Abstract: A control knob for use in a motor vehicle is provided, having a hub for attachment of the control knob to a shaft, a torsion-proof part, a rotatable part, a rotation angle sensor, means for generating rotary haptics, and an electronic system by means of which the components, located in the control knob, can be controlled and the signals of the sensors can be evaluated and via which the control knob can be connected to the on-board electronics of the motor vehicle.

Abstract: A sensor arrangement is provided for determining an interior temperature in a motor vehicle, which sensor arrangement is at least one part of an air-conditioning operating part, comprising a closed housing having at least one front wall and one rear wall, wherein the front wall is manufactured from a material which ensures satisfactory thermal transfer and the housing and is filled with a thermally insulating means, further comprising a first temperature sensor which is fastened to a rear side of the front wall and a second temperature sensor which interacts with the first temperature sensor at least in relation to an evaluation of the interior temperature, wherein the at least second temperature sensor is fastened on an inner side of the rear wall which faces the rear side of the front wall.

Abstract: An operating element is provided that has a control knob, which is mounted in a housing, a console, or the like, and can move in a swiveling manner between a home position and multiple switching or contact positions. In order to design the operating element in a simple way, a central momentary switch that establishes the switch actuation point of the operating element and has a haptic function is associated with the control knob, and the momentary switch is actuated each time the control knob is swiveled out of its home position by a predefined angle toward a switching or contact position.

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.

Abstract: An operating element is provided, in particular a joystick, with tilt haptics for a motor vehicle, having a tiltably supported lever with one primary lever arm and at least one secondary lever arm, as well as at least one pair of permanent magnets, wherein one magnet of a permanent magnet pair is located on a secondary lever arm and one magnet is located in a fixed position in the operating element in such a manner that unlike poles of the magnets are located opposite and a distance apart from one another when the operating element is in its center position.

Abstract: A control knob for use in a motor vehicle is provided, having a hub for attachment of the control knob to a shaft, a torsion-proof part, a rotatable part, a rotation angle sensor, means for generating rotary haptics, and an electronic system by means of which the components, located in the control knob, can be controlled and the signals of the sensors can be evaluated and via which the control knob can be connected to the on-board electronics of the motor vehicle.

Abstract: A rotary actuator is provided for a motor vehicle, having a control knob, a housing, an actuating shaft that is rotationally fixed to the control knob, and electromagnetic means that act on the control knob so as to permit a detent or locking of the rotation of the control knob, wherein a coil is arranged in the housing in a rotationally fixed manner, and a disk-shaped flux guide is attached to the actuating shaft so as to be rotationally fixed and movable along the actuating shaft, and the flux guide can be pressed against the coil and/or the housing.

Abstract: In actuating devices such as, e.g., multifunctional actuators, it is necessary in many cases to block at least one specific direction of movement. A simple and reliably operating device is proposed for this purpose, which uses an electromagnet to bring a ball from a rest position into a blocking position. In the blocking position, the ball mechanically blocks the relative movement between two parts.

Abstract: The invention concerns an operating element, in particular a pushbutton, for a motor vehicle, having at least of a touch-sensitive pushbutton operating on a capacitive basis and a housing, wherein the pushbutton is movably mounted in the housing, wherein a capacitor that forms the capacitance is composed of a metallic area applied to an inner or outer side of a surface facing the user, and the metallic area forms an electrode of the capacitor that is electrically contacted in the housing.
