Abstract
An electronic control unit switches a switching circuit such that a switched reluctance motor has a first winding pattern, when, with respect to a boundary dividing a driving range of the switched reluctance motor into two ranges, a torque and a rotational speed of the switched reluctance motor that are determined according to an applied voltage are located in the first range on the low load side. The electronic control unit switches the switching circuit such that the switched reluctance motor has a second winding pattern, when the torque and the rotational speed of the switched reluctance motor are located in a second range different from the first range.
