Abstract
An in-vehicle controller of the invention is a so-called drive recorder. The drive recorder is incorporated in a steering ECU (controller) 10. For this purpose, the controller 10 is provided with function implementation units which includes a memory 22 as a data logging section, a memory controlling section 23, a threshold judging section 24 and a data-transfer timing output section 25. Vehicle information and steering information are stored in a first memory 221 in chronological order. A second memory 222 logs data recorded in a tens-second period before and after a moment when vehicle acceleration exceeds a predetermined threshold. The information logged by the second memory 222 is transferred to a hard disk of a navigation unit 30 in a predetermined timing.
