GM Adds Advanced Automatic Crash Notification to OnStar Service

In an effort to help 911 centers dispatch the appropriate life-saving staff and equipment to crash scenes faster, General Motors will begin adding an advanced automatic crash notification (AACN) system to vehicles equipped with OnStar.

Currently, OnStar, an embedded in-vehicle safety and security communications system, is automatically notified within seconds when a subscriber's air bag deploys. The next-generation GM automatic crash notification system will use a collection of strategically located sensors to automatically call for help if the vehicle is involved in a moderate to severe frontal, rear or side-impact crash, regardless of air bag deployment. Also, the new system provides crash severity information to OnStar call center advisors, who relay it to 911 dispatchers, helping them to quickly determine the appropriate combination of emergency personnel, equipment and medical facilities needed.

When the AACN system is triggered by a crash of sufficient severity, an emergency voice/data connection will be established with an OnStar call center. The advisor will use the voice channel in the vehicle to communicate with the crash victims and, at the same time, conference-in the nearest public service answering point (911 dispatcher) and provide specific data about the severity of the crash. The 911 dispatcher can then inform emergency responders of the data. In the future, AACN data may be transmitted electronically to the 911 centers, emergency responders, emergency departments and trauma centers using secured Internet connections.

Eventually, the system may be capable of determining how many occupants are in the vehicle, whether they are using safety belts and other information that helps emergency responders further anticipate the types and severity of injuries that may have occurred in a crash. The GM AACN system will be available beginning in 2003 on about 400,000 OnStar-equipped 2004 model year vehicles, including the Chevrolet Malibu, Chevrolet Trailblazer, GMC Envoy and Envoy XUT, Oldsmobile Bravada and the Buick Rainier. AACN will be added to additional GM model lines equipped with OnStar in subsequent model years. The system will be rolled out into vehicles sold in the U.S. and Canada.
