Abstract
Provided is a vehicle seat apparatus including drive mechanism for moving configuring elements of a vehicle seat using a motor drive, in order to adjust a posture; control mechanism for controlling the operation of the drive mechanism; a rotation sensor which outputs pulse signals synchronized with a motor rotation; position detection mechanism for detecting a movement position of the configuring elements by counting pulse edges of the pulse signals according to the motor rotation direction; and reverse rotation detection mechanism for estimating that a reverse rotation has occurred in the motor rotation, in a situation where the pulse edges are continuously detected after the motor drive is stopped, if the rotation direction is unchanged, in a case where a motor rotation speed indicated by the pulse edges after the stop becomes faster than the motor rotation speed before the motor drive is stopped.
