The operating unit for a vehicle, in particular for a vehicle component, is provided with a housing () which has an operating element (), such as a display for example, and is designed to be secured in a device, in particular in a vehicle dashboard. The operating element () is elastically mounted on the housing (). An actuator () is additionally provided for mechanically exciting the operating element () when an operation of the operating element () has been detected. Finally, the operating unit also has a vibration compensating mass () which can be mechanically excited by the actuator or by one actuator () when an operation of the operating element () has been detected and/or which is mounted on the housing () and can be moved in order to substantially compensate for forces acting on the housing () when the operating element () is moved.

Operating unit for a device, in particular for a vehicle component

The operating unit for a device, in particular for a vehicle component, is provided with a housing () that has a control panel () and is provided for attaching in an apparatus, in particular a vehicle dashboard or vehicle center console, the control panel () being elastically mounted on the housing (). Furthermore provided is an actuator () for mechanically exciting exclusively the control panel () when use of the control panel () is detected, the control panel forming the front side of a touch-sensitive touch panel (). Finally, the operating unit also comprises a vibration compensation mass () that is mechanically excitable by the or by an actuator () when use of the control panel () is detected and is elastically mounted in and/or on the housing () and is movable to essentially compensate for a movement of the housing () when activating the actuator () that can mechanically excite the control panel (). The operating unit has a backlit display () that has a display unit () and a backlight unit () separate therefrom. The backlight unit () or the display unit () can operate individually or together as vibration compensation masses ().

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.

The operating unit for a device, particularly for a vehicle component, is provided with a housing that has an operating panel and is provided for attachment in an apparatus, particularly a vehicle dashboard or vehicle center console, the operating panel being elastically mounted on the housing. Further, an actuator for mechanically exciting the operating panel when use of the operating panel is detected is provided. Finally, the operating unit also has a vibration compensation mass that is mechanically excitable by the or by an actuator when use of the operating panel is detected and is elastically mounted in and/or on the housing and is movable to essentially compensate for a motion of the housing when the actuator mechanically exciting the operating panel is activated. The operating unit has a backlit display that has a display unit and a backlight unit separate therefrom. The backlight unit serves as a vibration compensation mass.

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.

Operating unit for a vehicle

The operating unit for a vehicle is provided with a housing with a front face and an operating element arranged on the front face of the housing and having a center of gravity and an operating surface. Said operating element is mounted on and/or in the housing in a spring-elastic manner along a vertical axis of movement extending essentially orthogonally to the operating surface and along a lateral movement axis extending essentially transversely with respect thereto. At least one sensor for detecting an actuation movement of the operating element in the direction of the vertical movement axis is provided. Also, the operating unit comprises an actuator arranged in and/or on the housing for feedback movement of the operating element at least also in the lateral movement axis during a detected actuating movement of the operating element, wherein the actuator comprises an electromagnetically controllable drive element which is mechanically coupled to the operating element which can be moved back and forth along a movement axis. The center of gravity of the operating element lies on the movement axis of the drive element of the actuator.

The operating unit for a vehicle is provided with a housing with a front face and an operating element which is arranged on the front face of the housing and has an operating surface. The operating element is mounted in a spring-elastic manner. Furthermore, at least one sensor is provided for detecting an actuation movement of the operating element. The operating unit additionally has at least one actuator for the feedback movement of the operating element in the case of an actuation movement of the operating element detected by the sensor as well as an analysis and control unit which is connected to the at least one sensor and to the actuator. The actuator is designed as an armature-type electromagnet with a first stator which has a first excitation coil, and an armature as a drive element. Furthermore, the armature is provided with a measuring coil to which a measuring voltage is applied when the magnetic flux generated by the first excitation coil flows through the armature. The first excitation coil and the measuring coil are connected to the analysis and control unit, and with the analysis and control unit it is possible to apply open-loop and/or closed-loop control to the force with which the armature of the actuator can move towards the first stator and/or the displacement movement of the armature out of its rest position and the return movement of the armature back into its rest position are adapted to be controlled and/or regulated.
