The invention discloses a control method and device for an electronic expansion valve, a vehicle and a storage medium, and the method comprises the steps that if the actual superheat degree of an evaporator of the vehicle does not meet a preset condition, a target pressure change value of a target pipeline of the corresponding vehicle and the target superheat degree of the evaporator are obtained; according to the target pressure change value, a target correction opening degree is determined; according to the target superheat degree, the actual superheat degree and the target correction opening degree, the opening degree of the corresponding electronic expansion valve is determined as the target opening degree; and the electronic expansion valve is controlled according to the target opening degree. According to the control method, the target opening degree is corrected through the target correction opening degree, so that the accuracy rate of the target opening degree is high, control over the opening degree of the electronic expansion valve is more accurate, and the working instability of the evaporator and the thermal management effect of the whole vehicle are improved.

    本申请公开了一种电子膨胀阀的控制方法、装置、车辆及存储介质,方法包括:若车辆的蒸发器的实际过热度不满足预设条件,获取对应车辆的目标管路的目标压力变化值以及蒸发器的目标过热度;根据目标压力变化值,确定目标修正开度;根据目标过热度、实际过热度以及目标修正开度,确定对应电子膨胀阀的开度作为目标开度;根据目标开度对电子膨胀阀进行控制。在本申请中,目标开度通过目标修正开度进行修正的,使得目标开度的准确率较高,从而使得电子膨胀阀的开度的控制更加准确,提高了蒸发器的工作不稳定以及整车的热管理效果。
