Abstract

The invention discloses a vehicle-following control method and system based on vehicle-road cooperation. The method comprises the steps of transmitting a vehicle-following instruction to a first vehicle located on a first lane and a second vehicle located on a second lane, and enabling the first lane and the second lane to be different lanes, selecting one lane from the first lane and the second lane as a formation lane according to a preset rule, and by taking the vehicle in the formation lane as a vehicle following center point, calculating the front-back transverse and longitudinal distance, speed, acceleration and driving track of the vehicle in the formation lane, and sending a control instruction to the vehicles on other lanes, so that the vehicles on the other lanes join in the formation lane, and the first vehicle and the second vehicle carry out vehicle following actions in the formation lane. The following automatic driving of a plurality of vehicles can be realized.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a vehicle following control method and system based on vehicle-road coordination. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, automobiles have become one of the indispensable means of transportation for people to travel. Self-driving car is a kind of smart car, which mainly relies on the computer system-based smart driver in the car to achieve the purpose of automatic driving. [0003] The automatic driving technology in the prior art is mainly aimed at a single vehicle. For road conditions such as expressways with relatively single driving routes, how to realize the automatic driving of multiple vehicles is a technical problem to be solved by those skilled in the art. Contents of the invention [0004] In view of the above problems, an object of the present invent...
