To improve drivability when lateral acceleration is great.SOLUTION: The front wheel driving force distributed to a front wheel 8 can be calculated on the basis of a front wheel basic torque calculated according to the travel state of a vehicle 1 and a front wheel correction torque calculated according to lateral acceleration of the vehicle 1. The front wheel correction torque is calculated on the basis of a deviation between a detected yaw rate and a target yaw rate and a gain set to be greater as the lateral acceleration is greater. The vehicle 1 can reduce a behavior change of the vehicle 1 and improve the drivability in a region where the lateral acceleration is great.SELECTED DRAWING: Figure 1

    【課題】横加速度が大きいときの運転性を向上させる。【解決手段】前輪8に配分される前輪駆動力は、車両1の走行状態に応じて算出される前輪基本トルクと、車両1の横加速度に応じて算出される前輪補正トルクと、に基づいて算出可能となっている。前輪補正トルクは、検出されたヨーレートと目標ヨーレートの偏差と、横加速度が大きいほど大きくなるよう設定されたゲインと、に基づいて算出される。車両1は、横加速度が大きい領域において、車両1の挙動変化を小さくでき、運転性を向上させることができる。【選択図】図1
