To provide a drowsiness sign notification system which warns a driver of a drowsiness sign while suppressing discomfort that an occupant feels.SOLUTION: A drowsiness sign notification system includes a driver monitor that detects a driver state, which is a state of a driver of a vehicle. The drowsiness sign notification system determines whether the driver is showing signs of drowsiness on the basis of the driver state. When a determination is made that the driver is showing signs of drowsiness, the drowsiness sign notification system executes first drowsiness sign notification processing which issues a first drowsiness sign notification FB1 by display or vibration without using sound. After the first drowsiness sign notification processing, a determination is made that the driver is still showing signs of drowsiness, the drowsiness sign notification system executes second drowsiness sign notification processing which issues a second drowsiness sign notification FB2 to the driver by sound.SELECTED DRAWING: Figure 2

    【課題】同乗者が感じる煩わしさを抑制しながら、ドライバに眠気兆候があることを通知する眠気兆候通知システムを提供する。【解決手段】眠気兆候通知システムは、車両のドライバの状態であるドライバ状態を検出するドライバモニタを備える。眠気兆候通知システムは、ドライバ状態に基づいて、ドライバに眠気兆候があるか否かを判定する。ドライバに眠気兆候があると判定された場合、眠気兆候通知システムは、音声を用いることなく表示又は振動を通してドライバに第1眠気兆候通知FB1を出す第1眠気兆候通知処理を実行する。第1眠気兆候通知処理の後、ドライバに眠気兆候があると再度判定された場合、眠気兆候通知システムは、音声を通してドライバに第2眠気兆候通知FB2を出す第2眠気兆候通知処理を実行する。【選択図】図2
