This paper describes the real time simulation environment in order to develop and verify the power control algorithm for a hybrid fuel cell vehicle. All power systems involving VCU(vehicle control unit) are applied as a real hardware. On the other hand, the driver model and the longitudinal vehicle dynamics model are applied as a software. The driving load of vehicle obtained from the longitudinal dynamics is implemented by dynamometer. For carrying out Hardware-in-the-loop simulation test, the standard driving cycle applies FUDS(Federal Urban Driving Schedule) cycle and the power control algorithm of fuel cell system applies thermostat type and power follower type. From that, the fuel economy of both 10kw fuel cell and 25kw fuel cell is compared.
