Abstract
In a vehicular driving force distribution system, a left or right torque distribution clutch is selectively engaged to lock a carrier member or a sun gear of a planetary gear mechanism, whereby torque can be distributed between left and right wheels. Also, if a differential limitation clutch is engaged to control relative rotation of the sun gear and the carrier member of the planetary gear mechanism, the planetary gear mechanism enters a locked state, so that the left and right wheels are integrated to perform differential limitation. By the arrangement of merely providing the differential limitation clutch, the differential limitation can be performed by simple control and moreover the control response is improved, as compared with the case where differential limitation is performed by controlling engagement forces of the left and right torque distribution clutches.
