Description

Specification

Map information display device, facility information display method, facility information display program, and recording medium

Technical field

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 and facility information display method for displaying facility information on a map. The present invention relates to a facility information display program and a recording medium thereof. Background art

[0002] In recent years, in a map information display device equipped with a liquid crystal display device or the like for displaying a map, which is installed in an automobile or the like, its position is calculated by GPS (Global Positioning System).

Navigation devices that display a route to a destination just by displaying their own location and provide route guidance are widely used. Such a navigation device holds information on nearby facilities associated with points on the map called POI (Point of Interest).

By overlaying the information contained in the POI with the map information on the screen, more information can be provided to the driver.

[0003] Generally, this POI information is displayed on a map by a small image called an icon. Therefore, especially when a map is displayed in an urban area, there are many facilities at a nearby point, and 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 an original function of the device. A method has been proposed to hide the icons other than the POI icon, which is a sign for road guidance when approaching a corner or other corner that is the point of road guidance in response to such a situation! Speak (see Patent Document 1).

[0004] Patent Document 1: Patent Publication No. 2004-85466

Disclosure of the invention

Problems to be solved by the invention [0005] The conventional technology described above is excellent in smoothly performing route guidance, which is an original function of the navigation device. However, even if the navigation function is not executed, displaying many POI icons makes it difficult to check the map information due to the display of icons unnecessary for the user. Since a lot of image information processing is required, the burden on the CPU (Central Processing Unit) is large, and the speed until rendering is often slow!

[0006] In addition, a method of displaying only the POI icon set by the user is also performed. The power of the POI icon to be displayed every time the user's preference changes is changed. It is not an easy-to-use function.

[0007] The present invention has been made in view of the above circumstances, and is capable of appropriately displaying POI facility information in accordance with the user's preference and behavior that is not set by the user. An object is to provide a display device, a facility information display method, a facility information display program, and a recording medium thereof.

Means for solving the problem

[0008] According to a first aspect of the present invention, there is provided 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; Display facility information determining means for determining facility information to be displayed together with the displayed map; and facility information display means for displaying the facility information determined by the display facility information determining means together with the map; This is a map information display device.

[0009] Here, a "predetermined event related to a facility" is specifically an event related to a facility, such as staying at a place where the facility is located or searching for the facility, and is predetermined. Means. 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. Good. “Based on weighting variable” means that the weighting variable is treated as one requirement in the process of determining the facility information to be displayed. In addition, “facility information” means information about the facility, specifically the location information of the facility and the image information of the icon. OI (Point Of Interest

Information power that can be acquired.

[0010] Therefore, by displaying the facility information based on the occurrence of a predetermined event and! /, Experience, the user's preference and behavior can be adjusted on a map that is not set by the user. Facility information can be displayed.

[0011] In this map information display device, one of the predetermined events is a search for the facility.

, And can be. Here, “facility search” means a search for a specific facility by a function provided in the map information display device. Therefore, the facilities that the user is interested in can be reflected in the display by weighting them.

[0012] 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 current position information acquired by the current position information acquisition means. It can be said that it is a stay. Here, "Current position information acquisition means

"Includes methods based on the calculation of location information using GPS satellites and other methods of acquiring current location information. Therefore, it is possible to reflect on the display by attaching importance to the facility where the user stops.

[0013] 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 destination. And designation of the waypoint. Therefore, it is possible to reflect on the display by weighting the facilities set as the waypoints and destinations by the user.

[0014] Further, in this map information display device, the facility information 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 is performed, and the facility information When it is determined that the supplement is necessary, the display means may display the facility information for the supplement. Here, “transportation means that requires replenishment of energy” is generally a vehicle that uses gasoline as fuel, and other travel means that require supplementation of energy, such as charging. It also includes electric vehicles and so on. Therefore, the necessary facilities can be displayed when energy needs to be replenished. [0015] Further, in this map information display device, the display facility information determining means determines to display facility information of the same type of facility as that facility other than just the facility associated with the weighting variable. can do. Therefore, even if there is no weighted facility itself on the map, it is possible to display that satisfies the user's request by displaying the facility with the alternative property.

[0016] 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 display device 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 for other periods such as time, day of the week, or season. Therefore, by setting the weighting variables more carefully, it is possible to accurately grasp the user's request and display it appropriately.

[0017] According to the 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; A display facility information determination step for determining facility information to be displayed based on the weighted variables !; a facility information display step for displaying the facility information determined by the display facility information determination step; Is a facility information display method.

FIG. 2 schematically shows information stored in the hard disk 19. The hard disk 19 includes (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) point information on latitude and longitude. The POI data part 42 in which information on the associated facilities is stored, (iv) the search data part 43 associated with the facility information so that the user can easily search the facility information, and (V) the user's information A usage frequency counter unit 44 that records the frequency of use of the facility; and (vi) a travel distance data unit 45 that records a travel distance and the like.

