Description

The invention relates to an operating device for a motor vehicle, in particular for an infotainment system of a motor vehicle, with a rotary / push button, at least serving as a vehicle-side interface support surface on which the rotary / push button for operating vehicle functions is magnetically held, and means for generating a locking action between adjacent rotational positions of the rotary / push button for haptic feedback to an operator.

The increasing use of some very complex electronic systems in motor vehicles results in the use of ever more complex controls, which in turn requires an increased level of attention from the operator, especially the driver, for the operation of the respective devices. To facilitate the operation and limit the number of controls in the vehicle is often trying to summarize several functions or controls in a control device, so that the driver's attention is not unnecessarily distracted by the search for the required control element from traffic.

From the state of the art for this purpose so-called rotary / push button are known, which have a rotatable ring and arranged in the middle of the ring pressure switch. Using the ring, for example, you can navigate in a menu and confirm the selection of the desired menu item by pressing the button. Angular locking positions of the ring provide feedback to the operator about the rotation.

The generic DE 10 2014 202 713 A1 describes an operating device with a rotary / push button magnetically held in and detachable from a vehicle-side interface, the rotary / push button having a plurality of permanent magnets whose magnetic field change detected upon rotation by the operator in the vehicle-side interface and to the infotainment system of Vehicle is transmitted. In this case, the generation of a locking action between adjacent rotational positions of the rotary / push button for haptic feedback to the operator is provided, which is implemented mechanically or electromechanically.

The object of the invention is to provide an operating device for a motor vehicle, which has over the prior art a simplified design for generating a locking action between adjacent rotational positions of the rotary control / push button.

According to the invention, this is provided in an operating device of the type mentioned, that the means for generating a detent effect comprise at least one arranged in the rotary / push button permanent magnets and at least one arranged in or below the support surface permanent magnets. These permanent magnets exert, depending on the polarity, an attractive or repulsive effect on each other, which is used according to the invention to transmit a haptic feedback about a rotation done or angle change of the rotary / push button to the operator. An (additional) mechanical or electromechanical influencing of the feel, as described in the prior art, does not occur, which is why the operating device according to the invention is characterized by a simple and cost-effective design. "Placed in the bearing surface" means that the permanent magnets terminate outwards with the bearing surface.

Preferably, a holder of the rotary / push plate is realized by a arranged in or below the support surface permanent magnets and a polar opposite thereto permanent magnets in the rotary / push button, said permanent magnets set at the same time the axis of rotation of the rotary / push button. By the permanent magnets also the exact position of the rotary / push plate is set on the support surface and its secure mounting allows. Moreover, the rotary / push button is easily removable from the support surface.

In a preferred embodiment, the rotary / push button on a flat circular cylindrical shape, in particular with a convex curved bottom on, is at least partially on the support surface and is designed to perform rotational, pushing, sliding and / or tilting movements. These movements correspond to different functions, such as tilt to the right "continue", tilting to the left "back" mean. For example, turning can navigate through a menu and press to select the desired menu item.

The means for generating a detent effect preferably have a plurality of permanent magnets distributed uniformly along the circumference of the rotary control / push-button in the rotary pushbutton and a plurality of permanent magnets arranged along the circumference of the rotary push-button under the contact surface. Due to the number and location of the circumferentially arranged permanent magnets in the rotary / push button number and position of the locking positions are set for the Haptikrückmeldung.

In particular, in the turn / push button and under the support surface the same number Permanent magnets provided, which are distributed according to the same pattern, whereby a particularly good locking effect is achieved.

In a preferred embodiment, the production of a detent effect serving permanent magnets in the rotary / push button on the same polarity as the associated permanent magnets under the support surface. Here, the magnetic poles repel each other in superposition; a locking action is thus achieved in the intermediate positions of the evenly distributed along the circumference of the rotary / push button magnets.

Alternatively, the production of a detent action serving permanent magnets in the rotary / push button may be oppositely poled as the associated permanent magnets under the support surface. In this case, the magnets in the rotary / push button and the magnets under the support surface on superposition, whereby the desired locking action is generated.

Preferably, at least one sensor is provided under the support surface, registers the movements of the rotary / push button and transmitted to a control unit of the vehicle. The control unit is preferably part of the infotainment system and adjusts the movement of the rotary control / push button corresponding setting on the infotainment system.

In a preferred embodiment, the sensor comprises at least one Hall sensor. In particular, two sensors are provided to determine both angle change and direction of rotation.

A particularly compact and cost-effective design can be achieved if the production of a detent action serving permanent magnets in the rotary / push button are simultaneously signal generator for detecting the rotation of the rotary / push button. Thus, the weight of the removable rotary control / push button can be reduced, which contributes to the secure determination of the rotary / push button especially in the event of a crash.

Advantageously, the operating device is provided for arrangement on a center console of the vehicle, in particular on an upper side of the center tunnel. In this way, it is easily accessible to the driver and operated with one hand, so that the driver's attention is not excessively distracted from the road. Even a "blind" operation of the operating device is facilitated by the central arrangement.

