Abstract
This vehicle seat device is equipped with a position detection unit which detects the movement position of a vehicle seat. The position detection unit is equipped with a forward direction counting unit and a reverse direction counting unit. The forward direction counting unit counts, in a forward direction, pulse edges during the driving of a motor and pulse edges during the time interval in which the motor current changes from a first polarity to a second polarity opposite to the first polarity due to driving of the motor being stopped. The reverse direction counting unit counts, in a reverse direction opposite to the forward direction, the pulse edges during the time interval in which the motor current changes from the second polarity to the first polarity after driving of the motor is stopped.
