Beschreibung
Zusammenfassung:	A vehicle control apparatus is provided with: a modulator configured to generate modulation signals; a first corrector configured to perform a first correction process in which a center value of the modulation signals is corrected to reduce a loss in the inverter; a second corrector configured to perform a second correction process in which an amplitude shift and a phase shift of the third harmonic signal with respect to the voltage command signals are reduced; and a controller configured (i) to control the first corrector to perform the first correction process if the DC voltage is greater than or equal to first predetermined voltage and (ii) to control the second corrector to perform the second correction process if the DC voltage is less than the first predetermined voltage, when a number of revolutions of the AC motor is less than a predetermined number of revolutions.
