To provide a driving force control device of a vehicle, capable of controlling driving force in consideration of the change of parameters of the vehicle without detecting the change of the parameters of the vehicle.

In the driving force control device of a vehicle having a control for improving turning property for controlling the driving force on the basis of a control amount for making a stability factor of the vehicle follow a target value and a requested acceleration requested to the vehicle, the device includes a vehicle performance estimation means (step S1) for estimating a vehicle performance based on the parameters of the vehicle changed within a prescribed range, and a determination means (step S2) for determining whether or not a predetermined vehicle performance can be obtained by the vehicle performance estimated by the vehicle performance estimation means. When it is determined by the determination means that the predetermined vehicle performance cannot be obtained, the control for improving turning property is not executed.
