[0002] With the rapid development of science and technology, the field of intelligent transportation has made significant progress. As a key part of it, autonomous driving technology has attracted much attention in recent years and has made continuous breakthroughs; early autonomous driving technology research mainly focused on basic environmental perception and vehicle control algorithms, such as using simple radars and cameras to achieve vehicle adaptive cruise control and simple obstacle avoidance; over time, technology has gradually developed towards higher levels of autonomous driving, integrating a variety of sensor technologies, such as lidar, millimeter-wave radar, cameras, etc., to improve the accuracy and reliability of environmental perception; at the same time, the rapid development of technologies such as big data, artificial intelligence and cloud computing has also provided autonomous driving technology with powerful data processing and decision support capabilities, enabling vehicles to achieve autonomous driving in more complex traffic scenarios; However, the existing technology still has many problems.

For example, in severe weather conditions or when encountering special-shaped obstacles, the recognition accuracy may drop significantly, affecting the safety of vehicle driving. Although the safety assurance system has developed to a certain extent, its ability to respond to hacker attacks and system failures is still weak. Once there is a problem with the main control system, the switching of the backup system may not be timely or stable enough, posing potential risks to passenger safety. Automatic driving decision models often do not have Fully considering the impact of vehicle passenger capacity on driving speed and obstacle avoidance distance, resulting in the inability to achieve optimal vehicle performance under different passenger loads, which may affect passenger comfort and increase energy consumption and safety hazards; in terms of energy management, there is still room for improvement in charging efficiency and energy recovery rate.
