  • Patent number: 6819234
    Abstract: Method and system for providing an audible warning of approach of a moving vehicle that is undergoing hard braking. When hard braking is being applied and the initial vehicle velocity (just before hard braking is first applied) is at least equal to a selected threshold velocity, an artificially produced warning sound, resembling the screech or howl of one or more tires in a panic stop, is transmitted, in one or more selected angular sectors. If the initial vehicle velocity is less than the threshold velocity, the warning sound is witheld. The threshold velocity may depend upon one or more of initial velocity, initial deceleration, local road surface conditions and local weather conditions.
