VSC-A Project

• 3 year project - December 2006 to December 2009
• Collaborative effort between 5 OEMs (Daimler,
  Ford, GM, Honda Toyota) and US DOT
• Goal Determine if DSRC _at_5.9 GHz vehicle
  positioning can improve upon autonomous
  vehicle-based safety systems and/or enable new
  communication-based safety applications
• Follow-on project to CAMP/DOT VSC I (2002-2004)
  project and CAMP internal Emergency Electronic
  Brake Lights (EEBL) project
• Strong emphasis on resolving current
  communication and vehicle positioning issues so
  that interoperable future deployment of
  DSRCPositioning based safety systems will be
  enabled

VSC-A Main Objectives

• Develop scalable, common vehicle safety
  communication architecture, protocols, and
  messaging framework necessary to achieve
  interoperability and cohesiveness among different
  vehicle manufacturers
• Standardize this messaging framework and the
  communication protocols (including message sets)
  to facilitate future deployment
• 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
• Develop and verify (on VSC-A system test bed) a
  set of objective test procedures for the selected
  vehicle safety communications applications

Level I Over-the-Air (OTA) Message Format Draft

• Part I conforms to current draft J2735 Basic
  Safety Message (BSM).
• Fields after Part I are to potentially be added
  to Part II of BSM.

Current Program Activities and Status

• System Test Bed Development
• May 2008 Level I Implementation with core
  modules (Path Prediction, Path History and Target
  Classification) ready for engineering tests
• June 2008 All six V2V Safety Applications
  integrated and ready for engineering tests
• August 2008 CICAS-V application integration
• Communications and Standards
• Level I Development message set (flexible data
  elements) based on SAE standard J2735 (VSC I) and
  implemented as part of Level I test bed
• Security Three candidate protocols to enhance
  current standard (1609.2) to be evaluated in
  2008. HW SW implementation of all 3 protocols
  planned for Level I Test Bed
• IEEE 802.11 Task Group P (WAVE lower layers)
• Completed successful Letter Ballot May 3, 2008
• Vehicle Relative Positioning
• Currently evaluating benefits of sharing GPS raw
  information over DSRC link

Future Work

• Level I Refinements
• Safety Applications refinements
• OTA message optimization (minimize OTA size while
  supporting safety applications needs)
• Level II Design and Implementation
• Dual Radio Capability (Channel 172 usage)
• Power Control Testing (high and low power)
• Message Dissemination Protocols (use power, rate,
  and other controls to mitigate network congestion
  and improve message delivery)
• Vehicle Relative Positioning
• Integration of Forward Looking camera system to
  analyze potential improvements of V2V relative
  positioning
• Standards Participation
• Continue active involvement and contributions to
  establish/finalize standards (SAE and IEEE DSRC
  WAVE) to facilitate future potential deployment
