On the basis of the above-mentioned embodiments, the screen display method provided by the present application is described in detail below with reference to fig. 3 to 11, fig. 3 is a second flowchart of the screen display method according to the embodiment of the present application, fig. 4 is a schematic diagram of selecting a secondary screen setting mode according to the embodiment of the present application, fig. 5 is a schematic view of a setting of a first screen saver type provided in an embodiment of the present application, fig. 6 is a schematic view of a setting of a second screen saver type provided in an embodiment of the present application, fig. 7 is a schematic view of a third setup of a screen saver type provided in an embodiment of the present application, fig. 8 is a schematic view of an implementation of a first storage space provided in an embodiment of the present application, fig. 9 is a first schematic diagram of implementation of determining the driving information of the vehicle according to the embodiment of the present application, fig. 10 is a second schematic diagram of implementation of determining the driving information of the vehicle according to the embodiment of the present application, fig. 11 is a schematic implementation diagram of a display input box under a third screen saver type according to an embodiment of the present application.

As shown in fig. 3, the method includes:

s301, acquiring a screen setting mode, wherein the screen setting mode is a main screen setting mode or an auxiliary screen setting mode.

The implementation manner of S301 is similar to that of S201, and based on the above description, a possible selection manner of the sub-screen setting mode is described below with reference to fig. 4.

As shown in fig. 4, assuming that a virtual control 401 is currently provided on the interface of the main screen, the virtual control 401 being used to indicate that the sub-screen setting mode is currently selected, it may be determined that the current screen setting mode is the sub-screen setting mode, for example, when an operation for the virtual control 401 is detected.

In an actual implementation process, the setting mode of the virtual control may be selected according to an actual requirement, and besides the implementation mode of the virtual control, a secondary screen setting mode, such as voice recognition, may also be determined according to other indication information.

And the implementation mode of the main screen setting mode is similar to that of the auxiliary screen setting mode, and is not described again here.

S302, when the screen setting mode is the auxiliary screen setting mode, responding to the screen saver type selection operation acted on the main screen, and determining the target screen saver type.

Based on the above description, in this embodiment, with reference to fig. 5 to fig. 7, three specific screen saver types are taken as examples to further describe the screen saver type selection operation and the target screen saver type.

In one possible implementation, the screensaver types may include, for example, but are not limited to: a first screen saver type, wherein the first screen saver type is used for indicating that screen saver information of the secondary screen is the same as screen saver information of the primary screen; a second screen saver type for indicating screen saver information of the sub-screen to display driving information of the vehicle; a third screen saver type, wherein the third screen saver type is for indicating that the screen saver information of the secondary screen displays the custom multimedia information.

For example, first, referring to fig. 5, a first screen saver type is described, and for example, after the virtual control 500 corresponding to the sub-screen setting mode is operated, a selection control corresponding to each screen saver type is displayed on the main screen.

As shown in fig. 5, selection controls corresponding to the respective screen saver types are currently displayed on the home screen, where a first screen saver type corresponds to a control of "system linkage" in fig. 5, for example, a second screen saver type may correspond to a control of "triple list" in fig. 5, and a third screen saver type may correspond to a control of "custom" in fig. 5, for example.

Assuming that a click operation on the selection control 501 for "system linkage" is currently detected, an introduction for the first screen saver type can be displayed on the interface of the main screen, as shown in fig. 5, a text content that "in this mode, the sub-screen saver type will be consistent with or the same as the main screen saver type" is displayed, and through the display of the text content, the user can quickly and effectively determine the implementation manner of the screen saver type corresponding to the current selection control 501.

Then, for example, when the operation on the application control 502 on the main screen is detected, it may be determined that the first screen saver type corresponding to the current system linkage control is selected, and then it may be determined that the target screen saver type is the first screen saver type, that is, the screen saver information of the secondary screen and the screen saver information of the main screen are set to be the same.

In the implementation process described above, the screensaver type selection operation may include, for example, an operation for the selection control 501 and an operation for the application control 502, where a specific operation may be, for example, a click operation, or may also be a long-press operation, and the like, which is not limited in this embodiment.

