    Abstract: A fuel cell plug-in hybrid vehicle includes a fuel cell having an anode side and a cathode side with a compressor connected to the cathode side. An electric motor is drive-connected exclusively to the compressor. A converter is connected electrically on one side to the motor and on the other side to a high-voltage battery. A controller switches the vehicle between two different operating states. In a first operating state, the high-voltage battery supplies electrical power to the motor via the converter so that the electric motor drives the compressor. In a second operating state, an electrical voltage is supplied from a power supply system to the motor or to the converter via a power supply line. The motor can modify the amplitude of the system voltage with the modified voltage present across the converter, which converts the voltage into a DC voltage applied across the high-voltage battery.

The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated by the motor-generator when the coupling is engaged.

    Abstract: When a braking request is made while a SOC recovery switch is turned off, regeneration driving of a rear wheel motor is prohibited. In this case, a front wheel motor, the rear wheel motor, and an oil hydraulic brake device are controlled such that requested braking torque is exerted on a vehicle with regenerative driving of the front wheel motor and without regenerative driving of the rear wheel motor. When the braking request is made while the SOC recovery switch is turned on, the regeneration driving of the rear wheel motor is permitted. In this case, the front wheel motor, the rear wheel motor, and the oil hydraulic brake device are controlled such that the requested braking torque is exerted on the vehicle with regenerative driving of the front wheel motor and the rear wheel motor.
