Abstract: A method for monitoring a data network in a motor vehicle is provided, wherein a switch device is operated in the data network, in which physical ports for receiving and for transmitting data packets are interconnected via a switch circuit. A network processor reads out detection data in monitoring positions of the data packets and forms pseudo target determination data for an associative memory therefrom, which actually is to process target determination data for a target port determination, and it is examined if certain action data results, which signalizes a necessity of a detection action, by inputting the pseudo target determination data into the associative memory.

Abstract: A method and a fault-tolerant computer architecture (FCTA) for fail-safe trajectory planning for a moving entity (MOV). The method and FCTA uses a commander (COM), a monitor (MON), and a safe envelope generating stage (ENV). Based on sensor input, the commander (COM) and the monitor (MON) produce real-time images of objects (OBJ1, OBJ2) detected. A trajectory planning stage (TRJ-PLN) generates trajectories (COM-TRJ1, COM-TRJ2), and the safe envelope generating stage (ENV) generates a safety envelope. The commander (COM) provides the one or more trajectories (COM-TRJ1, COM-TRJ2) to the monitor (MON) and the decision subsystem (DECIDE). A trajectory verification stage (TRJ-VRFY) verifies a trajectory (COM-TRJ1, COM-TRJ2) generated by the commander (COM) only if said trajectory (COM-TRJ1, COM-TRJ2) is completely located inside said safety envelope. A moving entity (MOV) uses a trajectory (COM-TRJ1, COM-TRJ2) generated by the commander (COM) only when said trajectory is verified by the monitor (MON).
