[0002] Vehicles are increasingly equipped with display screens, including not only the driver's screen but also the central control screen and even the screens behind the seats. When multiple displays are used on a single system, the brightness of each display needs to be manually adjusted. Furthermore, when the same application is used on multiple displays, the brightness of each display needs to be manually adjusted again. Furthermore, the current Android system brightness adjustment scheme is one system per display, which cannot meet the brightness management requirements of vehicle displays. Summary of the Invention

[0003] Embodiments of the present invention provide a brightness control method, a vehicle, and a storage medium.

[0004] An embodiment of the present invention provides a brightness control method for an in-vehicle system. The brightness control method includes: while the vehicle is traveling, receiving a brightness setting instruction for a current application on the in-vehicle system to set the system brightness in the cabin; determining the screen location of the current application; if the current application is on a first display screen in the cabin, adjusting the system brightness of the first display screen according to the brightness setting instruction; if the current application is on a second display screen in the cabin, adjusting the system brightness of the second display screen according to the brightness setting instruction; wherein the system brightness of the first display screen and the system brightness of the second display screen are different.

[0005] In this way, the brightness control method of the present invention can, when the brightness provision mode of the current application is set to the system brightness of the display screen, receive the brightness setting instruction of the current application on the vehicle system to set the system brightness in the cockpit, and determine the screen position of the current application. According to the brightness setting instruction, the system brightness of the corresponding display screen is adjusted to display the current application and adjust the brightness change. This can realize that one vehicle system corresponds to multiple display screens and meet the brightness management requirements of the display screens on the vehicle.

[0006] If the first display screen currently in use is in the cockpit, the system brightness of the first display screen is adjusted according to the brightness setting instruction, including: modifying the directional index information of the brightness setting instruction to the directional index information of the first brightness providing component corresponding to the first display screen; and calling the first brightness providing component to set the system brightness of the first display screen.

[0007] In this way, when the current application is on the first display screen, the first brightness providing component corresponding to the first display screen can be automatically called to set the system brightness of the first display screen, thereby achieving brightness change adjustment of the current application on the first display screen.

[0008] If the second display screen currently used in the cockpit is used, the system brightness of the second display screen is adjusted according to the brightness setting instruction, including: modifying the directional index information of the brightness setting instruction to the directional index information of the second brightness providing component corresponding to the second display screen; calling the second brightness providing component to set the system brightness of the second display screen.

[0009] In this way, when the current application is on the second display screen, the second brightness providing component corresponding to the second display screen can be automatically called to set the system brightness of the second display screen, thereby achieving brightness change adjustment of the current application on the second display screen.

[0010] The present application also provides a brightness control method for an in-vehicle system. The brightness control method includes: while the vehicle is driving, monitoring an application flow event of the current application on the in-vehicle system; determining the screen position of the current application after the flow; if the current application is on a first display screen in the cockpit, controlling the first display screen to display the current application at the system brightness of the first display screen according to the application flow event; if the current application is on a second display screen in the cockpit, controlling the second display screen to display the current application at the system brightness of the second display screen according to the application flow event; wherein the system brightness of the second display screen is different from the system brightness of the first display screen.

[0011] In this way, the brightness control method of the present invention can set the brightness provision mode of the current application to system brightness and when the current application is transferred, the current application can be displayed according to the system brightness of the display screen after the transfer, and the brightness value displayed after the current application is transferred can match the system brightness of the current display screen.

[0012] If the current application is on the first display screen in the cockpit, controlling the first display screen to display the current application at the system brightness of the first display screen according to the application flow event includes: determining an observer of the current application registered uniform resource identifier; sending the brightness change notification to the observer; and controlling the first display screen to display the current application at the system brightness of the first display screen according to the brightness change notification.

[0013] In this way, it can be ensured that when the current application is monitored to be transferred to the first display, the first display can be controlled to display the current application at the system brightness of the first display, so that the brightness value displayed after the current application is transferred can match the system brightness of the first display.

[0014] If the current application is on the second display screen in the cockpit, controlling the second display screen to display the current application at the system brightness of the second display screen according to the application flow event includes: determining an observer of the current application registered uniform resource identifier; sending the brightness change notification to the observer; and controlling the second display screen to display the current application at the system brightness of the second display screen according to the brightness change notification.

[0015] In this way, it can be ensured that when the current application is monitored to be transferred to the second display, the second display can be controlled to display the current application at the system brightness of the first display, so that the brightness value displayed after the current application is transferred can match the system brightness of the second display.

[0016] The present invention also provides a brightness control method for an in-vehicle system. The brightness control method includes: monitoring an application transfer event of a current application on the in-vehicle system while the vehicle is driving; determining the screen position of the current application after the transfer; if the current application is on a first display screen in the cabin, setting the brightness of the window corresponding to the current application on the first display screen according to the application transfer event; if the current application is on a second display screen in the cabin, setting the brightness of the window corresponding to the current application on the second display screen according to the application transfer event; wherein the window brightness of the first display screen is different from the window brightness of the second display screen.

