Description

  The present invention relates to a navigation apparatus, and more particularly, to a navigation apparatus suitable for superimposing and displaying an icon indicating POI on a map.

  Conventionally, in navigation devices, an icon (hereinafter referred to as POI icon) indicating a POI (Points of Interest) such as a facility or a store is displayed on a map displayed using map information, and the position and type of the POI are indicated. By superimposing and displaying using the included POI information, it has been possible to provide the user with a POI as a stop-by destination by self-running, a landmark during traveling, a candidate for a destination or waypoint in route guidance, and the like.

  As described above, the POI icon has the convenience of being displayed on a map, while the POI is based on the recent increase in the capacity of map storage media and the diversification of methods for obtaining POI information (communication, etc.). It has been pointed out as a problem that the visibility of a map may be impaired due to an increase in the type of information, which causes a large number of POI icons to be displayed in a dense state on the map.

  To deal with such problems, for example, it may be possible for the user to individually set the type of POI to display the POI icon in advance. In many cases, complicated menu operations up to the lower layer are required, and the increase in the types of POI information described above promotes such complicated menu operations.

  Therefore, in order to realize the display of the POI icon that avoids such troublesome display setting and does not impair the visibility of the map, for example, the POI icons as shown in the following Patent Documents 1 to 3, for example, have been proposed. Various techniques have been proposed for automatically performing limited display.

  That is, in Patent Document 1, the user's preference according to the season, time or place is extracted based on the user's past POI selection history, and the POI icon that matches the extracted preference is displayed on the map. It has been proposed to be displayed.

  Japanese Patent Application Laid-Open No. 2004-228688 proposes to change and control the icon display state according to whether or not the facility is used, for example, to delete a POI icon corresponding to a used POI.

  Further, in Patent Document 3, it is proposed to display a POI icon according to the user's preference and behavior based on the usage frequency of the user's POI.

JP 2004-355075 A JP 2010-14455 A International Publication WO2006 / 126696

  By the way, it can be said that the user's needs for POI information tend to vary greatly depending on whether the user's current location, that is, the vehicle position, is inside or outside the user's living area. For example, when the position of the vehicle is in a region outside the user's living area such as a region far from the user's home, the user often leaves the daily life and travels. In the area, the user often searches for POI information having a strong connection with an action at a travel destination such as a sightseeing spot, a famous place, or an accommodation facility. On the other hand, when the position of the vehicle is near the user's home or in an area within the user's life area such as a commuting section in a car, the user often lives in daily life. Then, in many cases, the user searches for POI information having a strong connection with daily life such as a convenience store or a gas station. Of course, there is an individual difference in what kind of POI information is specifically searched, but it can be said that the user's needs tend to differ depending on the inside and outside of the living area.

  Therefore, when performing limited display of POI icons in consideration of map visibility, it is possible to increase the usefulness of POI icons by performing such limited display that reflects the needs of users according to the inside and outside of the living area. Desirable above.

  In this regard, paragraph 0014 of Patent Document 1 describes that the preference of the user varies depending on the place such as “I often visit a clothing store when visiting Ginza”. It is possible to display a POI icon corresponding to a different preference for each place.

  However, in Patent Document 1, for example, as shown in FIG. 8 and the like of the same document, POI preferences such as “Ginza” and “Shinjuku” are localized, and the user needs for POI information. However, it is not necessarily efficient because the preference is extracted based on the experience value without considering the unique tendency (commonality) depending on the inside and outside of the user's life zone. In Patent Document 1, it is difficult to determine the preference of POI over a wide area unless the user has considerable experience in selecting POI. There is a possibility that the display of the POI icon cannot be properly handled.

  Also, in Patent Document 2 and Patent Document 3, POI icons that reflect user preferences can be displayed in the same manner as Patent Document 1, but as in Patent Document 1, POI preferences can be displayed within and outside the living area. There is no suggestion that it will be managed separately.

  Therefore, there has been no effective proposal yet for a technology that efficiently displays limited POI icons that appropriately reflect the user's needs for POI information according to the user's life zone. .

  Therefore, the present invention has been made in view of the above points, and the limited display of POI icons for ensuring the visibility of a map can be performed in a user's living area depending on the driving situation without requiring a complicated operation. It is an object of the present invention to provide a navigation device that can be automatically identified and efficiently performed in a state that appropriately reflects the needs of users according to the inside and outside of the device.

  In order to achieve the above-mentioned object, a navigation device according to the present invention stores map information storage means storing map information, own vehicle position detection means for detecting the own vehicle position, and stored in the map information storage means. Based on the map information, a map display means for displaying a map indicating a predetermined area on the display section, a POI information storage means for storing POI information including the position and type of the POI, and a storage in the POI information storage means A navigation device comprising icon display means for superimposing and displaying an icon indicating the POI at a corresponding position on the map displayed by the map display means based on the POI information. A POI usage history showing the used POI together with its usage frequency corresponds to the use of the POI in the area of the user's living area. And a POI usage history recording means for recording in a storage unit in a state classified as corresponding to the use of the POI in an area outside the user's living area, and the icon display means is provided by the POI usage history recording means. Of the POI usage history for each of the recorded areas within and outside the living area, corresponding to the living area or the area outside the living area to which the own vehicle position detected by the own vehicle position detection means belongs Based on the POI usage history, the icons indicating the POI types within a predetermined number with a relatively high usage frequency are displayed. And according to such a structure, when the own vehicle position is in the area within the living area, POI usage history corresponding to the area within the living area is used, so that the POI that is frequently used in the area within the living area is used. The POI icon can be efficiently and limitedly displayed, and when the vehicle position is in an area outside the living area, the POI usage history corresponding to the area outside the living area can be used to A POI icon of a POI that is frequently used can be efficiently limitedly displayed.

