[0038] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0039] With the development of automotive intelligence, integrating soft switches on the central control screen of the whole vehicle has become a subsequent trend. After the central control screen is integrated with the switch, it can be turned on by voice or gesture.

[0040] Automatic headlights mean that the headlights can automatically turn on when the vehicle enters a dark environment, and can automatically turn off when the vehicle is in a bright environment. Therefore, when the automatic headlights of the vehicle are turned on, if the vehicle is in a bright environment, the user cannot determine whether the automatic headlights are turned on successfully.

[0041] In order to avoid the vehicle's central control screen being unusable, a physical switch for controlling the automatic headlights can be added to the vehicle. When the vehicle includes both a soft switch and a physical switch for the automatic headlights, the user can use the soft switch interface to determine whether the automatic headlights are turned on successfully. When using both the physical switch and the central control screen's soft switch to control the lights, the physical switch and the soft switch need to work together.

[0042] Based on this, an embodiment of the present application provides a method for controlling vehicle lights, which can realize the control of vehicle lights based on the coordination of physical switches and soft switches of the central control screen.

[0043] The technical solution of the present application is described below through specific embodiments.

[0044] Reference Figure 1 , shows a schematic flow chart of a method for controlling a vehicle light provided in an embodiment of the present application, which may specifically include the following steps:

[0045] S101, if a signal indicating that the physical switch of the automatic headlight is triggered is received, a display instruction is sent to the vehicle central control device to instruct the vehicle central control device to display a preset headlight control interface on the display screen.

[0046] The execution subject in this embodiment may be a body domain controller, which may be connected to each headlight on the vehicle and control the turning on and off of each headlight.

[0047] Figure 2It is a schematic diagram of a physical switch provided in an embodiment of the present application. Figure 2 The physical switch in can be an automatic headlight on / off switch, that is, the user can turn on or off the automatic headlights by pressing this switch. When the automatic headlights are on, pressing the physical switch can turn off the automatic headlights; when the automatic headlights are off, pressing the physical switch can turn on the automatic headlights. The physical switch can avoid the failure of the central control screen. For example, when the central control screen is black or frozen, the user cannot use the lighting function of the central control screen. The physical switch can be used to turn the automatic headlights on or off. In this embodiment, the central control screen is the display screen of the vehicle's central control device.

[0048] The physical switch can be a self-resetting switch, that is, the switch will rebound after the user presses and releases it; the physical switch can also have a working indicator light, that is, when the automatic headlights of the vehicle are turned on, the working indicator light will light up, and when the automatic headlights are turned off, the working indicator light will go out.

[0049] The body domain controller can be connected to the physical switch via a hardwire. When the physical switch is pressed and bounces back to its original position, the body domain controller can receive a signal via a hardwire. In order to achieve linkage, when the physical switch is pressed, the light control interface needs to be displayed on the display screen of the vehicle's central control device. Therefore, when the body domain controller receives a signal that the physical switch is pressed, it can send a display instruction to the vehicle's central control device to instruct the vehicle's central control device to display a preset light control interface on the display screen.

[0050] After receiving the signal that the physical switch is pressed, the body domain controller can determine the control instruction corresponding to the signal. If the automatic headlights are currently in the on state, it can be determined that the control instruction is a control instruction to turn off the automatic headlights. At this time, the body domain controller can send a first display instruction to the vehicle central control device, and the first display instruction can instruct the vehicle central control device to display the control area corresponding to the automatic headlights in the headlight control interface with high brightness. If the automatic headlights are currently in the off state, it can be determined that the control instruction is a control instruction to turn on the automatic headlights. At this time, the body domain controller can send a second display instruction to the vehicle central control device, and the second display instruction can instruct the vehicle central control device to display the control area corresponding to the automatic headlights in the headlight control interface with low brightness.

