The embodiment of the invention discloses a compressor rotating speed control method and system. The method comprises the steps that the final rotating speed of a compressor is cooperatively determined according to compressor rotating speeds corresponding to a plurality of parameters; the parameters comprise the evaporator temperature, the abnormal resonance point, the cold and warm gears, the remaining electric quantity of the whole vehicle and the power of the whole vehicle. According to the embodiment of the invention, the surface temperature of the evaporator, the NVH resonance point, the remaining electric quantity of the whole vehicle, the power distribution of the whole vehicle and the setting of the cooling and heating gears are fully combined, the more reasonable rotating speed of the electric compressor is obtained, the NVH noise reduction performance is effectively improved, and the power consumption of the whole vehicle is reduced.

    本公开实施例公开一种压缩机转速控制方法及系统,所述方法包括:根据若干参数分别对应的压缩机转速协同确定压缩机最终转速;所述若干参数包括:蒸发器温度、异常共振点、冷暖档位、整车剩余电量与整车功率。本公开的示例性实施例,充分结合蒸发器表面温度、NVH共振点、整车剩余电量、整车功率分配、冷暖档位设定,并集得出更合理电动压缩机转速,有效提升NVH降噪性能以及降低整车功耗。
