Abstract
A motor control device of a vehicle includes a motor and a lock mechanism for locking the rotation of vehicle wheels. The motor control device includes a detection device for detecting release of the lock mechanism, a damping control device for suppressing torsional vibration of a drive shaft, and a current control device for controlling current flowing to the motor on the basis of a motor torque command value set by the damping control device. The current control device channels an excitation current for generating a magnetic flux in the motor on the basis of the detection result of the detection device.
