6.7.1.3: Process Vehicle Location Data
This process shall provide the vehicle's current location to other processes within the vehicle. It shall receive the precise location from a Location and Time Data Source terminator. The terminator may base its data on one or more sources of position data such as GPS, DGPS, odometer and differential odometers, and may refine its calculations using techniques such as map matching, etc. This process shall then read the map database stored on-board and be able to provide a process location of which road and, depending on the accuracy of the location data source which lane on that road the vehicle is. This process shall then provide that location data to other processes for guidance, advisories, probe data, collision avoidance, and emergency/incident detection.
This process is associated with the Vehicle OBE physical object.
