Description

  The present invention relates to a navigation device that can output route guidance information to a destination set by a user and can also output information related to a destination or a facility around the route to the destination.

  Conventionally, it has already been proposed to output advertisement information in a car navigation device or a portable navigation device (hereinafter simply referred to as a navigation device) (see, for example, Patent Document 1 below).

  In the case of the technique described in Patent Document 1 below, when charging an electric vehicle, the advertisement information is displayed on the display screen of the navigation device, and in exchange for the display of such advertisement information. Part of the charge is charged to the advertisement provider, and the charge for the electric vehicle user is discounted.

  Further, in Patent Document 1 below, a store that is expected to be used from a geographical point of view such as a travel route or a destination of an electric vehicle, or a preference predicted from the gender or age group of the owner / user, It has been proposed to select and output advertisement information related to a service (see, for example, paragraph [0065] of Patent Document 1).

JP 2009-141991

  By the way, the advertisement information as described above can be output at a timing other than during charging of the electric vehicle. In particular, when it is assumed that a passenger other than the driver views the advertisement information, the vehicle is running. You may output advertisement information.

  However, the original role of the navigation device is to output the route guidance information to the destination, so when the vehicle is traveling, the route guidance information is output due to the fact that the advertisement information was output. If it is delayed, problems will arise.

  Therefore, if the vehicle is running, even if it is in the middle of outputting the advertisement information, when it reaches a point where the output of the road guidance information is necessary, the output of the advertisement information is interrupted and the road guidance is issued. I have to output information.

  However, if the output of advertising information is interrupted for such reasons, the content of the advertising information cannot be transmitted to the user if the output is interrupted. Invite.

  In addition, although the output of advertisement information can be resumed from the continuation of the interrupted location after the output of the route guidance information, if the interrupt time is long, the user may not remember the content of the advertisement information before the interrupt . For this reason, even if the output of the advertisement information is resumed, the advertisement effect may be deteriorated, for example, it becomes difficult to understand the contents of the advertisement information.

  In addition, it is possible to restart the output of the interrupted advertisement information from the beginning after the output of the route guidance information, but in the situation where the output is interrupted several times before the output is completed, the same advertisement information Only the beginning will be output many times. Therefore, there is a possibility that the advertisement may be annoying for the user, and this may also be a factor that reduces the advertising effect.

  In other words, if the output of the advertisement information is interrupted as it reaches the point where the output of the route guidance information is required, the output is continued from the beginning even if the output is interrupted and the output is subsequently resumed. Even if it was redone, there was a risk that the advertising effect would decrease as such.

  Furthermore, the output interruption of the advertisement information as described above can occur even when it is not necessary to output the route guidance information. For example, when a stop point is set in the middle of the route, if the user arrives at the stop point during the output of the advertisement information, the user leaves the vehicle at the stop point without watching the advertisement information to the end. May end up. In this case, output of advertisement information is interrupted. The same output interruption also occurs when the destination arrives during the output of the advertisement information. In these cases, since the advertisement information is not viewed until the end, it becomes a factor of reducing the advertisement effect.

  In the above explanation, the output of advertisement information was taken as an example, and the problem of the output being interrupted was pointed out. It can happen even if it is information. For example, even if it is a type of information that is not necessarily an advertisement, such as the congestion status of facilities that are set as destinations and business hours guidance, it is caused by the output of road guidance information or arrival at destinations or destinations. If the output of information is interrupted, it may be inconvenient for the user.

  The present invention has been made in order to solve the above-described problems, and the purpose of the present invention is to be able to output information on a destination or a facility around a route while the vehicle is running, and such information. It is an object of the present invention to provide a navigation device that can suppress interruption of output.

Hereinafter, the configuration employed in the present invention will be described.
In the navigation device of the present invention, the route setting means sets a route from the departure place to the destination based on the map data. The estimated required time calculating means calculates an estimated required time that is estimated to be necessary when moving in the target section, using a part or all of the route set by the route setting means as the target section.

  The information selecting means selects facility information that can be output within the estimated required time calculated by the estimated required time calculating means from the plurality of facility information. This facility information is information related to the facility selected in association with the destination or the route. For example, for example, advertisement information about the facility, various guidance information such as congestion status and business hours, etc. Corresponds to the facility information here.

