摘　　要：为了实现对履带车辆制动能量的回收利用,针对某型履带车辆建立其液压储能式制动系统,分析系统工作模式;在AMESim下建立液压储能式制动系统及车辆模型,在Matlab/Simulink下建立控制系统模型;提出基于踏板行程逻辑门限值的模糊控制策略;在驾驶员不同的制动意图和系统负荷能力条件下,对履带车辆的制动工况进行联合仿真研究。结果表明,在该控制策略下液压储能式制动系统实现了对履带车辆的稳定制动和对制动能量的有效回收。In order to achieve the tracked vehicle braking energy recovery and utilization, a certain type of tracked vehicle hydraulic energy storage braking system was established, and the working mode was analyzod. The model of hydraulic energy storage braking system and the vehicle was established in AMESim, and the control system model was established in Matlab/Simulink. Fuzzy logic control strategy based on pedal opening threshold was proposed. Under the driver＇s different braking intention and conditions of system load capacity, the tracked vehicle＇s braking process was researched under co-simulation. The results show that with the control strategy in the hydraulic energy storage braking system, the stable braking of tracked vehicle and the effective recovery of braking energy were achieved.
