Abstract The invention provides a start control method for an electronic pump of an automobile hydraulic system, which comprises the following steps of: S1, in the flameout process of an engine of the automobile hydraulic system, acquiring a pressure drop predicted value of system pressure according to a system pressure rise and fall model of the automobile hydraulic system; wherein the system pressure rising and falling model is established according to operation parameters of the automobile hydraulic system, and the operation parameters of the automobile hydraulic system comprise the oil temperature, the engine rotating speed and the torque of the automobile hydraulic system. S2, a pressure rise contrast value of system pressure of the automobile hydraulic system in the pressure building process is obtained according to a pressure building model of the electronic pump, and the pressure building model is built in advance according to operation parameters of the automobile hydraulic system in the pressure building pro
