The invention relates to a control method of an electronic expansion valve, electronic equipment, an integrated heat management system and an engineering vehicle, and the control method of the electronic expansion valve comprises the steps that the current whole vehicle state of the engineering vehicle is obtained, and the whole vehicle state is used for representing the working state of a battery and/or an air conditioner; the opening degree of the electronic expansion valve is controlled to be opened to the current basic opening degree corresponding to the current whole vehicle state; the current superheat degree of the integrated heat management system and the preset superheat degree range corresponding to the current whole vehicle state are obtained; and if the current superheat degree is within the preset superheat degree range, the opening degree of the electronic expansion valve is kept to be the current basic opening degree. Thus, the opening degree of the electronic expansion valve can be automatically adjusted according to different whole vehicle states and superheat degrees, and the accuracy of temperature control is improved while cold distribution of the integrated heat management system is achieved.
本申请涉及一种电子膨胀阀的控制方法、电子设备、集成热管理系统及工程车辆,电子膨胀阀的控制方法包括:获取工程车辆的当前整车状态,整车状态用于表征电池和/或空调的工作状态;控制电子膨胀阀的开度打开至与当前整车状态对应的当前基础开度;获取集成热管理系统的当前过热度,以及与当前整车状态对应的预设过热度范围;若当前过热度处于预设过热度范围内,则保持电子膨胀阀的开度为当前基础开度。如此,可以根据不同整车状态和过热度自动调节电子膨胀阀的开度,在实现集成热管理系统的冷量分配的同时,提升了温控的准确性。
