Why multi-disciplinary

ECET department within College of Science, Engineering and Technology (CSET) Auto & Manufacturing Technology Biology Chemistry & Geology Engineering (EE, ME, Civil E) Interior Design & Construction Management Physics & Astronomy Mathematics & Statistics Computer and Information Sciences

Practical vs. Idealistic reasons

Dept. Curriculums in Engineering & Technology

• Stronger focus on Mathematics and systems modeling concepts in traditional engineering disciplines versus technology programs.

Divergence of emphasis around Spring semester of the second academic year

Dept. Curriculums in Engineering & Technology

Traditional Disciplines

General Education (Fundamental sciences, mathematics and introductions to the discipline courses)

Theoretical engineering focus to content.More mathematically rigorous.More comprehensive senior design projects.Signals and SystemsElectromechanicsDigital Signal Processing

Technology Disciplines

General Education (Fundamental sciences, mathematics and introductions to the discipline courses) Integrated Applied/Laboratory focus

Applied engineering focus to content.Less mathematically rigorous. Understanding Computers Electronic shop practices Advanced Instrumentation C++ Programming

Hybrid Vehicle Systems Course Outline

How do the backgrounds of students stack up against the content?

Hybrid Vehicle Systems Course Outline

Hybrid Vehicle Systems Course Outline

Course enablers are sufficient for upper level undergraduate or graduate level hybrid vehicle systems course

Integrating Course Content

Hybrid vehicle systems are about combining multiple power sources to provide torque to the wheels and combining multiple energy storage mechanisms in one platform

Pick quantities to start which are understood by all students in multiple disciplines

Power Electrical Mechanical Automotive (HP scaled

by torque))( TP

)( vFP

Integrating Course Content

Consider the optimization flow and systems design aspects of iterating model parameters

Power components can be described as simple parameterized functions of conceptually known quantities

Integrating Course Content

Describe function components using discretized forms

Vehicle dynamics example

Integrating Course Content

Combine models through a mechanical connection the planetary gearset (Prius, Escape Hybrid) or through the driveline (Honda ISA, others)

Course Development and Plans

2 credit course in the Fall 2007 semester (with abbreviated topics coverage) Joint teaching between ECET and AET Lecture and Laboratory content Introduction to analysis tools

– ADVISOR or alternate

– Battery system dynamic model simulations

– Automotive performance and emissions

– Communications network software (CAN protocol)

Course Development and Plans

1 three credit course and 1 two (or three) credit course planned for future years First course

– Lecture with some lab content on complete course topics

Second course– Vehicle design project course similar in scope to a senior

design project where student groups complete applied hybrid vehicle project

Joint teaching between ECET and AET