[0051] When the physical switch is triggered, the vehicle central control device may or may not display the vehicle light control interface on its display screen. If the vehicle light control interface is not displayed, the vehicle central control device can directly call the corresponding interface; if the vehicle light control interface is displayed, the brightness of the automatic headlight control area can be directly adjusted.

[0052] In one possible implementation, the body domain controller can be connected to the vehicle central control device via the CAN bus. When the body domain controller receives a signal that the physical switch is triggered, it can send a CAN signal that the physical switch is pressed or popped up to the vehicle central control device via the CAN bus, so that the vehicle central control device can display the corresponding interface according to the received CAN signal. For example, when the body domain controller receives a signal that the physical switch is pressed, it can send 0x1 (Press) to the vehicle central control device; if the body domain controller receives a signal that the physical switch is released, it sends 0x0 (No Press) to the vehicle central control device. If the vehicle central control device receives 0x1 (Press), the light control interface on the display screen of the vehicle central control device can be popped up within T1 time to facilitate user operation.

[0053] The soft switches in the embodiment of the present application may be various control areas in the headlight control interface on the display screen of the vehicle's central control device. Figure 3 It is a schematic diagram of the vehicle light control interface provided in an embodiment of the present application. Figure 3 Figures ae in Figure 1 show the vehicle's headlight control interface in different states. Figure 3 In the car light control interface, the gray area is used to represent the area with high brightness, and the white area is used to represent the area with low brightness. Figure 3 As shown, the vehicle central control device integrates multiple functions of light off, position light on, low beam on, automatic headlight on, and rear fog light on. That is to say, the vehicle light control interface includes the soft switches of light off, position light on, low beam on, automatic headlight on, and rear fog light.

[0054] Among them, the functions of turning off the lights, turning on the position lights, turning on the low beam lights, and turning on the automatic headlights are mutually exclusive. To solve this mutual exclusive relationship, the soft switch in the vehicle's central control device can be controlled by a sliding solution, that is, only one area corresponding to the turning off the lights, turning on the position lights, turning on the low beam lights, and turning on the automatic headlights can be high brightness at the same time, and the other areas are low brightness.

[0055] Figure 3 a in the figure is the corresponding car light control interface for turning off the lights. At this time, the OFF switch button on the display screen is highlighted; the position light switch, low beam switch, and automatic headlight switch remain at low brightness. Figure 3 b in the figure is the car light control interface when the automatic headlights are on. At this time, the automatic headlight switch button on the display screen is highlighted; the OFF switch, low beam switch, and position light headlight switch remain at low brightness. Figure 3 The c in the figure is the vehicle light control interface when the position light is on. At this time, the position light switch button on the display screen is highlighted; the OFF switch, low beam switch, and automatic headlight switch remain at low brightness. Figure 3The d in the figure is the car light control interface when the low beam is on. At this time, the low beam switch button on the display screen is highlighted; the OFF switch, position light switch, and automatic headlight switch remain at a low brightness. The premise for turning on the rear fog light is that the low beam is on. Therefore, if the user chooses to turn on the rear fog light, the car light control interface can be as follows: Figure 3 As shown in e in the figure, the rear fog lamp is on and the low beam switch is bright; the OFF switch, position light switch and automatic headlight switch remain at low brightness.

[0056] In a possible implementation, when the vehicle central control device receives 0x1 (Press) from the body domain controller, it can determine whether the area corresponding to the automatic headlights in the current vehicle light control interface is high brightness or low brightness; if it is high brightness, it can be adjusted to low brightness; if it is low brightness, it can be adjusted to high brightness. For example, the current vehicle light control interface is as follows Figure 3 As shown in c, after receiving 0x1 (Press), the car light control interface can be switched to Figure 3 b in the figure; the current car light control interface is as follows Figure 3 As shown in b, after receiving 0x1 (Press), the car light control interface can be switched to Figure 3 a in.

[0057] S102, controlling the automatic headlights to respond to a signal from the physical switch.

