Description

Described are an operating device of a motor vehicle, a motor vehicle and a method for operating a motor vehicle.

Operating devices, motor vehicles and methods for operating a motor vehicle of the type mentioned are known in the art.

Due to the large number of different operating options in a modern motor vehicle, a large number of different operating concepts are used today, all of which have the goal of enabling intuitive and distraction-free operation of functions of the motor vehicle.

A classic principle is to provide dedicated controls for different functional groups, for example air conditioning, multimedia, vehicle control, assistance systems and the like.

An alternative way is to control a plurality of the aforementioned and other options by means of a common operating element. For this purpose, for example, so-called rotary push-turn or rotary push-slide actuator are known, which are often arranged in the center console of a motor vehicle. The disadvantage of this, however, is that the necessary menu depth for addressing all required functions is large, so that the interaction with appropriate controls takes a long time and thus on the one hand has a greater distraction potential and on the other confusing and prone to error, since the sought setting is difficult to find.

Another known technology is the use of touch screens in which the driver (or other occupant) selects certain functions by pressing on certain areas of the screen. As a result, on the one hand over time, the screen is contaminated by skin fat and the like, and on the other hand, pressing the corresponding area requires great precision, so that erroneous operations are likely.

From the US 2013/0127911 A1 is a method for interacting with a dial-based interface known wherein the dial has a display with multiple depressible operating areas. Such an interface has only a limited display area and is therefore difficult to operate.

Thus, the task of further developing operating devices, motor vehicles and methods for operating a motor vehicle to the effect that a simpler, safe and intuitive operation of functions of a motor vehicle is possible.

The object is achieved by an operating device of a motor vehicle according to claim 1, a motor vehicle according to the independent claim 8 and a method for operating a motor vehicle according to the independent claim 9. Further developments and further developments are the subject of the dependent claims.

Described is an operating device of a motor vehicle with a screen and a control element, wherein the control element is rotatably supported on the screen, wherein the control element is displaceable in at least one further different zone of the screen, wherein the control element is rotatable about a parallel to a normal screen rotation axis.

Depending on the position of the operating element on the screen, the control element can be used to address different functions. The zones of the screen may be provided for different purposes, such as air conditioning, vehicle control, multimedia, navigation, and the like. The zones of the screen can also lead to different submenus, which in turn have their own zones or the same zones.

By rotating the control element about its axis of rotation, control commands can then be generated which influence the corresponding systems, for example higher or lower, e.g. at a volume or temperature, or selection of different alternatives, e.g. Radio stations.

When using the control element for multimedia control can thus serve, for example, a zone for volume control. Another zone may affect sound settings. A third zone can be used to select multimedia content or radio stations to play. In this case, zones can also be defined as polygons that delimit setting options with each other, such as individual seats for the seat settings or country / city limits when entering the destination in the navigation.

When using the control element for air conditioning control, for example, zones for each seating area (for example, driver's seat, front passenger's seat and rear seat) may be provided, in which one can set temperatures and / or ventilation individually.

The control element can be made detachable in a further embodiment of the screen.

The screen may be sensitive to touch in another further embodiment, so that it can be additionally operated with one or more fingers.

In a first further embodiment, it may be provided that the operating element has at least one magnet, wherein the screen is also magnetic. In this way, the control can be held by magnetic forces on the screen, but at the same time with only little force in the screen plane back and forth.

In another further embodiment, it can be provided that the screen has at least one magnetic sensor for detecting the position and rotation of the operating element. Thus, on the one hand, the screen can distinguish between the different zones, that is to say, in which zone the operating element is arranged at the moment and, on the other hand, recognize the position of the operating element, ie its rotational position. Suitable sensor technology, for example Hall sensors in question.

In a further embodiment, it can be provided that the magnetic field emanating from the screen is substantially homogeneous on the surface, in order to allow free movement of the operating element on the screen.

In an alternative further embodiment, it can be provided that the magnetic field emanating from the screen defines a plurality of regions of different strengths in which the operating element is centered. In these areas, the control element engages magnetically, so that the locking force must be overcome to move. By means of such a centering can be realized in addition to pure rotary gestures and rotary-push gestures.

In another further embodiment, it can be provided that the operating element can be pressed in the direction of its axis of rotation. In the context of this embodiment, the operating concept is extended to rotary-push gestures or rotary-push-push gestures, which makes the operating concept more intuitive.

In another further embodiment, it can be provided that the operating element is de-energized. In this case, all power consumers can concentrate on the lighter powered screen and the control can be passive. This prevents, for example, the failure of the control element in the event that its power storage is empty, for example, by empty batteries or accumulators.

In another further embodiment, it can be provided that the control element is equipped with an accumulator and can be charged by wireless energy transmission, for example by inductive method.

In another further embodiment, it can be provided that the screen has a magnetic glass. In this way, weaker magnets can be provided in the screen than in screens in which magnets are arranged behind a picture panel.

A first independent subject relates to a motor vehicle having an operating device of the aforementioned type.

Another independent object relates to a method for operating a motor vehicle, wherein the operating element is moved to a zone of the screen and rotated about its axis of rotation, wherein the current position and the rotation of the operating element are registered by the screen, wherein a corresponding operating command is generated.

A first further embodiment provides that the operating element is pressed, the pressing registered by the screen and a corresponding operating command is generated.

Further advantages, features and details will become apparent from the following description in which - where appropriate, with reference to the drawings - at least one embodiment is described in detail. The same, similar and / or functionally identical parts are provided with the same reference numerals.
