PROBLEM TO BE SOLVED: To provide a car navigation system which is capable of determining a destination complying with a vehicle travel pattern of a user on the basis of probe information collected from a vehicle and performing route search.SOLUTION: A car navigation system comprises a car navigation device 2 and a route search device 1. The car navigation device 2 intermittently transmits information about a position of a vehicle C and a time. The route search device 1 comprises: an information accumulation part which receives and accumulates the information transmitted from the car navigation device 2; a destination determination part which determines a destination on the basis of the received information about the current position of the vehicle and time and the information accumulated by the information accumulation part; and a route search part which searches for a route leading to the destination determined by the destination determination part. The route search device 1 transmits route information acquired by searching to the car navigation device 2. The car navigation device 2 receives the route information and guides the vehicle C to the destination on the basis of the received route information.

    【課題】車両から収集されるプローブ情報に基づいて、ユーザの車両走行パターンに沿った目的地を特定し、経路探索を行うことができるカーナビゲーションシステムを提供する。【解決手段】カーナビゲーションシステムは、カーナビゲーション装置2と、経路探索装置1とを備える。カーナビゲーション装置2は、車両Cの位置及び時刻の情報を間欠的に送信する。経路探索装置1は、カーナビゲーション装置2から送信された情報を受信し、蓄積する情報蓄積部と、受信した現在の車両の位置及び時刻の情報、及び前記情報蓄積部が蓄積した情報に基づいて、目的地を特定する目的地特定部と、該目的地特定部が特定した目的地へ至る経路を探索する経路探索部とを備える。経路探索装置1は、探索して得た経路情報を前記カーナビゲーション装置2へ送信する。カーナビゲーション装置2は、経路情報を受信し、受信した経路情報に基づいて車両Cを目的地へ案内する。【選択図】図1
