Overview of Project ADS Software Engineering CSE435Michigan State UniversityFall 2013 Team members: Project Manager: Alec Dutch Facilitator: Duncan Young Customer Liason: Taylor Jones Configuration Manager: Cameron Keif • Customer: Eileen Davidson, Ford Motor Company Instructor: Dr. Betty H.C. Cheng* *Please direct all inquiries to the instructor.
Project Overview • Assisted Direct Start • Turns off engine when not needed • Increases gas efficiency
Overview of Goals • Increase gas efficiency • Ensure vehicle functionality remains unhindered • Allow driver to disable the system • Maintain vehicle safety
Considerations • Engine temperature • Battery level • Speedometer reading • Pedal states
Domain Research • Investigated Ford quick start technology • System in use already (2013 Fusion) • System execution • Fuel economy • Engine restart time
Project Constraints • Project Constraints • Sensor dependability • Quick start technology • Temperature requirements (200F) • Battery requirements (15%) • User comfort and safety
ADS System States Enabled if: • engine temperature > 200 degrees F • car is not in park Disabling actions: • car is in park • engine temp falls below 200 F
Engine States Engine off: • When speed falls below 2.5mph only if: • cabin temp is acceptable • battery is above 20% Engine on when: • acceleration pedal pressed • temperature moves out of acceptable range • battery falls below 15% • ADS is disabled
Part II: Model-based View of System • Class Diagram • Relationship between ADS and subsystems • State Diagram • Transitions between states of ADS system
Part III: Demonstration • Prototype layout • User interface and display • Scenarios • prototype use and system functionality
Prototype Layout Simulation Window • Buttons and animations • User interface for system
Prototype Layout system panel • Displays system variables • Includes buttons which change settings and scenarios
Prototype Layout status panel • Green- instructions and scenario text • White- events • Black- system changes which result from events
Scenarios • Standard operation • User disables ADS • Driver comfort vs. Fuel economy modes
