Abstract
The present invention discloses highly accurate driving control of a vehicle using map data. A car information system for controlling a driving control unit group is located in a vehicle. The car information system includes a map database for storing map data, a support area management table in which each kind of attribute data of the map data is associated with information for identifying a field-researched area, and a control unit for estimating an area through which the vehicle travels. The control unit uses a support area management table to judge whether attribute data included in the estimated area is associated with the support area.
