Electronic control pedal and position sensing device and assembly method
First Claim
1. An electronic control pedal comprising:
- a mounting bracket for mounting the pedal to a vehicle wall;
a shaft rotatably carried by the bracket;
a pedal beam operable with the shaft for rotation thereof;
hysteresis means operable with the pedal beam for providing a mechanical response to movement of a pedal pad; and
a position sensor responsive to movement of the pedal beam, the position sensor comprising;
a housing carried by the mounting bracket the housing having an opening therein for receiving the shaft therethrough;
a potentiometer carried within the housing, the potentiometer having a slider member sidable with a substrate in only a linear direction for providing an electrical output responsive to a linear displacement of the slider member along the substrate;
a drive arm rotatable by the shaft, the drive arm operable with the slider member for providing the linear displacement thereto resulting from a rotation thereof, the drive arm having a first arm member operable with a second arm member for telescoping adjustment therewith along a drive arm longitudinal axis of the drive arm for securing at a fixed position thereto, the drive arm longitudinal axis radially extending from the axis of rotation of the shaft, wherein a slot within the drive arm has a slot longitudinal axis positioned at a non-zero angle to the drive arm longitudinal axis; and
a coupler sidable within the slot, the coupler connected to the slider member for providing the linear displacement thereto.

Abstract
A position sensor for an electronic control pedal is carried by the pedal mounting bracket and includes a linear potentiometer having a slider operable along a substrate in only a linear direction for providing an output voltage representative of slider displacement. A drive arm is connected to the pedal shaft for rotation during pedal movement. A coupler connected to the slider is slidable within a slot in the drive arm for providing the linear displacement through a rotational movement of the shaft. The drive arm has an inner arm in a telescoping connection with an outer arm for setting the drive arm at a desired length after potentiometer calibration. The longitudinal axis of the slot is at an non-zero angle to the longitudinal axis of the drive arm for desensitizing the sensor calibration and adjustment process.
