Differential limiting control apparatus for a vehicle and the method thereof

A clutch torque computing unit calculates a final clutch torque by changing the ratio of the clutch torques obtained through feedback control and feed forward control according to the diameter difference of a tire calculated by a tire diameter difference computing unit. A feedback control clutch torque computing unit calculates the clutch torque of a clutch unit based on vehicle behaviors through feedback control. A feed forward control clutch torque computing unit calculates the clutch torque based on behaviors through feed forward control. An independent claim is also included for a differential limiting control method.