[0058] When the physical switch is pressed, the body domain controller needs to determine whether the current signal is an on signal or an off signal based on the current state of the physical switch.

[0059] The body domain controller can determine the current state of the automatic headlights. In one possible implementation, the body domain controller can determine the current state of the automatic headlights by the indicator light of the physical switch of the automatic headlights. In another possible implementation, the body domain controller can also obtain the soft switch state displayed on the display screen of the vehicle's central control device to determine the current state of the automatic headlights. In another possible implementation, the automatic headlight function requires the support of the vehicle's photosensitive system. The body domain controller can request the current state of the vehicle's photosensitive system to determine whether the automatic headlight function is turned on. If the vehicle's photosensitive system is enabled, it means that the automatic headlight function is turned on; if the vehicle's photosensitive system is not enabled, it means that the automatic headlight function is turned off.

[0060] If the current state is the on state, the signal is determined to be an off signal, and the body domain controller can control the automatic headlight function to be turned off; if the current state is the off state, the signal is determined to be an on signal, and the body domain controller can control the automatic headlight function to be turned on.

[0061] In a possible implementation, the vehicle body domain controller may be connected to a driving unit of the automatic headlights, so that the turning on and off of the automatic headlights may be controlled by the driving unit.

[0062] S103, obtaining the state of the automatic headlight after responding to the signal of the physical switch.

[0063] After pressing the physical switch, the automatic headlights may respond to the signal of the physical switch successfully or unsuccessfully. Therefore, the body domain controller can obtain the status of the automatic headlights after responding to the signal of the physical switch in the same way as the previous step.

[0064] S104, sending the state of the automatic headlights to the vehicle central control device to instruct the vehicle central control device to synchronize the state of the automatic headlights on the vehicle light control interface according to the state.

[0065] The body domain controller can send the status of the automatic headlights to the vehicle central control device, and the vehicle central control device can synchronize the status of the automatic headlights on the headlight control interface.

[0066] After obtaining the status of the automatic headlights, the body domain controller can determine whether the control instruction corresponding to the physical switch is successfully executed based on the status of the automatic headlights. For example, if the control instruction is to turn on the automatic headlights, and the current status of the automatic headlights is on, it means that the status of the automatic headlights is consistent with the control instruction corresponding to the signal, and the control instruction corresponding to the physical switch is successfully executed, then the vehicle central control device can be instructed to maintain the current vehicle light control interface; if the control instruction is to turn off the automatic headlights, and the current status of the automatic headlights is off, it means that the status of the automatic headlights is consistent with the control instruction corresponding to the signal, and the control instruction corresponding to the physical switch is successfully executed, then the vehicle central control device can be instructed to maintain the current vehicle light control interface; if the control instruction is to turn on the automatic headlights, and the current status of the automatic headlights is on, it means that the status of the automatic headlights is consistent with the control instruction corresponding to the signal, and the control instruction corresponding to the physical switch is successfully executed. If the control command is executed successfully, the vehicle central control device can be instructed to maintain the current headlight control interface; if the control command is to turn on the automatic headlights, and the current state of the automatic headlights is on, it means that the state of the automatic headlights is inconsistent with the control command corresponding to the signal, and the control command corresponding to the physical switch fails to execute, then the vehicle central control device can be instructed to roll back the headlight control interface and switch the headlight control interface to the last displayed interface; if the control command is to turn off the automatic headlights, and the current state of the automatic headlights is on, it means that the state of the automatic headlights is inconsistent with the control command corresponding to the signal, and the control command corresponding to the physical switch fails to execute, then the vehicle central control device can be instructed to roll back the headlight control interface and switch the headlight control interface to the last displayed interface.

