Abstract
In order to make it more difficult to alter the recorded data in an event data recorder, a plurality of electric control devices may each have a memory device and may each play a respective role in the vehicle. A data assignment device may be connected to the plurality of electric control devices and the data assignment device may assign a part of drive record data to one of the plurality of electric control devices to store the part of drive record data. The data assignment device may also assign the rest of the drive record data to the rest of the plurality of electric control devices to store the rest of the drive record data.
