  However, the conventional navigation device described above has the following problems. That is, there is a problem that the type of peripheral facility information useful for the user is not selectively displayed on the route to the destination. When the user wants to obtain peripheral facility information, it is necessary to monitor and display all types of peripheral facility information. In this case, the visibility of the road map is significantly reduced, and the desired facility is selected. It becomes difficult to find.

  Therefore, the present invention has been made to solve the above-described problems, and provides a navigation device that can provide facility information useful to the user with high visibility on the way to the destination. With the goal.

  The navigation device according to the present invention includes position information detection means for detecting a current position, situation information detection means for detecting situation information relating to a situation of a car or a passenger, and extraction corresponding to the situation information detected by the situation information detection means. Based on the condition determining means for determining the conditions, the current position detected by the position information detecting means, and the extraction conditions determined by the condition determining means, the extraction conditions of the surrounding facility information are selected from the facility information database. Facility information extracting means for extracting matching facility information, and display means for displaying an icon of facility information extracted by the facility information extracting means on a monitor in a superimposed manner.

  In this navigation device, only the facility information according to the situation of the car or the passenger is selectively provided to the user from the surrounding facility information at the current position including the midway route to the destination. Therefore, useful facility information is provided to the user while ensuring high visibility as compared with the case where all types of peripheral facility information are displayed on the monitor.

  The situation information detection unit may receive an input signal related to the situation information from the user, and the condition determination unit may determine an extraction condition according to the situation information received by the situation information detection unit from the user. In this case, it is possible to provide more useful peripheral information in consideration of the user's request.

  ADVANTAGE OF THE INVENTION According to this invention, the navigation apparatus which can provide the facility information useful to a user with high visibility in the middle route to the destination is provided.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments that are considered to be the best in carrying out the invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected about the same or equivalent element, and the description is abbreviate | omitted when description overlaps.

  A navigation device according to an embodiment of the present invention is, for example, an in-vehicle car navigation device, and uses a position information from a satellite, a gyroscope, or the like to guide an optimal route to a current position of a user vehicle or a destination. Is. FIG. 1 is a block diagram showing a navigation device 10 according to an embodiment of the present invention. The navigation device 10 includes, as functional components, a position information detection unit 12 (position information detection unit), a situation information detection unit 14 (situation information detection unit), an extraction condition determination unit 16 (condition determination unit), and facility information. An extraction unit 18 (facility information extraction unit), a peripheral information display unit 20 (display unit), a monitor 22 and a storage unit 24 are provided. The navigation device 10 is mainly composed of a GPS receiver, a gyroscope, a vehicle position detection device such as a wheel sensor, an arithmetic processing device such as a computer, a storage device such as an HDD, a wireless LAN, etc. as physical components. A display device such as a wireless communication device or a liquid crystal monitor is provided.

  The storage unit 24 stores a facility information database D1 as shown in FIG. 2, an extraction condition determination table D2 as shown in FIG. 3, and a map information database (not shown).

  The facility information database D1 includes the name of the facility (facility name), the address (HP address) of the home page on which the facility information is posted, the information indicating the longitude and latitude of the facility (background information), and the mail in the area where the facility is located. A number (postal code) and a facility telephone number (telephone number) are stored in association with each other. Examples of facilities include “Restaurant A”, “Parking B”, “Gas station C”, “Convenience store D”, etc., even in various stores, public facilities, accommodation facilities, highway service areas, etc. Good. Such a facility information database D1 is generally called a POI search database.

  The extraction condition determination table D2 is a table for determining whether or not each facility stored in the facility information database D1 meets an extraction condition (conditions (a) to (d)) described later. In the table shown in FIG. 3, for example, the extraction condition (a) indicates that “restaurant A” and “parking B” are facilities that meet the condition, and the extraction condition (b) "Parking B" and "Convenience store D" indicate that the conditions are met.

  Returning to FIG. 1, each part of the navigation device 10 will be described.

  The position information detection unit 12 is a part that detects the current position of the user vehicle using a GPS receiver or the like.

  The situation information detection part 14 is a part which detects situation information, and this situation information is information regarding the situation of a car or a passenger. Situation information specifically includes information about the vehicle, such as the type of road on which it is traveling (general roads, expressways, bypasses, etc.), travel lane, travel time, fuel level, number of passengers, (Adults and children, men and women, young people and elderly people, etc.), information on passengers such as continuous boarding time. Such situation information may be either an aspect in which the situation information detection unit 14 automatically detects using various sensors, or an aspect in which the situation information detection unit 14 receives an input signal related to the situation information from the user.

  The extraction condition determination unit 16 is a part that determines the extraction condition according to the situation information detected by the situation information detection unit 14. For example, when the situation information indicating that the continuous boarding time exceeds 2 hours is detected, the condition (condition (a) shown in FIG. 3) that is the extraction condition of the facility having the parking space is changed to the remaining fuel. When the situation information indicating that the remaining amount is small is detected, the condition (condition (c) shown in FIG. 3) that is the extraction condition of the gas station is determined as the extraction condition.

  Based on the current position detected by the position information detection unit 12 and the above extraction condition determined by the extraction condition determination unit 16, the facility information extraction unit 18 selects from the facility information database D1 out of the peripheral facility information. The facility information that matches the above extraction conditions is extracted. Specifically, the facility that matches the extraction condition (for example, the condition (a)) determined with reference to the extraction condition determination table D2 is extracted, and only the surrounding facilities are extracted from the extracted facilities. Are selected from the facility information database D1 using the “background position information” and “zip code” as a key, and the facility information relating to the facility is extracted.

  The peripheral information display unit 20 is a part that displays the facility information icon extracted by the facility information extraction unit 18 on the monitor 22 so as to overlap the peripheral map. For example, as shown in FIG. 4, only icons of the extracted facility information (restaurant A, parking B) are displayed on the monitor 22 so as to overlap the surrounding map.

In the navigation device 10 described above, the following modes can be realized.
(1) When the continuous boarding time exceeds 2 hours, the facility information of the facility having the parking space is selectively displayed on the monitor.
(2) When the remaining amount of fuel divides a predetermined threshold, the facility information of the gas station is selectively displayed on the monitor.
(3) When the meal time comes, restaurant facility information suitable for the boarding combination and the number of passengers is selectively displayed on the monitor.
(4) On a road with a median strip, the facility information of the facility on the left in the traveling direction is selectively displayed on the monitor.
(5) While traveling on an expressway, the facility information of the service area / parking area is selectively displayed on the monitor (without displaying the facility information of the facilities along the surrounding general road).

  Thus, in the navigation apparatus 10, not only at the destination but also at the current position including the midway route to the destination, only the facility information corresponding to the situation of the car or the passenger is selected from the surrounding facility information. Is selectively provided to the user.

  Therefore, according to the navigation apparatus 10, when the peripheral facility information of all types is displayed on the monitor ("restaurant A", "parking B", "gas station C", "convenience store D" as shown in FIG. 5). Compared to the case where the information is displayed), facility information useful to the user is provided while ensuring high visibility.

  The situation information detection unit 14 receives an input signal related to the situation information from the user, and the extraction condition determination unit 16 determines the extraction condition according to the situation information received by the situation information detection unit 14 from the user. It is possible to provide more useful peripheral information in consideration of the user's request.

  The present invention is not limited to the above embodiment, and various modifications are possible. For example, the facility information database D1 does not necessarily have to be stored in the storage unit 24 of the navigation device 10, and as shown in FIG. 6, a server 30 (facility information storage) that can communicate with the navigation device 10 via the network NW.