Here, as shown in FIG. 3, the program unit 30 includes a display POI control unit 31 that controls display of a POI icon displayed together with the map information on the display unit 22, and the map information as a map information unit. 41, a map information display unit 32 that reads from 41 and displays it on the display unit 22, a current location information acquisition unit 33 that acquires current location information from the GPS receiver 16, and a destination and a destination set by the user using the remote controller 20. It has a navigation function unit 34 that searches for a route using a transit point, displays it with map information, and searches for a point where a designated facility is located. [0025] Further, the display POI control unit 31 determines the POI to be displayed on the map by using the usage frequency counter addition unit 35 for adding to the counter of the usage frequency counter unit 44, and POI determination for displaying the icon of the POI A display unit 36 and a refueling mileage management unit 37 that updates and manages data in the mileage data unit 45 are provided.

[0026] Further, as shown in part of FIG. 4, the POI data section 42 stores the names of the facilities and icons representing the facilities corresponding to the points P1 to P6. This means that each facility exists. Here, the same franchise chain is represented by the same facility name and the same icon.

In addition, as shown in FIG. 5, the search data section 43 stores the facilities represented by the POI data section 42 for each category so that the user can easily search. For example, family restaurants and fast food are allocated to the restaurant category, and the family restaurant RA and family restaurant RB, which are franchise chains of family restaurants, are 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 selecting the restaurant category and the family restaurant category in order 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.

In addition, 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 route”, and “when parking at a point where the facility is located”. The Further, the breakdown data 52 stores the breakdown of the total data 51 by being 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 “designated as a destination or waypoint” In the case of “route search”, the number of times is added to the “day not specified” column. 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 time are not shown. Accurately acquired using clock function and 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 mileage of one refueling” is also simply referred to as “average mileage”, and “travel distance from the previous refueling” is also simply referred to as “travel distance”.

[0030] Next, a method for displaying a POI icon in the navigation device 10 configured as described above will be described.

[0031] First, the user A turns on the navigation device 10 and inputs the user A as the user type for IJ using the remote controller 20. When the navigation device 10 is turned on, the GPS receiver 16 acquires GPS satellite radio waves and calculates the current position. Next, when the user power remote control 20 is used to instruct the search for the family restaurant RA, the CPU 11 executes the program of the navigation function unit 34 and uses the information in the POI data unit 42 to find 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 adding unit 35 detects that the facility has been searched in the processing of the usage frequency counter adding unit 35 shown in FIG. 9 (step S 16), and after step S 12. Perform the process. In step S12, information on user A, which is a user type, is obtained. Subsequently, in step S13, it is determined whether there is a record of the facility corresponding to the use 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 family restaurants RA in the total data 51 of the usage frequency counter unit 44. In addition, in the breakdown data 52, 1 is added to the record of the family restaurant RA in the column of A user's day not specified. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, of the breakdown data 52, the change The missing part is omitted.

[0033] Next, user A uses remote control 20 to instruct the search for a route from fast food FA at point P2 in FIG. 8 to the destination at family restaurant RA at point P3. Then, the CPU 11 executes the program of the navigation function unit 34 of the program unit 30 to search for a route, and displays the screen D2 as a search result on the display unit 22 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 S 10). Next, in step S11, it is confirmed whether or not a POI exists at the destination or waypoint. If the POI is present, a negative determination is made, and the process ends. In this case, the POI of the family restaurant RA is at the destination and the POI of the fast food FA is at the waypoint, so a positive determination is made and the process proceeds to step S12. In step S12, information on 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.

[0035] Here, in the usage frequency counter unit 44 of FIG. 6, there is a family restaurant RA as a corresponding facility, but there is no fast food FA record. A record is added. Next, in step S15, 1 is added to the number of family restaurants RA and fast food FA 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 records of Family Restaurant RA and Fast Food F A in the column where A user 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.

[0036] Next, if you park at the gas station GA at the point P1 to refuel on the way to the point P3 designated as the destination of user A, the usage frequency counter calorie calculation unit 35 shown in FIG. In the process, the parking state is detected (step S17). When the usage frequency counter calorie calculation unit 35 detects the parking state, in step S18, it is confirmed whether or not the POI is at the parking position. Here, if there is no POI at the parking position, a negative determination is made, and the process ends. In this case, there is a POI of the gas station GA Therefore, a positive determination is made, and the routine goes to Step S19. In step S19, a parking position POI process that is a POI at the parking position is performed.

[0037] In step S19, as shown in FIG. 13, first, in step S21, it is determined whether or not the POI facility is a gas station (GS) force. In this case, since it is a gas station, an affirmative determination is made, and the routine proceeds to step S22 which is processing of the refueling mileage management unit 37. In step S22, the “mileage from the previous refueling” in the mileage data section 45 is acquired, and the “average mileage of one refueling” is recalculated, and the “average mileage of one refueling” is calculated. To correct. Next, in step S23, “travel distance from 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 in FIG. 9 is performed. Whether or not the station is a gas station is determined by including the facilities in the large category of the search data section 43 shown in FIG.

[0039] Next, in step S24, the day of the week and time, Monday and 11:00 am are acquired. Then, the process of step S19 ends, and the process proceeds 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 or not 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, 1 is added to the number of gas stations GA in the total data 51 of the usage frequency counter section 44. In addition, in the breakdown data 52, 1 is added to the column of 6-12 o'clock on the Monday of user A in the gas station GA record. The state of the usage frequency counter unit 44 after the addition is shown in FIG. In this figure, the unmodified part of the breakdown data 52 is omitted.

