Abstract: An approach for operating at least one touch-sensitive, flat input device of a complete device, the input device being connected via a message-based bus connection to a control device of the complete device, and messages containing touch datasets describing touch data events being transmitted to the control device, which evaluates the messages for input information for an application program implemented by the control device, wherein when a security function in the control device that queries sensitive input information is accessed, the touch datasets are transmitted from the input device to the control apparatus via the bus connection in encrypted form until the associated input process has ended.

Abstract: A number of objects simultaneously touching a touch-sensitive operator control unit of an operator control apparatus are detected and a trigger position at which one of the number of objects detected touches the touch-sensitive operator control unit is determined. When more than one object touches the touch-sensitive operator control unit, a touch pressure with which the touch-sensitive operator control unit is acted on overall by the number of objects detected is compared to a predefined pressure threshold value. A function of the motor vehicle, assigned to the trigger position, is triggered if the touch pressure is higher than the predefined pressure threshold value. The predefined pressure threshold value is defined in a manner dependent on the number of objects detected.

Abstract: A touchpad detects a duration of a touch by an object at a current position and/or a distance traversed by the object. An operator control mode is predefined as a function of the duration and/or the distance. A pressure threshold value is predefined as a function of the operator control mode. The pressure applied to the touchpad is detected and if higher than the predefined pressure threshold value, a function of the motor vehicle which is assigned to the current position is triggered.

Abstract: A detection device detects a position at which a touch-sensitive operator control unit is touched by an object by detecting a pressure (pm) which is applied to the touch-sensitive operator control unit by the object at the position. In addition, a speed (vm) and/or an acceleration (am) of the motor vehicle is detected and a pressure threshold value (ps) is predefined as a function of speed (vm) and/or accelerations (am) of the motor vehicle. The method determines whether the detected pressure (pm) is higher than the predefined pressure threshold value (ps) and triggers a function (F), assigned to the detected position, of the motor vehicle exclusively if the detected pressure (pm) is higher than the predefined pressure threshold value (ps).
