To provide a turn control device of a vehicle which can control turning performance of the vehicle optimally while preventing each wheel from diverging tire force.SOLUTION: A turn control device of a vehicle controls turning performance of the vehicle which includes a brake drive source capable of controlling brake drive torque of respective wheels independently. The turn control device comprises yaw moment command value calculation means 17 and torque distribution calculation means 18 which includes a demand load factor calculation part 20 which calculates demand load factors to be demanded of respective wheels through either of one or both of accelerator/brake operation and steering. The torque distribution calculation means 18 controls distribution of accelerator/brake torque command values Tab through the accelerator/brake operation according to magnitude relation of the demand load factors of the respective wheels calculated at the demand load factor calculation part 20 and allowable load factors which are load factors up to which the respective wheels can allow and torque command values Ts after feedback control calculated at the yaw moment command value calculation means 17.SELECTED DRAWING: Figure 3

    【課題】各車輪のタイヤ力の発散を防止すると共に車両の旋回性能を最適に制御することができる車両の旋回制御装置を提供する。【解決手段】車両の旋回制御装置は、各車輪の制駆動トルクを独立に制御可能な制駆動源を有する車両の旋回特性を制御する。旋回制御装置は、ヨーモーメント指令値計算手段17と、アクセル・ブレーキ操作および操舵のいずれか一方または両方により各車輪に要求する要求負荷率を計算する要求負荷率計算部20を有するトルク配分計算手段18とを備える。トルク配分計算手段18は、要求負荷率計算部20で計算された各車輪の要求負荷率と、各車輪が許容できる負荷率である許容負荷率との大小関係に応じて、アクセル・ブレーキ操作によるアクセル・ブレーキトルク指令値Tabと、ヨーモーメント指令値計算手段17で計算された前記フィードバック制御後のトルク指令値Tsとの配分を制御する。【選択図】図3
