Abstract: A control unit for a motor vehicle includes a central processing unit, which is configured to execute one or more control programs. The control unit has a communication interface, and a memory for storing the program data of respective control programs. The control unit evaluates a program data update request, provided at the communication interface, for a control program that is to be updated. The program data update request includes an address of an external data source, which is independent of the control unit and from which the respective current program data of the control program to be updated can be requested. The control unit outputs a program data request to the external data source, reads in the program data of the respective control programs, which are present at the communication interface in response to the program data request, and stores the program data in the program memory.

Abstract: In a motor vehicle, a driver of the vehicle can identify himself or herself. A vehicle driver signal specific to the driver of the vehicle is then generated and transmitted by the motor vehicle by way of a transmitter. This allows devices situated in the vicinity of the vehicle to respond individually to a driver of a vehicle and to supply him or her with corresponding information.

Abstract: A control unit for a motor vehicle includes a central processing unit, a communication interface and a memory for storing program data of respective control programs. For programming the control unit with program data, which are stored in a specified manner in the memory, the control unit is operatively configured for supporting a specified set of protocols and for reading-in and analyzing a program data updating prompt for a control program to be updated, which prompt is provided at the communication interface. The updating prompt includes a first indicator representing conceivable protocols usable for programming with updated program data. The control unit, as a function of the first indicator, determines a second indicator, which represents that protocol from the set usable for programming of the control unit with the updated program data. The control unit sends, in response to the program data updating prompt, a program data request, which includes the second indicator.
