A driving force distribution control unit 60 calculates front/rear driving force distribution cooperative control addition yaw moment by multiplying front/rear driving force distribution control addition yaw moment by a front/rear driving force distribution cooperative control gain. Under steering accelerating condition, when it is possible to judge that actual lateral acceleration is high and the road is a high .mu. road, the front/rear driving force distribution cooperative control gain is set to become a low control gain so as to reduce a control amount by the front/rear driving force distribution control operation. Also, the driving force distribution control unit 60 calculates right/left driving force distribution cooperative control addition yaw moment by multiplying right/left driving force distribution control addition yaw moment by a right/left driving force distribution cooperative control gain. Under steering accelerating condition, when it is possible to judge that actual lateral acceleration is low and the road is a low .mu. road, the right/left driving force distribution cooperative control gain is set to become a low control gain so as to reduce a control amount by the right/left driving force distribution control operation.
