Foresighted driving and early detection of hazards is a
key for safe driving. WILLWARN (Wireless Local Danger Warning) is a communication
based system that supports the driver in safe driving through warnings
and foresighted information.
Within the PReVENT Integrated Project, the three-year
WILLWARN vertical subproject develops a system for on-board hazard detection,
in-car warning management, and decentralised warning distribution by communication
between vehicles on a road network. Positioning, relevance checks, message
transport, and onboard message evaluation will enable a high benefit for
the driver even at low equipment rates.
WILLWARN focuses on the following challenges:
through car to car and car to infrastructure communication
for the user even at low equipment rates using cars as relays for transporting
messages in a road network

WILLWARN will cover different scenarios in order
to validate the concept:
warning of obstacles on the road, warning if the own car is an
obstacle for others
emergency vehicles or slow vehicles
reduced friction or reduced visibility through bad weather
dangerous spots like construction zones through electronic beacons
Events and Milestones
The WILLWARN subproject has four milestones
at the IP level:
requirements and basic design decisions (Jan. 2005)
setup & test equipment (July 2006)
evaluation and assessment (Jan. 2007)
The picture below shows how the milestones contribute to IP level.