  In addition, each facility information is information that can be output by at least one of video and audio, and when the information output means reaches the target section when moving along the route set by the route setting means, At least one of the video and audio starts outputting the facility information selected by the information selection means.

  Since the facility information output here is selected so that the output can be completed within the above estimated required time, the output is normally completed while moving the target section. Therefore, select a section other than the section you want to avoid the output of facility information (for example, a section where you need to output route guidance information, a section near a stop point or a destination near the destination, etc.) By doing so, it is possible to complete the output of the facility information during the travel period of a section other than the section where it is desired to avoid the output of the facility information. Therefore, it is not necessary to interrupt the output of facility information as it reaches the section where you want to avoid the output of facility information, and it is possible to suppress the decline in advertising effectiveness and missed useful information can do.

  By the way, the navigation device of the present invention stores, for each of a plurality of facility information, whether the information has already been output by the information output means or the unoutput information that has not yet been output by the information output means. Output status storage means may be provided.

  In this case, the estimated required time calculation means, when the information output means completes the output of the facility information, moves the target section using a part or all of the route scheduled to move after the completion as a new target section. Recalculating the estimated required time estimated to be necessary when the information is selected, and the information selecting means is recalculated by the estimated required time calculating means from the unoutput information based on the information stored in the output status storage means. When the information output means reaches a new target section when moving along the route set by the route setting means, the information selection means re-selects the facility information that can be output within the estimated required time. It is preferable to start outputting the re-selected facility information.

  If the non-output information is sequentially output in this way, each time the non-output information is output, the facility is dynamically calculated from the non-output information based on the latest estimated required time while recalculating the estimated required time. Information can be reselected. Therefore, even if the estimated required time changes dynamically according to the congestion condition of the road, the optimum facility information can be selected accordingly.

  Further, in the navigation device of the present invention, the estimated required time calculating means applies the section other than the road guidance information output section in which information related to road guidance is output when moving along the route set by the route setting means. It is preferable to calculate the estimated required time as a section.

  If configured in this way, since the section other than the road guidance information output section in which information about road guidance (road guidance information) is output is the target section, during the period when the road guidance information is not output, The output of facility information can be completed. Therefore, it is not necessary to interrupt the output of the facility information as it reaches the point where the output of the route guidance information is necessary, and the advertising effect is reduced or the useful information is missed. Can be suppressed.

  In the present invention, the above-described target section is not limited to a section other than the road guidance information output section, and the target section can be selected from another viewpoint. For example, if there is no particular problem with the suspension of facility information output associated with the output of route guidance information, and if the facility information output is suspended upon arrival at the destination, You may select as an object section. In other words, the present invention is a technique for completing the output of facility information while traveling in a certain target section, and what section is to be the target section may be arbitrarily changed.

  In the navigation device of the present invention, priorities may be set in advance for a plurality of facility information. In this case, the information selection means includes a plurality of facility information that can be output within the estimated required time. In some cases, it is preferable to select facility information having a higher priority.

  With such a navigation device, the facility information is output according to the priority, so that the facility information with a high priority cannot be output due to the output of the facility information with a low priority. can do.

  Further, in the navigation device of the present invention, at least one facility information among the plurality of facility information has a different time required for output, and either one of them is alternatively output as the facility information for a long time version. In this case, the information selection means may select a plurality of facilities before arrival at the destination when selecting the facility information having the long-time version facility information and the short-time version facility information. If the time T1 that is estimated to be usable for outputting information exceeds the time T2 that is estimated to be necessary when the long-term facility information is selected and a plurality of facility information is output, the long-term facility information On the other hand, when the time T1 is equal to or less than the time T2, it is preferable to select the short-time version facility information.

  With such a navigation device, long-term version facility information is output if there is sufficient time until arrival at the destination, so more detailed information can be provided to the user regarding each facility information. On the other hand, if there is not enough time before arrival at the destination, the short-time version of facility information is output, so that the number of facility information that can be provided to the user can be suppressed from decreasing.

