What is an Event Data Recorder?
An Event Data Recorder (EDR) is part of a vehicle's electronic system
and is sometimes referred to as an airplane's
"black box". It always keeps track of a window of information concerning the vehicle operation, such as the speed,
throttle position, airbag, and brake application. An event, for example, a crash or an abrupt braking, it is
forwards the EDR to collect the data of the moments before, during and after the event.
Event Data Recorder Vehicle List
EDRs have become increasingly common in modern vehicles, being standard in most new cars sold in the United States.
Notable manufacturers include Ford, Toyota, General Motors, and more. In order to ascertain if your particular
vehicle model has an EDR, you can review your vehicle's owner manual, or contact the manufacturer.
The "event data recorder vehicle list" is not complete as it is (though some countries have made EDRs mandatory on
all new vehicles for vehicle manufacturers) not a global requirement. However, according to the U.S. National
Highway Traffic Safety Administration (NHTSA), as of 2014, 96% of all new vehicles sold in the U.S. are equipped
with an EDR.
What Does an Event Data Recorder Record?
In vehicles, an Event Data Recorder (EDR) operates as a black box and records vital information for the duration of
a drive, especially during an accident. This information is highly valuable for road incident analysis and has been
applied to improve vehicle safety, in legal proceedings and for insurance claims.
The vehicle's event data recorder captures these data points:
Vehicle Speed: Keeps track of the speed of the vehicle at all times.
Steering Angle: Monitors the precise steering wheel angle.
Brake Activation: Indicates when and how strongly the brakes are applied.
Airbag Deployment: Documents when and how robustly the airbag deploys.
Status of Seat Belts: Shows if seat belts were in use.
Engine RPM: Tracks the engine's rotating rotations per minute.
Throttle Position: Describes where the throttle is located on all occasions.
G-Force Measurements: Record the forces of gravity applied at any given time.
GPS Data :
Crash Impact Data: Defines the collision's impact size and direction.
Does My Car Have an Event Data Recorder?
To address the question, "Does my car have an event data recorder?"" It is advisable to refer to the manual of the
vehicle you own. Generally, whether or not your vehicle owns an EDR is stated explicitly. There are also ways to
look for presence of EDR using OBD2 scanner if technical
expertise is available.
The EDR location may differ depending on the manufacturer or model, but they generally are integrated with the
airbag controller module because of common interest in data related to vehicular crashes.
EDR: An Essential Tool for Vehicle Safety
To conclude, EDRs play an important function in improving vehicle safety. They offer relevant understandings of the
seconds just before, during, and after a crash, therefor, making it easier for investigators to come up with the
sequence of events and for the development of vehicle safety devices.
As an automobile owner, it is important to be sure that your automobile possesses an EDR, as this information may
also be informative in attempting to adjudicate insurance claims and civil liabilities pertaining to automobile
collisions. It is an added dimension of safety and comfort in our always connected vehicle world.
Remember, while this glossary serves as a beginner's guide, consulting with a professional for further clarification
about the specifics of your vehicle's systems is always recommended.
