<p><P>PROBLEM TO BE SOLVED: To provide a wheel driving force distribution control system which improves fuel consumption performance. <P>SOLUTION: With this wheel driving force distribution control system 90, the changeover to two-wheel drive is automatically performed in the case start/stop is repeated due to traffic congestion. Engine load is thereby reduced, and fuel consumption performance is improved. Furthermore, if a slip occurs due to starting with two-wheel drive, the changeover to four-wheel drive is performed, so that congestion on a rough road can be dealt with. In the case of no congestion, transmission torque by a torque transmission device 30 is determined on the basis of throttle opening m and the rotating speed difference▵N of front and rear wheels 14, 15, and appropriate driving force distribution is performed between the front and rear wheels 14, 15, so that various situations can be dealt with. <P>COPYRIGHT: (C)2004,JPO</p> |
