In modern motor vehicles, touch-sensitive display elements or touch-sensitive screens, so-called touch screens or multi-touch screens, are increasingly being used as operating devices. Touchscreens are combined input and output devices in which electronic components can be controlled by touching the screen. Thus, the automotive electronics, for example a navigation system or multimedia systems of the motor vehicle, can be controlled by means of these touch-sensitive display elements. In this case, an occupant of the motor vehicle, for example, select a transmitter for the car radio from a station list, which is displayed in the menu of the car radio on the touch-sensitive display element by the occupant touches the transmitter displayed with his finger.

If the occupant wishes to operate another electronic component of the motor vehicle, for example an air conditioning system, then he usually has to leave the menu in which the touch-sensitive display element is currently located, for example the menu of the car radio. He then has to open a new menu, for example the menu of the air conditioner, and set the desired function there. Such an elaborate menu navigation can distract the occupants, especially the driver, considerably from the driving, since he has to direct his view of the display element for operation with a possible menu change.

To work around this problem, the DE 697 10 815 T2 to arrange a tactile surface for the recognition of symbols in the vehicle so that the contact of the hands of the driver with the steering wheel is maintained. A tactile surface, which recognizes in particular manuscripts, is also from the GB 2 355 055 A known.

A touch-sensitive display element or a touch-sensitive screen may be, for example, a so-called touch screen or a multi-touch screen, which may be arranged in a center console of the motor vehicle. A touch screen is a combined input and output device that can, for example, display data on the screen and capture operator input by a user. The touch-sensitive display element according to the invention can communicate with a first electronic component via a first interface. The first electronic component can be, for example, a control unit of a navigation system and / or a car radio. In this case, data concerning the first electronic component can be displayed on the touch-sensitive display element. Such data may be, for example, a map or a digital map or a station list of the car radio. The data displayed on the screen can also be changed or selected via operating inputs of a user, for example the driver.

It is provided to provide on the touch-sensitive display element, a second interface for communication with an input recognition device which detects or recognizes a character entered by a user. The input recognition device compares the input character with predetermined characters or reference characters, which can be stored, for example, in a database. If the input character matches a reference character assigned to the second electronic component, the input recognition device activates the second electronic component. The second electronic component may be, for example, a seat heater.

The peculiarity of the invention is that by the input of the character, which is assigned to the second electronic component, both the display of the data of the first electronic component as well as the communication with the first electronic component unaffected or unchanged. This means that the user on the touch-sensitive display element can make an input for the second electronic component, although the data on the first electronic component are displayed on the touch-sensitive display element at the time of user input. In other words, this means that the user can simply swipe, for example with his finger, over the displayed data on the touch-sensitive screen, for example the digital map, so as to paint or write an input character on the surface of the touch-sensitive screen. The input recognition device or gesture recognition device recognizes by a comparison with a predetermined character that the user wants to address the second electronic component, and then controls the second electronic component.
