[0013] Secondly, embodiments of this application also provide a vehicle driver assistance device, comprising:

[0014] The response module is used to activate the anti-reflective mode in response to control commands;

[0015] The first acquisition module is used to acquire a first light intensity value detected by a first illuminance sensor installed at a first target mounting position on the target exterior mirror of the vehicle. The first light intensity value is the intensity value of external light illuminating the target exterior mirror from an external light source.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] In existing technology, when driving at night or in low light or poor lighting conditions, if a vehicle behind is using its high beams, the light from the high beams may be reflected into the driver's cabin through the side mirrors of the vehicle in front, which may affect the driver's vision and even cause danger.

[0036] To address the aforementioned issues, this application provides a method, device, electronic device, and storage medium for assisting driving of a vehicle, which will be described below through embodiments.

[0037] To facilitate understanding of this application, the technical solutions provided in this application will be described in detail below with reference to specific embodiments.

[0038] Please see Figure 1 This application provides an embodiment of a vehicle assisted driving method, executed by a vehicle microcontroller, the method comprising:

[0039] S101, respond to control commands to activate anti-reflective mode.

[0040] Specifically, the headlight dimming module (ADIM) on the vehicle body can determine daytime or nighttime conditions or the external environment by analyzing the duty cycle of the PWM (Pulse Width Modulation) output by the ADIM. If the vehicle's electronic control unit (ECU) determines that the conditions for turning on the headlights are met, the command to activate the anti-glare mode is sent synchronously with the CAN message from the ECU that turns on the headlights. Alternatively, a photosensor and a separate ECU can be used, integrated into the vehicle's CAN network. The CAN network then sends the ambient light information to the MCU (Microcontroller Unit) or SOC (System on Chip) to determine the ambient light conditions. If the conditions for activating the anti-glare mode are met, a control command is generated.

[0041] S102. Obtain the first light intensity value detected by the first illuminance sensor installed at the first target mounting position of the target exterior mirror of the vehicle. The first light intensity value is the intensity value of the external light illuminating the target exterior mirror from an external light source.

[0042] like Figure 6 As shown, the first illuminance sensor 610 is installed at the first target mounting position on the target exterior mirror 600 of the vehicle. The target exterior mirror 600 is either the left or right exterior mirror of the vehicle. The first target mounting position can be within the plane of the reflector side of the exterior mirror. The first light intensity value obtained by the first illuminance sensor 610 is the intensity value of the external light illuminating the target exterior mirror 600 from an external light source, which can be the intensity value of the strong light illuminating the rear headlights.

[0043] S103. Based on the comparison result between the first light intensity value and the first light intensity threshold, adjust the target external sight mirror to the target adjustment position to change the reflection angle of the target external sight mirror to the external light.

[0044] The first light intensity threshold here is a preset light intensity threshold, a fixed value calibrated by researchers after multiple experiments. When the first light intensity value is greater than the first light intensity threshold, it is considered that the current target rearview mirror is being illuminated by strong light and reflected into the driver's cabin. At this time, the position of the target exterior mirror 600 needs to be adjusted. The target adjustment position here is a preset exterior mirror position. When the exterior mirror is adjusted to the target exterior mirror 600, the reflection angle of the exterior mirror to external light changes, and the light reflected by the exterior mirror no longer enters the driver's cabin.

[0045] S104. Control the vehicle's rear camera to turn on, acquire video data behind the vehicle while it is driving, and send it to the vehicle's in-vehicle display for display.

[0046] The rear-view camera here can be installed at the rear of the vehicle, such as on the rear bumper, to obtain information about what's behind the vehicle. After confirming that the anti-glare mode is activated, while adjusting the target side mirror 600 to the target position, the rear-view camera should also be activated to display video data of the area behind the vehicle on the in-vehicle display, allowing the driver to be aware of the road conditions behind the vehicle even when the side mirror is being adjusted.

[0047] S105. Obtain the second light intensity value detected by the second illuminance sensor installed at the second target installation position of the target external mirror. The second light intensity value is the intensity value of the external light emitted by the external light source onto the target external mirror when the target external mirror is in the target adjustment position, as collected by the second illuminance sensor.

[0048] like Figure 7As shown, the second target installation position is on the surface of the target exterior mirror 600 opposite to the side connected to the vehicle. When the target rearview mirror is adjusted to the target adjustment position, the intensity value of the external light illuminating the target exterior mirror 600 can be detected by the second illuminance sensor 620. The purpose of obtaining the second light intensity value detected by the second illuminance sensor 620 is to determine whether the intensity of the current external light has decreased, that is, to determine whether the headlights of the following vehicle are turned off.

