The present application provides a driving trajectory generation method, device and storage medium, the method is suitable for the hot standby module in the vehicle control system, the vehicle control system includes: a main control module and a hot standby module, wherein the method includes: When the main control module is working abnormally, obtain a reference information set, the reference information set includes: lane line information, obstacle information, and vehicle status information of at least one vehicle, and generate a driving schedule for the self-driving vehicle according to the effective reference information in the reference information set. track, the valid reference information is reference information with a confidence level higher than a preset threshold. In this technical solution, the hot backup module generates a driving trajectory based on the obtained reference information set, and the driving trajectory can be used to control the safe driving of the self-driving vehicle, which solves the potential safety hazard that may occur when the on-board control system of the self-driving vehicle fails.
Description
Technical field [0001] The present application relates to the field of automatic driving technology, and more particularly to a driving trajectory generation method, a device, and a storage medium. Background technique [0002] The automatic driving vehicle is also known as an unmanned vehicle. It is a smart vehicle that implements unmanned driving through the computer system. It relies on artificial intelligence, visual computing, radar, monitoring device and the global positioning system to cooperate with the global positioning system, so that the computer system of the vehicle can be Automatically operate vehicle in the case of unmanned operation. [0003] In the prior art, the automatic driving vehicle may fail to fail during driving, resulting in an abnormal driving behavior of the automatic driving vehicle, there is a hidden danger of traffic accidents. Thus, there is an urgent need to propose a method to solve the security hazards that may occur when the vehicle control sy...
