WILLWARN


 

Foresighted driving and early detection of hazards is a key for safe driving and accident avoidance. WILLWARN (Wireless Local Danger Warning) is developing a communication-based system that extends the driver's horizon and intelligently warns the driver of dangerous situations ahead. WILLWARN provides drivers the opportunity to adapt the vehicle speed and inter-vehicle distance early-on, leading to a higher situational awareness of potential unforeseen danger.

 

 

Objectives

The three-year WILLWARN subproject is developing, integrating and validating a safety application that warns the driver whenever a safety-related critical situation occuring beyond the driver's field of view. This includes the development of on-board hazard detection, in-car warning management, and decentralised warning distribution by vehicle-to-vehicle communication on a road network. Positioning, relevance checks, message transport, and on-board message evaluation will enable a low-cost and reliable solution for wireless local danger warnings.     

 

Key Concepts

The key issues of WILLWARN include:

  • Improved safety through vehicle-to-vehicle and vehicle-to-infrastructure communication
  • High benefit for the user even at low equipment rates using cars as relays for transporting messages in a road network
  • Design of a basic system at low cost  

WILLWARN will cover the following scenarios:

  • Detection and warning of obstacles on the road, warning if one's own car is an obstacle for others
  • Warning of emergency vehicles or slow vehicles
  • Detection of reduced friction or reduced visibility through bad weather
  • Warning of dangerous spots such as construction zones through electronic beacons      

 

 

 

Key Events and Milestones

WILLWARN has four major milestones at the IP level:

  • Functional requirements and basic design decisions (January 2005)
  • System Specification (July 2005)
  • Experimental setup & test equipment (July 2006)
  • Validation, evaluation and assessment (January 2007)

 

Application of Results

WILLWARN contributes to the IP PReVENT functions hazard messaging and warning, and electronic horizon, and enables foresighted driving. A major result will be the functional system design of the wireless local danger warning application with the following components:

  • Hazard detection algorithms (logics and observers) based on CAN data, GPS, and optional environment sensors e.g. radar
  • Warning Message Management with messaging and forwarding strategies
  • On-board relevance checks and warning evaluation
  • Communication requirements, choice of radios, frequency allocation, and standardisation. System architecture and protocols for routing and application
  • Guidelines for Human Machine Interface
