Customer Input Project to Broad for Senior Design

Electrical Power Source Decided on Club History/experience Simplicity

Ground Up Vehicle Design Too Much Starting Chassis Required

Frame, wheels, brakes, suspension, seating Road Registration of a Motorcycle simpler than

car registration Less stringent Safety requirements 3 Wheel loop hole

Mission Statement:To design and implement an electric drive system on a rolling chassis provided by the Electric Vehicle

Team that operates at highway speeds and has a long enough range to compete in the Green Grand Prix

Constraints:Assume Rolling Chassis Ready by MSD I in FALL

includes: frame, wheels, steering, seating, brakes, suspension.

Able to register as a motorcycleOperates at highway speedsRange Appropriate for GGP

Next Steps/Concerns Rolling Chassis ready for powertrain

required by Start of Winter qtr. at latest, (preferred by Fall qtr.)

Funding for Vehicle, Budget Required Can’t achieve range w/ lead acid

batteries Approach Tesla for crash test car