Next, embodiments of the present invention will be described with some specific examples.
[1] First embodiment [Configuration of entire network system including navigation device]
In the network system illustrated below, as shown in FIG. 1, the navigation device 10 mounted on the vehicle 1, the mobile phone 20 connected to the navigation device 10, and the mobile phone 20 can be connected via a base station 30. A management server 50 on a wide WAN 40 (Wide Area Network; for example, the Internet). Among these, the navigation apparatus 10 includes a navigation control unit 11, a storage unit 12, a position detection unit 13, a communication unit 14, a display unit 15, a voice output unit 16, and the like.

  The navigation control unit 11 is configured around a known microcomputer including a CPU, a ROM, a RAM, and the like, and executes various processes based on a program stored in the ROM or a program loaded on the RAM. Each unit included in the navigation device 10 is controlled by the navigation control unit 11. The storage unit 12 includes a nonvolatile memory such as a flash memory and a volatile memory such as a DRAM. The storage unit 12 is a variety of information used when the navigation control unit 11 performs processing to be described later, for example, a vehicle that is information about the vehicle. It is used to store information 12A, facility information 12B output as video and audio, and the like.

  The position detection unit 13 detects a position where the vehicle 1 exists by performing processing using radio waves transmitted from an artificial satellite, map matching, or the like. The communication unit 14 is a communication interface for connecting the navigation device 10 and the mobile phone 20. In the present embodiment, the mobile phone 20 is wired to the navigation device 10 via the communication unit 14, whereby the navigation device 10 can communicate with a device (for example, the management server 50) on the WAN 40 via the mobile phone 20. become.

  The display unit 15 is a liquid crystal display disposed in the passenger compartment of the vehicle 1. In this embodiment, the display unit 15 can be used as an operation unit of the navigation device 10 by adopting a liquid crystal display with a touch panel. Has been. The display unit 15 displays map information, facility information to be described later, and the like. The voice output unit 16 is configured by a speaker or the like, and is used when outputting voice information for route guidance or facility information described later by voice.

  In the case of the present embodiment, the mobile phone 20 is installed with application software for linking with the navigation device 10. More specifically, in the present embodiment, the mobile phone 20 searches for destinations such as sightseeing spots and various commercial facilities, and relates to map information from the departure point to the destination, and facilities around the destination or the destination. Software that displays information is installed. By using this software, the user can search for a destination with the mobile phone 20 and obtain various information. Further, when the destination that the user wants to use is determined using this software, the destination information can be further transferred from the mobile phone 20 to the navigation device 10. On the side of the navigation device 10 that has received such destination information, the destination is determined based on the information transferred from the mobile phone 20 side even if an operation for setting the destination is not performed on the navigation device 10 side. Can be set.

  In the case of this embodiment, the management server 50 is a device that issues and manages coupon information in cooperation with the navigation device 10 and the mobile phone 20. More specifically, in the present embodiment, when destination information is transferred to the navigation device 10 side using software included in the mobile phone 20, when the setting on the navigation device 10 side is completed, the information is stored in the navigation device 10. The data is transmitted from the 10 side to the management server 50 via the mobile phone 20. In addition, when the output of the facility information is completed in the navigation device 10 or when the vehicle 1 reaches the destination, such information is stored in the management server via the mobile phone 20 from the navigation device 10 side. 50.

  The management server 50 that has received these pieces of information finally transmits the coupon information to the mobile phone 20 if predetermined coupon issue conditions are satisfied. The coupon information is a discount ticket or a gift exchange ticket that can be used at a facility set as a destination (or a facility around the destination), and the user presents the coupon information received by the mobile phone 20. You can receive services such as discounts and gift exchanges.

[Processing executed by navigation device, mobile phone, and management server]
Next, processing executed by the navigation device 10, the mobile phone 20, and the management server 50 in order to realize the various functions as described above will be described with reference to the flowcharts of FIGS.

  Among the processes described below, the process executed by the mobile phone 20 is that the user operates the mobile phone 20 to search for a destination and the like. This process is started when the desired destination is determined. Further, the processes executed by the navigation device 10 and the management server 50 are processes executed in conjunction with the processes in the mobile phone 20.

