Electromotive-vehicular motor control apparatus

An electromotive-vehicular motor control apparatus, comprising:

• a motor that drives wheels;
• a power drive unit that controls the motor;
• a torque control unit that controls an output torque of the motor according to a request torque;
• an electric current control unit that controls an electric-power conversion operation of the power drive unit based on a torque command that is output from the torque control unit and on a detection signal from a current sensor that detects an electric current passed from the power drive unit to the motor;
• a number-of-revolutions detection unit that detects a number of revolutions of the motor and outputs a signal of a detected number of revolutions, which is a detected result;
• a target number-of-revolutions setting unit that sets a target number of revolutions for suppressing a torque fluctuation of the motor by using the detected number of the revolutions that has been output from the number-of-revolutions detection unit;
• a number-of-revolutions deviation calculation unit that calculates a first number-of-revolutions deviation that is a deviation between the target number of the revolutions that has been set by the target number-of-revolutions setting unit and the detected number of the revolutions;
• and
• a removal unit that outputs a signal of a second number-of-revolutions deviation obtained by removing only a deviation component generated due to a transient state of the number of the revolutions from the first number-of-revolutions deviation that has been calculated by the number-of-revolutions deviation calculation unit, wherein
• the torque control unit controls the output torque based on the second number-of-revolutions deviation that has been output from the removal unit.
