Problems solved by technology

However, it is difficult for the self-driving vehicle to take into account the actual situation of the road surface in advance when driving according to the pre-planned route. It may be due to the inclination of the road surface, small obstacles on the road surface, slippery road surface, etc. Deviated from the original planned path, which seriously affected the driving accuracy

Abstract

The invention provides a driving planning method and device for an automatic driving vehicle and the automatic driving vehicle, and relates to the technical field of automatic driving. The driving planning method comprises the steps of obtaining a global planning path of the automatic driving vehicle; segmenting the global planning path to obtain a plurality of segmented planning paths; controlling the automatic driving vehicle to travel according to each segmented planning path in sequence, and monitoring deviation condition data of the automatic driving vehicle at the end point of each segmented planning path; and re-planning the global planning path of the automatic driving vehicle according to the deviation condition data of the automatic driving vehicle. Therefore, the driving condition of the automatic driving vehicle can be considered in real time, the automatic driving vehicle is prevented from seriously deviating from the originally planned path, and the driving accuracy of the automatic driving vehicle can be ensured.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a driving planning method and device for an automatic driving vehicle and the automatic driving vehicle. Background technique [0002] At present, before the self-driving vehicle drives, it first needs to plan the path according to the starting point and the end point of the self-driving vehicle, and then control the self-driving vehicle to drive according to the planned path until the end point. However, it is difficult for the self-driving vehicle to take into account the actual situation of the road surface in advance when driving according to the pre-planned route. It may be due to the inclination of the road surface, small obstacles on the road surface, slippery road surface, etc. When it deviates from the originally planned path, it seriously affects the driving accuracy. [0003] It can be seen that how to provide an accurate driving planning schem...
