    • A method for controlling a vehicle air-conditioning system for cooling an interior of a vehicle is disclosed. The vehicle air conditioning system has a compressor coupled to an electronic control valve. The method includes reading a user manipulatable switch, determining a desired vehicle interior temperature based on the read user manipulatable switch, reading a plurality of sensors indicative of an interior and an exterior climate of the vehicle, determining a heat load on the vehicle air conditioning system, determining a desired evaporator discharge temperature, evaluating a humidity level inside the vehicle by determining a humidity ratio, filtering the updated electronic control valve duty cycle to obtain a new electronic control valve duty cycle based on the desired evaporator discharge temperature, and sending the new electronic control valve duty cycle to a compressor controller, wherein the controller is in communication with the electronic control valve and commands the valve to operate at the new duty cycle.
    • 公开了一种用于控制用于冷却车辆内部的车辆空调系统的方法。 车辆空调系统具有联接到电子控制阀的压缩机。 该方法包括读取用户可操纵开关,基于读取的用户可操纵开关来确定期望的车辆内部温度,读取指示车辆的内部和外部气候的多个传感器,确定车辆空调系统上的热负荷 ,确定所需的蒸发器排出温度,通过确定湿度比来评估车辆内的湿度水平,过滤更新的电子控制阀占空比,以基于期望的蒸发器排放温度获得新的电子控制阀占空比,并发送新的 电子控制阀工作循环到压缩机控制器,其中控制器与电子控制阀连通并且命令阀在新的占空比下操作。
