  1. Overview of LANE MANAGEMENT SYSTEM(LMS-1)Software Engineering CSE 435Michigan State UniversityFall 2012 • Team Manhattan • Project Manager : Eric Proper • Facilitator : Grace Lweendo • Customer Liaison : Duncan Finney • Configurations Manager : Jim Challenger • Customer : Dr. Ramesh, GM Global R&D • Instructor : Dr. Betty H.C Cheng* • *Please direct all inquiries to the instructor

  2. What is LMS? • System integrated into a vehicle to stop it from exiting the lane and/or drifting • Lane Centering • Lane Keeping • Alerts driver, audibly and visually.

  3. System Features • Three main features • LCS • LKS • LDWS • Enable/Disable • Button/switch • Activate/Deactivate • Quick override button • Turn signal • Speed

  4. Project Motivation • Convenience • Eases fatigue of Long Distance Trips • something else • Safety • Distracted Driving • 18% of injury crashes in 2010 were reported as distraction-affected crashes • Drunk Driving • In 2010, 10,228 people were killed in alcohol-impaired driving crashes, accounting for 31% of all traffic related deaths in the US

  5. Constraints • Limited autonomous control • Minimal control of steering • Failures that result in suspension of operation • Weather conditions (snow,ice,rain) • No or ambiguous lane markings • Too large of road curvature for system to capture markings. • Too much force for system to correct in time. • System-wide failures • If one subsystem fails the whole system suspends

  6. System Components • Six Functional Subsystems • Supervisory Control Subsystem • Camera Sensing Subsystem • Image Processing Subsystem • Lane Detection Subsystem • Vehicle State Estimation Subsystem • Path Prediction Subsystem

  7. Domain Research • Investigated Current Solutions • Lane Keeping Systems • Lane Departure Warning Systems • Application of Domain Knowledge • System Activation • System Intervention • Quick Override • System Vehicle Control

  8. PART II : Model Based View of the System

  9. PART III : Demonstration • System interface (5 views) • Control view • Interior view • Vehicle Position view • Road Curvature view • Scenario information view • 4 initial scenarios

  10. Scenario I : Straight Road • http://www.cse.msu.edu/~cse435/Projects/F2012/LMS-1/Prototype/protointerface.php

  11. Scenario II : Curved Road • http://www.cse.msu.edu/~cse435/Projects/F2012/LMS-1/Prototype/curvesproto.php

  12. Scenario III : No/Ambiguous Lane Markings • http://www.cse.msu.edu/~cse435/Projects/F2012/LMS-1/Prototype/nolaneproto.php

  13. Scenario IV : Subsystem Failure • http://www.cse.msu.edu/~cse435/Projects/F2012/LMS-1/Prototype/protofailure.php

  14. Acknowledgements • We gratefully acknowledge and appreciate the participation of our customer, Dr. Ramesh from GM Global R&D
