摘　　要：提出了全时四轮驱动汽车驱动轮牵引力综合控制策略。建立了全时四轮驱动汽车驱动动力学模型,应用MATLAB/Simulink设计了驱动轮牵引力控制软件在环仿真系统,并对四轮驱动越野汽车特种工况进行了软件在环仿真模拟。仿真结果表明:设计的控制策略可有效消除驱动轮过度滑转现象,明显改善车辆在对接路面和单轮在低附着系数路面上的牵引性能。An integrated control strategy of the driving-wheel traction was proposed for the full-time four-wheel-drive(4WD) vehicle,and its dynamics model was established.A software-in-the-loop simulation system for the driving-wheel traction control was developed using MATLAB/Simulink,and the software-in-the-loop simulation was performed for the off-road 4WD vehicle at special conditions.The simulation results show that the excessive slippage of the driving-wheel could be avoided by the developed traction control st...
