A method for operating a communications network that includes a computing system, at least one intermediate control unit, and at least one execution unit for each intermediate control unit. The at least one intermediate control unit is communicatively connected to the computing system using a first communication system. Each of the at least one execution unit is communicatively connected to the associated intermediate control unit using a second communication system, which is a master-slave communication system, and used as a slave. A message configuration table for each second communication system is stored in the computing system, the message configuration table indicating a temporal sequence of data to be transmitted on the second communication system in question. For a communication with one of the execution units, data are sent from the computing system, via the associated intermediate control unit, to the execution unit according to the associated message configuration table.

A method for operating a vehicle electrical system of a vehicle, configured in an architecture in which at least one central vehicle computer is assigned to a computational layer, intermediate control devices are assigned to an intermediate layer, and execution units are assigned to an execution layer. The at least one central vehicle computer contains datasets of at least the intermediate control devices linked to the relevant central vehicle computer. Each dataset interfaces are described for all execution units which are connected communicatively indirectly or directly via the second communication system with the relevant intermediate control device. In each central vehicle computer, an intermediate application is executed via which, using a relevant dataset, access is configured of applications executed on the relevant central vehicle computer via the relevant intermediate control device to execution units linked thereto.

A computing device that includes a first processing unit and a second processing unit that are connected to one another in a data-transmitting manner. The first processing unit, upon recognition that an activation condition is present, is configured to determine whether the activation condition requires an activation of the second processing unit, and when the activation condition requires the activation of the second processing unit, to activate the second processing unit and to output an activation signal, including the activation condition, on an activation line. Also, a network that includes at least two such computing devices, and a method for activating a second processing unit of a computing device that includes a first processing unit and the second processing unit, which are connected to one another in a data-transmitting manner, are also described.

A method for operating a communications network that includes at least two users that are communicatively connected to one another via a descriptor-based communication system such as Ethernet. For writing data from a writing user into a user to be written, receive descriptors and data are transmitted from the writing user to the user to be written, in the user to be written, the data being written according to the received receive descriptors, and/or for reading data by a reading user from a user to be read, transmit descriptors are transmitted from the reading user to the user to be read, data being read by the user to be read according to the received transmit descriptors and transmitted to the reading user. A communications network and users are also described.

A method and device for monitoring a bus system and bus system having at least two users, of which at least one is structured as an authorized user and monitors the data transmission on the bus system, an identifier being transmitted and the identifier being uniquely allocatable to one user for each data transmission on the bus system, the at least one authorized user comparing the identifier with a specified identifier, and if both identifiers are the same taking measures in order to prevent an execution of the data to be transmitted if the data transmission is initiated by a user other than the at least one authorized user.

A device for reliably generating signals in a motor vehicle, having a control arrangement which is supplied at least one control signal, the control arrangement generating a trigger signal as a function of the control signal in order to trigger at least one switching element or driver. The control arrangement includes an emergency-operating arrangement which, in an emergency operation, generates the trigger signal as a function of at least the one control signal, a testing arrangement being provided, which tests the operativeness of the emergency-operating arrangement by selective triggering.

A method and device is described for transmitting information on a bus system having at least two users, as well as a bus system, exactly one superordinate user (master) and at least one subordinate user (slave) being provided, and the information being transmitted in a definable, closed message frame which, in addition to the information to be transmitted, also contains synchronization information, different information being uniquely assigned different information identifiers; after each closed message frame, a number of information sections being provided in which the at least one subordinate user may enter information.

For a closed-loop feedback control of a controlled system having a predetermined set course and a control trajectory for use in controlled systems in motor vehicles, an output trajectory of the controlled system is measured for the entire control time in which the control trajectory is applied to the controlled system, an error of the controlled system is detected as a function of predetermined set course and the output trajectory, and a new control trajectory is calculated for each instant of a later control process as a function of the error and the control trajectory.
