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
