Overview
• 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
Brainstorming
• Scope Document
• Gant Chart/Timeline
• System Flowcharts
Methods & Procedures
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
FlowchartsMethods & Procedures
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
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
Design• User Control of the system:
– The throttle pedal determines what mode the hybrid system is in: charging or discharging.
Methods & Procedures
Implementation
• Download Simulink code to truck
• Control the truck with manual switches
• Gather data from MotoTune and Serial Data Link
Methods & Procedures
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
Switch Bang-Bang Subsystem
• 2 Input Switches• 3 Digital Actuators
Milestones & Roadblocks
Displacement ControllerMilestones & Roadblocks
Serial Communication
• J -1708 Protocal
• Data Structure– PID – Identifier– Data – Bit Resolution
Milestones & Roadblocks
Future Plans
• Complete Automation of Parallel Truck Configuration
• Optimize Automation Controller for Fuel Economy
(It’s a smart Truck)
Future PlansSerial Communication
• Current Design– Parallel System
• Redesign controller:– Torque Split Transmission– Increase Control
Complexity– Throttle control
regeneration
BudgetSummary:• 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
Special Thanks
