FLOOR MOUNTED PEDAL WITH POSITION SENSOR
First Claim
1. An electronically controlled floor mounted pedal assembly with a position sensor comprising:
- a base member fixedly attached to the vehicle 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;
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.

Abstract
An electronically controlled floor mounted pedal assembly with a position sensor includes a base. A control arm is pivotally mounted to the base member at a control arm pivot axis, and a pedal arm is pivotally mounted to the base member at a pedal arm pivot axis. The control arm free end is positioned adjacent an inner surface of the pedal arm. A friction generating member mounted on the control arm free end contacts a pedal arm friction member positioned on the inner surface of the pedal arm to generate frictional hysteresis force. A spring positioned between the base member and the control arm free end initially biases the control arm against the pedal arm. A position sensor supported on the base member about the control arm pivot axis senses angular rotation of the control arm about the control arm pivot axis as the pedal arm rotates about the pedal arm pivot axis.

8. An electronically controlled floor mounted pedal assembly with a position sensor comprising:
-
a base member fixedly attached to the vehicle and having a lower portion and an upper portion, wherein the upper portion includes a front wall and a side wall extending from an edge of the front wall, and the front wall includes an opening; a control arm having a first free end and a second end pivotally mounted to the base member at a control arm pivot axis, wherein the control arm free end extends therethrough the opening in the base member front wall; a pedal arm pivotally mounted to the base member at a pedal arm pivot axis, wherein the pedal arm includes a pedal pad having an inner surface, and the control arm free end is positioned adjacent the inner surface of the pedal pad such that the control arm transfers an angular rotation of the pedal pad 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 wall positioned on the pedal arm inner surface; a return spring positioned between the base member and the control arm free end, wherein the return spring initially biases the control arm friction member against the pedal pad friction wall, such that rotation of the pedal arm by application of a load to the pedal arm compresses the return spring to generate a frictional hysteresis force that is translated back through 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 rotation of the control arm about the control arm pivot axis and translates the sensed rotational movement into a control signal indicating rotational movement of the pedal arm about the pedal arm pivot axis. - View Dependent Claims (9, 10, 11, 12, 13, 14)
