Abstract: This application provides a method for determining an automatic parking strategy. The method includes: determining, a target parking action corresponding to a current parking stage performing the target parking action; obtaining feedback information, where the feedback information is used to indicate whether a result of performing the target parking action reaches a predetermined objective, and the predetermined objective is a predetermined position of the vehicle relative to a target parking spot, and/or the predetermined objective is a status of the vehicle in the parking process; and updating the automatic parking strategy based on the feedback information. In the foregoing method, the entire parking process is divided into several parking stages, and a control strategy is obtained by using a different method at each stage. This can increase a success rate of automatic parking in a complex parking scenario.

Abstract: In the method for optimizing decision-making regulation and control, a first traveling sequence is obtained, where the first traveling sequence includes a first trajectory sequence of the vehicle in information about a first environment and first target driving behavior output by a behavior decision-making layer of a decision-making and control system based on the information about the first environment. A second traveling sequence is obtained, where the second traveling sequence includes a second trajectory sequence output by a motion planning layer of the decision-making and control system based on preset second target driving behavior and the second target driving behavior. The behavior decision-making layer is optimized based on a difference between the first traveling sequence and a preset traveling sequence, and the motion planning layer is optimized based on a difference between the second traveling sequence and the preset traveling sequence.

Abstract: A vehicle control apparatus and method includes, when a self-driving vehicle is in a self-driving status, obtaining driving status information of the self-driving vehicle and first driving environment information of the self-driving vehicle; calculating a coarse-grained control instruction of the self-driving vehicle based on the driving status information, the first driving environment information, and a control instruction decision model; determining, based on second driving environment information, whether the coarse-grained control instruction is to be executed; and when the coarse-grained control instruction is to be executed, determining, based on lane information and the driving status information of the self-driving vehicle, a fine-grained control instruction corresponding to the coarse-grained control instruction.
