JP5197538B2 - Navigation device - Google Patents

Description

  The present invention relates to a navigation apparatus for guiding an optimum route from a departure place to a destination, and more particularly to a technique for automatically setting a registration place.

  Conventionally, an automatic point storage device applied to, for example, a navigation device is known. For example, Patent Document 1 discloses an automatic point storage device that can perform point registration without a user's own operation. This automatic location storage device stores position data acquired by GPS (Global Positioning System) at that time based on a predetermined condition when an ignition switch of a vehicle is turned on. Further, the memory count corresponding to the position data stored at the point indicated by the position data is incremented by one, and at the same time, the current day of the week and date / time data are also stored corresponding to the position data. Thereafter, the stored position data and the corresponding memory count, day of the week, and date / time data are called up as necessary, and the parking spot on the way of movement is known from the called up position data. Further, using the additional information of the data of the memory count, day of the week, and date / time, the position data is searched, grouped, or sorted.

JP-A-2005-321407

  However, in the technique disclosed in Patent Document 1 described above, the number of memory points increases because the number of memory points increases when the ignition switch is turned on. Moreover, although it has a sorting function based on day of the week and date and time data, it does not always go to the same point every time, so the more memory points, the more complicated the operation. Also, a location that has never been visited cannot be registered as a memory location.

  By the way, since the above-mentioned conventional navigation apparatus has many state transitions according to operation, the person unfamiliar with operation of a device has hesitation in using a navigation apparatus, and, in an extreme case, there is also a person who does not use a navigation apparatus. In addition, the navigation device is convenient when used in an unfamiliar place or travel, but actually, it is often used for shopping around the home, pick-up, commuting or school.

  When using a navigation device, the destination is set first, and then the user is guided to the destination safely and reliably by the search function and the guidance function. The device is difficult to use. There are several methods for setting the destination, such as setting from a map, setting from a telephone number, or setting from an address. Since the accuracy of the position is also good, a method of setting a destination from a registered place is used by many users.

  However, since a lot of operations are required to set a plurality of registered locations, beginners tend to refrain from doing so. For example, a simple setting method such as automatic setting of registered locations is desirable. By adopting such a simple operation method, it is desired that a person unfamiliar with the navigation apparatus can experience the convenience of the navigation apparatus and wipe out allergies of the navigation operation.

  The present invention has been made to meet the above-described demand, and an object thereof is to provide a navigation device that is easy to operate so that the convenience of the navigation function can be experienced.

The present invention, in order to solve the above problems, a position detector for detecting a current position, a map data storage unit for storing map data, when the first home set is performed, detected by the position detection unit a control unit for automatically searching based facilities that exist from home position to within a few kilometers area in the map data read from the map data storage unit, automatically displaying separately by facility search control section for each genre A display unit, an operation input unit that selects a facility displayed on the display unit, and a registration site storage unit that automatically stores the facility selected by the operation input unit as a registration site are provided.

  According to this invention, when the home setting is performed for the first time, the facility existing within the predetermined range from the home position is searched and displayed for each genre, and the facility selected from the displayed is set as the registration place. Since it is configured to register, it is possible to easily set the destination from the registered place when going to the facility around the home. As a result, even if you are not familiar with the operation of equipment when you go to facilities around your home, you can easily set the destination, so you can experience the convenience of navigation devices and allergies to navigation operations. Can be wiped off.

Embodiment 1 FIG.
1 is a block diagram showing a configuration of a navigation apparatus according to Embodiment 1 of the present invention. The navigation device includes a GPS system 11, a position detection unit 12, an operation input unit 13, a ROM (Read Only Memory) 14, a RAM (Random Access Memory) 15, a map data storage unit 16, a control unit 17, and a display unit 18. ing.

  The GPS system 11 receives data for specifying the current position transmitted from a GPS satellite, and sends the data to the position detection unit 12 and the control unit 17. The position detector 12 detects the current position based on the data sent from the GPS system 11 and sends it to the controller 17 as current position data.

  The operation input unit 13 includes, for example, a touch panel or an operation switch, and is used to input various data to the navigation device. Data input from the operation input unit 13 is sent to the control unit 17 as operation data.

