Abstract
Abstract An apparatus for operating the roof panel (1) of a sliding roof or a sliding/tilting roof comprises a motor (2) for moving the roof panel, a control unit (8) for energizing the motor and a setting means (11) for setting a desired position of the roof panel. At putting the apparatus into operation the control unit (8) energizes the motor (2) for moving the roof panel (1) to a (each) extreme open position. A corresponding end position of the roof panel is stored in a memory (12). During operation the control unit restricts the movement of the roof panel as controlled by the setting means (11) by means of the end position(s) stored in the memory.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
Apparatus for operating the roof panel of a vehicle, the apparatus comprising: a motor connected to the roof panel for moving the panel between a closed position and an open position, a control unit for energizing the motor and a setting means connected to the control unit for setting a desired position of the roof panel, said setting means having a predetermined setting range, wherein when the apparatus is put into operation the control unit energizes the motor to move the roof panel to an extreme open first position and an extreme open second position, wherein means are provided for storing corresponding extreme open positions of the roof panel in a memory, wherein the control unit restricts during operation the movement of the roof panel as controlled by the setting means by means of the positions stored in the memory, said control unit including means to adapt the setting range of the setting means to the distance of movement of the roof panel between the closed position and the extreme open first position and also between the closed position and the extreme open second position.
Claim 2
Dependent Claim
185 words
Apparatus for operating the roof panel of a vehicle, the apparatus comprising: a motor connected to the roof panel for moving the panel between a closed position and an open position, a control unit for energizing the motor and a setting means connected to the control unit for setting a desired position of the roof panel, said setting means having a predetermined setting range, wherein when the apparatus is put into operation the control unit energizes the motor to move the roof panel to an extreme open first position and an extreme open second position, wherein means are provided for storing corresponding extreme open positions of the roof panel in a memory, wherein the control unit restricts during operation the movement of the roof panel as controlled by the setting means by means of the positions stored in the memory, said control unit including means to adapt the setting range of the setting means to the distance of movement of the roof panel between the closed position and the extreme open first position and also between the closed position and the extreme open second position.
Claim 3
Dependent Claim
37 words
Apparatus according to claim 1, further comprising a sensor for measuring the speed of movement of the roof panel, wherein the control unit detects the reaching of the extreme open positions by means of the speed sensor.
Claim 4
Dependent Claim
56 words
Apparatus according to claim 2, further comprising a sensor for detecting the closed position of the roof panel, wherein the control unit after moving the roof panel from the extreme open positions into the closed position, determines the position of the roof panel in the extreme open positions, respectively, from the signal of the speed sensor.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 2, wherein the control unit de-energizes the motor if the speed of movement falls below a predetermined minimum speed.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 4, wherein the control unit energizes the motor in a reversed direction of rotation during a short period after said de-energizing of the motor.
Claim 7
Dependent Claim
29 words
Apparatus according to claim 4, wherein after said de-energizing, the control unit energizes the motor in reversed direction of rotation until the roof panel is in point of departure.
Claim 8
Dependent Claim
24 words
Apparatus according to claim 2, wherein the control unit deenergizes the motor if a deceleration of the roof panel exceeds a predetermined maximum value.
Claim 9
Dependent Claim
84 words
Apparatus according to claim 7, wherein during an energizing period of the motor for moving the roof panel into the closed position, the control unit deenergizes the motor if a deceleration of the roof panel exceeds a predetermined maximum value for positions of the roof panel equal to or greater than a predetermined distance from the closed position, the control unit maintaining the energizing until the roof panel arrives in the closed position for positions of the roof panel less than the predetermined distance.
Claim 10
Dependent Claim
33 words
Apparatus according to claim 1, wherein after putting the apparatus into operation, the control unit only energizes the motor for moving the roof panel into the extreme positions after operating the setting means.
Claim 11
Dependent Claim
29 words
Apparatus according to claim 1, wherein the extreme open first position is an extreme open tilting position and the extreme open second position is an extreme open sliding position.