[0067] For example, when the automatic headlights are in the off state, the body domain controller detects a signal from the physical switch and can instruct the vehicle central control device to display the following information on the display screen: Figure 3 After the automatic headlights respond to the signal of the physical switch, if it is detected that the automatic headlights are turned on, the vehicle central control device can be instructed to maintain the following on the display screen: Figure 3 The vehicle light control interface shown in b in the figure; after the automatic headlights respond to the signal of the physical switch, if it is detected that the automatic headlights are in the off state, the vehicle central control device can be instructed to roll back the vehicle light control interface on the display screen. In a possible implementation, if the body domain controller receives a signal from the physical switch when the automatic headlights are turned off, the initial interface of the vehicle light control interface can be Figure 3 If the automatic headlights successfully respond to the signal of the physical switch, it means that the automatic headlights are turned on, and the headlight control interface can be changed to Figure 3 b in the figure; if the automatic headlights do not respond to the signal from the physical switch, it means that the automatic headlights are still off, and the headlight control interface can still be Figure 3 If the body domain controller receives a signal from the physical switch when the automatic headlights are turned on, the initial interface of the headlight control interface can be Figure 3 As shown in b in the figure; if the automatic headlights successfully respond to the signal of the physical switch, it means that the automatic headlights are turned off, and the headlight control interface can be changed to Figure 3 a in; if the automatic headlights do not respond to the signal of the physical switch, it means that the automatic headlights are still on, and the headlight control interface can still be Figure 3 b in.

[0068] In another possible implementation, if the body domain controller receives a signal from the physical switch when the automatic headlights are turned off, the headlight control interface can directly display Figure 3 b in the figure; if the automatic headlights successfully respond to the signal of the physical switch, it means that the automatic headlights are turned on, and the headlight control interface can continue to remain as Figure 3 b in the figure; if the automatic headlights do not respond to the signal of the physical switch, it means that the automatic headlights are still off, and the headlight control interface can be rebound to the previous display interface. If the body domain controller receives the signal of the physical switch when the automatic headlights are turned on, the headlight control interface can directly display Figure 3 a in the figure; if the automatic headlights successfully respond to the signal of the physical switch, it means that the automatic headlights are turned off, and the headlight control interface can continue to maintain Figure 3 a in the figure; if the automatic headlights do not respond to the signal from the physical switch, it means that the automatic headlights are still on, and the headlight control interface will return to the previous display interface.

[0069] The display screen of the vehicle central control device can display the vehicle light control interface within the first time after receiving the display command; within the second time, the body domain controller can return the status of the automatic headlights to the vehicle central control device. If the vehicle central control device does not receive the status of the automatic headlights within the second time, the vehicle central control device can continue to maintain the previous status.

[0070] In an embodiment of the present application, when the physical switch of the automatic headlights is triggered, the body domain controller can send a signal to the vehicle's central control device; and after the automatic headlights respond to the signal of the physical switch, the status of the automatic headlights is sent to the vehicle's central control device, so that the soft switch on the display screen of the vehicle's central control device can synchronize the current status of the headlights, thereby realizing the synchronization of the physical switch and the soft switch.

[0071] Reference Figure 4 , shows a schematic flow chart of another vehicle light control method provided by an embodiment of the present application, which may specifically include the following steps:

[0072] S401: If a signal indicating that the physical switch of the automatic headlight is triggered is received, a display instruction is sent to the vehicle central control device to instruct the vehicle central control device to display a preset headlight control interface on the display screen.

[0073] S402, controlling the automatic headlights to respond to the signal of the physical switch.

[0074] S403, obtaining the state of the automatic headlight after responding to the signal of the physical switch.

[0075] S404, sending the state of the automatic headlights to the vehicle central control device to instruct the vehicle central control device to synchronize the state of the automatic headlights on the vehicle light control interface according to the state.

[0076] S401 - S404 in this embodiment are similar to S101 - S104 in the previous embodiment, and they can be referenced to each other, and are not described in detail here.

[0077] S405: Acquire the soft switch state of the automatic headlights in the vehicle light control interface.