  Although a specific method for linking the navigation device 10 and the management server 50 with the mobile phone 20 is arbitrary, for example, the mobile phone 20 is used as a client, and the navigation device 10 and the management server 50 are used as servers. If a known client-server system is configured, processing linked to the request can be executed on the server side in response to a request from the client. Alternatively, the communication between the navigation device 10 and the mobile phone 20 are both devices owned by the user, and these devices do not need to communicate via the WAN 40, so the navigation device 10 functions as a client. Alternatively, they may be configured to cooperate with each other by other communication methods.

  When the destination desired by the user is determined by the operation on the mobile phone 20, the mobile phone 20 reads the destination information / facility information corresponding to the destination (S105), and uses the information as the navigation device 10. (S110).

  The destination information here is geographical information such as the latitude and longitude of the destination. The facility information is information regarding a facility selected in association with the destination or route (for example, a facility at the destination or a facility in the middle of the route). More specifically, it is advertisement information about the facility at the destination, various kinds of guidance information such as facility opening hours and parking lot congestion, video information displayed on the display unit 15 of the navigation device 10, and audio output And voice information output from the unit 16.

  The destination information / facility information may be read by the mobile phone 20 from the destination information / facility information providing server via the WAN 40. Alternatively, if there is no problem even if the latest information is not obtained in real time, for example, each information is obtained in advance using a device (for example, a personal computer) other than the mobile phone 20, and a memory card or the like is obtained. By storing each information in the medium, the medium may be set in the mobile phone 20 and the destination information / facility information may be read from the medium. Further, the map data and the facility information may be associated in advance and stored in a medium for the navigation device 10 to refer to the map data.

  When such destination information / facility information is transmitted from the mobile phone 20, the navigation device 10 receives the destination information / facility information from the mobile phone 20 (S205). Is used to acquire position information of the current location of the vehicle 1 (S210), and the position information and destination information / facility information are combined and transmitted to the cellular phone 20 as identification information (S220).

  The cellular phone 20 receives the identification information transmitted from the navigation device 10 (S115), and transmits the identification information to the management server 50 (S120). The management server 50 receives the identification information, recognizes the current position of the vehicle (S305), and determines whether the identification information is correct information (S310).

  As a result of the determination in S310, when it is determined that the identification information is not correct information (S310: NO), the management server 50 ends the process. At this time, since the mobile phone 20 and the navigation device 10 cannot receive the authentication information even after a predetermined time has elapsed, a time-out error occurs and the processing ends.

  On the other hand, as a result of the determination in S310, when it is determined that the identification information is correct information (S310: YES), the management server 50 transmits the authentication information (S315). The mobile phone 20 receives the authentication information (S125), and transmits the authentication information to the navigation device 10 (S130).

  The navigation device 10 determines whether or not the authentication information has been received (S225). If the authentication information cannot be received (S225: NO), the process ends. Note that when the process ends in this way, the process ends without an appropriate destination setting being performed, but this is only an error as a result of executing the destination setting using the mobile phone 20 once. Absent. Therefore, after this, for example, it is possible to directly operate the navigation device 10 to perform destination setting, or to retry destination setting using the mobile phone 20.

  On the other hand, if the authentication information can be received in S225 (S225: YES), the destination setting is performed based on the destination information received in S205 and the vehicle position information acquired in S210 (S230). Thereby, in the navigation apparatus 10, the route to the destination is set based on the map data, and thereafter, the route guidance information can be output. The navigation control unit 11 that executes S230 corresponds to the route setting means in the present invention.

  Then, when the vehicle 1 starts moving toward the destination, the navigation device 10 starts outputting the route guidance and facility information (S235). This S235 is a process as shown in detail in FIG.

  That is, when the process shown in FIG. 3 is started, the navigation apparatus 10 acquires the latest vehicle position information (S405), and determines whether or not the route guidance information output section has been reached (S410). Here, for example, as shown in FIG. 4A, the road guidance information output section is necessary for road guidance from a reference point with respect to a point where road guidance such as a left turn or a right turn is necessary. This is a section (the section information output time illustrated in FIG. 4: a section of 20 seconds) that is set with a point just before the time as a start point.

