1. A vehicle control system comprising
a power unit including an internal combustion engine and a rotating electrical machine; an oil pump unit including an electric oil pump and a mechanical oil pump that is driven by the internal combustion engine, the oil pump unit cooling the rotating electrical machine; and a control apparatus that drives the mechanical oil pump, by starting the internal combustion engine, when the electric oil pump is in an idling state in which the electric oil pump fails to deliver a coolant at a predetermined flow rate and when a parameter related to an operating state of the electric oil pump exceeds a predetermined determination reference, the control apparatus limits an output of the rotating electrical machine in accordance with a degree by which the parameter related to the operating state of the electric oil pump exceeds the predetermined determination reference.
