7. Purpose: Increase energy recovery by 50% from braking Increase fuel economy by 20% to 30% thereby reducing emissions Provide inexpensive solution for developing infrastructures and highly polluted areas Goals and Objectives

8. Brainstorming Scope Document Gant Chart/Timeline System Flowcharts Methods & Procedures

9. Timeline Fall Semester – Test individual modules – Wrap all modules in automated supervisory controller Spring Semester – Begin modeling new torque split hybrid system – Have new torque split controller automated and ready by E-Days Methods & Procedures

10. Flowcharts Methods & Procedures

11. Design Constraints & Criteria – The control system must not interfere with the normal safety of the vehicle – The controller must be compatible to any vehicle – The automation of the control system should not drastically change the operation of the vehicle Methods & Procedures

12. Design The system: – Displacement pump stores and releases hydraulic energy – The transfer case allows us to switch between hydraulic and non-hydraulic mode Methods & Procedures

13. Design User Control of the system: – The throttle pedal determines what mode the hybrid system is in: charging or discharging. Methods & Procedures

14. Implementation Download Simulink code to truck Control the truck with manual switches Gather data from MotoTune and Serial Data Link Methods & Procedures

15. Milestones & Roadblocks Rewired truck inputs to engine control unit Achieved serial communication Implemented bang-bang control switches Able to track and control displacement pump Semi-automated control of vehicle

16. Switch Bang-Bang Subsystem 2 Input Switches 3 Digital Actuators Milestones & Roadblocks

17. Displacement Controller Milestones & Roadblocks

18. Serial Communication J -1708 Protocal Data Structure – PID – Identifier – Data – Bit Resolution Milestones & Roadblocks

19. Future Plans Complete Automation of Parallel Truck Configuration Optimize Automation Controller for Fuel Economy (It’s a smart Truck)

20. Future Plans Serial Communication Current Design – Parallel System Redesign controller: – Torque Split Transmission – Increase Control Complexity – Throttle control regeneration

21. Budget Summary: Initial funding from Czero of $50k In 2008, Czero received another $25k from the Fort Collins Governor to continue the hydraulic hybrid project MotoTron donated ECU controllers for the truck Kept accurate records of our purchases and donations
