Abstract

An automatic door operating device drives a door for a pivotal movement in accordance with a switch operation. The automatic door operating device includes a handle disposed on the door; and a controller. The controller allows the door to be manually operable for the pivotal movement when the handle is operated during a time the door is in a process of being driven for the pivotal movement.

Claims

1. An automatic door operating device for driving a door for a pivotable movement in accordance with a switch operation, the automatic door operating device comprising:

a door driving mechanism operable for driving the door;

a handle disposed on the door; and

a controller operative to detect handle operation and disengage the door driving mechanism, whereby the controller allows the door to be manually operable for the pivotal movement when the handle is operated during a time the door is in a process of the pivotal movement.

5. The automatic door operating device as claimed in claim 1, in which

the door is a back door of a motor vehicle; and

the handle is an outside handle disposed outside the back door.

2. An automatic door operating device for driving a door for a pivotal movement in accordance with a switch operation, the automatic door operating device comprising:

a handle disposed on the door; and

a controller for allowing the door to be manually operable for the pivotal movement when the handle is operated during a time the door is in a process of being driven for the pivotal movement,

in which the automatic door operating device further comprises;

a drive gear comprising;

a drive source for driving the door for the pivotal movement, the door and the drive source constituting a transmission system therebetween the transmission system for transmitting a drive force for driving the door for the pivotal movement, and

a clutch intervening in the transmission system;

wherein the controller turns on the drive source and the clutch for the pivotal movement of the door; and

the controller turns off at least the clutch of the drive gear when the handle is operated during the time the door is in the process of being driven for the pivotal movement.

3. The automatic door operating device as claimed in claim 2 further comprising

a switch for stopping the door, in which

the controller takes the following sequential steps:

when the switch is operated during the time the door is in the process of being driven for the pivotal movement, the controller turns off the drive source, leaving the clutch turned on, and

when the handle is operated, the controller turns off the clutch.

4. The automatic door operating device as claimed in claim 3, in which the switch is one of a door switch which is so disposed in a motor vehicle as to output a signal for the pivotal movement of the door, and a keyless switch which outputs, by wireless, the signal for the pivotal movement of the door from a position remote from the motor vehicle.

6. A motor vehicle having a door which is, at an upper end of the door, pivotally connected proximate to a rear end of a roof of the motor vehicle, the motor vehicle comprising:

an automatic door operating device for opening and closing the door in accordance with a switch operation, the automatic door operating device comprising;

a door driving mechanism operable for driving the door;

a handle disposed on the door; and

a controller operable to detect handle operation and disengage the door driving mechanism, whereby the controller allows the door to be manually operable for the pivotal movement when the handle is operated during a time the door is in a process of being driven for the pivotal movement.

7. A motor vehicle having a door which is, at an upper end of the door, pivotally connected to a rear end of a roof of the motor vehicle, the motor vehicle comprising:

an automatic door operating device for opening and closing the door in accordance with a switch operation, the automatic door operating device comprising;

a handle disposed on the door; and

a controller for allowing the door to be manually operable when the handle is operated during a time the door is in a process of being driven for one of an opening operation and a closing operation, in which the door is a back door of the motor vehicle;

the automatic door operating device further comprises;

a drive gear comprising;

an electric motor for opening and closing the door, the door and the electric motor constituting a transmission system therebetween, the transmission system transmitting a drive force for opening and closing the door, and

a clutch intervening in the transmission system;

the controller turns on the electric motor and the clutch for opening and closing the door; and

the controller turns off at least the clutch of the drive gear when the handle disposed on an outer surface of the door is operated during the time the door is in the process of being driven for one of the opening operation and the closing operation.

8. The motor vehicle as claimed in claim 7 further comprising a switch for opening, closing and stopping the door, in which

the switch comprises:

a door switch which is so disposed in the motor vehicle as to output a signal for opening and closing the door, and

a keyless switch which outputs, by wireless, the signal for opening and closing the door from a position remote from the motor vehicle; and

the controller takes the following sequential steps for stopping the door;

when one of the door switch and the keyless switch is operated during the time the door is in the process of being one of the opening operation and the closing operation, the controller turns off the drive source, leaving the clutch turned on, and

when the handle is operated, the controller turns off the clutch.
