[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0026] In order to solve the problem that the lighting assistance in the prior art is only for adjusting the car headlights, resulting in the inability to obtain environmental information on the left and right sides of the car when the light is poor, the present application provides a method for controlling the vehicle side view lights, such as Figure 1 As shown, the steps of the method include:

[0027] Step 101, obtaining a first steering angle signal of a vehicle steering wheel and a first vehicle speed signal of the vehicle;

[0028] In a specific example, the side view lamp is installed above the front wheel, such as Figure 2 The A and A' shown in the figure can be on the left and right sides of the vehicle, that is, in the embodiment of the present application, the side view lights can be controlled by the steering wheel angle and the vehicle speed when the vehicle turns. For example, when the vehicle turns left, the left side view lights can be controlled to light up, and of course the right side lights can also be controlled to light up at the same time. If the vehicle turns right, the right side lights can be controlled to light up, and of course the left side lights can also be controlled to light up at the same time.

[0029] Step 102, substituting the first turning angle signal and the first vehicle speed signal into a first preset formula to obtain a first angle, wherein the first angle represents an angle between the optical axis of the side view lamp in a vertical plane and a straight line perpendicular to a horizontal plane;

[0030] In a specific example, Figure 3 As shown, the plane where the X-axis and Z-axis are located is the vertical plane, the plane where the X-axis and Y-axis are located is the horizontal plane, S is the optical axis of the side view lamp, ψ0 is the angle between the optical axis and the Z axis (the straight line of the vertical plane), that is, the initial illumination angle of the side view lamp when it is turned on, and ψ1 and ψ2 are the changing angles of the optical axis when the steering wheel continues to turn.

[0031] Step 103, substituting the first turning angle signal and the first vehicle speed signal into a second preset formula to obtain a first light intensity; wherein the first light intensity represents the light intensity of the side view lamp;

[0032] It should be noted that the side view lights in the embodiment of the present application have an initial light intensity, that is, when the steering wheel is turned, the side view lights illuminate the sides of the vehicle with the initial light intensity, and then as the steering wheel continues to turn, the light intensity that the current side view lights should meet is further determined based on the steering wheel and the vehicle speed, that is, the light intensity of the side view lights is adjusted from the initial light intensity to the first light intensity to meet actual needs.

[0033] Step 104: Control the side view lights based on the first angle and the first light intensity.

[0034] It should be noted that in the process of controlling the side view lights based on the first angle and the first light intensity, the vehicle may be turning or may be stopping briefly during the turning process. If it is a short stop during the turning process, the vehicle speed signal that determines the first light intensity is the vehicle speed signal before the vehicle stops briefly, or during the short stop of the vehicle, the light intensity of the side view lights is maintained at a preset light intensity, which can be set according to the current ambient light intensity. For example, during the daytime and when the light conditions are good, the preset light intensity can be lower, such as 1000lux, 1500lux. If it is at night or during the day when the light conditions are not good, the light intensity can be set higher, such as 2500lux, 3000lux, etc. The above are just examples, and specific customized settings can be made according to actual needs.

[0035] Through the above steps 101 to 104, by obtaining the first turning angle signal of the vehicle steering wheel and the first vehicle speed signal of the vehicle, the angle between the optical axis of the vehicle side view lamp and the straight line in the plumb plane perpendicular to the horizontal plane can be determined according to the first turning angle signal and the first vehicle speed signal, and the current illumination intensity of the side view lamp can be determined. That is, in the embodiment of the present application, the illumination range and illumination intensity of the side view lamp can be determined according to the turning angle signal and the vehicle speed signal of the vehicle, so that the side of the vehicle can be illuminated by the side view lamp during the driving process of the vehicle, further improving the driving safety of the vehicle, thereby solving the problem in the prior art that the lighting assistance is only for the adjustment of the vehicle headlights, resulting in the inability to obtain environmental information on the left and right sides of the vehicle when the light is poor.

