Driver Selected Seat Position for Class B Vehicles - Seat Track Length and SgRP

2011-10-27
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 DriverS Viewing Environment

1995-03-01
HISTORICAL
J1750_199503
This SAE Recommended Practice establishes two uniform methods for describing and evaluating the truck driver's viewing environment, the Polar Plot and the Horizontal Planar Projection. 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. This document relates to the driver's exterior visibility environment and was developed for the heavy truck industry (Class B vehicles, class 6, 7, 8 vehicles) although the projection principles presented in this document can be applied to any class of motor vehicles. This document is intended to complement SAE J1050a and provides a visual format that can describe the driver's entire viewing environment.

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.

Location and Operation of Instruments and Controls in Motor Truck Cabs

1988-09-01
HISTORICAL
J680_198809
The location and operation of instruments and controls herein described are recommended for adoption by manufacturers of trucks and truck-tractors in new or revised designs in order to avoid confusion when drivers shift from one truck to another, to promote safety and convenience, and to simplify design, production, and servicing. This recommended practice shall apply to all on-highway trucks and truck-tractors equipped with power brake systems and having a GVW rating of 26 000 lb or more. Of prime importance in this recommended practice is the basic premise that all controls requiring operation while the vehicle is in motion be located so that the driver can manipulate them with his right hand and keep his left hand on the steering wheel. Controls operated only when the vehicle is not in motion, such as the ignition key, starter switch, and engine shutdown, may be located at the left side of the instrument panel and be manipulated with the driver's left hand.

Accommodation Tool Reference Point for Class B Vehicles

CURRENT
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.
