Description / Abstract:
1. Scope--This SAE Recommended Practice will define the Physical Layer
and portions of the Data Link Layer of the ISO model for a 500 KBPS
High-Speed CAN (HSC) protocol implementation. Both ECU and media design
requirements for networks will be specified. Requirements will
primarily address the CAN physical layer implementation.
Requirements will focus on a minimum standard level of performance from
the High-Speed CAN (HSC) implementation. All ECUs and media shall be
designed to meet certain component level requirements in order to
ensure the HSC implementation system level performance at 50 KBPS. The
minimum performance level shall be specified by system level
performance requirements or characteristics described in detail in
Section 6 of this document.
This document is designed such that if the Electronic Control Unit
requirements defined in Section 6 are met, then the system level
attributes should be obtainable.
This document will address only requirements which may be tested at the
ECU and media level. No requirements which apply to the testing of the
HSC implementation as integrated into a vehicle are contained in this
document. However, compliance with all ECU and media requirements will
increase the possibility of communication compatibility between
separately procured components and will greatly simplify the task of
successfully integrating a HSC communication system in a vehicle.
