Toyota Motor Corp on Thursday announced that it has developed the world's first technology for automatically delivering differential map data to car navigation systems. The technology, named "Map on Demand," will be made available to drivers as a new feature of Toyota's G-BOOK telematics service from spring, the company said in a statement.
Map on Demand, which was jointly developed with Aisin AW Co, Ltd, Zenrin Co, Denso Corporation and Toyota Mapmaster Incorporated, delivers updated data on all Japanese expressways and toll roads, as well as on roads near the registered home of the subscriber and on roads in the vicinity of user-specified destinations. Data is delivered via cell phone networks, Internet downloads, etc.
Although conventional data updating and editing for car navigation maps is conducted on a nationwide basis — involving a large volume of data and requiring considerable data transfer time and cost — Map on Demand focuses only on updates for areas specified by users, in addition to data for expressways and toll roads, Toyota said.
In cases in which a modified road extends beyond the area specified by users for updating, the update area is extended to include connection to another road. This allows the car navigation system to provide route-connection information, with such connection information covering all roads throughout Japan.
