Abstract
A driving force control apparatus is provided for a vehicle capable of preventing a shock from being generated by disengaging a clutch disposed between a subordinate drive source and subordinate drive wheels during vehicle travel. When a transition determination is made in which the clutch will be released, e.g., from a four-wheel drive state to a two-wheel drive state, a clutch release section disengage the clutch, upon the drive torque of the drive source substantially reaching a target drive torque in which a difference between an output torque of the clutch and an input torque of the clutch is smaller than a prescribed value in response to the transition determination.