  The ROM 14 is composed of an EEPROM (Electrically Erasable Programmable ROM) and corresponds to the “registered location storage unit” of the present invention. The ROM 14 stores program data necessary for calculation, a registration location, and the like, and is accessed by the control unit 17. The RAM 15 temporarily stores data during the calculation. The RAM 15 is accessed by the control unit 17.

  The map data storage unit 16 stores map data. The map data stored in the map data storage unit 16 is read out by the control unit 17. The control unit 17 controls the entire navigation device by executing predetermined processing using the GPS system 11, the position detection unit 12, the operation input unit 13, the ROM 14, the RAM 15, and the map data storage unit 16. Details of processing executed by the control unit 17 will be described later. The display unit 18 displays a map or data for setting a destination according to the display data sent from the control unit 17.

  Next, the operation of the navigation device according to Embodiment 1 of the present invention configured as described above will be described. First, processing from home registration to registration place setting completion, that is, registration place setting processing around the home will be described with reference to the flowchart shown in FIG.

  When the navigation device is attached to the vehicle, a registered location setting process around the home is started. In this registered location setting process around the home, first, the home is set (step ST11). That is, the control unit 17 stores the operation data sent from the operation input unit 13 in the ROM 14 as data indicating the home. When this home setting is completed, a screen representing the completion of home registration as shown in FIG. Since the user has a sense of geography around his home, the user can operate the home setting even for a beginner. If home setting is difficult for the user, it can be set at the store at the time of purchase.

  Next, it is checked whether or not this is the first home registration (step ST12). That is, the control unit 17 checks whether the home setting is performed for the first time or whether re-registration is performed by moving or the like. If it is determined in step ST12 that this is the first home registration, the sequence proceeds to step ST13.

  On the other hand, if it is determined in step ST12 that it is not the first home registration, it is checked whether or not to delete the previous registration area around the home (step ST18). By the selection in this step ST18, the user can specify whether or not to delete the previous registration area around the home when the home registration is re-registration. If it is determined in step ST18 that the previous registered locations around the home are to be deleted, the previous registered locations around the home are deleted (step ST19). Thereafter, the sequence proceeds to step ST13. On the other hand, if it is determined in step ST18 that the previous registered locations around the home will not be deleted, the registered locations around the previous home are stored in the list (step ST20). Thereafter, the sequence proceeds to step ST13.

  In step ST13, a home surrounding facility search is performed. More specifically, when home is set, the control unit 17 refers to the map data stored in the map data storage unit 16, that is, the point indicated by the current position data sent from the position detection unit 12, that is, Search for a facility within a predetermined range, for example within a few kilometers from home. Then, the found facilities are classified by genre (for example, shopping, hospital, car, meal, station, school, etc.).

  Next, the search results are displayed by genre (step ST14). That is, the control unit 17 sends display data representing the genre of the facility searched in step ST13 to the display unit 18. As a result, the genre of the facility is displayed on the display unit 18 as shown in FIG.

  Thereafter, when one genre is selected, the control unit 17 sends display data representing the classification of the facility searched in step ST13 to the display unit 18. Thereby, the facility classification is displayed on the display unit 18 as shown in FIG. FIG. 3C illustrates a case where “hospital” is selected in FIG. Subsequently, when one classification is selected, the control unit 17 sends display data representing the facility searched in step ST13 to the display unit 18. Thereby, the facility is displayed on the display unit 18 as shown in FIG.

  Next, the user selects a favorite facility for each genre (step ST15). That is, the user operates the operation input unit 13 to select a favorite facility from the facilities displayed on the display unit 18. Thereby, data representing the selected facility is sent to the control unit 17 as operation data.

  Next, the selected facility is set as a registration location (step ST16). That is, the control unit 17 stores the facility selected in step ST15 in the ROM 14 as a registration location. The registered locations registered in the ROM 14 can be displayed as a list, and the user can delete the registered locations according to his / her preference. This makes it possible to find registered locations that go frequently more quickly. Furthermore, when the place set as the registered place is not set as the destination for a certain period, it can be automatically deleted from the registered place.

