Abstract: A first target module determines a first target output pressure of an engine oil pump based on a speed of the engine oil pump and an oil temperature. A second target module, based on a runtime period of an engine, sets a second target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A third target module, based on an engine load, sets a third target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A selection module selects one of the second and third target output pressures, sets a selected target output pressure based on the selected one of the second and third target output pressures, and controls displacement of the engine oil pump based on the selected target output pressure.