Next, referring to fig. 6, a second screen saver type is described, and based on the above description, it can be determined that the screen saver information of the second screen saver type indicates that the driving information of the vehicle is displayed, and in a possible implementation, the driving information of the vehicle may include at least one of the following: the vehicle speed, the speed per hour and the water temperature are selected according to actual requirements in the actual implementation process, and all information related to vehicle running can be used as the vehicle running information in this embodiment, which is not limited in this embodiment.

The screen saver information is described below by taking the running information of the three vehicles, i.e., the vehicle speed, the speed per hour and the water temperature, and the implementation manner of displaying the screen saver information by the running information of the other vehicles is similar and is not described herein again.

Similarly, after the virtual control 600 corresponding to the secondary screen setting mode is operated, the selection controls corresponding to the respective types of screen savers may be displayed on the main screen, and each selection control is similar to fig. 5, and is not described herein again.

Assuming that a click operation on the selection control 601 for the triple list is currently detected, an introduction for the second screen saver type can be displayed on the interface of the main screen, as shown in fig. 6, text that "in this mode, the auxiliary screen saver type is switched to the triple list and is displayed in synchronization with the vehicle rotation speed, the speed per hour and the water temperature" is displayed, and through the display of the text, the user can quickly and effectively determine the implementation manner of the screen saver type corresponding to the current selection control 601.

Thereafter, for example, when an operation on the application control 602 on the main screen is detected, it may be determined that the second screen saver type corresponding to the current triple play control is selected, and then it may be determined that the target screen saver type is the second screen saver type, that is, the screen saver information of the secondary screen is set to display the driving information of the vehicle.

In the implementation process described above, the screensaver type selection operation may include, for example, an operation for the selection control 601 and an operation for the application control 602, where a specific operation may be, for example, a click operation, or may also be a long-press operation, and the like, which is not limited in this embodiment.

Similarly, after the virtual control 700 corresponding to the secondary screen saver setting mode is operated, the selection controls corresponding to the screen saver types may be displayed on the main screen, and each selection control is similar to the selection control shown in fig. 5, and will not be described again here.

Assuming that a click operation for the "custom" selection control 701 is currently detected, because the third screen saver type is a screen saver type of custom media information, a plurality of selectable screen saver styles can be directly provided on the interface of the main screen, wherein the screen saver styles can be understood as screen saver pictures for the user to select and input corresponding custom content, as shown in fig. 7, 5 screen saver styles are currently provided, and the default content is "grandma speciality", after which the user can edit the text content by himself.

Then, for example, when an operation on the application control 702 on the primary screen is detected, it may be determined that the third screen saver type corresponding to the current custom control is selected, and then it may be determined that the target screen saver type is the third screen saver type, that is, the screen saver information of the secondary screen is set as the custom media information.

In the implementation process described above, the screensaver type selection operation may include, for example, an operation for the selection control 701 and an operation for the application control 702, where a specific operation may be, for example, a click operation, or may also be a long-press operation, and the like, which is not limited in this embodiment.

It should be further noted that, after the setting of the sub-screen saver is selected, corresponding content needs to be correspondingly displayed on the main screen, and in a possible implementation manner, for example, the corresponding content may be displayed in a linkage manner by default, or content corresponding to other types of screen savers may also be displayed by default.

In the above description, three types of screensaver are taken as examples in conjunction with fig. 5 to fig. 7, and an exemplary description is given to an implementation manner for determining a target type of a screensaver according to a screensaver type selection operation.

S303, acquiring a screen saver display instruction.

It can be understood that after the target screen saver type is determined, the screen saver information corresponding to the target screen saver type is not displayed immediately, because the purpose of displaying the screen saver information is to display related content when a screen is idle so as to protect the screen, after the target screen saver type is determined, only the target screen saver type specifically displayed when the screen saver information needs to be displayed is determined, and the specific display of the screen saver information also needs to be triggered correspondingly.

