Purpose

Assembly line covering the complete pedal box.

Function

Groups the brake and accelerator pedal assemblies, the trays, the rail, the balance bar hardware and the adjustment mechanism. Design Philosophies and Processes: Inherited from the Ergonomics subsystem design process: 1. Take driver body measurements and place them against the ergonomics study ranges. 2. Mold the seat insert to the driver in the car with expanding foam, then hand post-process and cover. 3. Set headrest and harness mounting to the rules and to the driver's shoulder height. 4. Run a simulator or on-track endurance stint and measure fatigue with EMG. 5. Iterate the insert shape at the identified pressure and support points.
