Abstract
Disclosed is a control device for a fuel cell vehicle which prevents that a fuel cell vehicle cannot run immediately after an abnormal condition of a fuel cell occurs. A current supply limiting unit permits output current limiting means to interrupt a current supplied from a fuel cell to a capacitor and a motor driver when an upper limit amount of generated electric energy (Ifc_LMT) outputted from a fuel cell control unit and indicative of an upper limit amount of electric energy generated by the fuel cell is equal to a predetermined amount of generated electric energy or lower. When the upper limit amount of generated electric energy (Ifc_LMT) is equal to the predetermined amount of generated electric energy or lower and an output limit electric energy (PLD) is equal to a target output (PD_REQ) or lower, a necessary regenerative torque calculator calculates necessary regenerative torque (REG_TRQ) so that a reactive gas supply device can be operated by a regenerative electric energy generated in an electric motor A torque command selector outputs the necessary regenerative torque (REG_TRQ) as a torque command (TRQ_CMD) to the motor driver