[0078] In the embodiment of the present application, the whole vehicle is equipped with both physical switches and soft switches, so it is necessary to solve the synchronization and priority problems between the physical switch and the soft switch. In the present embodiment, the physical switch and the soft switch adopt the post-trigger priority method, that is, the physical switch and the soft switch in the headlight control interface on the display screen of the headlight control device will respond to whichever is triggered later. For example, the user first turns on the position light through the display screen of the vehicle's central control device, and then the user physically presses the physical switch of the automatic headlight, then the vehicle will switch from the position light to the automatic headlight mode.

[0079] After a third preset time in response to the signal of the physical switch, the body domain controller can obtain the soft switch status on the display screen of the vehicle central control device.

[0080] S406: If the soft switch state does not match the current state of the automatic headlights within a preset time, control the vehicle to respond to the soft switch state of the automatic headlights.

[0081] Since the post-trigger is prioritized in this embodiment, after the preset time, if it is found that the soft switch state of the automatic headlights does not match the current state of the automatic headlights, it can be considered that after the physical switch is triggered, the control of the automatic headlights is triggered again by the soft switch. At this time, the vehicle can be controlled to respond to the soft switch state of the automatic headlights.

[0082] In a possible implementation, the vehicle body domain controller may receive a headlight central control signal for a target headlight sent by the vehicle central control device; switch the headlight state of the target headlight according to the headlight control signal; determine the current state of the target headlight after the headlight switching operation is performed; and return the current state to the vehicle central control device, which is used to synchronize the current state on the headlight control interface. The headlight central control signal may be equivalent to the soft switch state on the display screen of the vehicle central control device.

[0083] In this embodiment, the physical switch and the soft switch can implement priority judgment in a post-triggering priority manner, so that when the physical switch and the soft switch conflict, the state of the vehicle light is determined to avoid downtime caused by the conflict between the physical switch and the soft switch.

[0084] Reference Figure 5 , shows a schematic flow chart of a method for controlling a vehicle light provided in an embodiment of the present application, which may specifically include the following steps:

[0085] S501: If a display instruction is received from the vehicle body domain controller, a preset vehicle light control interface is displayed on the display screen.

[0086] The executor of this embodiment is the vehicle central control device. The vehicle central control device may have a display screen, and the display screen may display a headlight control interface. The headlight control interface may include multiple first control areas and second control areas, each of which may be used to represent a headlight state, and there is only one first control area displayed with high brightness on the headlight control interface at the same time; the second control area has an associated first control area, and when the second control area is displayed with high brightness, the first control area associated with the second control area is displayed with high brightness. Examples of headlight control interfaces may be as follows: Figure 3 Among them, OFF, position light, low beam light and automatic headlight can be the above-mentioned first control area; OFF and ON corresponding to fog light can be the second control area.

[0087] When the physical switch is triggered, the body domain controller can send a display instruction to the vehicle central control device. The display instruction can indicate that the physical switch of the automatic headlights is pressed, that is, the state of the automatic headlights needs to be changed. After receiving the display instruction, the vehicle central control device can determine the state of the automatic headlights in the current headlight control interface, and then display the soft switch state of the automatic headlights after the change on the display screen.

[0088] For example, when receiving the display command, the automatic headlights in the current car light control interface are not turned on; the user presses the physical switch, indicating that the automatic headlights will be turned on, and the automatic headlights turning on interface can be displayed on the display interface, that is, the display Figure 3 b in.

[0089] S502, in response to the status of the automatic headlights sent by the vehicle body domain controller, synchronizing the status of the automatic headlights on the vehicle headlight control interface.

[0090] The vehicle body domain controller will return the status of the automatic headlights within the second preset time. If the vehicle central control device receives the status of the automatic headlights within the second preset time, it can determine whether the automatic headlights respond to the physical switch signal successfully. If successful, the headlight control interface will continue to be maintained; if unsuccessful, the headlight control interface will be rebound to the previous state. If the vehicle central control device does not receive the status of the automatic headlights within the second preset time, the headlight control interface can also be rebound to the previous state.

