Abstract

The invention provides a trajectory planning method, system and equipment and a storage medium. The method includes the following steps of: analyzing environmental information corresponding to the environment where a vehicle is located, and obtaining a driving scene where the vehicle is located; according to the driving scene where the vehicle is located, correspondingly selecting a trajectory planning mode with performance priority or efficiency priority as a target trajectory planning mode; according to the target trajectory planning mode, determining a path from the starting position of thevehicle to a target position, and determining a speed curve from the starting position of the vehicle to the target position; and combining the determined path and speed curve to obtain a trajectoryused by the vehicle from the starting position to the target position. The scheme of the invention can be adapted to planning the trajectory of automatic driving of the vehicle in different driving scenes.

Description

technical field [0001] The present invention relates to automatic driving technology, in particular to a trajectory planning method, system, equipment and storage medium. Background technique [0002] As an important application of artificial intelligence, autonomous driving technology has been greatly developed in recent years. The goal of autonomous driving is to enable vehicles to travel along the road autonomously in an unmanned state, to ensure the safety of the vehicle while reaching the destination as soon as possible, and to ensure that it does not cause direct or indirect threats to the safety of other traffic participants. [0003] To achieve the above goals, autonomous driving software requires several key systems, and the trajectory planning system is one of them. The purpose of the trajectory planning system is to plan a trajectory that meets the vehicle dynamics requirements. This trajectory needs to be able to avoid surrounding obstacles (vehicles, pedestria...
