Digital Vehicle Data Recorder (DVDR)
Dr. Ravi Kumar (Sr. Scientist –Earthbotics (Embedded Division))
A Vehicle data recorder or VDR is a device installed in automobiles to record information related to vehicle crashes or accidents. Information from these devices can be collected after a crash and analyzed to help determine what the vehicles were doing before, during and after the crash or event. The term generally refers to a simple, tamper-proof, read-write memory device, similar to the “black box” found on airplanes. VDR may record a wide range of data elements, potentially including whether the brakes were applied, the speed at the time of impact, the steering angle, and whether seat belt circuits were shown as “Buckled” or “Unbuckled” at the time of the crash.
