Abstract
A vehicle collision warning system 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 sound 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 object, and voice commands. The sounds are stored monaurally and are converted to directional sounds using known techniques.