[0017] In this way, the brightness control method of the present invention can monitor the application flow events of the current application on the vehicle system when the brightness provision mode of the current application is set to window brightness, and determine the screen position of the current application after the flow. According to the application flow event, the window brightness corresponding to the current application in the display screen is set to display the current application and adjust the brightness change. This can realize that one vehicle system corresponds to multiple display screens and meet the brightness management needs of multiple display screens on the vehicle.

[0018] The method of setting the window brightness corresponding to the current application on the first display screen according to the application flow event includes: determining the window brightness corresponding to the current application before the flow; adding the window brightness corresponding to the current application to the first position of the sequence of the corresponding brightness set of the first display screen; and the brightness control method includes: controlling the first display screen to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set.

[0019] In this way, it can be ensured that after monitoring the current application flowing to the first display screen, the window brightness corresponding to the current application can be added to the first position of the sequence of the brightness set corresponding to the first display screen, and the first display screen can be controlled to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set, so that the current application can be displayed with the window brightness of the current application after flowing to the first display screen, that is, the set window brightness of the current application can take effect on the first display screen after the flow.

[0020] If the current application is on the second display screen in the cockpit, the window brightness corresponding to the current application on the second display screen is set according to the application flow event, including: determining the window brightness corresponding to the current application before the flow; adding the window brightness corresponding to the current application to the first position of the sequence of the brightness set corresponding to the second display screen; the brightness control method includes: controlling the second display screen to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set.

[0021] In this way, it can be ensured that after monitoring the current application flowing to the second display screen, the window brightness corresponding to the current application can be added to the first position of the sequence of the brightness set corresponding to the second display screen, and the second display screen can be controlled to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set, so that the current application can be displayed with the window brightness of the current application after flowing to the second display screen, that is, the set window brightness of the current application can take effect on the second display screen after the flow.

[0022] The present invention also provides a brightness control method for an in-vehicle system. The brightness control method includes: while the vehicle is traveling, receiving a first control instruction for activating automatic brightness for a current application on the in-vehicle system; determining the screen location of the current application; if the current application is on a first display screen in the cockpit, turning on the automatic brightness master switch and the automatic brightness sub-switch corresponding to the first display screen according to the first control instruction, thereby setting the system brightness of the first display screen in automatic brightness mode; if the current application is on a second display screen in the cockpit, turning on the automatic brightness master switch and the automatic brightness sub-switch corresponding to the second display screen according to the first control instruction, thereby setting the system brightness of the second display screen in automatic brightness mode; wherein the system brightness of the first display screen and the system brightness of the second display screen are different.

[0023] In this way, the user can turn on the automatic brightness mode for any one or more of the multiple display screens in the vehicle system, thereby meeting the user's demand for the current application whose brightness is provided by the system brightness to display different brightness changes at different system brightness on different display screens.

[0024] The brightness control method includes: when the vehicle is driving, receiving a second control instruction on the vehicle system to turn off the automatic brightness of the current application; determining the screen position of the current application; if the current application is on the first display screen, turning off the automatic brightness sub-switch corresponding to the first display screen according to the second control instruction to stop setting the system brightness of the first display screen through the automatic brightness mode; if the current application is on the second display screen, turning off the automatic brightness sub-switch corresponding to the second display screen according to the second control instruction to stop setting the system brightness of the second display screen through the automatic brightness mode; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0025] In this way, the user can exit the automatic brightness mode for any one or more of the multiple display screens in the vehicle system, thereby meeting the user's demand for the current application whose brightness is provided by system brightness to display brightness changes at different system brightness on different display screens.

[0026] The brightness control method includes: when the automatic brightness sub-switch corresponding to the first display screen and the automatic brightness sub-switch corresponding to the second display screen are both turned off, turning off the automatic brightness main switch to stop setting the system brightness of the first display screen and the system brightness of the second display screen through the automatic brightness mode.

[0027] In this way, when the automatic brightness sub-switches corresponding to multiple display screens are all turned off, the automatic brightness main switch can be automatically turned off, thereby reducing the energy loss of the multi-screen vehicle system.

[0028] The present invention further provides a vehicle comprising a processor and a memory, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the brightness control method described in any one of the above embodiments is implemented.

[0029] In this way, the vehicle application of the present invention can use the above-mentioned brightness control method without worrying about which display screen the application is applied on. On multiple display screens, the brightness of the display screen where the application is currently located can be directly adjusted. After monitoring the flow of the application, there is no need to actively obtain the brightness of the current display screen. The target brightness information of the current display screen will be directly notified, so that the current display screen will directly make corresponding changes to the brightness value, which can meet the brightness management needs of the display screens on the vehicle.

[0030] The present invention further provides a non-volatile computer-readable storage medium containing a computer program. When the computer program is executed by one or more processors, the brightness control method described in any one of the above embodiments is implemented.

[0031] In this way, the storage medium of the present invention can apply the above-mentioned brightness control method without having to worry about which display screen the application is on.

It will be directly notified of the target brightness information of the current display screen, so that the current display screen directly makes the corresponding brightness value change, which can meet the brightness management requirements of the display screen on the vehicle.

