Operating unit for a device, in particular for a vehicle component
The operating unit comprises an actuator, which mechanically excites an operating element. The actuator comprises a support strip made of a resilient material. Piezo elements, which are connected to the support strip in a shear-resistant manner, are located on both outer surfaces of the support strip. As a result of the alternate arrangement of the piezo elements, the support strip assumes an undulating form when moving out of its inactivated state. One side of the support strip is mechanically connected to the operating element and the other side is mechanically connected to a counterbalance. The support strip itself is mechanically fixed in the housing. In its inactivated state, the operating element and the counterbalance are at a different distance from one another than in the undulating activated state, wherein they move in opposite directions and thus lead to a compensation of dynamic forces acting on the housing.
An infotainment system having an operating element for a vehicle is disclosed. The operating element is mounted in a spring-elastic manner with springs on and/or in a housing along a vertical axis of movement. One or more sensors for detecting an actuating movement of the operating element can also be included. The operating unit can further have an actuator arranged in and/or on the housing for feedback movement of the operator control element. Torques acting at a center of mass of the operating element as a result of the return spring elements can cancel one another out, with the result that during the feedback movement of the operating element along the axis of effective movement of the drive element of the actuator said operating element does not additionally rotate or tilt.

The rotary control unit to which the invention relates, in particular nominal value rotary control unit for a vehicle heating system and in particular vehicle air conditioning system, is provided with a rotatable rotary control element (14), an electric motor (16) with a driveshaft (17) which is mechanically coupled to the rotary control element (14), an control circuit (24) for supplying the electric motor (16) with power for the purpose of generating a holding moment in order to prevent undesired rotation of the rotary control element (14) and/or to build up a resistance as the rotary control element is rotated, and a sensor unit (22) for detecting a hand which is approaching the rotary control element (14) or is touching the rotary control element (14). The control circuit (24) for supplying power to the electric motor (16) can be activated if the sensor unit (22) detects a hand which is approaching the rotary control element (14) or is touching the rotary control element (14).
In a method for the detection of the rotational position of the rotor of a DC motor with commutator by evaluating the time development of a rotor current signal of the DC motor, said signal comprising a periodic waviness around an average value and comprising current ripples generated by commutation which are superimposed to said waviness, the rotor current signal of a current ripple detector unit (30) is supplied for detecting the current ripples of the rotor current signal. The rotor current signal is further supplied to a waviness detector unit (34) for detecting a half or full wave of the rotor current signal. The current ripple detector unit (30) is arranged to output a current ripple pulse for each detected current ripple. The waviness detector unit (34) is arranged to output a waviness pulse for each period of the waviness. The output signals of both detector units (30,34) are supplied to a logic OR unit (38) for generating a logic signal. Within a period of the rotor current signal, at least one of the detector units (30,34) will output a pulse. Thereby, the logic signal comprises a logic pulse for each period of the rotor current signal.
