Abstract
The invention is directed to a control element, particularly for automotive electronics, having programmable haptics. Moments of force or a variation of the friction moments are formed on a control element by dynamically adapting the operative currents of electromagnetic arrays in dependence of the adjustment path. The force/path behavior (tactile feedback) of the control element can be modified at will during use so that the actuation forces for different operative functions can be varied. The tactile feedback of the moments of force on the control element takes by way of a locking piece, which, for example, can be comprised of at least one locking disc and a spring, which can be rendered active or inactive via an electromagnetic array.
Claims17
A control element comprising:
- a mechanical locking piece for adjusting a force/path behavior on the control element, the locking piece including:
- a disc having a fixed friction value, and
- a braking device on which a friction lever is connected, the friction lever being configured to impact the disc with variable forces;
- and
- at least one electromagnetic array being functionally coupled with the braking device to apply variable magnetic forces in a first direction to the friction lever,
- the variable magnetic forces urging the friction lever to impact the disc with the variable forces, which are substantially similar to the variable magnetic forces, in a second direction, which is parallel with the first direction, such that the force/path behavior is varied.
A control element, comprising:
- a single disc having a fixed friction value;
- a friction lever disposed at a periphery of the single disc;
- and
- an electromagnetic array coupled to and configured to apply variable magnetic force to the friction lever such that the friction lever is forced to impact an outer surface of the single disc with a variable level of force, which is substantially similar to the variable magnetic force, in a direction parallel to a direction along which the electromagnetic array applies the variable magnetic force to the friction lever.
A control element, comprising:
- a member having a fixed frictional value;
- a leverage providing part disposed proximate to the member;
- and
- an electromagnetic array coupled to and configured to apply variable magnetic force to at least one of the member and the leverage providing part such that the leverage providing part is forced to impact the member with a variable level of force, which is substantially similar to the variable magnetic force, in a direction parallel to a direction along which the electromagnetic array applies the variable magnetic force to the at least one of the member and the leverage providing part.
