Abstract

The invention relates to a method of controlling an oil pump of a vehicle. The method includes: acquiring, by a controller, information on an engine operating state or a driving condition detected bya driving information detection part; determining, by the controller, whether a predetermined condition of an alternate mode is satisfied on the basis of the acquired information on the engine operating state or the driving condition; and, when the condition of the alternate mode is satisfied, sequentially performing, by the controller, a high-pressure operation control that controls an operationof an oil pump system so as to an oil pressure of an engine to converge on a predetermined target high-pressure value and a low-pressure operation control that controls the oil pressure of the engineto converge on a predetermined target low-pressure value.

Description

technical field [0001] The present invention relates to a method of controlling an oil pump of a vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not constitute prior art. [0003] An engine includes many parts, including moving parts, and during operation of the engine, the moving parts are in contact with each other. [0004] When moving parts come into contact with each other while moving in the engine, heat is generated due to friction, and a cooling fluid such as cooling water or oil is used to prevent damage to the parts due to the frictional heat. [0005] Oil also acts as a lubricant to reduce friction between engine components. As the oil pump operates, oil is delivered to every part of the engine. [0006] For example, in order to supply oil for lubrication to moving parts such as pistons or crankshafts of an engine, an oil supply device including an oil pump is p...
