Patent ID: 7177736

Claim:
A control device for a fuel cell vehicle, comprising: motor-requested-output determining means for determining a requested output for a driving electric motor; motor-target-output calculating means for calculating a target output of the electric motor while limiting the target output to a predetermined upper-limit target output or lower depending on the requested output; motor driving means for outputting a driving electric energy depending on the target output to the electric motor; a fuel cell which is used as a power supply for the motor driving means; an electric double layer capacitor which is connected parallel to the fuel cell so as to be charged by the fuel cell and to be discharged for compensation for the insufficient amount of generated electric energy when the amount of electric energy generated by the fuel cell is insufficient; reactive gas supply means for supplying reactive gases at a rate depending on the target output to the fuel cell; capacitor-charging-amount recognizing means for recognizing the amount of electric energy charged into the electric double layer capacitor; and assist time calculating means for calculating an assist time used as a time during which the electric motor can be operated continuously by the requested output on the basis of the requested output and the amount of electric energy charged into the electric double layer capacitor in an abruptly increasing state of the requested output in which the requested output exceeds a first output limit and an increasing rate of the requested output exceeds a predetermined reference increasing rate, the first output limit being determined in accordance with a continuous output rating of the electric motor or the motor driving means, wherein when the requested output is not in the abruptly increasing state, the motor-target-output calculating means sets the first output limit to the upper-limit target output, and when the requested output is in the abruptly increasing state, the motor-target-output calculating means sets a second output limit larger than the first output limit to the upper-limit target output within the assist time, the second output limit being determined in accordance with a short-time output rating of the motor driving means or the electric motor.
