Collision avoidance system using telematics unit

Abstract

The various examples disclosed herein relate to systems, methods, and equipment that provide location and velocity monitoring of both a user's vehicle and another vehicle to avoid collision. The examples are applicable for using on-board telematics units to process that information and provide additional information based thereon such as the probability of collision. In some examples, if the chances of collision are high based on information received, warnings may be given to the vehicle's user. Based on these warnings, the user may take evasive maneuvers to reduce the probability of collision and prevent it. In other examples, if the chances of collision are high, the vehicle may decelerate without prompting from the user to minimize the impact of the collision. Any emergency reporting by the telematics unit, e.g. if a collision still occurred, may be enhanced with the relative location and velocity data from some interval the prior to emergency.
