PURPOSE:To aim at improvement in stack escapability as well as improvement in accelerability at a low friction factor passage, by installing a device which interlocks the clutch clamping force control actuation of a differential limiting controller with the clutch clamping force control actuation of an all wheel driving force distribution controller. CONSTITUTION:An all wheel driving force distribution controller 1 makes clutch clamping force variable according to driving conditions of a vehicle, and clutch clamping force control actuation of this controller 1 and another clutch clamping force control actuation of a differential limiting controller are interlocked with each other via an interlocking device 3. This clutch clamping force of the differential limiting controller 2 is given as the value conformed to the clutch clamping force of the all wheel driving force distribution controller 1. With this constitution, when it comes to driving force distribution at the 4WD side, differential limiting actuation is also performed by the interlocking device 3, increasing driving force at the low speed side of left and right wheels. Therefore, stack escapability and accelerability at a low friction factor passage are all improved.
