The present disclosure relates to a control device for redundant execution of an operating function, wherein the control device comprises at least a first processor unit and a second processor unit and a plurality of peripheral units and a first switching unit is provided for the first processor unit and a second switching unit is provided for the second processor unit, and wherein the control device is designed in a first operating mode to execute the operating function by means of the first processor unit and in the meantime to execute a predetermined auxiliary function by means of the second processor unit. According to the invention, the control device is designed, in a second operating mode to execute the operating function by means of the second processor unit, and in so doing to continue to execute the auxiliary function () in a predefined reduced scope by means of the second processor unit, wherein a coupling device is provided, which is designed to connect the second processor unit to the first switching unit.

The approach relates to a modular computer architecture of a cockpit and infotainment system for a vehicle that includes an I/O module with an I/O computing node () with at least one data memory, the I/O computing node being designed for processing audio data and as a host computer for performing host functions with ASIL safety requirements. The I/O module also includes a tuner with associated antenna interface, and at least one interface of a vehicle bus system. The modular computer architecture further includes at least one computing module with a computing node with at least one data memory for performing cockpit and infotainment functions, and at least one display interface.

The application relates to a method for checking the data transport across a first communication connection between two data processing devices, said first communication connection being realized between two first interface units, wherein the payload to be transferred can be divided into payload blocks and there is at least one second communication connection between the data processing devices, which is established by means of second interface units, and wherein, in order to implement a challenge-response authentication, a request requiring retrieval of randomly selected data units from identifiable, randomly selected payload blocks of the payload is sent as a challenge by an authentication unit to the first interface units by means of the second communication connection, an authentication assembly of each of the first interface units extracts the requested response data from the payload and transmits the same back to the authentication unit and a successful check is determined if the response data match.

The invention relates to a method for operating a control unit of a motor vehicle during a parked phase. It is the object of the invention to achieve an economical operation during the parked phase and in so doing to perform the service routine. For this purpose, the power supply sets a timer of a clock in the parked phase and then switches itself off. The timer generates a wake-up signal as a function of a current time indication determined by the clock, and a wake-up device of the power supply switches the power supply on again as a function of the wake-up signal. The power supply that has been switched on again then electrically connects the monitoring unit to the on-board network.