In one possible implementation, for example, a screen saver display instruction may be obtained, where the screen saver display instruction is used to instruct display of screen saver information corresponding to the target screen saver type.

In this embodiment, the screen saver display instruction may be triggered by a preset key on the vehicle-mounted device, where the preset key may be a start key (power key), for example, after a user presses the power key for a short time, the screen saver display instruction is generated by triggering, and accordingly, the processor may obtain the screen saver display instruction, or the preset key may also be other possible cases in the vehicle, which is similar in implementation manner, and this embodiment is not limited thereto.

Or, the screen saver display instruction may be triggered when the vehicle-mounted device enters a preset state, where the preset state may be, for example, an Adaptive Cruise Control (ACC) state, specifically, the ignition switch of the vehicle generally has four gears, one of which is an ACC gear, and the ACC gear refers to a state where, before the vehicle is not started, if the ignition switch is turned to the ACC gear, some devices with less power consumption, such as a radio, a cigarette lighter, and the like, are powered on, and when the vehicle is ignited, a strong current is required, and then the ACC gear stops supplying power, and when the vehicle is ignited, the power supply starts again.

Therefore, when the vehicle is in the ACC state, the screen saver can be displayed, for example, when it is determined that the ignition switch is shifted to the ACC gear, the screen saver display instruction can be triggered, and accordingly, the processor can acquire the screen saver display instruction.

In an actual implementation process, an implementation manner for generating the screen saver display instruction may also be selected and set according to actual requirements, as long as the screen saver display instruction is generated under a condition that the screen saver display is required, for example, when the operation instruction is not received within a preset time period of the secondary screen, the generation of the screen saver display instruction may be triggered, and the like, and the specific generation manner is not limited in this embodiment.

S304, responding to the screen saver display instruction, and determining the screen saver information of the secondary screen according to the target screen saver type.

After the screen saver display instruction is acquired, the screen saver display instruction needs to be responded, so that the screen saver information is displayed in the secondary screen.

Based on the above description, it can be determined that the target screen saver type is determined in this embodiment, each screen saver type corresponds to respective screen saver information, and currently, the screen saver is set for the secondary screen, so that the screen saver information of the secondary screen can be determined according to the target screen saver type.

In one possible implementation, the screen saver information may be located in the target storage space, for example, and then, for example, the screen saver information corresponding to the target screen saver type may be determined from the target storage space according to the target screen saver type.

Further details of the implementation of determining screen saver information are provided, assuming the above example is continued, taking the three screen saver types described above as examples.

In one possible implementation, the current target screen saver type is assumed to be a first screen saver type, where the first screen saver type is used to indicate that the screen saver information for the secondary screen and the screen saver information for the primary screen are the same.

Assuming that the screen saver information of the secondary screen is currently acquired from the target storage space, the target storage space may be, for example, a first storage space for storing the screen saver information of the primary screen.

Therefore, when determining the screen saver information of the secondary screen, for example, the screen saver information currently applied by the primary screen may be acquired from the first storage space, and then the screen saver information currently applied by the primary screen is determined as the screen saver information of the secondary screen.

In one possible implementation, the currently used screen saver information of the main screen may include a first setting identifier, for example, and then the screen saver information of the main screen including the first setting identifier may be determined as the screen saver information of the secondary screen.

For example, it can be understood in conjunction with fig. 8, as shown in fig. 8, it is assumed that the first storage space currently used for storing the screen saver information of the main screen is a storage space corresponding to the first file path shown in fig. 8, where the first file path may be, for example,/data/system/the me/scanner/wallpaper/csd/, where csd is (center stack display).

As shown in fig. 8, for example, 3 pieces of screen saver information, that is, screen saver information 1, screen saver information 2, and screen saver information 3, may be stored in the first storage space corresponding to the first file path, and it is understood that these pieces of screen saver information may be, for example, stored in the file path after being downloaded in advance, where the screen saver information of the main screen may include screen saver images similar to the screen saver information of the above-described sub-screen, or the screen saver information may include screen saver images and additional information, where the additional information includes at least one of: the running information, the time information and the user-defined multimedia information of the vehicle.

