Research on autonomous drift control for vehicles

Abstract The stability control of vehicle movement directly affects the safety and reliability of autonomous vehicles. When a vehicle is in extreme conditions, it is easy to lose stability and lead to accidents. Based on the drift control of racing vehicles under extreme conditions, this paper studies the emergency rescue control strategy for autonomous driving vehicles under extreme conditions. An algorithm similar to the drift control ability of racing drivers is designed. By predicting the vehicle’s driving trajectory and combining automatic steering, clutch, and throttle technologies, the vehicle’s active drift control is realized, so that ordinary vehicles can also have the “abnormal drift obstacle avoidance” control effect in corners like professional racing drivers. Even under extreme conditions such as snowy or icy roads, the vehicle can autonomously adjust its body posture and motion state, effectively improving the safety and reliability of autonomous vehicles and ensuring stable operation under challenging driving conditions.
