Car Information System, Map Server And On-Board System

摘要

According to the present invention, the highly accurate control can be realized in a system for performing the driving control of a vehicle using map data. A car information system 10 for controlling a driving control unit group 50 is located in a vehicle so that the driving control of the vehicle is performed. The car information system includes, a map DB 100 for storing map data, a support area management table 110 in which each kind of attribute data of the map data is associated with information for identifying a field-researched area (support area), and a control unit 200 for estimating an area through which the vehicle travels. The control unit uses a support area management table 110 to judge whether or not attribute data included in the estimated area is associated with the support area. If it is judged that the attribute data is associated with the support area, the control unit performs the driving control of the vehicle by use of the map data, whereas if it is judged that the attribute data is not associated with the support area, not performing the driving control of the vehicle by use of the map data.
