The invention relates to the technical field of intelligent braking, in particular to a hydraulic control device of an integrated intelligent braking system, which is characterized in that a main cylinder assembly is a serial two-cavity main cylinder, a first oil outlet and a second oil outlet of an oil pot are respectively connected with two oil inlets of the main cylinder assembly, and a third oil outlet of the oil pot is connected with an oil inlet of a servo pressure buildup unit; two oil outlets of the main cylinder assembly are respectively connected with an oil inlet of a main cylinder isolating valve; an oil outlet of the servo pressure buildup unit is respectively connected with the two servo pressure buildup unit isolating valves, and an oil outlet of the main cylinder isolating valve is respectively connected with the servo pressure buildup unit isolating valves and the wheel cylinder control loop; and the wheel cylinder control loop is connected with a third oil outlet of the oil can. The pedal feeling simulator has the advantages that the rear end of the pedal feeling simulator is not connected with an oil can, and failure of one system level is avoided; the hydraulic loop is divided into a pedal feeling simulation loop and a servo pressure buildup loop according to functions, and the pedal feeling simulation loop provides brake pedal simulation feeling according to signals of a pedal displacement sensor in the braking process.
