Nowadays researches about the Eco-friendly vehicle, hybrid electric vehicle, fuel cell vehicle and electric vehicle are under active proceeding. Since most of the new energy vehicle has a motor, the regenerative braking system can be used to improve the vehicle energy utilization efficiency. The regenerative braking system can transform the kinetic energy to the electric energy through the motor in the regenerative braking. This technology played a significant role in achieving the high energy usage. But there are also some limitations in the vehicle driving safety and efficiency for the regenerative braking system. For example, When the vehicle velocity is very low and the battery SOC is too high, the motor or electric product is limited by the change of temperature or conditions. As a result, the mechanical brake system is used to compensate the lack of brake force when the regenerative braking system is limited. Therefore, when the vehicle changes to the mechanical braking, heavy decelerations will occur, which may give driver a feeling of not safe. In this paper, a fuel cell vehicle simulator installed with EMB is used to simulate the regenerative braking system of Eco-friendly vehicle. Research about combining the regenerative system and mechanical brake system to achieve the vehicle deceleration in an instant time is under developing. Fuel efficiency, safety and driving feeling of the vehicle which has the regenerative braking system are researched to reduce the comfortlessness.

Nowadays, various researches about eco-friendly vehicles such as hybrid electric vehicle, fuel cell vehicle and electric have been actively carried out. Since most of these green cars have electric motors, the regenerative energy technology can be used to improve the fuel economy and the energy of vehicles. The regenerative brake is an energy recovery mechanism which slow a vehicle by converting its kinetic energy into electric energy, which can be either used immediately or stored until needed. This technology plays a significant role in achieving the high energy usage. However, there are some technical problems in driving safety and ride comfort of the vehicles.

Recently vehicle owners are increasingly interested in HEY(Hybrid Electric Vehicle) which offer the advantage of low fuel consumption in traffic-jammed city environment, serving as alternative for ever depleting energy resources. Especially regarding HEV transmission, many researches are done on A/T(Automatic Transmission) which causes less fatigue and stress to drivers due to absence of the necessity to manipulate clutch or transmission lever as frequently though the price is relatively higher than M/T(Manual Transmission). This study verified the real time feasibility by using HEY integrated simulator. In addition, in order to verify the A/T model, the core part of HEV this study composed HILS(Hardware-in-the-loop simulation), and carried out verification of A/T model and research on the performance evaluation by using Bench Tester that directly simulated two-axis parallel HEY model.
