The invention provides an automobile heat pump system control method and device, and the method comprises the steps: detecting the current compressor rotating speed of a compressor, and obtaining a pre-calibrated target COPCR critical rotating speed; judging whether the current rotating speed of the compressor is not greater than the target COPCR critical rotating speed or not; when it is judged that the current rotating speed of the compressor is not larger than the target COPCR critical rotating speed, closed-loop control is conducted on the compressor according to the determined target condensation temperature; determining a current target water temperature target; and finally, according to the target water temperature target, closed-loop control is conducted on the inlet water temperature of the plate heat exchanger through the PTC heater. Therefore, according to the method and the device, the COPCR characteristics of the compressor (heat pump) can be utilized to be compared with the performance coefficient of the PTC, so that a coupling control strategy of compressor rotating speed control and PTC power control is selected, the energy efficiency of an automobile heat pump system is improved, and the effect of improving the endurance mileage of the whole automobile is facilitated.

    本申请提供一种汽车热泵系统控制方法及装置,该方法包括:检测压缩机的当前压缩机转速,并获取预先标定的目标COPCR临界转速;判断当前压缩机转速是否不大于目标COPCR临界转速;当判断出当前压缩机转速不大于目标COPCR临界转速时,根据确定好的目标冷凝温度对压缩机进行闭环控制;再确定当前的目标水温目标;最后根据目标水温目标,通过PTC加热器对板式换热器的进口水温进行闭环控制。可见,该方法及装置能够利用压缩机(热泵)的COPCR特征,与PTC的性能系数进行对比,从而选择压缩机转速控制和PTC功率控制的耦合控制策略,进而提升汽车热泵系统的能效,从而有利于提升整车续航里程的效果。
