Abstract
A motor vehicle sets a front wheel average rotation speed that is an average rotation speed of left and right front wheels, based on a rotation speed of a first motor, and sets a rear wheel average rotation speed that is an average rotation speed of left and right rear wheels, based on a rotation speed of a second motor. When a difference between the front wheel average rotation speed and the rear wheel average rotation speed is larger than a first reference value, the motor vehicle sets a vehicle body speed, based on the lower between the front wheel average rotation speed and the rear wheel average rotation speed. The motor vehicle compares a difference between the vehicle body speed and the wheel speed of each wheel, with a second reference value and thereby determines whether the wheel idles.
