Powered opening and closing system for vehicle's door
First Claim
1. A powered opening and closing system for a vehicle door, comprising:
- a motor;
a drive mechanism for moving the door in opening and closing directions using the motor;
an operation detecting sensor for detecting a handle operation when the door is operated to open/or close;
a control circuit for prohibiting operation of the drive mechanism when a predetermined operation prohibiting condition is detected and;
a vehicle running information unit that detects the predetermined operation prohibiting condition,wherein the drive mechanism comprises a clutch that is configured to connect and disconnect a power transmission path between the motor and the door, the drive mechanism braking movement of the door by putting the clutch in an engaged state while the motor is kept stopped, andwherein, while the predetermined operation prohibiting condition is detected, the control circuit is operable to;
control the clutch to be engaged while keeping the motor stopped when an opening of the door from a fully closed position is detected; and
control the clutch to be disengaged when a door closing operation of the handle is detected by the operation detection sensor,wherein the control circuit controls the clutch to be disengaged only when the operation detecting sensor detects an operation of the handle in a door closing direction.

Abstract
A powered opening and closing system includes a door supported on a vehicle body, a motor, a drive mechanism for moving the door in opening and closing directions by virtue of power of the motor, an operation detecting sensor for detecting a handle operation when the door is operated to open or close, and a control circuit for prohibiting the operation of the drive mechanism when a predetermined operation prohibiting condition is detected. The drive mechanism brakes the movement of the door by putting the clutch in an engaged state while the motor is kept stopped. While the predetermined operation prohibiting condition is detected, the control circuit controls the clutch to be engaged while keeping the motor stopped when an opening of the door is detected, and controls the clutch to be disengaged when an operation of the handle is detected by the operation detection sensor.
