Abstract:
A pedal simulator for a vehicle braking system comprising:a brake pedal;an electrical actuator operatively coupled to said brake pedal to selectively exert a force on said brake pedal;a position sensor for generating a position signal indicative of the position of said brake pedal;a force sensor for generating a force signal indicative of the force exerted upon said brake pedal by a driver; andan electronic control unit having programmed therein a desired relationship between said position signal and said force signal, said electronic control unit determining an actual relationship between said position signal and said force signal and comparing said actual relationship with said desired relationship and controlling said electrical actuator to selectively exert a force on said brake pedal to conform said actual relationship to said desired relationship, the electrical control unit developing a brake demand signal adapted to be supplied to a brake unit to cause the brake unit to supply all of a braking force.
