Abstract

In a method for activating a motor vehicle closure and in a closure device for motor vehicles a sensor device is activated by switching on an activation device and comprises a proximity sensor arranged in the vicinity of the closure part. The activated sensor device transmits an opening signal to the drive device to open the closure part when an approaching person and/or an approaching object comes within a predetermined distance from the proximity sensor, whereupon the drive device opens the motor vehicle closure.

Claims

1. Method for activating a motor vehicle closure comprising a closure part which can be moved by a drive device and with which an orifice of a fuel filler neck can be closed, and a sensor device which is activated by switching on an activation device and comprises a proximity sensor arranged in a vicinity of the closure part, the method comprising:

transmitting an opening signal from the activated sensor device to the drive device to open the closure part when an approaching person or any approaching object comes within a predetermined distance from the proximity sensor, and

transmitting a closing signal from the activated sensor device to the drive device to close the closure part when the person and any object after approaching within the predetermined distance then move away from the proximity sensor beyond the predetermined distance.

2. Method according to claim 1, wherein the vehicle includes an interior, and the method further includes switching on the activation device by manual operation of an activation member arranged in a vehicle interior.

3. Method according to claim 1, further including automatically deactivating the activated sensor device once a predetermined activation period has elapsed if the proximity sensor does not detect the approaching person or object.

4. Method according to claim 3, further including deactivating the activated sensor device after 15 seconds to 40 seconds if the proximity sensor does not detect the approaching person or object.

5. Method for operating a motor vehicle closure part structured to be moved by an automatic drive device to automatically open and close an orifice of a fuel filler neck, the method comprising:

activating a proximity sensor in a vicinity of the closure part by switching on an activation device,

transmitting an opening signal from the activated sensor device to the automatic drive device to automatically open the closure part when the proximity sensor detects a passive object closer than a predetermined distance in proximity to the proximity sensor, and

transmitting a closing signal from the activated sensor device to the drive device to automatically close the closure part when the proximity sensor detects that the previously detected passive object moves beyond a predetermined distance out of proximity to the proximity sensor.

6. Method according to claim 5, wherein activating comprises switching on the activation device by manual operation of an activation member.

7. Method of claim 5 further including transmitting the closing signal from the activated sensor device to the drive device to automatically close the closure part when the proximity sensor fails to detect a passive object closer than a predetermined distance in proximity to the proximity sensor for a predetermined time period after activating the proximity sensor.

8. Method of claim 5 wherein transmitting of the opening signal comprises transmitting the opening signal when the proximity sensor detects that a passive object has moved closer than a predetermined distance in proximity to the proximity sensor.
