摘要： The invention relates to a control unit arrangement comprising a plurality of control units (1-3, 20-23) in a means of transport, said control units being networked by means of a first data bus (4). Said arrangement contains control units (1-3; 20-3) which are redundant in terms of a control function and a data bus disconnector (5) is associated with the redundantly embodied control units (1-- 3; 20-23), said disconnector connecting or disconnecting the data bus (4) according to an evaluation signal. In order to optimise the redundant arrangement, each of said data bus connectors (5) is connected to a signal line of at least one other redundant control unit (1-3; 20-23), another redundant control unit (2,3; 21; 23) transmits an evaluation signal to the data bus disconnector (5) associated with a first redundant control unit (1; 20; 22), the evaluation signal being the result of a functional test of the other redundant control unit (2,3; 21; 3) in terms of the first redundant control unit (1; 20; 22). The data bus disconnector (5) of the first redundant control unit (1; 20; 22) disconnects the data bus (4) according to the result of a logic circuit, at least one input signal of the logic circuit being formed by the at least one evaluation signal.

摘要： Disclosed is a redundant data bus system comprising two data buses (B1, B2) between which at least two error-protected control devices (26 to 32) are connected. Both data buses (B1, B2) operate with the same data bus protocol (FlexRay, CAN) at substantially the same transmission frequency while safety-relevant control messages are transmitted in parallel via both data buses (B1, B2) and are processed in the control devices (26 to 32). Each of the control devices (26 to 32) has its own control task which is executed via an associated control software. Two independently operating microcomputers (µR) which encompass the control software of both the first and the second control task are provided in each control device (26 to 32) such that the control task can be taken over by the other control device when one control device (23 to 32) breaks down. One respective data interface (34) via which the result data calculated from the safety-relevant control messages can be exchanged and compared to each other is located between the two microcomputers (µR) in the control device. Furthermore, a deciding means (33) is provided which decides, based on the comparison of the result data, which microcomputer (µR) or which control device (26 to 32) is to perform a control task.
