The following is a summary for SAE J2807 SAE J2807 is a standardized guideline that defines how Gross Combination Weight Rating (GCWR) and Trailer Weight Rating (TWR) should be determined for passenger vehicles, SUVs, and light-duty trucks. The standard ensures a consistent, objective, and fair comparison of towing capacities among different manufacturers. 1. Purpose and…
The following is a summary of SAE J1517. Scope A driver-selected seat position tool has been developed to estimate where drivers of varying sizes will place horizontally adjustable seats in different vehicle types. This tool uses equations that predict horizontal H-point (seat position) based on vehicle H-point height (H30) and steering wheel diameter (W9). The…
The following is a summary of SAE J1516. Scope Reference lines have been created to guide the positioning of driver workspace accommodation tools within vehicle space, based on horizontal reference points tied to H-point height (H30). For Class A vehicles (H30 under 405 mm and steering wheel diameter under 450 mm), a single reference line…
The following is a summary of SAE J1100. Scope This SAE Recommended Practice defines standardized measurements and procedures for vehicle dimensions, focusing primarily on design intent within a CAD environment, although some measurements can also be taken on physical vehicles. Variations may occur between design and actual measurements, and care should be taken not to…
The following is a summary of SAE J1052. Forward Foreword—Changes in This Revision—This document has been updated to align with the changes made to SAE J941 eyellipses. While the size and shape of the head position contours remain unchanged, their positioning in Class A vehicles has been adjusted upward and rearward. The procedure for locating…
The following is a summary of SAE J4004. Forward This document outlines the guidelines for positioning and posturing the H-point design tool (HPD) and establishing key reference points like the seating reference point (SgRP) used in designing driver and passenger seat positions. It introduces a new method for determining driver seat track length and positioning…
1. Scope This SAE Recommended Practice establishes methods for describing and measuring the driver’s field of view. The document describes three methods for measuring the direct and indirect fields of view and the extent of obstructions within those fields. The first method uses any single pair of eye points to determine the fields or obstructions…
The following is a summary of SAE1999-01-1336 Measured Vehicle Inertial Parameters. To view the original document see the attached PDF. SAE1999-01-1336 Measured Vehicle Inertial Parameters – Abstract The paper presents an updated listing of the National Highway Traffic Safety Administration’s (NHTSA) Light Vehicle Inertial Parameter Database. It includes vehicle inertial parameters measured up until September…
Foreword – This SAE Recommended Practice describes the eyellipse, a statistical representation of driver eye locations, which is used to facilitate design and evaluation of vision in motor vehicles. Examples of eyellipse applications include rearview mirror size and placement, wiped and defrosted areas, pillar size and location, and general exterior field of view. These applications…
Foreword—This Document was not changed other than to put it into the new SAE Technical Standards Board Format. 1. Scope —The devices of this SAE Standard provide the means by which passenger compartment dimensions can be obtained using a deflected seat rather than a free seat contour as a reference for defining seating space. All…
