The invention discloses an electronic expansion valve control method and device and an automobile, and relates to the technical field of expansion valves and automobiles. The electronic expansion valve control method comprises the steps that a target opening degree position instruction is obtained, and when it is determined that the position where a target opening degree is located is in the closing direction of the position where the current opening degree is located according to the target opening degree position instruction, the corresponding opening degree step number compensation amount between the position where the target opening degree is located and the position where the current opening degree is located is obtained; and controlling the electronic expansion valve to act from the position of the current opening degree to the position of the target opening degree according to the opening degree step number compensation amount. Thus, in the scheme, the return stroke error existing in the process that the electronic expansion valve moves in the closing direction can be compensated through the obtained opening step number compensation amount, the electronic expansion valve can accurately reach the position where the target opening degree is located when moving in the closing direction, and the control precision of the electronic expansion valve is improved.
本申请公开了一种电子膨胀阀控制方法、设备及汽车,涉及膨胀阀及汽车技术领域。其中,电子膨胀阀控制方法通过获取目标开度位置指令,并在根据所述目标开度位置指令确定目标开度所处位置在当前开度所处位置的关闭方向时,获取所述目标开度所处位置与当前开度所处位置之间对应的开度步数补偿量,从而根据所述开度步数补偿量,控制所述电子膨胀阀从所述当前开度所处位置动作至所述目标开度所处位置。如此,在本发明的方案中,能够通过获取的该开度步数补偿量,对电子膨胀阀在往关闭方向运动过程中存在的回程误差进行补偿,使电子膨胀阀在往关闭方向动作时能够精准达到目标开度所处位置,提高电子膨胀阀的控制精度。