In a further development, a plurality of support surfaces serving as vehicle-side interfaces are provided in the vehicle, to which the rotary / push-button actuator can be placed to operate different vehicle functions and from which it can be removed. As a result, many buttons or other operating devices in the vehicle interior can be omitted, and different devices, even at different input locations (for example, air conditioning, ...), can be equipped with the same user interface. This is of course ensured that the rotary / push button has a low weight and sufficient magnetic fixation to prevent a possible hazard in the event of a crash.

In addition, one or more input keys can be provided on the support surface around the rotary / push button, which serve as a direct selection keys for frequently used functions. Preferably, the input keys are arranged outside the support area of the rotary control / push button, in particular around it, and thus easily accessible to the operator. Common features include multimedia, radio, navigation, phone, menu, back, and more options.

• - 2 a perspective view of the operating device 1 in which the turn / push button is lifted off the support surface; and
• - 3 a schematic representation of the magnet assembly in the operating device 1 , in which the support surface from above and the turn / push button is shown from below.

1 shows an operating device according to the invention 10 for an infotainment system of a motor vehicle, which is in the area of a center console 12 of the vehicle, more precisely on the top of the center tunnel, is arranged. The operating device 10 has a turn / push button 14 which is designed to perform rotational and pushing movements. For this purpose, the rotary / push button has 14 a substantially flat circular cylindrical shape with a ring-like, arched upper edge.

The turn / push button 14 is to operate vehicle functions on serving as a vehicle-side interface support surface 16 arranged and held magnetically on this. As 3 can be seen, is the holder of the rotary control / push button 14 doing so by one in or under the support surface 16 arranged permanent magnets 18 as well as an oppositely poled permanent magnet 20 in the turn / push button 14 realized, these permanent magnets 18 . 20 at the same time the axis of rotation D of the rotary control / push button 14 establish. In the example shown, the North Pole pulls N of the permanent magnet 18 under the support surface 16 the South Pole S of the center in the turn / push button 14 arranged permanent magnets 20 and thus forms a predetermined fixing position for the turn / push button 14 , which are centered in the bearing surface 16 located. Preferably, the bearing surface is 16 designed as a trough in which the turn / push button 14 lies.

To turn the rotary control / push button 14 to convey a haptic feedback on the completed rotation to the operator, the operating device 10 continue funds 22 for generating a locking action between adjacent rotational positions of the rotary / push plate 14 on, the at least one in the turn / push button 14 arranged permanent magnets 24 and at least one under the support surface 16 arranged permanent magnets 26 include.

In the embodiment shown, a plurality (four exemplarily here) are along the circumference U of the rotary control / push button 14 evenly distributed permanent magnets 24 in the turn / push button 14 and several (here also four) along the circumference U of the rotary control / push button 14 under the support surface 16 arranged permanent magnets 26 intended. Here are the permanent magnets 24 and 26 distributed according to the same pattern and determine the number and position of the detent positions for the Haptikrückmeldung.

The permanent magnets 24 in the turn / push button 14 and the associated permanent magnets 26 in or under the support surface 16 are poled so that they repel each other in superposition (in the example shown, the magnetic south poles S to each other). A locking action is thus in the intermediate positions of uniformly along the circumference of the rotary / push plate 14 distributed magnets 24 or. 26 reached.

Alternatively, of course, a different number or distribution of the permanent magnets 24 or. 26 conceivable. For example, the rotary / push button could 14 only a single one near the perimeter U arranged permanent magnets 24 while under the bearing surface 16 several evenly spaced permanent magnets 26 are arranged. Of course, the polarity of the permanent magnets 24 and 26 also be chosen so that when superimposed an attractive effect.

Under the support surface 16 is a sensor 28 provided here, which includes two Hall sensors, with their help movements of the rotary / push button 14 (Angle change and direction of rotation) registered and transmitted to a not shown in the figures control unit of the vehicle. The control unit is in particular part of the infotainment system and assumes the movement of the rotary control / push button 14 corresponding setting on the infotainment system.

Here, the permanent magnets act 24 in the turn / push button 14 in addition to the generation of the locking action at the same time as a signal generator for detecting the rotation of the rotary / push button 14 , Due to the use of permanent magnets, it is also possible to supply power to the turn / push button 14 to renounce.

As 2 can be seen, is the turn / push button 14 from the support surface 16 removable. In particular, several serving as vehicle-side interfaces bearing surfaces 16 provided in the vehicle, on the turn / push button 14 for the operation of different vehicle functions can be placed and from which it is removable. In this way, can be dispensed with a number of buttons or other operating devices in the vehicle interior, and different devices, even at different input locations, can be equipped with the same user interface.

The turn / push button 14 is in particular designed as a compact component (ie without a rotatable ring or the like), for example made of stainless steel and as a whole on the support surface 16 rotatable and removable from this. An undesired release of the rotary / push button 14 from the support surface 16 in the event of a crash, for example, can be prevented by an electromechanical coupling.

If that of the bearing surface 16 facing underside of the rotary push button 14 convex is curved, for example, in the center, the rotary / push button can 14 also be tilted. The magnetic attraction of the central permanent magnets 28 However, it is so big that these tilted turn / push button 14 always in the vertical position to the support surface 16 back flips.

The operating device 10 is preferably exclusively for the input of commands and is combined in the vehicle with a separate display device, which is located in the driver's field of vision, approximately in the upper part of a dashboard.
