摘　　要：阐述了差速器锁止自动控制系统(VDLS)的工作原理和控制方法。针对多轮越野车辆路况及车况复杂多变的特点,采用模糊控制技术对VDLS进行动态调控,完成了模糊控制器的设计,并以某8×8越野车辆为基础进行了控制性能试验。结果表明,由于VDLS的控制作用,使得越野汽车可实时改变驱动模式,保证驱动轮处于合理的驱动状态,从而使装备VDLS的越野车辆在不良路况下的通过性要明显好于未装备VDLS的越野车辆。Working principle and control method of differential lock automatic control system（VDLS） are presented in the paper.In view of the complicated features of road and vehicle conditions of multi-wheel off-road vehicle,fuzzy control technology is applied in this paper to dynamically regulate and control VDLS,and fuzzy controller is designed.Through control performance test of a 8×8 vehicle,it was proved that the off-road vehicle can real-time change drive mode and keep the driving wheel in a logical driving status with the control of VDLS,which offers better trafficability to the off-road vehicle equipped with VDLS compared with vehicle without VDLS in poor road conditions.
