The present application discloses a vehicle trajectory prediction method and device, the method comprising: obtaining vehicle expected trajectory data and vehicle controller type; determining the data category of the vehicle expected trajectory data according to the vehicle expected trajectory data; Determine the corresponding Gaussian mixture model according to the data category and the vehicle controller type; predict the actual running trajectory data of the vehicle according to the expected running trajectory data of the vehicle and the Gaussian mixture model. It can be seen that the method provided by the embodiment of the present application establishes different Gaussian mixture models for different types of vehicle controllers, different types of vehicle speed data and vehicle trajectory curvature data, so as to obtain a more accurate vehicle trajectory. In this way, the desired running trajectory of the vehicle obtained from the vehicle control parameters can be corrected according to the specific controller type and specific working conditions, which improves the accuracy of the predicted vehicle running trajectory.
Description
A kind of vehicle running trajectory prediction method and device technical field [0001] The present application relates to the field of vehicle control, and in particular, to a method and device for predicting a vehicle running trajectory. Background technique [0002] In order to ensure the safety of the vehicle in automatic driving, it is necessary to predict the running trajectory of the vehicle in advance. Currently, through The expected running trajectory of the vehicle obtained from the vehicle control parameters is often used to predict the running condition of the vehicle. but in actual In the application, the expected running trajectory of the vehicle has a certain error with the actual running trajectory of the vehicle. This error will affect the Accurate judgment of the location of the vehicle may even lead to an accident. Therefore, how can we more accurately predict the actual operation of the vehicle? Trajectory has become an urgent technical problem...
