Abstract
A vehicular pedal assembly includes a pedal including a first support and a second support, a pedal shaft supported by the pedal housing for rotation about a pedal axis, a pedal arm drivably engaged with the pedal shaft to rotate the pedal shaft about the pedal axis, and a position sensor assembly coupled to the pedal shaft and operable to determine a rotational position of the pedal shaft and generate a signal based on the rotational position. The pedal shaft includes a first shaft portion coupled to the first support, a second shaft portion coupled to the second support, and a joint coupling the first shaft portion and the second shaft portion. The joint is positioned between the first support and the second support.
