The invention provides a control method and system of a parallel type hybrid power system and the parallel type hybrid power system, and belongs to the technical field of engineering equipment.The method comprises the steps that whether the working mode of the parallel type hybrid power system is a hybrid power mode or not is determined; when the working mode is a hybrid power mode and the parallel type hybrid power system has no power generation requirement, rotating speed control is conducted on a motor and an engine based on a first target rotating speed and a second target rotating speed, the first target rotating speed is the target rotating speed of the parallel type hybrid power system, and the second target rotating speed is equal to the difference value between the first target rotating speed and the rotating speed correction value; the rotational speed correction value is determined based on a difference between an actual rotational speed of the electric machine and an actual rotational speed of the engine. The method is used for overcoming the defects that in the prior art, due to the fact that different power components of the parallel type hybrid power system are controlled through the rotating speed and the torque respectively, the rotating speed is prone to being out of control under the transient working condition, and the energy consumption loss is large.

    本发明提供一种并联式混动系统的控制方法、系统及并联式混动系统,属于工程设备技术领域,其中方法包括:确定并联式混动系统的工作模式是否为混合动力模式;在工作模式为混合动力模式,且并联式混动系统无发电需求时,基于第一目标转速和第二目标转速分别对电机和发动机进行转速控制,第一目标转速为并联式混动系统的目标转速,第二目标转速等于第一目标转速与转速修正值的差值,转速修正值基于电机的实际转速和发动机的实际转速的差值确定。本发明用以解决现有技术中因采用转速和扭矩分别控制并联式混动系统的不同动力部件,所造成的在瞬态工况下容易转速失控,且能耗损失较大的缺陷。
