US 2013/0259709 A1 · OIL PUMP CONTROL SYSTEM FOR VEHICLE AND OPERATION METHOD THEREOF

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.

Dependent claims

An oil pump control system for a vehicle, comprising:

an oil pump to form a pressure for supplying oil to an engine;
an oil pressure adjustment valve fluid-connected to the oil pump 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 an temperature of the oil supplied to the engine;
and
a controller to monitor a vehicle information inputted from outside and the pressure and the temperature sensed by the oil sensor, wherein the controller determines a target oil pressure value based on an engine RPM of a monitored vehicle information and the oil temperature, and control the oil pressure adjustment valve such that a monitored oil pressure follows a determined target oil pressure value.
