Abstract

The invention relates to a vehicle lane changing method and device and a medium, and the method comprises the steps: carrying out the lane selection of a plurality of lanes in a current driving road of a vehicle, and determining an initial lane selection result; under the condition that the lane represented by the initial lane selection result is not the lane where the vehicle runs currently, historical lane selection results of the vehicle for the multiple lanes are obtained; determining a target lane from the plurality of lanes according to the initial lane selection result and the historical lane selection result; and changing the lane of the vehicle according to the target lane. The process of determining the target lane is more stable and smoother, unreasonable phenomena such as lane changing regret and repeated lane changing are greatly reduced, and the user experience of lane changing is improved.

Description

technical field [0001] The present disclosure relates to the technical field of automatic driving, and in particular, to a vehicle lane changing method, device and medium. Background technique [0002] The decision-making planning algorithm is a core part of the autonomous driving technology framework, and the lane-changing decision-making algorithm is an important part of the decision-making planning algorithm. The lane-change decision-making methods in the related art mainly include: a lane-change decision-making method based on a car-following / lane-change model, a lane-change decision-making method based on a safe time distance model, and an interactive game-based lane-change decision-making method. However, the lane selection result output by the lane change decision method in the related art is unstable, which may easily lead to unreasonable phenomena such as lane change regret or repeated lane change. SUMMARY OF THE INVENTION [0003] In order to overcome the proble...
