Description

The invention relates to a motor vehicle having a touchscreen, that is to say a touch-sensitive and / or proximity-sensitive screen, as well as a holding device for the touchscreen.

In today's motor vehicles, a screen without touch sensors is usually provided on or in the dashboard. To select graphical objects on the screen, so z. B. of menu items or icons, in the center console on the center tunnel of the motor vehicle then usually a rotary-push-button or a touchpad is provided as a selection element. This has the advantage that you can easily operate the selection element by hand, while lying with the arm on an armrest on the center tunnel. At the same time, the screen is ideally located in the field of vision or field of vision above the armrest on the dashboard.

Another common design philosophy in the automotive industry is the operation of devices of the motor vehicle, such as the infotainment system, by means of a touch screen. This also represents the screen and the selection element for selecting graphical objects on the screen. The advantage here is that you can intuitively select on the screen a specific graphical object, for example by pressing the object and thus activate the corresponding function of the motor vehicle. The disadvantage here is that a compromise between the readability of the screen, so its arrangement in the field of vision of the driver, and the accessibility by hand must be found.

From the DE 10 2011 112 115 A1 is a rail for the displacement of a functional part in an interior of a motor vehicle known. With the rail, a separate adapter is clamped connectable and it serves as the adapter for receiving the functional part.

The invention has for its object to provide an operating device for at least one device of the motor vehicle, such as an infotainment system in a motor vehicle.

The object is solved by the subject matters of the independent claims. Advantageous developments of the invention will become apparent from the features of the dependent claims.

The invention provides a motor vehicle with a touchscreen and a holding device for the touchscreen. The holding device is designed to alternately hold the touchscreen in two different holding positions in the motor vehicle. In the first stop position, the touchscreen for displaying display contents, ie as a screen, is held on or in a center console of the motor vehicle. In contrast, in the second stop position, the touch screen for receiving touch signals or approach signals is held or shifted closer to a rear of the motor vehicle and / or driver's seat of the motor vehicle compared to the first stop position. The touch screen is closer to the driver.

With the motor vehicle, the method also provided by the invention is implemented, which is used to operate a touch screen in a motor vehicle. According to the method, the touchscreen is thus alternately held by the holding device in the motor vehicle in a first holding position for displaying display contents in a field of vision of the driver of the motor vehicle or in the center console of the motor vehicle. The driver therefore only has to avert his gaze slightly away from driving, for example less than 50 °, in order to look at the touch screen. In contrast, in the second stop position, the touch screen is held closer to a rear and / or driver's seat of the motor vehicle compared to the first stop position. Here, the touchscreen then serves to receive touch signals or proximity signals. While the touch screen is in the first hold position for displaying display contents, the touch screen may not necessarily be manually reachable by the driver when the driver is leaning back in his driver's seat and touching the back rest with his shoulders. Preferably, the touch screen is placed in the second holding position of the touchscreen lying below a driver's hand, when the driver has placed his hand on an armrest of the motor vehicle, which is located on the center tunnel of the motor vehicle. The touchscreen can then be operated with a raised arm. The holding positions are in particular rest positions.

The invention provides the advantage that one and the same operating device, namely the touch screen, is used in the motor vehicle for two different operating scenarios and in each case the advantages for each operating scenario can be implemented without compromise. As a screen, the touch screen in the first stop position in the field of view of the driver can be arranged as a touch or proximity-sensitive disc, the touch screen can be located below the driver's hand near his fingers.

It can certainly be provided that a minimum distance between the two holding positions at least 20 cm, in particular 30 cm, is. The touchscreen can be moved from the first to the second holding position and also from the second to the first holding position. In particular, the first stop position is closer to a frontal windshield of the motor vehicle than the second stop position. In particular, the first stop position is higher than the second stop position.

According to a development of the motor vehicle according to the invention, the touch screen is located deeper in the second holding position than in the first holding position and thus closer to an arm rest for a driver of the motor vehicle. This makes the touch screen easier to reach by hand.

