Patent ID: 8097369

Claim:
A control apparatus for a fuel cell vehicle comprising: a motor which drives a vehicle; a motor control device which controls driving and regenerative operations of the motor; a fuel cell which serves as a fuel cell system constituting a power source for the motor, which generates power by an electrochemical reaction using reaction gas supplied from a reaction gas supply device; an accumulator which is charged by a power generation of the fuel cell and a regenerative power from the motor; an output control device which controls an output of the fuel cell; a voltage reduction degree prediction device suitably programmed with instructions which, when executed by the voltage reduction degree prediction device, cause the voltage reduction degree prediction device to predict a reduction degree of system voltage according to an operational state of the motor; a motor output restriction device suitably programmed with instructions which, when executed by the motor output restriction device, cause the motor output restriction device to restrict a motor output according to the reduction degree of the system voltage predicted by the voltage reduction degree prediction device; and a tachometer which detects a number of rotations of the motor, wherein the voltage reduction degree prediction device is programmed with instructions which, when executed by the voltage reduction degree prediction device, cause the voltage reduction degree prediction device to predict a maximum value of an amount of change in a motor output based on the number of rotations detected by the tachometer.
