Abstract:
A method of operating a torque transfer system in a motor vehicle; said torque transfer system including a shifter device with a movable element that is movable into a plurality of shift positions, an actuator device operable to apply an actuating force to the movable element, a control device to control the actuator device, and a position-detecting device to detect a position of the movable element; wherein said shift positions comprise positions of minimum potential energy, so that the movable element will have a tendency to fall into a nearest one of said shift positions; the method comprising the steps of:generating an output signal from the control device to the actuator device with the end purpose of moving the movable element to a position within a first tolerance band of a targeted shift position; ceasing to generate said output signal when the movable element has arrived within a second tolerance band that is wider than and includes the first tolerance band, said second tolerance band representing a range of positions where said tendency will at least attempt to cause the movable element to move into and settle within the first tolerance band.
