A vehicle collision warning system (10) converts collision threat messages from a predictive collision sensor into intuitive sounds which are perceived by the occupant to be directed from the direction of the potential collision. The type and volume of the sounds are dependent upon the estimated likelihood, severity, and commencement time of the collision. The types of sounds are chosen to evoke the proper corrective action by the driver as necessary to avoid the collision or mitigate the effects thereof. Examples of the sounds include a horn, screeching tires, a siren, sounds of various types of vehicles and objects, and voice commands. The sounds are stored monaurally and are converted to directional sounds using known techniques.

L'invention concerne un système (10) d'alerte de collision de véhicules permettant de convertir des messages de danger de collision provenant d'un capteur prédictif de collision en des sons intuitifs qui sont perçus par l'occupant comme provenant du côté de la collision potentielle. Le type et le volume des sons dépendent de la probabilité, de la gravité estimées de la collision et du moment estimé où celle-ci débuterait. Les types de sons sont choisis en vue d'évoquer l'action correctrice adéquate que le conducteur doit effectuer pour éviter la collision, ou réduire les effets de celle-ci. Des exemples de sons comprennent notamment un coup de klaxon, des pneus qui crissent, une sirène, des sons de divers types de véhicules et d'objets, et des instructions vocales. Les sons sont enregistrés de façon monophonique et sont convertis en sons directionnels à l'aide de techniques connues.
