摘要： The present disclosure relates to a method for controlling a low-consumption mode of an electronic switching unit, which is supplied with an electrical operating current via a current path, wherein a circuit-external power control unit transmits an activation command for activating the low-consumption mode to the switching unit. A measuring device for generating a consumption signal that is a function of an amperage of the operating current being operated in the current path is disclosed. After the activation command has been transmitted the power control unit uses the consumption signal to determine whether the amperage is still above a threshold value that is specified for the low-consumption mode, and in this case a predetermined emergency measure is initiated to force the low-consumption mode and/or to reduce the amperage.

摘要： The invention relates to a process for operating an infotainment system with the following steps. In a first step, the infotainment system is operated in a first operating state. In a second step, the infotainment system is operated in a first energy-saving state. In a third step, a timer is provided for waking up an operating state management mechanism of the infotainment system at a wake-up time. In a fourth step, the infotainment system is placed in a second energy-saving state. In a fifth step, the operating state management mechanism of the infotainment system is woken at a wake-up time by means of a timer. In a sixth step, the infotainment system is operated in the first energy-saving state.

摘要： A data-processing device includes a computing unit and an interface unit using a packet-based communication protocol, in particular PCI Express. The data-processing device also includes an intrusion detection unit that is connected via a signal connection to a filter device of the interface unit, and/or to a secure element, in the form of a Trusted Execution Environment, of an authentication arrangement related to the communication protocol. The intrusion detection unit evaluates input signals received via the signal connection for a rule infringement in a set of intrusion detection rules The filter device, at least part of which is hardware, is designed to forward only the communication data meeting an approval condition from the interface unit to an additional component of the data-processing device according to configuration information predetermined in the data-processing device and containing the approval condition. At least one intrusion detection rule relates to the infringement of the approval condition and/or to an authentication error.

摘要： The disclosure relates to a control apparatus for enabling functions, comprising an integrated circuit. The control apparatus has a function register unit for storing at least one entry relating to an enabled state of a respective circuit function and/or of a respective circuit area of the integrated circuit. The integrated circuit is configured to enable the respective circuit function and/or the respective circuit area for use in accordance with the at least one entry in the function register unit. The control apparatus has a function control unit configured to respond to a predetermined actuation signal by changing the at least one entry in the function register unit, wherein the change is made only if a predetermined authenticity check based on a cryptographic method confirms a source of the actuation signal is authorized, so that the function control unit is actuatable only by a trusted source.

摘要： A device for providing image data of an image to be output on a display apparatus in a motor vehicle. The device having an integrated circuit, which includes a computing unit as a component in a first circuit section and a superimposition unit as a component in a second circuit section. The computing unit determines first partial image data relating exclusively to a portion of the image that is safety-relevant. The superimposition unit superimposes second partial image data that are not safety-relevant onto the first partial image data in such a way that the image data in the entire portion of the image, or in regions of the portion for which the first partial image data are not transparent, are predefined by the first partial image data.

摘要： The invention relates to a control unit for a motor vehicle, wherein the control unit is configured to switch off, upon reception of an ignition-off signal transmitted in the motor vehicle for initiating a parked phase, a main module provided for operation with ignition switched on. It is the object of the invention to provide a remote service with low latency during the parked phase. For this purpose, in the control unit, a mobile radio module is provided, which is configured so that it remains logged into a mobile radio network with the main module switched off. An auxiliary processor device is configured to reserve an Internet address on an address server of the Internet via the mobile radio module, and to store the Internet address on a control server of the Internet, which is configured for the remote control of the motor vehicle.

摘要： 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.
