Abstract
The motor vehicle comprises a first motor configured to drive front wheels; a second motor configured to drive rear wheels; and a control device configured to control the first motor and the second motor, such that the motor vehicle is driven with a required torque for driving. The control device controls the first motor and the second motor to set a larger value to a rear wheel distribution ratio that is a ratio of a torque of the rear wheels to the required torque, when the motor vehicle runs on a low μ road having a road surface friction coefficient equal to or less than a predetermined value and is currently turned, compared with a value when the motor vehicle does not run on the low μ road or when the motor vehicle is not currently turned.
