To provide a vehicle motion control device which suppresses vehicle jolt at an occurrence time of a deceleration factor of an own vehicle.SOLUTION: A vehicle motion control device includes: a first target speed/acceleration calculation section which calculates first target speed/acceleration on the basis of a travel route of an own vehicle including a curve; a second target speed/acceleration calculation section which calculates second target speed/acceleration on the basis of other factors other than the factor for curving the travel route; and a third target speed/acceleration calculation section which calculates third target speed/acceleration to be a command value during traveling of the own vehicle. The third target speed/acceleration calculation section generates a speed/acceleration plan until the own vehicle reaches the other factors or a speed/acceleration plan until the own vehicle reaches a prescribed position determined on the basis of the other factors on the basis of the first target speed/acceleration and the second target speed/acceleration, and changes a calculation method of the third target speed/acceleration on the basis of an evaluation result of the speed/acceleration plans.SELECTED DRAWING: Figure 1 【課題】 自車両の減速要因発生時に車両揺れを抑える車両運動制御装置を提供する。【解決手段】 曲がりを含む自車両の走行経路に基づいて第１目標速度・加速度を算出する第１目標速度・加速度算出部と、前記走行経路を曲げる要因以外の他の要因に基づいて第２目標速度・加速度を算出する第２目標速度・加速度算出部と、自車両の走行時の指令値である第３目標速度・加速度を算出する第３目標速度・加速度算出部と、を備え、前記第３目標速度・加速度算出部は、前記第１目標速度・加速度と前記第２目標速度・加速度に基づいて、前記他の要因に前記自車両が到達するまでの間の速度・加速度計画、または、前記他の要因に基づいて決定される所定の位置に前記自車両が到達するまでの間の速度・加速度計画を生成し、前記速度・加速度計画の評価結果に基づいて、前記第３目標速度・加速度の算出方法を変更する車両運動制御装置。【選択図】 図１
