摘要:
A torque transfer system, particularly an automated shift transmission of a motor vehicle, has a movable shifter element that is subject to a position-dependent force. The gear positions of the transmission correspond to minima of potential energy of the position-dependent force, so that the movable element will have a tendency to fall into the nearest one of the shift positions. To perform a gear shift, the movable shifter element is moved into the vicinity of the targeted gear position by means of a control device directing a shift actuator. When the movable shifter element has stopped moving within a given tolerance band of the targeted position, the control device generates a stall-releasing signal, e.g., a series of pulses of alternating polarity to overcome a holding force or holding torque of the movable element, so that the latter will seek a position of minimum potential energy and thus move towards the targeted gear-shift position.
