Expressway vehicle compulsory lane changing control method under vehicle networking environment

Abstract

The invention discloses an expressway vehicle compulsory lane changing control method under a vehicle networking environment. The method comprises steps that under the vehicle networking environment, operation information of surrounding vehicles through vehicle-to-vehicle communication is acquired; when a certain vehicle has a compulsory lane changing requirement, the vehicle sends a request to vehicles nearby, and acquires information of positions, speeds and the like of other vehicles; analysis is carried out on different states of the vehicle which changes the lane and other related vehicles; and based on the different states of the vehicle which changes the lane and other related vehicles, compulsory lane changing behaviors of the vehicle which changes the lane are controlled, thereby achieving safe and highly efficient implementation of compulsory lane changing behaviors. The method provides support for auxiliary driving and automatic driving. By analyzing the states of the vehicle which changes the lane and other related vehicles, and carrying out proper organization based on the compulsory lane changing behaviors of the vehicle, safe and highly efficient implementation of compulsory lane changing behaviors is ensured.

Description

[0001] Technical field: [0002] The invention relates to a vehicle cooperative driving control method, in particular to a control method for forced lane-changing of expressway vehicles under the Internet of Vehicles environment. [0003] Background technique: [0004] With the rapid development of the social economy, the number of civilian vehicles in my country has continued to increase. By the end of 2016, the number of civilian vehicles in the country had reached 194.4 million, an increase of 12.8% compared to the end of 2015. However, due to investment and space constraints, the mileage of highways of grade 4 and above in the country only increased by 4.3%, and the mileage of expressway lanes increased by only 5.4%, far from the growth rate of civilian vehicles, resulting in increasing pressure on road traffic. On the basis of not increasing road infrastructure investment on a large scale, with the development of wireless communication technology, the development of intell...

AI Technical Summary

Problems solved by technology

For the third development stage of intelligent networked vehicles, the vehicle can exchange real-time data and cooperate with other vehicles within the communication range, but it cannot achieve complete automatic driving.

In this phase, most of the vehicles in the highway are cooperating in a platoon, but there is bound to be a problem of changing lanes to enter or leave the platoon
