Device for warning road traffic users about jams and accidents uses a positioning device on a motor vehicle for generating an optical warning signal like a warning balloon.

摘要

A first motor vehicle (FMV) (10) collides e.g. with a second motor vehicle (SMV) (15) on a bend. A sensor unit uses the FMV impact on the SMV to recognize the collision through sensors for bodywork data and to transmit a collision signal to a pressurized gas valve to make it open and release gas to inflate a warning balloon (2) attached to a line (8) to warn other oncoming vehicles (16,17).
