The SAE J3161/1 standard, revised in September 2024, provides essential requirements for onboard systems that support Vehicle-to-Vehicle (V2V) safety communications using LTE-V2X Sidelink. This document is critical for manufacturers aiming to build interoperable systems capable of exchanging Basic Safety Messages…

As automated driving systems (ADS) continue to evolve, the need for a common language to describe their behaviors and maneuvers becomes critical. SAE J3164-2023 addresses this need by providing a high-level ontology and lexicon for ADS-operated vehicle behaviors and maneuvers…

🛠️ Note: this article focuses on engineering interpretation, not clause-by-clause translation. As vehicle designs evolve to meet stricter safety and fuel economy standards, rear visibility has become increasingly compromised by higher beltlines. Camera Monitor Systems (CMS) offer a practical solution…

Improving bicyclist safety is a key goal for advanced driver-assistance systems. As Automatic Emergency Braking (AEB) systems become more prevalent, the automotive industry requires a standardized surrogate bicyclist target to ensure consistent testing and evaluation. SAE International’s J3157-2019 provides exactly…

SAE J314 is a long-standing standard from SAE International that defines requirements for wool and part wool felts used in surface vehicle applications. Originally issued in 1923, the standard has been reaffirmed multiple times and was stabilized in September 2022,…

Driver distraction remains a critical factor in road crashes, yet linking experimental measures of distraction to actual crash risk is not straightforward. SAE J3151-2018, titled Relating Experimental Driver Distraction and Driving Performance Metrics to Crash Involvement – Definitions of Terms…

The SAE J3152 Information Report provides a systematic framework for designing, fabricating, and installing brake NVH fixtures used in inertia dynamometer testing. By defining a clear taxonomy and including detailed guidelines, the standard aims to improve repeatability, reduce variability, and…

The rapid evolution of automated driving systems (ADS) has created a pressing need for clear, consistent language and a shared understanding of how these complex systems are structured. SAE International’s SAE J3131-2022, ‘Definitions for Terms Related to Automated Driving Systems…

SAE J3143:2019 establishes critical performance and testing requirements for non-metallic, non-reinforced assemblies used in automotive air-conditioning systems to contain and circulate refrigerant and lubricant. This standard is applicable to systems using R-134a, R-152a, or R-1234yf and PAG/POE compressor oils, over…

The SAE J3128–2019 standard establishes requirements for welded and cold drawn stainless steel pressure tubing, specifically grades 304 and 304L. This tubing is intended for hydraulic lines and other applications where corrosion resistance is critical. The standard covers manufacture, dimensions…
