Intersection passing method and device in automatic vehicle following process

Abstract

The invention discloses an intersection passing method and device in the automatic vehicle following process. The method comprises the following steps: obtaining positions of vehicles and sending a local vehicle control signal to a vehicle controller of a local vehicle to realize target vehicle tracking, wherein the positions of the vehicles comprise position of a target vehicle and position of the local vehicle; when the local vehicle tracks the target vehicle, obtaining a current road state through a monitoring device, and sending the current road state to an intelligent terminal for judgment; when the road state is an intersection, receiving a current state of traffic light sent by a traffic light control system and carrying out judgment; when the current state of the traffic light is no passage, obtaining the distance between the local vehicle to a stop line by the intelligent terminal; and when the distance between the local vehicle to the stop line is smaller than a preset value, sending by the intelligent terminal the control signal to the vehicle controller of the local vehicle to reduce the speed of the local vehicle and stop the local vehicle.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method and device for passing an intersection during automatic vehicle following. Background technique [0002] With the development of our country's economy, the number of cars has increased rapidly, which has made urban traffic congestion more and more serious, and also brought huge mental pressure to drivers. At present, there is also car following in the market that uses a single sensor to obtain the vehicle in front and the surrounding environment for assistance. In a sense, it does not reduce the driver's fatigue. In addition, the reliability and safety of autonomous car following are not very good. guarantee. [0003] In recent years, more and more intersections have added traffic light devices. While enhancing the road traffic safety of non-motor vehicles and citizens, the interval between existing traffic lights is very long, and drivers often have to queue for a long t...

At present, there is also car following in the market that uses a single sensor to obtain the vehicle in front and the surrounding environment for assistance. In a sense, it does not reduce the driver's fatigue. In addition, the reliability and safety of autonomous car following are not very good. guarantee

[0003] In recent years, more and more intersections have added traffic light devices. While enhancing the road traffic safety of non-motor vehicles and citizens, the interval between existing traffic lights is very long, and drivers often have to queue for a long time at an intersection. Waiting for a long time is not only a waste of time, but also causes a certain degree of road congestion

Even if the interval is short, the dense traffic lights in a certain area make the vehicle decelerate too frequently, and the stopping and accelerating processes also reduce time efficiency and user experience.
