VSC-A presentation - ISO TC204 Standards Workshop Sept 08 JBK.ppt

  1. 1. Vehicle Safety Communications - Applications ( VSC-A ) John B. Kenney Toyota InfoTechnology Center [email_address]
  2. 2. VSC-A Project <ul><li>3 year project - December 2006 to December 2009 </li></ul><ul><li>Collaborative effort between 5 OEMs (Daimler, Ford, GM, Honda & Toyota) and US DOT </li></ul><ul><li>Goal: Determine if DSRC @5.9 GHz & vehicle positioning can improve upon autonomous vehicle-based safety systems and/or enable new communication-based safety applications </li></ul><ul><li>Follow-on project to CAMP/DOT VSC I (2002-2004) project and CAMP internal Emergency Electronic Brake Lights (EEBL) project </li></ul><ul><li>Strong emphasis on resolving current communication and vehicle positioning issues so that interoperable future deployment of DSRC+Positioning based safety systems will be enabled </li></ul>
  3. 3. VSC I 2002 - 2004
  4. 4. <ul><li>Develop scalable, common vehicle safety communication architecture, protocols, and messaging framework necessary to achieve interoperability and cohesiveness among different vehicle manufacturers </li></ul><ul><ul><li>Standardize this messaging framework and the communication protocols (including message sets) to facilitate future deployment </li></ul></ul><ul><li>Develop accurate and commercially feasible relative vehicle positioning technology needed, in conjunction with the 5.9 GHz DSRC, to support most of the safety applications with high potential benefits </li></ul><ul><li>Develop and verify (on VSC-A system test bed) a set of objective test procedures for the selected vehicle safety communications applications </li></ul>VSC-A Main Objectives
  5. 5. Level I test bed implementation 2009 2008 2007 VSC-A Research Activities and Timeline Crash scenarios & safety apps. selection DSRC+Positioning safety system conops, requirements and minimum perf. specs. DSRC+Positioning and autonomous Sensing safety system analysis Objective test procedures development Coordination with standards development activities and other USDOT programs SAE, IEEE DSRC, CICAS-V, VII, Europe Car2Car, Japan ASV System testing and objective test procedures Benefit analysis support to USDOT, Volpe & Noblis Level II test bed implementation June 2008 April 2009 Relative vehicle positioning development Message composition, standardization, security and communication protocols Vehicle safety system test bed System design, algorithms (path prediction, threat, warning) & in-vehicle integration
  6. 6. VSC-A Test Bed System Development Mapping of applications to crash scenarios EEBL : Emergency Electronic Brake Lights FCW : Forward Collision Warning BSW : Blind Spot Warning LCW : Lane Change Warning IMA : Intersection Movement Assist DNPW : Do Not Pass Warning Note : Crash Scenario reference: “VSC-A Applications_NHTSA-CAMP Comparison v2” document, USDOT, May 2 2007. Selected based on 2004 General Estimates System (GES) data and Top Composite Ranking (High Freq., High Cost and High Functional Years lost).  LTAP/OD at Non-Signalized Junctions 8   Vehicle(s) Changing Lanes – Same Direction 7  Vehicle(s) Not Making a Maneuver – Opposite Direction 6   Lead Vehicle Decelerating 5  Straight Crossing Paths at Non-Signalized Junctions 4  Vehicle(s) Turning at Non-Signalized Junctions 3  Control Loss without Prior Vehicle Action 2  Lead Vehicle Stopped 1 CLW IMA DNPW LCW BSW FCW EEBL V2V Safety Applications Crash Scenarios
