To provide drive control technique of a front/rear wheel drive vehicle capable of optimizing outputs of front/rear drive wheels according to a driving state of a vehicle, reducing affection applied to steering by drive force applied to a steering wheel, and achieving smooth and stable operation.SOLUTION: A drive control system 80 of a front/rear wheel drive vehicle 10 is a drive control system provided on a two-wheel barrow which is a front/rear wheel drive vehicle comprising drive wheels on a front wheel 11 and a rear wheel 12, in which one drive wheel is a steering wheel and which travels by shifting a tire ground contact point to inside of a turning direction relative to a steering shaft center when a vehicle body is inclined to any of left/right sides in turning of the vehicle. The drive control system 80 is configured so that, when the vehicle 10 is in a banking state, a target drive torque of the steering wheel to an accelerator operation amount in acceleration operation of an operator is reduced, and a reduction width is increased as an accelerator opening degree is increased, compared with when the vehicle 10 is in a straight travel state.SELECTED DRAWING: Figure 1
【課題】車両の運動状態に応じて前後駆動輪の出力を最適化し、操舵輪に加わる駆動力が操舵に及ぼす影響を小さくして、スムーズで安定した操作を可能とした前後輪駆動車両の駆動制御技術を提供する。【解決手段】本発明に係る前後輪駆動車両10の駆動制御システム80は、前輪11と後輪12とに駆動輪を有し、一方の駆動輪が操舵輪である前後輪駆動車両で、車両の旋回時に車体が左右何れかに傾斜した際にタイヤ接地点をステアリング軸中心よりも旋回方向内側に移して走行する二輪車に設けられる駆動制御システムであって、前記駆動制御システム80は、前記車両10がバンク状態にある場合では、車両10が直立走行状態にある場合に較べて、運転員の加速操作時のアクセル操作量に対する前記操舵輪の目標駆動トルクを低減させ、アクセル開度が大きくなるにつれ低減幅が大きくなる制御が行われることを特徴とするものである。【選択図】 図1
