Description

  The present invention relates to a map information display device, a facility information display method, a facility information display program, and a recording medium thereof, and more specifically, a map information display device that displays facility information on a map, a facility information display method, and a facility information display. The present invention relates to a program and its recording medium.

In recent years, in a map information display device equipped with a liquid crystal display device or the like that is mounted on a car or the like and displays a map, it is only necessary to calculate its position by GPS (Global Positioning System) and display its position on a map. In addition, navigation devices that display a route to a destination and perform route guidance are widely used. Such a navigation device holds information on peripheral facilities associated with points on a map called POI (Point of Interest), and displays the information included in the POI with the map information on the screen. As a result, more information can be provided to the driver or the like.

  This POI information is generally displayed on a map by a small image called an icon. Therefore, especially when a map is displayed in an urban area, since there are many facilities at a nearby point, the displayed map will be filled with POI icons. If this occurs during the execution of the navigation function, it will interfere with the route guidance, which is the original function of the device. In order to cope with such a situation, when approaching a corner or the like as a road guide point, a method of hiding other than the POI icon that serves as a road guide sign has been proposed (see Patent Document 1). ).

  The above-described conventional technique is excellent in smoothly performing route guidance, which is an original function of the navigation device. However, displaying many POI icons, regardless of whether or not the navigation function is being executed, makes it difficult to check the map information due to the display of icons that are not necessary for the user. Therefore, the load on a CPU (Central Processing Unit) is large, and the speed until rendering is often slowed down.

  Also, there is a method of displaying only the POI icon set by the user, but it is easy for the user to reset the POI icon to be displayed every time the user's preference changes. Not a function.

  The present invention has been made in view of the above circumstances, and is a map information display device capable of appropriately displaying POI facility information according to user's preference and behavior without special setting by the user. An object is to provide a facility information display method, a facility information display program, and a recording medium thereof.

  According to a first aspect of the present invention, there is provided a weighting variable correcting means for correcting a value of a weighting variable associated with the facility upon occurrence of a predetermined event related to the facility; a map displayed based on the weighting variable Display facility information determining means for determining facility information to be displayed together with; facility information display means for displaying the facility information determined by the display facility information determining means together with the map; .

Here, the “predetermined event related to a facility” specifically means a predetermined event that is related to a facility such as staying at the location where the facility is located or searching for the facility. ing. In addition, the “weighting variable” may be a counter that records the number of occurrences of an event, a variable such as a flag that is set when a certain event occurs, or a variable based on another weighting method. Further, “based on a weighting variable” means that the weighting variable is handled as one requirement in the process of determining the facility information to be displayed. Further, “facility information” means information about the facility, specifically, location information of the facility, image information of an icon, etc., so-called POI (Point Of Interest).
Information that can be acquired from the information in ().

  Therefore, by displaying the facility information based on the experience of occurrence of a predetermined event, it is possible to display the facility information according to the user's preference and behavior on the map without special setting by the user. .

  In this map information display device, one of the predetermined events may be a search for the facility. Here, “facility search” means a search for a specific facility by a function of the map information display device. Therefore, weighting the facilities that the user is interested in can be reflected in the display.

  The map information display device further includes current position information acquisition means for acquiring current position information, and one of the predetermined events is a stay at the current position acquired by the current position information acquisition means. It can be. Here, the “current position information acquisition means” includes a method based on calculation of position information using a GPS satellite and other methods based on acquisition of current position information. Therefore, by weighting the facility where the user stops, it can be reflected in the display.

  The map information display device further includes navigation means for displaying a route by designating a destination and, if necessary, a waypoint, and the predetermined event includes the designation of the destination and the Including designation of waypoints. Therefore, weighting the facilities set by the user as the waypoints and destinations can be reflected in the display.

  Further, in this map information display device, it is mounted on a moving means that requires replenishment of energy, and one of the predetermined events occurs when it is determined that the replenishment has been performed, and the facility information display means includes: When it is determined that the replenishment is necessary, the facility information for the replenishment may be displayed. Here, the “moving means that requires replenishment of energy” is generally an automobile that uses gasoline as fuel, and other moving means that require replenishment of energy, for example, electricity that requires charging. It means to include automobiles. Therefore, it is possible to display a necessary facility when it is necessary to replenish energy.

