Abstract: In an apparatus for controlling a motorized vehicle, a rotary electric machine controller is configured to perform intermittent operation by periodically alternating between a driving period and a coasting period. A torque determiner is configured to determine a first torque during the driving period and a second torque during the coasting period. A transition period determiner is configured to determine whether to set a transition period between the driving period and the coasting period. If the transition period is determined to be set, the torque determiner determines a third torque between the first torque and the second torque and within a predetermined rang. The rotary electric machine controller sets the transition period between the driving period and the coasting period and drive the rotary electric machine with the third torque during the transition period.

Abstract: In an apparatus for controlling a motorized vehicle equipped with a main rechargeable battery, electrical loads electrically connected to the main rechargeable battery via a voltage converter, a converter operating point setter is configured to, when current is passing between the main rechargeable battery and the electrical loads, based on a charging/discharging amount of the main rechargeable battery, set operating points of the voltage converter, each specifying a power conversion efficiency representing a ratio of input power to the electrical loads to output power of the main rechargeable battery and an output current of the voltage converter. A converter controller is configured to, based on the operating point set by the converter operating point setter, cause the voltage converter to convert the voltage of the main rechargeable battery, thereby supplying power to the electrical loads.
