PROBLEM TO BE SOLVED: To provide a vehicle posture control device which can stabilize a vehicle posture without imparting incongruity to a driver, in a four-wheel drive vehicle in which brake/drive forces are individually imparted to wheels.SOLUTION: This vehicle posture control device 24 is arranged at a vehicle control device 10 of a four-wheel drive vehicle, and comprises: criterion yaw rate calculation means 25; a yaw rate sensor 22; target yaw moment calculation means 26; brake/drive force command means 15; and yaw moment control means 27. The yaw moment control means 27 has distribution ratio change means 27a which continuously changes a fore-and-aft distribution ratio of yaw moment control torque distributed to fore-and-aft wheel 3, 2 according to an actual yaw rate when the actual yaw rate which is detected by a yaw rate sensor 22 is within a specified range in which positive/negative values of a code of the actual yaw rate are inverted.SELECTED DRAWING: Figure 1

    【課題】 各輪に制駆動力をそれぞれ個別に与える四輪駆動車両において、運転者に違和感を与えることなく車両姿勢の安定化を図ることができる車両姿勢制御装置を提供する。【解決手段】 この車両姿勢制御装置24は、四輪駆動車両を制御する車両制御装置10に設けられ、規範ヨーレート演算手段25と、ヨーレートセンサ22と、目標ヨーモーメント演算手段26と、制駆動力指令手段15と、ヨーモーメント制御手段27とを備える。ヨーモーメント制御手段27は、ヨーレートセンサ22で検出される実ヨーレートにつき、この実ヨーレートの符号の正負が反転する定められた範囲のとき、前記検出される実ヨーレートに応じて前後輪3,2に配分するヨーモーメント制御トルクの前後配分比率を連続的に変化させる配分比率変化手段27aを有する。【選択図】 図1
