Advanced Automatic Collision Notification
Encyclopedia
Advanced Automatic Collision Notification (AACN) is also known as Advanced Automatic Crash Notification and is the successor to Automatic Collision Notification (ACN). This system is found on a number of motor vehicle
s and is used to alert emergency service
s that a crash has occurred and to automatically summon assistance.
When a crash has occurred (as determined by various sensors, airbag deployment
, or seatbelt pretensioners), the AACN will initiate an emergency wireless call to a Telematics
Service Provider (like Onstar
) to deliver the vehicle's GPS location, crash-related data and open a voice communications channel to the emergency call center.
The Advanced ACN improves the data sent from the ACN version, as it include crash-severity data (including: speed, delta velocity, number of occupants and rollover data) as collected by in-vehicle sensors. This additional data could be used by emergency services providers to determine the quantity and type of rescue equipment that should be dispatched.
initiative will enable a Public Safety Answering Point to automatically receive and process this data, thereby allowing for a quicker and more efficient response to a vehicle emergency, even when all occupants of the reporting vehicle are incapacitated.
Motor vehicle
A motor vehicle or road vehicle is a self-propelled wheeled vehicle that does not operate on rails, such as trains or trolleys. The vehicle propulsion is provided by an engine or motor, usually by an internal combustion engine, or an electric motor, or some combination of the two, such as hybrid...

Vehicular Emergency Data Set (VEDS)
The Vehicular Emergency Data Set is an XML-based standard for reporting collision data elements and medical data elements related to a collision. The standard was developed by the ComCARE Alliance, and is aimed at relaying critical information to facilitate efficient emergency response. This data set can be transmitted automatically to a response center, which can then forward it to emergency services providers. In the U.S., the Next Generation 9-1-1Next Generation 9-1-1
