Abstract

In the event of an accident or another traumatic event to a vehicle, a wireless vehicle location and emergency notification system is provided for determining the location and sensing the condition of a vehicle, comparing this information to established parameters, and transmitting such information to a base station in the event the sensed condition or determined location is outside the established parameters. The base station may then alert local emergency services if necessary. The system utilizes a global positioning receiver for determining the location of the vehicle and sensors for monitoring vehicle conditions such as vehicle attitude, deceleration, shock, temperature and passenger compartment audio. The location and condition information is communicated to a data processor which compares this data to established parameters and recently stored location and condition data. If the location and/or condition information fall outside the established parameters or the new data does not compare with the recently stored data, a transmission is sent to the base station. This information is also communicated to a user interface unit, usually within the passenger compartment, which has a display, keypad, and speaker/microphone. The system operates continuously and without the need for user intervention.