[0036] The side view lamp in the embodiment of the present application has an initial illumination intensity and an initial illumination range. Therefore, during the steering wheel rotation process, it is necessary not only to adjust the illumination intensity of the side view lamp but also to adjust the angle between the optical axis of the side view lamp and the straight line in the plumb plane and perpendicular to the horizontal plane. Based on this, the method of controlling the side view lamp based on the first angle and the first illumination intensity involved in the above step 104 in the embodiment of the present application may further include the following steps:

[0037] Step 11, obtaining an angle difference between the first angle and the second angle, and adjusting the optical axis of the side view lamp based on the angle difference so that the angle between the optical axis and the straight line is the first angle, wherein the second angle is an initial angle between the optical axis of the side view lamp and the straight line;

[0038] Step 12, adjusting the illumination intensity of the side view lamp to an illumination intensity consistent with the first illumination intensity.

[0039] For the above steps 11 and 12, combine Figure 2As shown, in the specific example, the angle between the optical axis of the side view lamp and the Z axis is the initial irradiation angle of the side view lamp, that is, ψ0. If the steering wheel is turned at this time, the angle between the current optical axis and the Z axis can be calculated according to the steering wheel angle signal and the first preset formula. If the calculated result angle between the optical axis and the Z axis is ψ1, the angle that the optical axis needs to rotate is Δψ1. If the calculated result angle between the optical axis and the Z axis is ψ2, the angle that the optical axis needs to rotate is Δψ2.

[0040] In the actual driving process of the vehicle, if you encounter a turn or a U-turn, you may need to adjust the steering wheel angle and the vehicle speed multiple times, that is, you need to control the side view lights multiple times during another turn or U-turn. Before each control, you need to wait for a preset time, such as 50ms. The waiting time is for the motor to fully release the power, because the motor may need to flip. If there is no waiting time between the next control and the previous control, the motor may burn out. Based on this, Figure 4 As shown, the method of the embodiment of the present application may also include:

[0041] 401. After each control of the side view light based on the first angle and the first light intensity, wait for a preset time period and obtain a second steering angle signal of the vehicle steering wheel and a second vehicle speed signal of the vehicle again, wherein the first steering angle signal is different from the second steering angle signal, and the first vehicle speed signal is different from the second vehicle speed signal.

[0042] It can be seen that in the embodiment of the present application, if the side view lights need to be controlled continuously for multiple times when turning, making a U-turn or in other driving conditions, there needs to be a waiting period between each control and the previous control to avoid the motor used to control the side view lights from burning out, because the motor may need to be flipped between the last control and the next control. If there is no waiting period, the motor may need to flip to release the next power before the last power release is completed. If the cycle is repeated, the motor may burn out.

[0043] In the embodiment of the present application, after the light intensity of the side view lamps is determined according to the vehicle speed signal and the steering wheel angle signal, the light intensity of the side view lamps can be further adjusted according to the ambient light intensity. For example, if it is daytime and the light is good, after the light intensity of the side view lamps is determined according to the angle signal and the vehicle speed signal, and the determined light intensity of the side view lamps is high, the current light intensity of the side view lamps can be appropriately reduced to save energy, or the side view lamp lighting mode can be automatically exited in this case. For another example, if it is night and the light is dim, after the light intensity of the side view lamps is determined according to the angle signal and the vehicle speed signal, the side of the vehicle is illuminated according to the currently determined light intensity of the side view lamps, and the effect is not good, the light intensity of the side view lamps can be further increased to improve the lighting effect on the side of the vehicle. It can be seen that in the embodiment of the present application, if Figure 5 As shown, after adjusting the illumination intensity of the side view lamp to an illumination intensity consistent with the first illumination intensity, the method of the embodiment of the present application may further include:

[0044] Step 501, obtaining the ambient light intensity;

[0045] Step 502, when the ambient light intensity exceeds a first preset threshold and the first light intensity exceeds the ambient light intensity, adjusting the light intensity of the side view lamp from the first light intensity to a second light intensity, wherein the first light intensity is higher than the second light intensity;

[0046] Step 503, when the ambient light intensity is lower than the second preset threshold and the first light intensity is lower than the third preset threshold, adjust the light intensity of the side view lamp from the first light intensity to the third preset threshold, wherein the second preset threshold is lower than the first preset threshold.

