Position and Force Sensor Assembly for Vehicle Brake Pedal
A vehicle pedal sensor assembly for use in a vehicle brake pedal including a base and a pedal arm pivotally mounted to the pedal base. A sensor housing includes a non-contacting pedal position sensor and a contacting pedal force sensor. The sensor housing is mounted to the base of the vehicle brake pedal. A magnet is mounted to the pedal arm. The pedal position sensor senses a change in the magnitude and/or direction of the magnetic field generated by the magnet in response to a change in the position of the pedal arm for determining the position of the pedal arm. A pedal force application member exerts a force against the pedal force sensor in response to the change in the position of the pedal arm for determining the position of the pedal arm. The force sensor may be a piezoelectric element, a load cell, or a strain gauge.
