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

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

Page 13: Creative Journey - Pedal Box FSAE17

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.