[0052] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present invention, and should not be understood as limiting the embodiments of the present invention.

[0053] Currently, when the brightness provider mode of the current application is set to the system brightness of the display screen, when there are multiple displays on a single system, if the application wants to adjust the system brightness of different displays on different displays, it needs to set the pointing index information (key) of different brightness provider components (provider). However, third-party applications do not care about the number of displays in the system and only set the pointing index information (key) of the brightness provider component (provider) of the native main screen. As a result, the current application can only adjust the main screen brightness on the main screen.

[0054] In view of this, please see Figure 1 The present invention provides a brightness control method for a multi-screen vehicle system, which can realize the brightness setting of the same application on different screens, so that the same application is set to the system brightness corresponding to different screens when it is on different screens. The brightness control method includes:

[0055] 01: When the vehicle is driving, receive the brightness setting instruction of the current application in the vehicle system to set the system brightness in the cabin;

[0056] 03: Determine the screen position of the current application;

[0057] 05: If the current application is the first display screen in the cockpit, adjust the system brightness of the first display screen according to the brightness setting instruction;

[0058] 07: If a second display screen is currently used in the cockpit, adjust the system brightness of the second display screen according to the brightness setting instruction; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0059] The present invention provides a vehicle, which includes a processor and a memory, wherein a computer program is stored in the memory. The processor is configured to receive, while the vehicle is traveling, a brightness setting instruction for setting the system brightness of a current application in a cockpit on a vehicle system; determine the screen position of the current application; if the current application is a first display screen in the cockpit, adjust the system brightness of the first display screen according to the brightness setting instruction; if the current application is a second display screen in the cockpit, adjust the system brightness of the second display screen according to the brightness setting instruction; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0060] The brightness of the current application is set to the system brightness of the display. The current application can be an application that comes with the vehicle system or a third-party application installed by the user.

[0061] First, while the vehicle is in motion, a brightness setting command is received from a current application on the vehicle system to set the system brightness in the cabin. The brightness setting command is either a touchscreen command from a user setting the brightness of the current application to the system brightness or a voice command from a user setting the brightness of the current application to the system brightness.

[0062] The current app's brightness setting command in the cockpit sets the system brightness to the display's system brightness using the app's native brightness provider. This means the app's brightness display mode can be set to the system brightness mode, allowing the app to automatically adjust its display brightness on different displays based on the system brightness.

[0063] Then, the screen position of the current application is determined. If the current application is on the first display screen in the cockpit, the system brightness of the first display screen is adjusted according to the brightness setting instruction. If the current application is on the second display screen in the cockpit, the system brightness of the second display screen is adjusted according to the brightness setting instruction. The system brightness of the first display screen and the system brightness of the second display screen are different. It should be noted that the second display screen refers to any display screen in the vehicle system that can be adjusted in brightness through the application and is different from the first display screen. For example, the first display screen can be the main driver's display screen in the vehicle cockpit, and the second display screen can be the passenger driver's display screen in the vehicle cockpit, etc.

[0064] For example, Figure 2 As shown, if it is determined that the screen position of the current application A is on display screen 1, that is, the first display screen is display screen 1, the system brightness of display screen 1 can be adjusted according to the brightness setting instruction, thereby changing the display brightness of the current application A on display screen 1.

[0065] If it is determined that the screen position of the current application A is on display 2 with a system brightness different from that of display 1, that is, the second display is display 2, the system brightness of display 2 can be adjusted according to the brightness setting instruction, thereby changing the display brightness of the current application A on display 2.

[0066] In this way, the brightness control method of the present invention can, when the brightness provision mode of the current application is set to the system brightness of the display screen, receive the brightness setting instruction of the current application on the vehicle system to set the system brightness in the cockpit, and determine the screen position of the current application. According to the brightness setting instruction, the system brightness of the corresponding display screen is adjusted to display the current application and adjust the brightness change. This can realize that one vehicle system corresponds to multiple display screens and meet the brightness management requirements of the display screens on the vehicle.

[0067] See also Figure 3 , step 05 includes:

[0068] 051: modify the directional index information of the brightness setting instruction to the directional index information of the first brightness providing component corresponding to the first display screen;

[0069] 052: Call the first brightness providing component to set the system brightness of the first display screen.

[0070] The processor is configured to modify the directional index information of the brightness setting instruction to the directional index information of the first brightness providing component corresponding to the first display screen; and call the first brightness providing component to set the system brightness of the first display screen.

[0071] Specifically, the brightness providing component (provider) receives the pointing index information (key) of the brightness setting instruction that sets the current application as the system brightness, and determines that the application location that currently calls the brightness providing component (provider) is the first display screen. It can automatically modify the pointing index information (key) of the brightness setting instruction to the pointing index information (key1) of the first brightness providing component (provider1) corresponding to the first display screen, and then call the first brightness providing component (provider1) to set the system brightness of the first display screen.

