The exclusion processing unit 108 newly excludes facilities for which route guidance cannot be performed due to lack of information for specifying the location of the facility or because the information for specifying the location of the facility is not valid. Set as target. The exclusion cancellation processing unit 109 cancels the exclusion of the facilities that are excluded by the exclusion processing unit 108.

  The functional units of the arithmetic processing unit 1 described above, that is, the main control unit 101, the input reception unit 102, the output processing unit 103, the route search unit 104, the route guidance unit 105, the facility search unit 106, the search result output unit 107, The exclusion processing unit 108 and the exclusion cancellation processing unit 109 are constructed by the CPU 21 reading and executing a predetermined program. Therefore, the RAM 21 stores a program for realizing the processing of each functional unit.

  In addition, in order to make an understanding of the structure of the navigation apparatus 100 easy, each above-mentioned component is classified according to the main processing content. Therefore, the present invention is not limited by the way of classifying the components and their names. The configuration of the navigation device 100 can be classified into more components depending on the processing content. Moreover, it can also classify | categorize so that one component may perform more processes. Each functional unit may be constructed by hardware (ASIC, GPU, etc.). Further, the processing of each functional unit may be executed by one hardware or may be executed by a plurality of hardware.

  [Description of Operation] Next, the operation of the navigation device 100 will be described. FIG. 5 is a flowchart of a search exclusion process in which the navigation device 100 performs a facility search in accordance with a user instruction, and excludes and displays a facility to be excluded from the result. This flow starts when the user is requested to search for a facility that satisfies the condition via the input receiving unit 102.

  First, the facility search unit 106 searches for facilities that meet the conditions (step S001). Specifically, the facility search unit 106 searches for facilities that match the conditions received via the input reception unit 102, and lists candidate facilities.

  Next, the search result output unit 107 excludes the excluded facility from the search result and displays it (step S002). Specifically, the search result output unit 107 specifies a facility included in the facility ID 251 of the display exclusion facility table 250 among the facilities obtained as a result of searching in step S001. When the search result output unit 107 determines that the current time is included in the period specified by the specified exclusion start period 252 and exclusion end period 253, the search result output unit 107 Remove the facility from the list. The search result output unit 107 transfers the list to the output processing unit 103, and the output processing unit 103 displays the transferred list.

  Next, the exclusion processing unit 108 receives a facility designation from the user (step S003). Specifically, the exclusion processing unit 108 receives an input for selecting one facility from the facility list displayed in step S002 from the user via the input receiving unit 102. Here, the purpose of the user selecting the facility is, for example, specifying as a destination or confirming detailed location information.

  Next, the exclusion processing unit 108 determines whether a valid latitude / longitude is set for the facility that has received the designation (step S004). Specifically, the exclusion processing unit 108 specifies the facility specified by the designation received in step S003, and searches for information on the latitude and longitude of the facility. Then, the exclusion processing unit 108 determines whether the latitude / longitude information is missing or indicates a latitude / longitude that does not actually exist. In addition, when the information of the latitude / longitude of the facility is not missing and the actual latitude / longitude is present, it can be said that a valid latitude / longitude is set for the facility. When a valid latitude / longitude is set (“No” in step S004), the exclusion processing unit 108 designates the facility that has received the designation in step S003, ends the process, and performs a predetermined process ( For example, a route search using the facility as a destination is performed.

  If a valid latitude / longitude has not been set (“Yes” in step S004), the exclusion processing unit 108 determines whether or not to set the facility whose designation is accepted in step S003 as an excluded facility. An inquiry and a response from the user are accepted (step S005). Specifically, when a valid latitude / longitude is not set, the exclusion processing unit 108 displays a pop-up display for inquiring whether or not to set the facility whose designation is accepted in step S003 as the facility to be excluded. And accepts an input of selection about whether or not to exclude. When an input indicating that the facility is not an excluded facility is received (“No” in step S005), the exclusion processing unit 108 specifies the facility received in step S003, ends the processing, and performs predetermined processing (for example, Perform route search etc. with the facility as the destination.