[0047] It can be seen that in the embodiment of the present application, if the current ambient light intensity is high, then during the side view light control process, the determined illumination intensity of the side view light exceeds the ambient light intensity, and the illumination intensity of the side view light can be appropriately reduced to save energy. The second illumination intensity can be set according to actual needs. If the current ambient light intensity indicates that the sight line of the current environment is very good, the second illumination intensity can be set to 0, that is, the side view light illumination mode can be automatically exited at this time. Of course, only when the ambient light intensity is higher than a certain threshold (the first preset threshold) and the illumination intensity of the side view light is calculated to be high, the illumination intensity of the side view light will be reduced or even the side view light illumination mode will be exited.

[0048] In addition, when the ambient light intensity is low, that is, the environment is dark, if the calculated light intensity of the side view lamp does not provide a good lighting effect in the current environment, the light intensity of the side view lamp can be appropriately increased to improve the illumination on the side of the vehicle when the current vehicle is turning or making a U-turn.

[0049] The first preset threshold, the second preset threshold and the third preset threshold in the above steps 501 to 503 can be set accordingly according to actual needs. For example, the first preset threshold is 1900lux, 2000lux, etc., the second preset threshold is 700lux, 800lux, etc., and the third preset threshold is 800lux, 900lux, etc.

[0050] The first preset formula and the second preset formula in the embodiment of the present application will be further explained below. That is, the method of substituting the first turning angle signal and the first vehicle speed signal into the first preset formula to obtain the first angle involved in the above step 102 may further include:

[0051] Step 21, substituting the first turning angle signal θ1 and the first vehicle speed signal V1 into the following first preset formula to obtain a first angle ψ1:

[0052] ψ1=K1θ1V1+K2θ1+ψ0

[0053] Wherein, K1 and K2 are preset calibration parameters, and ψ0 represents the initial angle between the optical axis of the side view lamp and the straight line.

[0054] It should be noted that the specific values ​​of the calibration parameters of K1 and K2 can be set accordingly according to actual needs. Figure 3 shown.

[0055] In addition, the method of substituting the first turning angle signal and the first vehicle speed signal into the second preset formula to obtain the first light intensity in the above step 103 may further include:

[0056] Step 31, the first turning angle signal θ1 and the first vehicle speed signal V1 are used in the following second preset formula to obtain the first light intensity Ix0:

[0057] Ix0=K3θ0V0+K4θ0+K5V0+I

[0058] Among them, K3, K4 and K5 are preset calibration parameters, and I represents the initial light intensity of the side view lamp.

[0059] It should be noted that the specific values ​​of the calibration parameters of K3, K4 and K5 can be set accordingly according to actual needs. The value of I can be set accordingly according to actual needs, for example, the value of I is 1800 lux.

[0060] In the embodiment of the present application, when the steering wheel is returned to the center or the vehicle speed is greater than a certain threshold, the side view lamp is not needed to illuminate the side of the vehicle. At this time, the vehicle can be controlled to exit the side view lamp auxiliary lighting mode. Based on this, the method of the embodiment of the present application, such as Figure 6 The following may also be included:

[0061] Step 601: When the acquired turning angle signal indicates that the vehicle steering wheel is returning to the center position, or the acquired vehicle speed signal indicates that the vehicle speed is greater than a fourth preset threshold, control the vehicle to exit the side view lamp auxiliary lighting mode.

[0062] In a specific example, the value of the fourth preset threshold may be 30 km / h, which may be set accordingly according to actual needs.

[0063] The present application is further explained below in conjunction with the specific implementation of the embodiment of the present application. The specific implementation provides an auxiliary lighting method for the side view lamp of an electric vehicle, which includes two methods:

[0064] Method 1) Automatic adjustment method: The ambient light brightness sensor is used to determine whether the current ambient light intensity is in a poor situation. When the ambient light brightness sensor feedbacks that the light intensity is poor, the body controller (Body Domain Controller, BDC) receives the current steering wheel angle and vehicle speed signal, and calculates the rotation angle of the side view light axis in the plumb plane based on the current steering wheel angle and vehicle speed signal, and then drives the side view light axis to adjust to the target angle. At the same time, according to the current ambient light intensity, the brightness of the light is adaptively adjusted. When the steering wheel is returned to the center or the vehicle speed is greater than 30km / h, the side view light auxiliary lighting function is automatically exited.

