2. Background Information Hoyt Conventional drive train- torque is applied from an internal combustion engine Hybrid vehicle drive train- An electric motor and/or an internal combustion engine can apply torque to the drive wheels ICE Axle Assembly Power Split Device ICE Generator Electric Motor Axle Assembly Battery Bank Generator Electric Motor Axle Assembly ICE ConventionalHybrid- ParallelHybrid- Series

3. Problem Statement: Vermont Technical College would like to compete in the Dartmouth Thayer School of Engineering Formula One Hybrid Racing Competition, but we do not currently have a vehicle that meets the specifications. Farley

4. Solution Statement: To develop and construct a hybrid propulsion system which meets the following requirements 1. Comprises both an internal combustion engine (ICE) and an electrical storage unit with electric drive 2. The system shall meet all electrical specifications and requirements for the 2007 Dartmouth Thayer School of Engineering Formula One Racing Competition. 3. The drive system may deploy the ICE and electric motor(s) in any configuration including series and parallel. 4. Final design will allow the drive train system to be adapted to a chassis developed in a separate effort. Farley

5. System Overview Frost Hybrid Propulsion System Overview Low Pressure Feedback Battery Bank ICE Generator Electric Motor Power Split Device Axle Assembly Accumulator V+ Hydraulic Pumps 4 port, 2 way valve Check valves The rotational input from both the electric motor and ICE will drive hydraulic pumps to pressurize the accumulator. The hydraulic pressure will act on hydraulic motors positioned at the drive wheels to power the vehicle. Regenerative braking will allow the hydraulic motors to pressurize fluid back into the accumulator for future use. Hydraulic Motors

14. Completed -Mathematical Modeling of Electric Motor and ICE subsystems -System overview diagram -All subsystems designed and defined; Hydraulic, Electrical, Regenerative Braking, ICE & clutch assembly -Certification in ISO 9002 Yet to be Completed -Subsystems need to undergo comprehensive component testing for functionality and rationality. -Purchase a better ICE -Locate differentials for demonstration between the ICE and Electric motor -Write software for state controls diagram -Physically model the hydraulic subsystem using pneumatics or miniature hydraulic apparatus -Purchase electrical charge accumulators Major Milestones

15. Summary In order to compete in the Thayer School of Engineering Formula One Hybrid Competition, a hybrid drive-train is essential. Team Hybrid will design and construct a hybrid propulsion system that meets the required specifications. The overall drive train consists of three subsystems which are currently undergoing feasibility testing for functionality and rationality. Farley
