基于相平面法的智能汽车路径跟踪和稳定性控制
Path tracking and stability control of intelligent vehicles based on phase plane approach
摘要
Abstract
To improve the dynamic stability of vehicles during operation,a phase plane analysis model is built based on key parameters such as the slip angle,yaw rate,and slip angle velocity.The model enables real-time evaluation and control of vehicle stability.First,longitudinal and lateral controllers are developed to ensure the accuracy of the vehicle's trajectory.A hierarchical control strategy is then designed to address instability during driving.Using desired values for slip angle and yaw rate as control objectives,appropriate active stability control measures are applied according to different stability states of the vehicle,ensuring the vehicle remains stable.Co-simulation with Carsim and Simulink is employed to test the stability assessment methods and integrated control strategies under two high-risk conditions:closed-loop double-lane change and open-loop sine steering.The simulation results demonstrate the proposed stability judgment and control strategy effectively suppresses vehicle instability in extreme conditions,improving driving stability.关键词