If the currently set screen saver information of the main screen includes the setting flag to indicate that the screen saver information is currently applied, among the stored plurality of screen saver information, for example, in the example of fig. 8, the screen saver information 2 includes the setting flag, it may be determined that the current screen saver information 2 is the screen saver information applied by the main screen.

Because the first screen saver type indicates that the screen saver information of the secondary screen and the screen saver information of the primary screen are the same, it is currently possible to determine the screen saver information 2 as the screen saver information of the secondary screen.

In an actual implementation process, the number, specific implementation, and the like of the screen saver information of the main screen included in the first storage space can be selected according to actual requirements, and this embodiment does not particularly limit this.

And, in another possible implementation, assuming that the current target screen saver type is a second screen saver type, wherein the first screen saver type is for indicating that the screen saver information of the secondary screen displays driving information of the vehicle.

Similarly, assuming that the screen saver information of the secondary screen is currently acquired from the target storage space, the driving information of the vehicle may be determined from, for example, a Microcontroller Unit (MCU), and the target storage space may include the MCU and a second storage space for storing the screen saver information of the secondary screen.

Therefore, when determining the screen saver information of the secondary screen, for example, the driving information of the vehicle may be determined from the MCU, where the driving information of the vehicle may include, for example, a vehicle speed, a speed per hour, a water temperature, and the like, and in an actual implementation process, a specific implementation manner of the driving information of the vehicle may be selected according to an actual requirement, which is not limited in this embodiment.

In a possible implementation manner, the driving information of the vehicle needs to be displayed in a corresponding screen saver image to enhance the diversity and the aesthetic property of the driving information display of the vehicle, where the screen saver image may be, for example, a virtual instrument panel, and then the driving information of the vehicle, such as the vehicle speed, and the vehicle water temperature, is respectively displayed through the virtual instrument panel, or the screen saver image may also be in other implementation manners, such as a static background image, and the like.

Then, for example, a screen saver image for displaying the driving information of the vehicle may be further obtained from a second storage space, where the second storage space is a storage space for storing screen saver information of a secondary screen, and in a possible implementation, the second storage space may be, for example, a storage space corresponding to a second file path, where the second file path may be, for example,/data/system/the me/scanner/wall paper/psd/, where the psd is (passenger side display).

In a possible implementation manner, a plurality of screen saver information may also be stored in the second storage space, where a mapping relationship may exist between the screen saver image for displaying the driving information of the vehicle and the second screen saver type, for example, and then the screen saver image for displaying the driving information of the vehicle corresponding to the second screen saver type may be acquired in the second storage space according to the second screen saver type, for example.

Based on the above description, it may be determined that, when the target screen saver type is the second screen saver type, the driving information of the vehicle may be determined from the MCU, and when determining the driving information of the vehicle, there may be two different implementations, for example, one is active acquisition and the other is passive reception, in the implementation of active acquisition, the driving information of the vehicle may be actively acquired from the MCU, and in the implementation of passive reception, the driving information of the vehicle from the MCU may be received, for example, and the two implementations are respectively described below.

For example, first, the implementation of passive reception may be described with reference to fig. 9, as shown in fig. 9, after the screensaver service is started, a method in an adapter interface (adapter api) may be called by a Binder, so as to register a request for monitoring driving information of a vehicle, such as a rotation speed, a speed per hour, and a water temperature, where the Binder is an inter-process communication mechanism.

Then, the vehicle service (CarService) may receive a monitoring request of the screen saver service through the Binder, and the vehicle service may respond to the monitoring request, and send the driving information of the vehicle to the screen saver service when receiving the driving information of the vehicle, it may be understood that both the screen saver service and the vehicle service are processing modules in the vehicle-mounted system, and are used to implement corresponding functions.

