Abstract

The present application provides a parking control method and device for an automatic driving truck, and the automatic driving truck, which relate to the technical field of automatic driving. The method includes: obtaining a parking task instruction; the parking task instruction includes a location to be parked; determining the global planning path of the self-driving truck according to the location to be parked; segmenting the global planning path to obtain multiple segments Plan the path; control the self-driving truck to drive according to each segment planning path in turn, and monitor the deviation data of the self-driving truck at the end of each segment planning path; re-plan the self-driving truck’s route according to the deviation data of the self-driving truck Globally plan the path until the self-driving truck is controlled to the location to be parked. The embodiment of the present application can consider the driving situation of the self-driving truck in real time, avoid the self-driving truck from seriously deviating from the originally planned route, and ensure the parking accuracy of the self-driving truck.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a parking control method and device for an automatic driving truck and the automatic driving truck. Background technique [0002] At present, self-driving trucks generally include two parts: a tractor and a trailer, and the tail of the tractor is connected to the head of the trailer. Before the self-driving truck drives, it first needs to plan the path according to the starting point and the end point of the self-driving truck, and then when the self-driving truck is driving, the tractor is controlled to drive the trailer to move, so as to drive according to the planned path until end. However, it is difficult for self-driving trucks to take into account the actual conditions of the road in advance when driving on a pre-planned route. It may be due to the slope of the road, small obstacles on the road, and slippery roads, which may cause the self-driving ...
