The invention provides a decoupled electronic hydraulic brake system which comprises a pedal, a pedal push rod, a force simulator, a displacement sensor, a driving mechanism, a push rod and a main cylinder, the force simulator comprises a force simulator shell, a simulator push rod and an elastic piece, and the pedal is hinged to the pedal push rod; one end, deviating from the pedal, of the pedal push rod penetrates into the force simulator shell and is connected with the simulator push rod, and a limiting piece is arranged in the vertical direction of the pedal push rod to prevent the pedal push rod from being separated from the simulator push rod and sliding out of the force simulator shell; one end, deviating from the pedal push rod, of the simulator push rod penetrates into the elastic piece and penetrates out of the force simulator shell, the displacement sensor measures a pedal displacement signal according to movement of the simulator push rod, and the driving mechanism controls the push rod according to the pedal displacement signal so that the main cylinder can conduct pressure building braking. Therefore, force stagnation is achieved, and the pedal feeling simulator effect is improved.
