Claim Text:
1. A control apparatus for a rotary electric machine of a vehicle, the vehicle being equipped with a drivetrain that includes a transmission for transmitting power output from rotation of a rotating member of the rotary electric machine to driving wheels according to a variable speed change ratio, the control apparatus comprising: an extractor that extracts, from a rotational speed of the rotating member, a vibration component included in the rotational speed of the rotating member, the vibration component being based on vibrations of the drivetrain; a compensation torque calculator that calculates, according to the vibration component extracted by the extractor, compensation torque that compensates for the vibrations of the drivetrain; a controller that performs drive control of the rotary electric machine according to the compensation torque; a first suppressor that performs first suppression to suppress the rotational speed of the rotating member from changing due to change of the speed change ratio; a mode setter that switchably sets one of an enabling mode to enable the first suppression or a disabling mode to disable the first suppression in the control apparatus according to a parameter indicative of the speed change ratio; and a second suppressor that performs second suppression to suppress change of the vibration component generated based on switching of one of the enabling mode and the disabling mode to the other thereof.
