4. Baja SAE is a design and engineering competition as much as it is a racing series • RIT Baja competes all across North America against 100+ other teams • RIT Baja designs and builds a custom off-road vehicle from the ground up Project Background What is Baja SAE?

5. Vehicles must be able to handle all variety of rough terrainwhile excelling on challenging courses. • Vehicle success centers around efficiency, acceleration, and maneuverability, and driver skill. Project Background

6. The RIT Baja Team has expressed an interest in improving drivetrain efficiency and dynamic control. The drivetrain has not had a significant format change since the 90’s, using a single speed reduction box coupled with a CVT. While this has been and continues to be an effective means of transmitting power to the wheels, and is the preferred solution amongst the top performing teams, the team would like to explore other options; specifically a gas-electric design. The team would like to receive a working bench top prototype of the drive system for the purpose of testing the gas electric system to compare it to the existing system. Problem Statement

8. Possible Advantages of Electric Drivetrain • Increased efficiency • Improved acceleration • Independent engine and wheel speed • Excess power storage • Regenerative braking • Active torque biasing

9. Punctual • Arrive on time to meetings • Reply to messages • Finish assigned work in a prompt, efficient, and thorough manner • Keep the schedule in mind and always strive to meet deadlines Norms and Values The Five P’s

10. Precise • Thoroughly investigate possible solutions to problems that may arise in an unbiased manner • Review all documents before submittal Norms and Values The Five P’s

11. Pleasant • Bring a positive attitude! Norms and Values The Five P’s

12. Productive • Time will be used in an effective manner • Strive toward completing the team’s goals and avoid tangents Norms and Values The Five P’s

13. Professional • Respect each other • Respectother teams in a polite and constructive manner • Respect the customer and the customer’s wants/needs Norms and Values The Five P’s
