To make it possible to hinder over all frequency ranges an impact arising when parking lock is cancelled in a control device for an inverter for an electric vehicle.SOLUTION: A control device for an inverter for an electric vehicle comprises: an acceleration calculation unit 51 that calculates a detected acceleration from a detected motor phase θ obtained by detecting an electrical angle of a motor of an electric vehicle; a brake control unit 52 that calculates a brake compensation torque Tv by filtering, from the detected acceleration, a specific frequency component relating to resonance of the vehicle; a speed calculation unit 53 that obtains a motor acceleration by differentiating the detected motor phase θ; and a speed control unit 54 that outputs parking compensation torque Tp by subjecting the motor acceleration to proportional control using speed 0 as a target value. When parking lock is cancelled, torque obtained by adding the brake compensation torque Tv and the parking compensation torque Tp with an adder 56 is used as a compensation torque Tc. A difference between the torque command Tof the motor and the compensation torque Tc is obtained with a subtracter 57 to find a brake torque command T.SELECTED DRAWING: Figure 1
