A method for improving the reliability of the gateway system by using OSEK and duplication scheme

The gateway system is an essential component for network-to-network communication using different protocols inside a distributed system. Since reliability is an important aspect in an automotive system, here we propose a method for improving the reliability of the gateway system by using OSEK/VDX and duplication scheme. Three factors were considered for improving the reliability of the gateway. First, a high priority message must be processed first. Second, the gateway should not transmit messages to erroneous nodes that cannot receive messages by checking the accessibility of the destination node. Third, a sub-gateway should be used alternately with the main gateway when the main gateway cannot operate correctly. In this study, we developed a CAN and FlexRay gateway embedded system and applied the proposed method to this system.
