Problems solved by technology
[0004] First, by establishing an environment model map as a medium for communication between people and vehicles, not only the cost is high, but also the amount of calculation is large, resulting in low efficiency in path planning
[0005] Second, the path planning algorithm has not considered the problem of multiple obstacles when the vehicle is driving in multiple lanes at low speed, resulting in low judgment ability of the target vehicle when encountering complex scenes, thereby reducing the safety of the vehicle during driving

Embodiments of the present disclosure disclose devices, electronic devices, and media for controlling the travel of an autonomous vehicle. A specific embodiment of the method includes: acquiring the initial state information and the final state information set of the target vehicle; generating at least one candidate vehicle trajectory based on the initial state information and the final state information set; determining the at least one candidate vehicle trajectory According to the cost value corresponding to each candidate vehicle trajectory, at least one cost value is obtained; based on the at least one cost value, the candidate vehicle trajectory that meets the preset conditions is selected from the at least one candidate vehicle trajectory as the vehicle trajectory to be optimized; Optimize vehicle trajectories for path optimization to generate target vehicle trajectories. This embodiment improves the efficiency of path planning.
Description
technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to devices, electronic devices and media for controlling the driving of an automatic driving vehicle. Background technique [0002] Automatic driving motion planning technology is one of the core technologies to ensure the safe driving of unmanned vehicles. Its purpose is to plan a safe and smooth driving trajectory for unmanned vehicles. At present, the methods commonly used in path planning for autonomous vehicles include: artificial potential field method and heuristic search algorithm. [0003] However, when the path is planned in the above manner, the following technical problems often exist: [0004] First, by establishing an environment model map as a medium for communication between humans and vehicles, not only the cost is high, but also the amount of calculation is large, resulting in low efficiency in path planning. [0005] Second, the ...
