Abstract:
A driving force control apparatus of a motor vehicle including a first set of drive wheels and a second set of drive wheels which are driven with respective driving forces that are controlled independently of each other, comprising:a slip rate difference calculating unit configured to calculate an actual slip rate difference between a slip rate of the first set of drive wheels and a slip rate of the second set of drive wheels, wherein the sliprate sr is defined by: sr=(nfâˆ’nr)nh, where nf is the rotation speed of the first set of drive wheels, nr is the rotation speed of the second set of drive wheels and nh is the greater value of nf and nr; and a driving force distribution control unit configured to control distribution of driving force between the first set of wheels and the second set of wheels, based on the slip rate difference calculated by the slip rate difference calculating unit.
