V2X-technology-based smart traffic light method for vehicle passing intersection

Abstract

The invention, which belongs to the field of intelligent driving technology, relates to a V2X-technology-based smart traffic light method for a vehicle passing intersection so that problems of economic and comfortable reduction and traffic congestion caused by improper driving of the existing intelligent vehicle can be solved. The method comprises: a smart driving function of an intelligent vehicle is enabled; the intelligent vehicle receives position and speed information of the vehicle and a vehicle in front of the intelligent vehicle and traffic light state information simultaneously; a candidate acceleration sequence of the intelligent vehicle is generated and a speed matrix and a position matrix of the intelligent vehicle within a prediction time domain are generated by combining thespeed and position of the intelligent vehicle; according to the position and speed of the vehicle in front of the intelligent vehicle, a speed matrix and a position matrix of the vehicle in front of the intelligent vehicle within a prediction time domain are generated; a total cost corresponding to each candidate acceleration speed of the intelligent vehicle is determined and the candidate acceleration speed with the minimum total cost is used as an expected acceleration speed; and on the basis of the expected acceleration speed and a corresponding expected speed, the intelligent vehicle passes a traffic light at an intersection. Therefore, the intelligent vehicle can passes the traffic light economically and comfortably; and the traffic congestion problem caused by improper driving is solved.
