Abstract
A vehicular system includes a measuring unit attached to a vehicle to detect a magnetic marker laid along a traveling road, a database storing position information of the magnetic marker, and a control unit that acquires the position information of the magnetic marker by referring to a storage area of the database. The database has stored therein position information of each magnetic marker to which a distance from a reference point on the traveling road as a starting point to each magnetic marker is linked. By referring to the database by using a distance traveled until the magnetic marker is detected after the vehicle passes over the reference point, position information of newly detected magnetic marker is acquired.
Claims20
A vehicular system for acquiring attribute information of magnetic markers laid along a traveling road while a vehicle is traveling, comprising:
- a magnetic sensor attached to the vehicle to detect the magnetic markers;
- a distance identifying part to identify a distance traveled by the vehicle;
- a database having the attribute information of the magnetic marker stored therein;
- and
- an information acquiring part that acquires the attribute information of a magnetic marker detected by the vehicle by referring to the database, wherein
- the database has stored therein the attribute information of each of the magnetic markers to which information that can identify a distance from a reference point on the traveling road as a starting point to the each of the magnetic markers is linked,
- the information acquiring part refers to the database by using the distance identified by the distance identifying part after the vehicle passes over the reference point until the magnetic marker is detected, and
- the information acquiring part acquires, as attribute information of the magnetic marker detected by the vehicle, attribute information to which information that can identify the distance identified by the distance identifying part is linked, in the attribute information of the magnetic markers stored in the database.
