    11、ember bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governm

    12、ental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Dir

    13、ectives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

    15、mittee SC 3, Electrical and electronic equipment. ISO 10681 consists of the following parts, under the general title Road vehicles Communication on FlexRay: Part 1: General information and use case definition Part 2: Communication layer services BS ISO 10681-1:2010ISO 10681-1:2010(E) iv ISO 2010 All

    16、 rights reservedIntroduction This part of ISO 10681 is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498 and ISO/IEC 10731, which structures communication systems into seven layers (see example in Table 1). When mapped on this model, ISO 10681 incorporat

    17、es the network layer (layer 3) and the transport layer (layer 4) services as communication layer services. The ISO 10681 document set provides an implementer with all documents and references required to support the communication implementation on FlexRay networks. ISO 10681-1: General information a

    18、nd use case definition (this part), provides an overview of the document set along with the use case definitions and a common set of resources (definitions, references) for use by all subsequent parts. ISO 10681-2: Communication layer services specifies a communication protocol to meet the requireme

    19、nts of FlexRay-based vehicle network systems as specified in the FlexRay Communications Systems Protocol Specification. NOTE Additional parts of ISO 10681 will be introduced as necessary.

    26、 case 1: Multipurpose communication layer The communication layer shall be able to handle various message transmission types such as Diagnostics, Multi Media or Inter ECU communication. However, usage purposes are not limited to the ones stated above. BS ISO 10681-1:2010ISO 10681-1:2010(E) 2 ISO 201

    27、0 All rights reserveda) Transmit messages with known data length: Message transmission where the length of the transmitted message is known by the application. This kind of feature applies to most known applications (e.g. ECU programming, diagnostics, etc.). b) Transmit messages with unknown but fin

    28、ite data length: The final message length is unknown at start of message transmission. However, the data shall be finite in order to keep the transport layer implementation manageable. The feature might be used for any data streaming applications. c) Additional acknowledgement with retry mechanism:

    29、A message transmission is acknowledged (positive / negative) once it is completed. In addition, a retry mechanism might be supported, where the message transmission is being repeated at the detected first wrong byte position. This feature might be used for, e.g., Inter ECU communication mechanism. d

    30、) Routing data on the fly: Gateway mechanism, where the data are already transmitted onto the target subnet, while it is still in the process of being received on the source subnet. e) Support of dynamic frame length: Variable payload length (PDU_Size) in a single FlexRay frame, e.g. for optimized g

    31、ateway handling in regard of buffer requirements. Possible applications could be “routing data on the fly” or “data streaming”. 4.2.2 Use case 2: Optimize flash programming time a) Flexible bandwidth usage: Achieve optimized message transmission independent of the given network bandwidth assignment.

    32、 b) Support of parallel diagnostic communication: The communication layer shall be capable to support concurrent ECU programming events. 4.2.3 Use case 3: Optimize gateway implementations a) Routing data on the fly: See d) in use case 1 (4.2.1). b) Receive and forward: Allow to transfer a message fr

    33、om a given network onto FlexRay (and vice versa) without re-mapping payload information of a frame, where only the PCI information needs to be adapted. c) Optimize addressing scheme: See d) in use case 1 (4.2.1). 4.2.4 Use case 4: Communication layer definition The communication layer definition sha
