The invention belongs to the technical field of engine electric control systems, and particularly provides a hybrid power system based on P1 configuration and an electronic water pump control method, and the method comprises the following steps: collecting a whole vehicle signal to judge the whole vehicle state; calculating target rotating speeds of the electronic water pump in different whole vehicle states; the calculated target rotating speed is transmitted to a water pump controller of the electronic water pump; the water pump controller controls the electronic water pump to perform state switching according to the received target rotating speed; acquiring the actual rotating speed of the electronic water pump; comparing the actual rotating speed of the electronic water pump with a set target rotating speed; and delimiting the fault level of the electronic water pump according to the comparison result. Different rotating speed requirements are set for the rotating speed of the electronic water pump according to actual requirements, the changing requirements of the engine electronic water pump can be better met, and unnecessary energy loss is reduced.

    本发明属于发动机电控系统技术领域,具体提供一种基于P1构型的混合动力系统及电子水泵控制方法,所述方法包括如下步骤:采集整车信号判断整车状态;计算电子水泵在不同整车状态下的目标转速;将计算的目标转速发动到电子水泵的水泵控制器;水泵控制器控制电子水泵按照接收到的目标转速进行状态切换;获取电子水泵的实际转速;将电子水泵的实际转速与设定的目标转速进行比较;根据比较结果划定电子水泵的故障等级。电子水泵转速根据实际需要设定不同的转速需求,可更好的适应发动机电子水泵变化需求,减少不必要的能量损耗。
