Abstract
An adjustable control pedal for a motor vehicle includes an upper arm and a lower arm carrying a pedal. The lower arm is selectively moveable relative to the upper arm to adjust the position of the pedal relative to the upper arm. A drive screw is secured to the upper arm. A drive nut threadably engages the drive screw and is adapted to move axially along the drive screw upon rotation of the drive screw. A motor is operatively connected to the drive screw to selectively rotate the drive screw. The lower arm is operatively connected to the drive nut for fore-aft movement of the lower arm relative to the upper arm upon axial movement of the drive nut along the drive screw. A control system includes a sensor located at the drive screw and adapted to directly sense rotation of the drive screw and a controller in communication with the sensor to receive electrical signals from the sensor. The controller determines a position of the nut along the screw based on signals from the sensor and automatically stops the motor when the nut reaches a predetermined position along the screw such as a desired end of travel for the nut along the screw. The controller also automatically stops the motor…
