Abstract
A control element is provided having programmable haptics, in particular a programmable central catch, for a motor vehicle, having a control knob which can be accommodated such that it can rotate, the control knob being connected in a force-fitting or interlocking manner to a toothed ring or having an integral design, and it being possible for the toothed ring (to be rotated by means of the control knob, and at least one latching element which can move towards the toothed ring and/or away from the toothed ring by means of an electromagnet.
Claims14
An operating element having programmable tactile feedback, in particular a programmable center detent, for a motor vehicle, the operating element comprising:
- a rotatably supported control knob, the control knob being connected to a toothed ring in a frictional or interlocking manner or being a single piece therewith, the toothed ring being rotatable by the control knob;
- and
- at least one detent element that is movable toward and/or away from the toothed ring by an electromagnet, the detent element abutting the electromagnet when moved away from the toothed ring and the detent element and the electromagnet being disposed within the tooothed ring.
An operating element having programmable tactile feedback, the operating element comprising:
- a rotatably supported control knob,
- a toothed ring rotatable with the control knob;
- at least one detent element;
- and
- an electromagnet operably connected to the at least one detent element for moving the at least one detent element relative to the toothed ring, the detent element abutting the electromagnet when moved away from the toothed ring,
- wherein the detent element and the electromagnet are disposed within the tooothed ring and the electromagnet is configured to move the detent element toward the toothed ring with a first level of force when the toothed ring is in a first range of angular positions relative to the detent element and to move the detent element toward the toothed ring with a second level of force greater than said first level of force when the toothed ring is in a second range of angular positions relative to the detent element to define a center detent in the second range of angular positions.
