Overview

This Function shall be capable of providing the following facilities:

(1) The ability to take responsibility for processing information from sensors that detect the atmospheric conditions near to the Host Vehicle, i.e. the Vehicle in which it is operating.
(2) The ability to process the sensor data to determine such things as temperature, wind strength and direction (taking account of the Host Vehicle's direction of travel), the presence of rain, etc.
(3) Once processing is complete, the ability to send the data in digital form to the Determine and store local Host Vehicle Conditions Function.

Functional Requirements

(a) continuously monitor the flow of input data
(b) analyse the data in (a) to determine the atmospheric conditions that are local to the host vehicle, such as temperature, wind strength and direction (taking account of the host vehicle's direction of travel), the presence of rain, etc.
(c) if necessary convert the results from (b) into digital data
(d) whenever the atmospheric conditions change and/or at other intervals, send the results of (c) to the Determine and store local Host Vehicle conditions function in the data flow containing local vehicle environment data.
