The invention relates to the technical field of double-clutch control, in particular to a double-clutch pressure control method and system. The double-clutch pressure control method comprises the steps that after a vehicle runs, expected torque and actual pressure of clutches are obtained in real time; expected pressure is obtained through calculation according to the expected torque; estimated pressure is obtained through calculation according to the expected pressure; limited pressure is obtained according to the actual pressure and the estimated pressure; and the expected pressure and the limited pressure are added to obtain requested pressure, and currents are obtained according to the requested pressure and output to double-clutch electromagnetic valves, so that the double-clutch electromagnetic valves are controlled to work. The response time of a double-clutch hydraulic system is shortened by means of the double-clutch pressure control method and system.