  If the road guidance information output section has been reached (S410: YES), the navigation device 10 outputs the road guidance information (S415). When the output of the route guidance information is completed, the process returns to S405. On the other hand, if it is determined in S410 that the road guidance information output section has not been reached (S410: NO), the navigation device 10 determines whether or not the vehicle 1 has arrived at the destination (S420).

  If it is determined in S420 that the vehicle has not arrived at the destination (S420: NO), the navigation device 10 determines whether all facility information has been output (S425). In the present embodiment, a plurality of facility information is prepared, and the facility information is sequentially selected and output from the plurality of facility information in the processing described later. Then, whether or not each of the plurality of facility information is output is stored by the output completion flag in the management storage area as illustrated in FIG.

  In S425, the output completion flag stored in the management storage area is checked, and the output completion flag corresponding to each of a plurality of facility information (six facility information D1 to D6 are illustrated in FIG. 4B). If everything is ON, it is determined that all facility information has been output, while if any one of the output flags is OFF, all facility information has been output. Judge that there is no.

  Here, the description is continued assuming that there is facility information that has not been output. If there is facility information that has not been output, a negative determination is made in S425 (S425: NO), and in this case, the navigation device 10 calculates the free time until the next route guidance information is output (S430). In S430, based on the current position acquired in S405, the distance to the next road guidance information output point acquired from the map data is obtained, and the time required to move the distance is calculated based on the current vehicle speed. To estimate. In addition, the navigation control part 11 which performs this S430 is equivalent to the estimated required time calculation means referred to in the present invention.

  After obtaining the estimated required time in S430, the navigation apparatus 10 determines whether there is unoutput facility information that satisfies the vacant time until the next road guidance information output> output time (S435). Since the output time of each facility information is stored in the management storage area previously illustrated in FIG. 4B, in S435, the corresponding storage information is output with reference to the management storage area. To determine whether one or more pieces of facility information have been selected.

  In S435, if it is determined that there is facility information that has not been output (S435: YES), the navigation apparatus 10 outputs the facility information that has not been output that satisfies the idle time> output time until the next route guidance information is output. Facility information with the maximum time × priority coefficient is selected and output (S440). The navigation control unit 11 that executes S440 corresponds to the information selection unit and the information output unit in the present invention.

  In S440, the facility information is output as video and audio, and as shown in FIG. 4C, the route guidance screen is displayed on the left half of the screen on the display unit 15 of the navigation device 10, and the right half of the screen. The facility information is displayed. In this way, if the facility information screen is displayed next to the route guidance screen and an advertisement is displayed in the facility information screen, the advertisement can be reproduced without obstructing the route guidance by the navigation device 10. it can. In addition, which range is used for the display of facility information is arbitrary. For example, the left and right may be opposite to those illustrated in FIG. 1/3 or 1/4 of the screen may be used for facility information display. Alternatively, the user may arbitrarily set them.

  In S440, facility information with a longer output time is preferentially output if the priority coefficient is approximately the same, and facility information having a higher priority coefficient is preferentially output if the output time is approximately the same. Will be. In addition, the priority coefficient of each facility information is stored in the management storage area illustrated in FIG.

  After finishing S440, the navigation apparatus 10 memorize | stores the output facility information as having been output (S445). In S445, the output completion flag (see FIG. 4B) corresponding to the output facility information is changed to ON. In S445, the storage area for storing the output completion flag corresponds to the output status storage means in the present invention.

  Then, the management server 50 is notified of information relating to the facility information that has been output (S450). In S450, the navigation device 10 communicates with the management server 50 via the mobile phone 20. However, since the technology itself for connecting to the WAN 40 using the mobile phone 20 is well known, further explanation is omitted.

  When S450 is completed in this manner, the process returns to S405, and thereafter, unless affirmative determination is made in S420, some of the above-described steps S405 to S450 are repeatedly executed in sequence. In the meantime, when the route guidance information is not output (410: NO), the available time until the next route guidance information is output is always calculated (S430), and if there is facility information whose output is completed within the available time (S435). : YES), while the facility information is output (S440), if there is no facility information to be output within the free time (S435: NO), the process returns to S405 to postpone the output of the facility information.

