Document Type and Number:
WIPO Patent Application WO/2021/169591
Kind Code:
A1
Abstract:
A vehicle behavior prediction method and apparatus, an electronic device, and a storage medium, relating to the technical field of intelligent driving. The method comprises: obtaining a path that a target vehicle is to travel at a current intersection, and determining a target traffic light corresponding to the path (S210); determining adjacent traffic lights corresponding to the target traffic light and indication states of the adjacent traffic lights according to the target traffic light, an obtained indication state of the target traffic light, and a traffic light state mapping relation table (S220); obtaining the position of an obstacle vehicle, predicting all possible traveling paths of the obstacle vehicle at the current intersection according to the position of the obstacle vehicle, and determining a traffic light corresponding to each possible traveling path (S230); and determining a final possible traveling path of the obstacle vehicle according to all possible traveling paths and the indication state of the traffic light corresponding to each possible traveling path (S240). The method can improve the vehicle behavior prediction accuracy.
