Title:
METHOD AND APPARATUS FOR DETERMINING OPTIMAL TRAVELING TRAJECTORY OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/201952
Kind Code:
A1
Abstract:
A method and apparatus for determining an optimal traveling trajectory of a vehicle. The method comprises: when an optimal traveling trajectory needs to be updated, acquiring a position of an obstacle around a target vehicle and a vehicle speed of the target vehicle (101); inputting the position and the vehicle speed into a pre-trained machine learning model, so as to obtain a first area (102), wherein the first area is an area which does not comprise the obstacle; constructing a solving function according to a start state, an end state and a comfort index requirement of the target vehicle (103); and determining an optimal traveling trajectory of the target vehicle in the first area according to the solving function (104). The calculation resources used can be reduced, and the calculation time can be shortened.
