Abstract: An adjustable control pedal for a motor vehicle includes an upper arm, a lower arm supported by the upper arm and operatively connected to the upper arm for selected movement relative to the upper arm, and a drive assembly operatively connected to the lower arm to selectively move the lower arm relative to the upper arm. The drive assembly includes a drive screw connected to one of the upper and lower pedal arms, a drive nut connected to the other of the upper and lower pedal arms and cooperating with the drive screw such that the drive nut travels along the drive screw upon rotation of the drive screw, and an electric motor operatively connected to the drive screw to selectively rotate the drive screw. A hall-effect sensor is located adjacent the drive screw and cooperates with a ring magnet rotatable with the drive screw to detect motion information, including distance and velocity information, upon rotation of the drive screw.