  And a POI search means for searching for the POI based on the POI information, wherein the POI usage history recording means indicates that the position of the vehicle when the POI is detected by the POI search means is within the living area. If the POI of the same kind as the detected POI corresponds to the area within the living area and is not recorded in the storage unit, the unrecorded POI is stored in the area within the living area. In addition to recording in the storage unit in a state corresponding to the area, the use frequency value corresponding to one use is recorded in the storage unit in association with the unrecorded POI. When the POI of the same type as the POI has been recorded in the storage unit in a state corresponding to the area of the living area, the POI of the same type as the recorded POI in the area of the living area Every time it is detected, the POI usage history corresponding to the area in the living area is recorded by increasing the value of the usage frequency of the recorded POI by a value corresponding to the number of times of use. If the position of the vehicle when the POI is detected by the POI search means belongs to an area outside the living area, the POI of the same type as the detected POI corresponds to the area outside the living area If the unrecorded POI is recorded in the storage unit in a state in which the unrecorded POI is associated with the area outside the living area, the usage frequency corresponds to one use. Is recorded in the storage unit in association with the unrecorded POI, while the POI of the same type as the detected POI has been recorded in the storage unit in a state corresponding to the area outside the living area In each case, every time a POI of the same type as the recorded POI is detected in the area outside the living area, the use frequency value of the recorded POI is increased by a value corresponding to one use count. By doing so, the POI usage history corresponding to the area outside the living area may be recorded. With this configuration, the POI use history can be recorded using the detection result of the POI search means reflecting the user's needs for the POI information, and the number of POI detections is reflected in the use frequency value. By doing so, an accurate use frequency can be recorded.

  And a POI selection means for selecting the POI on the map, wherein the POI use history recording means indicates that the position of the vehicle when the POI is selected by the POI selection means is within the living area. If the POI of the same type as the selected POI corresponds to the area in the living area and is not recorded in the storage unit, the unrecorded POI is stored in the area in the living area. In addition to recording in the storage unit in a state corresponding to the area, the use frequency value corresponding to one use is recorded in the storage unit in association with the unrecorded POI. When the POI of the same type as the POI has been recorded in the storage unit in a state corresponding to the area of the living area, the PO of the same type as the recorded POI in the area of the living area Each time is selected, the usage frequency value of the recorded POI is increased by a value corresponding to the number of times of use, thereby recording the POI usage history corresponding to the area in the living area. If the position of the vehicle when the POI is selected by the POI selection means belongs to an area outside the living area, the POI of the same type as the selected POI is placed in the area outside the living area. When the corresponding unrecorded POI is recorded in the storage unit, the unrecorded POI is recorded in the storage unit in a state corresponding to the area outside the living area, and the usage is equivalent to one use. The frequency value is recorded in the storage unit in association with the unrecorded POI, while the POI of the same type as the selected POI is recorded in the storage unit in a state corresponding to the area outside the living area. In this case, every time a POI of the same type as the recorded POI is selected in the area outside the living area, the value of the usage frequency of the recorded POI is a value corresponding to one use count. The POI usage history corresponding to the area outside the living area may be recorded by increasing the number. With this configuration, the POI selection history reflecting the user's needs for the POI information can be used to record the POI usage history, and the number of POI selections is reflected in the usage frequency value. By doing so, an accurate use frequency can be recorded.

  Furthermore, it comprises a traffic history recording means for recording in the storage section a traffic history showing the traffic area where the vehicle has traveled along with its traffic frequency, and the POI usage history recording means is the traffic recorded by the traffic history recording means. Among the traffic areas indicated by history, the traffic area having a traffic frequency of a threshold value or more is set as the area within the living area, and the traffic area having the traffic frequency less than the threshold and the area where the traffic history does not exist, It may be an area outside the living area. And if comprised in this way, the area | region suitable as an area | region inside and outside a living area can be selected in consideration of a user's daily action | operation range.

  Moreover, the said traffic history recording means may record the said traffic area | region per mesh. And if comprised in this way, the area | region in the living area can be managed simply by a rough management unit.

  Further, the POI usage history recording means sets an area within a predetermined distance from the position of the user's home as an area within the living area, and an area farther than the predetermined distance from the position of the home as an area outside the living area It is good. And if comprised in this way, the area | region suitable as an area | region inside and outside a living area can be selected in consideration of the distance from a user's home.

