Study on Hybrid Vehicle Using Constant Pressure Hydraulic System with Flywheel for Energy Storage 2004-01-3064

In this study, we evaluate the effectiveness of the hybrid system using Constant Pressure Hydraulic System (CPS). In the city traffic, vehicles are required to start and stop frequently. Therefore, the engine often runs in its low efficiency area. So, we study the CPS hybrid vehicle. This paper shows the experimental and simulation results. The efficiency of this system depends on the performance of the hydraulic pump/motor. We investigate various methods to keep the operation of the pump/motor at the high performance point and compared the fuel economy with that of conventional vehicle.
