Abstract: A method of controlling an oil pump of a vehicle includes: acquiring, by a controller, information on an engine operating state or a driving condition detected by a 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 operation of 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 engine to converge on a predetermined target low-pressure value.

Abstract: An engine system may include: an engine including a plurality of combustion chambers generating driving torque by burning fuel; an intake line through which fresh air flows into the combustion chambers; an intake manifold for distributing fresh air supplied by the intake line to the combustion chambers; an exhaust line in which exhaust gas exhausted from the combustion chambers flows; a recirculation line branched from the exhaust line and joined to the intake line; a connection pipe disposed at a portion where the recirculation line and the intake line are joined; and a water line connecting the connection pipe and the intake manifold. Condensate water generated at the connection pipe flows in the water line.
