V2X-based self-adaptive high-beam and low-beam control method and system

Abstract

The invention relates to a V2X-based self-adaptive high-beam and low-beam light control method and system, and relates to the technical field of intelligent control of an automobile electronic lighting system. The control method comprises the following steps: obtaining target object information through a V2X technology; identifying a driving scene according to the target object information, wherein the driving scene comprises a reverse meeting scene, a following driving scene and a special road section driving scene; when the driving scene is a reverse meeting scene or a following driving scene, carrying out high-beam and low-beam switching operation; and when the driving scene is a special road section driving scene, carrying out high-beam and low-beam alternate flickering operation. According to the V2X-based self-adaptive high-beam and low-beam control system, the driving scene can be accurately identified, the false triggering probability is reduced, the high-beam and low-beam switching control precision is effectively improved, the driving burden of a driver can be reduced, and the driving safety is guaranteed.

Description

technical field [0001] The present application relates to the technical field of intelligent control of automotive electronic lighting systems, in particular to a V2X-based adaptive high and low beam control method and system. Background technique [0002] At present, when driving, especially at night, drivers often encounter scenes of meeting cars in the opposite direction, following cars, and special road sections (such as slope roads, arch bridges, intersections without traffic lights, etc.), according to the existing traffic rules , at this time, the driver needs to frequently switch between high and low beams to prevent danger. However, frequent high and low beam switching operations not only increase the driver's driving burden, but also cause traffic accidents very easily if the driver fails to switch the high and low beams in time or fails to switch the lights. [0003] Vehicles equipped with an adaptive high and low beam switching system have been launched on the m...

AI Technical Summary

Problems solved by technology

This technology has a certain probability of false detection, and is limited by the weather conditions of the vehicle. In case of heavy rain, heavy snow, heavy fog and other weather, it will affect the judgment of the high and low beam system

In addition, when meeting cars on a curve at night, the camera cannot detect the approaching vehicle at the other end of the curve, so there is a certain degree of traffic hazard

From the perspective of production cost, the cost of using the camera to switch the vehicle's adaptive high and low beams is relatively high, which is not conducive to the development of automobile manufacturers
