  • Patent number: 8903583
    Abstract: The occurrence of shock and the occurrence of the feeling of losing speed can be prevented. When the clutch is engaged from the state in which the clutch is disengaged and a vehicle is being driven by only the power of an electric motor, an electric motor control unit controls the electric motor so that the torque of the electric motor is decreased at a rate determined according to the torque requested by the driver. During the period in which the torque of the electric motor is decreased at the above rate, a clutch control unit controls the engagement of the clutch so that the clutch is engaged after being set to a half-engaged clutch state in which part of the power is transmitted. The present invention is applicable to hybrid vehicles.
