In respect of 112-eCall (operating requirements defined in EN 16072)@ this document defines adaptations to eCall specifications defined in EN 16072 and other related documents to enable the provision of eCall for powered two wheel vehicles (vehicle centred). As with the existing provisions for eCall for Category M1/N1 vehicles@ these are specified within the paradigm of being OEM fit equipment supplied with new vehicles. For the purposes of the present document@ the P2WV ??L?? categories@ as defined in Directive 2002/24/EC@ Regulation (EU) No 168/2013@ UNECE and as referenced/specified in EN 15722 apply. This document includes only the requirements for Category L1 and L3 powered two wheel vehicles (vehicle based) with the exception of L1e-A (powered cycle)@ although CEN/TS 17249-6 may reference other ??L?? subcategories to use this document. (It will be noted that the categories L1 to L7 include 2@ 3 and 4 wheel types e.g. motorcycles@ tricycles and quadricycles.) NOTE 1 Other Technical Specifications may be prepared for other UNECE category ??L?? variants. NOTE 2 The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of other work@ and in respect of the operational requirements for any such aftermarket solutions for powered two wheel vehicles (vehicle centred)@ will use the specifications of this document as a principle reference point. NOTE 3 The 112-eCall paradigm involves a direct call from the vehicle to the most appropriate PSAP. (Third party service provision by comparison@ involves the support of an intermediary third party service provider before the call is forwarded to the PSAP.) The specifications herein relate only to the provision of 112-eCall or IMS-112- eCall (3.10)@ and do not provide specifications for third party service provision of eCall. NOTE 4 Some of the elements of this document will require further in depth analysis before they can be implemented in a European Standard. These elements are included in this document however to document the current state of development of a European Standard. The current state of development on these elements justifies their inclusion in this document@ but further assessment and analysis might require an amendment before implementation into a European Standard. (This is a normal evolution from a Technical Specification to a European Standard.)
