Abstract

A pedal simulator for a vehicle braking system. The pedal simulator is coupled to a brake pedal, and includes an electrical actuator operatively coupled to the brake pedal to selectively exert a force on the brake pedal. A position sensor is provided for generating a position signal indicative of the position of the brake pedal. A force sensor is provided for generating a force signal indicative of the force exerted upon the brake pedal by a driver. An electronic control unit is provided which has programmed therein a desired relationship between the position signal and the force signal. The electronic control unit determines an actual relationship between the position signal and the force signal and compares the actual relationship thus determined with the desired relationship. The electronic control unit controls the electrical actuator to selectively exert a force on the brake pedal to conform the actual relationship to the desired relationship.
