The embodiment of the invention relates to the technical field of automobiles, in particular to an electronic expansion valve control method and device and a vehicle, and the control method comprises the steps that in the vehicle running process, the air blower gear change state and the refrigeration mode change state of a heat pump air conditioner are obtained; when the air blower gear change state is a steep drop state and/or the refrigeration mode of the heat pump air conditioner is switched from a passenger compartment single refrigeration mode to a passenger compartment/battery dual refrigeration mode, correction parameters used for correcting the opening degree of a first electronic expansion valve are determined; a first current parameter used for determining the current opening degree of the first electronic expansion valve is obtained, the parameter is corrected according to the first current parameter, and an actual parameter is determined; and the first target opening degree of the first electronic expansion valve is determined according to the actual parameters, the first electronic expansion valve is adjusted to the first target opening degree, and the problem that the opening degree of the evaporator side electronic expansion valve is adjusted slowly is effectively solved.

    本申请实施例在于本申请实施例涉及汽车技术领域,具体而言,涉及一种电子膨胀阀的控制方法、装置及车辆,控制方法包括:在车辆行驶过程中,获取鼓风机档位变化状态以及热泵空调的制冷模式变化状态;在鼓风机档位变化状态为陡降状态,和/或在热泵空调的制冷模式由乘员舱单制冷模式切换至乘员舱/电池双制冷模式时,确定用于修正第一电子膨胀阀开度的修正参数;获取用于确定第一电子膨胀阀当前开度的第一当前参数,根据第一当前参数修正参数,确定实际参数;根据实际参数确定第一电子膨胀阀的第一目标开度,并将第一电子膨胀阀调节至第一目标开度,有效解决蒸发器侧电子膨胀阀的开度调节缓慢的问题。
