Abstract

As modern vehicles converge with information and communication technology (ICT), an increasing number of software packages are being installed in vehicles. The software can generate an audit log whenever an event occurs, and by using this, the condition of the vehicle can be understood easily. However, vehicle forensics is not well established in the automotive industry. In particular, it is difficult to properly understand the situation at the time of a crime using a vehicle or a traffic accident. Vehicles are obliged to be equipped with events and data recorders (EDRs) to infer certain situations, but there can be difficulties in interpreting data when the vehicle does not use a standardized protocol, or to the method of acquisition of data in non-canonical situations has not yet been systematically processed. In this study, we have proposed a systematic data acquisition and analysis method for the EDR. We demonstrated the efficiency of our proposed method through experiments on mass-production vehicles.
