A non-forced lane-changing control method for expressway vehicles in the Internet of Vehicles environment

Abstract

The invention discloses a highway vehicle non-forced lane changing control method under the environment of internet of vehicles. Non-forced lane changing is the behavior that a lane changing vehicle changes to the nearby lane of better traffic state to drive to improve the vehicle driving state and the driving speed of the front vehicle is low. The method comprises the steps that the vehicle driven on the highway can implement vehicle-vehicle communication and perform real-time data exchange with surrounding vehicles within the communication range through a wireless communication mode under the environment of internet of vehicles; and when a certain vehicle has a non-forced lane changing demand, the vehicle transmits a request to the surrounding vehicles to acquire position and speed information of other vehicles, judgment is performed according to different traffic states within the communication range around the vehicle, the forced lane changing behavior of the lane changing vehicle is controlled and thus safe and efficient implementation of the non-forced lane changing behavior can be realized. The state of the lane changing vehicle and other relevant vehicles is analyzed and the non-forced lane changing behavior of the vehicle is reasonably organized accordingly so that safe and efficient implementation of the non-forced lane changing behavior can be realized.

Description

Technical field: [0001] The invention relates to a vehicle cooperative driving control method, in particular to a control method for non-forced lane changing of expressway vehicles under the Internet of Vehicles environment. Background technique: [0002] 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 intelligent trans...

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
