基于二维模糊控制的汽车智能限滑系统的研究

A Study on Vehicle Skid Control System Based on Intelligent Fuzzy Control

当行驶的汽车在湿滑路面上出现单轮打滑时,因差速器的作用会让所有动力传到打滑车轮,从而导致整车丧失地面牵引力。为解决这个问题,现提出一种基于二维模糊控制的智能限滑分矩系统方案。其原理是:将当前打滑轮上的驱动扭矩值作为输出信号主值,以轮速差和驱动扭矩作为输入的模糊控制器的输出值作为微调量对主值进行修正,修正结果作为限滑扭矩输出,为非打滑车轮分配稳定的扭矩,使汽车获得运动所需的地面牵引力。

For solving the problem of vehicle skid and lossing the traction of ground in wet and slippery roads because of single wheel sliping, an intelligent fuzzy control-based vehicle skid system is proposed, which uses the current drive torque values of the slipping wheel as the main value of the output signal, seeing the fuzzy controller output value as the fine-tuning value for adjusting the main value.
