Abstract

The invention provides a vehicle long-term trajectory prediction method and system in a complex scene. The vehicle long-term trajectory prediction method comprises the steps of: 1, acquiring vehicle state information according to a vehicle-mounted sensor, judging the vehicle state information through utilizing a hidden Markov model to obtain a vehicle driving intention; 2, establishing an acceleration prediction model and acquiring predicted acceleration according to the vehicle driving intention; and 3, iteratively calculating a long-term vehicle prediction trajectory by adopting a uniform acceleration model according to the predicted acceleration. According to the vehicle long-term trajectory prediction method and the system, the GPR prediction track model is provided, the future long-term running trajectory of the vehicle is accurately and effectively predicted, the vehicle long-term trajectory prediction method and the system are suitable for complex scenes, the accuracy and prediction precision of long-term running track prediction of the vehicle are improved, and the high efficiency and safety of vehicle running are enhanced.

Description