  Furthermore, the POI includes weighting means for weighting each POI type corresponding to each of the living area and the non-living area, and the icon display means determines the frequency of use. The type of the POI on which the icon is to be displayed may be determined in consideration of the result of the weighting by the corresponding weighting means. And if comprised in this way, when the own vehicle position is in the area in the living area, the limitation of the POI icon considering not only the use frequency in the area in the living area but also the weighting according to the area in the living area When the vehicle position is in an area outside the living area, the POI icon can be limitedly displayed considering not only the frequency of use in the area outside the living area but also the weighting according to the area outside the living area. It can be carried out.

  In addition, the weighting unit performs the weighting that makes it easy to display the icon for the POI that is considered to have a strong connection with daily life, as the weighting according to the region within the living area. In addition, for the POI of a type that is considered to be strongly linked to an action at a travel destination, the weighting that makes it difficult to display the icon is performed, and the weighting according to the area outside the living area is used as a daily weight. For the POI of a type that is considered to have a strong connection with life, the weighting that makes it difficult to display the icon is performed, and for the POI of a type that is considered to have a strong connection with an action at a travel destination On the other hand, the weighting may be performed so that the icon is easily displayed. And if comprised in this way, when the own vehicle position exists in the area | region within the living area, it will be easy to display the POI icon considered that the connection with the daily life suitable for the user's needs in this area is strong. On the other hand, when the vehicle position is in an area outside the living area, it is possible to easily display a POI icon that is considered to be strongly linked to an action at a travel destination suitable for the user's needs in this area. it can.

  Furthermore, the icon display means is a map that does not include the vehicle position even when the map that does not include the detected vehicle position is displayed by scrolling the map. The type of POI displaying the icon above remains the same as the type of POI determined based on the POI usage history corresponding to the living area or the area outside the living area to which the vehicle position belongs. May be maintained. And if comprised in this way, the complicated process which switches frequently the POI usage log | history used for the display of a POI icon according to map scroll can be avoided.

  Furthermore, the icon display means may display the icon based on the POI usage history when the automatic display mode is set as the icon display mode. And if comprised in this way, in the automatic display mode which a user does not require complicated setting operation, the POI icon reflecting the user's needs according to the inside and outside of the living area can be displayed.

  According to the present invention, the limited display of the POI icon for ensuring the visibility of the map is performed in a state that appropriately reflects the user's needs according to the inside and outside of the user's living area without requiring a complicated operation. Can be done efficiently.

At this time, for example, the POI search unit 22 may search for a POI corresponding to the input operation of the operation unit 5 on the search screen 23 after displaying the search screen 23 as shown in FIG. 4.

  Returning to FIG. 2, the navigation CPU 10 has a POI usage history recording unit 24 as a POI usage history recording means as one of its functional blocks. This POI usage history recording unit 24 sets a POI usage history indicating the POI used by the user together with its usage frequency after setting each area within the user's living area and outside the living area (hereinafter referred to as a usage history management area). The hard disk drive 11 serving as a storage unit is classified into one corresponding to use of POI in the usage history management area in the living area and one corresponding to use of POI in the usage history management area outside the living area. It comes to record. At this time, the POI usage history recording unit 24 records the POI usage history by the following two recording methods.

  First, the first recording method is a method of recording the detection result of the POI search unit 22 as a POI usage history.

  Specifically, in the first recording method, when the POI use history recording unit 24 belongs to the use history management area in the living area when the POI is detected by the POI search unit 22, A first determination is made as to whether or not a POI of the same type as the detected POI has not been recorded in the hard disk drive 11 as a POI usage history corresponding to the usage history management area in the living area. If a positive determination result (determination result indicating that recording is not performed) is obtained in the first determination, the POI usage history recording unit 24 converts the POI determined to be unrecorded within the living area. In a state corresponding to the usage history management area, it is recorded in the hard disk drive 11 as a part of the POI usage history corresponding to the usage history management area in the living area. The POI content recorded at this time may be a POI type (category) such as a convenience store, a gas station, a famous place, and a sightseeing spot. As for convenience stores, there are many subdivided brands in the same category, and for POIs that tend to be dense within a given area, Recording may be performed. However, in this case, the brand is included in one aspect of the POI type. In addition, when recording such an unrecorded POI, the POI use history recording unit 24 associates the value of the use frequency corresponding to one use with the unrecorded POI, and maps it within the living area. Recorded in the hard disk drive 11 as a part of the POI usage history corresponding to the usage history management area. On the other hand, when a negative determination result (determination result indicating that recording has been performed) is obtained in the first determination, the POI usage history recording unit 24 has a POI of the same type as the POI determined to be recorded. Each time it is detected in the usage history management area in the living area, the corresponding usage frequency value in the POI usage history corresponding to the usage history management area in the living area is increased by a value corresponding to the number of times of use. In this way, the POI usage history corresponding to the usage history management area in the living area is recorded by the first recording method.

