Due to significant limitations however, EDR data should always be used in conjunction with other data sources. NHTSA estimates manufacturer cost to comply with the regulations will be about 17 cents per car. Read Consumers Union calls for changes to strengthen U. Consumers Union , the advocacy arm of Consumer Reports, has supported standardizing black-box data , so accident investigators can use it to improve the safety of future vehicles and crashes.
We've spoken to trauma centers that say that the data, in individual cases, would be invaluable in diagnosing injuries of the accident victims. But we also believe that the owners of the cars should own the data, and we have concerns over the privacy implications of its use. Overall, the NHTSA rule is a strong step forward in improving auto safety, one in line with our recommendations for improving U.

Our goal is to provide a voice for this silent witness by providing relevant vehicle data that shows the true events of a crash. The event data recorder logs vehicle data seconds before and seconds after a possible event.
An event is usually detected by excessive deceleration of the vehicle. This does not necessarily have to be an accident. An event could also be harsh deceleration or harsh braking.

There are 9 mandatory data elements, each with a minimum sampling rate and a standardised format. These include speed of the vehicle, whether the brakes were applied, the engine throttle and seatbelt status.
However, there are many more elements that could potentially be recorded. Making sure we have all this information early on avoids duplication of effort and minimises the need for assumptions. In the long run this saves you time and money, as well as getting you the best results. In general terms, if the airbags deploy i. However, it is possible for the pre-determined thresholds to be exceeded without the airbags deploying i.
In this case, data will still be recorded. For a deployment event, the data is locked and cannot be overwritten — therefore, there is no time limit. This is one of the biggest problem areas when it comes to EDR data. Federal Regulations give strict requirements in relation to what the data must contain, how long it records for and how it is accessed. Currently in the EU there are no requirements, which means that even though data is recorded, it is not accessible.
However, as part of the update to the General Safety Regulations, in all new vehicles must have an EDR fitted and allow the EDR data to be accessed — though only for road safety research purposes. Data ownership is a common problem area and, unfortunately, EDRs are no different.
