Abstract
A vehicle control systemincludes a water pumpwith an electromagnetic clutch, an oil relief device, an OCV, a water temperature sensor, and an ECU. The ECUcauses the electromagnetic clutch of the water pumpto be disengaged on the basis of the detection result detected by the water temperature sensor, and stops the coolant circulation. The ECUinstructs the OCVto adjust the lubricant pressure to low by an oil relief device. The ECUdetermines whether or not the adjustment of the lubricant pressure to low by the oil relief deviceis stopped on the basis of the detection result detected by the water temperature sensorwhen the engagement of the electromagnetic clutch of the water pumpcontinues for a given period.
