OIL PUMP CONTROL SYSTEM FOR VEHICLE AND OPERATION METHOD THEREOF

摘要

PURPOSE: A vehicle oil pump control system and an operation method thereof are provided to actively control the discharging flow rate of an oil pump by using an engine rotation number, the inner temperature variable of an engine control unit (ECU) or an oil temperature sensor, thereby improving the fuel efficiency of the engine. CONSTITUTION: A vehicle oil pump control system includes an oil pump (110), a hydraulic pressure control valve (120), an oil sensor (130), and a control unit (140). The oil pump forms the pressure for supplying oil to an engine. The hydraulic pressure control valve controls the pressure of oil supplied to the engine. The oil sensor senses the pressure and temperature of oil supplied to the engine. The controller controls the hydraulic pressure control valve so as to follow the target oil pressure value in which the monitored oil pressure is calculated.
