ACCOMMODATION TOOL REFERENCE POINT
1985-10-01
HISTORICAL
J1516_198510
Reference lines have been developed to which driver workspace accomodation tools can be located in vehicle space. The lines describe horizontal reference point locations as a function of vehicle H-point height (H30). One reference line has been established for use in vehicles with H-point heights (H 30) and steering wheel diameters (W9) less than 405mm and 450mm, respectively. (Class A Vehicles) This point can be used to reference appropriate workspace tools to accommodate a driver population with a male to female ratio of one to one. Separate reference lines have been established for use in vehicles with H-point heights (H30) between 405 and 530mm and steering wheel diameters (W9) between 450 and 560mm with treadle type pedals. (Class B Vehicles) See Fig. 1. Three lines are available for use in Class B vehicles depending on the percentages of males and females in the population the designer wishes to accommodate.

J1516_201110
This Recommended Practice provides procedures for defining the Accelerator Heel Point and the Accommodation Tool Reference Point, a point on the seat H-point travel path which is used for locating various driver workspace accommodation tools in Class B vehicles (heavy trucks and buses). Three accommodation tool reference points are available depending on the percentages of males and females in the expected driver population (50:50, 75:25, and 90:10 to 95:5). These procedures are applicable to both the SAE J826 HPM and the SAE J4002 HPM-II.

Driver Selected Seat Position

HISTORICAL
J1517_199812
A driver selected seat position tool has been developed to describe where certain percentages of drivers position horizontally adjustable seats in various workspace arrangements. The tool consists of series of equations that describe horizontal H-point locations as a function of vehicle H-point height (H30). One series of equations have been established for use in vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405 mm and 450 mm, respectively (Class A Vehicles). This class of vehicles includes passenger cars, vans, and light trucks. The lines describe the 2.5th, 5th, 10th, 50th, 90th, 95th, and 97.5th percentile accommodation levels expressed as H-point location for a driver population with a male-to-female ratio of 1:1.

CURRENT
J1517_201110
This Recommended Practice provides a procedure to locate driver seat tracks, establish seat track length, and define the SgRP in Class B vehicles (heavy trucks and buses). Three sets of equations that describe where drivers position horizontally adjustable seats are available for use in Class B vehicles depending on the percentages of males to females in the expected driver population (50:50, 75:25, and 90:10 to 95:5). The equations can also be used as a checking tool to estimate the level of accommodation provided by a given length of horizontally adjustable seat track. These procedures are applicable for both the SAE J826 HPM and the SAE J4002 HPM-II.

Describing and Evaluating the Truck Driver's Viewing Environment
2010-10-22
CURRENT
J1750_201010
This SAE Recommended Practice establishes three alternate methods for describing and evaluating the truck driver's viewing environment: the Target Evaluation, the Polar Plot and the Horizontal Planar Projection. The Target Evaluation describes the field of view volume around a vehicle, allowing for ray projections, or other geometrically accurate simulations, that demonstrate areas visible or non-visible to the driver. The Target Evaluation method may also be conducted manually, with appropriate physical layouts, in lieu of CAD methods. The Polar Plot presents the entire available field of view in an angular format, onto which items of interest may be plotted, whereas the Horizontal Planar Projection presents the field of view at a given elevation chosen for evaluation. These methods are based on the Three Dimensional Reference System described in SAE J182a.
