To provide a reverse travel detection device capable of rapidly and correctly detecting presence/absence of a reverse travel in addition to a front/rear side of a road sign even in a rough weather.SOLUTION: A reverse travel detection device performs: irradiating a road sign in front of a self vehicle with a millimeter wave from a millimeter wave radar; determining whether a surface of the road sign irradiated with the millimeter wave is a front surface or a rear surface based on a reflection wave signal from the road sign; and determining whether the self vehicle is performing a reverse travel on a road based on a determination result on a front/rear side of the road sign.SELECTED DRAWING: Figure 4

    【課題】悪天候であっても、道路標識の表裏、引いては、逆走の有無を早期かつ正確に検出することができる、逆走検出装置を提供する。【解決手段】本発明に係る逆走検出装置は、その一態様として、自車両の前方の道路標識に対してミリ波レーダからミリ波を照射し、前記道路標識からの反射波信号に基づき、ミリ波を照射した前記道路標識の面が表であるか裏であるかを判別し、前記道路標識の表裏の判別結果に基づき、自車両が道路を逆走しているか否かを判定する。【選択図】図4
