Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a method, device, vehicle, and storage medium for adjusting vehicle headlights. Background Technology

[0002] When driving at night, vehicles typically turn on their lights. If the lights cannot be adjusted to the correct direction when turning at night, the road ahead is dark, making it difficult for the driver to see clearly and posing a significant safety hazard.

[0003] Currently, there are functions that adjust the direction of headlights based on the steering wheel angle. However, the steering wheel angle is input by the driver based on their experience driving on dark curves. On one hand, the headlight direction won't adjust before the driver adjusts the steering wheel, and the driver still cannot clearly see the dark road ahead. The headlights only adjust after the steering wheel is adjusted, resulting in a lag in headlight adjustment. On the other hand, while adjusting the steering wheel may illuminate a portion of the dark road ahead, the illuminated area cannot accurately guarantee the safety of driving along the curve. Therefore, nighttime driving safety is difficult to guarantee. Summary of the Invention

[0022] Currently, vehicles typically turn on their lights when driving at night. However, if the direction of the lights cannot be adjusted when turning at night, the road ahead is dark, making it difficult for the driver to see the road ahead accurately, which poses a significant safety hazard for nighttime driving.

[0023] Currently, there are functions that adjust the headlight direction based on the steering wheel angle. However, the steering wheel angle is input by the driver based on their experience driving on dark curves. On one hand, the headlight direction won't adjust before the driver adjusts the steering wheel, and the driver still cannot clearly see the dark road ahead. The headlights only adjust after the steering wheel is adjusted, resulting in a lag in headlight adjustment. On the other hand, while adjusting the steering wheel may illuminate a portion of the dark road ahead, the illuminated area cannot accurately guarantee the illumination along the vehicle's direction of travel on a curve.

[0024] Based on this, combined Figures 1 to 11 As shown, this embodiment provides a method for adjusting vehicle headlights. This method is executed by a vehicle headlight adjustment device 100 to solve the problem that the safety of vehicles driving at night is difficult to guarantee in the prior art.

[0025] S100: The vehicle headlight adjustment method includes: after the vehicle headlights are turned on, the vehicle headlight adjustment device 100 obtains the current location information of the vehicle and the navigation trajectory information of the vehicle.

[0026] For example, the vehicle headlight adjustment device 100 can obtain the vehicle's current location information through the vehicle's positioning system, such as a GPS positioning system or a Beidou positioning system. Simultaneously, the vehicle headlight adjustment device 100 can also obtain in-vehicle navigation information to acquire the vehicle's navigation trajectory information.

[0027] S200: The vehicle headlight adjustment method further includes: the vehicle headlight adjustment device 100 determines the current vehicle orientation angle value Θ based on the vehicle's current position information and determines the vehicle's navigation orientation angle value Ω based on the vehicle's navigation trajectory information.

[0028] In one exemplary embodiment of this application, the vehicle headlight adjustment device 100 can directly output the current vehicle orientation angle value Θ based on the vehicle's built-in inertial navigation sensor. The vehicle orientation angle value Θ can refer to the angle between the vehicle's center of gravity velocity direction and the horizontal axis in a ground coordinate system.

[0029] In an exemplary embodiment of this application, the step of the vehicle headlight adjustment device 100 determining the vehicle's navigation orientation angle value Ω based on navigation trajectory information includes: S210: The vehicle headlight adjustment device 100 determines the real-time coordinates (X0, Y0) of the vehicle based on the vehicle's current position information.

[0030] S220: The vehicle headlight adjustment device 100 determines multiple predetermined coordinate points based on navigation trajectory information; and selects two predetermined coordinate points from the multiple predetermined coordinate points based on real-time coordinate points, then determines the two predetermined coordinate points as a first predetermined coordinate point (X, Y) and a second predetermined coordinate point (X1, Y1), respectively. Specifically, the step of the vehicle headlight adjustment device 100 selecting two predetermined coordinate points from the multiple predetermined coordinate points based on real-time coordinate points and determining the two predetermined coordinate points as a first predetermined coordinate point and a second predetermined coordinate point, respectively, includes: S221: The user inputs the vehicle's destination on the in-vehicle navigation system, and then the in-vehicle navigation system automatically generates a predetermined route for the vehicle so that the vehicle headlight adjustment device 100 can obtain the predetermined route of the vehicle.

