PROBLEM TO BE SOLVED: To provide a configuration of using both tire force control and aerodynamic control for controlling the motion of a vehicle, in which the action of actual aerodynamic force generated by a lateral wind to a vehicular body is cancelled or suppressed, with a novel configuration for distributing a component of the lateral wind disturbance using a variation frequency of the component so that the tire force control and aerodynamic control cancel or suppress each other in consideration of the response of the aerodynamic control.SOLUTION: A vehicular motion control apparatus includes: first control means for applying tire force in a direction of reducing a component of a variation frequency that is higher than a given frequency of actual aerodynamic force generated in a vehicular body by an airflow exerted thereto; and second control means for applying control aerodynamic force that exerts to the vehicular body in a direction of reducing a component of a variation frequency that is lower than a given frequency of the actual aerodynamic force. Here, the given frequency may be set on the basis of a delay in a phase of the control aerodynamic force in relation to the actual aerodynamic force.SELECTED DRAWING: Figure 1
【課題】 車体に対して横風により発生する実空気力の作用を相殺又は抑制する車両の運動制御のためにタイヤ力制御と空力制御とを併用する構成に於いて、空力制御の応答性を考慮して、タイヤ力制御と空力制御とがそれぞれ相殺又は抑制を図る横風外乱の成分をその変動周波数によって分配する構成を提供すること。【解決手段】 本発明の車両運動制御装置は、車体が受ける空気流によって車体に発生する実空気力の所定の周波数よりも高い変動周波数の成分を低減する方向にタイヤ力を付与する第一の制御手段と、実空気力の所定の周波数よりも低い変動周波数の成分を低減する方向に前記車体に作用する制御空気力を付与する第二の制御手段とを含む。所定の周波数は、実空気力に対する制御空気力の位相の遅れに基づいて設定されてよい。【選択図】 図1
