Abstract
Methods, apparatus, and computer programs stored on a computer-readable storage medium for obstacle avoidance are provided. One example method includes obtaining vehicle information, obstacle information, and a drivable area of a vehicle at a moment t, and processing the drivable area based on the vehicle information and the obstacle information to obtain a potential energy grid map. The method can include obtaining information about a center line of a lane in which the vehicle is currently located, and obtaining a parallel-line track cluster based on the information about the lane center line. The method can include calculating a cost value of each parallel-line track, and performing time-domain filtering on a parallel-line track with a minimum cost value in the parallel-line track cluster to obtain a target track at the moment t specifying a parallel line track that is used by the vehicle to avoid an obstacle.
