The invention discloses a control method of an electric steering pump, an electric steering system and an automobile. The electric steering pump comprises a motor and a pump body; the control method of the electric steering pump comprises the steps that the vehicle speed-oil pump rotating speed relation, the current vehicle speed and the current vehicle state are obtained; if the current vehicle state is driving, the oil pump rotating speed matched with the current vehicle speed is determined according to the current vehicle speed and the vehicle speed-oil pump rotating speed relation; if the current vehicle state is parking, the rotating speed of a parking oil pump serves as the rotating speed of the oil pump matched with the current vehicle speed; and controlling a motor to rotate according to the oil pump rotating speed matched with the current vehicle speed so as to drive a pump body. Compared with the prior art, the rotating speed of the oil pump is determined according to the vehicle state and the real-time speed of the vehicle, the power loss of the electric steering pump is avoided, and the energy consumption of the vehicle is reduced.

    本发明公开了一种电动转向泵的控制方法、电动转向系统及汽车。电动转向泵包括电机和泵体;所述电动转向泵的控制方法包括:获取车速‑油泵转速关系、当前车速和当前车辆状态;若所述当前车辆状态为行车,则根据所述当前车速和所述车速‑油泵转速关系确定与当前车速匹配的油泵转速;若所述当前车辆状态为驻车,则将驻车油泵转速作为所述与当前车速匹配的油泵转速;根据所述与当前车速匹配的油泵转速控制电机旋转,从而驱动泵体。与现有技术相比,本发明实施例根据车辆状态和车辆的实时速度确定油泵转速,有利于避免电动转向泵的功率损失,降低汽车能耗。