[0031] S222: The vehicle headlight adjustment device 100 determines multiple predetermined coordinate points that the vehicle needs to pass along the predetermined path based on the predetermined path. Among these multiple predetermined coordinate points, the interval between any two adjacent predetermined coordinate points may be the same.

[0032] S223: Obtain the longitude of each predetermined coordinate point through the vehicle headlight adjustment device 100. ,latitude and the height of the earth Among them, the ground height Also known as geodetic height or ellipsoidal height, it refers to the distance from a point on the ground along the normal to the ellipsoid to the ellipsoid surface. It is negative inside the reference ellipsoid surface and positive outside the reference ellipsoid surface.

[0033] S224: The longitude of each predetermined coordinate point is adjusted via the vehicle headlight adjustment device 100. ,latitude and the height of the earth This is converted into the x-coordinate and y-coordinate values ​​of each predetermined coordinate point. Specifically, the x-coordinate value is calculated as follows: The ordinate value y is calculated as follows: .

[0034] It should be understood that N is calculated as follows: The calculation method for f is as follows: Where a is the radius of the Earth's major axis and b is the radius of the Earth's minor axis.

[0035] S225: Based on the difference between the x-coordinate value X0 and the y-coordinate value Y0 of the real-time coordinate point and the x-coordinate value x and the y-coordinate value y of each predetermined coordinate point, two predetermined coordinate points are selected, namely the first predetermined coordinate point (X, Y) and the second predetermined coordinate point (X1, Y1).

[0036] It should be understood that the first predetermined coordinate point (X, Y) is the coordinate point among multiple predetermined coordinate points whose x-coordinate value and y-coordinate value are closest to the real-time coordinate point (X0, Y0), that is, the coordinate point with the smallest difference between x and X0 plus the smallest difference between y and Y0. The second predetermined coordinate point (X1, Y1) is the coordinate point among multiple predetermined coordinate points that the vehicle is scheduled to pass through at the next moment after passing the first predetermined coordinate point (X, Y).

[0037] S230: The vehicle headlight adjustment device 100 determines the navigation orientation angle value Ω based on the difference between the second predetermined coordinate point (X1, Y1) and the real-time coordinate point (X0, Y0). Specifically, the step of the vehicle headlight adjustment device 100 determining the navigation orientation angle value Ω based on the difference between the second predetermined coordinate point (X1, Y1) and the real-time coordinate point (X0, Y0) includes: S231: The abscissa value X1 of the second predetermined coordinate point is subtracted from the abscissa value X0 of the real-time coordinate point by the vehicle headlight adjustment device 100 to obtain the abscissa difference; the ordinate value Y1 of the second predetermined coordinate point is subtracted from the ordinate value Y0 of the real-time coordinate point by the vehicle headlight adjustment device 100 to obtain the ordinate difference; the arctangent value of the ordinate difference divided by the abscissa difference is calculated to obtain the navigation orientation angle value Ω. Specifically: .

[0038] S300: The vehicle headlight adjustment device 100 adaptively adjusts the target illumination angle value of the vehicle headlights based on the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ; wherein, the target illumination angle value is the illumination angle value of the vehicle headlights at the next moment.

[0039] In one exemplary embodiment of this application, the headlights include a left headlight and a right headlight. The step of adaptively adjusting the target illumination angle value of the vehicle headlights based on the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ includes: When the vehicle headlight adjustment device 100 responds to the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ being greater than 0, it adjusts the target illumination angle value of the right headlight to the current vehicle orientation angle value Θ.

[0040] It should be understood that when the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ is greater than 0, it indicates that the navigation direction of the predetermined route automatically generated by the in-vehicle navigation system is to the left of the vehicle's direction of travel. At this time, the vehicle needs to turn left. Therefore, the left headlight can synchronously rotate its illumination direction as the vehicle turns, while the right headlight can adjust its target illumination angle value to the current vehicle orientation angle value Θ through the headlight adjustment device 100. This allows the driver to see the vehicle's direction of travel more clearly when turning, ultimately expanding the driver's field of vision.

[0041] Furthermore, the step in which the vehicle headlight adjustment device 100 responds to the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ being greater than 0 also includes: The current illumination angle value α1 of the vehicle's left headlight is obtained through the vehicle headlight adjustment device 100.

[0042] The vehicle headlight adjustment device 100 determines whether the difference between the current illumination angle value α1 of the left headlight and the current vehicle orientation angle value Θ is less than 0.5 times the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ.

