Claim Text:
1. A driving force control apparatus, which is to be applied to a four-wheel drive vehicle comprising front left and right wheels and rear left and right wheels each having a tire and comprising a driving force application apparatus configured to apply driving forces to the four wheels independently of one another, and which is configured to control the driving forces to be applied to the four wheels by controlling the driving force application apparatus, the driving force control apparatus comprising: an apparatus configured to acquire information on vehicle body speeds at positions of the four wheels; an apparatus configured to acquire information on vertical loads of the four wheels; and an apparatus configured to acquire information on a driving force required by a driver to the four-wheel drive vehicle, wherein the driving force control apparatus is configured to calculate target driving forces for the four wheels required to set tire sliding vectors of the four wheels to be the same as one another based on the vehicle body speeds at the positions of the four wheels, the vertical loads of the four wheels, and the driving force required by the driver, and to control the driving force application apparatus such that the driving forces of the four wheels are equal to the corresponding target driving forces, respectively.
