Abstract

The invention discloses a collision avoidance method and system based on traffic light signals and a vehicle, and belongs to the technical field of traffic safety. The collision avoidance method comprises the following steps: acquiring a traffic light signal of an intersection in response to a collision avoidance instruction of a vehicle; when the traffic light signal is a red light signal or a yellow light signal, determining the position of the vehicle; when the vehicle position is located in a collision avoidance working area, acquiring the driving speed of the -vehicle and information of avehicle ahead the -vehicle; and controlling the vehicle to decelerate or brake according to the vehicle position, the vehicle running speed and the information of the vehicle ahead the vehicle. According to the collision avoidance method, deceleration or braking control over the vehicle is achieved according to the road condition information in the driving process of the vehicle, and the drivingsafety of the vehicle at the intersection is improved.
