Method, device and system for adjusting the inclination angle of headlights of a vehicle

Abstract

The application provides an adjusting method, device and system for a tilt angle of a headlamp of a vehicle. The method comprises the following steps: determining a deflection angle of an axis of the vehicle when the vehicle tilts; determining a current height value of the headlamp according to the deflection angle of the axis of the vehicle and a distance from the headlamp of the vehicle to a front axle; determining an illuminating tilt angle required by the current height value as a currently required illuminating tilt angle according to the current height value of the headlamp and an actually required illuminating distance; and calculating the currently required illuminating tilt angle according to an initial tilt angle of the headlamp, the currently required illuminating tilt angle of the headlamp and the deflection angle of the axis of the vehicle and adjusting the tilt angle of the headlamp according to an angle deserved to be adjusted of the headlamp. According to the application, when the tilt angle of the headlamp is changed as a vehicle body tilts due to dynamic factors such as a road condition and a load change, the tilt angle of the headlamp can be dynamically adjusted in real time, so that the headlamp can meet the requirement of real-time illuminating, and therefore, the travelling safety and comfort can be ensured.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method, device and system for adjusting the inclination angle of a headlamp of a vehicle. Background technique [0002] Usually, the headlights of automobiles are fixed. When the inclination angle of the vehicle body changes due to different loads or changes in driving road conditions, the irradiation angle of the headlights will also change with the pitch of the vehicle body, causing changes in the lighting distance, and even affecting road conditions. Other driving vehicles cause glare, affecting driving safety and comfort. [0003] At present, the most widely used is the static headlight tilt adjustment, that is, to adjust according to the load when the vehicle is stationary. However, the above-mentioned static headlight inclination adjustment cannot be dynamically adjusted in real time for some dynamic situations, such as headlight angle changes caused by ve...
