  • Motor control device
    Patent number: 11926309
    Abstract: A motor control device which is an example of the present disclosure includes a hardware processor configured to: calculate damper torque on a basis of a difference between a crank angle and a motor angle; calculate, on a basis of the damper torque, reversed phase torque in reverse phase to the damper torque; calculate a correction amount for a phase of the reversed phase torque on a basis of a difference between a first value corresponding to a torsion angle between an input inertial member and an output inertial member and a second value corresponding to a torsion angle between an intermediate inertial member and the output inertial member; and output a motor torque command to be provided to a motor generator on a basis of the reversed phase torque a phase of which has been corrected in accordance with the correction amount.