  Further, in this map information display device, the display facility information determination means determines to display not only the facility associated with the weighting variable but also the facility information of the same type of facility as the facility. it can. Therefore, even if there is no weighted facility itself on the map, it is possible to perform display that satisfies the user's request by displaying the facility with the alternative property.

  In the map information display device, the weighting variable can be identified for each user. Here, “identification for each user” means that, when two or more map information display devices are used, each user who uses the map information has a weighting variable. The weighting variable may be identified by a predetermined period. Here, “identified by a predetermined period” means having weighting variables divided into those that can be identified with respect to other periods such as time, day of the week, or season. Therefore, by setting the weighting variable more finely, it is possible to accurately grasp the user's request and display it appropriately.

  According to a second aspect of the present invention, a weighting variable correcting step of correcting a value of a weighting variable associated with the facility upon occurrence of a predetermined event related to the facility; and the weighting corrected by the weighting variable correcting step. A facility information display method comprising: a display facility information determination step for determining facility information to be displayed based on a variable; and a facility information display step for displaying the facility information determined by the display facility information determination step. .

  According to a third aspect of the present invention, there is provided a facility information display program that causes a calculation means to execute the facility information display method of the present invention.

FIG. 2 schematically shows information stored in the hard disk 19. The hard disk 19 is associated with (i) a program unit 30 in which a program executed by the CPU 11 is stored, (ii) a map information unit 41 in which map information is stored, and (iii) latitude and longitude point information. POI data part 42 in which facility information is stored, (iv) a search data part 43 in which facility information is associated so that the user can easily search, and (v) frequency of use of the facility of the user is recorded. A usage frequency counter unit 44, and (vi) a travel distance data unit 45 in which travel distance and the like are recorded.

  Here, the program unit 30 reads the map information from the map information unit 41 and the display POI control unit 31 that controls the display of the POI icon displayed on the display unit 22 together with the map information, as shown in FIG. The map information display unit 32 displayed on the display unit 22, the current position information acquisition unit 33 that acquires current position information from the GPS receiver 16, and the destination and waypoint set by the user using the remote controller 20 are used. And a navigation function unit 34 for searching for a route and displaying it together with map information or searching for a point where a designated facility is located.

  Further, the display POI control unit 31 determines the POI to be displayed on the map by using the usage frequency counter adding unit 35 for adding to the counter of the usage frequency counter unit 44, and displays the POI icon display unit 36 for displaying the POI icon. And a refueling travel distance management unit 37 that updates and manages the data of the travel distance data unit 45.

  Further, as shown in part of FIG. 4, the POI data unit 42 stores the names of facilities and icons representing the facilities corresponding to the points P1 to P6. Is present. Here, the same franchise chain is represented by the same facility name and the same icon.

  Further, as shown in FIG. 5, the search data unit 43 stores each facility represented by the POI data unit 42 for each category so that the user can easily search. For example, a family restaurant or fast food is assigned to the category of restaurant, and the family restaurant RA and family restaurant RB, which are franchise chains of the family restaurant, are further stored in the family restaurant category. Thereby, when the user desires to display the family restaurant RA, the family restaurant RA can be specified by sequentially selecting the restaurant category and the family restaurant category on the search screen. Furthermore, the POI of the family restaurant RA can be searched using the search function of the navigation function unit 34, and the icon of the family restaurant RA can be displayed on the map displayed on the display unit 22.

  Further, the usage frequency counter unit 44 is divided into total data 51 and breakdown data 52 as shown in FIG. The total data 51 stores the total number of times the facility has been used. Specifically, “use” refers to “when searching for a specific facility”, “when searching for a route designated as a destination or waypoint”, and “when parked at a point where the facility is located”. The breakdown data 52 stores the breakdown of the total data 51 divided into the person who uses the navigation system, the day of the week, and the time zone. Here, what is saved by day of the week and time is “when parked at a point where the facility is located”, “when searching for a specific facility” and “route search specified as a destination or waypoint” In the case of "If", the number of times is added to the column of no designation of day of the week. In this navigation device, the user is grasped by inputting the user type when the power is turned on, and the day of the week and the time are accurately acquired using a clock function (not shown) and the GPS receiver 16.

