The invention discloses a method for controlling the rotating speed of a compressor with a heat pump system, which comprises the following steps of: adjusting the rotating speed of the compressor by adopting PID (Proportion Integration Differentiation), and adopting different PID parameters, control objects and control purposes according to different heat pump working modes; wherein the control object is a parameter which is changed due to the change of the rotating speed of the compressor, and the control purpose is a target value of the control object; and when the working modes of the heat pump are switched, the compressor firstly continuously runs for a preset time at a preset rotating speed and then is subjected to PID adjustment. According to the rotating speed control method, the rotating speed of the compressor is reasonably controlled on the premise of ensuring the comfort of a passenger compartment and certain battery efficiency, and the energy consumption of the whole vehicle is further reduced.

    本发明公开了一种带热泵系统的压缩机转速控制方法,该方法为,采用PID调节压缩机转速,并依据不同的热泵工作模式采用不同的PID参数、控制对象和控制目的;其中控制对象为因压缩机转速发生变化而产生变化的参数,控制目的为控制对象的目标值;热泵工作模式进行切换时,使压缩机首先以预设的转速持续运行预设的时间后再进行PID调节。该转速控制方法在保证乘员舱舒适性和一定电池效率的前提下合理的对压缩机转速进行控制,进一步降低了整车的能耗。
