43. The expert from ISO introduced GRVA-09-12, with a description of the Extended Vehicle concepts and the corresponding ISO standards. GRVA noted that ISO provided copies of ISO 20077-1 and ISO 20077-2 developed by the ISO Technical Committee (TC) 22 (GRVA-09-13 and GRVA-09-14).

44. The expert from CITA mentioned the existence of alternative models to the one presented by the expert from ISO (Extended Vehicle as in GRVA-09-12) and the Open Telematic Platform (OTP), mentioned in WP.29-178-10, also based on the ISO standards, developed by the ISO TC 204. He volunteered to present a comparison and an alternative, if other CITA members would also agree.

45. The expert from CEN (also member of ISO stated that he did not underestimate the work done on Extended Vehicles but asked whether there was a unique Extended Vehicle or one per manufacturer and, in that case, if they would be interoperable. He explained that this concept implied that the data is generated by the vehicle. He stressed that in fact, the vehicle was only one actor out of more than twenty in an Intelligent Transport System, that the vehicle was not the controller of that system, that the regulator and road operator determined the static road regulations and controlled the dynamic flow and management of traffic. He added that, the vehicle did not control its operating environment, that the vehicle could only achieve its journey within the control of the regulator and the dynamic control of the road operator. He wondered what involvement the extended vehicle had with the great intelligent transport system paradigm and its standards and controls. He asked it the extended vehicle functions within that paradigm or if it believed that the vehicle was the controlling element.

46. The expert from ISO explained that the Extended Vehicle concepts of the vehicle manufacturers were interoperable and that with this concept, the process of data exchange was initiated with a request issued by any stakeholder. He added that data would be made available to any kind of stakeholder independently from the service itself, in a safe and secure way and that the manufacturer would only check that data can be provided in a safe and secure way. He concluded that therefore the Extended Vehicle was not opposing to any type of system paradigm shift. GRVA agreed that further detailed exchange would be helpful, but GRVA could not further discuss this proposal, due to time constraints.
