Beschreibung
Zusammenfassung:	The invention aims to provide a hydraulic control system of a hybrid power transmission, a control method and a vehicle, wherein the hydraulic control system is low in cost and simple in structure. The hydraulic control system comprises an oil tank and an oil pump communicated with the oil tank. The single clutch is arranged between a generator and a driving motor of the hybrid electric vehicle and is provided with a clutch lubricating oil way and a clutch pressure oil way; one oil inlet of the switch electromagnetic valve is communicated to the oil tank, and the other oil inlet of the switch electromagnetic valve is communicated to the oil pump; one oil inlet of the switching mechanical valve is communicated to the oil tank, the other oil inlet of the switching mechanical valve is communicated to the oil pump, and an oil outlet of the switching mechanical valve is communicated to the clutch pressure oil way; an oil inlet of the main pressure regulating mechanical valve is communicated to the oil pump, an oil
