Control method for automotive headlights

Abstract

The invention discloses a control method for head lights of an automobile. The control method comprises the following steps: 1, collecting current external environment light intensity, and turning on the head lights under the condition that the external environment light intensity is lower than preset environment light intensity; 2, collecting a current distance value S between an obstacle in front of the automobile and the automobile, turning on full-beam headlights of the head lights under a condition that the distance value is greater than preset distance, and turning on dipped headlights of the head lights under the condition that the distance value is less than the preset distance; and 3, collecting a current steering wheel angle value gamma, a current running speed value v and a yaw velocity omega of the automobile, and calculating to obtain a rotation angle theta1 of rotation of the full-beam headlights or dipped headlights of the head lights in a horizontal direction by use of a following formula, wherein the initial orientation of the full-beam headlights or dipped headlights is the same as the length direction of an automobile body, v' is equal to cos(gamma / N), and theta 1 is equal to 90*S*omega / (pi*v'). The control method for the head lights of the automobile is capable of being used for solving the problem that illumination angle adjustment cannot be realized since the head lights easily generate blind zones in the prior art.

Description

technical field [0001] The invention relates to the field of intelligent control of automobile electronic lighting systems, in particular to a control method for automobile headlights. Background technique [0002] Now there are more and more cars in our country, but the condition of the roads is uneven, and the road system is not perfect yet. At present, there are more and more researches on the intelligent control of automobiles, especially the modern intelligent control automobiles integrated with CAN bus and other field buses are also developing in a more intelligent, humane and safe direction. [0003] With the popularization of intelligent energy-saving vehicles, the safety of road driving has also been deeply rooted in the hearts of the people, so the intelligent requirements for automobile headlights are also getting higher and higher. After so many years of development, the car headlight system has made great progress. The headlight is mainly composed of high beam ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a control method for automobile headlights, which overcomes the problems that the headlights in the prior art tend to have blind spots and cannot realize the adjustment of the illumination angle. It greatly improves the utilization efficiency of the headlights, has high intelligence and timely control, and enhances the ability of the car to adapt to complex roads
