Abstract

In the case where a difference between rotational speeds of right and left wheels detected by wheel speed sensors is less than a predetermined value, a right and left wheel power transmission control section distributes driving force between the right and left wheels so that a total value of the driving force of the right and left wheels does not exceed a limit value set up by a front and rear wheels power transmission control section. In the case where the difference between the rotational speeds of the right and left wheels is the predetermined value or more, the right and left wheel power transmission control section transmits the driving force up to a driving force upper limit for each wheel to the respective right and left rear wheels regardless of the total value of the driving force of the right and left rear wheels.
