  "textContent": "A calculating section 43 finds a left-right rear wheel drive force difference transient control computation value dd TcLR, which is a basic target value for a turning response transiently requested by a driver through a steering speed at current wheel speeds Vw (vehicle speed). A computing section 45 finds a left-right drive force difference transient control gain ± based on a target yaw rate change rate dtÆ such that the control gain ± is smaller than 1 in a high target yaw rate change rate region. The computing value dd TcLR is multiplied by the control gain ± to calculate a left-right rear wheel drive force difference transient control amount d TcLR and the same control amount is contributed to a left-right wheel drive force distribution control. As a result, during high-speed steering when the yaw rate gain tends to increase, the left-right drive force difference transient control amount is revised to a decreased value such that the transient control amount causes less of an increase in the yaw rate. In this way, the vehicle behavior can be prevented from becoming unstable.",
