1. A vehicle pedal resistance and dampener assembly comprising:
a dampener module defining an interior fluid-filled cavity and adapted for generating a dampening force on a vehicle pedal;
a resistance module adapted for generating a resistance force on the vehicle pedal, the dampener module and the resistance module being moveable relative to each other;
a sleeve in the dampener module defining the interior fluid-filled cavity;
a shaft in the cavity of the dampener module;
a fluid-filled interior sleeve in the resistance module, the shaft of the dampener module extending into the sleeve of the resistance module;
a first ring seal surrounding the sleeve of the resistance module;
a second ring seal surrounding and moveable relative to the sleeve of the resistance module;
a first resistance spring in the resistance module extending between an end of the resistance module and the shaft of the dampener module;
a second resistance spring in the resistance module surrounding and spaced from the sleeve of the resistance module;
a third resistance spring in the dampener module extending from an end of the dampener module and surrounding the shaft in the dampener module;
a pedal position sensor assembly for sensing and measuring the position of the vehicle pedal; and
a pedal force sensor assembly for sensing and measuring the force on the vehicle pedal.
