The differential limiting control apparatus having a clutch unit
interposed between one rotational shaft and the other rotational shaft
for variably transmitting a driving force between the one rotational
shaft and the other rotational shaft, having: a feedback control unit for
computing the clutch torque on basis of vehicle behaviors through a
feedback control, a feed forward control unit for computing the clutch
torque based on the behaviors through feed forward control, a tire
diameter difference computing unit for computing a diameter difference of
a tire, and a clutch torque computing unit for computing a final clutch
torque by changing a ratio of the clutch torque obtained through the
feedback control and a clutch torque obtained through the feed forward
control so as to appropriately decide the feed forward control by
effectively suppressing the tire slip while avoiding the occurrence of
the internal circulation of the torque.