[0072] In this way, when the current application is on the first display screen, the first brightness providing component corresponding to the first display screen can be automatically called to set the system brightness of the first display screen, thereby achieving brightness change adjustment of the current application on the first display screen.

[0073] See also Figure 4 , step 07 includes:

[0074] 071: Modify the directional index information of the brightness setting instruction to the directional index information of the second brightness providing component corresponding to the second display screen;

[0075] 072: Call the second brightness providing component to set the system brightness of the second display.

[0076] The processor is used to modify the directional index information of the brightness setting instruction to the directional index information of the second brightness providing component corresponding to the second display screen; and call the second brightness providing component to set the system brightness of the second display screen.

[0077] Specifically, the brightness providing component (provider) receives the pointing index information (key) of the brightness setting instruction that sets the current application as the system brightness, and determines that the application location that currently calls the brightness providing component (provider) is the second display screen. It can automatically modify the pointing index information (key) of the brightness setting instruction to the pointing index information (key2) of the second brightness providing component (provider2) corresponding to the second display screen, and then call the second brightness providing component (provider2) to set the system brightness of the first display screen.

[0078] In this way, when the current application is on the second display screen, the second brightness providing component corresponding to the second display screen can be automatically called to set the system brightness of the second display screen, thereby achieving brightness change adjustment of the current application on the second display screen.

[0079] In addition, when the application that sets the system brightness is transferred, since there is no actual brightness change, the application cannot obtain the system brightness value of the display after the transfer, resulting in the brightness value displayed by the application after the transfer not matching the current display brightness. Only by resetting the system brightness value for the current display brightness can the application display brightness and the display system brightness be consistent.

[0080] In view of this, please see Figure 5 The present invention also provides a brightness control method for a vehicle-mounted system. The brightness control method includes:

[0081] 02: When the vehicle is driving, monitor the application flow events of the current application on the vehicle system;

[0082] 04: Determine the screen position of the current application after the transfer;

[0083] 06: If the current application is on the first display screen in the cockpit, control the first display screen to display the current application at the system brightness of the first display screen according to the application flow event;

[0084] 08: If the current application is on the second display screen in the cockpit, control the second display screen to display the current application at the system brightness of the second display screen according to the application flow event; wherein the system brightness of the second display screen is different from the system brightness of the first display screen.

[0085] The present invention provides a vehicle, which includes a processor and a memory, wherein the memory stores a computer program, and the processor is used to monitor the application flow event of the current application on the vehicle system when the vehicle is driving; determine the screen position of the current application after the flow; if the current application is on the first display screen in the cockpit, control the first display screen to display the current application with the system brightness of the first display screen according to the application flow event; if the current application is on the second display screen in the cockpit, control the second display screen to display the current application with the system brightness of the second display screen according to the application flow event; wherein the system brightness of the second display screen is different from the system brightness of the first display screen. It should be noted that the second display screen refers to any one of the multiple screens in the vehicle system that can be adjusted in brightness by an application and is different from the first display screen. For example, the first display screen can be the main driver's display screen in the vehicle cockpit, and the second display screen can be the co-driver's display screen in the vehicle cockpit, etc.

[0086] Specifically, for example, Figure 6 As shown, the current application A is an application that sets the system brightness in a brightness provisioning manner. When the current application A flows from display 2 to display 1, while the vehicle is driving, the application flow event of the current application A on the vehicle system can be monitored. If it is determined that the screen location of the current application after the flow is display 1, that is, the first display is display 1, then display 1 can be controlled to display the current application at the system brightness of display 1 based on the application flow event. The system brightness of display 2 is different from the system brightness of display 1.

[0087] When the current application A flows from display screen 1 to display screen 2, while the vehicle is driving, the application flow event of the current application A on the vehicle system can be monitored, and it can be determined that the screen position of the current application after the flow is display screen 2, that is, the second display screen is display screen 2. Then, according to the application flow event, display screen 2 can be controlled to display the current application at the system brightness of display screen 2.

[0088] In this way, the brightness control method of the present invention can set the brightness provision mode of the current application to system brightness and when the current application is transferred, the current application can be displayed according to the system brightness of the display screen after the transfer, and the brightness value displayed after the current application is transferred can match the system brightness of the current display screen.

[0089] See also Figure 7 , step 06 includes:

[0090] 061: Determine the observer of the current application registered uniform resource identifier;

[0091] 062: Send brightness change notification to the observer;

[0092] 063: Control the first display screen to display the current application at the system brightness of the first display screen according to the brightness change notification.

[0093] The processor is used to determine the observer of the current application registered uniform resource identifier; send a brightness change notification to the observer; and control the first display screen to display the current application at the system brightness of the first display screen according to the brightness change notification.

[0094] After monitoring the application flow event of the current application on the vehicle system and the current application flows to the first display screen, the observer of the current application registered uniform resource identifier (URI) can be determined first, and the observer of the registered uniform resource identifier (URI) can be notified of the brightness change, that is, a brightness change notification is sent to the observer.

[0095] Then, after receiving the brightness change notification, the current application can refresh the interface brightness value of the current application for display, that is, control the first display screen where the current application is located to display the current application at the system brightness of the first display screen.

