Control method and device for anti-glare lighting system

Abstract

The invention discloses a control method and device for an anti-dazzle illuminating system. The method correlates the time and direction of luminous illumination, the direction of one circle in the horizontal plane of illuminating space is divided into a plurality of parts, meanwhile, the time of each observation period is divided into parts with the number equal to that of the parts of the direction, the direction parts correspond to the time frames one to one, lights emitting light in all the directions emit light and are observed in one or more corresponding time frames according to the site environment and the requirement for correlating the time and direction of the luminous illumination, the relation of the light emitting time frames and the observation time frames of various kinds of lamplight are set, and the lamplight of different purposes can be visible or invisible. The device adopting the control method is composed of an intelligent time frame selection circuit composed of time measuring equipment, direction measuring equipment and a single-chip microcomputer, a dazzle source detector and an actuator. The method and device can effectively prevent dazzle and guarantee driving safety to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of automobile driving safety, in particular to a control method and device for an anti-glare lighting system. Background technique [0002] Time-separated anti-glare lighting system is a hot spot in the study of automotive anti-glare lighting. According to literature records, mechanical light valves were first applied to time-separated anti-glare lighting systems, but the equipment was heavy and impractical; later in the literature, the concept of liquid crystal light valves controlled by electronic control or single-chip microcomputer appeared, compared with the previous ones. , although the hardware has been improved, but limited by its control theory and method, there are the following defects and problems: [0003] 1. Unable to identify and solve the problem of the pulse overlap of the headlights of the other side and one's own side. In the past, the time-separated anti-glare lighting system only divid...

Problems solved by technology

According to literature records, mechanical light valves were first applied to time-separated anti-glare lighting systems, but the equipment was heavy and impractical; later in the literature, the concept of liquid crystal light valves controlled by electronic control or single-chip microcomputer appeared, compared with the previous ones. , although the hardware has been improved, but limited by its control theory and method, there are the following defects and problems:

When the headlight pulses of both sides coincide, in order to avoid the headlight pulse of the other side, the lighting systems of the two vehicles will adopt the same method to change their own lighting time, causing the light pulses of both sides to overlap again, and so on. It is turned on synchronously, resulting in the failure of the anti-glare function

[0004] 2. In actual application, it only suppresses the glare caused by the headlights of the vehicles in front of the car when passing, but cannot suppress the glare caused by the headlights of overtaking vehicles in the rearview mirror.

[0005] The above shortcomings lead to the fact that although the time-separated anti-glare lighting system can play a role in reducing glare to a certain extent, its effect is not obvious, and it is still difficult to avoid danger.