  Further, as shown in FIG. 7, the travel distance data unit 45 has an area for storing “average travel distance of one refueling” and “travel distance from the previous refueling”. Hereinafter, “average travel distance of one refueling” is simply referred to as “average travel distance”, and “travel distance from the previous refueling” is also simply referred to as “travel distance”.

  Next, a display method of the POI icon in the navigation device 10 configured as described above will be described.

  First, the user A turns on the navigation apparatus 10 and inputs the user A as the user type using the remote controller 20. When the navigation device 10 is turned on, the GPS receiver 16 acquires the radio wave of the GPS satellite and calculates the current position. Next, when the user instructs to search for the family restaurant RA using the remote controller 20, the CPU 11 executes the program of the navigation function unit 34 and uses the information in the POI data unit 42 to determine the vicinity of the current position. Search for family restaurant RA. On the other hand, the POI determination display unit 36 highlights and displays the POI icon of the searched family restaurant RA on the map displayed by the map information display unit 32, as shown in FIG. Here, the icon highlighted at the point P3 is the icon of the family restaurant RA, and the point PP is the current position.

  At this time, the usage frequency counter addition unit 35 detects that the facility has been searched in the processing of the usage frequency counter addition unit 35 shown in FIG. 9 (step S16), and performs the processing after step S12. In step S12, information on the user A, which is the user type, is acquired. Subsequently, in step S13, it is determined whether there is a record of the facility corresponding to the usage frequency counter unit 44. Here, since there is no record of the family restaurant RA that is the corresponding facility in the usage frequency counter unit 44 of FIG. 6, the process proceeds to step S14, and the record of the family restaurant RA is added. Next, in step S15, 1 is added to the number of times of family restaurant RA in the total data 51 of the usage frequency counter unit 44. In addition, in the breakdown data 52, 1 is added to each of the fields of the A user's day not specified in the record of the family restaurant RA. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  Next, when the user A uses the remote controller 20 to instruct a search for a route that uses the fast food FA at the point P2 in FIG. The program of the navigation function unit 34 of the program unit 30 is executed to search for a route, and a screen D2 that is a search result as shown in FIG.

  At this time, the usage frequency counter addition unit 35 detects that a route search has been performed in the processing of the usage frequency counter addition unit 35 shown in FIG. 9 (step S10). Next, in step S11, it is confirmed whether or not there is a POI at the destination or waypoint. If there is no POI, a negative determination is made, and the process ends. In this case, since the destination is the POI of the family restaurant RA and the waypoint is the POI of the fast food FA, a positive determination is made, and the process proceeds to step S12. In step S12, information on the user A, which is the user type, is acquired. In step S13, it is determined whether there is a facility corresponding to the usage frequency counter unit 44.

  Here, in the usage frequency counter unit 44 of FIG. 6, since there is a family restaurant RA as a corresponding facility, but there is no fast food FA record, the process proceeds to step S14, and a fast food FA record is added. Is done. Next, in step S15, 1 is added to the number of times of the family restaurant RA and the fast food FA in the total data 51 of the usage frequency counter unit 44. The breakdown data 52 is incremented by one for each of the records of the family restaurant RA and the fast food FA in the column where the user A does not specify the day of the week. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  Next, when the user A parks at the gas station GA at the point P1 in order to refuel on the way to the point P3 designated as the destination, in the processing of the use frequency counter adding unit 35 shown in FIG. A parking state is detected (step S17). When the usage frequency counter adding unit 35 detects the parking state, in step S18, it is confirmed whether or not there is a POI at the parking position. Here, when there is no POI at the parking position, a negative determination is made, and the processing is ended as it is. In this case, since there is a POI of the gas station GA, an affirmative determination is made, and the routine proceeds to step S19. In step S19, a parking position POI process that is a POI at the parking position is performed.

  In step S19, as shown in FIG. 13, it is first determined in step S21 whether the POI facility is a gas station (GS). In this case, since it is a gas station, an affirmative determination is made, and the process proceeds to step S22 which is a process of the refueling travel distance management unit 37. In step S22, the “travel distance from the previous refueling” of the travel distance data unit 45 is acquired, and the “average travel distance of one refueling” is recalculated to obtain “the average travel distance of one refueling”. To correct. Next, in step S23, “travel distance from the previous refueling” is reset.

  Here, whether or not the vehicle is parked is detected based on whether or not the engine of the automobile is stopped, and when the engine is started next time, the processing of the use frequency counter adding unit 35 of FIG. 9 is performed. Further, whether or not it is a gas station is determined by including facilities in the large category of the search data section 43 shown in FIG.

