are different second preset speed sets configured for different driving proficiency levels. For example: the user may be classified into three levels according to the driving proficiency of the user: class a, class B and class C. Then, the user of the level a is considered to be most skilled in driving, and the second preset speed corresponding to different preset scenes of the user of the level a can be set to be a higher speed; the driving proficiency of the class B user is a general level, the second preset speeds corresponding to different preset scenes of the class B user can be set to be a medium level, and the second speed set corresponding to the class B user can be used as a default second preset speed set, so that vehicles which cannot determine the driving proficiency of the user are all configured with the class B second preset speed set. The class C user may then use a second set of preset speeds set for novice drivers.

Optionally, the health condition or age of the user may also have a certain effect on driving safety. Therefore, the second preset speed of the corresponding scene may be set according to factors such as the age of the user, which affect the driving state of the user. For example, if the user has a heart disease and cannot better cope with the emergency, the second preset speed set of the user needs to be set lower to ensure the driving safety of the user. Alternatively, the user is older, which will make the response speed slower, and the second preset speed set of the user needs to be made slower. Certainly, the camera inside the vehicle or of the mobile phone can be used for capturing the facial expression of the user, an image analysis technology is further adopted, whether the current state of the user is abnormal or not is analyzed, if the state of the user is not good, the vehicle machine can set a lower second preset speed set, the situation in a preset scene can be responded by the user, and the driving safety of the user is guaranteed.

Optionally, the performance of the vehicle may also vary with respect to the handling capacity of the emergency situation. Therefore, the second preset speed sets corresponding to different preset scenes can be set according to different vehicle performances. For example, a vehicle with poor performance may have a poor braking function, and thus, in case of an emergency, the vehicle cannot brake in time to ensure the safety of the user. Therefore, a lower second preset speed set also needs to be formulated, so that the user can touch and operate all functions of the touch screen of the car machine at a lower car speed, and further, the attention of the user is ensured to be enough to deal with the emergency situation.

Of course, besides the above-mentioned cases, the setting of the second preset speed in different preset scenes may be influenced by other conditions of the user and the vehicle, and the embodiment of the present application is not particularly limited.

In one possible implementation, a first time threshold may also be set. For example, when the user interface is the first user interface, the condition that the car-mounted device touch screen displays the user interface including all functions may be met in a scene where the user is located at the next time, and then interface switching does not need to be performed immediately. And the user interface needs to be switched after the current state retention time exceeds the first time threshold. Because the driving condition of the vehicle on the road is complex, the vehicle speed may be temporarily reduced due to an emergency, and at this time, the user needs to pay more attention to observe the road condition for analysis, but cannot use too much visual resources and cognitive resources for user interface operation, so that the driving safety of the user can be further ensured by setting the first time threshold.

In a possible implementation manner, when the user does not complete the operation on the touch screen displaying the second user interface and the scene where the user is located is switched to the scene where the vehicle-mounted device is required to display the first user interface, the current operation of the user needs to be immediately interrupted to switch the user interfaces, so as to ensure the driving safety of the user. Or, the user interface switching operation can be performed after the user completes the current operation, but the user is prompted to have a driving risk in the current scene through voice broadcasting, so that the driving safety of the user is guaranteed while the user requirements are met.

Therefore, the method for displaying the user interface can set the second preset speed on the basis of setting the preset scene and the first preset speed, further can judge the user interface to be displayed according to the scene where the vehicle is located and the real-time speed of driving, and when the user needs to pay high attention, the vehicle machine can display the first user interface, so that the driving safety of the user is guaranteed. In addition, the setting of the second operation function of the user can be detected, so that the user can operate the first function in the first user interface in other modes without occupying visual resources or cognitive resources of the user, and the user experience is improved. The method and the device have the advantages that the situation that in the prior art, all functions are displayed on the user interface constantly, so that the user needs to operate the functions which occupy high visual resources and cognitive resources in a distracted mode when needing to drive the vehicle with high concentration, and driving is not safe is caused.
