基于ISMC的四轮毂驱动电动汽车横摆稳定性控制
Yaw stability control of four-wheel hub-driven electric vehicles based on ISMC
摘要
Abstract
To improve the yaw stability of four-wheel hub-driven electric vehicles under extreme driving conditions,a yaw stability two-layer control strategy based on integral sliding mode control was proposed.The upper-level controller was designed to obtain the additional yaw moment required to maintain vehicle stability based on the integral sliding mode control to track the expected values,which were determined by a two degree of freedom vehicle model with the consideration of road adhesion restriction.Meanwhile,the total required longitudinal moment was obtained by employing PID control.The lower-level controller was designed to reasonably distribute the four wheel torque using axle load proportional distribution,and satisfying the additional yaw moment and total required longitudinal moment.Simulation tests were conducted on the MATLAB/Simulink and CarSim co-simulation platform for high and low road adhesion conditions.The results demonstrated that the proposed control strategy could track the expected value well,with a root mean square error of 0.65 deg/s for yaw rate tracking on low adhesion road,effectively enhancing vehicle stability under extreme driving conditions.关键词
