    • 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.

    • A low speed region position estimating portion 41 is designed to be suitable for when the motor is operating in a low speed region, and estimates a low speed estimated rotational position θ^ L . A high speed region position estimating portion 42 is designed to be suitable for when the motor is operating in a high speed region, and estimates a high speed estimated rotational position θ^ H . A dividing portion 43 obtains a divided estimated rotational position θ^ M by internally dividing the low speed estimated rotational position θ^ L and the high speed estimated rotational position θ^ H . A rotation speed calculating portion 24 obtains a rotation speed ω of a rotor based on an output signal from a steering sensor 4. The rotational position of the rotor is then obtained by selecting one of i) the low speed estimated rotational position θ^ L , the high speed estimated rotational position θ^ H , or the divided estimated rotational position θ^ M , based on that rotation speed ω.
