提出了一种控制发动机输出力矩和轴间扭矩分配的控制策略，并添加行驶工况识别模块，针对不同工况制定了不同的控制策略，使四轮驱动汽车能够充分利用路面附着系数。以控制驱动车轮滑移率为目标，在TESIS－DYNAware中建立发动机节气门控制模型及轴间转矩分配系统控制模型，并进行有无牵引力控制系统的直线加速对比仿真试验。试验结果表明，所建牵引力控制策略可有效抑制驱动轮滑转，提高汽车动力性能。

A strategy which controls the output of engine torque and the distribution between the axle torques was proposed to fully use the road friction.The switch model of dynamic condition was established;which contains different strategy to control the vehicle.A dynamic model on four-wheel-drive vehicle was established in TESIS -DYNAware.It was a real time simulation platform.Through modifying and establishing the Simulink model of engine control and inner-axle torque control, a simulation test was running with and without the control system.The result shows that Torque Control System ( TCS) can restrain the slip rate of the drive wheels.
