Abstract:
1. A clutch control device for exercising disengagement and engagement control of a clutch in a hybrid vehicle, the hybrid vehicle having formed therein a driving force transmission path for transmitting a driving force from an engine to driving wheels via the clutch, and a rotating force transmission path in which an electric motor is connected between the clutch and the driving wheels to transmit a rotating force of the electric motor to the driving wheels, wherein the clutch comprises a first clutch plate to which the driving force from the engine is inputted, and a second clutch plate engaging the first clutch plate to form the driving force transmission path, the second clutch plate is configured to be synchronized with rotation of the electric motor, and the clutch control device has determination means which determines that engagement of the clutch has been accomplished, on condition that a difference between rotational numbers of the first clutch plate and the second clutch plate at a predetermined engaging time after start of the engagement of the clutch is equal to or smaller than a predetermined value, when the clutch control device performs the disengagement and engagement control of the clutch so as to switch from a first travel mode, in which the vehicle runs by use of the rotating force transmission path alone, to a second travel mode using the driving force transmission path.
