摘要： A communication navigation system, wherein a navigation apparatus requests a recommended route guidance data to a information center and guides a user of the navigation apparatus to a destination by using the recommended route guidance data received from the information center. In this present invention, the navigation apparatus transmits version data of road data held in the navigation apparatus at the request to the information center. The information center prepares a guidance data of recommended route using latest road data held in the information center, and transmits the data to the navigation apparatus. When the information center transmits the guidance data, the information center selects the type of data of the road links along the recommended route, in the guidance data, by comparing the version data received from the navigation apparatus and the version data of each road link along the recommended route. If each data of road links along the recommended route is considered to be contained in the road data held in the navigation apparatus, the information center transmits the only data which enable to specify the road link from the road data held in the navigation apparatus. On the hand, if each data of road links is considered not to be contained in the road data held in the navigation apparatus, the information center transmits whole data of the road link. Therefore, the navigation apparatus can generate the route guidance data by extracting road link data, from its own road data, corresponding to the road link specified by transmitted data and by reconstructing road link data using transmitted data.

摘要： Disclosed is a communicatory navigation system including an information center (150), at least one navigation unit (100) each mounted on a vehicle and communication means for allowing bi-directional data communication between the information center and the navigation unit. Data transmission from the navigation unit to the information center is made during a period of communication that begins when the navigation unit become communicable with the information center and ends when the bi-directional data communication therebetween is disconnected. The navigation unit is provided with a drive route history memory area (131) and an instrument operation history memory area (132), and data in these memory areas are transmitted to the information center, together with the vehicle current position data and the destination position data. The information center determines a recommended drive route from the current position to the destination, not only with reference to its own database (158) but also taking into consideration the history data. For example, if it is determined that there is a traffic accident or heavy traffic jam in some route, a bypass route is determined and transmitted back to the navigation unit. When the previous drive route indicated by data in area (131) is not found in the database (158), it can be recognized as a newly constructed road for inclusion in the database.

摘要： A navigation system includes a navigation center and a plurality of navigation apparatuses each of which has a data storage that stores various information. In this navigation system, data (coordinate data of each of traveling intersections) concerning a recommended route is transmitted from the navigation center to the navigation apparatus, and then route guidance is carried out in the navigation apparatus using the data received from the navigation center. In the case where the navigation apparatus has intersection data for an intersection specified by the data received from the navigation center, the navigation apparatus extracts the intersection data for the intersection from the data storage. Further, in the case where the navigation center does not have intersection data for an intersection specified by the data received from the navigation center, the navigation apparatus establishes the intersection as a newly-built intersection on the recommended route. Then, the navigation apparatus produces route guidance data (which is used for providing route guidance to a user) using the extracted intersection data, and/or intersection data concerning the established newly-built intersection in addition to the information in the data storage.

摘要： A communication route guidance system provides exchange of data between an information center and each of a plurality of mobile units such as vehicles. The information center has the latest road data and searches it to prepare recommended route guidance data in response to a request from the mobile unit. The reccommended route guidance data is divided into a plurality of data segments, each usable as an independent guidance instruction in the mobile unit. The mobile unit has stored therein road data similar to the road data in the information center and determines if data communication with the information center is available. In a case where the mobile unit can not communicate with the information center, the mobile unit prepares route guidance based on the road data stored in the mobile unit. It thereby becomes possible to guide the user even in the case that the mobile unit can not communicate with the information center. Even in a case where a communication link is disrupted during transmission of route guidance data to the mobile unit, the mobile unit can effectively prepare whole route guidance data in combination with already-received route guidance data and additionally prepared route guidance data by reference to the road data stored in the mobile unit because the already received route guidance data is structured to be usable independently.

摘要： In a communications navigation system, data is transmitted and received between a navigation base apparatus provided at a navigation base and each of a plurality of navigation apparatuses provided in moving bodies such as vehicles using communication. A determining section of the navigation base apparatus determines untraveled route portion by comparing user's information stored in a user information storage with information of a recommended route provided by a route search section. The navigation base apparatus extracts necessary route/guidance information for untraveled route portion determined by the determining section from route/guidance data stored in a database, and then transmits the extracted route/guidance data to the navigation apparatus identified by the identification information. The route/guidance information may be transmitted to the navigation apparatus in the form of segmented data. In this way, it becomes possible for the navigation apparatus to extract only the route/guidance information needed by the user from the route/guidance data stored in the database.

摘要： In this navigation apparatus, when speech recognition of inputted speech is carried out, keywords included in the content of the recognized speech are searched from a dictionary DB, and then these words are displayed as keywords of a POI search. When a correction of a keyword is required by the user, because most errors occur in the first phonetic symbol of the misrecognized word, a search of words each having phonetic symbols in which the first phonetic symbol of the misrecognized word is changed from the phonetic symbols of the word to be corrected (i.e., a search of words having one different first phonetic symbol) is carried out to present candidates for correction. In this navigation apparatus, because the displayed candidates for correction are limited to words having a different first phonetic symbol which has a high possibility of being the cause of misrecognition, the user can correct the misrecognized keyword by a simple operation. Further, it is possible to reduce the process burden as compared to the conventional misrecognition correction processes.
