ABSTRACT:
A vehicle steering input device includes a fixed housing, a steering input shaft rotatable relative to the housing by a vehicle operator, a hub non-rotatably mounted on the input shaft, a friction member frictionally engaging the hub, a resilient member biased to maintain the friction member in engagement with the hub member, a movable locking ring meshingly coupled to the friction member, and an electromagnet. When the electromagnet is energized it moves the locking ring into meshing engagement with the housing, thus limiting rotation of the friction member and creating an additional friction force which makes it more difficult to rotate the hub and the input shaft. The magnitude of this friction force depends on the bias of the resilient member and is not limited by the strength of the electromagnet.
