EVU XXV 2016 – 03 Experience with Data Readout from the Event Data Recorder (EDR)
Experience with Data Readout from the
Event Data Recorder (EDR)
Because of the electronic systems in our vehicles, the Active and Passive Si safety could be increased
enormously. These significant advantages also have disadvantages. The last are reduction or loose of
objective measures like traces on the road that might allow the traffic accident experts in their role as
helpers of the investigating authorities, courts and insurance companies to assess the Pre Crash Phase.
The problem is well known. To overcome this lag, in the USA electronic data storages have been developed since about 1994. At the first years, the industry was focused on the crash phase. Since about
2009, the first 5 s before the accident the most important data such as speed and other driving data
are recorded. In addition accident-relevant information about the vehicle occupant, such as the seat
occupancy status of the seat belts, etc are recorded. In the US, the current market coverage for new
cars is currently 99%, 1 % is still without EDR.
If the vehicle manufacturers in the USA and Canada want to bring new models into the market, this models must have an Event Data Recorder (EDR) and the data must be retrievable with a publicly available tool.
The possibility of data storage and the readout becomes more and more urgent because the-introduction
of the semi-autonomous driving of vehicles objective data is essential for assessing the causes of
accidents. When we think about autonomous driving, the problem becomes even more apparent.
In the opinion of the author, the readout of accident related data must be primarily done by the investigating authorities (Police), and there must be specialized experts for accident reconstruction, who will be able to assess this data correctly.
