Claim 0:
1. A motor control device for a vehicle including: an engine and a motor generator each serving as a power source; a transmission that transmits, to a wheel side, driving torque based on at least one of engine torque of a crankshaft of the engine and motor torque of a motor shaft of the motor generator at a selected change gear ratio; and
a damper including an input inertial member connected to the crankshaft, an intermediate inertial member connected to the input inertial member via at least a first elastic member, and an output inertial member connected to the intermediate inertial member via at least a second elastic member on an opposite side to the input inertial member, the damper being configured to reduce vibration of the crankshaft,
the motor control device comprising a hardware processor configured to:
calculate damper torque generated by the damper in accordance with a fluctuation of the engine torque on a basis of a difference between a crank angle as a rotation angle of the crankshaft and a motor angle as a rotation angle of the motor shaft;
calculate, on a basis of the calculated damper torque, reversed phase torque in reverse phase to the damper torque;
calculate a correction amount for a phase of the calculated reversed phase torque on a basis of a difference between a first value corresponding to a torsion angle between the input inertial member and the output inertial member and a second value corresponding to a torsion angle between the intermediate inertial member and the output inertial member; and
output a motor torque command to be provided to the motor generator on a basis of the reversed phase torque a phase of which has been corrected in accordance with the calculated correction amount.