  Further, in the first recording method, the POI usage history recording unit 24 detects the POI use history recording unit 24 when the POI search unit 22 detects the POI when it belongs to the usage history management area outside the living area. A second determination is made as to whether a POI of the same type as the POI is not recorded in the hard disk drive 11 as a POI usage history corresponding to a usage history management area outside the living area. When a positive determination result (determination result indicating that recording has not been performed) is obtained in the second determination, the POI usage history recording unit 24 sets the POI determined to be unrecorded as being out of the living area. In a state corresponding to the usage history management area, it is recorded in the hard disk drive 11 as a part of the POI usage history corresponding to the usage history management area outside the living area. The POI content recorded at this time may be the POI type (category / brand) as in the case of the first determination. Further, as in the case of the first determination, the POI usage history recording unit 24 records the value of the usage frequency corresponding to one use when the unrecorded POI is recorded. Is recorded in the hard disk drive 11 as a part of the POI usage history corresponding to the usage history management area outside the living area. On the other hand, when a negative determination result (determination result indicating that recording has been performed) is obtained in the second determination, the POI usage history recording unit 24 has a POI of the same type as the POI determined to be recorded. Each time it is detected in the usage history management area outside the living area, the corresponding usage frequency value in the POI usage history corresponding to the usage history management area outside the living area is increased by a value corresponding to the number of times of use. In this way, the POI usage history corresponding to the usage history management area outside the living area is recorded by the first recording method.

  Next, the second recording method is a method of recording a POI (POI icon) selection result on the map by the operation unit 5 as a POI usage history.

  Specifically, in the second recording method, the POI usage history recording unit 24 selects the POI when the position of the vehicle when the POI is selected on the map belongs to the usage history management area in the living area. A third determination is made as to whether or not a POI of the same type as the POI is not recorded in the hard disk drive 11 as a POI usage history corresponding to the usage history management area in the living area. When a positive determination result (determination result indicating that recording is not performed) is obtained in the third determination, the POI usage history recording unit 24 determines that the POI (POI type) is determined to be unrecorded. Is recorded in the hard disk drive 11 as a part of the POI usage history corresponding to the usage history management area in the living area in a state corresponding to the usage history management area in the living area. At this time, the POI usage history recording unit 24 associates the value of the usage frequency corresponding to one usage count with the unrecorded POI, and the POI usage history corresponding to the usage history management area in the living area. Is recorded on the hard disk drive 11. However, at this time, if a certain POI has been recorded in the hard disk drive 11 as a POI usage history corresponding to the usage history management area in the living area by the first recording method, the selected POI of the same type as that POI is In the third determination, it is treated as already recorded. The same applies to the case where the POI recorded as the POI usage history corresponding to the usage history management area in the living area by the second recording method is handled in the first determination in the first recording method described above. On the other hand, if a negative determination result (determination result indicating that recording has been performed) is obtained in the third determination, the POI usage history recording unit 24 has a POI of the same type as the POI determined to be recorded. Each time the usage history management area in the living area is selected, the corresponding usage frequency value in the POI usage history corresponding to the usage history management area in the living area is increased by a value corresponding to the number of times of use. In this way, the POI usage history corresponding to the usage history management area in the living area is recorded by the second recording method.

  In the second recording method, the POI usage history recording unit 24, when the position of the vehicle when the POI is selected on the map belongs to the usage history management area outside the living area, A fourth determination is made as to whether or not the same kind of POI is recorded in the hard disk drive 11 as a POI usage history corresponding to a usage history management area outside the living area. When a positive determination result (determination result indicating that recording is not performed) is obtained in the fourth determination, the POI usage history recording unit 24 determines that the POI (POI type) is determined to be unrecorded. Is recorded in the hard disk drive 11 as a part of the POI usage history corresponding to the usage history management area outside the living area in a state corresponding to the usage history management area outside the living area. At this time, the POI usage history recording unit 24 associates the value of the usage frequency corresponding to one usage with the unrecorded POI, and the POI usage history corresponding to the usage history management area outside the living area. Is recorded on the hard disk drive 11. However, at this time, if a certain POI has already been recorded in the hard disk drive 11 as a POI usage history corresponding to the usage history management area outside the living area by the first recording method, the selected POI of the same type as that POI is In the fourth determination, it is handled as already recorded. The same applies to the case where the POI recorded as the POI usage history corresponding to the usage history management area outside the living area by the second recording method is handled in the second determination in the first recording method described above. On the other hand, if a negative determination result (determination result indicating that recording has been performed) is obtained in the fourth determination, the POI usage history recording unit 24 has a POI of the same type as the POI determined to be recorded. Each time the usage history management area outside the living area is selected, the corresponding usage frequency value in the POI usage history corresponding to the usage history management area outside the living area is increased by a value corresponding to one usage count. In this way, the POI usage history corresponding to the usage history management area outside the living area is recorded by the second recording method.

