To combine safety and convenience by mitigating operation restrictions on a specific function when predetermined conditions are satisfied while issuing a warning when operation of portable equipment by a driver is detected while a vehicle is traveling.SOLUTION: A vehicle warning device issues a warning to a driver according to a state of the driver and a use state of a portable equipment while a vehicle is traveling, and includes a warning level determination unit and a warning unit. The warning level determination unit acquires line-of-sight information including a direction of a line-of-sight of the driver, motion information indicating motion of a specific portion of the driver, and screen information indicating a state of a screen of the portable equipment, determines a state of the driver and a use state of the portable equipment by the driver based on the information, and determines a warning level relative to the driver according to determination results. The warning unit gives stronger warning at a higher warning level according to the warning level. The warning level determination unit lowers the warning level when a function in use in the portable equipment is a permitted function permitted in advance.SELECTED DRAWING: Figure 1
【課題】車両走行中に運転者による携帯機器の操作を検知した場合に警告を行いながら、所定の条件を満たす場合には特定の機能についての操作制限を緩和し、安全性と利便性を両立させる。【解決手段】車両の走行中に、運転者の状態及び携帯機器の使用状態に応じて運転者に警告を発する車両用警告装置であり、運転者の視線の方向を含む視線情報と、運転者の特定部位の動きを示す動き情報と、携帯機器の画面の状態を示す画面情報とを取得し、これらに基づいて、運転者の状態と運転者による携帯機器の使用状態を判定し、判定結果に応じて運転者に対する警告レベルを決定する警告レベル判定部と、警告レベルに応じて、警告レベルが高いほど強い警告を行う警告部と、を備え、警告レベル判定部は、携帯機器における使用中の機能が予め使用が許可された許可機能である場合に警告レベルを低下させる、車両用警告装置を提供する。【選択図】図1
