PROBLEM TO BE SOLVED: To provide a driving force distribution control device of a vehicle, which allows for quick change of the distribution of driving force according to the running state of the vehicle, thereby achieving improvement in fuel economy and running stability.SOLUTION: The driving force distribution control device of a vehicle is provided that has a center clutch for distributing driving force to a front wheel side and a rear wheel side, and right and left axle clutches interposed between a final reduction gear device on the front wheel side or the rear wheel side and right and left drive shafts. The driving force distribution control device comprises: a road surface state determination part for determining a road surface state on the basis of the road surface friction coefficient of a running road; and a drive mode setting part for setting, according to the road surface state, either one of drive modes which include a two wheel drive mode of releasing the center clutch and the right and left axle clutches together, an all wheel drive mode of engaging the center clutch and the right and left axle clutches together, and a standby mode of releasing either one of the center clutch and the right and left axle clutches and engaging the other.SELECTED DRAWING: Figure 6
