PROBLEM TO BE SOLVED: To provide a turn control device of a vehicle in which yaw moment control for improving turn performance functions, and which can stably maintain a vehicle posture even in a place or the like which is low in a road face friction coefficient, in the vehicle having a brake drive source which can independently control a brake drive force being a brake force or a drive force of a wheel.SOLUTION: This turn control device of a vehicle includes: first road face friction coefficient calculation means 22; second road face friction coefficient calculation means 25; control gain calculation means 23; target yaw rate calculation means 21; target yaw rate correction means 27; first brake drive force calculation means 24; and second brake drive force calculation means 28. A magnitude of a second road face friction coefficient μ2 is smaller than or equal to a magnitude of a first road face friction coefficient μ1 since the brake drive force of each wheel is not taken into consideration. Brake drive force command value calculation means 29 calculates a brake drive force command value from a brake drive force FA and a brake drive force FB which are calculated by using the first and second road face friction coefficients μ1, μ2.SELECTED DRAWING: Figure 3
【課題】各車輪の制動力または駆動力である制駆動力を独立に制御可能な制駆動源を有する車両において、旋回性能を向上させるヨーモーメント制御が機能し、かつ路面摩擦係数が低い場所等でも車両姿勢を安定に保つことができる車両の旋回制御装置を提供する。【解決手段】この車両の旋回制御装置は、第1路面摩擦係数計算手段22、第2路面摩擦係数計算手段25、制御ゲイン計算手段23、目標ヨーレート計算手段21、目標ヨーレート補正手段27、第1制駆動力計算手段24、第2制駆動力計算手段28を含む。第2の路面摩擦係数μ2は、各車輪2の制駆動力を考慮しないため、大きさが第1の路面摩擦係数μ1の大きさに比べて小さいか等しい。制駆動力指令値計算手段29は、それぞれ第1、第2の路面摩擦係数μ1、μ2を用いて計算した制駆動力FAおよび制駆動力FBから制駆動力指令値を計算する。【選択図】図3
