PROBLEM TO BE SOLVED: To provide a navigation device and a route setting method that can set a route down to a destination in accordance with a level of travelling difficulty closer to reality.SOLUTION: A navigation device comprises: a travelling difficulty level judgement unit 102 that judges a travelling difficulty level of roads on the basis of rainfall information, and any one of gradient information and geological information; and a route setting unit 103 that sets routes down to a destination on the basis of the travelling difficulty level judged by the travelling difficulty level judgement unit 102. Accordingly, the travelling difficulty level to be judged is configured to be appropriate in consideration for an actual rainfall state, a gradient level of a road surface and geology of the road surface which greatly affect an actual road surface state, and the route down to the destination is set based on the appropriate travelling difficulty level in accordance with the actual road surface state.SELECTED DRAWING: Figure 1
【課題】より現実に近い走行難易度に応じて、目的地に至る経路を設定することが可能な「ナビゲーション装置および経路設定方法」を提供する。【解決手段】降雨情報と、傾斜情報および地質情報の少なくともいずれか一つとに基づいて、道路の走行難易度を判定する走行難易度判定部102と、走行難易度判定部102によって判定された走行難易度に基づいて、目的地に至る経路を設定する経路設定部103とを備えることにより、判定される走行難易度が、実際の路面状況に大きな影響を及ぼす、実際の降雨状況と、路面の傾斜度と、路面の地質とが考慮された適切なものとなるようにし、このように実際の路面状況に応じた適切な走行難易度に基づいて、目的地に至る経路が設定されるようにする。【選択図】図1