  Furthermore, as shown in FIG. 2, the navigation CPU 10 has a weighting unit 25 as weighting means as one of its functional blocks. The weighting unit 25 weights each POI indicated by the POI data for each type of POI corresponding to each usage history management area within and outside the living area. At this time, the weighting unit 25 weights the POI icons so that the POI icons are easily displayed on the types of POIs that are considered to have a strong connection with daily life, as the weighting according to the usage history management area in the living area. At the same time, weighting that makes it difficult to display the POI icon is performed on a type of POI that is considered to be strongly linked to the action at the travel destination. On the other hand, the weighting unit 25 performs weighting that makes it difficult to display the POI icon for a type of POI that is considered to have a strong connection with daily life as weighting according to the usage history management area outside the living area. In addition, weighting is performed so that a POI icon is easily displayed on a type of POI that is considered to be strongly linked to an action at a travel destination. Such weighting by the weighting unit 25 may be performed by setting a weighting coefficient for each POI. Here, FIG. 5 shows an example of setting the weighting factor according to each usage history management area in the living area and outside the living area, together with the POI usage history corresponding to each usage history management area. Specifically, each POI usage history in FIG. 5 is obtained by associating a POI usage frequency value with a POI type, and this usage frequency value is stored in the corresponding usage history management area. This corresponds to the total number of times of POI detection by the POI search unit 22 and the number of POI selections on the map. In FIG. 5, for each type of POI included in each POI usage history, a weighting factor for each type corresponding to the usage history management area is set. That is, as shown in FIG. 5, in the POI usage history corresponding to the usage history management area in the living area, the weight coefficient of the convenience store or gas station (GS) that is strongly linked to daily life is set to a large value. On the other hand, in the POI usage history corresponding to the usage history management area outside the living area, those weighting factors are set to a small value. On the other hand, in the POI usage history corresponding to the usage history management area in the living area, the weight coefficient of the sights and sightseeing spots that are strongly linked to the action at the travel destination is set to a small value. Thus, in the POI usage history corresponding to the usage history management area outside the living area, the weighting coefficient is set to a large value. However, the weighting factor is set for all types of POI according to each usage history management area regardless of whether or not the POI usage history is recorded (that is, whether or not the POI is detected or selected), and is stored in the hard disk drive 11. Just remember.

  In the present embodiment, the POI icon drawing unit 20 includes the vehicle position calculated by the vehicle position calculation unit 18 among the POI usage history for each usage history management area recorded by the POI usage history recording unit 24. Based on the POI usage history corresponding to the usage history management area to which the user belongs, a limited number of types of POI icons having a relatively high usage frequency are displayed in a limited manner. However, at this time, the POI icon drawing unit 20 adds the weighting result by the weighting unit 25 corresponding to the usage frequency indicated by the POI usage history to the priority order for the POI type on which the POI icon should be displayed. The POI icon is limitedly displayed according to the determined priority order. In determining the priority order, for example, the POI type having a larger value obtained by multiplying the use frequency value by the weighting factor may be set higher. In addition, the above-mentioned “types within a predetermined number” refers to the number of POI types with the highest priority existing in the map area after the maximum number of POI types for displaying POI icons is set to a predetermined number. Is less than the predetermined number, it means that only the upper number of types of POIs less than the predetermined number existing in the map area may be displayed as icons. Further, the types of POI icons that are limitedly displayed may be within three types. Furthermore, when the POI usage history such as the beginning of use of the navigation device 1 is not obtained, the priority order may be determined exceptionally based only on the magnitude relationship of the weighting factors.

  According to such a configuration, when the position of the vehicle is in the usage history management area in the living area, the weighting unique to the living area is obtained by using the POI usage history corresponding to this area and the weighting result. It is possible to efficiently display limited types of POI icons that are frequently used. For example, as shown in FIG. 6A, a POI icon 27 indicating a convenience store, a gas station, and an ATM can be limitedly displayed on the vehicle position surrounding map 26 in an area within the living area. On the other hand, when the vehicle position is in the usage history management area outside the living area, the POI usage history corresponding to this area and the weighting result are used, so that the type of usage is high according to the weighting unique to the outside of the living area The POI icon can be efficiently limitedly displayed. For example, as shown in FIG. 6B, in a region outside the living area, a POI icon 28 indicating a famous place, a sightseeing spot, and an accommodation facility can be limitedly displayed on the vehicle position surrounding map 26. Further, according to the present embodiment, as the POI usage history, the detection result of the POI search unit 22 and the selection result on the map in which the user's needs for the POI information are appropriately reflected can be used. In the area, a POI icon suitable for the user's preference can be displayed.

  In addition to the above configuration, the POI usage history recording unit 24 can set the usage history management areas in the living area and the outside of the living area according to the following plurality of setting methods.

