DFD 5.15.1 Provide Detection for the Vehicle Surroundings

Overview

This High-level Function provides facilities for the detection of what is happening in vicinity of the Host Vehicle.  It contains functionality that can detect Other Vehicles, Other Road Users, Pedestrians, atmospheric conditions, visibility, road surface state and stationary objects.  The data produced by the detection functionality is sent to other functionality for storage and analysis.
