Vehicular precise positioning system reference architecture

2021-12-07
WIP
J3269
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.

Test Procedures for Precise Positioning Systems for Passenger Vehicles

2021-12-07
WIP
J3270
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.

Megawatt Charging System for Electric Vehicles

2021-12-15
WIP
J3271
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.

Puget Sound Ecosystem Source Analysis Review

2020-01-15
WIP
J3225
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.

WIP
J2945/D
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

Vehicle Sound Measurement at Low Speeds

2009-01-16
WIP
J2889
The Vehicle Sound for Pedestrians Subcommittee of the SAE Safety and Human Factors Committee is developing a test procedure to determine the sound output of electric and hybrid-electric powertrain vehicles at certain low-speed conditions. Establishing a consistent method of measuring the sound output of these vehicles will facilitate further study into the need for additional measures to alert pedestrians to the presence of these vehicles in traffic. This test procedure could also become industry practice should it later be deemed necessary to record the sound output of certain vehicles in low speed traffic conditions where vehicles, pedestrians and other road users are co-mingled.
