The invention discloses a vehicle, an electronic expansion valve control method and device and a medium, the method is applied to an air conditioning system of the vehicle, an electronic expansion valve is provided with a first side and a second side which are oppositely arranged, and the method comprises the steps that when the air conditioning system is closed, the current position of the electronic expansion valve is obtained; if the current position is different from the first target position, the electronic expansion valve is controlled to move to the first target position according to the preset speed, the preset speed is smaller than or equal to the speed threshold value, the preset speed is in positive correlation with the pressure difference change rate, and the pressure difference change rate is the pressure difference change rate in the movement process of the electronic expansion valve. A rate of change of a pressure difference between the first side and the second side; and when the electronic expansion valve reaches the first target position, the pressure difference value between the first side and the second side is smaller than or equal to a preset difference value. The vibration of the motor of the electronic expansion valve can become slow and discontinuous, so that the noise generated by the vibration of the motor is reduced, and the user experience is improved.
本申请公开了车辆、电子膨胀阀控制方法、装置和介质,方法应用于车辆的空调系统,电子膨胀阀具有相对设置的第一侧和第二侧,方法包括:在空调系统关闭时,获取电子膨胀阀的当前位置;若当前位置不同于第一目标位置,则控制电子膨胀阀按照预设速度运动到第一目标位置,其中,预设速度小于或等于速度阈值,预设速度与压差变化率之间呈正相关,压差变化率为电子膨胀阀运动过程中,第一侧和第二侧之间的压力差值的变化率;当电子膨胀阀到达第一目标位置时,第一侧和第二侧之间的压力差值小于或等于预设差值。本申请能够使得电子膨胀阀的电机的振动变得缓慢且不连续,进而降低电机振动产生的噪音,提高用户体验。
