Description / Abstract:
This document covers the requirements for SAE implementations
based on LIN 2.0. Requirements stated in this document will provide
a minimum 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 network 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
component 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 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.