  Next, in step S24, the day of the week and time, Monday and 11:00 am are acquired. And the process of step S19 is complete | finished and it transfers to step S12 of FIG. In step S12, the type of user is acquired in the same manner as when the above route search is executed. Subsequently, in step S13, a negative determination is made in determining whether there is a record of the corresponding facility in the usage frequency counter unit 44. In step S14, a gas station GA record is added, and in step S15, One is added to the number of times of the gas station GA in the total data 51 of the usage frequency counter unit 44. In addition, in the breakdown data 52, 1 is added to the column of 6-12 o'clock Monday of the user A in the record of the gas station GA. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  The user A who has finished refueling departs from the point P1 where the gas station GA is located, and parks at the point P3 designated as the destination, not to the point P2 designated as the waypoint. As in the case of parking at the point P1, the usage frequency counter adding unit 35 detects the parking state in FIG. 9 (step S17), and in step S18, it is confirmed whether there is a POI at the parking position. In this case, since there is a POI of the family restaurant RA, an affirmative determination is made, and the process proceeds to step S19. In step S19, it is determined in step S21 in FIG. 13 whether or not the POI facility is a gas station. In this case, since it is not a gas station, a negative determination is made, the process proceeds to step S24, and the day of the week and time Monday and 11:00 am are acquired. Thereafter, the process of step S19 ends. The process proceeds to step S12 in FIG.

  Thereafter, in the same manner as when the vehicle is parked at the above-mentioned point P1, the current day of the week and time, Monday and 1 pm, are acquired, and in step S12, the information of the user A as the user type is acquired. Subsequently, a positive determination is made in determining whether or not there is a record of the corresponding facility in the usage frequency counter unit 44 in step S13. In step S15, the number of family restaurants RA in the total data 51 of the usage frequency counter unit 44 is determined. One is added. In addition, in the breakdown data 52, 1 is added to the record of Family Restaurant RA in the column of the user's Monday from 18:00 to 18:00. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  By performing the processing of the use frequency counter adding unit 35 as described above, the use frequency counter unit 44 is updated and used when the POI to be displayed by the POI determination display unit 36 is determined. A flowchart of the processing of the POI determination display unit 36 is shown in FIG. Hereinafter, a case where the user A is traveling in another place in the same car at 11:30 am on Monday of another week will be described as an example.

  The CPU 11 executes the program of the POI determination display unit 36, and as shown in FIG. 16, in step S31, the CPU 11 determines whether or not there is a facility designated for display by the user in advance. If the POI exists in the map displayed in the case of an affirmative determination, the POI icon is displayed on the map in step S32. Here, the POI to be displayed is not specified and is not displayed.

  Next, in step S33, it is determined whether or not the display range displayed on the display unit 22 by the map information display unit 32 has a POI in which the total data 51 of the usage frequency counter unit 44 is 5 times or more. . If an affirmative determination is made, the POI icon is displayed on the map in step S34. Here, since the number of times of the total data 51 of the family restaurant RB in the display range is 5, the icon of the family restaurant RB is displayed at the point P4 as shown in FIG.

  Returning to FIG. 16, the processing within 5 km is performed in step S35. In step S35, as shown in FIG. 17, first, in step S41, the "travel distance from the previous refueling" and the "average travel distance of one refueling" are acquired from the travel distance data unit 45. It is determined whether or not “travel distance from previous refueling” is within 5 km from “average travel distance of one refueling”. If an affirmative determination is made here, the process proceeds to step S42, and whether there is a POI of a gas station where the total data 51 of the usage frequency counter unit 44 is two or more times on the map displayed in step S42. Whether it is determined. If an affirmative determination is made in this determination, the POI icon is displayed on the map in step S44. If a negative determination is made, the process proceeds to step S43. Here, since there are no more than two gas stations in the usage frequency counter unit 44, the POI icon is not displayed, and the process proceeds to step S43. In step S43, it is determined whether there is a POI of the gas station on the map. If an affirmative determination is made, the POI icon is displayed on the map in step S45. In this case, since the gas station GB exists at the point P6 on the map, as shown in FIG. 18, the icon of the gas station GB is displayed at the point P5. Then, the process of step S35 is complete | finished. Then, the process proceeds to step S36 in FIG.

