To provide a vehicle navigation system that makes it possible to always set a travel guide route even low in a driving skill, and enables a safe driving.SOLUTION: In a vehicle navigation system including a route setting unit 21 searching for routes to a destination of a vehicle, and setting the retrieved route as a travel guide route, and conducting a travel guide on the basis of the travel guide route, the vehicle navigation system has a search condition setting unit 20 that sets an avoidance request condition in the route to the destination, and the route setting unit 21 is configured to, when the avoidance request condition is not satisfied, and the setting of the route to the destination is disabled, set a route including an avoidance request section not satisfying the avoidance request condition as the travel guide route, and, upon conducting the travel guide on the basis of the travel guide route including the avoidance request section, make a warning to a driver of the vehicle by a speaker 7 or a display part 3 when the vehicle reaches toward the avoidance request section.SELECTED DRAWING: Figure 1

    【課題】運転技量が低くても走行誘導経路を常に設定可能とし、かつ安全な運転を可能にする車両のナビゲーションシステムを提供する。【解決手段】車両の目的地への経路を検索して、走行誘導経路として設定する経路設定部21を備え、当該走行誘導経路に基づいて走行案内をする車両のナビゲーションシステムにおいて、目的地への経路における回避要求条件を設定する検索条件設定部20を有し、経路設定部21は、回避要求条件を満たさずに目的地への経路が設定不能である場合には、回避要求条件を満たさない回避要求区間を含む経路を走行誘導経路として設定し、回避要求区間を含む走行誘導経路に基づいて走行案内をする際に、当該回避要求区間の手前に車両が到達した際に、スピーカー7や表示部3によって車両の運転者に警告をする。【選択図】図1
