<P>PROBLEM TO BE SOLVED: To control an electric motor more appropriately. <P>SOLUTION: An ideal angle after correction θidmo obtained by correcting an ideal angle θid from a converter 34 with the use of a rotational angle change amount during conversion Δθofs, which is larger if the number of rotation Nm of a motor 10 is larger, is used for switching control of a switching element of an inverter 12. Thus, the ideal angle θid input to an electronic control unit 40 can be converted to an ideal angle corresponding to a detection angle θdet output from a resolver device 22 at that timing, and the motor 10 can be more appropriately controlled for driving. <P>COPYRIGHT: (C)2012,JPO&INPIT |
