Abstract

The invention provides a vehicle headlamp control method, a vehicle headlamp control system and a vehicle. The method comprises the following steps: obtaining a vehicle front image; recognizing a laneline according to the vehicle front image, and determining a vanishing point according to the lane line; judging whether a curve exists in front or not and judging the direction of the curve according to the position change of the vanishing point; determining a curvature of the curve according to the offset of the position change of the vanishing point; and controlling the light sources to be turned off and turned on and adjusting the brightness according to a distance between the vehicle and the curve, the curvature of the curve and the direction of the curve after the headlamp is turned on.The vehicle headlamp control method can judge whether the curve exists in front of the vehicle or not and the curvature and the curve direction of the curve in advance, so that the headlamp can be controlled in advance, and the curve area is illuminated, thereby the driving safety is improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a vehicle headlight control method, system and vehicle. Background technique [0002] Smart headlight systems are being used more and more in vehicles. Smart headlights can be turned on automatically according to light intensity, etc., and can also perform anti-dazzling functions based on recognized targets, but there are the following technical problems: [0003] When there is a curve in the road ahead, the smart headlights cannot illuminate the curve. Therefore, before the vehicle enters the curve, there are potential safety hazards, which will affect driving safety. Contents of the invention [0004] The present application aims to solve at least one of the above-mentioned technical problems. [0005] Therefore, an object of the present application is to propose a method for controlling headlights of a vehicle. This method can pre-judge whether there is a cu...
