ABSTRACT:
The present invention intends to provide a control device for a fuel cell vehicle which suppresses the deterioration of driveability upon acceleration without increasing the size of a driving electric motor or a motor driver. When a requested output (PD_CAL) exceeds a first output limit determined depending on a continuous output rating of an electric motor10or a motor driver5and an increasing rate of the requested output (PD_CAL) exceeds a reference increasing rate, an upper-limit target output determining unit52determines an assist time used as a time during which the electric motor10can be operated continuously by the requested output (PD_CAL) on the basis of the requested output (PD_CAL) and an open-circuit voltage (Vbat_o) of a battery3. Until the assist time is elapsed, the upper-limit target output (PD_LMT) is set to a second output limit (>the first output limit) determined depending on a short-time output rating of the electric motor10or the motor driver5.