  That is, the first setting method is a method of setting the usage history management area based on the traffic frequency of the own vehicle. In this first setting method, the navigation CPU 10 is caused to function as a passing history recording means, and the navigation CPU 10 determines a traffic area that is an area in which the host vehicle has passed based on the calculation result of the host vehicle position calculation unit 18. The traffic history shown together with the traffic frequency is recorded in the hard disk drive 11 as a storage unit. At this time, the navigation CPU 10 records the traffic area in units of mesh (for example, secondary mesh). Then, the POI usage history recording unit 24 sets, as the usage history management area in the living area, an area where the traffic frequency indicated by the traffic history recorded by the navigation CPU 10 is equal to or greater than the threshold, and the area where the traffic frequency is less than the threshold. An area where the traffic history itself does not exist is set as a usage history management area outside the living area. Specifically, the navigation CPU 10 determines the information of the unrecorded mesh (for example, if the mesh to which the own vehicle passes, that is, the mesh to which the own vehicle position belongs, is not recorded in the hard disk drive 11 as the traffic history) Coordinate range information) is recorded in the hard disk drive 11 in association with the value of the traffic frequency corresponding to one pass. On the other hand, when the mesh on which the vehicle is traveling has been recorded in the hard disk drive 11 as the traffic history, the value of the traffic frequency corresponding to the mesh is set once each time the recorded mesh is passed. Increase by a value corresponding to the number of times of traffic. However, the process of recording the mesh information and the process of increasing the value of the traffic frequency are limited to once per day for the same mesh, and the first one when passing the same mesh multiple times during the same day Only the traffic of is added to the traffic frequency, and the second and subsequent traffic is ignored. Then, by repeating the recording of the mesh information or the increase in the value of the traffic frequency over a plurality of days, the traffic history is recorded so as to be sequentially updated. In the traffic history, when the recording date of each mesh or the traffic frequency is updated, the updated date may be recorded. In this case, the mesh with the low traffic frequency may be deleted from the traffic history in ascending order of information. In the first setting method, based on the traffic history recorded in this way, for example, an area corresponding to a mesh that has passed for 30 days in the past 100 days is set as a use history management area in the living area. The other area is set as a usage history management area outside the living area.

  Next, the second setting method is a method of setting the usage history management area based on the distance from the home position of the user registered in advance. In the second setting method, the navigation CPU 10 sets an area within a predetermined distance from the user's home position (for example, an area within a radius of 50 km from the home position) as a use history management area within the living area, and the user An area that is more than the predetermined distance from the home position is set as a usage history management area outside the living area.

  Next, the third setting method is a setting method that hybridizes the first setting method and the second setting method. In this third method, considering that there is no traveling experience yet at the start of use of the navigation apparatus 1, first, the use history management area is initially set using the second setting method. Then, from such an initial setting state, the recording of the traffic history in the first setting method is proceeded, and when a mesh having a high traffic frequency exists in the process, the usage history management outside the living area is detected. If it is initially set as an area, it is reset as a use history management area in the living area. At this time, if it is found that the predetermined area near the home that was initially set as the use history management area in the living area is not actually passed in the process of recording the travel history, The usage history management area outside the living area may be reset.

  As to which of these setting methods is used, an optimum setting method corresponding to the concept may be selected. In addition, the usage history management area may be set by, for example, setting a flag indicating which usage history management area is in or outside the living area in association with each mesh of the map data. .

  In the present embodiment, the POI icon drawing unit 20 displays the POI icon based on the above-described POI usage history when the above-described “automatic” display mode is set as the POI icon display mode. It has become.

  Furthermore, the POI icon drawing unit 20 includes the vehicle position even when the map is scrolled using the operation unit 5 and a map that does not include the vehicle position is displayed. The POI type for displaying the POI icon on a map that does not exist may be kept the same type as the POI type determined based on the POI usage history corresponding to the usage history management area to which the vehicle position belongs. .

  Returning to FIG. 2, the navigation CPU 10 has a destination setting unit 30 as one of its functional blocks. The destination setting unit 30 displays various operation screens for setting a navigation destination on the display 6 and then sets a destination according to the operation of the operation unit 5 for the displayed operation screen. It has become. The operation screen includes the above-described POI search screen 23 and a selectable POI icon.

  As shown in FIG. 2, the navigation CPU 10 has a route search unit 32 as one of its functional blocks. The route search unit 32 is set in advance from the vehicle position calculated by the vehicle position calculation unit 18 to the destination set by the destination setting unit 30 based on the map data stored in the hard disk drive 11. The optimum route according to the route search condition is searched. The route search condition may be set by default, or may be set by an input operation using the operation unit 5 by the user. Then, the route search unit 32 presents the searched optimum route to the user as a guide route candidate by display on the display 6.

  Furthermore, as shown in FIG. 2, the navigation CPU 10 has a route guidance unit 33 as one of its functional blocks. When an input operation using the operation unit 5 for setting the optimum route presented by the route searching unit 32 is performed, the route guidance unit 33 sets the optimum route as the guidance route. ing. The setting of the guide route may be performed by storing information on the guide route, such as a link and a destination, in the RAM 14 or the like. The route guiding unit 33 starts route guidance according to the set guidance route after setting the guidance route. The route guidance is performed by displaying an enlarged view of the intersection on the display 6 or by outputting a voice for turning right and left at the intersection via the speaker 7.

  Next, the operation of this embodiment will be described.

  In this embodiment, first, according to the flowchart shown in FIG. 7, management of the traffic history for recording the POI usage history is performed.