And when the running information of the vehicle changes, the MCU may receive the changed running information of the vehicle, such as the rotation speed, the speed per hour, and the water temperature, from the corresponding sensor through the can bus, and then report the changed running information of the vehicle to the driver (kernel) through a Serial Peripheral Interface (SPI).

After the driver receives the driving information of the Vehicle, the driving information of the Vehicle is directly reported to a Vehicle body bottom layer (Vehicle HAL) through a NetLink mechanism, wherein the NetLink is a group of Application Programming Interfaces (API) for communication between a user control and a kernel space, and is realized on a socket mechanism.

And the bottom layer of the vehicle body needs to analyze the data acquired from the drive, and after the data is analyzed and converted, the data is reported to the vehicle service through a Binder mechanism, so that the vehicle service can monitor the change of the running information of the vehicle such as the rotating speed, the speed per hour, the water temperature and the like, and then the analyzed running information of the vehicle is called back to the screen saver service, so that the running information of the vehicle from the MCU is received.

In the above description, the implementation of passive reception is described, and in the following description, with reference to fig. 10, an implementation of actively obtaining the driving information of the vehicle from the MCU is described, which is actually similar to the implementation of passive reception described in the above-described fig. 9, except that the sequence of data flow is just reversed.

As shown in fig. 10, the screen saver service may actively obtain the driving information of the vehicle by a method in the adapter interface, for example, three IDs (Identity) may be defined, for example, a rotation speed ID, a time speed ID, and a water temperature ID may be defined, and then, by means of function call, get function value () in the carfunction im is called, and the rotation speed ID, the time speed ID, and the water temperature ID are respectively transmitted, so as to create an obtaining request for the driving information of the vehicle, so as to actively obtain the rotation speed, the time speed, and the water temperature.

Specifically, as shown in fig. 10, after the screen saver service is started, the Binder may call a method in an adapter interface (adapter api) to actively acquire a rotation speed, a speed per hour, and a water temperature, and then, the Vehicle service (CarService) may receive a data acquisition request of the screen saver service through the Binder, so as to request to acquire corresponding information from a Vehicle underbody (Vehicle HAL) through the Binder.

Further, the Vehicle underbody (Vehicle HAL) acquires the traveling information of the Vehicle from the drive (kernel) through the IOCTL, wherein the IOCTL (input/output control) is a communication method used before the user space and the kernel space.

Then, the driver (kernel) requests to acquire information from the MCU through the SPI, and then the MCU can receive driving information such as the rotating speed, the speed per hour, the water temperature and the like of the vehicle from corresponding sensors through the can bus, so that the acquisition of the driving information of the vehicle is realized.

In an actual implementation process, an implementation manner of determining the driving information of the vehicle from the MCU may be selected according to an actual requirement, and may be the implementation manner of the active acquisition described above, or may also be the implementation manner of the passive reception described above, which is not limited in this embodiment.

In the above description, the implementation manner of determining the screen saver information of the secondary screen corresponding to the first screen saver type and the second screen saver type is described, and in the following description, the implementation manner of determining the screen saver information of the secondary screen corresponding to the third screen saver type is described.

And assuming that the current target screen saver type is a third screen saver type, wherein the third screen saver type is used for indicating the screen saver information of the secondary screen to display the customized multimedia information.

Similarly, assuming that the screen saver information of the secondary screen is currently acquired from the target storage space, in a possible implementation manner, the customized multimedia information may be stored in, for example, a second storage space, where the second storage space is a storage space for storing the screen saver information of the secondary screen, and the target storage space may be, for example, the second storage space, and the second storage space is similar to the above description, and is not described herein again.

Therefore, when determining the screen saver information of the secondary screen, for example, at least one piece of screen saver information may be acquired from the second storage space, where at least one piece of screen saver information of the secondary screen may be stored in the second storage space, where each piece of screen saver information may include a screen saver image, or may include a screen saver image and customized multimedia information, where the customized multimedia information is displayed on the screen saver image.

In a possible implementation manner, the determined currently applied screen saver information of the secondary screen may include, for example, a setting identifier, and then the screen saver information including a second setting identifier in at least one screen saver information of the secondary screen may be determined as the screen saver information of the secondary screen, where the second setting identifier is similar to the first setting identifier described above, and is not described here again.

