| Abstract: | The hydraulic system of electronic-continuously variable transmission (e-CVT) of full hybrid electric vehicle was designed. Hydraulic scheme was confirmed based on the structure and driving modes of the hybrid system. Oil pump was driven by output shaft or electric motor in order to match the flow requirement of different driving situation. The structure dimension of hydraulic valves was designed by theoretical calculation. The dynamic model of hydraulic system was established by ITI-SimulationX to investigate the characteristics of oil flow and pressure. Simulation results indicated the hydraulic system could satisfy the design flow and pressure requirement. |
