The invention discloses a pedal simulator braking system, a control method and a vehicle. The pedal simulator braking system comprises a brake pedal, a pedal displacement sensor, a pedal simulator module and an electronic control unit. The pedal displacement sensor is used for detecting a displacement signal of the brake pedal; the pedal simulator module comprises a simulator hydraulic cylinder and a servo motor; the electronic control unit is used for detecting a displacement signal of the brake pedal based on the pedal displacement sensor; in response to the pedal force feedback mode selection instruction, determining a target pedal force feedback mode; based on the displacement signal and the target pedal force feedback mode, target pressure corresponding to the simulator hydraulic cylinder is determined; and controlling the servo motor to work based on the target pressure. The corresponding target characteristic relation is selected according to different pedal force feedback modes, pedal braking feelings under different driving styles are obtained, and the pedal feelings are adjusted through the servo motor, so that the acceleration performance of the vehicle is more stable.