  That is, first, in step 1 (ST1) of FIG. 7, whether or not the vehicle is traveling on a general road according to the calculation result of the vehicle position calculation unit 18 by the navigation CPU 10 (function of the travel history recording means). judge. If a positive determination result is obtained in step 1 (ST1), the process proceeds to step 2 (ST2). If a negative determination result is obtained, the process ends. Here, when riding on an expressway, the user often goes to an area outside the living area, and the possibility that the expressway is frequently used is low. The determination in step 1 (ST1) has the significance of excluding the mesh corresponding to such a highway from the record of the traffic history and the set of the use history management area in the living area in advance. However, since there is a case where the highway is used for daily commuting, the determination in Step 1 (ST1) may be performed as necessary.

  Next, in step 2 (ST2), the navigation CPU 10 determines whether or not a new mesh to which the own vehicle position belongs has been acquired along with the change in the own vehicle position. If a positive determination result is obtained in step 2 (ST2), the process proceeds to step 3 (ST3). If a negative determination result is obtained, step 2 (ST2) is repeated.

  Next, in step 3 (ST3), the process proceeds to a recording process of a traffic history for the new mesh acquired in step 2 (ST2).

  This traffic history recording process is performed according to the flowchart shown in FIG. That is, first, at step 11 (ST11) in FIG. 8, the navigation CPU 10 determines whether or not the recording process is the first recording today. If a positive determination result is obtained in step 11 (ST11), the process proceeds to step 12 (ST12). If a negative determination result is obtained, the process ends.

  Next, in step 12 (ST12), the navigation CPU 10 determines whether or not the new mesh has not been recorded as a traffic history. If a positive determination result is obtained in step 12 (ST12), the process proceeds to step 13 (ST13), and if a negative determination result is obtained, the process proceeds to step 16 (ST16).

  Here, the processing after step 13 (ST13) will be described first. First, in step 13 (ST13), the number of meshes recorded as the travel history by the navigation CPU 10 is the recording area for the travel history ( It is determined whether or not a predetermined upper limit is reached from the relationship with the buffer. If a positive determination result is obtained in step 13 (ST13), the process proceeds to step 14 (ST14). If a negative determination result is obtained, the process proceeds to step 15 (ST15).

  Next, in step 14 (ST14), the navigation CPU 10 deletes the meshes whose traffic frequency is equal to or less than the threshold value from the meshes recorded in the traffic history from the traffic history in order of oldest information, and proceeds to step 15 (ST15). move on.

  In step 15 (ST15), the navigation CPU 10 records the new mesh as a traffic history in association with a traffic frequency value corresponding to a traffic count of 1 and ends the process.

  On the other hand, in step 16 (ST16), the navigation CPU 10 increments the value of the traffic frequency of the traffic history corresponding to the new mesh by the value corresponding to the number of times of travel and ends the process.

  Then, under such management of the traffic history, the POI usage history recording unit 24 performs a usage history management area setting process according to the flowchart shown in FIG.

  That is, first, in step 21 (ST21) of FIG. 9, the POI usage history recording unit 24 individually determines whether or not there is a travel history for all meshes of the map data. And about the mesh from which the positive determination result was obtained in step 21 (ST21), it progresses to step 22 (ST22), and about the mesh from which the negative determination result was obtained, it progresses to step 24 (ST24).

  Next, in step 22 (ST22), whether or not the corresponding traffic frequency value is equivalent to a predetermined number of times or more for all meshes recorded in the traffic history by the POI usage history recording unit 24. Judge individually. And about the mesh from which the positive determination result was obtained in step 22 (ST22), it progresses to step 23 (ST23), and about the mesh from which the negative determination result was obtained, it progresses to step 24 (ST24).

  Next, in step 23 (ST23), the POI usage history recording unit 24 sets the mesh for which a positive determination result is obtained in step 22 (ST22) as the usage history management area in the living area, and ends the processing. To do.

  On the other hand, in step 24 (ST24), the mesh for which a negative determination result is obtained in step 21 (ST21) or step 22 (ST22) by the POI usage history recording unit 24 is used as a usage history management area outside the living area. Set and finish the process.

  However, the setting process of FIG. 9 is based on the first setting method described above, and the second setting method or the third setting method described above may be used depending on the concept.

  Then, after setting the usage history management areas in the living area and outside the living area in this way, the POI usage history recording unit 24 performs the POI usage history recording process according to the flowchart shown in FIG.

  That is, first, in step 31 (ST31) of FIG. 10, the POI usage history recording unit 24 determines whether POI information is detected by the POI search unit 22 or a POI icon is selected on the map. If a positive determination result is obtained in step 31 (ST31), the process proceeds to step 32 (ST32). If a negative determination result is obtained, step 31 (ST31) is repeated.

  Next, in step 32 (ST32), the POI usage history recording unit 24 uses the vehicle history in the living area in which the vehicle position when the detection / selection in step 31 (ST31) is performed is set as described above. It is determined whether or not it belongs to the management area. If a positive determination result is obtained in step 32 (ST32), the process proceeds to step 33 (ST33), and if a negative determination result is obtained, the process proceeds to step 36 (ST36).

