14、ed v Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whic
15、h a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all ma
16、tters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circ
17、ulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held respons
18、ible for identifying any or all such patent rights. ISO 17458-5 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO 17458 consists of the following parts, under the general title Road vehicles FlexRay communications system: Part 1

20、13 All rights reserved Introduction The FlexRay communications system is an automotive focused high speed network and was developed with several main objectives which were defined beyond the capabilities of established standardized bus systems like CAN and some other proprietary bus systems. Some of
21、 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 multip
22、le 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
23、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 servi
24、ce that addresses the power management needs. This bus system has been developed with several main objectives which were defined beyond the capabilities of existing bus systems like CAN and some other proprietary bus systems. This advanced automotive communication system specifies support for: Scala
25、ble static and dynamic message transmission (deterministic and flexible); High net data rate of 5 Mbit/sec; gross data rate approximately 10 Mbit/sec; Scalable fault-tolerance (single and dual channel); Error containment on the physical layer through an independent Bus Guardian; Fault tolerant clock
26、 synchronisation (global time base). Since start of development the automotive industry world wide supported the specification development. The FlexRay communications system has been successfully implemented in production vehicles today. The ISO 17458 series specifies the use cases, the communicatio
27、n protocol and physical layer requirements of an in-vehicle communication network called “FlexRay communications system“. This part of ISO 17458 has been established in order to define the use cases for vehicle communication systems implemented on a FlexRay data link. To achieve this, it is based on
28、 the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 1 and ISO/IEC 10731 6, which structures communication systems into seven layers. When mapped on this model, the protocol and physical layer requirements specified by ISO 17458 are broken into: Diagnostic servic
29、es (layer 7), specified in ISO 14229-1 7, ISO 14229-4 9; Presentation layer (layer 6), vehicle manufacturer specific; Session layer services (layer 5), specified in ISO 14229-2 8; BS ISO 17458-5:2013ISO 17458-5:2013(E) ISO 2013 All rights reserved vii Transport layer services (layer 4), specified in
30、 ISO 10681-2 5; Network layer services (layer 3), specified in ISO 10681-2 5; Data link layer (layer 2), specified in ISO 17458-2, ISO 17458-3; Physical layer (layer 1), specified in ISO 17458-4, ISO 17458-5; in accordance with Table 1.

36、L STANDARD ISO 17458-5:2013(E) ISO 2013 All rights reserved 1 Road vehicles FlexRay communications system Part 5: Electrical physical layer conformance test specification IMPORTANT According to ISO 17458-4, the FlexRay communications system was specified focusing on a data rate of 10 Mbit/s. Therefo
37、re this conformance test specification regards the use of systems with a data rate of 10 Mbit/s only whereas the physical layer also works properly in systems with data rates in the range from 2,5 Mbit/s to 10 Mbit/s according to ISO 17458-4. 1 Scope This part of ISO 17458 specifies the conformance
38、test for the electrical physical layer of the FlexRay communications system. This part of ISO 17458 defines a test that considers ISO 9646 and ISO 17458-4. The purpose of this part of ISO 17458 is to provide a standardized way to verify whether FlexRay Bus Driver and Active Star products are complia
39、nt to ISO 17458-4. The primary motivation is to ensure a level of interoperability of FlexRay Bus Drivers and Active Stars from different sources in a system environment. This part of ISO 17458 provides all necessary technical information to ensure that test results will be identical even on differe
40、nt test systems, provided that the particular test suite and the test system are compliant to the content of this part of ISO 17458. 2 Normative references The following referenced documents are indispensable for the application of this document.
