  2. Agenda • Customer Needs • Engineering Specs • System Level Work • System Risks • Plans for Week 4

  3. Customer Needs • “Go faster” • Manual override • Easy to actuate • Internal energy source • Minimal impact on car electrical system • Actuate at least as fast as driver • High sensor resolution • Operate for the entire endurance event • Minimal mass • Control system in low temperature environment • Rapid maintenance

  4. Engineering Specifications • “Go faster” < 4 sec • Manual override Y/N • Easy to actuate lbf • Internal energy source Y/N • Electrical system impact max 2.3A, 14v • As fast as driver < 200 ms

  5. Engineering Specifications • Sensor resolution deg,in,psi/bit • Entire endurance > 200 shifts • Minimal mass 6-8 lb • System environ < 80°C • Rapid maintenance < 2 hr

  6. System Level – Functions • Automated clutch system to achieve maximum acceleration performance through tire/engine optimization

  7. System Level – Logic

  8. System Level – Pneumatics

  9. System Level – Packaging

  10. System Risks • Component lead times • Linear potentiometer (4-6 weeks) • Rotary potentiometer (5-7 days) • Pneumatic cylinder (3-6 weeks) • Cost/budgeting • Packaging constraints • Familiarity with involved systems • Engine • Control • Failure • Customer delays • Maintenance time

  11. Plans for Week 4 • High level feasibility studies • Functional decomposition • Determine clutch activation parameters • Determine ability to modulate clutch position • Determine necessary system resolution • Define system architecture • Start Simulink model
