Document Type and Number:
WIPO Patent Application WO/2020/233495
Kind Code:
A1
Abstract:
An automatic lane changing method and device, and a storage medium. The method comprises: calculating local neighbor features and global statistical features of an automatic driving vehicle at the current moment according to driving information of the automatic driving vehicle at the current moment and movement information of obstacles of all lanes in a sensing range of the automatic driving vehicle (S1101); obtaining a target action instruction according to the local neighbor feature, the global statistical feature, and the current control strategy (S1102), and executing a target action according to the target action instruction (S1103). Hence, on the basis of the local neighbor features, the global statistical features are further introduced to input the current control strategy to obtain the target action indication, the information of the local neighbor obstacle is considered, and the macroscopic situation of the global statistical features is also considered, so that a target action obtained by integrating the information of the local and all road obstacles is the globally optimal strategy action.
