Device and method for controlling headlamp

Abstract

The invention discloses a device and a method for controlling a headlamp, and relates to the technical field of vehicles. The device and the method can reduce influence of headlights on full beam on vehicles running in an opposite direction, and ensure driving safety of the driver of a vehicle. The device for controlling a headlamp comprises: firstly, an information acquisition portion obtaining current position information and running speed of a vehicle through a navigation system, and obtaining current position information and running speed of an opposite vehicle through a communication system, then a meeting time calculation portion calculating meeting starting time and meeting end time of the vehicle and the opposite vehicle, and finally, a road condition determination portion determining whether a meeting road segment has a central isolation belt, when the road condition determination portion determines that any position of the meeting road segment is provided with the central isolation belt, a headlamp control portion illuminating a front road surface through the headlights on full beam in the meeting road segment. The method and the device are suitable to control the headlamps to illuminate through the headlights on full beam or dipped headlights.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a device and method for controlling headlights. Background technique [0002] With the continuous development of science and technology, automobiles have become a necessary means of transportation in human life. At the same time, traffic accidents caused by bad driving habits of drivers have also increased. For example, when the driver of the car drives the car at night and turns on the high beam lights, when the car meets other cars, the driver of the opposite car cannot see the road clearly due to the strong light from the high beam lights of the car. situation, it will lead to accidents. [0003] In order to solve this problem, a solution is disclosed in the patent application document of Chinese Patent No. 201210056318.2: first, the vehicle sends the current position and driving speed of the vehicle to the other party's vehicle through the communication module, and recei...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned technical scheme can switch the headlights from high beams to low beams in time when meeting cars, in the actual driving process, there is a situation that turning on the high beams of this car will not affect the sight of the driver of the other car. At this time, if the car still switches the headlights from the high beam to the low beam, not only will it not bring any practical effect to the passing car, but it will also cause the driver of the car to be unable to see the road conditions far ahead.
