  "textContent": "A rear wheel drive force difference setting gain Gain is multiplied by a basic left-right rear wheel drive force difference steady-state control computation value for achieving a vehicle turning behavior steadily requested by a driver in order to calculate a final left-right rear wheel drive force difference steady-state control amount. The final left-right rear wheel drive force difference steady-state control amount is added to a left-right rear wheel drive force difference transient control amount to obtain left-right rear wheel rear wheel drive force difference. The left-right rear wheel drive force difference is multiplied by feedback control coefficient to obtain a final rear wheel drive force difference TcLR. During an initial stage of turning in which a lateral acceleration Gy is smaller than a turn initial stage determining value Gys, the rear wheel drive force difference setting gain Gain is set to A, which is larger than 1 and increases as the lateral acceleration Gy decreases. As a result, the final rear wheel drive force difference TcLR is increased during the initial stage of turning (lateral acceleration Gy < Gys) and an initial turning response can be improved.",
