Abstract

The invention relates to a control method and device of an electronic oil pump, electronic equipment and a storage medium. The control method of the electronic oil pump comprises the following steps that current oil pressure load information of a hydraulic system is obtained during triggering of a preset event, and the electronic oil pump is controlled to be opened or closed if the current oil pressure load information meets the preset conditions. By means of the control method, the essence is to control the opening or closing time of the electronic oil pump based on the current oil pressure load of the hydraulic system in real time, and the purpose that the adverse phenomenon that the service life of an electronic oil pump is affected due to the excessive load of the electronic oil pump is also avoided while the working pressure of a gearbox is ensured is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle control, and in particular to a control method, device, electronic equipment and storage medium of an electronic oil pump. Background technique [0002] At present, for the automatic transmission that supports the start-stop function, its core component is the electronic oil pump. When the start-stop function is activated, the engine will turn off and stop, because the mechanical pump is driven by the engine to establish the working oil pressure for the transmission hydraulic system, so when the engine is turned off, the mechanical pump cannot establish the working pressure for the transmission hydraulic system. Activate the electronic oil pump to provide working oil pressure for the transmission hydraulic system; when the engine starts and the mechanical pump is sufficient to provide working pressure, the electronic oil pump needs to be turned off. [0003] A good electronic oil pump co...