  When an input indicating that the facility is to be excluded is accepted (“Yes” in step S005), the exclusion processing unit 108 accepts designation of an end period of the period in which the facility that has accepted designation in step S003 is excluded ( Step S006). Specifically, the exclusion processing unit 108 accepts designation of the end period by displaying a screen for accepting designation of the end period of the period for excluding the facility whose designation has been received in step S003. It should be noted that the exclusion processing unit 108 can accept the designation that the end period of the period to be excluded is not designated.

  When designation of the end period of the period to be excluded is received (“Yes” in step S006), the exclusion processing unit 108 excludes the facility that has received the designation in step S003 until the end period in which the designation is accepted. It is set as a thing (step S007). Specifically, the exclusion processing unit 108 adds the facility ID of the facility that has been designated in step S003 to the facility ID 251 of the display exclusion facility table 250, and stores the current time in the exclusion start period 252 of the added facility. In the exclusion end period 253, the end period in which the designation is accepted is stored. Then, the exclusion processing unit 108 returns the process to step S002.

  When the designation not specifying the end period of the period to be excluded is received (“No” in step S006), the exclusion processing unit 108 excludes the facility that has received the designation in step S003 indefinitely. It sets as a thing (step S008). Specifically, the exclusion processing unit 108 adds the facility ID of the facility that has been designated in step S003 to the facility ID 251 of the display exclusion facility table 250, and stores the current time in the exclusion start period 252 of the added facility. In the exclusion end period 253, information indicating that the period is indefinite is stored. Then, the exclusion processing unit 108 returns the process to step S002.

  The above is the processing content of the search exclusion process. By performing the above search exclusion process, the navigation apparatus 100 can exclude and display the facilities set as exclusion targets when displaying the corresponding facilities as a result of the search. In addition, when the facility designated from the displayed search result does not have valid position information, the navigation apparatus 100 can set and exclude the facility as a facility to be excluded from the future.

  Next, examples of screens displayed by the search exclusion process are shown in FIGS. 6 (a) and 6 (b). FIG. 6A is a diagram illustrating an example of a screen 300 displayed in step S002 of the search exclusion process. The screen 300 includes a search condition display area 310 that displays information for specifying a search condition, and a search result display area 320 that indicates a search result. In the search result display area 320, facilities corresponding to the search conditions as a result of performing the facility search in step S001 are displayed. In the search result display area 320, facilities already set as exclusion targets are not displayed. In addition, when each displayed facility is selected and input by, for example, touch input or the like, if the location information of the facility is valid, a map screen or the like is displayed to indicate the location. A screen 350 shown in FIG. 6B is an example of a pop-up screen displayed in step S005 of the search exclusion process.

  The screen 350 includes a message that the selected facility cannot be displayed because it does not have valid location information, and a message that inquires whether to set the facility to be excluded from the search target thereafter. It has a message display area 360 to be displayed, a “Yes” button display area 371 for accepting a response input to the message, and a “No” button display area 372. The “Yes” button display area 371 accepts an input to answer the inquiry in the message display area 360 affirmatively, and the “No” button display area 372 indicates to answer the inquiry in the message display area 360 negatively. Accept input.

  FIG. 7 is a flowchart of an arrival exclusion process for receiving a route guidance according to a recommended route and setting so as to exclude the facility designated as the destination after arriving at the destination. For example, the process is set as an exclusion target when the destination store is closed when the facility designated as the destination is reached. This flow is started when the route guiding unit 105 detects that the destination has been reached. The process may be started when the user requests to set the destination as an excluded facility via the input receiving unit 102.

  First, the exclusion processing unit 108 inquires of the user whether or not a facility set as a destination is an excluded facility (step S101). Specifically, the exclusion processing unit 108 displays a screen for inquiring the user whether or not the facility set as the destination is an excluded facility by pop-up display or the like, and accepts an input from the user. If an input indicating that the destination is not an excluded facility is received (“No” in step S101), the exclusion processing unit 108 ends the arrival exclusion process.

  When an input indicating that the destination is an excluded facility is received (“Yes” in step S101), the exclusion processing unit 108 receives designation of an end period of a period for excluding the facility set as the destination ( Step S102). Specifically, the exclusion processing unit 108 displays a screen or the like for accepting designation of the end period of the period for excluding the facility set as the destination, and accepts designation of the end period. It should be noted that the exclusion processing unit 108 can accept the designation that the end period of the period to be excluded is not designated.

