PROBLEM TO BE SOLVED: To provide a remaining amount alarm system that can perform alarm at an appropriate timing without making a user feel annoyed in a living area or making him/her worry about fuel shortage in a non-living area, and a navigation device to which the remaining amount alarm system is applied.SOLUTION: A remaining amount alarm system comprises: remaining amount recognition means (40) for recognizing a remaining amount of an energy source of a vehicle; location identification means (30) for identifying a current location of the vehicle; first alarm means where different alarm levels of the remaining amount are set for at least two areas (S46) for performing alarm when the remaining amount is the alarm level for the area corresponding to the current location (S86); and second alarm means where at least a caution level at which the remaining amount is larger than at the alarm level is set for an area where the lowest alarm level is set (S46) for performing a weaker alarm than that the first alarm means performs when the remaining amount is the caution level for the area corresponding to the current location (S74).
【課題】生活圏ではうっとうしさを感じさせず、非生活圏では燃料が切れる不安を抱かせないよう適切なタイミングで警報を行うことができる残量警報システム、及びこれが適用されたナビゲーション装置を提供する。【解決手段】残量警報システムは、車両のエネルギー源の残量を認識する残量認識手段(40)と、車両の現在位置を特定する位置特定手段(30)と、少なくとも2つの地域に異なる前記残量の警報レベルが設定され(S46)、前記残量が前記現在位置に対応する前記地域の前記警報レベルである場合に警報を行う第1警報手段と(S86)、最も低い前記警報レベルが設定された地域に前記警報レベルよりも前記残量が多い注意レベルが少なくとも設定され(S46)、前記残量が前記現在位置に対応する前記地域の前記注意レベルである場合に、前記第1警報手段が行う警報よりも弱い警報を行う第2警報手段(S74)と、を備える。【選択図】図4
