摘　　要：研究了司机转向行为的控制理论模型,并将之与同一汽车的横摆和侧向速度的两个主要模型结合在一起.横摆角速度反馈与电动转向系统结合在一起来改善汽车的操纵稳定性.仿真结果显示了汽车操纵稳定性的提高.One of the contributors to loss of vehicle control is the reduction in tactile feedback from the steering handwheel when driving on wet or icy pavement. This paper develops a control theoretic model of human steering behavior. This model is then combined with a two mass model of the vehicle yaw and lateral velocity dynamics. Yaw rate feedback is then added to the electric power steering system. Simulation results demonstrate the resulting improvement in vehicle stability.
