Abstract
Pedal mounted sensors are useful in vehicles for delivering an electrical signal correlative to the position of the pedal position. A pulse-width-modulated signals is preferable because it is less susceptible to signal degradation from engine noise or other factors. A pedal mount sensor capable of measuring a plurality of different angle ranges is disclosed. A stationary portion of the potentiometer includes both a mother board and a daughter board to improve manufacturability of the potentiometer. An application specific integrated circuit is substituted for direct pulse-width-modulation circuitry that permits a second, redundant circuit to be included within the potentiometer housing.
