AI Technical Summary

Problems solved by technology

Therefore, when the variable starting point of oil pressure is set to low pressure, it is difficult to adjust the oil pressure during full load, and when the oil pressure is adjusted during full load, the variable starting point of oil pressure increases
Correspondingly, fuel efficiency drops

Abstract

An oil pump control system for a vehicle includes: an oil pump to form a pressure for supplying oil to an engine, an oil pressure adjustment valve to control a pressure of the oil supplied to the engine by controlling the pressure formed by the oil pump, an oil sensor to sense the pressure and temperature of the oil supplied to the engine, and a controller to monitor vehicle information inputted from outside and the oil pressure and temperature sensed by the oil sensor, determine a target oil pressure value based on engine RPM of the monitored vehicle information and the oil temperature, and control the oil pressure adjustment valve such that the monitored oil pressure follows the determined target oil pressure value.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0030958 filed on Mar. 27, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] Exemplary embodiments of the present invention relate to an oil pump control system for a vehicle, and particularly to an oil pump control system for a vehicle and an operating method thereof so as to control the oil pump to regulate oil pressure of an engine lubrication system. Background technique [0004] Conventional oil pump control systems for vehicles include one or two chambers and use the mechanical spring constant and pressure applied to the chambers to control the oil pressure of the engine lubrication system. [0005] According to this mechanical control method, conventional oil pump control systems for vehicles are controlled using only a fixed oil pressure. Therefore, when conventional oil p...
