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.

Key words: vehicle engineering, regenerative braking, simulation, hydraulic hybrid vehicle（HHV）