  Next, it is checked whether or not the registration location setting is completed (step ST17). In the process of step ST17, for example, it is checked whether or not an “end” button displayed on the screen has been pressed. If it is determined in step ST17 that the registration location setting has not been completed, the sequence returns to step ST15, and after the undisplayed facilities among the facilities searched in step ST13 are displayed, the processing described above is performed. Is repeated. Then, when it is determined in step ST17 that the registered place setting has been completed, the registered place setting process around the home is ended.

  Next, route guidance start processing performed after home registration is completed will be described with reference to the flowchart shown in FIG.

  When the navigation device is powered on, route guidance start processing is executed. In this route guidance start process, first, it is checked whether or not the current location is around the home (step ST21). That is, the control unit 17 checks whether or not the position indicated by the current position data sent from the position detection unit 12 is within a few kilometers from the home.

  If it is determined in step ST21 that the current location is around the home, a screen for setting the destination from the registered location is displayed (step ST22). That is, the control unit 17 generates display data representing a screen for setting a destination from the registered location, and sends the display data to the display unit 18. Thereby, a destination setting screen as shown in FIG. 5 is displayed on the display unit 18.

  Next, it is checked whether or not a destination selection operation has been performed within a predetermined time (step ST23). That is, the control unit 17 indicates that the operation data sent from the operation input unit 13 indicates that the destination selection operation has been performed, and is within a predetermined time (several seconds) from the display of the destination setting screen. Find out if. If it is determined in step ST23 that the destination selection operation has been performed within a predetermined time, the destination is set from the registered location (step ST24). That is, one registered place selected from a plurality of registered places by the destination selecting operation in step ST23 is set as the destination.

  Next, route guidance is started (step ST25). That is, the control unit 17 starts processing for guiding a route from the current location to the destination according to the current location data sent from the location detection unit 12 and the map data read from the map data storage unit 16. Thereafter, the route guidance start process ends.

  If it is determined in step ST23 that the destination selection operation has not been performed within a predetermined time, the process proceeds to the normal activation screen (step ST26). That is, the destination setting and the route guidance start are not performed, and a transition is made to a screen for starting normal navigation. Thereafter, the route guidance start process ends.

  If it is determined in step ST21 that the current location is not in the vicinity of the home, it is checked whether or not the peripheral facility search and registration at the current location (point X) is performed (step ST27). If it is determined in this step ST27 that the peripheral facility search and registration at the current position (point X) is not performed, the sequence proceeds to step ST26, and after the process of transitioning to the normal activation screen is executed, the route guidance is performed. The start process ends.

  If it is determined in step ST27 that a peripheral facility search and registration at the current position (point X) is performed, a facility search around the current location is performed (step ST28). That is, the control unit 17 refers to the map data stored in the map data storage unit 16, and is a point indicated by the current position data sent from the position detection unit 12, that is, a facility within a few kilometers from the current position. Search for.

  Next, registration location setting processing is performed (step ST29). In this registration location setting process, the same process as the steps ST14 to ST17 in the flowchart shown in FIG. 2 (a process in which search results are displayed by genre and a user selects a favorite facility) is performed.

  Next, a list of registered locations at point X is created (step ST30). After that, the sequence proceeds to step ST26, and after the process for transitioning to the normal startup screen is executed, the route guidance start process ends.

  By the above processing, if the current position (point X) is outside the range of a few kilometers from your home, you can choose whether to search and register surrounding facilities at that point. A list of registered locations in the vicinity can be created.

  In step ST27, it is checked whether or not the current position is around the home or around the point X. If the current position is neither, a registered place list is created at a new point Y. In this way, the registration place list is sequentially created in units of home, point X, point Y,. When a new registration place is created in this way, on the destination setting screen displayed on the display unit 18 when the power is turned on, the number of tabs indicating the registration place increases as shown in FIG.

  Note that the facilities (XX, XX, □□,...) Displayed on the destination setting screen shown in FIG. Thus, it is configured to be able to sort in the order of the types indicated by the pressed buttons.

  As described above, according to the navigation device according to the first embodiment of the present invention, even a person unfamiliar with the operation of the device can easily set a familiar facility around the home as a “registered place”. Since it can be set, it will be possible to experience the convenience of the navigation device and eliminate allergies of navigation operations. In addition, when the navigation apparatus is activated, the registered place list is displayed for only a few seconds, so that destination setting can be prompted.
