DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a position notification device according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a self-position measuring device capable of measuring a current position, and 2 denotes a name of a highway entrance / exit nationwide, a service area name and a highway entrance / exit position, a highway branch point position, and a service area position. A high-speed approach determination unit that determines whether or not the user has approached the highway entrance based on the positioning result of the own position measurement device, and a highway exit that gets off the highway. And a notification position input unit for inputting information of a service area that stops while driving on a highway, 5 is a display unit that displays the names of entrances and exits of highways nationwide, and a service area name. From the determined expressway entrance,
A branch information processing unit for checking the position of a highway branch point passing to the highway exit input by the notification position input unit 4, and a branch information processing unit for checking the name and position of the service area existing from the set highway entrance to the exit. Service Area Information Department,
Reference numeral 8 denotes an information storage unit that stores the position of a highway junction where the user passes when driving on the highway, the stop service area input by the notification position input unit 4, and the position information of the highway exit. A notification determination unit that compares the positioning result of the device 1 with the position information stored in the information storage unit 8 to determine whether the user is approaching a highway junction, a stopped service area, or an expressway exit, and a warning 10. Is a control unit for controlling the entire apparatus.

Next, the mutual relationship and operation of the above components of the position notification device of the present embodiment will be described with reference to FIGS.

The present apparatus always measures the current position of the user by using its own position measuring device 1 (for example, a GPS device).
Based on the positioning result, the expressway approach determination unit 3 determines whether the user is within a preset range (for example, 500 m) from the entrance of the expressway.
When the expressway approach determination section 3 determines that the vehicle is within the preset range, the position information of the entrance of the expressway determined to be approached is stored in the information storage section 8, and the vehicle stops while traveling on the expressway. It is required to input position information of a service area and an exit from an expressway.

When a user uses an expressway, an exit to get off the expressway and a service area to be stopped while driving on the expressway are registered in the following order using the notification position input unit 4.

This registration is performed by inputting the names of the expressway exit and the service area in Roman characters in units of one character. For example, in the case of Fukuoka, F is input.

In this character input method, first, as shown in FIG. 3, a group selection key is pressed several times, and a character group (1.ABCDEFG, 2.HIJKL) to which a character to be input belongs belongs.
M, 3. NOPQRS, 4. TUVWXYZ). This group is displayed on the display unit 5. Thereafter, the under bar displayed below the character is moved to below the character to be searched (F in this case) using the under bar moving key. After moving the underbar to the position of F, the enter key is pressed, and this character is registered as a search target character. After the search, in order to reduce the number of candidates, the second and third Roman characters are similarly input (in this case, U is input because it is FUKUOKA). After inputting the characters to be searched, press the search key to perform the next search.

When a search key is input, a search is performed based on the information stored in the position information storage unit 2 (however, the first search is directed to the expressway exit, and the second and subsequent searches are performed). This is performed for service areas that exist from the expressway entrance to the registered expressway exit.) When the search is completed, the expressway exits that have become candidates are displayed on the display unit 5 in Japanese. The user presses a scroll key to search for an expressway exit to register as shown in FIG. When the expressway exit to be registered is displayed, the enter key is pressed, and the position information is stored in the information storage unit 8.

When the expressway exit is determined as described above,
Based on the information in the information storage unit 8, the service area information processing unit 7 checks the service area existing from the entrance to the exit of the expressway.

Further, the user inputs, searches, selects, and registers the service area position in Roman letters in the same manner as described above to register the service area to be stopped. If there is another service area to stop, registration is performed by the same operation. When the registration is completed, press the registration end key.

When the user merely approaches the entrance of the expressway and does not use the expressway, or does not use the present apparatus, the position information is not input even if a position information input request is issued. This position information input request is canceled when the expressway approach determination unit 3 determines that the user has moved out of the preset range from the entrance of the expressway.

When the registration of the notification position is completed, the branch information processing unit 6 checks a highway junction that passes from the entrance of the highway to the exit of the highway set by the notification position input unit 4.
The position information is stored in the information storage unit 8.

When the above processing is completed, the notification determining section 9 always compares the current position of the user determined by the positioning of the own position measuring device 1 with the notification position stored in the information storage section 8 and presets it. Range (for example, 500
It is determined whether the user has moved to m). When it is determined that the user has approached the notification position, the warning transmission device 1
Use 0 to warn the user. When the user leaves the highway exit, the device returns to the initial standby state.

As described above, according to the present embodiment, a self-position measuring device that measures the current position, a position information storage unit that stores information on expressways nationwide, and information that stores position information that needs to be notified. Since it has a storage unit, a branch information processing unit for examining a highway junction, a notification determination unit for comparing the information of the own position and the information storage unit, and a warning transmission device,
It can notify when approaching the set position.

[0022]

As is apparent from the above embodiment, according to the present invention, the current position of the user is measured by the self-position measuring device, and the user exits the expressway before using the expressway.
A position notifying device that allows a user to know in advance a service area to be stopped while driving on a highway, a branching point to be passed, and an approach to an expressway exit by a warning sound by a configuration in which a service area to be stopped is set in advance. Can be provided.