  When designation of the end period of the period to be excluded is received (“Yes” in step S102), the exclusion processing unit 108 selects the facility set as the destination until the end period of receiving the designation. As long as it is excluded, it is set (step S103). Specifically, the exclusion processing unit 108 adds the facility ID of the facility set as the destination to the facility ID 251 of the display exclusion facility table 250, and receives the designation in the exclusion end period 253 of the added facility. Stores the end period. And the exclusion process part 108 advances a process to step S005.

  When an input indicating that the end period of the period to be excluded is not specified is received (“No” in step S102), the exclusion processing unit 108 excludes the facility set as the destination indefinitely. It sets as what to do (step S104). Specifically, the exclusion processing unit 108 adds the facility ID of the facility set as the destination to the facility ID 251 of the display exclusion facility table 250, and has no expiration date in the exclusion end period 253 of the added facility. Stores information to that effect. And the exclusion process part 108 advances a process to step S105.

  Next, the exclusion processing unit 108 accepts designation of the start period of the period for excluding the facility set as the destination (step S105). Specifically, the exclusion processing unit 108 receives a designation of the start period by displaying a screen for accepting designation of the start period of the period for excluding the facility set as the destination. It should be noted that the exclusion processing unit 108 can accept the designation that the start period of the period to be excluded is not designated.

  When the designation of the start period of the period to be excluded is received (“Yes” in step S105), the exclusion processing unit 108 excludes the facility set as the destination from the start period when the designation is accepted (Step S106). Specifically, for the facility added to the facility ID 251 in the display exclusion facility table 250 in step S103 or step S104, the exclusion processing unit 108 starts accepting designation in the added facility exclusion start period 252 Stores the period. Then, the exclusion processing unit 108 ends the arrival exclusion process.

  When the designation indicating that the start period of the period to be excluded is not designated is received (“No” in step S105), the exclusion processing unit 108 immediately excludes the facility set as the destination. It sets as a thing (step S107). Specifically, the exclusion processing unit 108 indicates that the facility added to the facility ID 251 of the display exclusion facility table 250 in step S103 or step S104 is immediately in the added facility exclusion start period 252. Stores information, for example, the time of processing. Then, the exclusion processing unit 108 ends the arrival exclusion process.

  The above is the processing content of the arrival exclusion process. By performing the arrival exclusion process, the navigation device 100 subsequently excludes the facilities that arrived at the destination but failed to achieve the purpose from the search target when displaying the corresponding facility as a result of the search. Can be displayed.

  Further, since the start period for excluding the facility can be specified in step S106, for example, when it is known that the facility is closed on a predetermined day, the facility is closed at the start period to be excluded. By setting the date of the day, it is possible to avoid searching for the facility after the store is closed.

  Next, an example of a screen displayed by the arrival exclusion process is shown in FIG. FIG. 8 is a diagram showing an example of a screen 400 displayed in step S101 of the arrival exclusion process. The screen 400 includes an operation menu display area 410 that displays information for receiving an operation instruction for the navigation device 100, and a pop-up display area 420 that inquires whether or not to exclude the destination from the search target. In the pop-up display area 420, a message display area 421 for displaying a message asking whether to set the facility designated as the destination to be excluded from the search target thereafter, and a response input to the message are accepted. ”Button display area 422 and“ No ”button display area 423. The “Yes” button display area 422 accepts an input to answer the inquiry in the message display area 421 positively, and the “No” button display area 423 indicates to answer the inquiry in the message display area 421 negatively. Accept input.

  FIG. 9 is a flowchart of an exclusion cancellation process for canceling the exclusion of a facility set as an exclusion target. For example, this is a process for making a facility excluded in the past by a search exclusion process or an arrival exclusion process a search target again. This flow is started when a request is received from the user via the input receiving unit 102 to cancel the exclusion of a predetermined facility.

  First, the exclusion cancellation processing unit 109 displays facilities set as exclusion targets (step S201). Specifically, the exclusion cancellation processing unit 109 displays a screen for accepting selection of facilities to be excluded from the facilities set as exclusion targets.

