Abstract
A vehicle cooling system comprises an oil circulation circuit in which a cooling oil is circulated by an electric oil pump to cool a predetermined cooling target with the cooling oil; an oil temperature sensor detecting an oil temperature that is a temperature of the cooling oil; and a control device including a cooling control portion outputting a rotation command for operating the electric oil pump so as to cool the cooling target. The control device includes a pump abnormality determination portion outputting the rotation command to the electric oil pump to determine a presence/absence of abnormality based on a rotation state of the electric oil pump when an operation stop time of the vehicle is longer than a predefined determination permission time and an oil temperature detection value detected by the oil temperature sensor is higher than a predefined determination permission temperature.