[0096] In this way, it can be ensured that when the current application is monitored to be transferred to the first display, the first display can be controlled to display the current application at the system brightness of the first display, so that the brightness value displayed after the current application is transferred can match the system brightness of the first display.

[0097] See also Figure 8 , step 08 includes:

[0098] 081: Determine the observer of the current application registered uniform resource identifier;

[0099] 082: Send brightness change notification to the observer;

[0100] 083: Control the second display screen to display the current application at the system brightness of the second display screen according to the brightness change notification.

[0101] The processor is used to determine the observer of the current application registered uniform resource identifier; send a brightness change notification to the observer; and control the second display screen to display the current application at the system brightness of the second display screen according to the brightness change notification.

[0102] After monitoring the application flow event of the current application on the vehicle system and the current application flows to the second display screen, the observer of the current application registered uniform resource identifier (URI) can be determined first, and the observer of the registered uniform resource identifier (URI) can be notified that the brightness has changed, that is, a brightness change notification is sent to the observer. Then, after receiving the brightness change notification that the brightness has changed, the current application can refresh the interface brightness value of the current application for display, that is, control the second display screen where the current application is located to display the current application with the system brightness of the second display screen.

[0103] In this way, it can be ensured that when the current application is monitored to be transferred to the second display, the second display can be controlled to display the current application at the system brightness of the first display, so that the brightness value displayed after the current application is transferred can match the system brightness of the second display.

[0104] In addition, when the brightness provision method of the current application is set to window brightness, the native window brightness setting process is to set it layer by layer through the window stack relationship until the vehicle power (power) setting brightness. However, there is only one window stack, and multiple displays are recorded as a whole display. As a result, no matter which display the current application is on, the set window brightness will only take effect on the main screen.

[0105] In view of this, please see Figure 9 The present invention also provides a brightness control method for a vehicle-mounted system. The brightness control method includes:

[0106] 11: When the vehicle is driving, monitor the application flow events of the current application on the vehicle system;

[0107] 13: Determine the screen position of the current application after the transfer;

[0108] 15: If the current application is on the first display screen in the cockpit, set the brightness of the window corresponding to the current application on the first display screen according to the application flow event;

[0109] 17: If the current application is on the second display screen in the cockpit, set the window brightness corresponding to the current application on the second display screen according to the application flow event; wherein the window brightness of the first display screen is different from the window brightness of the second display screen.

[0110] The present invention also provides a vehicle, which includes a processor and a memory, wherein a computer program is stored in the memory, and the processor is used to monitor the application flow event of the current application on the vehicle system when the vehicle is driving; determine the screen position of the current application after the flow; if the current application is on the first display screen in the cockpit, set the window brightness corresponding to the current application on the first display screen according to the application flow event; if the current application is on the second display screen in the cockpit, set the window brightness corresponding to the current application on the second display screen according to the application flow event; wherein the window brightness of the first display screen is different from the window brightness of the second display screen.

[0111] At this time, the current application's brightness is set to Window Brightness, which refers to the brightness of the application window. When the current application's brightness is set to Window Brightness, when the application window of the current application is displayed on the display, the application is displayed at the brightness corresponding to the application window. After the application window of the current application is exited on the display, the desktop of the display returns to the system brightness corresponding to the display.

[0112] The current application can be an application that comes with the vehicle system or a third-party application installed by the user.

[0113] While the vehicle is in motion, the system monitors the application transfer event of the current application on the vehicle system and determines the screen location of the current application after the transfer. The application transfer event can be an event in which the user triggers the application transfer and related operations by performing a predetermined sliding gesture on the display screen before the current application transfers or pressing a preset transfer button on the display screen.

[0114] For example, Figure 10 As shown, the sliding gesture can be a gesture of sliding from point P3 to point P4, and the preset flow button can also be as shown in FIG. Figure 10 As shown in . That is, when the user makes the gesture of sliding from point P3 to point P4 or presses the transfer button, it can trigger the setting operation of application B transferring from display screen 3 to other display screens. For example, a pop-up window asks the user to confirm "Please confirm to transfer to display screen ()". When the user fills in "display screen (4)" and clicks "Confirm", application B can transfer from display screen 3 to display screen 4.

[0115] If the current application is on the first display screen in the cockpit, the window brightness corresponding to the current application on the first display screen is set according to the application flow event; if the current application is on the second display screen in the cockpit, the window brightness corresponding to the current application on the second display screen is set according to the application flow event; wherein the window brightness of the first display screen is different from the window brightness of the second display screen. It should be noted that the second display screen refers to any display screen in the vehicle system that can be adjusted in brightness through the application and is different from the first display screen. For example, the first display screen can be the main driver's display screen in the vehicle cockpit, and the second display screen can be the co-driver's display screen in the vehicle cockpit, etc.

