The invention relates to a control method of an electronic steering oil pump of an electric automobile. The method comprises the following steps: starting the electronic steering oil pump if the electric automobile is in a first state after the step of applying high pressure is completed; or otherwise, not starting the electronic steering oil pump, wherein the first state is that the current gearof the electric automobile is in a non-neutral gear state, parking braking is in a loosened state, and the automobile speed is not smaller than the set speed. After high pressure is applied to the vehicle, two situations occur: driving is needed and driving is not needed; if the electric vehicle is in the first state, it is indicated that a driver needs driving, then, the electronic steering oil pump is started at the moment, and the normal power-assisted steering function in the vehicle driving process is guaranteed; and when the electric vehicle is not in the first state, it is indicated that the driving is not needed, and the electronic steering oil pump is not started at the moment, so that the energy consumption of the whole electric vehicle after high pressure is applied to the electric vehicle in a static state can be reduced, the service life of the electronic steering oil pump is prolonged, the electronic steering oil pump is prevented from generating noise, and the riding comfort is improved.

    本申请涉及一种电动汽车电子转向油泵的控制方法,包括如下步骤:在完成上高压步骤后,若电动汽车处于第一状态时,启动电子转向油泵;否则,不启动电子转向油泵;其中,第一状态为:电动汽车当前档位为非空挡状态,驻车制动为松开状态,且车速不小于设定速度。本申请将车辆上高压之后的情形分成需要行车和不需要行车,若电动汽车处于第一状态,说明驾驶员需要行车,此时启动电子转向油泵,保证车辆行驶过程中的正常转向助力功能;而当不处于第一状态,说明不需要行车,此时不启动电子转向油泵,从而可以降低电动汽车在车辆静止状态下上高压后整车的能耗,延长了电子转向油泵的使用寿命,同时避免电子转向油泵产生噪音,提高了乘坐舒适性。
