摘　　要：为了回收车辆在城市工况运行时的制动能量,降低工程车辆能源消耗和对环境的污染,提高车辆的综合性能,采用并联式液压制动能量回收技术,进行参数匹配计算,提出定比例复合制动力分配控制策略.利用AMESim软件对车辆的能量回收与释放过程进行建模与仿真,并对能量回收过程中二次元件的排量变化进行仿真分析.结果表明:在需求制动强度较低时,该控制策略能够有效地对车辆进行制动和能量回收,达到节能的效果,同时二次元件排量的变化对制动时间有较大影响;在保证制动安全的前提下,最大化的利用能量回收系统提供的制动力是提高能量回收率的最有效方法.In order to recycle braking energy in urban operation, reduce energy consumption and environment pollution, and improve comprehensive performance of vehicle, the parallel hydraulic brake energy recovery technology was used to match parameters calculating and propose a control strategy of fixed proportion of composite brake force distribution. The mathematical model of vehicle energy recovery and release process was established and simulated by AMESim, and the simulation analysis was conducted according to the secondary element displacement changes in the energy recovery process. The results show that when the brake strength demand is low, the vehicle braking and energy recovery control strategy is effective for saving energy. The secondary element displacement change has significant effect on the vehicle braking time. In the premise of safe braking, maximizing the use of braking energy recovery system is the most effective way to improve the energy recovery.
