<P>PROBLEM TO BE SOLVED: To provide a control device which can continue the control of a motor for a vehicle even if a polarity position sensor fails. <P>SOLUTION: A detected value of a polarity position is corrected to an advanced angle side in the case that a detection resolution of the polarity position is deteriorated due to an abnormality of the polarity position sensor and the polarity position is included in an angular region in which the detection resolution is deteriorated. By this, even if an abnormality that the resolution of the polarity position is deteriorated is generated, rotation control can be continued by correcting the detected value to the advanced angle side in the angular region in which the resolution is deteriorated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
