Abstract
A controller for a vehicle seat for optimally controlling the posture of a vehicle seat. An amount of a running condition of the vehicle is detected, and a controlled variable for a posture of the seat for appropriately holding an inertial force acting on an occupant seated in the seat is determined in correspondence with the amount of the running condition of the vehicle detected. In addition, an amount of displacement of a posture of the vehicle is detected, and the posture of the seat is controlled on the basis of the controlled variable for the posture of the seat and the amount of displacement of the posture of the vehicle. Since the posture of the seat is controlled in correspondence with not only the running condition of the vehicle but postural displacement of the vehicle, the holding characteristic of the driver's seat improves and permits driving with a comfortable and more stable posture.
