System and method for automatic traffic accident determination and notification
First Claim
1. An accident detection device for automatically detecting vehicular accidents and providing accident notification, the accident detection device comprising:
- an integral housing comprising a plug configured for coupling to a power source socket associated with any one of a plurality of vehicles, said housing positioned in a fixed manner relative to the vehicle when coupled thereto;
an energy storage device residing within the housing;
a power supply residing within the housing and configured to receive power from the power source when the housing is coupled to the power source socket, and further to receive power from the energy storage device when the housing is detached from the power source socket;
one or more movement sensors residing within the housing and effective to generate output signals associated with movement of the vehicle;
a position sensor residing within the housing and effective to generate output signals associated with a position of the vehicle;
a communications device residing within the housing and effective to send and receive data via a communications network; and
a control unit residing within the housing and functionally linked to each of said power supply, movement sensors, position sensor and communications device and further comprising a processor and one or more memory media, at least one of said memory media having program instructions residing thereon which upon execution by the processor are further effective toreceive and store accident threshold settings comprising an acceleration threshold and a velocity threshold sent via the communications device,determine a location of the vehicle based on the position sensor output signals,upon receiving input power from the power source, to begin continuously receiving acceleration and velocity data as the output signals from the one or more movement sensors;
compare the acceleration data to the acceleration threshold and compare the velocity data to the velocity threshold;
detect removal of the accident detection device from the power source socket;
determine a movement status of the vehicle including a potential accident condition indicating whether the removal of the accident detection device from the power source socket was a forcible ejection due to an accident, based on the comparison of the acceleration data and the velocity data to the respective thresholds, andtransmit one or more of said vehicle location and movement status via the communications device to a predetermined emergency contact upon determining a movement status associated with an accident.

Abstract
A vehicle status awareness system includes one or more devices which are plugged into a cigarette lighter socket for a vehicle to receive power and are thereby fixed in position relative to the vehicle. The devices include movement sensors which indicate changes in movement of the vehicle, a position sensor which indicates a position of the vehicle, a communications device to send and receive data to and from a remote device, and a control unit. The control unit is programmed to receive and store program parameters, determine a location of the vehicle, determine a movement status of the vehicle based on a plurality of status criteria further comprising accident threshold settings, and transmit one or more of the program parameters, vehicle location, and movement status to the remote device. Where multiple devices are included, each device may have an RF transceiver or equivalent for bidirectional communications with the other device.
