First Claim
1. A system, comprising:
- a user interface for providing information to and receiving information from a user of a vehicle, the user interface including either a touch display or a keypad and a display, and the vehicle including one or more sensors for sensing location and velocity of the vehicle, wherein the one or more sensors include a sensor for detecting an emergency condition;
a short range transmitter for direct wireless broadcast of data regarding a sensed location and velocity of the vehicle without engaging a public wireless mobile communications network;
a short range receiver for direct wireless reception of wirelessly broadcast data regarding location and velocity of any other vehicle within a short range of the vehicle without engaging the public wireless mobile communications network;
a network access device of a telematics unit including a wireless transceiver for wireless cellular communication via the public wireless mobile communications network for communication with a call center of a telematics service provider; and
a control unit, responsive to a detected emergency condition to control the network access device of the telematics unit to report a detected emergency condition through the public wireless mobile communications network to the call center and responsive to the one or more sensors and the short range receiver, for controlling information output for the user via the user interface,wherein the control unit also is configured to;
receive, from the user via the keypad or the touch display of the user interface, a selection of a collision hazard criteria from among a plurality of collision hazard criteria,when data is directly received from a plurality of other vehicles within the short range of the vehicle without engaging the public wireless mobile communications network, select another vehicle from among the plurality of other vehicles based on the user-selected collision hazard criteria,process the sensed location and the velocity of the vehicle and the received data regarding location and velocity of the selected other vehicle to detect a collision hazard relative to the selected other vehicle and detect one of a plurality of levels of risk of collision relative to the selected other vehicle, andresponsive to detecting one of the plurality of levels of risk of collision, cause the user interface to output a hazard alert indicating a detected level of risk of collision relative to the selected other vehicle.

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.
