scope:

The FlexRay communications system is an automotive focused high speed network. Some of the basic characteristics of the FlexRay protocol are synchronous and asynchronous frame transfer, guaranteed frame latency and jitter during synchronous transfer, prioritization of frames during asynchronous transfer, single or multi-master clock synchronization, time synchronization across multiple networks, error detection and signalling, and scalable fault tolerance. The FlexRay communications system is defined for advanced automotive control applications. It serves as a communication infrastructure for future generation high-speed control applications in vehicles by providing: - A message exchange service that provides deterministic cycle based message transport; - Synchronization service that provides a common time base to all nodes; - Start-up service that provides an autonomous start-up procedure; - Error management service that provides error handling and error signalling; - Wakeup service that addresses the power management needs; This part of ISO 17458 gives an overview of the structure and the partitioning of ISO 17458 and shows the relation between the different parts. In addition, it outlines the use case scenarios where the ISO 17458 document set will be used. The terminology defined in this part of ISO 17458 is common for all FlexRay communication systems and is used throughout all parts of ISO 17458.
