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 (H30) and steering wheel diameters (W9) less than 405 and 450 mm, 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 530 mm and steering wheel diameters (W9) between 450 and 560 mm with treadle type pedals. (Class B Vehicles) See Figure 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.
