Abstract
A right-left driving force control system includes: a selecting unit which: selects an adjusting unit adjusting distribution of a driving force between right and left wheels, when a shifting direction in which the driving force is shifted between the wheels and which is related to a control amount is the same as a first direction towards one of the wheels which has a larger speed; selects a limiting unit adjusting a differential action limiting force, when the shifting direction is the same as a second direction towards one of the wheels which has a smaller speed, and a difference between the wheel speeds is equal to or larger than a threshold value; and maintains the adjusting unit or the limiting unit, which has been selected, when the shifting direction is the same as the second direction, and the difference between the wheel speeds is less than the threshold value; and a control unit which controls the adjusting unit or the limiting unit, which is selected or maintained by the selecting unit, based on the control amount.
