Embodiment

[0059] This embodiment is based on the following assumptions:

[0060] (1) The embodiment is in the environment of the Internet of Vehicles, and a central controller is set at an unsignalized intersection, and the required information can be transmitted through vehicle-vehicle communication and vehicle-road communication;

[0061] (2) The speed of information transmission and processing is fast enough compared to the speed of the vehicle, and the delay in the process is negligible;

[0062] (3) The vehicle can drive accurately and automatically under the control of the central controller;

[0063] (4) The communication range of the central controller is large enough to realize the process of coordinated control of the main road and branch road vehicles;

[0064] (5) The impact of pedestrians and non-motor vehicles is not considered.

[0065] In order to realize the coordinated control of vehicles on the main road and branch roads, the distance before the stop line at the int...

Abstract

The invention discloses a method for vehicle cooperative control at a non-signaled intersection in a vehicle networking environment. By adopting the method, cooperative control on vehicles on a main road and a branch road is realized on the basis of ensuring priority pass of the vehicles on the main road. Speed keeping lines and clearance search lines are arranged on the main road and the branch road respectively. When a vehicle on the main road reaches the range of a center controller, the center controller makes a driving strategy for the vehicle according to the principle of priority pass of the vehicles on the main road to enable the vehicle to run at the speed Vmax set for the main road behind the speed keeping line until the vehicle crosses the intersection. When a vehicle on the branch road reaches the clearance search line, the vehicle on the branch road sends a clearance search request to the center controller, the center controller makes a driving strategy for the vehicle according to the acquired information, and the vehicle on the branch road runs through the intersection according to the driving strategy. The method of the invention not only is helpful to the development and application of the vehicle networking technology, but also has significant implications for the improvement of traffic efficiency and safety at non-signaled intersections.

Description

technical field [0001] The invention relates to the research field of vehicle control technology at road intersections, in particular to a method for cooperative control of vehicles at unsignalized intersections under the Internet of Vehicles environment. Background technique [0002] Unsignalized intersections are an important part of the road network. At present, the control of vehicles at unsignalized intersections mainly relies on basic road traffic safety regulations and the principle of "give way on slip roads". The so-called "bypass" principle means that the driver of the vehicle on the bypass subjectively judges whether the gap between vehicles on the main road is acceptable and chooses whether to pass. This subjective factor makes the traffic characteristics of unsignalized intersections more complex, and the safety level is lower than that of signalized intersections. [0003] With the continuous development of wireless communication technology and intelligent veh...