  In step S36, it is determined in the breakdown data 52 of the usage frequency counter unit 44 whether the POI of the facility that is used at least once on the same user, the same day of the week, and the same time zone is within the display range on the map. The Here, if a negative determination is made, the process ends. On the other hand, if a positive determination is made, the process proceeds to step S37.

  In step S37, it is determined whether or not the current time is after one hour before the corresponding time zone. Here, if a negative determination is made, the process ends. On the other hand, if a positive determination is made, the POI icon is displayed on the map in step S38. Here, the family restaurant RA is used once by a user A from 12:00 to 18:00 on Monday, and since this condition is met, the icon of the family restaurant RA is displayed. A state where the icon of the family restaurant RA is displayed at the point P6 is shown in FIG.

  As described above, in the present embodiment, the usage frequency counter addition unit 35 uses the usage frequency counter unit 44 for the searched facility, the facility that is the destination or waypoint in the route search, and the facility at the parked location. Add the number of times for the relevant facilities. As described above, using the added counter, the POI determination display unit 36 adds (a) the POI icon designated for display and (b) the usage frequency counter addition on the map displayed on the display unit 22. If the number of times of the part 35 is 5 times or more and (c) the traveling distance from the previous refueling is within 5 km to the average traveling distance of one refueling, the number of times of the usage frequency counter part 44 If there is more than two gas stations, or if there is no other gas station POI icon and (d) breakdown data 52 of the usage frequency counter unit 44, the number of times used for the same user, day of the week and time zone If there is a facility more than once, the POI icon of the corresponding facility is displayed when the user is on the day of the week and after one hour before that time zone.

  Therefore, according to this embodiment, since the icon of a facility is displayed based on an event relating to a user's preference and behavior such as a facility search, a route search, and a parking state detection, the user sets it specially. The facility information can be displayed on the map according to the user's preference and behavior.

  Moreover, according to this embodiment, since parking at a gas station is detected, a necessary facility can be displayed when refueling is necessary.

  In addition, according to the present embodiment, even when there is no gas station GA to be displayed on the map, since the gas station with alternatives is displayed, it is possible to perform display that satisfies the user's request.

  In addition, according to the present embodiment, since the total data 51 of the usage frequency counter unit 44 is identified by the user type, day of the week, and time zone, the user's request can be accurately grasped and displayed as appropriate. Can do.

Specifically, “use” refers to “when searching for a specific facility”, “when searching for a route designated as a destination or waypoint”, and “when parked at a point where the facility is located”. The breakdown data 52 stores the breakdown of the total data 51 divided into the person who uses the navigation system, the day of the week, and the time zone. Here, what is saved by day of the week and time is “when parked at a point where the facility is located”, “when searching for a specific facility” and “route search specified as a destination or waypoint” In the case of "If", the number of times is added to the column of no designation of day of the week. In this navigation device, the user is grasped by inputting the user type when the power is turned on, and the day of the week and the time are accurately acquired using a clock function (not shown) and the GPS receiver 16.

  Further, as shown in FIG. 7, the travel distance data unit 45 has an area for storing “average travel distance of one refueling” and “travel distance from the previous refueling”. Hereinafter, “average travel distance of one refueling” is simply referred to as “average travel distance”, and “travel distance from the previous refueling” is also simply referred to as “travel distance”.

  Next, a display method of the POI icon in the navigation device 10 configured as described above will be described.

  First, the user A turns on the navigation apparatus 10 and inputs the user A as the user type using the remote controller 20. When the navigation device 10 is turned on, the GPS receiver 16 acquires the radio wave of the GPS satellite and calculates the current position. Next, when the user instructs to search for the family restaurant RA using the remote controller 20, the CPU 11 executes the program of the navigation function unit 34 and uses the information in the POI data unit 42 to determine the vicinity of the current position. Search for family restaurant RA. On the other hand, the POI determination display unit 36 highlights and displays the POI icon of the searched family restaurant RA on the map displayed by the map information display unit 32, as shown in FIG. Here, the icon highlighted at the point P3 is the icon of the family restaurant RA, and the point PP is the current position.

