Description

例えば上記した実施形態においては、走行状態値、車両環境値等の検出値に基づいて剥離点を制御することとしたが、これに限られるものではなく、車両の走行中において常時、開口部の所定の位置を吸引すると共に開口部の所定の位置から気体の吐出を行うこととしてもよい。一般的に車両走行中は車速の揺らぎや横風の影響等により、剥離点は図７（ａ）に示されるように常時移動している。そしてこれが走行中の車両のふらつきにつながることが予測される。一方で本開示において、車両の走行中において常時、開口部の所定の位置を吸引すると共に開口部の所定の位置から気体の吐出を行うことにより、剥離点を定常化することにより車両の安定化を向上させることが可能となると予測される。例えば図７（ｂ）に示される複数のチャンバＣ１～Ｃ６のうち、チャンバＣ１～Ｃ３に対応する開口部を吸引、チャンバＣ４に対応する開口部を吐出、チャンバＣ５～Ｃ６に対応する開口部を停止とした場合、剥離点の移動距離は図７（ａ）よりも短くなり、その結果、走行中の車両１００のふらつきを低減することが可能となる。 For example, in the embodiment described above, the separation point is controlled based on the detected values such as the driving state value and the vehicle environment value, but the separation point is not limited to this. Gas may be discharged from a predetermined position of the opening while suction is applied to a predetermined position. Generally, while the vehicle is running, the separation point is constantly moving as shown in FIG. 7(a) due to fluctuations in vehicle speed, the influence of crosswinds, and the like. It is predicted that this will lead to swaying of the vehicle while it is running. On the other hand, in the present disclosure, the vehicle is stabilized by stabilizing the separation point by constantly suctioning a predetermined position of the opening and discharging gas from a predetermined position of the opening while the vehicle is running. It is predicted that it will be possible to improve the For example, among the plurality of chambers C1 to C6 shown in FIG. 7(b), the openings corresponding to chambers C1 to C3 are for suction, the openings corresponding to chamber C4 are for ejection, and the openings corresponding to chambers C5 to C6 are for suction, and the openings corresponding to chambers C5 to C6 are When the vehicle 100 is stopped, the moving distance of the separation point becomes shorter than that shown in FIG. 7(a), and as a result, it is possible to reduce the wobbling of the vehicle 100 while it is running.
