Data recorded by vehicle-mounted electronic control units (ECUs) are highly useful in traffic accident reconstruction. In this context, event data recorders (EDRs) are airbag ECU components used to log information from crash events, typically providing data on speed, accelerator operation, RPMs and brake lamp activation for a period of around 5 s before a collision. ...Thus, it is important to check the accuracy of EDR speed data in accident reconstruction. Meanwhile, pre-crash safety systems (PCSs) are also becoming more widespread in automobile usage today. ...Such systems automatically apply braking in hazardous situations, and the relevant data recorded in the ECU are promising in the field of accident reconstruction. This study involved physical tests in the form of simulated rear-end collisions and the collection of recorded PCS data at the post-test stage.
