Abstract: The low efficiency power generation part of a control device is provided with an operating point setting part setting a target current and a target voltage defining an operating point of the fuel cell at the time of low efficiency power generation and a generated electric power control part making the generated electric power of the fuel cell increase and decrease at the time of low efficiency power generation by controlling the current of the fuel cell to the target current while making the flow rate of feed of oxidizing agent gas supplied to the fuel cell fluctuate so that the voltage of the fuel cell increases and decreases above and below the target voltage within a range where the charged and discharged electric powers of the rechargeable battery do not become larger than the allowable charged and discharged electric powers.

Abstract: A hybrid vehicle includes an electric generator, a drive motor, a power storage device, a power consuming device, and a controller. The controller is configured to control driving of the power consuming device. The controller is configured to execute power consumption increasing control when a vehicle power balance value is larger than a first threshold while the drive motor operates in a braking-period power generation mode.

Abstract: A driving force control device includes a controller. The controller is configured to increase driving force of a vehicle in accordance with a driver's operation to request acceleration. The controller is configured to restrict subsequent increase of the actual driving force when it determines that increase of actual driving force of the vehicle stagnates, relative to required driving force determined according to at least the driver's operation to request acceleration. The controller is configured to restrict the increase of the actual driving force so that a rate of increase of the actual driving force is reduced as a stagnation period for which the increase of the actual driving force stagnates is longer.