[0091] In another possible implementation, the vehicle central control device may directly display the current headlight control interface; and update the headlight control interface after receiving the status of the automatic headlights.

[0092] In an embodiment of the present application, the vehicle's central control device can determine whether the physical switch is triggered and whether the automatic headlights successfully respond to the physical switch through the body domain control system, so that the status of the automatic headlights can be synchronized on the display screen, so that the status of the physical switch, the vehicle's central control device and the headlights are synchronized, making it convenient for the user to determine the status of the headlights and perform operations.

[0093] Reference Figure 6 , shows a schematic flow chart of another vehicle light control method provided by an embodiment of the present application, which may specifically include the following steps:

[0094] S601: If a display instruction is received from the vehicle body domain controller, a preset vehicle light control interface is displayed on the display screen.

[0095] S602, in response to the status of the automatic headlights sent by the vehicle body domain controller, synchronizing the status of the automatic headlights on the vehicle headlight control interface.

[0096] S601 - S602 in this embodiment are similar to S501 - S502 in the previous embodiment, and they can be referenced to each other, and are not described in detail here.

[0097] S603: Identify control instructions for the target vehicle lights.

[0098] Users can issue control commands for the lights on the display screen in a variety of ways. For example, users can control the lights by voice, gestures, or touch screen. The vehicle central control device can identify the control commands currently issued by the user based on pre-stored data. For example, the light control interface may include a slider, and the user can slide directly on the display screen interface so that the slider can stay in different control areas. The user's control command for the lights can be determined based on the control area where the slider finally stays.

[0099] S604: Displaying a control area corresponding to the control instruction with high brightness on the vehicle light control interface.

[0100] After the vehicle central control device recognizes the control command for the target headlight, it can synchronize the control command on the headlight control interface, that is, it can highlight the control area corresponding to the control command. For example, the vehicle's position lights are turned on, that is, the headlight control interface can be as follows Figure 3 As shown in c in FIG. 1 , the user can send a control command by voice "turn on the low beam"; after the control command is recognized, the area corresponding to the position light can be displayed at a low brightness, and then the area corresponding to the low beam can be displayed at a high brightness.

[0101] S605: Send a vehicle light central control signal to the vehicle body domain controller according to the control instruction.

[0102] The vehicle central control device needs to respond to the control command for the headlights through the body domain control system, so the vehicle central control device can return the headlight central control signal to the body domain controller. The headlight central control signal can include the corresponding headlight status, such as automatic headlight on, low beam on, light off or fog light on.

[0103] S606, receiving the current state of the target headlight after responding to the headlight central control signal, which is returned by the body domain controller.

[0104] After receiving the central control signal of the lights, the body domain controller can determine the corresponding target lights; then switch the state of the target lights according to the central control signal of the lights. For example, the vehicle may include the first and second lights. When the position lights are turned on, the first lights are on and the second lights are off; when the low beam lights are turned on, both the first and second lights are on. When the central control signal of the lights is that the position lights are turned on, the target lights can be determined to be the first lights, and then the first lights are turned on; when the central control signal of the lights is that the low beam lights are turned on, the target lights can be determined to be the first lights and the second lights, and then the first and second lights are turned on.

[0105] After switching the light status, the body domain control system can return the current status of the light to the vehicle central control device so as to synchronize the light status on the light control interface.

[0106] In a possible implementation, since the position lights, low beam lights and fog lights have only soft switches, when the light control signal is a position light, low beam light and fog light signal, the body domain control system may not return the light status to the vehicle central control device. However, the status of the automatic headlights can be controlled by both physical switches and soft switches, so the body domain control system needs to return the automatic headlight status.

[0107] S607, synchronizing the current state of the target headlight on the headlight control interface.

