Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the development and progress of automobile technology, a large number of vehicle-mounted display devices are arranged on an automobile so as to display driving information of the automobile for a driver in real time and provide entertainment interaction services for passengers. The vehicle-mounted display device mainly comprises an instrument panel and a copilot screen of a vehicle. It is worth noting that when the vehicle was gone in the environment that light is relatively weak, because the luminance of on-vehicle display screen is higher than the luminance of carriage external environment, the light that leads to sending of on-vehicle display screen can reflect on window glass to form "reflection virtual image" on window glass, when the vehicle turned to or when operations such as doubling, this reflection virtual image made the driver can't observe the rear-view mirror with clearing away, and then influenced driving safety.
At present, the brightness of the vehicle-mounted display screen is mainly controlled by manual adjustment of a driver, however, when the driver utilizes the manual adjustment, the attention of the driver to drive the vehicle is easily dispersed, and the driving safety hazard exists.
In order to solve the above problem, the inventor has made a long-term study, and proposes a method for controlling an on-vehicle display screen according to an embodiment of the present application, which determines whether a driving control signal for controlling a change of a current driving state of a vehicle is acquired when it is detected that ambient light around the vehicle is lower than a preset threshold; if the driving control signal is acquired, the screen brightness value of the vehicle-mounted display screen is adjusted to the target brightness value, so that the brightness of the vehicle-mounted display screen is automatically adjusted according to the driving operation of a driver, a reflection virtual image is prevented from being generated, and the driver can conveniently observe the rearview mirror.
An application scenario of the vehicle-mounted display screen control method related to the present application is introduced below.
As shown in fig. 1, the in-vehicle display screen control scene shown in fig. 1 includes a vehicle driver side mirror 501, a passenger side mirror 507, an instrument panel display 502, a passenger side display 505, a steering wheel 503, and a hand piece 504, as an embodiment. When the vehicle is driven in the environment that light is weak such as dark, the light that panel board display screen 502 and vice driving display screen 505 produced can reflect respectively and form the reflection virtual image on the window glass of corresponding side to influence the driver and observe the rear-view mirror. For example, the reflected light of the secondary display screen 505 creates a virtual image 506 on the secondary side window glass, the virtual image 506 being capable of blocking the driver from viewing the secondary side rearview mirror 507 through the window glass.
Alternatively, when the headlights of the vehicle are turned on, the luminance values of the dashboard display 502 and the front passenger display 505 may be controlled by the driving control signals generated by the steering wheel 503 and the hand catch 504, so as to avoid the generation of a virtual image. As one of the vehicle gear position control devices, the hand gear 504 may be replaced with a ground gear, which is not limited herein. It should be noted that the driving seat shown in fig. 1 is disposed on the left side of the interior of the vehicle, fig. 1 is only an embodiment, and the right-driving-seat vehicle model also belongs to the protection scope of the present application when used in the method of the embodiment of the present application. Embodiments in the present application will be described in detail below with reference to the accompanying drawings.
As shown in fig. 2, fig. 2 schematically illustrates an in-vehicle display screen control method provided in an embodiment of the present application, and the in-vehicle display screen control method 100 may include the following steps S110 to S120.
S110: and when the ambient light around the vehicle is detected to be lower than a preset threshold value, judging whether a running control signal is acquired.
When the vehicle is driven in a dark environment (such as night and a tunnel), because light inside and outside a carriage has a certain light difference value, virtual images derived from the vehicle-mounted display screen can be generated on the window glass. For this, the brightness value of the on-vehicle display screen may be adjusted to eliminate the virtual image according to a driving control signal of the vehicle when it is detected that the ambient light around the vehicle is lower than a preset threshold value.
In the embodiment of the application, the running control signal is used for controlling and changing the current running state of the vehicle, wherein the running state can be the direction and the speed of the vehicle. The driving control signal may include at least one of a control signal of a steering wheel of the vehicle and a control signal of a gear of the vehicle. As an embodiment, the preset threshold is determined by experiments when the vehicle is produced, and may also be adjusted according to the actual use area of the vehicle and the habit of the driver.
In some embodiments, the driving control signal may be specifically used for controlling changing of the current driving direction of the vehicle. If the vehicle is moving forward and straight ahead, when the vehicle is turning left at present, the vehicle can be considered to receive the running control signal, and if the vehicle is moving forward at present, when the vehicle is moving backward at present, the vehicle can also be considered to receive the running control signal.
