The invention relates to the technical field of vehicles, in particular to a control circuit of an electronic expansion valve, an air conditioning system, a vehicle, a method and a medium. The signal conditioning circuit is used for boosting and amplifying the control signal; and the controller is used for generating a control signal according to the temperature and pressure when the refrigerant of the vehicle air conditioning system flows into and out of the electronic expansion valve, inputting the control signal into the signal conditioning circuit, and controlling the electronic expansion valve based on the control signal boosted and amplified by the signal conditioning circuit. Therefore, the problem that countercurrent overload is prone to occurring in a circuit of the electronic expansion valve in the related technology is solved.
本申请涉及车辆技术领域,特别涉及一种电子膨胀阀的控制电路、空调系统、车辆、方法及介质,其中,电路包括:电子膨胀阀;信号调节电路,用于对控制信号进行升压和放大;控制器,根据车辆空调系统的制冷剂分别流入和流出电子膨胀阀时的温度和压力生成控制信号,将控制信号输入信号调节电路,并基于信号调节电路升压和放大后的控制信号控制电子膨胀阀。由此,解决了相关技术中电子膨胀阀的电路易出现逆流过载等问题。