  Next, the exclusion cancellation processing unit 109 receives an input for designating a facility to be excluded from the facilities displayed in step S201 (step S202). Specifically, the exclusion cancellation processing unit 109 receives an input for selecting a facility whose cancellation is to be excluded from the user via the input reception unit 102.

  Next, the exclusion cancellation processing unit 109 displays a screen for accepting designation of the exclusion end period for the facility whose selection has been accepted in step S202, and accepts the presence or absence of designation of the end period (step S203). It should be noted that the exclusion cancellation processing unit 109 can accept the designation that the end period of the period to be excluded is not designated.

  When the designation of the end period of the period to be excluded is received (“Yes” in step S203), the exclusion cancellation processing unit 109 excludes the facility that has received the designation in step S202 until the end period in which the designation is accepted. It sets as what to do (step S204). Specifically, the exclusion cancellation processing unit 109 identifies the facility ID of the facility that has received the designation in step S202 from the facility ID 251 of the display exclusion facility table 250, and designates the designation in the exclusion end period 253 of the identified facility. Stores the accepted end period. Then, the exclusion cancellation processing unit 109 ends the exclusion cancellation processing.

  When the designation not specifying the end period of the period to be excluded is received (“No” in step S203), the exclusion cancellation processing unit 109 immediately excludes the facility that has received the designation in step S202. It is set to be canceled (step S205). Specifically, the exclusion cancellation processing unit 109 identifies the facility ID of the facility that has received the designation in step S202 from the facility ID 251 of the display exclusion facility table 250, and immediately, at the exclusion end period 253 of the identified facility. Information indicating that it is present, for example, the current time at the time of processing is stored. Then, the exclusion cancellation processing unit 109 ends the exclusion cancellation processing.

  The above is the processing content of the exclusion cancellation processing. By performing the exclusion release process, the navigation device 100 can display the facilities that have no reason to be excluded without excluding them when displaying the corresponding facilities as a result of the search.

  The embodiment of the present invention has been described above. According to one embodiment of the present invention, the navigation apparatus 100 can exclude a facility that the user wants to exclude from the destination or search target in the facility search process without updating the facility information.

  As a regular maintenance process, the exclusion cancellation processing unit 109 deletes, from the display exclusion facility table 250, the facility to be excluded whose exclusion period has ended (that is, the facility that is displayed because it is no longer an exclusion target). It may be. Specifically, the exclusion cancellation processing unit 109 determines, for each facility ID 251 stored in the display exclusion facility table 250, whether or not the date and time stored in the exclusion end period 253 is older than the processing time point. In this case, the record corresponding to the facility ID 251 is deleted from the display exclusion facility table 250. By deleting the facility from the display exclusion facility table 250, the use efficiency of the display exclusion facility table 250 can be improved and the processing load of the search exclusion processing can be reduced.

  Such maintenance processing is desirably performed periodically as described above. However, the present invention is not limited to this. For example, it may be performed in the startup process of the navigation device 100, or may be performed when the processing load of the navigation device 100 is below a certain level. Alternatively, the maintenance process may be performed as the last process of the exclusion cancellation process.

  The present invention is not limited to the above embodiment. The above embodiment can be variously modified within the scope of the technical idea of the present invention. For example, in step S002 of the search exclusion process of the above embodiment, the facility to be excluded is excluded from the display, but the present invention is not limited to this. That is, the search result output unit 107 may display so that the facility to be excluded cannot be selected in step S002. Alternatively, the facility to be excluded may be highlighted (for example, displayed with a check mark or the like). In this way, the user can grasp that the facility is set as a facility to be excluded, so it can be released in a timely manner when the exclusion of the facility to be excluded should be released. It becomes.

  Further, in the arrival exclusion process, the facility designated as the set destination is set as an exclusion target, but is not limited thereto. That is, the exclusion processing unit 108 may set not only the facility designated by the set destination but also any facility designated by the user as an exclusion target. In this way, the user can arbitrarily set the facility to be excluded. The above is an example of modification.

  In the above embodiment, an example in which the present invention is applied to an in-vehicle navigation device has been described. However, the present invention is not limited to an in-vehicle navigation device and can be applied to all navigation devices.
