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.




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:

WILLWARN will cover the following scenarios:




Key Events and Milestones

WILLWARN has four major milestones at the IP level:


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:
