Considering the high power density and high recovery efficiency of the hydraulic energy storage system, the power system combined with the hydraulic pump is adopted. The matching of automobile power transmission system includes the matching of hydraulic pump parameters, hydraulic accumulator parameters, motor parameters and battery parameters. AMESim and Simulink were used to carry out simulation modeling to analyze its performance. The simulation results showed that the adaptive combination of hydraulic system and battery system in electro-hydraulic hybrid vehicle could effectively improve the economic performance of the vehicle while ensuring the dynamic performance of the vehicle. It puts forward more efficient technology concept for the future development of hybrid electric vehicle.
