Patent ID: 8395277

Claim:
A control device for a vehicle including a power storage device, a converter for variably stepping up a voltage provided from said power storage device, an inverter for converting power output from said converter, and a motor that operates using the power output from said inverter, the control device comprising: a first control unit for controlling an output voltage of said converter based on a voltage command value; a second control unit for controlling said inverter to supply said motor with a rectangular wave voltage that is based on a torque command value, which designates an output torque of said motor, and said voltage command value; and a third control unit for controlling said voltage command value and said torque command value such that a difference between said torque command value and an actual output torque of said motor is smaller than a predetermined value when increasing said voltage command value, said third control unit increasing said voltage command value and said torque command value, stepwisely and alternately.
