Embodiment Construction

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] The present invention firstly plans a plurality of global entry paths through the environment map; then selects one of the entry paths, and judges whether there are obstacles on the entry path, if not, then drives according to the entry path; when the selected entry path is When there are obstacles on the station path, judge whether there are obstacles in the rest of the inbound paths one by one, until an inbound path without obstacles is found. The following takes the city bus stop as an example to describe the stop control method of the present invention in detail. The implementation process of the method is as follows: figure 2 As shown, the specific implementation process is as follows.

[0026] 1. Plan at least two global entry paths.

[0027] The present invention plans N global entry paths according to the environment map, a...

Abstract

The invention relates to a method and system for controlling automatic stop of a vehicle, and belongs to the technical field of automatic driving path planning. According to the method and system, byplanning multiple global inbound paths and selecting a corresponding inbound path for stop based on whether obstacles exist in each inbound path, the method and system not only ensure that the selected stop path is a global path, but also ensure that the selected stop path meets the requirements of collision-free, solve the problem of the unreasonable stop position and direction of the currently selected stop path, and optimizes the inbound path during the vehicle stop process.

Description

technical field [0001] The invention relates to a vehicle automatic stop control method and system, belonging to the technical field of automatic driving path planning. Background technique [0002] The path planning of autonomous vehicles is divided into two categories: one is the global path planning based on map information, which is a path that can be passed smoothly based on the prior environment model; the other is local based on the surrounding information of the autonomous vehicle. Path planning, which is to obtain road and obstacle information in real time through its own sensors when the operating environment of the vehicle is partially unknown or completely unknown, and plan a local path to achieve collision-free driving. The task of global path planning is to plan a collision-free and passable path from the starting point to the target point according to the information of the global static map database; the task of local planning is to plan a collision-free path...