[0049] S106. Determine whether to exit anti-reflective mode based on the second light intensity value.

[0050] Specifically, it is determined whether the second light intensity value is less than the second light intensity threshold. If the second light intensity value is less than the second light intensity threshold and remains so for a preset duration, then the anti-reflective mode is exited. Here, the second light intensity threshold is less than the first light intensity threshold. The second light intensity threshold is a preset light intensity threshold. When the second light intensity value is less than the second light intensity threshold, it can be assumed that the high beams of the following vehicle are off, and no strong light will be reflected into the driver's cabin, thus exiting the anti-reflective mode.

[0051] The vehicle assisted driving method provided in this application, by activating the anti-reflective mode, obtains the first light intensity value detected by the first illuminance sensor 610 installed at the first target mounting position of the target exterior mirror 600 of the vehicle, and adjusts the target exterior mirror 600 to the target adjustment position based on the comparison result of the first light intensity value and the first light intensity threshold. At the same time, the video of the situation behind the vehicle is displayed on the vehicle display. While preventing the strong light from being reflected into the driver's cab by the left and right exterior mirrors, the driver can also observe the situation behind the vehicle.

[0052] Please see Figure 2 This application provides a method for adjusting a target external sight mirror according to an embodiment of the present application. The method includes:

[0053] S201. Determine whether the first light intensity value is greater than the first light intensity threshold;

[0054] S202. If the first light intensity value is greater than the first light intensity threshold, then control the target external mirror to rotate in the first preset direction by a first preset angle value, and control the target external mirror to rotate in the second preset direction by a second preset angle value, so as to adjust the target external mirror to the target adjustment position.

[0055] The first preset direction can be either clockwise or counterclockwise around the first mounting axis of the target exterior mirror, and the second preset direction can be either clockwise or counterclockwise around the second mounting axis of the target exterior mirror. The first and second mounting axes are perpendicular, meaning one involves flipping the target exterior mirror 600 up and down, and the other involves rotating it left and right. The first and second preset angle values ​​are fixed angle values ​​determined by researchers through numerous experiments. For example, the target exterior mirror 600 can be flipped down 30° and rotated 45° away from the vehicle to reach the target adjustment position. When the target exterior mirror 600 is adjusted to the target adjustment position, it can reflect the strong light originally reflected into the driver's cab to other directions, thereby preventing the driver in the cab from being affected by the strong light and thus affecting vehicle driving.

[0056] Please see Figure 3 Another method for adjusting a target external sight mirror, provided in an embodiment of this application, includes:

[0057] S301. Determine whether the currently detected first light intensity value is greater than the first light intensity threshold;

[0058] S302. If the detected first light intensity value is greater than the first light intensity threshold, then control the target external mirror to rotate in the first preset direction by a third preset angle value, and / or control the target external mirror to rotate in the second preset direction by a fourth preset angle value.

[0059] The third and fourth preset angle values ​​here are preset fixed angle values, and the first preset angle value is greater than the third preset angle value, and the second preset angle value is greater than the fourth preset angle value. These third and fourth preset angle values ​​are preset angle values, fixed angle values ​​calibrated by the R&D personnel after multiple experiments. For example, when the detected first light intensity value is greater than the first light intensity threshold, the target exterior mirror 600 can be controlled to tilt downwards by 10° or rotate 10° away from the vehicle. It can also tilt downwards by 10° and rotate 10° away from the vehicle at the same time.

[0060] S303. Determine whether the position of the target external sight mirror after rotation has been adjusted to the target adjustment position;

[0061] S304. If the position of the target external sight mirror after rotation is not adjusted to the target adjustment position, return to step S301.

[0062] Specifically, if the position of the target exterior mirror 600 after adjustment in step S302 is the same as its position in either the first preset direction or the second preset direction in the target adjustment position, or if its position is the same in both directions, then it is determined that the position of the rotated target exterior mirror 600 has been adjusted to the target adjustment position. If it is determined that the position of the rotated target exterior mirror 600 has not been adjusted to the target adjustment position, then the target exterior mirror 600 is controlled to tilt downwards by 10° or rotated 10° away from the vehicle. It can also tilt downwards by 10° and rotate 10° away from the vehicle at the same time, but the adjustment method is the same each time. Until it is determined that the position of the rotated target exterior mirror 600 has been adjusted to the target adjustment position, the target exterior mirror 600 is no longer adjusted.

[0063] Furthermore, control commands are obtained in the following ways:

[0064] In the first scenario, the third light intensity value detected by the vehicle's third light sensor is obtained. The third light intensity value represents the intensity of the ambient light in the driving environment where the vehicle is located. When the third light intensity value is less than the preset ambient light intensity value, a control command is generated. The control command is used to control the vehicle to turn on the headlights and activate the anti-reflective mode.

