摘　　要：建立了液驱混合动力车辆制动能量回收的数学模型,对制动能量回收过程中的能量损耗、能量回收和制动性能进行仿真计算和分析,并对制动初始压力和蓄能器容积等主要设计参数对制动能量回收效率以及车辆制动性能的影响进行了定量分析,为液驱混合动力车辆液压系统进一步的优化设计和控制打下了良好的基础.The mathematical models of braking energy recycling are established for hydraulically-driven hybrid-powered vehicles. In this process, the energy loss-recycling and braking performance are speculated based on simulation analysis. Accordingly, such design specifications as initial braking pressure and energy-storage volume are quantitatively analyzed for energy recycling efficiency and barking performance. Therefore, this approach paves a new venue for the optimized design and control on relevant hydraulic systems.
