Patent ID: 7996124

Claim:
A method for controlling a fuel cell vehicle, the method comprising: generating a torque (T ACCEL ) calculated based on an accelerator pedal depression value upon completion of start-up of a fuel cell and entering a fuel cell only mode; performing a torque limit control for the torque (T ACCEL ) calculated based on the accelerator pedal depression value; performing charging from the fuel cell to a power storage means while the vehicle moves slowly by the torque limit control under the fuel cell only mode; and directly connecting the fuel cell to the power storage means by a main relay to enter a hybrid mode, when a voltage difference between the fuel cell and the power storage means is within a predetermined range, wherein the charging of the power storage means is performed by a current limit control according to a duty ratio control of an insulated gate bipolar transistor (IGBT) of an initial charging device, connected between the fuel cell and the power storage means, before the fuel cell and the power storage means are directly connected.
