BRAKE PEDAL PAD EMBEDDED SENSING ELEMENTS FOR PEDAL FEEL MEASUREMENTS

     This idea is to use very thin sensors embedded directly into the brake pedal pad itself, thereby allowing a simple swap of the pedal pad with the sensor-imbued pad. This would be achieved by a thin membrane piezoelectric on a flat sheet [2]; a technology that is readily available whereby an input force produces an output voltage that can be read [3]. This could be placed within the first few millimeters of pad rubber [1] or overlaid on the back of the pad to cover all contact points between pad and pedal face.

     The problem with conventional methods, to measure pedal force, requires the addition of components to the pedal assembly. These components, such as the well-known Puck type transducer increase the height, weight, and input force dynamics of a driver's foot; which skews results and are capable of introducing variation, due to angle of seat / height of driver / type of shoes / connection method (of sensor to pedal) / etc.

     The biggest advantage to this system is consistent and accurate measurement. This is due to the height profile of the pedal pad not changing, thus you are unable to induce a rotational force on the pad which skews the measurement results. But in addition to this, ease of installation; pedal pads come off and are reinstalled within seconds with no additional hardware required.