[0065] Method 2) Manual adjustment method: When the user enters the side view lamp auxiliary lighting function through the manual switch, the body controller receives the current steering wheel angle and vehicle speed signal, calculates the rotation angle of the side view lamp axis in the plumb plane according to the current steering wheel angle and vehicle speed signal, and then drives the side view lamp axis to adjust to the target angle. At the same time, the brightness of the light is adaptively adjusted according to the current ambient light intensity. When the user presses the side view lamp auxiliary lighting function button switch again, the side view lamp auxiliary lighting function is exited.

[0066] Combination Figure 3 In this specific implementation, the angle adjustment strategy of the side view light axis in the plumb plane is as follows:

[0067] The initial angle of the side view light axis is when the steering wheel angle is 0°, that is, it is in the return state. At this time, the angle ψ0 of the light axis in the plumb plane is generally between 10° and 15°, which is a constant and is determined by the side view light installation positions H0 and L0.

[0068] ψ0 = arctan ( L0 / H0 ) (1)

[0069] When the user starts to use the vehicle and enters a turning condition at night, the steering wheel angle gradually increases, and the BDC receives the steering wheel angle signal θ1 and the vehicle speed signal V1, and calculates the angle ψ1 of the optical axis in the plumb plane based on the steering wheel angle signal and the vehicle speed signal.

[0070] ψ1 = K1θ1V1 + K2θ1 +ψ0 (2)

[0071] Among them, K1 and K2 are calibration parameters of the optical axis rotation parameters, which are used to adapt to the revision of the influence of roll, lateral displacement of the center of mass, longitudinal displacement of the center of mass, etc. under the actual driving conditions of the vehicle. From formula (2), it can be seen that when the steering wheel angle is 0°, the angle of the optical axis in the plumb plane is ψ0. The angle of the side view light axis in the plumb plane increases with the increase of vehicle speed and angle.

[0072] After calculating ψ1, BDC simultaneously collects the current rotation angle ψ0 of the optical axis through AD. When ψ1>ψ0, it drives the optical axis to rotate forward in the direction of |ψ1-ψ0|. After BDC driving is completed, it waits for 50ms to release the motor potential energy. After the 50ms timing is completed, BDC receives the angle signal θ2 and the vehicle speed signal V2 again, and calculates the angle of the optical axis in the plumb plane as ψ2 based on the steering wheel angle signal and the vehicle speed signal.

[0073] ψ2 = K1θ2V2 + K2θ2 + ψ0 (3)

[0074] After calculating ψ2, BDC simultaneously collects the current rotation angle ψ1 of the optical axis through AD. When ψ2>ψ1, the optical axis is driven to rotate forward in the direction of |ψ2-ψ1|. After the BDC drive is completed, wait for 50ms to release the motor potential energy, and repeat this process.

[0075] When the vehicle completes the turn and starts to return to the center, BDC will adjust the steering angle according to the current steering wheel angle θ. n , vehicle speed signal V n Calculate ψ n < n-1 When the optical axis needs to be driven back, the driving angle is |ψ n -ψ n-1 |, after the drive is completed, wait for 50ms for the potential energy to be released. After the 50ms timing is completed, the BDC continues to receive the steering wheel angle signal and the vehicle speed signal, and calculates the angle ψ of the optical axis in the plumb plane based on the steering wheel angle signal and the vehicle speed signal. n+1 , and repeat this process until the steering wheel returns to the center position or the vehicle speed is ≥30km / h, then the side view lamp auxiliary lighting function is exited.

[0076] Side view light brightness adjustment strategy: When the car is driving in a dark ambient light condition, that is, when the ambient light intensity is lx≤800lux, the light intensity of the side view light needs to be brightened when the side view light auxiliary lighting function is turned on. When only the side view light auxiliary lighting function is automatically turned on, the car is not in driving state, and the steering wheel is not turned, the light intensity of the side view light is Ix0. In this condition, the light intensity of the side view light is 2000lux (initial light intensity of the side view light);

[0077] Ix0=K3θ0V0+K4θ0+ K5 V0 +2000 (4)

[0078] When the car is started and in driving state, when the steering wheel angle is θ1 and the vehicle speed is V1, the light intensity of the side view lamp is lx1.

