[0068] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are presented in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and based on various changes and modifications of the following embodiments. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present application, and the embodiments can be combined and referenced with each other on the premise of no contradiction.

[0069] In the prior art, whether it is a mechanical rearview mirror or an electronic rearview mirror, when the vehicle enters the main road from the ramp or the turning is slightly large, the rearview mirror can only see a very small area of the vehicle body view, and the driver needs to actively move the viewing angle or combine the window to judge the driving conditions outside the vehicle, which causes the vehicle side view blind area, resulting in vehicle scratching or collision accidents. In order to solve this problem, the present application provides a rearview mirror adjustment method to reduce the blind area.

[0070] Referring to Figure 1 , a flow chart of steps in a rearview mirror adjustment method provided in the present application is shown, which can include:

[0071] Step 101, acquiring the steering angle value of the front wheel of the vehicle when the vehicle is turning, the default angle value and the default telescopic distance value of the target rearview mirror, the preset eyeball center position and the actual eyeball center position of the current driver.

[0072] The steering angle value of the front wheel of the vehicle in the present application can be obtained by a steering angle sensor installed on the steering column or steering rack, or can be estimated by capturing the road image in front through a camera and image processing technology, or can be estimated by measuring the acceleration and angular velocity of the vehicle through an inertial measurement unit combined with the data of other sensors, or can be inferred by obtaining the working state and feedback signal of the motor of the electric power steering (EPS) system. The present application does not make specific limitations here.

[0073] The target rearview mirror of the present application supports forward and backward rotation adjustment, and also supports outward extension and inward contraction. In the default state, the target rearview mirror has a specific angle B° with the vehicle body, and a default distance C cm between the target rearview mirror and the vehicle body. The target rearview mirror supports adjustment of 0-45° forward or backward based on the specific angle, and also supports adjustment of 0-10 cm outward or inward based on the default distance. It should be noted that the specific values can be adjusted according to the design situation, and the present application does not make specific limitations here.

[0074] The present application also takes into account the differences in height and sitting posture of different persons, so the center of the eye of the person is tracked. The preset eye center position and the actual eye center position of the current driver are obtained through the vehicle-mounted camera. The preset eye center position refers to the position of the eye center when the driver is in the standard position set by the system initialization on the seat, at which time the eye center has a fixed vertical distance from the vehicle-mounted camera. When drivers of different heights and sitting postures sit in the driving position, the seat will be adjusted, and after each adjustment, the actual eye center position of the current driver can be obtained, and the updated vertical distance between the eye center of the current driver and the vehicle-mounted camera can also be obtained.

[0075] Step 102, in the case where the steering angle value of the front wheel of the vehicle reaches the target preset value, the current steering angle value of the rear wheel of the vehicle and the steering increase angle value of the rear wheel of the vehicle based on the current steering angle value are obtained.

[0076] The adjustment of the target rearview mirror in the present application is conditional. If the steering angle of the front wheel of the vehicle is very small and does not reach the target preset value, the target rearview mirror will not trigger adjustment at this time. If the steering angle of the front wheel of the vehicle continues to increase and reaches the target preset value, the current steering angle value of the rear wheel of the vehicle when the steering angle of the front wheel of the vehicle is just equal to the target preset value is recorded. On this basis, if the vehicle continues to steer, the steering increase angle value of the rear wheel of the vehicle based on the current steering angle value is continuously recorded.

[0077] For example, the target preset value is set as 30°. If the steering angle of the front wheel of the vehicle is detected as 20°, the target mirror will not be triggered to adjust because 20°<30°. If the steering angle of the front wheel of the vehicle is detected as 30°, the target preset value is reached, and the steering angle of the front wheel of the vehicle is obtained as 30° and the current steering angle value of the rear wheel of the vehicle is obtained as 10°. If the vehicle continues to steer, the steering angle value of the rear wheel of the vehicle is detected as 20°, and the steering angle value of the rear wheel of the vehicle based on the current steering angle value continues to steer by 10° because 20°-10°=10°.

