<P>PROBLEM TO BE SOLVED: To provide a motor controller, can perform drive control of a drive motor even if torque transmission between an engine and the drive motor is interrupted. <P>SOLUTION: The motor controller estimates a rotating state of the drive motor 3 without acquiring the rotating speed of the drive motor 3 to drive-control the drive motor 3 so as to reach a predetermined operation point, thereafter compares the estimated rotating state with a rotation signal from a rotation detection sensor for detecting the rotating speed of a rotating shaft or an engine 1 or a transmission 5 which is laid in a connecting state with the drive motor 3 by a clutch to learn a phase difference related to the rotating state of the drive motor 3, and controls drive of the drive motor 3 by use of the rotation signal from the rotation detection sensor. <P>COPYRIGHT: (C)2009,JPO&INPIT |