As an embodiment, the driving control signal may specifically be a control signal of a steering wheel of the vehicle, since the steering wheel may control to change the current driving direction of the vehicle to driving to the right or to the left. Specifically, the driver may generate a steering wheel control signal if the steering wheel is turned while driving.
As another embodiment, since reversing may control changing the current driving direction of the vehicle to backward driving, the driving control signal may specifically be a control signal of a vehicle gear. Specifically, during driving, if the driver shifts the gear of the vehicle to the reverse gear, a vehicle gear control signal may be generated.
In other embodiments, the travel control signal may be specifically for controlling a change in the current travel speed of the vehicle. As an embodiment, the running control signal may be a vehicle accelerator control signal, because an accelerator pedal of a fuel automobile may control and change a current running speed of the vehicle. Specifically, the driver may generate a vehicle throttle control signal if the driving speed is changed by the throttle pedal during driving. As another embodiment, the travel control signal may be a vehicle braking control signal, since the braking device of the vehicle may control the current travel speed of the vehicle. Specifically, the driver may generate a vehicle braking control signal if braking is performed via the brake pedal while driving.
In some embodiments, the vehicle may use whether it is detected that the ambient light around the vehicle is lower than a preset threshold as a trigger condition for performing an operation of adjusting the brightness of the on-vehicle display screen, and when it is detected that the ambient light around the vehicle is lower than the preset threshold, it may be determined whether a driving control signal of the vehicle is acquired, so as to adjust the brightness value of the on-vehicle display screen according to the driving control signal. As an embodiment, when the vehicle detects that the ambient light around the vehicle is lower than a preset threshold, whether the running control signal of the vehicle is acquired may be determined in real time or periodically, for example, when the ambient light around the vehicle is detected to be lower than the preset threshold, whether at least one of the control signal of the steering wheel and the control signal of the gear is acquired may be determined at fixed time intervals.
S120: and if the driving control signal is acquired, adjusting the screen brightness value of the vehicle-mounted display screen to a target brightness value.
The target brightness value is a brightness value to which the vehicle-mounted display screen needs to be adjusted, and is noteworthy that the target brightness value can be measured by a brightness test according to different vehicle types in the automobile production process of an automobile manufacturer. When the brightness of the vehicle-mounted display screen is actually adjusted, the brightness can be adjusted according to target brightness values corresponding to different vehicle systems. In the embodiment of the application, after the vehicle determines whether the driving control signal is acquired, whether the screen brightness value of the vehicle-mounted display screen is adjusted or not can be determined according to the determination result. Specifically, if the driving control signal of the vehicle is acquired, the screen brightness value of the vehicle-mounted display screen may be adjusted to the target brightness value according to the driving control signal. In some embodiments, if the driving control signal of the vehicle is not acquired, the brightness value of the on-board display screen may not be adjusted.
In some embodiments, if the driving control signal of the vehicle is not acquired, other processing operations may be performed. In one embodiment, when the vehicle does not acquire the running control signal, the driver may be prompted through a display screen or voice whether to adjust the brightness value of the on-board display screen.
In the embodiment of the application, when it is detected that the ambient light around the vehicle is lower than a preset threshold value, whether a driving control signal is acquired is judged, wherein the driving control signal is used for controlling and changing the current driving state of the vehicle; and if the driving control signal is acquired, adjusting the screen brightness value of the vehicle-mounted display screen to a target brightness value. Therefore, the brightness value adjustment of the vehicle-mounted display screen is combined with the running control signal of the vehicle, so that the brightness of the vehicle-mounted display screen can be adjusted according to the driving operation of a driver, the reflection influence of the reflected light of the vehicle-mounted display screen on the window glass is reduced, the driver can conveniently observe the rearview mirror of the vehicle, and the driving safety is greatly improved.
As shown in fig. 3, fig. 3 schematically illustrates an in-vehicle display screen control method provided in an embodiment of the present application, and the in-vehicle display screen control method 200 may include the following steps S210 to S230.
S210: when it is detected that ambient light around a vehicle is lower than a preset threshold value, steering wheel rotation information of the vehicle is acquired, wherein the steering wheel rotation information comprises a steering wheel rotation direction and a steering wheel rotation angle.
