Abstract
It is provided a control apparatus for a vehicle provided with an electric motor power source, an inverter, an electric motor, an inverter smoothing capacitor, and a step-variable automatic transmission, the control apparatus being configured to implement a torque reduction control, and to implement a torque reduction limitation control to limit reduction of an output torque of the electric motor to within a range in which a terminal voltage of the inverter smoothing capacitor will not exceed a predetermined withstanding voltage of the inverter and to limit the reduction of the output torque by limiting an amount of change of the output torque per unit time during the reduction of the output torque in the torque reduction control, to within a predetermined torque reduction rate limiting range, and wherein the torque reduction rate limiting range is determined upon initiation of a shifting action of the automatic transmission.
