| 发明名称 | Motor control device and motor control method | ||
| 摘要 | 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. | ||

| 主权项 | 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. | ||
