Abstract
A motor vehicle drive assembly which is equipped with a drive element and an abutment, and also with at least one spring between the drive element and the abutment. In addition, there is at least one drive element sensor which, depending on the application of force by the drive element counter to the force of the spring and an associated relative movement between the drive element and the abutment, transmits sensor signals to a control unites. According to the invention, the drive element sensor, depending on the application of force by the drive element, generates different force-dependent, sliding sensor signals which are evaluated by the control unites, for example to drive an actuating element.
Claims17
A motor vehicle drive assembly comprising:
- a drive element;
- an abutment;
- at least one spring between the drive element and the abutment;
- at least one drive element sensor;
- a control unit, wherein the at least one drive element sensor, depending on an application of force by the drive element counter to a force of the spring and an associated relative movement between the drive element and the abutment, transmits sensor signals to the control unit;
- and
- an actuating element connected to the drive element, wherein the drive element sensor, depending on the application of force by the drive element, generates different force-dependent, sliding sensor signals which are evaluated by the control unit to drive the actuating element, wherein the sliding sensor signals includes an anti-trap signal,
- wherein the control unit is configured to receive additional sensor signals from an actuating element sensor to determine a position of the actuating element,
- wherein the control unit is configured to stop or reverse the drive element in response to the anti-trap signal when the control unit detects the position of the actuating element is within a first position range, and
- wherein the control unit is further configured to ignore the anti-trap signal and continue operating the drive element to move the actuating element when the control unit detects the position of the actuating element is within a second position range,
- wherein the sliding sensor signals further includes an overload signal for the actuating element,
- wherein the anti-trap signal corresponds to a compression of the at least one spring and a first force threshold being exceeded during the application of force by the drive element counter to the force of the at least one spring, and
- wherein the overload signal corresponds to further compression of the at least one spring and a second force threshold being exceeded during the application of force by the drive element counter to the force of the at least one spring.
