| 摘 要： | 分析了并联式液压混合动力车辆制动过程的能量损耗,确定了液压混合动力系统节能研究的重要方向。通过对比计算和仿真研究,分析了驱动方式、运行工况、扭矩耦合器传动比等因素对并联式液压混合动力车辆制动性能的影响。结果表明,采用前轴驱动方式,适当增大扭矩耦合器传动比,合理地选择液压蓄能器容积和工作压力有利于提高车辆在城市运行工况下的再生制动性能。

| Abstract: | The energy losses in the parallel hydraulic hybrid vehicle(PHHV) during braking were analyzed and the magor directions of the energy-saving research for the hydraulic hybrid power system were derived.The effects of the driving mode,the driving cycle,the transmission ratio of torque coupler on the regenerative braking behavior of PHHV were studied by contrast calculation and simulation.The results showed that adopting the front wheel driving mode,increasing appropriately the transmission ratio of torque coupler and selecting reasonably the volume and working pressure of hydraulic accumulator are helpful to improve the regenerative braking performance of PHHV,especially under urban driving cycles. |
