Abstract

A device for motorically and manually adjusting a second vehicle part relative to a first vehicle part in an adjustment range is provided. The device comprising at least a driving device by means of which the second vehicle part is motorically adjustable in at least one adjustment direction and can be held in an adjustment position within the adjustment range relative to the first vehicle part, wherein the driving device is switchable between a holding position and a release position and in the holding position the second vehicle part is held in an adjustment position via the driving device and in the release position is manually adjustable within the adjustment range, and an electronic control device by means of which the driving device is switchable between the holding position and the release position in response to an operating event triggered by a user.

First claim

The invention claimed is:

1. A device for motorically and manually adjusting a second vehicle part relative to a first vehicle part in an adjustment range, the device comprising:
a driving device configured to motorically adjust the second vehicle part in both a closing direction and an opposite opening direction and configured to hold the second vehicle part in an adjustment position within the adjustment range between a maximally open and fully closed position relative to the first vehicle part, wherein the driving device is switchable between a holding position and a release position such that in the holding position the second vehicle part is held in an adjustment position via the driving device and in the release position the second vehicle part is manually adjustable within the adjustment range, and
an electronic control device configured to switch the driving device from the holding position into the release position in response to an operating event triggered by a user in order to permit a manual adjustment of the second vehicle part by the user relative to the first vehicle part,
wherein the electronic control device is coupled with at least one sensor unit configured to electronically detect the operating event triggered by the user, via the operating event, the user signals the manual adjustment of the second vehicle part in the closing or the opposite opening direction, and
wherein the electronic control device is further configured to, in response to the operating event triggered by the user and before switching into the release position for enabling the manual adjustment of the second vehicle part, initially actuate the driving device for a power-operated adjustment out of the adjustment position in either the closing or opposite opening direction depending on which one of the closing and opposite opening directions the manual adjustment is to be made, thereby creating a transitional adjusting movement of the second vehicle part which is configured to transition into an entirely manual adjustment of the second vehicle part.

2. The device according to claim 1 , wherein the at least one sensor unit is configured to detect a force manually applied onto the second vehicle part, via which the second vehicle part is pushed or pulled by the user from the adjustment position in the closing or opposite opening direction.

3. The device according to claim 1 , wherein the electronic control device is configured to initially actuate the driving device for the power-operated adjustment for a period of less than 2 seconds in response to an operating event triggered by the user before switching into the release position.

4. The device according to claim 3 , wherein the electronic control device is configured to initially actuate the driving device for a period of less than one second.

5. The device according to claim 4 , wherein the electronic control device is configured to initially actuate the driving device for a period in a range of 40 ms to 650 ms or 50 ms to 300 ms.

6. The device according to claim 1 , wherein at least one desired profile curve is stored in the electronic control device for the driving device, by which the course of an adjustment speed of the second vehicle part is specified during the power-operated adjustment before switching into the release position.

7. The device according to claim 6 , wherein the at least one desired profile curve extends in a ramp-like manner in at least one portion.

8. The device according to claim 6 , wherein the electronic control device is configured to actuate the driving device to motorically adjust the second vehicle part out of the adjustment position with different adjustment speeds, namely depending on a detected vehicle inclination, the adjustment direction, the adjustment position within the adjustment range, and/or in dependence on an actuating force with which the user acts on the second vehicle part, in order to trigger the operating event, and different desired profile curves for the driving device that are stored in the electronic control device to specify different profiles of the adjustment speed depending on the vehicle inclination, the adjustment direction, the adjustment position and/or a height of the actuating force.

9. The device according to claim 1 , wherein the electronic control device is configured to actuate the driving device to motorically adjust the second vehicle part out of the adjustment position with different adjustment speeds, namely in dependence on a detected vehicle inclination, in dependence on the adjustment direction, in dependence on the adjustment position within the adjustment range, and/or in dependence on an actuating force with which the user acts on the second vehicle part in order to trigger the operating event.

10. The device according to claim 1 , wherein the driving device includes a switchable transmission unit and/or a switchable coupling unit via which:
a drive motor of the driving device is coupled with a drive element in the holding position, the drive element being configured to transmit a motoric adjusting force for the power-operated adjustment of the second vehicle part, and
a coupling between the drive motor and the drive element is interrupted in the release position.

11. A method for motorically and manually adjusting a second vehicle part relative to a first vehicle part in an adjustment range, the method comprising:
motorically adjusting the second vehicle part in both a closing direction and an opposite opening direction by a switchable driving device and holding the second vehicle part in an adjustment position within the adjustment range between a maximally open and a fully closed position relative to the first vehicle part,
holding the second vehicle part in an adjustment position via the drive device being in a holding position;
electronically detecting, by at least one sensor unit, an operating event triggered by a user, via which the user signals a manual adjustment of the second vehicle part in the closing or opposite opening direction,
in response to the operating event triggered by the user and before switching into a release position for enabling the manual adjustment of the second vehicle part, initially and motorically adjusting the second vehicle part via the driving device from the adjustment position in either the closing or opposite opening direction depending on which one of the closing and opposite opening directions the manual adjustment is to be made thereby creating a transitional adjusting movement of the second vehicle part which is configured to transition into an entirely manual adjustment of the second vehicle part, and
then switching the driving device from the holding position into the release position in which the second vehicle part is manually adjustable within the adjustment range in order to permit the entirely manual adjustment of the second vehicle part by the user relative to the first vehicle part.

12. A device for motorically and manually adjusting a second vehicle part relative to a first vehicle part in an adjustment range, the device comprising:
a driving device configured to motorically adjust the second vehicle part in an adjustment direction and configured to hold the second vehicle part in an adjustment position within the adjustment range relative to the first vehicle part, wherein the driving device is switchable between a holding position and a release position such that in the holding position the second vehicle part is held in an adjustment position via the driving device and in the release position the second vehicle part is manually adjustable within the adjustment range, and
an electronic control device configured
