The invention relates to an automobile electronic water pump stall eliminating method and device and a storage medium, and belongs to the technical field of automotive electronic water pumps. The method comprises the steps of obtaining current electric current flowing through a motor in the automobile electronic water pump; controlling the motor to rotate in the reverse direction when the currentelectric current is larger than an electric current threshold; and controlling the motor to rotate in the positive direction at first speed when the duration of reverse rotation of the motor reaches afirst predetermined duration so that the motor can enter the normal running state. The problem that the efficiency of manually eliminating the stall phenomenon is low can be solved; and after the reverse rotation of the motor, impurities which block an impeller in a pipeline can be rotated back, so that the stall phenomenon can be automatically achieved, and the stall elimination efficiency can be improved.
Description
technical field [0001] The application relates to a method, a device and a storage medium for eliminating a stall of an automotive electronic water pump, and belongs to the technical field of the automotive electronic water pump. Background technique [0002] With the increasingly stringent emission requirements of fuel vehicles and the development of new energy vehicles, more and more electronic water pumps will be used in the water pumps used to provide fluid power for the cooling circuits of key parts such as engines and batteries. Due to the existence of certain impurities in the cooling circuit where the electronic water pump is located, a certain proportion of the impeller will be blocked at this time. [0003] In the prior art, if the impeller is blocked, the control system controls the click in the electronic water pump to stop the operation and outputs an alarm through the host computer. After receiving the alarm, the user manually eliminates the phenomenon of impe...
