Driver Seating Accommodation and Steering Wheel Location Models
J3099
1. SCOPE
This practice presents methods for establishing the driver workspace. Methods are presented for:
• Establishing accelerator reference points, including the equation for calculating the shoe plane angle.
• Locating the SgRP as a function of seat height (H30).
• Establishing seat track dimensions using the seating accommodation model.
• Establishing a steering wheel position.
Application of this document is limited to Class-A Vehicles (Passenger Cars, Multipurpose Passenger Vehicles, and Light Trucks) as defined in SAE J1100.
Rationale: This revision removes an outdated equation that provided an adjustment to account for the difference in length of the AHP to BOFRP between HPM-I and HPM-II, for finding SgRP. BOFRP has been common between HPM-I and HPM-II since J4002 was revised in 2010.