  At this time, the usage frequency counter addition unit 35 detects that the facility has been searched in the processing of the usage frequency counter addition unit 35 shown in FIG. 9 (step S16), and performs the processing after step S12. In step S12, information on the user A, which is the user type, is acquired. Subsequently, in step S13, it is determined whether there is a record of the facility corresponding to the usage frequency counter unit 44. Here, since there is no record of the family restaurant RA that is the corresponding facility in the usage frequency counter unit 44 of FIG. 6, the process proceeds to step S14, and the record of the family restaurant RA is added. Next, in step S15, 1 is added to the number of times of family restaurant RA in the total data 51 of the usage frequency counter unit 44. In addition, in the breakdown data 52, 1 is added to each of the fields of the A user's day not specified in the record of the family restaurant RA. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  Next, when the user A uses the remote controller 20 to instruct a search for a route that uses the fast food FA at the point P2 in FIG. The program of the navigation function unit 34 of the program unit 30 is executed to search for a route, and a screen D2 that is a search result as shown in FIG.

  At this time, the usage frequency counter addition unit 35 detects that a route search has been performed in the processing of the usage frequency counter addition unit 35 shown in FIG. 9 (step S10). Next, in step S11, it is confirmed whether or not there is a POI at the destination or waypoint. If there is no POI, a negative determination is made, and the process ends. In this case, since the destination is the POI of the family restaurant RA and the waypoint is the POI of the fast food FA, a positive determination is made, and the process proceeds to step S12. In step S12, information on the user A, which is the user type, is acquired. In step S13, it is determined whether there is a facility corresponding to the usage frequency counter unit 44.

  Here, in the usage frequency counter unit 44 of FIG. 6, since there is a family restaurant RA as a corresponding facility, but there is no fast food FA record, the process proceeds to step S14, and a fast food FA record is added. Is done. Next, in step S15, 1 is added to the number of times of the family restaurant RA and the fast food FA in the total data 51 of the usage frequency counter unit 44. The breakdown data 52 is incremented by one for each of the records of the family restaurant RA and the fast food FA in the column where the user A does not specify the day of the week. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  Next, when the user A parks at the gas station GA at the point P1 in order to refuel on the way to the point P3 designated as the destination, in the processing of the use frequency counter adding unit 35 shown in FIG. A parking state is detected (step S17). When the usage frequency counter adding unit 35 detects the parking state, in step S18, it is confirmed whether or not there is a POI at the parking position. Here, when there is no POI at the parking position, a negative determination is made, and the processing is ended as it is. In this case, since there is a POI of the gas station GA, an affirmative determination is made, and the routine proceeds to step S19. In step S19, a parking position POI process that is a POI at the parking position is performed.

  In step S19, as shown in FIG. 13, it is first determined in step S21 whether the POI facility is a gas station (GS). In this case, since it is a gas station, an affirmative determination is made, and the process proceeds to step S22 which is a process of the refueling travel distance management unit 37. In step S22, the “travel distance from the previous refueling” of the travel distance data unit 45 is acquired, and the “average travel distance of one refueling” is recalculated to obtain “the average travel distance of one refueling”. To correct. Next, in step S23, “travel distance from the previous refueling” is reset.

  Here, whether or not the vehicle is parked is detected based on whether or not the engine of the automobile is stopped, and when the engine is started next time, the processing of the use frequency counter adding unit 35 of FIG. 9 is performed. Further, whether or not it is a gas station is determined by including facilities in the large category of the search data section 43 shown in FIG.

  Next, in step S24, the day of the week and time, Monday and 11:00 am are acquired. And the process of step S19 is complete | finished and it transfers to step S12 of FIG. In step S12, the type of user is acquired in the same manner as when the above route search is executed. Subsequently, in step S13, a negative determination is made in determining whether there is a record of the corresponding facility in the usage frequency counter unit 44. In step S14, a gas station GA record is added, and in step S15, One is added to the number of times of the gas station GA in the total data 51 of the usage frequency counter unit 44. In addition, in the breakdown data 52, 1 is added to the column of 6-12 o'clock Monday of the user A in the record of the gas station GA. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  The user A who has finished refueling departs from the point P1 where the gas station GA is located, and parks at the point P3 designated as the destination, not to the point P2 designated as the waypoint. As in the case of parking at the point P1, the usage frequency counter adding unit 35 detects the parking state in FIG. 9 (step S17), and in step S18, it is confirmed whether there is a POI at the parking position. In this case, since there is a POI of the family restaurant RA, an affirmative determination is made, and the process proceeds to step S19. In step S19, it is determined in step S21 in FIG. 13 whether or not the POI facility is a gas station. In this case, since it is not a gas station, a negative determination is made, the process proceeds to step S24, and the day of the week and time Monday and 11:00 am are acquired. Then, the process of step S19 is complete | finished. The process proceeds to step S12 in FIG.