[0079] Ix1=K3θ1V1+K4θ1+ K5 V1 +2000 (5)

[0080] Side view lamp brightness reduction strategy:

[0081] The way to brighten and weaken the side view lights can be adjusted through PWM waves. When the auxiliary lighting function of the side view lights is turned on and the ambient light brightness sensor detects that the current ambient light brightness is ≥2000lux, the BDC adjusts the duty cycle to control the output according to the current ambient light brightness to save energy. When the ambient light intensity is 800lux, the side view lights can be output according to 50% PWM waves. When the light intensity of the side view lights calculated by the BDC is less than 1000lux, the BDC adjusts the duty cycle output to brighten the light intensity of the side view lights. That is, when the ambient light intensity is high and the calculated light intensity of the side view lights is also high, the light intensity of the side view lights can be appropriately reduced to save energy. If the ambient light intensity is low and the calculated light intensity of the side view lights is also low, the light intensity of the side view lights can be appropriately increased to increase the illumination of the side of the vehicle.

[0082] Furthermore, the auxiliary lighting automatic adjustment strategy process is as follows Figure 7As shown, the ambient light brightness sensor determines whether it is daytime or nighttime according to the ambient light intensity (when the ambient light brightness sensor detects that the ambient light intensity is ≤800lux, it is considered to be nighttime, and when it is >800lux, it is considered to be daytime). If it is daytime, the side view lamp auxiliary lighting function end process (i.e., process ①) will not be executed. When it is night, it is determined whether the current vehicle is in the Ready state. If the whole vehicle is not in the Ready state, the side view lamp auxiliary lighting function end process (i.e., process ①) will not be executed. When the whole vehicle is already in the Ready state, the body controller receives the steering wheel angle signal θ1 and the vehicle speed signal V1 through the gateway controller. The BDC calculates the rotation angle ψ1 of the side view lamp axis in the plumb plane according to the current angle signal and speed signal, and drives the light axis driving motor to rotate |ψ 1- ψ0|. At the same time, according to the current ambient light intensity, the brightness of the light is adaptively adjusted to lx1, and the image information of the corresponding side of the front wheel is fed back to the large screen in real time through the panoramic image camera, helping the owner to view the blind spot field image information and avoid unnecessary scratches. BDC monitors the driving status of the optical axis drive motor. If it is still driving, wait for the drive to complete (that is, process ②). When the drive motor is driven, wait for 50ms. BDC receives the steering wheel angle signal θ2 and the vehicle speed signal V2 through the gateway controller. BDC calculates the rotation angle ψ2 of the side view light axis in the plumb plane based on the current angle signal and speed signal, and drives the optical axis drive motor to rotate |ψ 2- At the same time, according to the current ambient light intensity, the brightness of the light is adaptively adjusted by lx2. Similarly, the large screen feeds back the image information of the corresponding side of the front wheel to the large screen in real time through the 360-degree panoramic image camera to assist the owner to view the image information of the blind spot. When the steering wheel angle signal returns to positive, or the vehicle speed is greater than 30km / h, the side view lamp auxiliary lighting function is automatically exited.

[0083] Auxiliary lighting manual adjustment strategy process Figure 8 As shown, when the user manually presses the side view lamp auxiliary lighting switch button, the BDC receives the steering wheel angle signal θ1 and the vehicle speed signal V1 through the gateway controller. The BDC calculates the rotation angle ψ1 of the side view lamp axis in the plumb plane according to the current steering angle signal and vehicle speed signal, and drives the optical axis driving motor to rotate |ψ 1-ψ0|. At the same time, according to the current ambient light intensity, the brightness of the light is adaptively adjusted to lx1, and the image information of the corresponding side of the front wheel is fed back to the large screen in real time through the panoramic image camera, helping the owner to view the blind spot field image information and avoid unnecessary scratches. BDC monitors the driving status of the optical axis drive motor. If it is still driving, wait for the drive to complete (that is, process ②). When the drive motor is driven, wait for 50ms to complete. BDC receives the steering wheel angle signal θ2 and the vehicle speed signal V2 through the gateway controller. BDC calculates the rotation angle ψ2 of the side view light axis in the plumb plane based on the current angle signal and speed signal, and drives the optical axis drive motor to rotate |ψ 2- At the same time, according to the current ambient light intensity, the brightness of the light is adaptively adjusted to lx2.