  Here, the processing after step 33 (ST33) will be described first. First, in step 33 (ST33), the POI usage history recording unit 24 uses the same type of POI detected / selected in step 31 (ST31). It is determined whether or not the POI is unrecorded as the POI usage history corresponding to the usage history management area in the living area (first / third determination). If a positive determination result is obtained in step 33 (ST33), the process proceeds to step 34 (ST34), and if a negative determination result is obtained, the process proceeds to step 35 (ST35).

  Next, in step 34 (ST34), the POI usage history recording unit 24 associates the POI detected / selected in step 31 (ST31) with the value of the usage frequency corresponding to one use, and is in the living area. Is recorded as a POI usage history corresponding to the usage history management area, and the process is terminated.

  On the other hand, in step 35 (ST35), the usage corresponding to the POI detected / selected in step 31 (ST31) among the POI usage history corresponding to the usage history management area in the living area by the POI usage history recording unit 24. The frequency value is increased by a value corresponding to the number of times of use, and the process is terminated.

  Next, the processing after step 36 (ST36) will be described. First, in step 36 (ST36), the POI usage history recording unit 24 uses the same kind of POI detected / selected in step 31 (ST31). It is determined whether the POI is unrecorded as the POI usage history corresponding to the usage history management area outside the living area (second / fourth determination). If a positive determination result is obtained in step 36 (ST36), the process proceeds to step 37 (ST37), and if a negative determination result is obtained, the process proceeds to step 38 (ST38).

  Next, in step 37 (ST37), the POI usage history recording unit 24 associates the POI detected / selected in step 31 (ST31) with a use frequency value corresponding to one use, and is out of the living area. Is recorded as a POI usage history corresponding to the usage history management area, and the process is terminated.

  On the other hand, in step 38 (ST38), the usage corresponding to the POI detected / selected in step 31 (ST31) among the POI usage history corresponding to the usage history management area outside the living area by the POI usage history recording unit 24. The frequency value is increased by a value corresponding to the number of times of use, and the process is terminated. The weighting for each POI in the POI usage history depends on each usage history management area at the stage before each POI is recorded as the POI usage history (for example, when the setting of the usage history management area is completed or when the change is completed). You can do it in advance. The specific contents of the weighting are as described above.

  Then, after the POI usage history is recorded in this way, the POI icon drawing unit 20 performs POI icon display processing according to the flowchart shown in FIG.

  That is, first, in step 41 (ST41) in FIG. 11, the POI icon drawing unit 20 determines whether or not the automatic display mode is set as the POI icon display mode. If a positive determination result is obtained in step 41 (ST41), the process proceeds to step 42 (ST42), and if a negative determination result is obtained, the process proceeds to step 46 (ST46).

  Here, the processing after step 42 (ST42) will be described first. First, at step 42 (ST42), the POI icon drawing unit 20 uses the calculation result of the vehicle position calculation unit 18 and the POI usage history recording unit 24. Based on the setting state of the usage history management area, it is determined whether or not the vehicle position belongs to the usage history management area in the living area. If a positive determination result is obtained in step 42 (ST42), the process proceeds to step 43 (ST43), and if a negative determination result is obtained, the process proceeds to step 45 (ST45).

  Next, in step 43 (ST43), the POI icon drawing unit 20 displays the POI icon based on the POI usage history corresponding to the usage history management area in the living area and the weighting result corresponding to the POI usage history. The priority order for the type of the POI to be determined is determined, and the process proceeds to step 44 (ST44).

  On the other hand, in step 45 (ST45), the POI icon drawing unit 20 displays the POI icon based on the POI usage history corresponding to the usage history management area outside the living area and the weighting result corresponding to the POI usage history. The priority order for the type of the POI to be determined is determined, and the process proceeds to step 44 (ST44).

  However, the priority order may be determined in advance when recording or updating the POI usage history.

  Next, in step 44 (ST44), the POI icon drawing unit 20 displays a predetermined number of types of POI icons within the predetermined number according to the priority order determined in step 43 (ST43) or step 45 (ST45). The display is limited to the map around the vehicle displayed by, and the process ends.

  On the other hand, in step 46 (ST46), the POI icon drawing unit 20 displays the POI icon according to the set display mode other than the automatic display mode, and the process is terminated.

  As described above, according to the present invention, by using the POI usage history corresponding to the usage history management area outside or within the living area to which the vehicle position belongs, the POI having a high usage frequency in the living area / outside the living area. The POI icon can be efficiently and limitedly displayed, so that the limited display of the POI icon for ensuring the visibility of the map can be performed without requiring a complicated operation, and the user needs according to the inside and outside of the user's living area Can be efficiently performed in a state in which is properly reflected.

  In addition, this invention is not limited to embodiment mentioned above, A various change can be made in the limit which does not impair the characteristic of this invention.

  For example, the usage history management area within the living area and the usage history management area outside the living area are each further divided into a plurality of small areas according to a plurality of levels based on traffic frequency, weighting factor, or distance from the home position. May be managed. In this case, the limited display of the POI icon is performed based on the POI usage history of one small area to which the vehicle position belongs. However, even if the usage history management area is divided so that the original significance of managing the usage history management area separately in the living area and outside the living area is not diluted, the number of divisions is a predetermined number (for example, 2 It is desirable to stop at division).