  Thereafter, in the same manner as when the vehicle is parked at the above-mentioned point P1, the current day of the week and time, Monday and 1 pm, are acquired, and in step S12, the information of the user A that is the user type is acquired. Subsequently, a positive determination is made in determining whether or not there is a record of the corresponding facility in the usage frequency counter unit 44 in step S13. In step S15, the number of family restaurants RA in the total data 51 of the usage frequency counter unit 44 is determined. One is added. In addition, in the breakdown data 52, 1 is added to the record of Family Restaurant RA in the column of the user's Monday from 18:00 to 18:00. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the parts of the breakdown data 52 that are not changed are omitted.

  By performing the processing of the use frequency counter adding unit 35 as described above, the use frequency counter unit 44 is updated and used when the POI to be displayed by the POI determination display unit 36 is determined. A flowchart of the processing of the POI determination display unit 36 is shown in FIG. Hereinafter, a case where the user A is traveling in another place in the same car at 11:30 am on Monday of another week will be described as an example.

  The CPU 11 executes the program of the POI determination display unit 36, and as shown in FIG. 16, in step S31, the CPU 11 determines whether or not there is a facility designated for display by the user in advance. If the POI exists in the map displayed in the case of an affirmative determination, the POI icon is displayed on the map in step S32. Here, the POI to be displayed is not specified and is not displayed.

  Next, in step S33, it is determined whether or not the display range displayed on the display unit 22 by the map information display unit 32 has a POI in which the total data 51 of the usage frequency counter unit 44 is 5 times or more. . If an affirmative determination is made, the POI icon is displayed on the map in step S34. Here, since the number of times of the total data 51 of the family restaurant RB in the display range is 5, the icon of the family restaurant RB is displayed at the point P4 as shown in FIG.

  Returning to FIG. 16, the processing within 5 km is performed in step S35. In step S35, as shown in FIG. 17, first, in step S41, the "travel distance from the previous refueling" and the "average travel distance of one refueling" are acquired from the travel distance data unit 45. It is determined whether or not “travel distance from previous refueling” is within 5 km from “average travel distance of one refueling”. If an affirmative determination is made here, the process proceeds to step S42, and whether there is a POI of a gas station where the total data 51 of the usage frequency counter unit 44 is two or more times on the map displayed in step S42. Whether it is determined. If an affirmative determination is made in this determination, the POI icon is displayed on the map in step S44. If a negative determination is made, the process proceeds to step S43. Here, since there are no more than two gas stations in the usage frequency counter unit 44, the POI icon is not displayed, and the process proceeds to step S43. In step S43, it is determined whether there is a POI of the gas station on the map. If an affirmative determination is made, the POI icon is displayed on the map in step S45. In this case, since the gas station GB exists at the point P6 on the map, as shown in FIG. 18, the icon of the gas station GB is displayed at the point P5. Then, the process of step S35 is complete | finished. Then, the process proceeds to step S36 in FIG.

  In step S36, it is determined in the breakdown data 52 of the usage frequency counter unit 44 whether the POI of the facility that is used at least once on the same user, the same day of the week, and the same time zone is within the display range on the map. The Here, if a negative determination is made, the process ends. On the other hand, if a positive determination is made, the process proceeds to step S37.

  In step S37, it is determined whether or not the current time is after one hour before the corresponding time zone. Here, if a negative determination is made, the process ends. On the other hand, if a positive determination is made, the POI icon is displayed on the map in step S38. Here, the family restaurant RA is used once by a user A from 12:00 to 18:00 on Monday, and since this condition is met, the icon of the family restaurant RA is displayed. A state where the icon of the family restaurant RA is displayed at the point P6 is shown in FIG.

  As described above, in the present embodiment, the usage frequency counter addition unit 35 uses the usage frequency counter unit 44 for the searched facility, the facility that is the destination or waypoint in the route search, and the facility at the parked location.
