MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
First Claim
1. A motor control device for a vehicle having a motor and a lock mechanism for locking a rotation of vehicle wheels, the motor control device comprising:
- a detection device configured to detect for release of the lock mechanism;
a damping control device configured to suppress torsional vibration of a drive shaft; and
a current control device configured to control current flowing to the motor on the basis of a motor torque command value set by the damping control device,the current control being configured to channel an excitation current for generating a magnetic flux in the motor on the basis of the detection result of the detection device while the motor is not rotating.

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.