[0116] For example, Figure 11 As shown, if it is determined that the screen location of the current application B is transferred to display screen 1 in the cockpit, the window brightness corresponding to the current application on display screen 1 can be set according to the application transfer event, thereby changing the display brightness of the current application B on display screen 1. If it is determined that the screen location of the current application B is transferred to display screen 2 in the cockpit, the window brightness corresponding to the current application on display screen 2 can be set according to the application transfer event, thereby changing the display brightness of the current application B on display screen 2.

[0117] In this way, the brightness control method of the present invention can monitor the application flow events of the current application on the vehicle system when the brightness provision mode of the current application is set to window brightness, and determine the screen position of the current application after the flow. According to the application flow event, the window brightness corresponding to the current application in the display screen is set to display the current application and adjust the brightness change. This can realize that one vehicle system corresponds to multiple display screens and meet the brightness management needs of multiple display screens on the vehicle.

[0118] See also Figure 12 , step 15 includes:

[0119] 151: Determine the window brightness of the current application before the transfer;

[0120] 152: Add the window brightness corresponding to the current application to the first position in the sequence of the brightness set corresponding to the first display screen;

[0121] Brightness control methods include:

[0122] 191: Control the first display screen to display the current application at the brightness of the window at the top of the sequence corresponding to the brightness set.

[0123] The processor is used to determine the window brightness corresponding to the current application before the flow; add the window brightness corresponding to the current application to the first position of the sequence of the brightness set corresponding to the first display screen; and control the first display screen to display the current application with the window brightness at the first position of the sequence of the brightness set corresponding to the first display screen.

[0124] Each screen in the in-vehicle system of the present invention is provided with a corresponding brightness set that records window brightness information. The window brightness information in the brightness set can be arranged in chronological order to form a sequence. When the current application, whose brightness provision method is set to window brightness, is opened, closed, or transferred to another screen, upon monitoring the current application change or transfer event, the brightness set of the window brightness information of the transferred screen can be modified by determining the window brightness corresponding to the current application before the transfer, thereby displaying the window brightness of the current application on the transferred screen.

[0125] It can be understood that changes in the brightness attributes of the application window can trigger the native window brightness setting process. Therefore, when obtaining the brightness attributes of the application window after the flow, the screen position of the current application window after the flow can be determined, and the brightness set of the window brightness information of the screen after the flow can be modified.

[0126] For example, the first display screen is display screen 3, and the corresponding window brightness of the current application C before the flow is 70%. Then the window brightness of 70% of the current application C can be added to the first position of the brightness set sequence corresponding to the window brightness information of the display screen 3 after the flow, thereby controlling the first display screen 3 to display the current application with the window brightness of the first position of the corresponding brightness set sequence, so that after the current application C flows to the display screen 3, the current application C can be displayed on the display screen 3 with the window brightness of 70% of the current application C.

[0127] In this way, it can be ensured that after monitoring the current application flowing to the first display screen, the window brightness corresponding to the current application can be added to the first position of the sequence of the brightness set corresponding to the first display screen, and the first display screen can be controlled to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set, so that the current application can be displayed with the window brightness of the current application after flowing to the first display screen, that is, the set window brightness of the current application can take effect on the first display screen after the flow.

[0128] It should be noted that the present invention takes out the window brightness corresponding to the first position in the sequence of the brightness set corresponding to each screen, and sets the window brightness of the first position in the sequence to the corresponding screen, thereby realizing the setting of the window brightness of the application window of the current application in the screen after the flow, and realizing the exit of the window brightness of the application window of the current application in the screen before the flow.

[0129] See also Figure 13 , step 17 includes:

[0130] 171: Determine the window brightness of the current application before the transfer;

[0131] 172: Add the window brightness corresponding to the current application to the first position in the sequence of the brightness set corresponding to the second display screen;

[0132] Brightness control methods include:

[0133] 192: Control the second display screen to display the current application at the brightness of the window corresponding to the first one in the brightness set sequence.

[0134] The processor is used to determine the window brightness corresponding to the current application before the flow; add the window brightness corresponding to the current application to the first position of the sequence of the brightness set corresponding to the second display screen; and control the second display screen to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set.

[0135] For example, the second display screen is display screen 4, and the window brightness corresponding to the current application C before the flow is 70%, then the window brightness of 70% of the current application C can be added to the first position of the brightness set sequence corresponding to the window brightness information of the display screen 4 after the flow, thereby controlling the display screen 4 to display the current application with the window brightness corresponding to the first position of the brightness set sequence, so that after the current application C flows to the display screen 4, the current application C can be displayed on the display screen 4 with the window brightness of 70% of the current application C.

[0136] In this way, it can be ensured that after monitoring the current application flowing to the second display screen, the window brightness corresponding to the current application can be added to the first position of the sequence of the brightness set corresponding to the second display screen, and the second display screen can be controlled to display the current application with the window brightness at the first position of the sequence of the corresponding brightness set, so that the current application can be displayed with the window brightness of the current application after flowing to the second display screen, that is, the set window brightness of the current application can take effect on the second display screen after the flow.

