Particulate matter (PM) emissions from engines and vehicles are measured gravimetrically using sample filters. With tightening emission standards, the need for accurate low-mass weighing has never been greater. SAE J2943-2022 provides comprehensive recommended practices for constructing and maintaining a filter…

Lane Keeping Assistance (LKA) systems are increasingly common in light-duty vehicles, providing momentary interventions to help prevent inadvertent lane departures. Unlike lane centering systems, LKA operates at SAE Level 0 and does not sustain automation of the dynamic driving task.…

The updated SAE Recommended Practice J2848-3-2021 provides a comprehensive framework for central tire inflation systems (CTIS) on medium- and heavy-duty highway vehicles. Whether you are designing an OEM system or integrating an aftermarket solution, understanding the functions, performance thresholds, and…

For engineers developing windshield washer systems for trucks, buses, and multipurpose vehicles with a GVW of 4,500 kg or more, SAE J1944-2012 provides a comprehensive framework of minimum performance requirements, standardized test procedures, and uniform terminology. This recommended practice ensures…

The SAE J1939-17 standard (issued December 2020) specifies a physical layer for SAE J1939 networks that use CAN FD (Flexible Data Rate) with a base baud rate of 500 kbps and a flexible data rate of 2 Mbps. This standard…

The SAE J2069 standard provides comprehensive guidelines for vehicle manufacturers to design and locate recovery attachment points on passenger cars, vans, and light trucks with a GVW up to 3,178 kg (7,000 lb). The primary goals are to minimize vehicle…

This article provides an overview of SAE J2310-2024, a recommended practice for designing rectangular cross section polymeric sealing rings used in automatic transmissions and hydraulic systems. The standard covers material selection, dimensioning, joint configurations, and critical design considerations such as…

The SAE J2540‑3 (2019) National Names Phrase List provides a standardized table of textual messages for expressing street and road names in Intelligent Transportation Systems (ITS). By assigning numeric indices to common name components—prefixes, main names, suffixes—the standard enables efficient…

Drivers develop strong expectations about how vehicle controls should move to achieve a desired effect. When a control’s motion aligns with these expectations—known as direction-of-motion stereotypes—using it feels natural and requires less thought. SAE J1139:2010 provides design recommendations that help…

The SAE J2594 standard, reaffirmed in 2023, provides a recommended practice for designing Proton Exchange Membrane (PEM) fuel cell systems with end-of-life recyclability in mind. As the transportation sector embraces hydrogen fuel cells, ensuring that these systems can be efficiently…