[0078] It should be noted that if the vehicle continues to steer after the steering angle value of the front wheel of the vehicle reaches the target preset value, the steering angle value of the front wheel of the vehicle will also change in real time, so the steering angle value of the front wheel of the vehicle obtained will be updated in real time with the continuous steering of the vehicle, and is not a fixed value.

[0079] In step 103, the first angle value of the front and rear adjustment of the target mirror and the first length value of the telescopic adjustment are obtained by the steering angle value of the front wheel of the vehicle, the steering increase angle value, the default angle value, and the default telescopic distance value.

[0080] The angle value and the length value of the target mirror will be adjusted according to the steering increase angle value of the rear wheel of the vehicle, and there is a conversion mapping relationship between the angle value of the target mirror and the steering increase angle value of the rear wheel of the vehicle, and there is also a conversion mapping relationship between the length value of the target mirror and the steering increase angle value of the rear wheel of the vehicle. For example, the mapping ratio of the angle value is set as k1, the mapping ratio of the length value is set as k2, the steering increase angle value of the rear wheel of the vehicle is x1, the angle value of the target mirror is x2, and the length value of the target mirror is y2. Then x2=k1*x1, y2=k2*x1.

[0081] Further, in step 103, as shown in Figure 2

[0082] In step 1031, a first mapping ratio set in advance for the steering increase angle value and the first angle value and a second mapping ratio set for the steering increase angle value and the first length value are obtained.

[0083] In step 1032, the first angle value of the front and rear adjustment of the target mirror is obtained according to the preset angle value conversion strategy, the steering angle value of the front wheel of the vehicle, the steering increase angle value, the default angle value, and the first mapping ratio.

[0084] ​It should be noted that the preset angle value conversion strategy provided by the target rearview mirror in the present application is: the default angle value + the first angle value = the steering angle value of the front wheel of the vehicle + the first mapping ratio * the steering increase angle value, so the first angle value = the steering angle value of the front wheel of the vehicle + the first mapping ratio * the steering increase angle value - the default angle value. In addition, the target rearview mirror in the present application includes a driver's seat rearview mirror installed outside the driver's seat and a copilot's seat rearview mirror installed outside the copilot's seat. The adjustment directions of the rearview mirrors in different positions are different. The specific adjustment direction can be determined according to the positive and negative of the first angle value. If the calculated first angle value is positive, the driver's seat rearview mirror is controlled to adjust forward and the copilot's seat rearview mirror is controlled to adjust backward, and the size of the adjustment is determined according to the first angle value. The specific steps include:

[0085] After obtaining the product of the steering increase angle value and the first mapping ratio, the product is summed with the steering angle value of the front wheel of the vehicle to obtain a first target value;

[0086] The first target value is subtracted by the default angle value to obtain the first angle value;

[0087] If the first angle value is greater than 0, the driver's seat rearview mirror is controlled to adjust forward by the first angle, and the copilot's seat rearview mirror is controlled to adjust backward by the first angle;

[0088] If the first angle value is less than 0, the driver's seat rearview mirror is controlled to adjust backward by the first angle, and the copilot's seat rearview mirror is controlled to adjust forward by the first angle.

[0089] As shown in Figure 3 When the vehicle needs to turn left during horizontal driving, the rearview mirror on the driver's side of the driver's seat will be adjusted forward based on the fixed viewing angle, that is, after the steering angle value of the front wheel of the vehicle reaches the target preset value, the rearview mirror on the driver's side of the driver's seat will be adjusted forward to increase the steering viewing angle.

[0090] The above process dynamically adjusts the rearview mirrors of the driver's seat and the copilot's seat through the steering angle of the front wheel of the vehicle to ensure that the driver can obtain the best field of view at different steering angles, thereby improving the safety of vehicle driving in complex road conditions.

[0091] In step 1033, according to the preset telescopic distance value conversion strategy, the steering angle value of the front wheel of the vehicle, the steering increase angle value, the default telescopic distance value, the second mapping ratio, a first length value of the target rearview mirror telescopic adjustment is obtained.

