This recommended practice will define a reference high-level architecture for precise positioning system of passenger vehicles for V2X applications, with the goal of delivering submeter positioning accuracy performance as much as possible. The architecture will comprise GNSS (aka GPS) and IMU (Inertial Measurement Unit) with the options for including other sensors, such as wheel encoders, camera, lidar, as well as maps. The positioning system is intended to estimate absolute position, course angle, and speed of the vehicle in a global coordinate system. This document will also offer implementation recommendations.
This recommended practice will specify the review, testing, and analysis steps for certifying the performance of precise positioning system of passenger vehicles. The goal of the certification is to validate that the positioning system delivers the level(s) of performance that it claims. The levels of performance may include position accuracy at different confidence levels and integrity metrics such as protection level, risk level, and alert limit.
This document describes the megawatt-level DC charging system requirements for couplers/inlets, cables, cooling, communication and interoperability. The intended application is for commercial vehicles with larger battery packs requiring higher charging rates for moderate dwell time. A simplified analog safety signaling approach is used for connection-detection to guarantee de-energized state for unmated couplers with superimposed high speed data for EVSE-EV charging control and other value added services.
Where possible, this SAE Information Report (IR) provides current technical, real world data of automotive fluids in US market road vehicles. Any chemicals listed in safety data sheets (SDS) for automotive fluids were initially compared to at least three chemicals detected in stormwater. However, these three initial chemicals are also associated with multiple industrial & consumer activities, and possible other sources were noted & preliminary identified and/or investigated. The three initial chemicals identified are: • BPA, CAS 80-05-7 • Naphthalene, CAS 91-20-3 • Poloxalene (aka polyethylene-polypropylene glycol), CAS 9003-11-6 Based upon the development of this IR, a separate but concurrent research project was jointly proposed to provide technical data where possible, but not initiated at this time by SAE & the SAE TF using the SAE Cooperative Research Program (CRP). See Appendix A.
This specification sheet establishes requirements for a low collapse pressure configuration filter element of a specific configuration with a minimum filtration ratio of 75 for particles larger than ? μm when designed and tested in accordance with SAE J2321 and this specification sheet. Note: The efficiency and dirt capacity have not yet been determined..
The purpose of this AIR is to provide a comprehensive description document that displays various examples of low pressure seals and wipers utilized within mechanical and electromechanical actuators. The document is intended as an overview for those specifying or designing actuators in order to compare existing solutions as reference for implementation.
Recommendation Guidelines and Practices for the Design and Validation of EHA Thermal Management Considerations, particularly for Low Temperature Operation.
This recommended practice will provide guidance on the requirements of a V2X application to enable drivers (human or machine) to exchange courteous messages to resolve traffic related misunderstandings, conflicts and to minimize anxieties. Such system can lead to improving traffic safety. The related initial work in the field of driver-to-driver communication have been conducted and the research result have been published. The focus of this recommended practice is on use case definitions, information exchanges among the road users such as among multiple vehicles, or between a vehicle and a pedestrian. This effort may result in identifying new messages, data frames and data elements in SAE J2735
This SAE Recommended Practice SAE J2953/3 establishes the test cases to ensure the interoperability of Plug-In Vehicles (PEV) and Electric Vehicle Supply Equipment (EVSE) for multiple suppliers.
The Recommended Training Practices document will cover guidelines / recommendations for each of the certification levels and endorsements for the J3300 Driving Skills Standard. The document will provide information on all the skills that candidates are expected to have at each certification level. It is intended to provide a general, but complete basis for training, beyond what the candidate must demonstrate in the skills assessment for each certification level.
This Recommended Practice is intended to establish a procedure to certify Automated Driving System fallback test driver skill levels. This certification can be used by the individual driver to qualify their skills when seeking employment or other professional activity as a test driver of vehicles with automated driving features. These certification levels may also be used by test facilities or other organizations when seeking test or professional drivers with these skills. This document provides directions for obtaining certification through Probitas Authentication® and associated Automated Driving System fallback test driving skill examination requirements. This document is a supplement to SAE J3300, providing information specific to the Automated Driving System fallback test driver skill certification and clarifying the application of the rules set forth in SAE J3300 to the Automated Driving System fallback test driver certification.
This recommended practice defines methods for the measurement of periodic, random and transient whole-body vibration. It indicates the principal factors that combine to determine the degree to which a vibration exposure will cause discomfort. Informative appendices indicate the current state of knowledge and provide guidance on the possible effects of motion and vibration on discomfort. The frequency range considered is 0.5 Hz to 80 Hz. This recommended practice also defines the principles of preferred methods of mounting transducers for determining human exposure. This recommended practice is applicable to light passenger vehicles (e.g., passenger cars and light trucks). This recommended practice is applicable to motions transmitted to the human body as a whole through the buttocks, back and feet of a seated occupant, as well as through the hands of a driver.

This SAE Information Report describes results of testing of the SAE J1746 ISP-Vehicle Standard for the communication of spatial data references between central sites and mobile vehicles on roads. Testing was performed by the Oak Ridge National Laboratory and its contractors, resulting in a document from which this Information Report has been extracted. Tests were performed by computer analysis and corroborated by field tests with a mobile vehicle.
A bolt-load retention (BLR) test is a practical test to determine the bolt load of a fastener joint with time and at given temperatures. There are three types of BLR tests described in this standard, namely general-purpose test, design-purpose test, and screening material test. A general-purpose BLR test may be used for screening materials, while a design-purpose BLR test is usually used to verify the BLR behavior of a specific joint. The screening material test is an example of the general-purpose test for typical automotive applications.
