Abstract

A device for controlling the distribution of drive force includes a driven wheel drive force distribution reference command value calculator configured to determine a driven-wheel-oriented drive force distribution reference command value from the estimated value of the drive force sent to the drive wheels and a drive force reference distribution ratio, and a driven wheel drive force distribution command value calculator configured to determine a driven-wheel-oriented drive force distribution command value by correcting the driven wheel drive force distribution reference command value by a correction amount that differs between the electric motor operating mode and the electric motor non-operating mode, and to make the correction amount for the electric motor operating mode greater than the correction amount for the electric motor non-operating mode.
