To provide a turn control device of a vehicle that can always and appropriately assist the turning of a vehicle by correcting a target driving force according to the pneumatic pressure and degree of deterioration of wheels.SOLUTION: A turn control device 20 of a vehicle 1 comprises: a target yaw rate calculation unit 21 for calculating a target yaw rate based on an actual steering angle, actual wheel speed, and actual lateral acceleration; a target driving force control amount calculation unit 22 for calculating a target driving force control amount of a driving source 2 based on the target yaw rate; a pneumatic pressure sensor 18 for detecting pneumatic pressure of wheels WFL, WFR, WRL, WRR; and correction units 25, 26 for correcting the target driving force control amount. The correction units 25, 26 discriminate between an inner wheel and an outer wheel at the time of turning of the vehicle from at least one of the actual steering angle, the actual yaw rate, and the actual lateral acceleration, and correct the target driving force control amount so that a target driving force becomes smaller as the pneumatic pressure of the inner wheel detected by the pneumatic pressure sensor 18 is smaller than a predetermined value.SELECTED DRAWING: Figure 2

    【課題】車輪の空気圧や劣化度合いに応じて目標駆動力を補正することによって、車両の旋回を常に適正にアシストすることができる車両の旋回制御装置を提供すること。【解決手段】実舵角と、実車輪速と、実横加速度に基づいて目標ヨーレートを算出する目標ヨーレート算出部21と、目標ヨーレートに基づいて駆動源2の目標駆動力制御量を算出する目標駆動力制御量算出部22と、車輪WFL,WFR,WRL,WRRの空気圧を検出する空気圧センサ18と、目標駆動力制御量を補正する補正部25,26と、を備える車両1の旋回制御装置20において、補正部25,26は、実舵角、実ヨーレートまたは実横加速度の少なくとも1つから車両旋回時の内輪と外輪を判別し、空気圧センサ18によって検出される内輪の空気圧が所定値より小さいほど目標駆動力が小さくなるように目標駆動力制御量を補正する。【選択図】図2
