Abstract

A control unit for establishing a functional connection between two gearing components comprises at least one control element, which can be moved in order to switch the control unit between different switching states, wherein the at least one control element is configured to provide a retaining force between the gearing components in a first switching state, and to allow movement of the gearing components in relation to one another in a second switching state. An actuator is used to move the at least one control element. A control mechanism controls the actuator. It is provided thereby that the control mechanism is configured to activate the actuator to switch the control unit from the first switching state to the second switching state, in order to move the at least one control element to reduce the retaining force (FH) based on a predetermined delay function (VF).

First claim

What is claimed is:

1 . A control unit for establishing a functional connection between two gearing components, that has
at least one control element, that can be moved in order to switch the control unit between different switching states, wherein the at least one control element is configured to provide a retaining force between the gearing components in a first switching state, and to allow a relative movement of the gearing components in a second switching state, an actuator for moving the at least one control element, and a control mechanism for controlling the actuator, characterized in that the control mechanism is configured to activate the actuator to switch the control unit from the first switching state to the second switching state in order to move the at least one control element to reduce the retaining force (FH) based on a predetermined delay function (VF).

2 . The control unit according to claim 1 , characterized in that the delay function (VF) causes a delay in transitioning the control unit from the first switching state to the second switching state, which is greater than or equal to a predetermined minimum delay.

3 . The control unit according to claim 2 , characterized in that the delay is greater than 1 second, preferably greater than 2 seconds.

4 . The control unit according to claim 1 , characterized in that the control mechanism is configured to activate the actuator to move the at least one control element such that the retaining force during the transition of the control unit from the first switching state to the second switching state changes in a first time interval (T 1 ) by a first amount (A 1 ), and in a subsequent, second time interval (T 2 ) by a second amount (A 2 ), which is greater than the first amount (A 1 ).

5 . The control unit according to claim 4 , characterized in that the control mechanism is configured to activate the actuator to move the at least one control element such that the retaining force during the transition of the control unit from the first switching state to the second switching state changes in a third time interval (T 3 ) following the second time interval (T 2 ) by a third amount (A 3 ), which is less than the second amount (A 2 ).

6 . The control unit according to claim 1 , characterized in that the control mechanism is configured to activate the actuator in response to a command for switching the control unit from the first switching state to the second switching state.

7 . The control unit according to claim 1 , characterized by a brake cover, wherein at least one control element
bears in a fixed manner on the brake cover in a coupling state, bears on the brake cover in a non-braking manner in a freewheel state, and is pressed against the brake cover in a braking manner by the positioning element in a braking state.

8 . The control unit according to claim 7 , characterized in that the first switching state corresponds to the coupling state or the braking state, and the second switching state corresponds to the freewheel state.

9 . The control unit according to claim 8 , characterized by a positioning element for moving the at least one control element and a carrier, in relation to which the brake cover can rotate, and on which the positioning element and the at least one control element are moveably disposed, wherein a control gearing connects the actuator to the positioning element to move the at least one control element.

10 . The control unit according to claim 9 , characterized in that the control gearing has a spindle gearing.

11 . A device for changing or maintaining the position of a first vehicle part, manually and/or with an electric motor, in relation to a second vehicle part, that has
a control component that has a joint such that it can be pivotally disposed on the first vehicle part, wherein the control component is to be placed on the first vehicle part such that when the vehicle parts are moved in relation to one another, the control component moves in relation to the second vehicle part, an output drive element placed on the second vehicle part, functionally connected to the control component, which can be driven to move the control component in relation to the second vehicle part, and an electric motor drive mechanism for driving the output drive element, wherein the drive mechanism has a drive motor and a gearing that couples the drive motor to the output drive element, characterized in that the gearing has a switching mechanism, configured to switch the gearing between a coupling state, in which the drive motor is coupled to the output drive element, a freewheel state, in which the coupling between the drive motor and the output drive element is interrupted such that the drive element can move independently of the drive motor, and a braking state, in which the output drive element can move independently of the drive motor, but is braked thereby.
