    摘要： There is provided a fuel cell system that generates an electric power by supplying an anode gas and a cathode gas to a fuel cell. The fuel cell system includes: auxiliary machines and a drive motor driven by the generated electric power of the fuel cell; a pressure control unit configured to control a pressure of the cathode gas to be supplied to the fuel cell at a normal target pressure, the normal target pressure being used for ensuring an oxygen partial pressure within the fuel cell in accordance with the generated electric power of the fuel cell; and a warming-up pressure control unit configured to control the pressure of the cathode gas to be supplied to the fuel cell to become a predetermined warm-up acceleration target pressure during warm-up of the fuel cell, the predetermined warm-up acceleration target pressure being higher than the normal target pressure. In a case where there is a request to drive the drive motor during the warm-up of the fuel cell, the warming-up pressure control unit controls the pressure of the cathode gas to be supplied to the fuel cell to a warm-up target pressure between the normal target pressure and the warm-up acceleration target pressure.

    摘要： Disclosed is a control device (40) for an anode non-circulation type fuel cell system including a fuel cell (1), a volume part (12) capable of temporarily storing an anode off-gas discharged from the fuel cell, a discharging device (14) for discharging the anode off-gas to an outside, and a temperature detector (43) for detecting a temperature of the fuel cell. The control device (40) includes an anode gas supply control unit (55) which controls the supply of an anode gas to the fuel cell. The anode gas supply control unit (55) includes an anode upper/lower limit pressure setting unit (61) which sets an anode upper limit pressure and an anode lower limit pressure, an anode pressure increase rate setting unit (62) which sets an anode pressure increase rate based on at least the temperature of the fuel cell detected by the temperature detector, and an anode gas pressure increase/decrease control unit (63) which repeats pressure increase and pressure decrease, the pressure increase being conducted by supplying the anode gas to the anode upper limit pressure at the anode pressure increase rate, the pressure decrease being conducted by restricting the supply of the anode gas to the anode lower limit pressure. When the temperature of the fuel cell detected by the temperature detector is lower than a predetermined temperature, the anode pressure increase rate setting unit (62) sets the anode pressure increase rate at a slower rate than when the temperature of the fuel cell is equal to or higher than the predetermined temperature.

    摘要： A control method for controlling a series hybrid vehicle in which a drive motor and an internal combustion engine are supported in a vehicle body via a plurality of mount members in an integrated state, the method being one in which a controller: causes an electric power generation motor to generate electric power, the electric power generation motor being driven by motive power of the internal combustion engine; actuates the drive motor by using the generated electric power and drives drive wheels; and causes the drive motor to generate regenerative torque that corresponds to a deceleration request during deceleration, wherein the upper limit of the regenerative torque is restricted to a magnitude at which the engine rotational speed of the internal combustion engine during generation of electric power is higher than a floor vibration generation region established based on of the upper limit of the regenerative torque, said region being an engine rotational speed region in which resonance of a vehicle body floor is produced, such that the regenerative torque is generated by the drive motor.

    摘要： Provided is a method for controlling a vehicle comprising an engine, a power generator, and a drive motor, and also comprising a GPF system that drives the power generator via the engine to generate power and drives the drive motor via the power generated by the power generator, and that collects particulate matter in the exhaust of the engine. Said method includes driving the engine via the power generator while performing combustion in the engine to perform retarding discharge, which is a power consumption operation that generates negative ENG torque in the engine, when there has been a discharge request while cutting off fuel to the engine is prohibited.
