PROBLEM TO BE SOLVED: To provide a vehicular flow straightening device that can respond to change of an air current condition.SOLUTION: A flow straightening device 10 includes: an upper plate 14 extendable from a ceiling end of a vehicle rear surface 12 to the rear side of the vehicle; and a lower plate 16 expandable from a floor end of the vehicle rear surface 12 to the rear side of the vehicle. The flow straightening device further includes: actuators 18A, 18B for adjusting extending length of the upper plate 14 and the lower plate 16; an upper pressure sensor 20A relatively provided on the ceiling side of the vehicle rear surface 12; and a lower pressure sensor 20B relatively provided on the floor side of the vehicle rear surface 12. In addition, the flow straightening device includes a control section 24 for receiving pressure values detected by the upper and lower pressure sensors 20A, 20B and adjusting the extending length of the upper plate 14 and the lower plate 16 via the actuators 18A, 18B, so as to reduce a difference between the pressure values detected by the upper pressure sensor 20A and the lower pressure sensor 20B.SELECTED DRAWING: Figure 1
【課題】気流条件の変化に対応可能な車両用の整流装置を提供する。【解決手段】整流装置10は、車両後面12の天井端から車両後方に延伸可能な上部板14と、車両後面12の床端から車両後方に延伸可能な下部板16と、を備える。さらに、上部板14及び下部板16の延伸長さを調整するアクチュエータ18A,18B、車両後面12の、相対的に天井側に設けられた上部圧力センサ20A、及び、車両後面12の、相対的に床側に設けられた下部圧力センサ20Bを備える。さらに、上部及び下部圧力センサ20A,20Bが検出した圧力値を受信するとともに、上部圧力センサ20Aと下部圧力センサ20Bの圧力値の差を縮めるように、アクチュエータ18A,18Bを介して上部板14及び下部板16の延伸長さを調整する、制御部24を備える。【選択図】図1
