Abstract
A driving force distribution control system for a four-wheel drive vehicle is provided. The four-wheel drive vehicle uses front wheels as main driving wheels, and when a towed vehicle is coupled to a coupling part provided to a rear part of the four-wheel drive vehicle, the towed vehicle has the center of gravity position so that a downward load in a vehicle up-and-down direction is applied to the rear part of the vehicle through the coupling part. A driving force distribution control device includes a towing determination module configured to determine whether the vehicle is towing the towed vehicle, and when it is determined that the vehicle is towing the towed vehicle, a driving force distribution control device controls the driving force distributing device so that the driving force distributing amount to rear wheels becomes larger than that when the four-wheel drive vehicle is not towing the towed vehicle.
