The invention relates to a tractor brake pedal force compensation simulator and a control method. The tractor brake pedal force compensation simulator comprises a torque sensor, a compensation motor, a torque transmission gear set, an oil storage tank, a brake master cylinder, a pressure simulation cavity oil return one-way valve, a second cavity oil return one-way valve, a first cavity brake control valve, a second cavity brake control valve, a front axle brake wheel cylinder diverter valve, a rear axle brake wheel cylinder diverter valve and a brake pressure source. The device comprises a first-stage simulation cylinder, a second-stage simulation cylinder, a second-stage simulation cylinder hydraulic control one-way valve, a second-stage simulation cylinder control valve, a simulation cylinder oil return collecting valve, a simulation cylinder oil return control valve, a contact displacement sensor, a brake pedal, a brake pedal force sensor, a brake pedal travel sensor, a simulator control valve and an ECU (electronic control unit). Selection of one section or two sections of pedal force is achieved, feedback force compensation of the pedal can be achieved under the complex road surface operation condition, and accurate tractor pedal force feedback is obtained.
