A vehicle pedal with a pedal base defining a sensor housing and a pedal arm overlying and spaced from and pivotally coupled to the pedal base. A sensor in the sensor housing includes a sensor element that moves in the direction of the pedal base in response to the movement of the pedal arm to generate an electrical signal used to determine to position of the pedal arm. In one embodiment, the sensor includes a strain gage and the sensor element is an actuator that flexes the strain gage. In another embodiment, the sensor includes a Hall Effect sensor and the sensor element is magnet whose movement results in a magnetic field change sensed by the Hall Effect sensor. In a further embodiment, the sensor element is a cap with wipers that slide against a resistive element. |
