Abstract

The invention provides a vehicle trajectory prediction method, a control device and an unmanned vehicle, and relates to the technical field of unmanned driving or automatic driving. The vehicle trajectory prediction method comprises the following steps: acquiring information of a road section where a target vehicle is located and driving information of the target vehicle; judging a driving trend of the target vehicle according to the road section information and the driving information, and obtaining a predicted driving track of the target vehicle according to the driving trend. According to the vehicle trajectory prediction method, the driving information of the target vehicle can be judged according to different road section information, different driving trends expressed when the targetvehicle expresses the same driving information on different road sections are effectively distinguished, the predicted driving trajectory of the target vehicle is correspondingly obtained, and the prediction accuracy of the driving trajectory of the target vehicle is higher; the current vehicle can correspondingly plan the own driving route according to the predicted driving track, so the drivingsafety is higher.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a vehicle trajectory prediction method, a control device and an unmanned vehicle. Background technique [0002] In the application process of automatic driving, the current vehicle needs to predict the trajectory of the surrounding vehicles, and adjust the driving state and driving route of the current vehicle according to the predicted driving trajectory to plan a reasonable driving trajectory; however, the existing current vehicle The trajectory prediction accuracy of surrounding vehicles is poor, and the current vehicle is prone to collide with surrounding vehicles during driving. Contents of the invention [0003] The object of the present invention includes providing a vehicle trajectory prediction method, a control device and an unmanned vehicle to solve the problem that the current vehicle has poor trajectory prediction accuracy for surrounding vehicles and the...
