Taxonomy & Definitions for Operational Design Domain (ODD) for Driving Automation Systems

2021-07-15
WIP
J3259
Per SAE J3016 (2021), the Operational Design Domain (ODD) for a driving automation system is defined as “Operating conditions under which a given driving automation system, or feature thereof, is specifically designed to function, including, but not limited to, environmental, geographical, and time-of-day restrictions, and/or the requisite presence or absence of certain traffic or roadway characteristics.”; in short the ODD defines the limits within which the driving automation system is designed to operate, and as such, will only operate when the parameters described within the ODD are satisfied.. This information Report serves to provide terminology, definitions and taxonomy for use in describing an ODD and respective elements for a driving automation system. This classification and definition of a harmonized set of ODD elements is based on the collection and analysis of existing information from multiple sources.

High Temperature Materials for Exhaust Manifolds

1999-08-01
HISTORICAL
J2515_199908
A subcommittee within SAE ISTC Division 35 has written this report to provide automotive engineers and designers a basic understanding of the design considerations and high temperature material availability for exhaust manifold use. It is hoped that it will constitute a concise reference of the important characteristics of selected cast and wrought ferrous materials available for this application, as well as methods employed for manufacturing. The different types of manifolds used in current engine designs are discussed, along with their range of applicability. Finally, a general description of mechanical, chemical, and thermophysical properties of commonly-used alloys is provided, along with discussions on the importance of such properties.

Standard Rainflow File Format

2018-08-24
CURRENT
J2623_201808
This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum. Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history.

J2996_201301
This SAE Recommended Practice is intended for the determination of the losses of hydrocarbon fluids by permeation through small diameter fuel hose typically 4.75mm ID or less and typically used on Small Off-Road Engines (SORE) less than 19 kW as regulated under 40 CFR Part 1054.

Recommended Practice for Improving Measurement Quality of Particle Number Counting Devices

2020-08-20
CURRENT
J3160_202008
The scope of this document focuses on the setup and use of solid particle number (SPN) counting devices in both engine development and certification environments. The document reviews best practices for collecting and measuring samples from both raw and diluted exhaust gas streams across several sample probe insertion locations relative to installed aftertreatment devices. Appropriate dilution techniques, sample transfer processes, and temperature management techniques are included. Finally, performance and validation checks are covered to ensure that long-term degradation and instrument failures can be identified quickly. The particle size range targeted in this document is >23 nm, which aligns with the present EU SPN regulations and targets only solid particles. Current commonly available measurement devices are designed for counting efficiencies of 50% at 23 nm and 90% counting efficiencies at 40 nm so the contents of this document primarily address these particle sizes.

Enhanced E/E Diagnostic Test Modes

CURRENT
J2190_200810
This SAE Recommended Practice describes the implementation of Enhanced Diagnostic Test Modes, which are intended to supplement the legislated Diagnostic Test Modes defined in SAE J1979. Modes are defined for access to emission related test data beyond what is included in SAE J1979, and for non-emission related data. This document describes the data byte values for diagnostic messages transmitted between diagnostic test equipment, either on-vehicle or off-vehicle, and vehicle electronic control modules. No distinction is made between test modes for emission related and non-emission related diagnostics. These messages can be used with a diagnostic serial data link such as described in SAE J1850 or ISO 9141-2. For each test mode, this document includes a functional description of the test mode, request and report message data byte content, and an example if useful for clarification.

Hydrogen Vehicle Crash Test Lab Safety Guidelines

2022-02-23
CURRENT
J3121_202202
The scope of this document is to provide an overview of the risks and protective precautions to ensure safe and effective testing procedures for the test personnel and the vehicle during the testing of a hydrogen fuel cell vehicle. The main risks associated with a hydrogen fuel cell vehicle are the fuel cell stack, hydrogen storage vessel, fuel cell system components and the high voltage battery. Risks could be summarized from the battery into thermal runaway possibly leading to fire or explosion, electrolyte spillage and electrical shock or electrocution. The hydrogen fuel cell system risks include electrical shock or electrocution and possible release of hydrogen gas (if tested with). Vehicle crash testing protection should be coordinated with the system or component manufacturer(s) suggestions. Precautions should be taken with the handling, transportation, and storage of the vehicle pre-crash and post-crash.