[0108] If the target headlight is an automatic headlight, the vehicle central control device may synchronize the current state of the automatic headlight on the headlight control interface after receiving the current state of the target headlight. If the target headlight is not an automatic headlight, the vehicle central control device may not perform steps S606 and S607.

[0109] In this embodiment, the user can conveniently and quickly control the lights in a variety of ways based on the soft switch integrated in the vehicle central control device, thus realizing intelligent control of the lights; at the same time, the physical switch ensures that the lights can still be operated when the display screen of the vehicle central control device fails. In addition, based on the method in this embodiment, the linkage of the physical switch and the soft switch can be realized.

[0110] It should be noted that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0111] Figure 7 Schematic diagram of a vehicle light control system provided by an embodiment of the present application. Figure 7 As shown in the figure, in the vehicle light control system, the body domain controller can be connected to the central control screen, the automatic headlight physical switch, the headlights, and the taillights respectively. The central control screen can be used to represent the vehicle central control device and its display screen.

[0112] The body domain controller is connected to the headlights and taillights, so it can control the lighting and extinguishing of the headlights and taillights, thereby realizing the control of the car lights.

[0113] The body domain controller is connected to the physical switch and can receive control instructions issued by the user through the physical switch. Based on the control instructions, the body domain controller can control the headlights and / or taillights to respond to the control instructions; on the other hand, it can send the control instructions to the central control screen so that the central control screen can synchronously display the corresponding car light control interface.

[0114] The body domain controller is connected to the central control screen and can receive control instructions for the lights triggered by the user through the soft switch of the central control screen. Based on the control instruction, the body domain controller can control the headlights and / or taillights to respond to the control instruction.

[0115] In a possible implementation, the headlights in the vehicle are composed of multiple modules, and each headlight control instruction corresponds to one or more different headlight modules. After receiving the control instruction from the physical switch or the central control screen, the body domain control system can determine the headlight module corresponding to the control instruction, and then light up the corresponding headlight module.

[0116] The body domain controller can be the lighting logic processing unit on the vehicle, and the physical switch of the automatic headlights is connected to the body domain controller through a hard wire. The lighting logic processing unit can send the status of whether the physical switch is pressed to the central control screen through the CAN bus signal. The CAN bus signal indicates whether the physical switch is pressed. If the physical switch is pressed, the CAN bus signal can be 0x1 (Press). If the physical switch is released, the CAN bus signal can be 0x0 (NoPress). If the central control screen receives 0x1 (Press), the lighting switch adjustment interface in the central control screen needs to be popped up within T1 time for user operation.

[0117] The body domain controller also needs a CAN bus signal to send the status of whether to enter or exit the automatic headlights to the central control screen. If the user operates the soft switch or physical switch in the light control interface to turn on the automatic headlights, the body domain controller sends the automatic headlight status 0x1 (Autolamp); if the user operates the soft switch or physical switch in the light control interface to turn off the automatic headlights, the body domain controller sends the automatic headlight status 0x0 (No Autolamp). When the user turns on the automatic headlights through the central control screen, the central control screen will determine whether the vehicle has entered the automatic headlight mode. If not, the software switch will rebound to the previous state. Therefore, each time the user uses the central control screen to turn on the automatic headlights, it is necessary to wait for a period of time T1 before judging the automatic headlight status sent by the body domain controller. If after T2, the body domain controller has not sent the automatic headlight 0x1 (Autolamp), it will return to the previous state; similarly, if the user operates the physical switch, the body domain controller also needs to wait for the synchronization of the soft switch on the light control interface. After the user operates the physical switch, the body domain controller needs to send the automatic headlight 0x1 (Autolamp) to the central control screen. At this time, it is necessary to wait for a period of time T3 to judge the status of the soft switch on the light control interface. If after T3, the soft switch on the light control interface is not consistent with the current status of the automatic headlight, then the vehicle can respond to the light switch request on the light control interface of the current central control screen.
