A left-right drive force difference transient control computation value calculating section uses a map search, based on a change rate of a target yaw rate, to find a left-right rear wheel drive force difference transient control computation value, which is a basic target value for a turning response transiently requested by a driver. A left-right drive force difference transient control gain computing section sets a left-right drive force difference transient control gain to be smaller than 1 in a low vehicle speed region. A transient control computing section multiplies the left-right rear wheel drive force difference transient control computing value by the left-right drive force difference transient control gain to calculate a left-right rear wheel drive force difference transient control amount and contributes the same to a left-right wheel drive force distribution control.
