Advancing Integrated Vehicle-Based Safety Systems: IVBSS Initiative Overview and Progress

The Integrated Vehicle-Based Safety Systems (IVBSS) initiative aims to accelerate the integration of advanced safety technologies into the U.S. vehicle fleet. Targeting major crash types such as rear-end incidents, road departures, and unsafe lane changes, the IVBSS seeks to implement warning functions like Forward Crash Warning, Lane Change Warning, and Lateral Drift Warning. This paper outlines the program's overview, target crash problems, major activities, and the timeline of achievements from initial design to operational testing, ultimately aiming to reduce vehicular accidents and enhance safety on the roads.

  2. Outline • Program Overview • Target Crash Problem • Integrated System Warning Functions • Major Program Activities • Program Timeline • First Year Accomplishments • Summary – Key Program Dates

  3. Integrated Vehicle-Based Safety Systems (IVBSS) Initiative Goal:Work with industry to accelerate introduction of integrated safety systems into the U.S. vehicle fleet of light vehicles and heavy trucks Addresses three Crash Types: • Rear End • Road Departure • Lane Change/Merge

  4. Target Crash Problem Studies conducted by the U.S. DOT indicate that widespread deployment of an integrated system combining rear-end, lane change and roadway departure crash countermeasures could prevent a significant number of these crashes each year.

  5. Integrated System Functions • Forward crash warning (FCW) • Provides warnings to drivers to assist them in avoiding, or mitigating, crashes with the rear end vehicles traveling in the same direction

  6. Lead vehicle cut-ins/merges Approaching low-profile vehicle Approaching slower vehicle Motorcycle Lead veh lane change reveals stopped Approaching stopped vehicle Integrated System Functions • Forward crash warning (FCW) cont’d S P S P S S P P S P

  7. Integrated System Functions • Lateral driftwarning (LDW) • Provides warnings to drivers that are drifting from their lane

  8. Integrated System Functions • Lateral driftwarning (LDW) cont’d Drifting into adjacent lane Adjacent lane mayhave same- or opposite-direction travel S Drifting into adjacent occupied lane Warning occurs earlier with “hard” threat S P

  9. Integrated System Functions • Lane changewarning (LCW) • Provides full-time side object presence indication, as well as turn signal triggered warnings of unsafe maneuvers • Based on adjacent or approaching vehicles

  10. Integrated System Functions • Lane changewarning (LCW) cont’d Merging into occupied lane Driver warned P S

  11. Integrated System Function • Curve-speedwarning (CSW) • Provides warnings to drivers that they may be driving too fast for an upcoming curve. • Only on Light Vehicle platform

  14. Major Program Activities Phase 1: • Integrated System design and development • Development of functional requirements and performance specifications • Human Factors/DVI development • Building engineering development vehicles • Including integrated warning characteristics, high quality DVI, and prototype data acquisition system • Verification Testing – Objective test procedures • Independent Evaluation Planning • 12/07: Decision point for Phase 2 Phase 2: • Field Operational Test – fleet build, pilot testing • Evaluationof Safety Benefits

  15. IVBSS Program Timeline System Design (12/05-2/07) Driver Vehicle Interface (DVI) Development (12/05-8/07) Build and validate proto- type vehicles (8/06-11/07) FOT Pilot 1/08-6/08 Conduct FOT (7/08-7/09) Independent Evaluation: Concept Definition/Planning (1/06-12/07) Independent Evaluation: Field Data Evaluation (11/08-3/10) Phase One Phase Two Functional Requirements 6/06 Performance Specifications 11/06 Objective Tests 9/07 FOT Begins 7/08 FOT Ends 7/09 Program Ends 11/09 Program Begins 11/05 FOT Go/No Go 12/07

  16. First Year Accomplishments • System Design and Development underway • Demonstration of initial FCW and LCW capability • Initial DVI Experiment completed • DVI Option Space defined • Key Program Documents produced • System Architecture • Preliminary Functional Requirements • Preliminary Performance Specifications • Draft Set of Objective Test Procedures • Draft Independent Evaluation Plan

  17. Summary – Key Program dates • July-August 2007 – Prototype vehicles ready for testing • August 2007 - Driver Vehicle Interface design complete • November 2007 – Objective testing completed • December 2007 – Phase 2Go/No-Go Decision • January-June 2008 – Fleet build and pilot testing • July 2008-June 2009 – Full-scaleFOT; data collection • January 2010 – Final Program Report publicly available • June 2010 – Independent Evaluation (Safety Benefits) Report
