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

Embodiment 1

[0044] This embodiment is based on the following assumptions:

[0045] (1) The embodiment is in the environment of the expressway Internet of vehicles interconnected with vehicles, and each vehicle is connected by a dedicated short-range communication (DSRC may be used as an example) technology, and the communication range is 300 meters, which can exchange their own status information in real time;

[0046] (2) The speed of information transmission and processing is fast enough, which can be considered to be completed instantaneously, and the data packet loss, transmission and processing delay during the process can be ignored;

[0047] (3) The vehicle can perform precise acceleration and deceleration operations according to the control strategy, and strictly abide by the safety distance conditions;

[0048] (4) The time required for the vehicle to change lanes cannot be ignored, but the longitudinal component of its velocity is approximately equal to its velocity;

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

Technical field: [0001] 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. 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 transport...
