    摘要: A method and a device for transmitting information in a network having at least three subscribers, as well as a corresponding network, the information being transmitted in at least a first frame of a predefined length and structure, and the first frame on a first transmission path being transmitted in a loop to the next, second subscriber in each instance, given a predefined transmission direction, the information being additionally transmitted in a second frame having the same length and structure as the first frame, the second frame on a second transmission path being transmitted to a one-after-the-next, third subscriber, the second transmission path and, thus, the second frame skipping the second subscriber, and an assessment being made in dependence upon at least one criterion, thus information, length or structure.

    摘要: A method for transmitting data, in which a first signature is formed according to a specifiable signature formation method as a function of the data to be transmitted, the first signature is transmitted together with the data a second signature is formed according to the signature formation method as a function of the transmitted data and the first signature is compared with the second signature. To reduce the likelihood of fault masking in monitoring the transmission of the data using signature analysis, a provision is made to invert the data to be transmitted, to form the first signature according to the specifiable signature formation method as a function of the data to be transmitted and of the inverted Data, to transmit the first signature and the data to invert the transmitted data, to form the second signature according to the signature formation method as a function of these inverted data and the transmitted data, and to compare the first signature with the second signature.

    摘要: A vehicle-supported data processing system includes a plurality of processing units communicating with one another via a bus system, which are each supplied with operating power by at least one of the at least two different vehicle electrical systems. Multiple transmitter units for control information and multiple receiver units for the control information are among the processing units. The bus system is a ring bus, in which each processing unit is connected to at least two adjacent processing units by a bus segment in each case. The ring bus is divided, by potential separating devices, which are incorporated in the bus segments which connect processing units powered by different vehicle electrical systems, into a number of sections, which is smaller than the number of the processing units.
