Abstract: A method of operating an information system of a vehicle, in which a processor subsystem of a system on a chip (SoC) of the information system of the vehicle executes a system partition of the SoC and a vehicle infotainment partition (IVI) of the SoC. A functional system of the system partition produces a graphical operating element and locates the graphical operating element in a composition plane of a main compositor of the information system, which plane is at the front relative to a user's sight line. A touch-sensitive display screen which is functionally connected to the SoC is arranged centrally in the vehicle to display a display content which is provided by the main compositor and includes the graphical operating element. The described examples relate to an information system for a vehicle.
