Description

  The present invention relates to a vehicle regulation information providing device and a regulation information providing system for providing regulation information on familiar road construction and the like to a user.

  Conventionally, when road construction is performed, for example, a construction contractor installs a signboard on which a construction name, scheduled construction date and time, and regulation information such as construction contents are placed on the road. In this case, the vehicle occupant confirms the sign when the vehicle passes the road on which the sign is installed. However, in this case, the regulation information on the signboard may not be sufficiently confirmed by visual observation from the vehicle.

Note that VICS (Road Traffic Information Communication System) is known as a means for providing regulation information due to construction or the like. This VICS provides information such as traffic jams, accidents, traffic regulations, etc. to the VICS Center from prefectural police road managers and other information sources, and the VICS Center transmits the information to the vehicle (FM multiplexing) Broadcasting and radio wave beacons).

Therefore, the restriction information described on the signboard is notified to the display device, the sound generator, and the like. It is possible to know by means of this, so that unlike the case of visual confirmation, it is possible to know the regulatory information with certainty, which is convenient. Furthermore, since this restriction information is stored in the storage means and notified at a predetermined timing, it can be confirmed again. Such a regulation information system is very convenient because it can know the regulation information when, for example, a local road is used for daily commuting or living. Moreover, since the information is directly received from the information transmission apparatus without going through the VICS center or the like, the system configuration is also simple.

In the vehicle regulation information providing device according to claim 2, since the vehicle is notified of the regulation information at a timing passing through the regulation place indicated by the regulation information or the vicinity thereof, the regulation information can be known at a necessary point. It is very convenient.
