[0020] According to another aspect, the invention is characterized by a vehicle comprising the system described above for operating a touch-sensitive control display of a vehicle during a journey with the vehicle.

[0021] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. All features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are usable not only in the combinations specified, but also in other combinations or individually.

[0022] A preferred embodiment of the invention is described below with reference to the accompanying drawings. Further details, preferred configurations, and further developments of the invention will be derived from these drawings. Specifically, the drawings schematically illustrate... Fig. 1. An exemplary method for operating a touch-sensitive control display of a vehicle while driving the vehicle, and Fig. 2 An example of an operating display during a journey with the vehicle.

[0023] In detail, it shows Fig. 1 An exemplary method 100 for operating a touch-sensitive control display of a vehicle while the vehicle is in motion. The touch-sensitive control display can provide various controls, for example, media control controls and / or climate control controls, which can be operated by a vehicle occupant, for example, the driver and / or a passenger. Furthermore, a navigation function of the vehicle can be active while the vehicle is in motion. During a navigation event, a navigation control can at least partially overlay one or more controls displayed on the touch-sensitive control display.

[0024] Method 100 can detect the approach of a hand to the vehicle's touchscreen control panel using an interior camera of the vehicle 102. Furthermore, Method 100 can adjust the display of information on the touchscreen control panel during the detected approach of the hand to the vehicle's touchscreen control panel 104. The displayed information could, for example, be information about a navigation event, which can be displayed using a control element on the touchscreen control panel.

[0025] For example, the method can detect, using an interior camera, a passenger's hand approaching the vehicle's touchscreen while driving. The vehicle's navigation function is active. As the passenger's hand approaches, a navigation event occurs, which attempts to display information, such as a turn instruction, on the vehicle's touchscreen. Method 100 can suppress the display of the information, such as the turn instruction, if the passenger's hand approach is detected. If the passenger's hand approach is detected by the interior camera and the information is a navigation instruction, the method can assume that the navigation information is not intended for the passenger.In this example, the information is suppressed for the duration of the passenger's hand operation. Additionally, the information can be moved to a display visible to the driver.

[0026] Additionally, the method 100 can detect an operating movement and its direction by sensing the approach of the hand. The touch-sensitive operating display can suppress any changes to information in a predefined area in the direction of the hand during the detected approach. Changes to information can include content changes and / or layout changes. Furthermore, the method can temporarily store changes to information during the detected approach of the hand and apply them with a time delay after the hand has performed an operating action.

[0027] In detail, it shows Fig.2 An exemplary control display 200 during a journey in a vehicle. At one point in time, a touch-sensitive control display 202 shows three controls 204 for controlling media content. An interior camera can detect a hand 206 approaching the touch-sensitive control display 202. Information about the navigation event is suppressed and not displayed on the touch-sensitive control display 202. At a second point in time, the touch-sensitive control display 202 can show three controls 204 for controlling media content and information about a navigation event 208. The hand 206 has performed a control action and moves away from the touch-sensitive control display 202 again. The information about a navigation event 208 is displayed.

[0028] Advantageously, this method can efficiently prevent incorrect operation of controls on the vehicle's touch-sensitive control display 202 while driving. During a period of less than 500 milliseconds when a hand is near the touch-sensitive control display 202, for example, the method can suppress the display of information. Manual operation can then be carried out reliably.
