<p><P>PROBLEM TO BE SOLVED: To enable distribution of output of a driving source to driven wheels while suppressing increase in driving loss caused by distribution of the output of the driving source to the driven wheels in a four-wheel drive vehicle, thereby enabling suppression of deterioration in fuel consumption during four-wheel driving. <P>SOLUTION: In a control system of a four-wheel-drive vehicle having a drive-force distributing unit 28, which distributes the output of the driving source 14 to main driving wheels 12F and driven wheels 12R, in the case that the amount of slipping of the main driving wheels is equal to or higher than a predetermined amount, a distribution control unit 34 controls actuation of the driving-force distributing unit so as to increase distribution of the output of the driving source to the driven wheels when it is determined that the drive loss of the main driving wheels is larger than the drive loss caused by distribution of the output of the driving source to the driven wheels, and so as to reduce distribution of the output of the driving source to the driven wheels when it is determined that the drive loss of the main driving wheels is smaller than the drive loss caused by distribution of the output of the driving source to the driven wheels. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
