Automatic driving control method and system based on vehicle-road coordination

Abstract

The invention discloses an automatic driving control method and system based on vehicle-road coordination. The method includes a blind area detection device sending blind area obstacle information to a road end detection device, and the blind area detection device includes a monocular camera and a laser built on an intersection. Radar, blind spot obstacle information includes the type, location and speed of the blind spot obstacle; the roadside detection device receives the blind spot obstacle information and broadcasts it to the OBU installed on the autonomous vehicle; the OBU on the autonomous vehicle will receive the information. Sent to the V2X module of the autonomous vehicle; the V2X module of the autonomous vehicle parses the received information, and sends the parsed information to the autonomous driving control module of the autonomous vehicle. The parsed information includes the type of obstacles in the blind spot , position and speed; the autonomous driving control module of the autonomous vehicle plans the autonomous driving path according to the parsed information. The present invention can improve the safety of the self-driving car.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to an automatic driving control method and system based on vehicle-road coordination. Background technique [0002] The research and development of autonomous driving can bring convenience to people's lives, but frequent safety accidents have also made people soberly aware that there are still some safety risks in autonomous driving. In related cases, in the Tesla accident in the United States, the vehicle judged the white truck as a white cloud; in the Uber test car accident, the vehicle failed to quickly capture the pedestrians who suddenly appeared from the darkness. Both accidents show that current self-driving technology is not safe enough. [0003] Especially for the automatic driving of commercial vehicles and light passengers, at intersections, due to the limited detection ability of the automatic perception system, it is impossible to detect pedestrians and veh...

Both accidents show that current self-driving technology is not safe enough

[0003] Especially for the automatic driving of commercial vehicles and light passengers, at intersections, due to the limited detection ability of the automatic perception system, it is impossible to detect pedestrians and vehicles on the other side of the road. When the vehicle's sensor detects, the brake actuation system has no time to brake within the effective distance
