Abstract

The invention provides an intersection precise parking device and method used for automatic driving. The device comprises an image acquisition device, an electronic control unit, millimeter-wave radar and a speedometer. A camera is used for acquiring images of zebra crossing and a stop line in a road and traffic lights above the road. The millimeter-wave radar is used for detecting front vehicle information. The electronic control unit can detect the zebra crossing, the stop line and the traffic lights and can estimate the distance between a vehicle and the stop line according to pulse number fed back by the speedometer when the stop line enters a camera view dead zone, and the automatically driven vehicle can be precisely parked at the stop line of an intersection. When a vehicle is in front of the current vehicle, the electronic control unit can achieve precise parking according to data detected by the millimeter-wave radar, the position of the front vehicle and the states of the traffic lights. The device and method solve the problem about how to precisely park the automatically driven vehicle at the stop line at the intersection.

Description

technical field [0001] The present invention relates to a parking device and method in the technical field of transportation, in particular to a precise parking device at an intersection for self-driving vehicles, and a corresponding implementation method of the device. Background technique [0002] With the rapid development of modern society and economy, automobiles have become an important means of transportation for people to travel. With the increasing number of vehicles, traffic pressure is also increasing, and traffic accidents are becoming more frequent. In order to reduce the human factors in traffic accidents, vehicle automatic driving technology has become an important research hotspot. Due to its complex traffic scenes and strict traffic rules, urban traffic has become a difficult point in the field of autonomous driving research. Among them, intersections are places where traffic flows from all directions meet. It is an important guarantee to ensure the smooth...