It can be understood that the screen saver information of each sub-screen included in the second storage space is pre-stored in the second storage space, for example, the screen saver pictures therein need to be stored after being pre-selected by the user, and the customized media information needs to be stored after being pre-input by the user, and the implementation of the pre-determined screen saver information is described below with reference to fig. 11.

For example, at least one screen saver image may be displayed on the main screen, the screen saver image in this embodiment may be, for example, a background image for displaying the customized multimedia information input by the user, for example, a background image for displaying the customized text content, and the like, and at least one preset screen saver image may be currently displayed on the main screen, or a user-defined screen saver image may also be displayed, and this is not limited in this embodiment.

Then, according to the selection operation for any one of the screen saver images, an input box is displayed on the main screen, wherein the input box user receives the customized multimedia information,

as shown in fig. 11, assuming that a selection operation for the screen saver image 1101 is currently detected, an input box 1102 may be displayed on the main screen, and thereafter, the input box 1102 may respond to the user's operation, thereby receiving customized multimedia information, which may be, for example, customized text, customized emotions, or the like.

Then, the screen saver image corresponding to the selection operation and the custom multimedia information received in the input box are determined as a piece of screen saver information, for example, the screen saver image corresponding to 1101 in fig. 11 and the text information input by the user are determined as a piece of screen saver information.

In a possible implementation manner, the screensaver information may also be stored in a second preset space, for example, after the corresponding text is set, for example, an interface in the CarService may be triggered through an AdapterAPI interface call, the custom text may be stored, and the screensaver image selected by the user may also be stored, for example, under a second file path, which may be, for example: the second file path corresponds to a second storage space.

And S305, displaying the screen saver information on the secondary screen.

After the screen saver information of the auxiliary screen corresponding to the target screen saver type is acquired according to the target screen saver type, the screen saver information can be displayed on the auxiliary screen.

For example, screen saver information for the first screen saver type, which may be displayed with an effect such as the clock effect displayed in the preview box in fig. 5; and, for the second screen saver type of screen saver information, the effect displayed may be, for example, the triple list effect displayed by the preview box in fig. 6; and, for the screen saver information of the third screen saver type, the displayed effect may be, for example, a custom text effect displayed by the preview box in fig. 7.

In an alternative implementation manner, after determining the screen saver information of the secondary screen according to the target screen saver type, a preview instruction may be further obtained, where the preview instruction is triggered by a preview button on the primary screen.

For example, a preview button is provided in each of fig. 5, 6, and 7, and a preview instruction can be acquired after an operation of the preview button is detected.

It can be understood that the preview instruction is only for enabling the user to preview the display effect of the screen saver information, so that the screen saver information is not displayed for a long time, and for example, the screen saver information can be previewed and displayed on the secondary screen within a preset time according to the preview instruction. The specific setting of the preset duration may be selected according to actual requirements, which is not limited in this embodiment.

S306, receiving a display stopping instruction.

After the screen saver information of the sub-screen is displayed, further, the screen saver information can also be stopped from being limited, and then, for example, a display stopping instruction can be received, where the display stopping instruction can be triggered by broadcast information of the vehicle-mounted device, for example, a current vehicle needs to display related content on a screen, or the vehicle needs to be started, and the like, and the corresponding broadcast information is sent, and after the broadcast information is received, a display stopping instruction can be generated; alternatively, the display stopping instruction may be triggered by a clicking operation on the main screen or the sub-screen, for example, when the screen saver is currently displayed on the sub-screen, and when the display of the screen saver needs to be exited, for example, the display of the screen saver may be exited by clicking the main screen or the sub-screen, and the display stopping instruction may be triggered according to the clicking operation, for example.

And S307, controlling the auxiliary screen to cancel the display screen saver information according to the display stopping instruction.

After the stop display instruction is generated, the sub-screen can be controlled to cancel the display screen saver information.
