The invention discloses an electric vehicle air conditioner control method which has the main design concept that after a variable frequency air conditioner compressor of an electric vehicle is allowed to be started, an initial compressor rotating speed value is given firstly, and the actual evaporation temperature is collected in real time so as to judge the temperature change trend; and according to the difference value between the actual evaporation temperature and the target evaporation temperature and the temperature change trend, the capacity of the compressor is subjected to compensation control within a set compensation period. The rotating speed of the compressor is more reasonable, frequent starting and stopping of the compressor are prevented, the compressor exerts the optimal performance, and therefore the precision of in-vehicle temperature control is improved, the comfort of passengers is improved, the energy efficiency ratio of the system is increased, meanwhile, the electric energy consumption of the whole vehicle by an air conditioner is effectively reduced, and then the cruising ability of the whole vehicle can be improved.
本发明公开了一种电动汽车空调控制方法,本发明的主要设计构思在于,在电动车的变频空调压缩机允许启动后,先给定初始的压缩机转速值,并实时采集实际蒸发温度以此判断温度变化趋势,根据当实际蒸发温度与目标蒸发温度的差值及温度变化趋势,对压缩机能力在既定的补偿周期内予以补偿控制。本发明通过使得压缩机的转速更为合理,防止压缩机频繁启停并使压缩机发挥最优性能,从而在提高车内温度控制的精度、提高乘员舒适性以及系统能效比的同时,有效降低空调对于整车电能的消耗,进而可以提高整车的续航能力。
