Abstract: A vehicle seat controller includes a feedback controller, a speed instruction value setting unit, and an entrapment determination unit. The feedback controller performs speed feedback control so that a rotation speed of the motor follows a speed instruction value based on a difference of the speed instruction value and an actual speed of the rotation speed of the motor. The speed instruction value setting unit sets the speed instruction value in accordance with a position of the vehicle seat. The entrapment determination unit determines entrapment of a foreign object entrapped by the vehicle seat when the vehicle seat is motor-driven. When the entrapment determination unit makes a foreign object entrapment determination, the speed instruction value setting unit changes the speed instruction value for an entrapment position of the vehicle seat to a low speed value that is smaller than a predetermined initial value.