[0092] The preset telescopic distance conversion strategy for the target rearview mirror is: the default telescopic distance value + the first length value = the steering angle value of the front wheels of the vehicle + the second mapping ratio * the steering increase angle value, so the first length value = the steering angle value of the front wheels of the vehicle + the second mapping ratio * the steering increase angle value - the default telescopic distance value. In addition, the target rearview mirror includes a driver's seat rearview mirror and a front passenger's seat rearview mirror, and the telescopic adjustment of rearview mirrors at different positions is different. The specific telescopic adjustment can be determined according to the positive and negative of the first length value. If the calculated first length value is positive, the driver's seat rearview mirror is controlled to extend outward and the front passenger's seat rearview mirror is controlled to retract inward. If the calculated first length value is negative, the driver's seat rearview mirror is controlled to retract inward and the front passenger's seat rearview mirror is controlled to retract inward and extend outward. The size of the adjustment is determined according to the first angle value. The specific steps include:

[0093] After obtaining the product of the steering increase angle value and the second mapping ratio, the product is summed with the steering angle value of the front wheels of the vehicle to obtain a second target value;

[0094] The second target value is subtracted by the default telescopic distance value to obtain the first length value;

[0095] If the first length value is greater than 0, the driver's seat rearview mirror is controlled to extend outward by the first length, and the front passenger's seat rearview mirror is controlled to retract inward by the first length;

[0096] If the first length value is less than 0, the driver's seat rearview mirror is controlled to retract inward by the first length, and the front passenger's seat rearview mirror is controlled to extend outward by the first length.

[0097] The above process dynamically adjusts the telescopic distance of the driver's seat and the front passenger's seat rearview mirrors through the steering angle of the front wheels of the vehicle to ensure that the driver can obtain the best field of view at different steering angles.

[0098] Step 104, by presetting the eye center position and the actual eye center position, obtaining the eye front-back offset distance value of the current driver.

[0099] In the present application, the height and sitting posture differences of different drivers will be considered to be different in the adjustment requirements of the target rearview mirror, so the personnel eye center position tracking technology is added. The movement of the personnel eye center is determined to determine the subsequent adjustment of the target rearview mirror. Therefore, the movement of the personnel eye center needs to be determined first.

[0100] Based on this, the application will first obtain the first distance (assuming D1) between the target camera and the preset eyeball center position. The preset eyeball center position generally refers to the position of the eyeball center when the vehicle is in a horizontal lane and the driver is on the seat in the standard position set by the system initialization. At this time, the seat is in the factory design state and has not been adjusted. Then, when the driver adjusts the seat according to his own habits and body factors, the second distance (assuming D2) between the target camera and the actual eyeball center position is obtained, and the target difference value (assuming ΔD) of the first distance minus the second distance is calculated, ΔD=D1-D2. According to the positive and negative of the target difference value, the eyeball deviation direction of the current driver is judged. If ΔD>0, it indicates that the eyeball of the current driver deviates forward by ΔD distance, and if ΔD<0, it indicates that the eyeball of the current driver deviates backward by ΔD distance. The distance here is the vertical distance between the eyeball center and the target camera

[0101] Further, step 104, as shown in Figure 4

[0102] Step 1041, obtaining the first distance between the target camera and the preset eyeball center position.

[0103] Step 1042, obtaining the second distance between the target camera and the actual eyeball center position.

[0104] Step 1043, obtaining the target difference value of the first distance minus the second distance.

[0105] Step 1044, if the target difference value is greater than 0, the eyeball of the current driver deviates forward by the target difference value.

[0106] Step 1045, if the target difference value is less than 0, the eyeball of the current driver deviates backward by the target difference value.

[0107] In the above process, the difference between the eyeball center position captured by the camera and the preset standard position is used to judge the deviation direction and distance of the driver's eyeball, which is convenient for subsequent determination of the adjustment of the target rearview mirror according to the movement of the eyeball center position.

[0108] Step 105, adjusting the first angle value and the first length value by the eyeball forward and backward deviation distance value to obtain the second angle value of the target rearview mirror forward and backward adjustment and the second length value of the telescopic adjustment.

