Abstract

The present invention provides a trajectory planning method, system, device and storage medium; the method includes: analyzing the environment information corresponding to the environment where the vehicle is located to obtain the driving scene where the vehicle is located; according to the driving scene where the vehicle is located, the corresponding selection performance is prioritized Or the trajectory planning mode with priority on efficiency is the target trajectory planning mode; according to the target trajectory planning mode, determine the path from the initial position of the vehicle to the target position, and determine the speed curve from the initial position of the vehicle to the target position; the determined The path and speed curve are synthesized to obtain the trajectory used by the vehicle from the starting position to the target position. The invention can adapt to different driving scenarios to plan the trajectory of the automatic driving of the vehicle.

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...