In driving a vehicle, a driver sometimes needs to perform steering or merging operations, and for this reason, driving safety needs to be ensured by observing a rear view mirror. When the ambient light around the vehicle is lower than the preset threshold value, whether the vehicle acquires a steering wheel control signal or not can be judged through the steering wheel rotation information of the vehicle, and then the brightness of the vehicle-mounted display screen is adjusted to ensure that a driver can clearly observe the rearview mirror. The control signal of the vehicle steering wheel represents a control signal when the steering wheel rotates to control the running direction of the vehicle to change when the vehicle turns or is in parallel.
In the embodiment of the present application, the travel control signal may be a steering wheel control signal of the vehicle, which is determined when the steering wheel is rotated to satisfy a preset condition. Specifically, for example, when the ambient light around the vehicle is acquired during night driving of the vehicle, it may be detected by a Body Control Module (BCM) that the ambient light is lower than a preset threshold value based on the acquired photometric value of the ambient light around the vehicle, and further, when the driver turns, the steering wheel may be rotated to generate a physical electrical signal, so that whether the electrical signal is acquired may be periodically determined by the BCM at set time intervals, thereby determining whether the steering wheel Control signal is acquired.
In some implementations, when it is detected that the ambient light around the vehicle is below a preset threshold, the steering wheel rotation direction and the steering wheel rotation angle of the vehicle may be acquired simultaneously. As an embodiment, when it is detected that the ambient light around the vehicle is lower than a preset threshold, the steering wheel rotation direction and the steering wheel rotation angle of the vehicle may be periodically acquired. For example, when the Vehicle detects that the ambient light around the Vehicle is lower than the preset threshold while the Vehicle is running, the rotation direction and the rotation angle of the steering wheel of the Vehicle can be acquired by a (Vehicle Control Unit, VCU) in the same time interval. Specifically, with the steering wheel return position as the reference position, at this time, the rotation angle of the steering wheel can be set to zero degrees. When the steering wheel is rotated clockwise by an angle a from the reference position, the angle a may be used as the rotation angle of the steering wheel. Similarly, when the steering wheel is rotated counterclockwise by B degrees from the reference position, the B degrees can be regarded as the rotation angles of the steering wheel rotated counterclockwise.
S220 a: and if the rotating direction of the steering wheel is clockwise and the rotating angle of the steering wheel is greater than a first preset angle, determining to acquire a first control signal.
In the embodiment of the application, the specific control signal of the steering wheel can be determined through the acquired rotating direction and rotating angle of the steering wheel so as to adjust the brightness values of different vehicle-mounted display screens. The first preset angle is a preset angle of the steering wheel rotating clockwise. The first control signal is a steering wheel control signal, namely a driving control signal, which meets the requirement of adjusting the brightness of the vehicle-mounted display screen when the steering wheel of the vehicle rotates clockwise. In some embodiments, when the steering wheel rotation information of the vehicle is acquired, the rotation angle and the rotation direction of the steering wheel of the vehicle can be determined, and further, the corresponding control signal is determined according to the rotation angle and the rotation direction.
As an embodiment, when it is determined that the rotation direction of the steering wheel of the vehicle is clockwise and the rotation angle is greater than a preset angle, it may be determined that the vehicle has acquired the first control signal. For example, when the driver turns right, and determines that the steering wheel of the vehicle is turned clockwise and the clockwise rotation angle is greater than 30 degrees, it can be determined that the first control signal is acquired.
S230 a: and if the first control signal is acquired, adjusting the screen brightness value of the copilot display screen to a target brightness value.
In the embodiment of the present application, when the steering wheel of the vehicle is rotated clockwise, it can be inferred that the driver will observe the rear mirror on the passenger side, and therefore, it is necessary to adjust the brightness of the passenger display screen to eliminate the virtual image on the window glass on the passenger side. As an embodiment, when it is detected that the steering wheel of the vehicle rotates clockwise and the clockwise rotation angle is greater than a preset angle, it may be determined that the first control signal is acquired, and then the screen brightness value of the secondary driving display screen may be adjusted to a target brightness value.
For example, when a vehicle travels to an intersection at night, the driver needs to turn right to enter another road. When a driver rotates a steering wheel clockwise, the vehicle acquires steering wheel rotation information, and judges that the rotation direction of the steering wheel is clockwise and the rotation angle is larger than 30 degrees, so that the first control signal is determined to be acquired, and the screen brightness value of the copilot display screen is adjusted to be the target brightness value.
