The invention is suitable for the technical field of automobiles, and provides a control method and device of an electronic expansion valve, a storage medium and a vehicle. A first opening interval used by the electronic expansion valve comprises at least two sections of first opening subintervals with different flow change rates, the flow change rates represent the change rate between the adjustment step number and the refrigerant flow, and the control method comprises the steps that the first target opening of the electronic expansion valve is obtained; the first target opening degree is adjusted to obtain a second target opening degree, so that the change rate between the adjustment step number of the electronic expansion valve from the current opening degree to the second target opening degree and the refrigerant flow is a preset change rate, and the preset change rate is smaller than or equal to the lowest flow change rate corresponding to at least two sections of first opening degree subintervals; and opening control is conducted on the electronic expansion valve according to the second target opening. According to the embodiment of the invention, the stability of refrigerant flow change in the opening degree adjusting process can be kept.

    本申请适用于汽车技术领域,提供了一种电子膨胀阀的控制方法、装置、存储介质和车辆。其中,电子膨胀阀使用的第一开度区间包括流量变化率互不相同的至少两段第一开度子区间,流量变化率表征调整步数和制冷剂流量之间的变化率,控制方法包括:获取电子膨胀阀的第一目标开度;对第一目标开度进行调整,得到第二目标开度,使得电子膨胀阀由当前开度至第二目标开度之间调整步数和制冷剂流量之间的变化率为预设变化率,预设变化率小于或等于至少两段第一开度子区间对应的最低流量变化率;根据第二目标开度,对电子膨胀阀进行开度控制。本申请的实施例可以保持开度调整过程中制冷剂流量变化的稳定性。
