<P>PROBLEM TO BE SOLVED: To provide a driving force distribution control device for a front and rear wheels drive vehicle, which achieves preferable driving performance on the occurrence of vibrations in a drive-train. <P>SOLUTION: The control device executes a control to reduce a transmission torque of an electronic control coupling 26, and also controls the operation of the electronic control coupling 26 so as to increase the transmission torque to be larger than an estimate value T<SB POS="POST">RO</SB>of a road surface transmission torque of a rear wheel 32 when detecting vibrations of the drive-train including the rear wheel 32. Accordingly, a necessary and sufficient torque is transmitted to the rear wheel 32 side as a sub-drive wheel, thereby preferably suppressing an occurrence of slips of a front wheel 22 as a main drive wheel. As a result, the driving force distribution control device for the front and rear wheels drive vehicle 8 that achieves the preferable driving performance on the occurrence of vibrations in the drive-train, is obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