S220 b: and if the rotating direction of the steering wheel is the anticlockwise direction and the rotating angle of the steering wheel is larger than a second preset angle, determining to acquire a second control signal.
The second preset angle is a preset angle of the steering wheel rotating in the anticlockwise direction. The second control signal is a steering wheel control signal, namely a driving control signal, which meets the requirement of adjusting the brightness of the vehicle-mounted display screen when the steering wheel of the vehicle rotates anticlockwise. As an embodiment, when it is determined that the rotation direction of the steering wheel of the vehicle is counterclockwise and the rotation angle is greater than a preset angle, it may be determined that the vehicle has acquired the second control signal. For example, when the driver turns left and determines that the steering wheel of the vehicle is counterclockwise and the rotation angle is greater than 30 degrees, it may be determined that the second control signal is acquired.
S230 b: and if the second control signal is acquired, adjusting the screen brightness value of the display screen of the instrument panel to a target brightness value.
When the vehicle was gone at night, the panel board display screen of vehicle can be with reflection light reflection to the window glass of driving side on, and then form the virtual image. As an embodiment, after it is determined that the second control signal is acquired, the screen brightness value of the dashboard display screen may be adjusted to the target brightness value, specifically refer to step S230 a.
In the embodiment of the application, when the ambient light around the vehicle is detected to be lower than a preset threshold value, the steering wheel rotation information of the vehicle is acquired; if the rotating direction of the steering wheel is clockwise and the rotating angle of the steering wheel is larger than a first preset angle, determining to acquire a first control signal, and adjusting the screen brightness value of the pilot display screen to a target brightness value; and if the rotating direction of the steering wheel is anticlockwise and the rotating angle of the steering wheel is larger than a second preset angle, determining to acquire a second control signal, and adjusting the screen brightness value of the display screen of the instrument panel to a target brightness value. Therefore, the brightness of different vehicle-mounted display screens is adjusted according to different steering requirements of a driver, the reflection influence of the reflection light of the vehicle-mounted display screens on the window glass is reduced, the driver can observe the rearview mirror of the vehicle conveniently, and the driving safety is greatly improved.
As shown in fig. 4, fig. 4 schematically illustrates an in-vehicle display screen control method provided in an embodiment of the present application, and the in-vehicle display screen control method 300 may include the following steps S310 to S330.
S310: when the fact that the ambient light around the vehicle is lower than a preset threshold value is detected, whether the driving gear of the vehicle is in a reverse gear or not is judged.
In addition to steering or merging operations, a driver also has an operation of backing up while driving the vehicle. For this purpose, it is necessary to ensure the safety of reversing by looking at the rear view mirror. In the embodiment of the application, when the ambient light around the vehicle is lower than the preset threshold, whether the running gear of the vehicle is in the reverse gear or not can be judged. Specifically, when the hand gear of the vehicle is shifted, the whole vehicle control unit VCU of the vehicle can calculate according to the detected voltage signal of the hand gear shift lever, so as to determine a specific gear, and adjust the brightness of the vehicle-mounted display screen if the gear is a reverse gear.
As an embodiment, when it is detected that the ambient light around the vehicle is lower than a preset threshold, it may be determined whether the vehicle is in a reverse gear at that time. For example, after the electric vehicle detects that ambient light around the vehicle is lower than a preset threshold, it is detected in real time whether a wye shift lever of the electric vehicle shifts to an R-gear, specifically, when the vehicle detects that the ambient light around the vehicle is lower than the preset threshold during night driving, when a driver sets a gear of the vehicle to the R-gear through the wye shift, a corresponding voltage signal is generated at the R-gear position of the wye shift, and then the voltage signal may be communicated and interacted with a VCU through a Controller Area Network (CAN), so that the VCU determines that the gear of the vehicle is the R-gear, and further, may determine that a gear control signal of the vehicle is acquired.
S320: and if the driving gear of the vehicle is in reverse gear, determining to acquire the gear control signal, wherein the gear control signal is the driving control signal.
