A black box is a term typically used to describe a device which is unknown or hidden from the user. In the automotive industry black boxes are typically used to refer to event data recorders (EDRs). EDRs are devices that are installed in vehicles to record information about the vehicle and its occupants during a crash. This information can be used to help determine the cause of the crash and improve vehicle safety.
Event data recorders were first introduced in the early 1990s and are now required by law in many jurisdictions. They are typically mounted in the engine compartment or under the floor of the vehicle. The data recorded by the EDR includes information such as the vehicle speed throttle position brake application airbag deployment and seatbelt use. This data can be invaluable in understanding what happened during a crash and can be used to improve vehicle safety.
EDRs are not able to record every aspect of a crash but they can provide valuable information that can help investigators understand what happened. Additionally EDR data can be used to improve vehicle safety features and help prevent future crashes.
