摘要

A device (1) to be installed on board vehicles, designed for automatic detection of road accidents and of the modalities with which a vehicle is driven and for storage of the data detected, comprises: first means (3), designed to measure the six components of acceleration (ax, ay, az, alphax, alphay, alphaz) of said vehicles; and second means (4), provided with absolute-time reference, for processing and storing the data supplied by said first means (3); said accidents being detected when the combination of said six components of acceleration (ax, ay, az, alphax, alphay, alphaz), or their resultant, present characteristics of value and progression that are not compatible with the technical characteristics of said vehicles. A method for detecting road accidents undergone by vehicles envisaged direct detection of the six components of acceleration (ax, ay, az, alphax, alphay, alphaz) of said vehicles, said accidents being detected when the combination of said six components of acceleration (ax, ay, az, alphax, alphay, alphaz), or their resultant, present characteristics of value and progression that are not compatible with the technical characteristics of said vehicles.