The control signal of the vehicle gear represents a control signal when the gear of the vehicle is in a reverse gear. In some embodiments, when it is detected that the ambient light around the vehicle is lower than the preset threshold, it may be determined that the vehicle is in reverse gear at this time, and it is determined that the gear control signal of the vehicle is acquired. As an embodiment, when it is detected that the running range of the vehicle is in the reverse range, it may be determined that the range signal of the vehicle is acquired. For example, the VCU of the vehicle acquires and analyzes voltage information of the hand-in-gear lever, determines that the R-range of the hand-in-gear has a voltage signal, and further determines that the gear control signal is acquired.
S330: and if the driving control signal is acquired, adjusting the screen brightness value of the vehicle-mounted display screen to a target brightness value.
In the embodiment of the application, when the driving control signal of the vehicle is acquired, the screen brightness value of the vehicle-mounted display screen can be adjusted to the target brightness value, so that a driver can conveniently observe the rearview mirror to back the vehicle. In some embodiments, after the driving control signal is obtained, the screen brightness value of the vehicle-mounted display screen may be adjusted to the target brightness value according to the driving control signal, and it is noted that, when the vehicle is in a reverse mode, the brightness adjustment may be performed on the dashboard display screen and the assistant driving display screen at the same time. Specifically, referring to fig. 5, step S330 may include:
s331: and acquiring the current brightness value of the vehicle-mounted display screen.
Because the intensity difference of the inside and outside light of carriage just can produce the reflection virtual image on window glass when reaching certain difference, consequently, the vehicle can carry out reasonable adjustment or do not adjust according to the luminance value of current on-vehicle display screen when the luminance value of adjustment on-vehicle display screen.
In one embodiment, when the driving control signal of the vehicle is acquired, the current brightness value of the on-board display screen of the vehicle may be acquired. For example, when the driving control signal is acquired, the current brightness value of the vehicle-mounted display screen at that time may be acquired: alpha nit and stores the current luminance value a nit for subsequent comparison.
S332: and judging whether the current brightness value is larger than a target brightness value or not.
At the target brightness value, the reflected light of the vehicle-mounted display screen does not generate a virtual image on the window glass. The target brightness value can be adaptively switched according to the environment of the vehicle. For example, at night, the target brightness value may be E nit, and at evening or on dark weather, the target brightness value may be F nit (E ≠ F).
As an embodiment, the stored current brightness value α nit may be compared with the target brightness β nit to determine whether the current brightness value is greater than the target brightness value.
S333: and if the current brightness value is larger than the target brightness value, adjusting the brightness value of the vehicle-mounted display screen to the target brightness value.
In one embodiment, when the current brightness value α nit is determined to be greater than the target brightness β nit, the current brightness value α of the vehicle-mounted display screen is adjusted to the target brightness β. Specifically, the adjustment is performed according to respective target brightness values respectively according to respective current brightness values of an instrument panel display screen and a copilot display screen of the vehicle.
Referring to fig. 6 by way of example, fig. 6 is a flowchart illustrating a method for controlling an on-board display screen according to an embodiment of the present application, where when a vehicle is running in a dark environment, it is detected that ambient light around the vehicle is lower than a preset threshold, at this time, steering wheel rotation information of the vehicle and gear position information of the vehicle may be acquired, and further, whether to adjust screen brightness of the on-board display screen may be determined according to the acquired steering wheel rotation information of the vehicle and the gear position information of the vehicle.
Specifically, when it is detected that the ambient light around the vehicle is lower than a preset threshold, the steering wheel rotation information and the shift position information of the vehicle can be acquired in real time. When the steering wheel rotation information of the vehicle is acquired, whether the steering wheel rotation information meets a preset rotation condition or not is judged, if the steering wheel rotation information meets the preset rotation condition, a steering wheel control signal is determined to be acquired, so that the screen brightness value of the vehicle-mounted display screen is adjusted to a target brightness value according to the steering wheel control signal, wherein the brightness of an instrument panel display screen or a secondary driving display screen can be adjusted according to the specific steering wheel control signal. Specifically, when the steering wheel control signal of the vehicle is to control the vehicle to turn left, the brightness value of the dashboard display screen can be adjusted, and when the steering wheel control signal of the vehicle is to control the vehicle to turn right, the brightness value of the secondary driving display screen can be adjusted. In addition, when the gear information of the vehicle is acquired, whether the gear is in reverse gear or not is judged, and if the driving gear of the vehicle is in reverse gear, the gear control signal is determined to be acquired, so that the screen brightness value of the vehicle-mounted display screen is adjusted to the target brightness value, wherein the screen brightness values of the dashboard display screen and the assistant driver display screen can be adjusted to the target brightness value at the same time.
