A cooling control device for an electrified vehicle comprising: a first electric oil pump for supplying oil to a first motor for driving a front wheel; and a second electric oil pump for supplying oil to a second motor for driving a rear wheel, wherein the device is capable of switching between a four-wheel drive travel mode and a two-wheel drive travel mode in which a second motor is used as a driving force source; wherein when a two-wheel drive travel mode is selected, the device starts operating the first electric oil pump when only the second electric oil pump is driven and it is predicted to run in a four-wheel drive travel mode.
A cooling control device for an electrified vehicle including a first motor that drives a first drive wheel as one of front and rear wheels, a first electric oil pump that supplies oil to the first motor, a second motor that drives a second drive wheel as another of the front and rear wheels, a second electric oil pump that supplies the oil to the second motor, a first drive unit that transfers torque from the first motor to the first drive wheel, a second drive unit that transfers torque from the second motor to the second drive wheel, and a mechanical oil pump driven by the first drive unit to supply the oil to the first drive unit, the electrified vehicle being switchable between a four-wheel drive travel mode in which the first motor and the second motor are used as drive force sources and a two-wheel drive travel mode in which the second motor is used as a drive force source, the cooling control device comprising a controller that controls the first electric oil pump and the second electric oil pump, wherein the controller includes