[0137] In addition, if Figure 14 As shown, when the brightness provision method of the current application is set to the system brightness of the display, the automatic brightness in the current display system has only one main switch. After turning on the automatic brightness switch, all displays turn on the automatic brightness mode at the same time, and the automatic brightness adjustment of other displays can only be adjusted together with the automatic brightness of the main screen. Then, when the current application is displayed on one of the multiple displays, the system brightness of the display cannot be changed independently, so that when the current application flows on multiple displays, it is displayed with the same system brightness, which cannot meet the user's demand for the current application to be able to display with different system brightness changes on different displays.

[0138] In view of this, please see Figure 15 The present invention also provides a brightness control method for a vehicle-mounted system. The brightness control method includes:

[0139] 12: When the vehicle is driving, receiving a first control instruction for starting automatic brightness of the current application on the vehicle system;

[0140] 14: Determine the screen position of the current application;

[0141] 16: If the first display screen in the cockpit is currently used, turning on the automatic brightness main switch and the automatic brightness sub-switch corresponding to the first display screen according to the first control instruction to set the system brightness of the first display screen in the automatic brightness mode;

[0142] 18: If a second display screen is currently used in the cockpit, the automatic brightness main switch and the automatic brightness sub-switch corresponding to the second display screen are turned on according to the first control instruction to set the system brightness of the second display screen through the automatic brightness mode; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0143] The processor is used to receive a first control instruction to start automatic brightness of the current application on the vehicle system when the vehicle is driving; determine the screen position of the current application; if the current application is the first display screen in the cockpit, turn on the automatic brightness main switch and the automatic brightness sub-switch corresponding to the first display screen according to the first control instruction to set the system brightness of the first display screen through the automatic brightness mode; if the current application is the second display screen in the cockpit, turn on the automatic brightness main switch and the automatic brightness sub-switch corresponding to the second display screen according to the first control instruction to set the system brightness of the second display screen through the automatic brightness mode; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0144] That is, if Figure 16 As shown, in the automatic brightness display mode for multiple displays of the present invention, the automatic brightness switch can be divided into a main switch and multiple sub-switches, each sub-switch corresponding to a display. In other words, all displays in the multi-screen vehicle system can be equipped with an automatic brightness sub-switch for automatic brightness adjustment, making the automatic brightness adjustment method of the display more flexible.

[0145] First, when the vehicle is driving, a first control instruction for starting automatic brightness for the current application on the vehicle system is received. The first control instruction for the user to start automatic brightness can be the automatic brightness control button or area on any display screen in the multi-screen vehicle system pressed or touched by the user, or it can be a sliding gesture instruction set by the user on any display screen in the multi-screen vehicle system, such as a sliding gesture of any shape or number such as "L" shape or "mouth" shape. When the user makes the sliding gesture on any display screen, it can trigger the operation of starting the automatic brightness mode on the corresponding display screen. In addition, the operation of starting the automatic brightness mode by the user can also be other gesture actions set by the user, such as a gesture action of tapping the display screen 3 or more times with the knuckles of the fingers, which is not limited here.

[0146] It can be understood that the brightness of the current application at this time is provided in the system brightness.

[0147] Then, determine the screen location of the current application, such as Figure 16 As shown, if the first display screen currently used in the cockpit is display screen 2, the automatic brightness main switch and the automatic brightness sub-switch corresponding to display screen 2 are turned on according to the first control instruction to set the system brightness of display screen 2 through the automatic brightness mode, so that display screen 2 turns on the automatic brightness mode.

[0148] If the second display screen currently in use in the cockpit is display screen 3, the automatic brightness master switch and the automatic brightness sub-switch corresponding to display screen 3 are turned on according to the first control instruction to set the system brightness of display screen 3 in automatic brightness mode, so that display screen 3 is in automatic brightness mode. The system brightness of the first display screen and the system brightness of the second display screen are different, that is, the system brightness of display screen 2 and the system brightness of display screen 3 are different.

[0149] In this way, the user can turn on the automatic brightness mode for any one or more of the multiple display screens in the vehicle system, thereby meeting the user's demand for the current application whose brightness is provided by the system brightness to display different brightness changes at different system brightness on different display screens.

[0150] See also Figure 17 , brightness control methods include:

[0151] 19: When the vehicle is driving, receiving a second control instruction on the vehicle system to turn off automatic brightness of the current application;

[0152] 20: Determine the screen position of the current application;

[0153] 21: If the current application is on the first display screen, turn off the automatic brightness sub-switch corresponding to the first display screen according to the second control instruction to stop setting the system brightness of the first display screen through the automatic brightness mode;

[0154] 22: If the current application is on the second display screen, turn off the automatic brightness sub-switch corresponding to the second display screen according to the second control instruction to stop setting the system brightness of the second display screen through the automatic brightness mode; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0155] The processor is used to receive a second control instruction on the vehicle system to turn off automatic brightness of the current application when the vehicle is driving; determine the screen position of the current application; if the current application is on the first display screen, turn off the automatic brightness sub-switch corresponding to the first display screen according to the second control instruction to stop setting the system brightness of the first display screen through the automatic brightness mode; if the current application is on the second display screen, turn off the automatic brightness sub-switch corresponding to the second display screen according to the second control instruction to stop setting the system brightness of the second display screen through the automatic brightness mode; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0156] It is understandable that the second control instruction for turning off the automatic brightness mode by the user can be the same as the first control instruction for turning on the automatic brightness mode, except that the second control instruction is issued after the first control instruction. This is not further described here. In addition, the second control instruction for turning off the automatic brightness mode by the user can also be different from the first control instruction for turning on the automatic brightness mode by the user, and this is not limited here.

