Abstract:
1. An electronically controlled floor mounted pedal assembly with a position sensor comprising: a base member fixedly attached to a vehicle floor and having a lower portion and an upper portion; a control arm having a first free end and a second end pivotally mounted to the base member at a control arm pivot axis; a pedal arm pivotally mounted to the base member at a pedal arm pivot axis, wherein the pedal arm includes an inner surface, and the control arm free end is positioned adjacent the inner surface of the pedal arm such that the control arm transfers an angular rotation of the pedal arm about the pedal arm pivot axis into an angular rotation of the control arm about the control arm pivot axis, a control arm friction member mounted on the control arm free end, such that the control arm friction member contacts a pedal arm friction member positioned on the inner surface of the pedal arm, to generate a frictional hysteresis force that is translated back through the pedal arm as the pedal arm is depressed, the frictional hysteresis force providing a hysteresis feel during pedal operation; a return spring positioned between the base member and the control arm, wherein the return spring initially biases the control arm against the pedal arm; and a position sensor supported on the base member about the control arm pivot axis, wherein the position sensor is operatively connected to the control arm to sense angular rotation of the control arm about the control arm pivot axis as the pedal arm rotates about the pedal arm pivot axis, the control arm friction member being in sliding contact with the pedal arm friction member, the control arm friction member having a shape configured to achieve a linear relationship between the angular rotation of the pedal arm and the angular rotation of the control arm.
