A control device for an electric vehicle equipped with a drive motor and a fuel cell includes a control output setter, a motor controller, and a fuel cell controller. The control output setter is configured to set a target value of an output of the drive motor based on a request command value. The motor controller is configured to control an output of the drive motor based on the target value using an electric power from a secondary battery as a power source. The fuel cell controller is configured to control the supply of a generated power by activating the fuel cell when the remaining capacity of the secondary battery decreases or an output of the secondary battery is insufficient. The control output setter decreases an allowable maximum value of the output of the drive motor when the remaining capacity can be decreased even after the fuel cell is activated.

A method and system for controlling a fuel cell vehicle are provided. The method includes determining, by a controller, a driving pattern of a driver based on driving information including acceleration and deceleration information. A condition for activation of an idling-stop of a fuel cell is then set based on the determined driving pattern and the fuel cell is stopped from generating electric energy when the condition for activation of the idling-stop is satisfied.

When a calibration starting condition of a pressure sensor is satisfied while a fuel cell vehicle is traveling, the fuel cell vehicle starts to travel by using electric power supplied from a secondary battery. In the fuel cell vehicle, a pressure sensor is calibrated based on hydrogen pressure in a hydrogen gas flow channel downstream of a pressure reducing valve after a shut-off valve of a hydrogen tank is closed, and the hydrogen in a hydrogen gas flow channel is exhausted until hydrogen pressure upstream of the pressure reducing valve and hydrogen pressure downstream of the pressure reducing valve become substantially equal to each other. The fuel cell vehicle travels by using electric power supplied from the secondary battery while the pressure sensor is being calibrated, so that calibration processing of the pressure sensor can be performed without causing a noise.

A control device is configured to, in a case that an internal combustion engine is made to start up before travel start of a vehicle in a parked state, when an auxiliary battery has at least a predetermined value of battery voltage, make the internal combustion engine start up after executing fuel heating processing for heating fuel by glow plugs to which electric power is transmitted, or when the battery voltage of the auxiliary battery is less than the predetermined value, execute the fuel heating processing after executing charge processing for charging the auxiliary battery using a main battery and then start up the internal combustion engine.
