Beschreibung
Zusammenfassung:	A hybrid vehicle includes an electric motor with a rotatable rotor. A centrifugally-actuated clutch has a first rotatable member, a second rotatable member, and at least one actuator member attached to the first rotatable member. One of the first rotatable member and the second rotatable member is operatively connected to the wheels. The other of the first rotatable member and the second rotatable member is operatively connected to the rotor. The actuator member is configured to transfer torque between the first rotatable member and the second rotatable member by an amount that decreases due to centrifugal force acting on the actuator member as a rotational speed of the first rotatable member increases. A method of control is also provided.
