<p>A control apparatus and method for controlling an electric rotating machine for vehicle reduces shock at the time of switching power generation mode. The control apparatus include an electric rotating machine functioning as a starter motor and a charging generator 1, an inverter comprised of switching elements 14 to 19, a field current controller 5 for controlling an electric current of a field coil 4 of the electric rotating machine 1, and a controller 24 by which power is generated in an inverter generation mode in a low-speed rotation range and in an alternator generation mode in a high-speed rotation range. A hysteresis is established between a rotating speed in switching from the inverter generation mode to the alternator generation mode and a rotating speed in switching from the alternator generation mode to the inverter generation mode under the control of the controller 24.</p> |