In the embodiment of the application, when it is detected that the ambient light around the vehicle is lower than a preset threshold value, whether the running gear of the vehicle is in a reverse gear or not is judged; and if the driving gear of the vehicle is in reverse gear, determining the acquired gear control signal as a driving control signal, and further adjusting the screen brightness value of the vehicle-mounted display screen to a target brightness value. Therefore, the brightness of the vehicle-mounted display screen is adjusted according to the operation of the driver for reversing the gear, and the reflection influence of the reflected light of the vehicle-mounted display screen on the window glass is reduced, so that the driver can observe the rearview mirror of the vehicle conveniently, and the reversing safety is greatly improved.
As shown in fig. 7, fig. 7 schematically illustrates an in-vehicle display screen control method provided in an embodiment of the present application, and the in-vehicle display screen control method 400 may include the following steps S510 to S430.
S410: when the fact that the ambient light around the vehicle is lower than a preset threshold value is detected, whether a running control signal is acquired or not is judged, and the running control signal is used for controlling and changing the current running state of the vehicle.
When the vehicle is running and in a dark environment, the driver can turn on the headlamp of the vehicle to judge the running road condition in front of the vehicle. Therefore, in some embodiments, it may be determined that the ambient light around the vehicle is detected to be lower than the preset threshold value when it is determined that the headlights of the vehicle are turned on as a condition for determining that the vehicle is running in a dark environment. Further, it is determined whether or not the travel control signal is acquired.
S420: and if the driving control signal is acquired, adjusting the screen brightness value of the vehicle-mounted display screen to a target brightness value.
In the embodiment of the present application, the content in the foregoing embodiment can be referred to for the specific description of steps S410 and S420, and is not described herein again.
S430: and if the driving control signal is not obtained again within the preset time, restoring the brightness value of the vehicle-mounted display screen to the brightness value before adjustment.
The preset time is a preset timing time period for reacquiring the driving control signal, and the timing time period can be correspondingly set according to the models of different vehicles. By setting the preset time, whether the driving control signal is acquired again or not can be detected within the preset time, so that whether the brightness value of the vehicle-mounted display screen is restored to the brightness value before adjustment or not is judged. As an embodiment, the preset time may be set using a watchdog timer. After the screen brightness value of the vehicle-mounted display screen is adjusted to the target brightness value, the screen brightness value of the vehicle-mounted display screen can be restored under the condition that a driver does not observe a rearview mirror, and therefore the vehicle-mounted display screen can be conveniently watched by passengers. In some embodiments, after the brightness value of the on-board display screen is adjusted, if the driving control signal of the vehicle is not acquired again within the preset time, the brightness value of the on-board display screen may be restored.
As an embodiment, after the brightness value of the on-board display is adjusted, whether the driving control signal of the vehicle is received or not may be determined within a preset time, and if the driving control signal of the vehicle is not received again, the brightness value of the on-board display may be restored to the brightness value before the adjustment. For example, when the driver performs a right turn operation, the vehicle determines to acquire a steering wheel control signal according to the driver's right turn operation on the steering wheel, and then adjusts the brightness value of the secondary driving display screen, specifically, if the brightness of the secondary driving display screen is higher than a target brightness value at this time, the brightness of the secondary driving display screen is reduced to a target brightness value C nit at this time. Then, it is determined whether or not the steering wheel control signal is acquired again every 5 seconds, and when the steering wheel control signal is not acquired again, the luminance value of the pilot display screen is restored to the luminance before adjustment.
In the embodiment of the application, when it is detected that the ambient light around the vehicle is lower than a preset threshold value, whether a driving control signal is acquired is judged, and if the driving control signal is acquired, the screen brightness value of the vehicle-mounted display screen is adjusted to a target brightness value; and if the driving control signal is not obtained again within the preset time, recovering the brightness value of the vehicle-mounted display screen to the brightness value before adjustment. Therefore, when the brightness of the vehicle-mounted display screen is adjusted, the brightness value of the vehicle-mounted display screen can be restored to the brightness before adjustment after the brightness is adjusted, and passengers can conveniently observe the vehicle-mounted display screen.