[0043] If α1-Θ<0.5Ψ, then the target illumination angle of the vehicle's left headlight is adjusted by the vehicle headlight adjustment device 100 to be the current vehicle orientation angle value Θ plus 0.75 times the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ, that is, the target illumination angle value of the vehicle's left headlight is Θ+0.75Ψ.

[0044] If α1-Θ≥0.5Ψ, then the target illumination angle value of the left headlight should be kept in real time to follow the vehicle's orientation angle value, so as to minimize the frequency of headlight adjustment and save energy.

[0045] In one exemplary embodiment of this application, the headlights include a left headlight and a right headlight. The step of adaptively adjusting the target illumination angle value of the vehicle headlights based on the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ includes: Figure 4 This is a schematic diagram of the current illumination area of ​​the headlights of a vehicle when it is making a right turn, as shown in this application. Figure 5 This is a schematic diagram of the illumination area at the next moment when the vehicle is making a right turn without adjusting the illumination angle of the headlights, as shown in this application. Figure 6This is a schematic diagram of the illumination area at the next moment when the vehicle is making a right turn and adjusting the illumination angle of the left headlight, as shown in this application; combined with Figures 4 to 6 As shown, when the difference between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ is less than 0, the vehicle headlight adjustment device 100 adjusts the target illumination angle value of the left headlight to the current vehicle orientation angle value Θ.

[0046] It should be understood that when the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ is less than 0, it indicates that the navigation direction of the predetermined path automatically generated by the in-vehicle navigation system is to the right of the vehicle's direction of travel. In this case, the vehicle needs to turn right. Therefore, the right headlight can synchronously adjust its illumination direction as the vehicle turns, while the left headlight can adjust its target illumination angle value to the current vehicle orientation angle value Θ via the headlight adjustment device 100. This allows the driver to see the vehicle's direction of travel more clearly during the turn, ultimately expanding the driver's field of vision.

[0047] Furthermore, Figure 7 This is another schematic diagram showing the current illumination area of ​​the headlights of a vehicle when making a right turn, as illustrated in this application. Figure 8 This is a schematic diagram of the current illumination area of ​​a vehicle when it is making a right turn without adjusting the headlights, as shown in this application. Figure 9 This is a schematic diagram of the illumination area at the next moment when the vehicle is making a right turn and adjusting the illumination angles of the left and right headlights, as shown in this application; combined with Figures 7 to 9 As shown, the step in which the vehicle headlight adjustment device 100 responds to the navigation orientation angle value Ω and the current vehicle orientation angle value Θ being less than 0 further includes: The current illumination angle value α2 of the right headlight of the vehicle is obtained by the vehicle headlight adjustment device 100.

[0048] The vehicle headlight adjustment device 100 determines whether the difference between the current illumination angle value α2 of the right headlight and the current vehicle orientation angle value Θ is less than 0.5 times the difference between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ.

[0049] If α²-Θ>0.5Ψ, combined with Figures 7 to 9 As shown, the target illumination angle of the vehicle's right headlight is adjusted to be Θ, plus 0.75 times the difference Ψ between the current vehicle orientation angle value Θ and the navigation orientation angle value Ω; that is, the target illumination angle of the vehicle's right headlight is Θ + 0.75Ψ. If α2-Θ≤0.5Ψ, then keep the target illumination angle value of the left headlight following the vehicle's orientation angle value in real time, and minimize the frequency of headlight adjustment to save energy.

[0050] In one exemplary embodiment of this application, the headlights include a left headlight and a right headlight. The step of adaptively adjusting the target illumination angle value of the vehicle headlights based on the difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ includes: When the difference between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ is equal to 0, the vehicle headlight adjustment device 100 keeps the target illumination angle values ​​of the left and right headlights following the current vehicle orientation angle value in real time.

[0051] It should be understood that when the vehicle headlight adjustment device 100 responds to a difference Ψ between the navigation orientation angle value Ω and the current vehicle orientation angle value Θ equal to 0, it indicates that the navigation direction of the predetermined path automatically generated by the in-vehicle navigation system is directly ahead of the vehicle's direction of travel. In this case, the vehicle needs to proceed straight. Therefore, the right headlight and left headlight can follow the current vehicle orientation angle value Θ in real time at the next moment.
