Self-adaptive headlamp control method, terminal equipment and storage medium

Abstract

The invention relates to a self-adaptive headlamp control method, terminal equipment and a storage medium. The method comprises the steps: determining a safe sight distance corresponding to the current position of a vehicle according to the current speed of the vehicle; calculating a view inclination angle difference of each slope point relative to the current position of the vehicle within the safe sight distance by combining front electronic horizon data; starting from the farthest slope point in the safe sight distance, sequentially screening the slope points from far to near until the view inclination angle differences corresponding to all the slope points between the screened slope point and the current position of the vehicle belong to the illumination angle range corresponding to the screened slope point; and adjusting the irradiation angle by taking the view inclination angle difference corresponding to the screened slope point as the vertical adjustment angle of the self-adaptive headlamp. According to the invention, the electronic horizon line technology is combined, road slope information outside the view is provided, the vertical angle control is optimized, the problem of illumination blind areas caused by slope change due to simple angle control can be prevented, and the adaptive headlamp control of the slope terrain is more adapted.

Description

technical field [0001] The invention relates to the field of vehicle intelligent control, in particular to an adaptive headlamp control method, terminal equipment and a storage medium. Background technique [0002] Adaptive Front Lighting (AFS) technology requires changing the horizontal and vertical angles of lighting according to the vehicle environment. The usual method is to adjust the horizontal front lighting angle through the data collected by the steering wheel steering sensor, or to adjust the vertical front lighting angle through the vehicle body tilt sensor. However, the sensor can only obtain the current state of the vehicle environment, but cannot obtain the data of the road environment in front of the vehicle, and has no predictability for the road ahead. The most important thing for the lighting system is to ensure the brightness of the front, so the traditional control method cannot achieve the best effect.

Problems solved by technology

However, ordinary navigation maps do not have road slope information, and have no optimization effect on vertical angle control

And when the terrain is a hillside terrain, if only a simple angle control is performed, there will also be a blind spot problem caused by the slope change, such as figure 1 The irradiation angle is selected according to the slope S of the current vehicle location, because the blind area of ​​irradiation appears due to the change of the slope ahead; figure 2 Shown is to select the illumination angle according to the slope S of the farthest position of the expected lighting, because there is a slope change between the current position of the vehicle and the actual position cannot be illuminated to the expected position, resulting in a blind spot
