  • Patent number: 11961665
    Abstract: The invention relates to a device for controlling armature solenoid provided with a DC voltage source (14), at least one buffer capacitor (18), which is connected in parallel to the DC voltage source (14) and has a known capacitance (C), and a first switch (28), which is arranged between the DC voltage source (14) and the buffer capacitor (18). The exciter coil (16) and a second switch (30) arranged in series therewith are connected in parallel to the buffer capacitor (18). A control and evaluation unit (22), when the buffer capacitor (18) is charged, opens the first switch (28) and closes the second switch (30) in order to determine, on the basis of the measurement voltage (20), the frequency of the resonant circuit having the capacitance (C) of the buffer capacitor (18) and the inductance (L) of the armature solenoid (12).

  • Patent number: 11888372
    Abstract: The operating unit for a vehicle is provided with a housing and an operating element elastically mounted in and/or on the housing, wherein the elastically mounted operating element forms a spring-mass system having a construction-related resonance frequency. The operating unit is further provided with an actuator for pulse-shaped mechanical excitation of the operating element, and a control unit for controlling the actuator when manually actuating the operating element. The resonance frequency is, due to construction, above the highest cut-off frequency that can typically still be detected by receptors for haptic feedback and/or for tactile sensation of a person. The frequency spectrum of the mechanical pulse at the resonance frequency and/or at one of the harmonics of the resonance frequency has no frequency components in that the power density spectrum above the cut-off frequency is energy-free or substantially energy-free.

The piezo driver comprises a piezo actuator made from a piezoelectric material. The longitudinal extension ends of the piezo actuator have mechanically coupled thereto a conversion gear for converting a length change of the piezo actuator occurring in the effective direction of the piezo actuator into a movement of an element, which is coupled to the conversion gear and to be moved, at an angle not equal to 0 degree relative to the longitudinal extension of the piezo actuator. The conversion gear comprises a first bracket which is of an elastic configuration and/or comprises an elastic material and which, in the area of the longitudinal extension ends of the piezo actuator, is mechanically coupled to the latter.

  • Publication number: 20210296563
    Abstract: The piezo drive is provided with a piezo actuator which can be reversibly expanded with respect to its longitudinal extent and has two ends which are averted from one another and also has two lateral sides which are averted from one another. A conversion transmission is coupled to the piezo actuator for converting an expansion and a subsequent contraction of the piezo actuator into in each case a movement which is directed at an angle which is not equal to 0 degrees, in particular of 90° in relation to the longitudinal extent of the piezo actuator. The conversion transmission has an elastic clip which has two receiving legs, which are situated opposite one another and are at a distance from another, and a connecting which extends between said receiving legs and has at least one section which is directed away from the piezo actuator with respect to the position of said piezo actuator or a section which is bent in the direction of said piezo actuator.

  • Patent number: 11001147
    Abstract: 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.

  • Patent number: 10866644
    Abstract: The operating unit (10) for a vehicle component is provided with a housing (14) having a frame (16) and a display (62) having a transparent cover pane (18) with 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 assigned to each actuator (24) on the cover pane (18), by means of which contact surface the actuator (24) acts on the cover pane (18) 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.
