Electronic throttle control pedal, position sensing device and assembly method

摘要

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.
