Abstract
A driving force distribution control device for a four wheel drive vehicle having a mechanism that distributes the torque of an engine, which is transmitted to a main drive wheel, to a secondary drive wheel determines a first torque to be distributed to the secondary drive wheel on the basis of the engine torque, and corrects the determined first torque on the basis of a yaw rate deviation between a target yaw rate and an actual yaw rate of the vehicle. When an absolute value of the yaw rate deviation is equal to or greater than a predetermined value, the mechanism is controlled on the basis of the corrected torque.
