The studied hydraulic hybrid vehicle was composed of the hydraulic pump,high-pressure accumulator,low-pressure accumulator,switch valve and control system. The mathematical model of the hydraulic hybrid power system and the mathematical model of the displacement servo system of hydraulic pump/motor were built. The control strategy for hydraulic hybrid vehicle was pro-posed. The simulation and experiment to the dynamic characteristics of the hydraulic hybrid vehicle were finished. The experimental re-sults prove that the simulation model is effective and the control strategy is reasonable.