[0109] ​After the application obtains the eyeball front-back offset distance value (which can be considered as the target difference value), the application calculates the angle adjustment value and the length adjustment value of the target rearview mirror based on the value, because the target rearview mirror is adjusted according to the steering condition of the vehicle, so the second angle value and the second length value are obtained by continuing to superimpose the angle adjustment value and the length adjustment value based on the first angle value and the first length value adjusted according to the steering condition of the vehicle. The angle adjustment value is not directly obtained from the eyeball front-back offset distance value. The application sets a first adjustment coefficient (assuming k3) for the eyeball front-back offset distance value and the angle adjustment value, and a second adjustment coefficient (assuming k4) for the eyeball front-back offset distance value and the length adjustment value, and then defines the angle adjustment value = the first adjustment coefficient * the eyeball front-back offset distance value, and the length adjustment value = the second adjustment coefficient * the eyeball front-back offset distance value. The first adjustment coefficient is used to determine the conversion relationship between the eyeball front-back offset distance value and the angle value of the target rearview mirror, and the second adjustment coefficient is used to determine the conversion relationship between the eyeball front-back offset distance value and the length value of the target rearview mirror. The sum of the angle adjustment value and the first angle value is the second angle value of the target rearview mirror adjusted front and back, and the sum of the length adjustment value and the first length value is the second length value of the target rearview mirror adjusted front and back. The specific steps include:

[0110] Obtain the first adjustment coefficient and the second adjustment coefficient set in advance for the eyeball front-back offset distance value;

[0111] After obtaining the product of the first adjustment coefficient and the target difference value, sum the product and the first angle value to obtain the second angle value of the target rearview mirror adjusted front and back;

[0112] After obtaining the product of the second adjustment coefficient and the target difference value, sum the product and the first length value to obtain the second length value of the target rearview mirror adjusted front and back.

[0113] By further adjusting the target rearview mirror in combination with the driver's eye position information, the accuracy of the rearview mirror adjustment can be improved, the driver's rearward viewing angle can be ensured to be in the best position, and the driving safety can be improved.

[0114] Step 106, adjust the target rearview mirror through the second angle value and the second length value.

[0115] After determining the second angle value of the target rearview mirror that needs to be adjusted front and back, the application also determines whether the target rearview mirror is adjusted forward or backward through the positive and negative of the second angle value, and after determining the second length value of the target rearview mirror that needs to be adjusted front and back, the application also determines whether the target rearview mirror is adjusted outward or inward through the positive and negative of the second length value, and then the specific adjustment can be performed according to the above content.

[0116] Specifically, since the target rearview mirror comprises an electric slide rail and a limited rotation motor, the electric slide rail controls the target rearview mirror to extend at a high level and to retract at a low level, and the limited rotation motor controls the target rearview mirror to deflect forward at a high level and to deflect backward at a low level. Therefore, the contraction and extension of the target rearview mirror are controlled by controlling the level state of the electric slide rail, and the forward or backward deflection of the target rearview mirror is controlled by controlling the level state of the limited rotation motor. Since the adjustment of the target rearview mirror has specific numerical values, the second angle value and the second length value of the specific adjustment can be achieved by adjusting the movement time length of the motor.

[0117] Further, step 106, as shown in Figure 5

[0118] Step 1061, obtain a third mapping ratio set in advance for the angle value of the target rearview mirror and the movement time length of the limited rotation motor, and a fourth mapping ratio set for the length value of the target rearview mirror and the movement time length of the electric slide rail.

[0119] Step 1062, obtain the first movement time length of the limited rotation motor through the third mapping ratio and the second angle value.

[0120] Step 1063, obtain the second movement time length of the electric slide rail through the fourth mapping ratio and the second length value.

[0121] Step 1064, obtain the first level state of the limited rotation motor through the second angle value, and obtain the second level state of the electric slide rail through the second length value.

[0122] Step 1065, control the limited rotation motor to adjust the target rearview mirror forward and backward through the first level state and the first movement time length, and control the electric slide rail to adjust the target rearview mirror to extend and retract through the second level state and the second movement time length.
