四轮驱动汽车牵引力控制系统研究

Research on traction control system for four wheel drive vehicle

在确定四轮驱动汽车牵引力控制系统硬件方案和控制策略的基础上,设计了控制软件及控制系统;建立了四轮驱动汽车加速过程的数学模型;对弱附着地面、分离路面及松散沙地上的牵引力控制过程进行了仿真模拟。结果表明:牵引力控制系统能有效抑制驱动轮过度滑转。

A traction control system for four wheel drive vehicle is presented in this paper. According to the project of hardware and control strategy given, a control software is designed. The mathematical models of accelerating process are established and control systems are also designed. A computer simulation is made on lowμ road, splitμ road and loose sand. The results indicate that the traction control system can prevent the wheel excess spinning on the three above roads effectively.
