Title: ELECTRONIC THROTTLE CONTROL PEDAL, POSITION SENSING DEVICE AND ASSEMBLY METHOD
Abstract:
A position sensor (46) for an electronic control pedal (10) is carried by the pedal mounting bracket (12) and includes a linear potentiometer (56) having a slider (58) operable along a substrate (60) in only a linear direction (62) for providing an output voltage representative of slider displacement. A drive arm (50) is connected to the pedal shaft (20) for rotation during pedal (16) movement. A coupler (84) connected to the slider (58) is slidable within a slot (78) in the drive arm (50) for providing the linear displacement through a rotational movement of the shaft (20). The drive arm (50) has an inner arm (74) in a telescoping connection with an outer arm (72) for setting the drive arm (50) at a desired length after potentiometer calibration. The longitudinal axis (80) of the slot (78) is at a non-zero angle (82) to the longitudinal axis (76) of the drive arm (50) for desensitizing the sensor (40) calibration and adjustment process.
