Overview

This Function shall be capable of providing the following facilities:

(1) The ability to collect Extended Floating Car Data (XFCD) from the host Vehicle and the Other Vehicle plus fused data from the System that it has collected from other Vehicles.
(2) The ability to collate and fuse all of the data that has been collected to provide a coherent and consistent view of the road and traffic situation around the host Vehicle.
(3) The ability to send the data that has been collated and fused to the Driver Display Function.

Functional Requirements

(a) continuously monitor for the receipt of the input data flows
(b) when any of the data flows in (a) is received, combine and fuse its contents to form a coherent and consistent set of traffic and road data for the area surrounding the host Vehicle
(c) as part of (b) reject data from the Other Vehicle or from other system functionality if it is about a location, or about traffic that is travelling in a direction that is not relevant to the host Vehicle
(d) store the results of the processing in (b) and (c) locally for use in (b) when either of the data flows in (a) is received again
(e) send the results of (b) and (c) to the Display function.
