An array of control devices having a plurality of control devices (--) which are interconnected via a first data bus (), in a means of transportation, control devices (--) which are of redundant configuration with respect to a control function being provided, and in each case a data bus isolating switch () being assigned to the control devices (--) which are of redundant configuration, the data bus isolating switch(s) connecting or disconnecting the data bus () as a function of an evaluation signal. In order to optimize the redundant array, each of these data bus isolating switches () is connected to a signal line of at least one further redundant control device (--), a further redundant control device () transmits an evaluation signal to the data bus isolating switch () which is assigned to a first redundant control device ().

Redundant array of control devices

A method and a device for handling errors of software modules for redundantly designed systems in vehicles in order to optimize error handling for redundantly designed systems in vehicles, so that errors are detected and error handling measures are introduced. In addition, error handling is configured in such a way that it can be used for a plurality of software-controlled applications that run on a control device. Furthermore, a device for performing the method uses direct and/or indirect redundant input data to determine the adjusted input data for the software modules.
