摘　　要：设计开发了一种电机式电控限滑差速器,探讨了其结构组成与工作过程,同时基于整车四轮动力学模型,仿真分析了电控限滑差速器对后驱动车辆动力性的影响。结果表明,装有电控限滑差速器的后驱动车辆,在对分路面上的原地起步加速时间和直接档加速时间显著缩短,在对分坡道路面上的最大爬坡度显著提高,其动力性有明显改善。An electromotor-type electronically limited-slip differential(ELSD) was developed and its structural composition and working principle were presented.The influence of the ELSD on the dynamic performance of a rear-wheel drive vehicle on the split-μroad was simulated by a four-wheel vehicle dynamic model.The simulated results show that the ELSD decreases the accelerating time from the start and the accelerating time on the direct gear on the split-μroad and increases the maximal gradeability on the split-μslo...
