摘　　要：采用ADAMS与MATLAB耦合仿真的方法,将电动助力转向控制与整车模型相结合,进行了助力特性补偿策略的仿真研究,解决了多体动力学自由度过多和控制运算法则过于复杂两者共处的问题。通过对助力特性进行补偿调节,提高了汽车的行驶稳定性。The co-simulation method with ADAMS and MATLAB is adopted to pe rform the simulation analysis on compensation strategy of assist characteristic for el ectric power assisted steering (EPAS) by combining vehicle model (in ADAMS) and EPAS control model (in MATLAB), overcoming the problem of too many degrees of fr eedom in multi-body dynamics model and over complex control algorithm. Through t he adjustment and compensation of assist characteristics, the driving stability of vehicle is enhanced and the ride comfort is improved.
