PROBLEM TO BE SOLVED: To allow information from road signs to be more surely transmitted to drivers.SOLUTION: A sign recognition system includes: display means 11 for conducting a warning display about road signs with respect to drivers; road sign detection means (an out-vehicle camera 4) that detects the road signs existing forward; detection means (in-vehicle camera 7) that detects a visual recognition direction of the driver; and control means U. The control means U is configured to, when the direction of the detected road sign and the detected visual recognition (viewing line) direction of the driver are different, control warning information about the detected road sign to be displayed on the display means 11 assuming the driver does not watch the road sign, and in the meantime, when the two directions agree with each other, cause the waring display not to be conducted. In a situation where visibility of the road sign gets worsen such as when travelling through a tunnel, at a night time or snow falling, the warning display is conducted with respect to the display means 11 regardless of the visual recognition direction of the driver.SELECTED DRAWING: Figure 3

    【課題】道路標識からの情報をより確実に運転者に対して伝達できるようにする。【解決手段】運転者に対して道路標識に関する注意表示を行うための表示手段11と、前方に存在する道路標識を検出する道路標識検出手段(車外カメラ4)と、運転者の視認方向を検出する検出手段(車内カメラ7)と、制御手段Uと、を有する。制御手段Uは、検出された道路標識の方向と運転者の視認(視線)方向とが相違するときは、運転者が道路標識をみていないとして、検出された道路標識に関する注意情報が表示手段11に表示される一方、上記2つの方向が一致するときは注意表示が行われないようにされる。トンネル内走行時、夜間あるいは降雪時のように道路標識の視認性が悪くなる状況のときは、運転者の視認方向にかかわらず、表示手段11への注意表示が行われる。【選択図】 図3
