摘　　要：针对在某些情况下轴间驱动力分配控制策略的不足,提出了一种能提高四轮驱动汽车操纵稳定性的级联式控制策略。其基本思路是当轴间驱动力分配控制效果不能满足要求或者已经到达控制极限时启用直接横摆力矩控制。仿真结果表明级联式控制策略较轴间驱动力分配控制策略有更强的控制能力,效果明显。In view of the defect of inter-axle driving force distribution control strategy in some cases, a cascaded control strategy is proposed for enhancing the controllability and stabiulity of 4-wheel drive vehicles. The basic idea of the control strategy is that when the effects of inter-axle driving force distribution control can not meet the requirements or when the control has reached certain limit, the direct yaw moment control is activated The results of simulation show that compared with inter-axle driving force distribution control strategy, the cascaded control strategy has more powerful control capability with marked effects.
