Our Project – The Pedal Box• An integral part of the vehicle• Serves as a main point of
interaction for the driver• Integrates with braking and
electronics system• Overall weight and cost

FSAE Rules• The vehicle must accommodate drivers whose
stature ranges from 5th percentile female to 95th percentile.• Braking force of 2kN must be able to be sustained• 600N for 1.4G of deceleration

Main Issues and Areas of Focus:• Sliding/adjustment mechanism • Throttle oscillation• Brake bias control• Foot cups• Drive by wire potentiometer guard
Position Adjustment Solutions• Rollers on tracks (similar to drawers)• Big threaded bolt• Toothed shaft and torsion spring mechanism• Spring return• Pin operated rail mechanism

Vertical vs Horizontal Actuation
Throttle Oscillation Solutions• Stoppers/cushioning• Magnetic strips• Using software to create a dead zone• Adding dampening to the pedal as a whole

Compression spring with damper
Brake Bias Control• Decision between remote bias and
manual adjustment• Manual adjustment is more reliable
and less prone to being affected by vibration• Remote bias control is simpler to
adjust and more convenient
Foot Cups• Last years model had foot cups that travel with the
pedals, we intend to change that in order to improve driver comfort and simplicity of design.• Potential extension of foot cups in order to protect the
sensors from kicking/ other damage.
