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.

Cooling control device for electrified vehicle

The drive device includes a first motor. The drive device includes a first rotational shaft that integrally rotates with a rotor of the first motor. The drive device includes a first counter shaft that is disposed parallel to the first rotational shaft and that is also connected to the first rotational shaft via a first counter gear. The drive device includes a first transmission shaft that is disposed coaxially with the first rotational shaft and that is also connected to the first counter shaft via a second counter gear. A series of oil channels is fashioned within the first rotational shaft and the first transmission shaft.

Drive device

The drive device comprises first and second motors comprising respective first and second rotary shafts. The drive device comprises first and second counter shafts connected to each of the first and second rotary shafts via first and second counter gears. The drive device comprises first and second transmission shafts connected to each of the first and second counter shafts via third and fourth counter gears. The drive device comprises first and second drive shafts connected to each of the first and second transmission shafts via first and second hypoid gears. The first and second rotary shafts are located between the first and second counter shafts with respect to the vehicle width direction. The first and second transmission shafts are located between the first and second counter shafts in the vehicle width direction.
