Title: Route guiding apparatus
Inventor: TSUDA SHINGO
IPC: G08G1/0969
Filed: 1993-03-04
Abstract: PURPOSE:To impart a sense of security to a driver by deciding whether any of candidate roads registered by travel route specifying means includes a calculated optimum road or not, and informing the gist to the driver if any one includes to optimum road and does not include at all. CONSTITUTION:An MIC(multiple information controller) 1c first confirms that an optimum route is obtained, and confirms a number of a registered link from a locater 1b. Then, it refers to similarity of the link, and compares the number of the link of a predetermined value or more of the similarity with a number of the link included in the optimum route. If there is the link of the same number, it confirms whether a travel route flag is '1' or '0'. The flag '1' indicates that a vehicle is on the optimum route and '0' indicates that the vehicle is out of the optimum route. Accordingly, if the flag is '0', it displays a driver that the vehicle falls within the route. If the flag is '1', the driver may advance as it is. If there is no link of the same number, the driver confirms the flag. If the flag is '1', it displays the driver that the vehicle is deviated from the route. If the flag is '0', the driver may advance as it is. The process is returned to an initial, and repeated.