[0065] In this scenario, the third light sensor can be a vehicle-mounted environmental sensor used to detect the intensity of ambient light in the vehicle's driving environment. It is typically mounted on the vehicle's rearview mirror. When the intensity of the third light sensor is less than a preset ambient light level, it indicates that the vehicle is likely driving in a dimly lit environment, such as at night or in a tunnel, where there is little or no lighting. In such conditions, the vehicle will usually temporarily turn on its high beams. Therefore, a control command is generated to activate the high beams in the vehicle's headlights and simultaneously activate the anti-glare mode to prevent light from the high beams of following vehicles from reflecting into the driver's cab of the vehicle in front.

[0066] In the second scenario, in response to the user's command to activate the anti-reflective mode, a control command is generated, which is used to control the vehicle to activate the anti-reflective mode.

[0067] In this situation, the driver can manually activate the anti-reflective mode via the in-vehicle display or buttons, generating a control command to activate the mode. Drivers can manually activate the anti-reflective mode according to their needs or driving habits, ensuring driving safety.

[0068] Please see Figure 4 This application provides a method for restoring a target external sight mirror according to an embodiment of the present application. The method includes:

[0069] S401. Record the current position information of the target's external sight when the anti-reflective mode is turned on.

[0070] S402. Determine whether the current position information of the target external sight is consistent with the stored historical position information;

[0071] S403. If they are inconsistent, replace the historical position information with the current position information of the target's external sight and store it.

[0072] S404. When exiting the anti-reflective mode, restore the position of the target external mirror based on the stored historical location information.

[0073] Specifically, upon activating the anti-reflective mode, the current position information of the target external sight mirror 600 is recorded. It is then determined whether the current position information of the target external sight mirror 600 matches the stored historical position information. If they do not match, the current position information of the target external sight mirror needs to be replaced with the historical position information. When exiting the anti-reflective mode, the historical position information of the target external sight mirror 600 stored in the memory is retrieved, and the position of the target external sight mirror 600 is restored to a position consistent with the historical position information.

[0074] This application stores the historical position of the target exterior mirror. When the anti-reflective mode is exited, the target exterior mirror is restored to the position before the anti-reflective mode was activated. This avoids the problem of the exterior mirror's position changing due to adjustment, which would affect its use and ensure the driver's safety.

[0075] Furthermore, once the target external sight is adjusted to the target adjustment position, if the first light intensity value is greater than the first light intensity threshold, the target external sight is adjusted to a safe position.

[0076] The safe position here can be the adjustable limit position in the first preset direction and / or the second preset direction of the exterior mirror adjustment. Because the environment changes rapidly and is complex during vehicle operation, if the first light intensity value is still greater than the first light intensity threshold after adjusting the target exterior mirror 600 to the target adjustment position (meaning strong light will still reflect into the cab), then the target exterior mirror 600 is directly adjusted to the safe position to ensure that no strong light reflects into the cab, further improving the reliability of this method. Specific implementation examples:

[0078] This application proposes a method for adaptive adjustment of vehicle exterior mirrors, the method specifically including:

[0079] (1) Detect whether the current external environment is nighttime by measuring the illuminance and confirm whether the driver has turned on the anti-reflective mode.

[0080] (2) Before activating the anti-reflective mode, the driver should keep the current target external mirror angle 600 set and store it so that the vehicle can automatically return to the original target external mirror angle 600 after exiting the anti-reflective mode.

[0081] (3) When the vehicle behind turns on its high beams, the strong light shines on the target side mirror 600, triggering the anti-reflective mode and adjusting the target side mirror 600 to the target adjustment position. At the same time, the central control display screen and the rear reversing camera work together to turn on the reversing camera or a special camera with backlight shooting function, and project the situation behind the vehicle onto the central control display screen.

[0082] (4) When the strong light on the rearview mirror disappears, exit the anti-reflective mode and reset the target external mirror 600.

[0083] By using the above methods, we can avoid the problem of vehicle headlight interference and allow drivers to observe the situation behind the vehicle through the rearview mirror in situations such as nighttime, thus ensuring driving safety and avoiding traffic accidents.

[0084] Based on the same inventive concept, this application also provides a vehicle assistance driving device corresponding to the vehicle assistance driving method. Since the principle of the vehicle assistance driving device in this application is similar to the vehicle assistance driving method described above in this application, the implementation of the vehicle assistance driving device can refer to the implementation of the method, and the repeated parts will not be described again.
