1. A double clutch system for a hybrid electric vehicle including a connecting shaft that is continuously connected to a motor/generator and is selectively connected to an engine and transmitting torque transmitted to the connecting shaft selectively to two input shafts, the double clutch system comprising:
a double clutch unit including:
a double clutch actuator; andfirst and second clutches selectively connecting the connecting shaft to the two input shafts by control of the double clutch actuator,wherein the first clutch connects the connecting shaft to a first input shaft of the two input shafts and the second clutch does not connect the connecting shaft to a second input shaft of the two input shafts when the double clutch actuator does not operate, andwherein the first clutch does not connect the connecting shaft to the first input shaft and the second clutch connects the connecting shaft to the second input shaft when the double clutch actuator operates; and an engine clutch unit selectively connecting the engine to the connecting shaft.
