Abstract: A vehicle seat includes a seat movable along a path a motor for driving the seat on the path, a sensor generating a signal indicating movement of the seat on the path, and a controller operating the motor to move said seat along the path. The sensor is preferably a Hall-effect device or a potentiometer. The controller is in communication with the sensor to receive the signal and form a feed-back control loop. The controller accelerates the seat at a controlled rate of acceleration to a controlled constant speed and decelerates the seat from the constant speed at a controlled rate of deceleration. The controller controls the rate of acceleration of the seat at a stored predetermined rate of acceleration by adjusting operation of the motor to maintain the predetermined rate of acceleration.
