Abstract

A drive force control system capable of stabilizing behavior of a vehicle with a rapid control response. The drive force control system for a vehicle having a pair of front wheels and a pair of rear wheels includes: a distribution mechanism, which distributes power outputted from a prime mover to a right wheel and to a left wheel of any one of the pairs of front and rear wheels, and which changes a ratio to distribute the power to the right wheel and the left wheel by engaging or disengaging an engagement mechanism; and at least two motors arranged individually for a right wheel and a left wheel of other pair of wheels to control drive forces for driving those right wheel and left wheel individually.
