Claim Text:
1. A driving force distribution control apparatus for a four-wheel drive vehicle including a driving force transmission path via which a driving force generated by a drive source is transferred to primary drive wheels and secondary drive wheels, and a driving force distribution apparatus disposed in the driving force transmission path between the drive source and the secondary drive wheels, the driving force distribution control apparatus comprising: a basic distribution determination device configured to determine basic distribution of the driving force to the secondary drive wheels in accordance with the driving force and driving conditions of the vehicle, the basic distribution determination device comprising: a servo controller configured to correct the driving force provided to the secondary drive wheels according to the basic distribution determined by the basic distribution determination device using a deviation between a measured value and a normative value of a rotational difference between an input shaft and an output shaft of the driving force distribution apparatus.
