                                4
    Autonomous Sensing Technologies
   Sensors can be expensive
       Sensors have limited use outside auto industry - low volume
       ACC in 1999 - ~$2000 / ACC in 2007 - ~$1500
   Sensors difficult to package inside/outside vehicle
       Sensors can be large
       Restricted mounting locations due to field of view
   Sensors may have difficulty operating in certain conditions
       Cameras in fog, rain, and snow
       Radar in areas of high reflectivity
       Multiple sensors may be needed for detection/verification
   Data from multiple sensors can be computationally
    intensive
   Sensors have limited field of vision

                                                                      5

                                 6
          Enabling Technology – DSRC
 Dedicated Short Range Communications
 (DSRC)
     In 1999, FCC allocates spectrum for “Intelligent Transportation Systems (ITS)”
     In 2005, FCC dedicates 1 of 7 channels for vehicle safety communications
     Technology standardized as 802.11p “Wireless Access in Vehicular
      Environments (WAVE)”
     Transmission rates from 3 – 27 Mbps




                                                                                  7
    Cooperative Sensor Technology – V2X

   360° coverage when communicating with similarly
    equipped vehicles
   Greater situational awareness through information
    exchange
   Up to 1000m of communication range (line-of-sight)
   Leverages existing Wi-Fi communication standards
   High volume, low cost hardware useful in a broad
    range of applications


                                                         8
Cooperative Safety Requires…Cooperation!




                                     9
Completed V2V Consortium Efforts
   Vehicle Safety Communications – Applications (VSC-A,
    VSC2 Consortium)
     Follow-on to Vehicle Safety Communications (VSC)
      project
     3-Year project completed in 2009
     Focus on pre-deployment elements needed for DSRC-
      based safety
        Over-the-air (OTA) interoperability
        Wireless security
        Protocol standards
        Relative vehicle positioning using GPS
        Communications scalability


                                                           10
    Pre-Deployment Efforts in VSC-A
   Over-the-air Interoperability
       IEEE 802.11p / 1609.4 for PHY+MAC
   Wireless Security
       IEEE 1609.2, consortium developed
        methods/enhancements (Verification On-Demand)
   Protocol Standards
       SAE J2735 for message sets, data frames and data
        elements, encoding/decoding
   Relative GPS positioning
       Exploration of GPS solutions for lane-level relative
        positioning (dead-reckoning, RTK, mixed modes,
        etc…)

                                                               11
    Pre-Deployment Efforts in VSC-A
   Communications Scalability
       DSRC Pods developed to assist with preliminary DSRC
        scalability testing
            Each pod supports two DSRC radios
            Scalability testing supported up to sixty DSRC radios
       Design of Pods allowed for static testing or use on fleet of
        non-DSRC instrumented vehicles (minimize cost)
       Test bed evaluated current communication methods and
        standards in congested environments
       Results exposed deficiencies in communication
        performance with existing communication standards

                                                                     12

Pre-Deployment Efforts in V2V-I
   Over-the-air Interoperability
       Evaluate V2V safety communication and security
        performance using On-Board Equipment (OBE) from
        various manufacturers
       Specify minimum performance requirements for V2V
        safety communications and security (SAE JXXXX)
       Evaluate adequacy of current communication and security
        standards using independent implementations
       Implement remedies for known technology deficiencies
        and provide feedback to standards bodies

    Pre-Deployment Efforts in V2V-I
   Communications Scalability
       Deploy up to 200 V2V nodes from various manufacturers
        in a controlled environment
       Move forward from simulations to create a real-world test
        bed of scale that can be centrally managed
       Evaluate standards based on unique manufacturer
        interpretations for:
            Reliability, Prioritization, Technological Stability, and
             Deployability
       Evaluation criteria will likely include Packet Error Rate,
        Number of Consecutive Packets Lost, End-End Message
        Latency, etc…

                                   Scalability Testing
   Test with Both static (red) and moving (green) vehicles
   Multiple Scaling increments (50, 100, 200+ vehicles)
   Employ control and mitigation techniques
   Integrate Security Solution
   Potentially incorporate RSE transmitting at higher power than
    vehicles




NOTE: The animation in this diagram is for illustration purposes only. The actual deployment of static and moving vehicles will
                                                                                                                         22
                                     be determined through the activities of this task.
    Pre-Deployment Efforts in V2V-I
   Security Management
       Develop a functional security framework to facilitate
        policy solutions that fall under the IntelliDriveSM policy
        roadmap activities
       Security framework efforts will include:
            Creation and operation of a centralized certificate authority
             including distribution and installation of certificates
            Develop methods to detect, report, and revoke “bad actors”
            Develop methods to create and distribute certificate revocation
             lists
            Develop efficient methods to authenticate sender and payload
            Analyze the risks to driver privacy under the chosen framework


                                                                           23
