1	V2V Safety Research Track 2 - Interoperability Mike Lukuc NHTSA August 2, 2011
2	OVERVIEW V2V Interoperability The ability for V2V safety systems to successfully function across any, and all, equipped vehicles regardless of make/model Research Team Collaboration between USDOT and Crash Avoidance Metrics Partnership (CAMP) Vehicle Safety Consortium 3 (VSC3) Team members: NHTSA, RITA ITS JPO, Ford, GM, Honda, Hyundai-Kia, Mercedes Benz, Nissan, Toyota and VW-Audi
3	Task 2 - Coordination with Other Related USDOT Programs Goal: Coordination of V2V-Interoperability research results with other organizations, programs and technical activities
4	Task 2 - Activities Active participation in IEEE and SAE standards development Facilitation of international standards harmonization Interaction with USDOT Systems Engineering Task Interaction with other related USDOT activities Coordination with VII Consortium
5	TASK 3 - VEHICLE-TO-VEHICLE SAFETY COMMUNICATION INTEROPERABILITY Goal: To achieve V2V safety communications and security interoperability between On Board Equipment (OBE) systems from different manufacturers
6	TASK 3 - ACTIVITIES Specify OBE requirements for V2V safety communications and security interoperability Work with three-to-five suppliers to develop interoperable OBEs which support the requirements identified above Test the OBEs from the different suppliers to determine if interoperability has been achieved Analyze the test results and develop remediation recommendations to address any identified anomalies or gaps in the standards Incorporate remediation recommendations in relevant standards and back in the OBEs
7	TASK 4 - COMMUNICATIONS SCALABILITY Goal Conduct testing in real-world conditions with a sufficient number of vehicles and OBEs to determine if the planned channel congestion mitigation techniques will support large-scale deployment
8	TASK 4 - ACTIVITIES Test how DSRC will perform as larger numbers of DSRC radios are added to the system Calibrate communication simulation environments with real world large scale test data Identify congestion control and mitigation techniques likely to be the most effective at supporting the desired level of scalability Integrate security system (developed within Task 5) into the scalability test bed Incorporate remediation recommendations in relevant standards
9	TASK 4 – TIMELINE
10	TASK 5 - SECURITY MANAGEMENT Goal: Develop technical requirements and build a prototype security system, test this system, and utilize it within the scalability testing in Task 4
11	TASK 5 - ACTIVITIES Develop a functional security framework that does not presuppose the existence of any particular wireless technology Address all the functions that will be required in order to provide an effective security solution for vehicle safety applications Develop and define technical requirements for the functional nodes and interconnections among nodes Build a prototype security system capable of providing a technically feasible approach to guide policy decisions Test the prototype security system and analyze results Integrate the prototype security system with the scalability test bed
12	TASK 5 – TIMELINE
13	TASK 6 - DATA INTEGRITY AND RELIABILITY CERTIFICATION Goal: Assessment of requirements necessary for vehicles to trust the accuracy of the data in the over-the-air messages and allow the correct functioning of the safety applications
14	TASK 6 - ACTIVITIES Determine any differences in the outcome of the objective tests when the sensor data are varied within the current accuracy ranges Define procedures to ensure compliance with accuracy and timeliness requirements Define compliance verification and certification procedures Assess retrofit units (OEM-controlled design and installation) and aftermarket units (with no, or limited, connection with vehicle networks) in terms of capabilities and certification procedures Determine accuracy and trust requirements for vehicle safety applications that use autonomous braking and/or steering
