PASSENGER VEHICLE BLACK BOX DOWNLOADS

Passenger vehicles have evolved into very sophisticated machines which utilize multiple computerized systems to ensure the vehicle operates correctly.  Modern vehicles are equipped with multiple computer systems which monitor and control various systems such as airbags and passenger restraint systems, traction and stability control systems, anti-lock brake systems and engine control systems. Recently, Federal regulation CFR 49 part 563 mandates that every passenger car and truck manufactured after September 1, 2012 (with some limited exceptions), make pre-crash data accessible using commercially available equipment.  However, for vehicles manufactured prior to September 1, 2012, only select manufactures have elected to make pre-crash data available for download.

Most vehicles on the road today contain a “black box”. A black box is a common term for many different data recording devices located on a vehicle.

 

Depending on the specific vehicle, black box recorded data can include:

  • Vehicle speed

  • Brake application

  • Throttle application

  • Steering inputs

  • Seat-belt usage (for front occupants)

  • Impact related delta-V (impact severity)

Additionally, some of this data may be captured even if the airbags were not deployed in the accident. Contact us for more information on your specific vehicle or click on the links below for information on passenger vehicle black boxes and commercial vehicle black boxes.

COMMERCIAL VEHICLE EVENT DATA RECORDER DOWNLOADS

The engine control modules (ECM) utilized in most commercial vehicles have the ability to record and store potentially valuable pre-crash information.  While downloading a truck’s ECM may provide information related to the vehicle’s speed, braking and other parameters prior to an accident, it is important to understand that the ECM was not designed as a data recording device for accident reconstructionists. Rather, it’s primary purpose is for the management of engine functions. As such, the extraction and interpretation of data from an ECM requires substantial knowledge and experience in order to avoid some of the common errors associated with these recording devices.  

Veritech engineers are trained and experienced at interpreting and understanding the vast amount of data contained in an ECM report and we can help guide you as to which reports may contain valuable information.
