发明名称 Travel History Collection System And Terminal Side Device Used For It
摘要 A travel history collection system includes a terminal side device and a center side device capable of communicating with the terminal device. The terminal device includes the following components. A vehicle information acquisition part acquires a travel history of a vehicle. A short-range wireless communication means and a wide-range wireless communication means are used to transmit the acquired travel history to a center device. A travel history transmission part transmits the travel history to the center device via the short-range wireless communication means when the travel history can be transmitted via the short-range wireless communication means, and via the wide-range wireless communication means when the travel history cannot be transmitted via the short-range wireless communication means. The center device receives the travel history from the terminal device via the wide-range wireless communication antenna and the road side unit so as to reduce the load on wide-range wireless communication, and to accurately collect a travel history from each terminal device at real time. Thus, latest travel histories can be collected efficiently.
