| Summary: | 碩士 === 國立成功大學 === 機械工程學系碩博士班 === 101 === Conventional vehicles with internal combustion engine have two defects which causing energy consumption. One is the loss of the braking energy, the other is low operating efficiency of internal combustion engine. The purpose of this article is to solve these two energy consumption problems with series hydraulic hybrid vehicle (SHHV). Series hydraulic hybrid vehicle uses a hydrostatic driving system. With the constant pump, the engine would be forced to operate at high efficient region, and the driving system uses hydraulic accumulator as energy saving device to save braking energy. The experimental platform would be constructed from the two concepts. To be aimed at hydrostatic transmission and construction of real vehicle to improve the circuit step by step. Next, designed controller and control logic to operate series hydraulic hybrid vehicle. As a result, the vehicle would be operated, and the experimental platform would run the dynamic driving test. Finally, series hydraulic hybrid vehicle have been simulated by combining mathematical model with control logic, then the energy saving of the SHHV would be discussed.
