Claim:
1. A pedal simulator installed at an electronic brake system which comprises a master cylinder coupled with a reserver and configured to generate an oil pressure according to a driver's pedal force, a pedal displacement sensor configured to detect displacement of a brake pedal, and an oil pressure generating device configured to output an electric signal corresponding to an operation of the brake pedal through the pedal displacement sensor, to operate a motor and to convert a rotating force of the motor into a rectilinear motion, the pedal simulator comprising: a pedal simulation unit connected with the master cylinder and configured to provide a reaction force according to the pedal force of the brake pedal; and a simulation valve connected with a rear end of the pedal simulation unit and configured to control a flow in a passage according to an opening and closing operation, wherein the simulation valve controls a flow rate of the oil by controlling a degree of opening and closing according to a back pressure transmitted to the pedal simulation unit through the oil pressure generating device.
