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 transfers, to wheels, a driving torque based on at least one of an engine torque of a crankshaft of the engine and a motor torque of a motor shaft of the motor generator at a selected change gear ratio; and a damper that is provided between the engine and the transmission and reduces vibration of the crankshaft by using an elastic member, the motor control device comprising a hardware processor configured to:
calculate a first torsion torque generated by the motor shaft according to fluctuation of the engine torque based on a difference between a motor angle as a rotation angle of the motor shaft and a shaft angle as a rotation angle of a transmission shaft of the transmission on a downstream side of the damper;
calculate a first vibration damping torque to be output by the motor generator to damp vibration of the motor shaft based on the first torsion torque and a drive state value indicating a drive state of the engine; and
output a motor torque command value to be provided to the motor generator based on the first vibration damping torque.
