The device for controlling a pull-type solenoid (10) with a potentially varying air gap width (h) comprises the brief application of a voltage (U) to the exciter coil (16). The duration for which the voltage is applied is dependent on the potentially varying air gap width (h) of the pull-type solenoid (10). This has been ascertained in a measurement phase by analysis of the decay behavior of a briefly applied measurement voltage. This analysis in turn is performed on the basis of the time constant tau of the decay behavior of the measurement voltage. The value of the time constant tau is defined inter alia by the air gap width (h), such that it is thus possible to determine said air gap width (h) and to accordingly select the control signal that leads to the defined haptic profile of an operator control element (22) of a vehicle operator control unit.

OPERATING UNIT FOR A VEHICLE COMPONENT, IN PARTICULAR HUMAN-MACHINE INTERFACE FOR A VEHICLE
The invention relates to an operating unit (10) for a vehicle component, which operating unit has a housing (14) having a frame (16) and a display (62), which has a transparent cover pane (18) having an edge (22). A plurality of actuators (24) for introducing flexural waves into the cover pane (18) is arranged along the edge (22) of the cover pane (18). A contact surface (34) is associated with each actuator (24) on the cover pane (18), by means of which contact surface the actuator (24) acts on the cover pane in order to introduce flexural waves into the cover pane (18). The flexural waves introduced into the cover pane (18) by the actuators (24) are superposed in the cover pane (18) and give the cover pane (18) a tactilely sensible, locally resolved surface structure. The contact surfaces (34) are each arranged at a distance from the frame (16) of the housing (14), and consequently the introduction of flexural waves into the cover pane (18) and/or the propagation of flexural waves in the cover pane (18) is damped for wavelengths or frequencies resulting from the magnitude of the distance. The distance is selected in such a way that flexural waves having frequencies in the audible frequency range are damped.
The operating unit comprises an actuator (24) which mechanically excites an operating element (14). The actuator (24) comprises a support strip (32) made of a resilient material. Piezo elements (34, 36), which are connected to the support strip (32) in a shear-resistant manner, are located on both outer surfaces (42, 46) thereof. As a result of the alternate arrangement of the piezo elements (34, 36), the support strip (32) assumes an undulating form (56) when moving out of its inactivated state. One side of the support strip (32) is mechanically connected to the operating element (14) and the other side is mechanically connected to a counterbalance (30). The support strip (32) itself is mechanically fixed in the housing (12). In its inactivated state, the operating element (14) and the counterbalance (30) 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 (12).
The operating device for a vehicle is provided with a capacitively operating touch panel (16) which has an upper face (58) having a touch-sensitive surface, and with an operating unit (18, 18') which has a movable operating element (22, 22'), which can be grasped manually and has an electrically conductive surface, and a planar holding element (24) which is provided with an upper face and a lower face facing away from the upper face and on which the operating element (22, 22') is movably mounted and which for its part is arranged on the touch-sensitive surface of the upper face of the touch panel (16).

The device is provided with an evaluation unit (26), which receives the signals of all sensors and, for the purpose of calibrating the moisture sensor (32), associates the output signal of the moisture (32), which the moisture sensor emits if moisture that has precipitated on the condensation surface (16) is detected by the condensation sensor (28), with the relative humidity that is obtained by computation from the output signals of the condensation surface temperature sensor (30) present in this state and the air temperature sensor (34).
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 activation 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 activation 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).
