D22.31 Functional system design


WILLWARN

 

Confidential document

 

Technical Abstract
This document describes the potential applications, the selected scenarios and the requirements of the proposed Wireless Local Danger Warning system, through a general functional overview. WILLWARN contributes to the PReVENT functions hazard messaging and warning, contributes to the electronic horizon, and enables foresighted driving. It mainly aims at improving driving safety through car to car and car to infrastructure communication while focusing on the design of a basic system at low cost.
The work reported herein was organized in two main stages. Initially all potential hazards/endangerments were collected. Following this, all WILLWARN applications were defined and classified in a form of a detailed Hazard Matrix in four categories:

  • Obstacles (Own car as obstacle, Detected obstacles)
  • Reduced friction (Heavy rain, Snow and ice)
  • Reduced visibility (Rain and snow, Fog)
  • Others (Construction sites, Emergency vehicles)

The Hazard Matrix comprises all endangerments, sensor and CAN-data, with the rows and columns defining the various hazard types and all commercially available sensors and corresponding sensor data, respectively.
During the second stage, all WILLWARN applications were determined, taking into account the information described in the Hazard Matrix concerning detection of dangers through sensors and CAN-Data.
The intention of WILLWARN is not to produce a commercial foresighted driving product but to provide a guideline for vendors and automobile industry to follow. Therefore full interoperability between different vendors various modules is expected. The WILLWARN system is divided into four discrete modules, specifically VVC (Vehicle to Vehicle Communication), HWM (Hazard Warning Module), HDM (Hazard Detection Module) and WMM (Message Management Module), and each module requirements and functionality are reported in the current deliverable.
