Abstract:
A hybrid vehicle includes a connecting/disconnecting clutch disposed between an engine and an electric motor, an automatic transmission including an input clutch, a starting clutch disposed between the electric motor and the automatic transmission, and a control apparatus for executing an engine-start control operation for starting the engine, by igniting the engine after increasing a rotational speed of the engine by a torque of the electric motor while placing the connecting/disconnecting clutch into an engaged state. In process of the engine-start control operation that is executed when the hybrid vehicle is in a stopped state with the starting clutch being in a released state, the control apparatus places the input clutch in an engaged state until the rotational speed of the engine exceeds a predetermined speed value, and switches the input clutch to a released state after the rotational speed of the engine has exceeded the predetermined speed value.
