Abstract
A map information system includes a database management device configured to manage a map database used for vehicle driving support control. The map database includes background map information that indicates a position of a stationary object and an evaluation value. The evaluation value indicates certainty that the stationary object exists at the position indicated by the background map information. Driving environment information includes: surrounding situation information including information on a detected target detected by an in-vehicle sensor; and vehicle state information indicating the vehicle state. The database management device recognizes relative behavior of the vehicle with respect to the detected target, based on the driving environment information. The database management device determines, based on the relative behavior, whether or not the detected target is the stationary object to set the evaluation value of the background map information regarding a detected position of the detected target.
