Opening and closing device for a vehicle door
First Claim
1. A vehicle body of a vehicle comprising:
- an opening which permits access into and out of the vehicle;
a vehicle door movably supported by the vehicle body for opening and closing the opening;
a hook mechanism which holds the vehicle door relative to the vehicle body under a door opened condition;
a moving mechanism which moves the vehicle door relative to the vehicle body;
an electric releasing actuator operatively connected to the hook mechanism to operate the hook mechanism and effect unhooking of the hook mechanism to permit the vehicle door to be moved in a closing direction to close the opening;
an electric driving device operatively connected to the moving mechanism to operate the moving mechanism and move the vehicle door in the closing direction relative to the vehicle body to close the opening;
operation means for generating a signal indicating that the vehicle door is to be moved in the closing direction to close the opening;
control means for controlling operation of the electric releasing actuator based on the signal from the operation means and controlling operation of the electric driving device to initiate driving of the moving mechanism after initiating operation of the electric releasing actuator.

Abstract
A vehicle is provided with an opening and closing device for opening and closing the vehicle door. A hook mechanism holds the door in an open condition, an electric releasing actuator is operatively connected to the hook mechanism to unhook the hook mechanism for permitting the door to be moved in the closing direction, an electric driving device is adapted to move the door in the closing direction, and an operation means generates a signal for directing that the door be moved in the closing direction. In addition, a control device controls the operation of the electric releasing actuator based upon the signal from the operation means, and controls the electric driving device to initiate driving operation of the electric driving device after initiation of the operation of the electric releasing actuator.

7. A method for closing an opening defined in a vehicle body of a vehicle through movement of a vehicle door relative to the vehicle body comprising:
-
operating an electric release motor operatively connected to a hook mechanism holding the vehicle door at an open condition to unhook the hook mechanism, the driving of the electric release motor being initiated based upon operation of a switch;
counting lapsed time from initiation of the operation of the electric release motor;
judging whether the lapsed time from the initiation of the operation of the electric release motor is at least equal to a first predetermined time; and
initiating driving of an electric driving mechanism for moving the vehicle door in a closing direction relative to the vehicle body based on whether the lapsed time from the initiation of operation of the electric release motor is at least equal to the first predetermined time. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for closing an opening defined in a vehicle body of a vehicle through movement of a vehicle door relative to the vehicle body comprising:
-
directing a door closing operation of the vehicle door that is in an open condition;
releasing a hook mechanism holding the door at the open condition by operation of a first motor operatively connected to the hook mechanism;
counting lapsed time from initiation of operation of the first motor; and
operating a second motor to move the vehicle door relative to the vehicle body in a closing direction based upon the lapsed time from the initiation of operation of the first motor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
