Title:
車両用シート装置
Document Type and Number:
Japanese Patent JP5831201
Kind Code:
B2
Abstract:
Provided is a vehicle seat apparatus (10) including drive mechanism (12) for moving configuring elements (6) of a vehicle seat (1) using a motor drive (11), in order to adjust a posture; a control mechanism (13) for controlling the operation of the drive mechanism; a rotation sensor (16) which outputs pulse signals (P) synchronized with a motor rotation; a position detection mechanism (13) for detecting a movement position of the configuring elements by counting pulse edges of the pulse signals according to the motor rotation direction; and a reverse rotation detection mechanism (13) 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 (E1, E2) after the stop becomes faster than the motor rotation speed before the motor drive is stopped.
