To relax an understeer tendency of a vehicle attitude over a wide range of a vehicle speed range.SOLUTION: A controller 100 sets first distribution torque, which is distribution torque to a rear wheel 12R, based on a target yaw rate, and sets second distribution torque, which is distribution torque to the rear wheel 12R, based on a target lateral G. The controller 100 sets the first distribution torque, which is distribution torque to the rear wheel 12R, based on a first gain in a low speed region where a vehicle speed sensor value detected by a vehicle speed sensor 43 is less than a predetermined vehicle speed, and controls a coupling 28 based on the first distribution torque. On the other hand, the controller 100 sets the second distribution torque, which is distribution torque to the rear wheel 12R, based on a second gain in a high speed region where the vehicle speed sensor value is equal to or higher than the predetermined vehicle speed, and controls the coupling 28 based the second distribution torque.SELECTED DRAWING: Figure 2

    【課題】広範囲の車速域にわたって、車両姿勢がアンダーステア傾向になることを緩和する。【解決手段】コントローラ100は、目標ヨーレートに基づいて後輪12Rへの分配トルクである第1分配トルクを設定し、且つ、目標横Gに基づいて後輪12Rへの分配トルクである第2分配トルクを設定する。コントローラ100は、車速センサ43が検知した車速センサ値が所定車速未満の低速領域では、第1ゲインに基づいて後輪12Rへの分配トルクである第1分配トルクを設定し、この第1分配トルクに基づいてカップリング28を制御する。一方、コントローラ100は、車速センサ値が所定車速以上の高速領域では、第2ゲインに基づいて後輪12Rへの分配トルクである第2分配トルクを設定し、この第2分配トルクに基づいてカップリング28を制御する。【選択図】図2
