Abstract
Provided is a driving force control device for a four-wheel-drive vehicle that can evade an occurrence of excessive understeer and oversteer in situations unintended by the driver, by appropriately controlling driving forces to be distributed to sub-drive wheels. The driving force distribution device of the four-wheeled vehicle controls driving force to be distributed to the rear wheels (Wr, Wr) by the clutch () for front-and-rear torque distribution so that the wheels (Wf, Wf) are main drive wheels and the rear wheels (Wr, Wr) are sub-drive wheels. The driving force distribution device is adapted to perform control to restrict the upper limit of the four-wheel drive torque based upon an estimated driving force and steering angle of the vehicle, when calculating four-wheel drive torque to be distributed to the rear wheels (Wr, Wr) by the driving force distribution device ().
