摘要:
The invention relates to a navigation method and a navigation system (100) for motor vehicles, for navigating from a present location to a destination. In response to an emergency user request, the nearest emergency destination to the present location is determined from a database, defined as the destination and a route is calculated from the present location to the emergency destination. The navigation system (100) comprises a memory (22) with a database for emergency destinations and a device (26) for determining the nearest emergency destination to the present location from the database.

A navigation guidance system is provided which gives direction information to a user via their mobile telephone. In one embodiment, the user pre-arranges their trip using a web-based route calculation server. The web-based server prompts the user to provide their mobile telephone number so that updated navigation instructions can be provided to the user as they are travelling towards their destination. In a preferred embodiment, the mobile telephone number and the user's travel plans are transmitted to a second navigation server which transmits a text message to the user's mobile telephone prompting them to call a given number to receive updated navigation instructions to arrive at their chosen destination.

A navigation apparatus (15) includes a memory (16) that stores registered routes, wherein each registered route includes a previously traveled route, a corresponding starting point, and a corresponding destination point. The navigation apparatus includes a controller (17) that searches for a route from a specified starting point to a specified destination point, compares the searched route with the registered routes, and utilizes, if a corresponding starting point is substantially identical to the specified starting point or a corresponding destination point is substantially identical to the specified destination point, a portion of a registered route including the substantially identical starting point or the substantially identical destination point as a navigation route.

A communication navigation system is provided with a communication center apparatus (3) and a communication terminal apparatus (4, 5), both of which transmit and receive information by two-way communication through a communication network (1, 2). The communication center apparatus is provided with: a processing device (72) for generating request correspondence information including route information indicating a planned route corresponding to request information and generating, if at least one portion of the planned route is present out of a service area of the communication navigation system, announcement information for announcing this fact; and a center side communication device (71, 73) for receiving the request information and transmitting the request correspondence information and the announcement information through the communication network. The communication terminal apparatus is provided with: a terminal side communication device (38) for transmitting the request information and receiving at least the announcement information through the communication network; and an input device for inputting the request information and giving an opportunity of inputting the request information in response to the reception of the announcement information.

A travel information distribution system includes a distribution center and a wireless terminal of a user who can readily obtaining necessary travel information in traveling places using the wireless terminal such a portable telephone or a portable personal computer. The user visits a travel agency to apply a travel, has a travel schedule table prepared and registers a telephone number of the wireless terminal in a database. The travel agency sends the data of the user to the distribution center, and distribution center receives travel information from information providers. After the departure of the travel, the distribution center transmits necessary travel information to the user at a proper time in a proper place. The user can obtain the necessary updated information in the necessary place and can be free from a heavy weight travel guidebooks. The distribution center can obtain advertisement incomes from travel agencies and advertisement firms.
摘要:
A system (UTMS) is disclosed for sending guiding destination data to a control center and calculating a recommended route at the control center while taking traffic conditions into account and presenting the route to a vehicle, in which a route guidance apparatus promptly obtains the recommended route. A controller installed on the vehicle uses data stored in a map data memory to independently search for a route to a destination, and a UTMS link positioned on the obtained route is transmitted to the control center as guiding destination data. Until the search completes, immediately after the destination has been set, a UTMS area to which that destination belongs is transmitted to the control center as temporary guiding destination data. Thereafter, a UTMS link that appears from the search is transmitted as guiding destination data. A recommended route is obtained from the control center even before the search completes, thereby improving the utilization efficiency of the UTMS.
