Abstract:
1. A control apparatus for an electric vehicle comprising: a power conversion means that converts a voltage supplied by a DC power supply into a system voltage appearing on a power supply line; an MG unit that includes an inverter connected to the power supply line and drives an AC motor; an MG power control means that controls electric power input to the MG unit; a system voltage control means that executes system voltage stabilization control to suppress variation in the system voltage by the MG power control means; a conversion power control means that executes conversion power control to control conversion power, which is electric power input to the power conversion means or electric power output from the power conversion means; a conversion voltage control means that executes conversion voltage control to control voltage output from the power conversion means; and a selection means that selects either the conversion power control or the conversion voltage control, and prohibits the system voltage control when the conversion voltage control is selected.
