    5、 Revised 2012-11 Superseding J2602-1 SEP2005 LIN Network for Vehicle Applications RATIONALE The LIN protocol is a low speed low cost communication protocol that is capable of reducing wire counts to simple devices like switches and sensors. This document defines an implementation of the LIN protocol

    6、 with the focus on enabling ASIC designs commonly found in switches and sensors. FOREWORD The objective of this document is to define a level of standardization in the implementation of low speed vehicle serial data network communications using the Local Interconnect Network (LIN) protocol. The goal

    7、 of this document is to define a serial data physical layer, data link layer and media design criteria to be installed in various automotive Electronic Control Units (ECU). This standard will allow ECU and tool manufacturers to satisfy the needs of multiple end users with minimum modifications to th

    8、e basic design. This standard will benefit vehicle Original Equipment Manufacturers (OEMs) by achieving lower ECU costs due to higher industry volumes of the basic design. NOTE: Understanding of this document requires a working knowledge of the LIN 2.0 Specification Package. TABLE OF CONTENTS 1. SCO

SCOPE This document covers the requirements for SAE implementations based on LIN 2.0. Requirements stated in this document will provide a minimum

    19、 standard level of performance to which all compatible ECUs and media shall be designed. This will assure full serial data communication among all connected devices regardless of supplier. The goal of SAE J2602-1 is to improve the interoperability and interchangeability of LIN devices within a netwo

    20、rk by resolving those LIN 2.0 requirements that are ambiguous, conflicting, or optional. Moreover, SAE J2602-1 provides additional requirements that are not present in LIN 2.0 (e.g., fault tolerant operation, network topology, etc.). This document is to be referenced by the particular vehicle OEM co

    21、mponent technical specification that describes any given ECU in which the single wire data link controller and physical layer interface is located. Primarily, the performance of the physical layer is specified in this document. ECU environmental and other requirements, when provided in the component

    22、 technical specification, shall supersede the requirements of this document. The intended audience includes, but is not limited to, ECU suppliers, LIN controller suppliers, LIN transceiver suppliers, component release engineers and vehicle system engineers. 1.1 Mission/Theme This serial data link ne

    23、twork is intended for use in applications where high data rate is not required and a lower data rate can achieve cost reductions in both the physical media components and in the microprocessor and/or dedicated logic devices (ASICs) which use the network. 1.2 Overview LIN is a single wire, low cost,

    24、Class A communication protocol. LIN is a master-slave protocol, and utilizes the basic functionality of most Universal Asynchronous Receiver Transmitter (UART) or Serial Communication Interface (SCI) devices as the protocol controllers in both Master and Slave devices. To meet the target of “Lower c

    25、ost than either an OEM proprietary communications link or CAN link” for low speed data transfer requirements, a single wire transmission media based on the ISO 9141 specification was chosen. The protocol is implemented around a UART/SCI capability set, because the silicon footprint is small (lower c

    26、ost). Many small microprocessors are equipped with either a UART or SCI interface (lower cost), and the software interface to these devices is relatively simple to implement (lower software cost). Finally, the relatively simplistic nature of the protocol controller (UART/SCI) and the nature of state

    27、-based operation, enable the creation of Application Specific Integrated Circuits (ASICs) to perform as input sensor gathering and actuator output controlling devices, in the vein of Mechatronics. All message traffic on the bus is initiated by the Master device. Slave devices receive commands and re

    28、spond to requests from the Master. Since the Master initiates all bus traffic, it follows that the Slaves cannot communicate unless requested by the Master. However, Slave devices can generate a bus wakeup, if their inherent functionality requires this feature. SAE J2602-1 Revised NOV2012 Page 4 of

    29、48 The “LIN Consortium” developed the set of LIN specifications. The Consortium is a group of automotive OEMs, semiconductor manufacturers, and communication software and tool developers. The LIN specification set is “released” by the LIN Steering Committee, a closed subset of the members. Associate

    30、 Consortium members contribute to the formation of the specifications through participation in LIN Work Groups; however, the direction of the Work Groups and the final released content of the specifications is the responsibility of the LIN Steering Committee. The LIN Specifications contain more than

    31、 just a definition of the LIN protocol and physical layer. In addition, a Work Flow Process, Diagnostics and Configuration methods, definition of an Application Program Interface (API), file structures for a Node Capability File (NCF) and a LIN Description File (LDF) and semantics are identified as

    32、required (mandatory in all implementations). However, since there is a great deal of flexibility in the protocol and physical layer, applicability of these specifications to J2602-1 networks will be further specified in this document. 1.3 Relationship to the LIN Specifications As described in the LI

    33、N Specification Package, the LIN 2.0 protocol specification suite consists of seven documents: 1.3.1 LIN Specification Package The LIN Specification Package provides an overview of the LIN Protocol, its features, and work flow. This includes the Revision History, LIN Overview and Glossary. 1.3.2 LIN

    34、 Physical Layer Specification The LIN Physical Layer Specification describes the physical layer, including bit rate, clock tolerances, etc. 1.3.3 LIN Protocol Specification The LIN Protocol Specification describes the data link layer of LIN. 1.3.4 LIN Diagnostic and Configuration Specification The L

    35、IN Diagnostic and Configuration Specification describe the services that can/may be layered on top of the data link layer to provide for diagnostic messages and node configuration. 1.3.5 LIN API Specification The LIN API Specification describes the interface between the network and the application p

    36、rogram, including the diagnostic module. 1.3.6 LIN Configuration Language Specification The LIN Configuration Language Specification describes the format of the LIN description file, which is used to configure the complete network and serve as a common interface between the OEM and the suppliers of

    37、the different network nodes, as well as an input to development and analysis tools. 1.3.7 LIN Node Capability Language Specification The LIN Node Capability Language Specification describes a format used to describe off-the-shelf slave nodes that can be used with a system definition tool to automati

    38、cally create LIN Description Files. The remainder of this document (SAE J2602-1) will directly reference these LIN specifications. SAE J2602-1 Revised NOV2012 Page 5 of 48 2.
