Describing the Truck Driver Eye and Head Accommodation Tools

1987-08-01

Truck driver eye and head position tools have been developed to describe where certain percentages of truck drivers position there eyes and heads in various workspace arrangements. Separate equations describe the accommodation level for driver populations with male to female ratios of 50/50, 75/25, and a range from 90/10 to 95/5. These equations can be used as a design tool to locate the curves in vehicle space to describe the region behind which the given populations eyes and heads would be located. Equations and curves are provided for both the drivers eye and head in the side view. It has become increasingly apparent that there is a need for improved methods of accommodating truck drivers in heavy truck cab design. Currently, practices used in the automobile industry for passenger car design are utilized for the design of heavy trucks. These practices.

Describing the Truck Driver Stomach and Shin-Knee Accommodation Tools

Truck driver shin-knee and stomach postion tools have been developed to describe where certain percentages of truck drivers position there knees and stomachs in various workspace arrangements. Separate equations describe the accommodation level for driver populations with male to female ratios of 50/50, 75/25, and a range from 90/10 to 95/5. These equations can be used as a design tool to locate the curves in vehicle space to describe the region behind which the given populations shin-knees, and stomachs would be located. Equations and curves are provided for both the left leg, which operates the clutch, and the right leg, which operates the accelerator.

Describing the Truck Driver Workspace

1985-12-01

This paper describes the philosophy and development of several functional anthropometric tools currently proposed for use in heavy truck workspace design. These functional tools are statistical models which describe the probabilistic location in heavy truck space of the body landmarks of populations of truck drivers with various percentages of males and females as a function of vehicle packaging parameters. Such tools provide the manufacturer with design flexibility to develop workspaces that maximize accommodation rather than restricting all manufacturers to one cab design dictated by design standards. Models in this paper were developed for truck driver populations with 50%/50%, 75%/25%, 90%/10%, and 95%/5% male to female ratios to enable design for a specific user group.

Truck Driver Selected Seat Position Model

1986-08-01

A truck driver selected seat position tool has been developed to describe where certain percentages of truck drivers position horizontally adjustable seats in various workspace arrangements. The curves describe the 2.5th, 5th, 10th, 50th, 90th, 95th, and 97.5th percentile accommodation levels expressed as H point locations aft of the Accommodation Heel Reference Point as a function of vehicle H-point height (H30). Separate equations describe the accommodation level for driver populations with male/female percentages of 50/50, 75/25 and from 90/10 to 95/5. The equations can be used as a design tool to estimate the location and length of horizontal seat travel to provide accommodation of target percentages of truck drivers. The equations can also be used as a checking tool to estimate the level of accommodation provided by a given horizontally adjustable seat track.

Driver Selected Seat Position Model

Data from fourteen driver workspace studies have been used to develop a two dimensional model which defines driver selected horizontal seat position as a function of chair height for various percentile accomodation levels. The tool is referenced to a manikin ball of foot point and can be used for design and/or checking purposes.
