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 searching, in order to reduce the number up to the candidate further second inputs similarly third Romaji (in this case inputs the U since it is F U KUOKA). 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 highway exit 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 determination section 9 always compares the user's current position 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 for measuring the current position, a position information storage unit for storing information on expressways nationwide, and an information storage for storing position information requiring notification. Unit, a branch information processing unit for examining a highway junction, a notification determination unit for comparing information of the own position with the information in the information storage unit, and a warning transmission device, so that a notification is made when approaching a set position. be able to. As is apparent from the above embodiments, according to the present invention, the current position of the user is measured by the own position measuring device.
By setting the exit where the user gets off the highway before using the highway and the service area where the vehicle stops, the service area where the user stops while driving on the highway, the branch point to pass through, and the exit of the highway are approaching. It is possible to provide a position notification device that can be known in advance by a warning sound.