[0157] First, while the vehicle is driving, a second control instruction is received from the user to turn off the automatic brightness of the current application on the vehicle system.

[0158] Then, you can determine the screen location of the current application, such as Figure 16 As shown, if the current application is on the first display screen and the first display screen is display screen 1, the automatic brightness sub-switch corresponding to display screen 1 is turned off according to the second control instruction to stop setting the system brightness of display screen 1 through the automatic brightness mode, so that display screen 1 exits the automatic brightness mode.

[0159] If the current application is on the second display screen, and the second display screen is display screen 2, the automatic brightness sub-switch corresponding to display screen 2 is turned off according to the second control instruction, thereby stopping the system brightness setting of display screen 2 through the automatic brightness mode, causing display screen 2 to exit the automatic brightness mode. The system brightness of the first display screen and the system brightness of the second display screen are different, that is, the system brightness of display screen 1 and the system brightness of display screen 2 are different.

[0160] In this way, the user can exit the automatic brightness mode for any one or more of the multiple display screens in the vehicle system, thereby meeting the user's demand for the current application whose brightness is provided by system brightness to display brightness changes at different system brightness on different display screens.

[0161] See also Figure 18 , brightness control methods include:

[0162] 23: When the automatic brightness sub-switch corresponding to the first display and the automatic brightness sub-switch corresponding to the second display are both turned off, turn off the automatic brightness master switch to stop setting the system brightness of the first display and the system brightness of the second display through the automatic brightness mode.

[0163] The processor is used to turn off the automatic brightness main switch when the automatic brightness sub-switch corresponding to the first display and the automatic brightness sub-switch corresponding to the second display are both turned off, so as to stop setting the system brightness of the first display and the system brightness of the second display through the automatic brightness mode.

[0164] Specifically, when the user turns off the automatic brightness sub-switch for the first display, the multi-screen vehicle system can monitor that the automatic brightness sub-switch corresponding to the first display is turned off and then determine whether the automatic brightness sub-switches corresponding to all displays are turned off. If all automatic brightness sub-switches are turned off, the automatic brightness master switch can be turned off, and all displays will stop receiving automatic brightness reports.

[0165] That is, if both the automatic brightness sub-switch corresponding to the first display and the automatic brightness sub-switch corresponding to the second display are turned off, the main automatic brightness switch is turned off. It should be noted that the second display refers to any display in the vehicle system that can be adjusted in brightness via an app and is different from the first display. For example, the first display could be the driver's display in the vehicle cabin, and the second display could be the passenger display in the vehicle cabin.

[0166] If the automatic brightness sub-switch of the first display is off and the automatic brightness sub-switch of a second display among the other display screens is on, the automatic brightness master switch remains on and the automatic brightness setting reported to the first display screen is stopped.

[0167] In this way, when the automatic brightness sub-switches corresponding to multiple display screens are all turned off, the automatic brightness main switch can be automatically turned off, thereby reducing the energy loss of the multi-screen vehicle system.

[0168] The present invention further provides a non-volatile computer-readable storage medium containing a computer program. When the computer program is executed by one or more processors, the brightness control method described in any of the above embodiments is implemented.

[0169] For example, when the computer program is executed by a processor, the following steps of the brightness control method are implemented:

[0170] 01: When the vehicle is driving, receive the brightness setting instruction of the current application in the vehicle system to set the system brightness in the cabin;

[0171] 03: Determine the screen position of the current application;

[0172] 05: If the current application is the first display screen in the cockpit, adjust the system brightness of the first display screen according to the brightness setting instruction;

[0173] 07: If a second display screen is currently used in the cockpit, adjust the system brightness of the second display screen according to the brightness setting instruction; wherein the system brightness of the first display screen is different from the system brightness of the second display screen.

[0174] It is understood that a computer program includes computer program code. The computer program code may be in source code form, object code form, executable file, or some intermediate form. Computer-readable storage media may include any entity or device capable of carrying computer program code, recording media, USB flash drives, removable hard drives, magnetic disks, optical disks, computer memory, read-only memory (ROM), random access memory (RAM), and software distribution media.

[0175] The computer-readable storage medium of the present invention can apply the above-mentioned brightness control method without having to worry about which display screen the application is applied on. On multiple display screens, the brightness of the display screen where the application is currently located can be directly adjusted. After monitoring the flow of the application, there is no need to actively obtain the brightness of the current display screen. The target brightness information of the current display screen will be directly notified, so that the current display screen will directly make corresponding brightness value changes, which can meet the brightness management requirements of the display screen on the vehicle.
