Hydraulic Hybrid Vehicle(HHV) is a hybrid vehicle using hydraulic motor/pump and accumulators to save regenerative energy instead of electric motors and Li-ion batteries. This system is known that it has up to 35% fuel saving effect and 90% increased driving distance, but has not been commercialized because of cost uncertainty issue compared to Hybrid electric vehicles(HEVs). Therefore, a HHV powertrain simulation model was developed using a software platform for hydraulic system analysis in this paper, and it used for comparing the fuel saving effect according to driving strategies. And down-scaled bench test model of a HHV powertrain was built up to be run by driving strategies and powersplit control for verifying the fuel saving effect.
