Document Type and Number:
WIPO Patent Application WO/2022/133775
Kind Code:
A1
Abstract:
A trajectory data processing method, comprising: acquiring trajectory data, road information, and route data of a target vehicle within a preset period of time, and road condition data within a preset distance range from the target vehicle; inputting the trajectory data, the road condition data, the road information, and the route data into a data simulation unit, wherein the data simulation unit comprises a current trajectory planning parameter, and generating a simulated trajectory of the target vehicle according to the trajectory data, the road condition data, the road information, the route data, and the current trajectory planning parameter; performing cost computation on the simulated trajectory to obtain a cost value corresponding to the simulated trajectory; and adjusting the current trajectory planning parameter according to the cost value, using the adjusted trajectory planning parameter as the current trajectory planning parameter, and returning to the step of generating a simulated trajectory of the target vehicle according to the trajectory data, the road condition data, the road information, the route data, and the current trajectory planning parameter until a preset condition is satisfied, and stopping the parameter adjustment to obtain a target trajectory planning parameter.
