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

Abstract

The invention discloses an electric vehicle lane-occupying control system based on vehicle-road interaction coordination. The system comprises a motor-vehicle-mounted mechanism, an electric-vehicle-mounted mechanism, and an intersection mechanism arranged at each intersection. The intersection mechanisms include traffic light devices, ground-sense coil controllers, motor vehicle ground-sensing coils and electric vehicle ground-sensing coils. The motor-vehicle-mounted mechanism includes a motor vehicle ECU and a vehicle-mounted radar; the motor vehicle ECU is connected with a motor vehicle magnetic detection sensor, a motor vehicle storage battery, a radar controller and a network coordinator. The electric-vehicle-mounted mechanism includes an electric vehicle ECU connected with an electricvehicle magnetic detecting sensor, an electric vehicle storage battery, an angle sensor, and a wireless router. In addition, the invention also discloses a corresponding intersection control method.According to the invention, three-side interaction among the motor vehicle, the electric vehicle and the road junction facilities is established, so that the passing permission of the motor vehicle atthe intersection is protected from being violated by the electric vehicle with flexible movement and unnecessary congestion caused by the controlling is avoided.

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
