System for relieving light-reflecting dazzling of wet road surface based on geometric multi-beam LED lamps

Abstract

The invention discloses a system for relieving light-reflecting dazzling of a wet road surface based on geometric multi-beam LED lamps. An opposite vehicle positioning module is used for obtaining the position and distance of an opposite vehicle according to images. A vehicle lamp road surface light-reflecting detection module is used for judging whether vehicle lamp beams of the opposite vehicle generate light reflecting on the road surface or not according to images. The transverse Km and longitudinal Kn of each LED lamp bead and a set of LED lamp beads with the beam directions facing the ground are stored in a memorizer of a lamp bead controller. On the premise of keeping high-beam high-brightness illumination, beams irradiating the opposite vehicle are adaptively switched off according to the position of the opposite vehicle to solve the dazzling problem; whether lamplight reflection exists on the ground or not is judged through the image recognition technology, if yes, it is shown that a vehicle runs on the wet road surface prone to light reflecting, the beams irradiating the ground are controlled to be switched off, the problem of light-reflecting dazzling is solved, the night driving illumination effect is good, the lamplight dazzling problem is effectively solved, and driving is safer.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to a system for reducing reflection and glare on wet road surfaces based on geometric multi-beam LED lamps. Background technique [0002] Headlights are an important part of a car, which can provide lighting for the car when driving in poor light, foggy weather or at night. Compared with the low beam, the light of the high beam is emitted in parallel, the light is concentrated and brighter, and can illuminate higher and farther objects, which is of great help to the driver's sight at night. However, the current phenomenon of abuse of high beams is quite serious. Using high beams at the wrong time will not only improve driving safety, but will cause short-term blindness to oncoming vehicles and pedestrians, and greatly increase the probability of dangerous accidents. . [0003] In order to solve the above technical problems, many high-end cars have begun to be equipped with adapt...

Problems solved by technology

[0004] However, the traditional adaptive far and low beam switching technology only switches the car lights to low beams. The sudden switch from high beams to low beams will greatly shorten the driver's field of vision, especially when the car is driving at high speed. Due to the limited field of view of the low beam, it is difficult for the driver to make a timely prediction of obstacles outside the low beam field of view, and there are still great potential safety hazards

[0005] In addition, in addition to the fact that the high beam itself is likely to cause serious glare to oncoming vehicles, if it is a wet road, the road surface is also prone to reflections, and the high beam is also likely to cause glare to oncoming vehicles after being reflected by the road.
