Method and device for determining abnormal meshing state of fan, equipment and storage medium

Abstract

A method, device and equipment for determining an abnormal meshing state of a fan and a computer readable storage medium, and the method comprises the steps that after it is detected that a vehicle is started, according to a collected temperature value or an auxiliary switch signal value, it is determined that the fan meets a working starting condition, and the temperature value comprises a water temperature value or a temperature value after intercooling; according to the calculated first rotation energy of the fan, it is determined that the fan is disengaged, and the disengagement frequency of the fan is recorded; according to the calculated second rotation energy of the fan, it is determined that the working state of the fan is abnormal, and the number of abnormal times of the fan is recorded; and determining the abnormal working state of the fan as an abnormal meshing state based on the disengagement frequency of the fan and the abnormal frequency of the fan, thereby solving the technical problem that the fan cannot be disengaged due to the fact that whether the fan is not disengaged or is abnormally meshed when the vehicle is started cannot be distinguished in related technologies, achieving the purpose of accurately distinguishing the disengagement and the abnormal meshing of the fan, and improving the user experience. Therefore, the accuracy of identifying the abnormal meshing of the fan is improved.
