摘　　要：设计了基于变速器挡位控制与发动机输出转矩联合控制的牵引力控制策略,并给出了控制流程。建立了车辆起步加速过程的动力学模型,应用Matlab软件建立了仿真模型。对车辆在冰雪路面上的起步加速过程进行了仿真研究。仿真结果表明,基于发动机及自动变速器联合控制的TCS策略能够有效控制驱动轮的滑转率,提高车辆在冰雪路面上的起步加速性能,为后期的控制器设计提供了一定的理论依据。TCS strategy based on integrated control of engine torque and automatic transmission gear was designed, and then the control logic was proposed. The dynamic model of vehicle starting and accelerating process was built, and the simulation model was established with Matlab. Some simulations of vehicle running on icy and snowy road were processed. The results indicated that the TCS strategy based on integrated control of engine and automatic transmission could control the slippage ratio of the driven wheel effectively, thus the capability of vehicle starting and accelerating on icy and snowy road has been increased. The study provided some theoretical reference to the consecutive research.
