Abstract
A motor control device of a vehicle including an engine and a motor generator, a transmission transmitting an engine torque and/or a motor torque to a wheel, and a damper reducing vibration of a crankshaft of the engine includes: a damper torque calculation unit calculating a damper torque generated by the damper according to fluctuation in engine torque based on a difference between a crank angle and a motor angle; a reverse-phase torque calculation unit calculating a reverse-phase torque with a reverse phase to the damper torque; a correction amount calculation unit calculating a first value calculated at least based on the crank angle and the motor angle; and a motor torque command output unit outputting a motor torque command given to the motor generator based on the reverse-phase torque corrected by the correction amount.
