Abstract: In order to maintain thermal comfort of the cabin environment of a pure electric vehicle and improve efficiency of energy use, this paper studies the control strategy of the heat pump air conditioning system for pure electric vehicles. AMESim is used to build a cabin simulation platform of the pure electric vehicle heat pump air conditioning system, and three control strategies are designed: compressor on/off control strategy, PID control strategy and fuzzy control strategy. Matlab/Simulink is used to simulate the three control strategies respectively, and then feedforward control is added and simulated on the basis of the fuzzy control strategy. The results show that the COP values under the compressor on/off control strategy, the PID control strategy and the fuzzy control strategy are about 1.5, 1.8 and 1.85 respectively; the temperature fluctuation is about 0.5 ℃ before the introduction of feedforward control, and there is no significant change after the introduction. The control performance of the fuzzy control strategy is better than that of the compressor on/off control and the PID control in terms of dynamic response and energy efficiency ratio of the system; after adding the feedforward control, the fuzzy control strategy effectively improves the dynamic response of the system when the external environment changes, and reduces the fluctuation of the cabin temperature.