[0040] User A, who has finished refueling, departs from point P1 where the gas station GA is located, and parks at the point P3 designated as the destination, not 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, determines whether or not the parking position has POI. It is confirmed. In this case, since the POI of the family restaurant RA exists, a positive determination is made, and the process proceeds to step S19. In step S19, the ability to determine whether the POI facility is a gas station in step S21 in FIG. 13 In this case, since it is not a gas station, a negative determination is made, the process proceeds to step S 24, and the day of the week is determined. And the hours Monday and 11:00 am. Thereafter, the process of step S19 ends. The process proceeds to step S12 in FIG.

[0041] Thereafter, in the same manner as when the vehicle is parked at the above-mentioned point P1, the day of the week and the time, the Monday and 1:00 pm, are obtained, and in step S12, the information of the user A as the user type is obtained. get. 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 of the total data 51 in the usage frequency counter unit 44 1 is added to. In addition, in the breakdown data 52, 1 is added to the record of Family Restaurant RA in the column of 12:00 to 18:00 on Monday of user A. 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.

[0042] By performing the processing of the usage frequency counter adding unit 35 as described above, the usage 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. The following describes an example where User A is driving in the same car at another location at 11:30 am on another Monday.

[0043] The CPU 11 executes the program of the POI determination display unit 36, and as shown in FIG. 16, in step S31, it is determined whether there is a facility that has been designated by the user. To do. 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.

[0044] Next, in step S33, whether or not the display range displayed on the display unit 22 by the map information display unit 32 includes a POI with the total data 51 of the usage frequency counter unit 44 being 5 or more times. Determined. Here, if a positive determination is made, step S34 is performed. The POI icon is displayed on the map. Here, since the total number of times of the total data 51 of the family-one 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 subsequently 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 calculated from the travel distance data section 45. Acquired and judge whether the “travel distance from the previous refueling” is within 5 km from the “average travel distance of one refueling”. If an affirmative determination is made here, the process proceeds to step S42, and the POI of the gas station where the total data 51 of the usage frequency counter unit 44 is two or more times is displayed on the map displayed in step S42. It is determined whether it exists. If a positive 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 for the gas station on the map. Here, if a positive 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, the icon of the gas station GB is displayed at the point P5 as shown in FIG. Thereafter, the process of step S35 ends. Then, the process proceeds to step S36 in FIG.

[0046] In step S36, 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. Is determined. 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.

[0047] 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, Family Restaurant RA Power User A will run from 12:00 to 18:00 on Monday Since it is used once and this condition is met, the family restaurant RA icon is displayed. Fig. 18 shows the icon of the family restaurant RA displayed at point P6.

[0048] As described above, in the present embodiment, the use frequency counter adding unit 35 uses the facilities found at the destination, the facilities determined as the destination or waypoint in the route search, and the facilities at the parked location. The frequency counter 44 adds the number of times for the relevant facility. Thus, using the added counter, the POI determination display unit 36 displays (a) the POI icon designated for display on the map displayed on the display unit 22 and (b) the usage frequency counter addition. If the frequency of part 35 is 5 times or more and (c) the distance traveled from the previous refueling is less than 5 km to the average travel distance of one refueling, the usage frequency counter 44 Use for the same user, day of the week, and time of day at the gas station more than 2 times, or in other cases, the POI icon of other gas stations and (d) Breakdown data 52 of the usage frequency counter 44 If there is a facility that has been used more than once, the POI icon of the corresponding facility will be displayed when the user and day of the week are one hour before that time zone.

Therefore, according to the present embodiment, the facility icon is displayed based on events related to facility search, route search and parking state detection, and user preferences and behaviors! /! Therefore, it is possible to display facility information that matches the user's preference and behavior on a map that is not specially set by the user.

[0050] Further, according to the present embodiment, since parking at a gas station is detected, it is possible to display necessary facilities when refueling is necessary.

[0051] Further, 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. it can.

[0052] Further, according to the present embodiment, since the total data 51 of the usage frequency counter unit 44 is identified by the type, day of the week, and time zone of the user, the user's request is accurately grasped and appropriately Can be displayed.

<Modification of Embodiment> The present invention is not limited to the above embodiment, and various modifications are possible.

For example, in the present embodiment, as a weighting variable, the number of times an event has occurred is recorded, and a flag that is determined based on the presence / absence of a power that is determined based on whether or not a predetermined number of times has been exceeded. Depending on the variable, the display judgment may be performed by another method, or the display judgment may be performed by weighting by another method such as changing the weighting method according to the type of facility.

[0055] In the present embodiment, the ability to use facility search, route search, and parking state detection as predetermined events may be other events.

[0056] Further, according to the present embodiment, information on parking with the engine stopped is detected as a state of staying! /, But it is determined based on other times when the engine is stopped. It is good.

In this embodiment, the determination that refueling is necessary is performed by comparing the “travel distance from the previous refueling” and the “average travel distance of one refueling”. It may be obtained by other methods such as direct acquisition.
