Electric vehicle lane control system and intersection control method based on vehicle-road interaction coordination

Abstract

The invention discloses a road occupancy management and control system for electric vehicles based on vehicle-road interaction coordination, which includes a motor vehicle vehicle-mounted mechanism, an electric vehicle vehicle-mounted mechanism, and a junction mechanism arranged at each junction. The junction mechanism includes a traffic signal light device, a ground The induction coil controller, the ground induction coil of the motor vehicle and the ground induction coil of the electric vehicle; the vehicle-mounted mechanism includes the vehicle ECU and the vehicle radar, and the vehicle ECU is connected with the vehicle magnetic detection sensor, the vehicle battery, the radar controller and the network coordinator . The vehicle-mounted mechanism of the electric vehicle includes an electric vehicle ECU, and the electric vehicle ECU is connected with an electric vehicle magnetic detection sensor, an electric vehicle battery, an angle sensor and a wireless router. The invention also discloses a corresponding intersection management and control method. The present invention establishes a tripartite interaction between the motor vehicle, the electric vehicle and the road facilities at the intersection, which ensures that the right of passage of the motor vehicle at the intersection is not violated by the flexible and maneuverable electric vehicle, and at the same time avoids unnecessary congestion caused by management and control.

Description

technical field [0001] The invention relates to the technical field of road traffic management and control, in particular to a management and control system and method based on vehicle-road interaction coordination. Background technique [0002] With the increasing speed of urban construction and development, the urban traffic situation is becoming more and more serious, and traffic accidents are becoming more and more frequent. Especially, electric vehicles are an important part of urban public transportation, and the conflict between motor vehicles and electric vehicles is becoming increasingly apparent. [0003] Electric vehicles waiting for traffic lights at traffic intersections beyond the zebra crossing, or directly crossing the red lights will cause motor vehicles to avoid electric vehicles, which will greatly reduce the traffic efficiency at the intersection and aggravate the traffic chaos at the intersection. Due to the small size of electric vehicles, wide field of...

AI Technical Summary

Problems solved by technology

The above-mentioned existing control measures do not carry out tripartite interaction among road facilities such as motor vehicles, electric vehicles, and signal lights, and motor vehicles do not participate in it. When there are no motor vehicles at the intersection and there are many electric vehicles, the electric vehicles will still be controlled by cutting off the power. It is not possible to only record but not control

Like this, when there is no motor vehicle at intersection and electric vehicle is a lot, above-mentioned existing method can increase the weight of the congested phenomenon of intersection, can not alleviate traffic pressure effectively

Because motor vehicles are not involved, when there are no motor vehicles at the intersection, the existing management and control methods cannot be punished afterwards, but can only be restricted on the spot, so it may cause the intersection that was not congested to become congested due to control, causing Many electric vehicles stop at the intersection, which affects the smooth passage of subsequent arriving motor vehicles
