The invention provides a hydraulic control system for an electromechanical coupler and a control method for the hydraulic control system. The system comprises a first oil pump, a second oil pump, a controller, a cooling lubricating oil path, a clutch control oil path and a pilot control oil path, wherein the cooling lubricating oil path comprises a plurality of pipelines and a cooler; an oil inletof the cooler is connected to the first oil pump through a first pipeline; an oil outlet of the cooler is separately connected to a power generator, an electric motor and a clutch through pipelines;the first oil pump and the second oil pump are separately connected to an oil tank; the pilot control oil path comprises a decoupling reversing valve and a first pilot solenoid valve which are connected through a pipeline, and the decoupling reversing valve is connected to the cooler through a second pipeline; the clutch control path comprises a third pipeline and a fourth pipeline; one path of anoil outlet of the second oil pump is connected to the decoupling reversing valve through a third pipeline, and the other path of the oil outlet of the second oil pump is connected to the clutch through a fourth pipeline; and the controller is separately connected to the first oil pump, the second oil pump and the first pilot solenoid valve. The system is used for realizing the method. During vehicle power mode switching, the hydraulic control system of the electromechanical coupler keeps good control performance, efficiency and part cost.
