The invention discloses an electronic control brake pedal feeling simulation device and a control method thereof. The electronic control brake pedal feeling simulation device comprises a simulation device main cylinder installed at the rear of a brake pedal and a displacement sensor, the other end of the simulation device main cylinder is sequentially connected with a pressure regulating valve and a liquid storage tank, and the other end of the liquid storage tank is connected with the simulation device main cylinder. The simulation device main cylinder, the pressure regulating valve and the liquid storage tank form a closed loop. The pressure regulating valve is further in parallel connection with a check valve. The electronic control brake pedal feeling simulation device further comprises a control unit for receiving displacement mode signals output by the displacement sensor. The control unit outputs duty cycle, and a driving circuit outputs a current to drive the pressure regulating valve to generate electromagnetic force. The electronic control brake pedal feeling simulation device is compact in structure and favorable for being installed and arranged on a vehicle and can reduce production cost. The brake pedal and an electronic control technology are combined, the brake pedal feeling under various modes is achieved through electronic control, and the effect of a vacuum booster during brake can be simulated completely.
