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 motoror a motor driverand an increasing rate of the requested output (PD_CAL) exceeds a reference increasing rate, an upper-limit target output determining unitdetermines an assist time used as a time during which the electric motorcan be operated continuously by the requested output (PD_CAL) on the basis of the requested output (PD_CAL) and an open-circuit voltage (Vcap_o) of a capacitorUntil 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 motoror the motor driver
