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

Abstract

The invention discloses an automatic driving control method and system based on vehicle-road cooperation. The method comprises the steps that a blind area detection device sends blind area obstacle information to road end detection equipment, the blind area detection device comprises a monocular camera and a laser radar which are built on a crossroad, and the blind area obstacle information comprises the type, the position and the speed of a blind area obstacle; the roadside detection device receives the blind area obstacle information and then broadcasts the blind area obstacle information toan OBU installed on the automatic driving vehicle; the OBU on the automatic driving vehicle sends the received information to a V2X module of the automatic driving vehicle; a V2X module of the automatic driving vehicle analyzes the received information and sends the analyzed information to an automatic driving control module of the automatic driving vehicle, and the analyzed information comprisesthe type, the position and the speed of a blind area obstacle; and an automatic driving control module of the automatic driving vehicle plans an automatic driving path according to the analyzed information. The safety of the automatic driving automobile can be improved.

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
