Abstract

In an apparatus for controlling a motorized vehicle equipped with a rechargeable battery, a rotary electric machine electrically connected to the rechargeable battery, and electrical loads electrically connected to the rechargeable battery, a machine operating point setter is configured to, when current is passing between the rechargeable battery and the rotary electric machine, set operating points of the rotary electric machine, each specifying a system efficiency representing a ratio of input/output dynamical power of the rotary electric machine to input/output power of the rechargeable battery, a torque of the rotary electric machine, and a rotational speed of the rotary electric machine that are taken as parameters, based on the amount of current flowing through the rechargeable battery. A rotary electric machine controller is configured to control the rotary electric machine to operate at the operating points of the rotary electric machine set by the machine operating point setter.
