Seat apparatus for vehicle

A vehicle seat device includes a lock mechanism, a drive source, which has an output portion, a cancellation detection portion, which detects the cancellation of restriction by the lock mechanism, and a restriction detection portion, which detects restriction by the lock mechanism. When cancelling restriction on the basis of operation of the operation switch, current is supplied to the drive source such that the output portion moves in the forward direction until the cancellation detection portion has detected cancellation, and when the cancellation has been detected, the supply of current to the drive source is stopped. When performing the restriction on the basis of operation of the operation switch, current is supplied to the drive source such that the output portion moves in the reverse direction until the restriction detection portion has detected restriction, and when restriction has been detected, the supply of current to the drive source is stopped.

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.

Vehicle seat apparatus

A seat apparatus for a vehicle, includes a main support control means for moving a side support portion inwardly and outwardly by means of a driving portion depending on a road shape, a support control means for operating the side support portion on the basis of an electronic map data before the vehicle reaches a curve starting point, a distance calculating means for calculating distance between an intersection and the curve starting point on the basis of the electronic map data, the intersection and the curve starting point, a determining means for determining whether or not control of the support control means is executed on the basis of the calculated distance and electronic map data accuracy, a means for executing the control of the support control means on the basis of determination of the determining means, and a means for refraining the control of the support control means.

A control device for a vehicle seat is provided. This control device for the vehicle seat is provided with a control unit. In order to improve the performance of getting into and out of a vehicle, the control unit executes an away movement for moving the vehicle seat to the rear of the vehicle when a preset away condition is satisfied, and when a preset return condition is satisfied in this state, executes a return movement for moving the vehicle seat to the front of the vehicle. The return condition includes, as a first return condition, a vehicle door being closed with a portable key in the vehicle.

Control device for vehicle seat

A power seat device includes a motor, an adjustment operation member, a Hall sensor, an ECU, a memory, and a single request operation member. The adjustment operation member adjusts a seat position. The Hall sensor detects a seat position. The ECU drives and controls the motor in accordance with an operation of the adjustment operation member to adjust the seat position. The memory stores two seat positions adjusted by the adjustment operation member. The request operation member sequentially retrieves the two seat positions stored in the memory when pushed. The ECU drives and controls the motor to reinstate the seat position retrieved by the operation of the request operation member. The ECU automatically stores a seat position before the reinstatement of the retrieved seat position is started in the memory.
