Abstract
An ECU of a four wheel drive vehicle controls a transmission torque of a driving force transmission apparatus provided between a rear differential and a left rear wheel. The ECU includes a first computation unit that computes a command torque to be transmitted to the left rear wheel by the driving force transmission apparatus, based on a traveling state of the four wheel drive vehicle; and a second computation unit that corrects the command torque computed by the first computation unit, if a difference between rotation speeds of a pair of side gears of the rear differential is larger than or equal to a predetermined value.
