PROBLEM TO BE SOLVED: To perform automatic lighting of a hazard lamp at an appropriate timing according to a travelling circumstance.SOLUTION: A controller 21 performs, when deceleration α of a vehicle 1 is a prescribed threshold value or more, automatic lighting of a hazard lamp 2. The prescribed threshold value is varied according to a travelling circumstance. For example, the prescribed threshold value is changed, when visibility is worsened in a travelling circumstance such as during the night, to be a smaller value in comparison with the daytime on the basis of detection by an illuminance sensor or a headlight switch. The prescribed threshold value is changed, when brake performance is worsened in the travelling circumstance such as rainy weather, to be smaller value in comparison with travelling on the dry road on the basis of detection by the illuminance sensor or the headlight switch.

    【課題】走行環境に応じて、ハザードランプを適切なタイミングで自動点灯させる。【解決手段】コントローラ21の制御によって、車両1の減速度αが所定のしきい値以上となったときに、ハザードランプ2が自動点灯される。走行環境に応じて、所定のしきい値が変更される。例えば、所定のしきい値は、夜間のように視認性が悪化する走行環境のとき(例えば照度センサやヘッドライトスイッチにより検出)には、昼間に比して小さい値に変更される。また、所定のしきい値は、例えば雨天時のように制動性能が悪化する走行環境のとき(例えば照度センサやヘッドライトスイッチにより検出)には、乾燥路を走行する場合に比して小さい値に変更される。【選択図】 図3
