Vehicle door opening and closing apparatus
First Claim
1. A vehicle door opening and closing apparatus comprising:
- an electric driving power source generates a driving force that performs an opening and closing operation of a vehicle door;
an electromagnetic clutch device provided between the vehicle door and the electric driving power source, and selectively performs and interrupts a driving force by the electric driving power source transmitting to the vehicle door, the electromagnetic clutch device comprising;
a rotor;
an electromagnetic coil integrated with the rotor; and
an armature, and a controlling means for controlling the driving power source and the electromagnetic clutch device, wherein, when the controlling means interrupts electric power supplying to the electromagnetic coil, the rotor and the armature are controlled at a disconnected state, in which the driving force transmission is interrupted between the electric driving power source and the vehicle door and a manual opening and closing operation of the vehicle door is allowed, and when the controlling means supplies electric power to the electromagnetic coil, the rotor and the armature are controlled at a connected state, in which the driving force transmission between the electric driving power source and the vehicle door is performed, and wherein, after establishing the connected state, the controlling means interrupts power supply to the electromagnetic coil and activates the electric driving power source.

Abstract
When an ECU interrupts electric power supplying to an electromagnetic coil with a rotor, a rotor and an armature are controlled at a disconnected state, in which a driving force transmission between a vehicle door and a electric driving power source is interrupted and a manual opening and closing operation of the vehicle door is allowed. When the ECU supplies electric power to the electromagnetic coil, the rotor and the armature are controlled at a connected state, in which the driving force transmission between the vehicle door and the electric driving power source is performed. After the ECU activates the electric driving power source to perform one of an opening operation, and a closing operation, of the vehicle door, the ECU interrupts electric power supplying to the electromagnetic coil and activates the electric driving power source.