A refinement of the motor vehicle provides that the holding device is designed to keep the touchscreen upright in a first holding position and in the second holding position, in particular on a center tunnel of the motor vehicle. The latter simplifies typing with the finger. By upright is here meant that a surface normal of the display surface of the touch screen is arranged in a horizontal plane or at least outweighs the horizontal portion of the normal vector. In this case, lying down means, in contrast to upright, that the normal vector of the display surface points vertically upwards or at least a portion of the normal vector pointing vertically upwards predominates.

According to one development of the motor vehicle according to the invention, a control device is provided which is designed to operate the touchscreen in the first stop position as a display screen and in the second stop position as a touchpad. In other words, graphic objects, for example icons or list entries, are displayed by the touchscreen in the first stop position, which can then be selected by means of another selection element, for example a rotary-push-button or a touchpad. By contrast, in the second holding position, the touchscreen itself is operated as a touchpad, that is to say it can be provided with touch or proximity control for the selection of objects, ie the user can select objects on the touchscreen directly with his or her finger using a finger approaching or touching one of the graphical objects.

As already stated, it is not necessary for the driver to be able to touch the touchscreen in the first stop position from a normal sitting position while driving. In this context, a further development of the invention provides that an operating element to be actuated manually by the driver, for example the described rotary pushbutton, is released by the touchscreen in the first stop position, so that vehicle functions displayed on the touchscreen by means of this operating element, which are represented there by the graphical objects, can be selected and / or activated. This control element can then represent the selection element described. In this development, it is provided that in the second holding position, ie when the touchscreen is located below the driver's hand, the touchscreen covers the operating element. This effectively avoids incorrect operations.

In this case, a development provides that the operating element is extended in the first holding position of the touchscreen from the center console of the motor vehicle, so that it can operate the driver by hand, and in the second holding position of the touch screen, the control is sunk in the center console. The sinking and retracting can be realized by a mechanical coupling with the touch screen or by an active motor, which is controlled when changing the holding position of the touch screen. By sinking the control it is possible to arrange the touch screen in the same place where previously the control has been presented. As a result, the driver does not have to avert his gaze while driving in order to recognize where he has to reach with his hand in order to be able to carry out an operator action.

The holding device may be designed so that the driver himself releases the touch screen from the holding device and places it in one of the two holding positions. For this purpose, so then the touch screen is non-destructive and reversibly releasably connected to the holding device, for. B. by a snap connection or a connector. Preferably, however, it is provided that the holding device has a carriage on which the touchscreen is arranged and which is designed to move the touchscreen between the first holding position and the second holding position. This results in the advantage that the touch screen is always firmly connected to the center console and yet can be moved in the vehicle interior.

The touch screen can be manually moved by the driver between the holding positions back and forth. A further development, however, provides that the holding device is driven by means of a motor.

Here, a development provides that the holding device is designed to receive driving data of the motor vehicle, which describe a current or forthcoming driving operation of the motor vehicle, and the touch screen in dependence on the driving data in one of the two To stop positions. This results in the advantage that during a drive the touch screen can be moved to those holding positions, to which it is known that it causes a lower driver deflection. It can also be provided that the driver sets by means of a configuration device of the motor vehicle, which holding position is to be taken in the presence of predetermined driving data. As driving data, for example, the driving speed of the motor vehicle can be received. Further driving data can indicate, for example, whether an autonomous driving operation is performed by a driver assistance system or will be activated so that the driver does not drive the motor vehicle himself. got to. Further driving data may relate to a selected gear of a transmission of the motor vehicle, so that on the one hand a distinction can be made between a forward drive or an upcoming forward drive on the one hand and a reverse driving in accordance with a reverse drive on the other hand. The described driving data are given by way of example only and do not represent a complete description of the driving data. In general, all travel data receivable by the control device, for example via a communication bus of the motor vehicle, can be used. A suitable communication bus is, for example, the CAN bus of the motor vehicle (CAN - Controller Area Network).

In connection with a motorized holding device can also be provided that an operating device, such as a button, is provided, by means of which the driver pretends which holding position the touchscreen should occupy.

The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car.