  If such a process is performed, for example, when the route as shown in FIG. 4A is set, the navigation device 10 may select the intersection C1 to be guided next and the starting point that is the current location. A free time 18 [seconds] from the distance between the vehicle and the estimated traveling speed to the road guidance is calculated. The facility information expected to be output within this time is all the facility information D1 to D6 shown in FIG. 4B, and among these, the facility information D1 having the highest “output time × priority coefficient” Select to start output. The facility information D1 that has been output before the guidance for the intersection C1 has its output flag turned ON after the output, and the output completion information is transmitted to the management server 50 via the mobile phone 20.

  After the output of the facility information D1 is completed, there is only the remaining 3 seconds until the guidance of the intersection C1, and referring to the information shown in FIG. 10 outputs nothing until the guidance of the intersection C1. Since the time required for the intersection C2 after the end of the route guidance for the intersection C1 is 14 [seconds], in this case, facility information other than the facility information D2 is output. At this time, when “output time × priority coefficient” is calculated, the facility information D3 is selected and output as the next output target from the calculation result, and the output completion flag processing and management are performed in the same manner as the previous processing after output. Notification to the server 50 is performed. Further, if it is determined that it takes 24 [seconds] from the intersection C2 to the next guidance point, the navigation device 10 outputs the facility information D2, and then outputs the facility information D6.

  Therefore, in the case of the navigation device 10 that performs the processing as described above, normally, while traveling in a section other than the road guidance information output section, the facility information is output within the estimated required time required for traveling in that section. Can be completed, and route guidance information can be output after the completion. In other words, the possibility of reaching the route guidance information output section while outputting facility information is extremely low, and the output of route guidance information is not delayed due to the output of facility information. Moreover, the output of the facility information is not interrupted because the route guidance information is output without delay. Therefore, when advertising information is output as facility information, the advertising effect can be enhanced. Moreover, even when a parking lot congestion situation or other useful information is output as facility information, it is possible to prevent the output of such information from being interrupted.

  In addition, when all the facility information has been output by the above processing (S425: YES), the process returns to S405, and thereafter, until arrival at the destination (S420: NO), S405 The process is repeated in S425. When the vehicle arrives at the destination (S420: YES), the processing shown in FIG. 3 is terminated, and S235 shown in FIG. 2 is finished.

  After finishing S235, the navigation apparatus 10 will transmit arrival information to the mobile telephone 20, and the process in the navigation apparatus 10 will be completed. On the other hand, the cellular phone 20 receives the arrival information sent from the navigation device 10 (S135), and transmits the arrival information to the management server 50 (S140). The management server 50 receives the arrival information sent from the mobile phone 20 (S320), and determines whether the arrival information is correct (S325). In S325, it is determined whether the destination information set in advance and the arrival information correspond correctly, whether the facility information is output properly, and the like.

  As a result of the determination in S325, when it is determined that the arrival information is correct (S325: YES), the management server 50 transmits coupon information to the mobile phone 20, and ends the processing in the management server 50. If it is determined that the arrival information is not correct (S325: NO), the management server 50 ends the processing in the management server 50 without transmitting coupon information to the mobile phone 20. When coupon information is transmitted from the management server 50 to the mobile phone 20, the mobile phone 20 receives the coupon information, and the processing in the mobile phone 20 is completed.

  Note that the coupon information issued here may be issued uniformly to any user, but considering cooperation with the navigation device 10, for example, the longer the travel distance, the lower the discount. You may employ | adopt the mechanism by which coupon information with a high amount and a discount rate is issued.

  In addition, the travel distance is not just linked to the discount rate, but if the travel distance is long, the time that the facility information can be provided also increases, so the amount of facility information provided is increased accordingly, and many facilities are provided. The system may be such that coupon information with a higher discount amount or discount rate is issued to the user who has viewed the information. In that case, as a method of increasing the provision amount of facility information, the number of facility information may be increased, or one facility information may be output for a longer time. Further, such coupon information is not limited to information that can be used at the destination, but can be used in the middle of the route to the destination (for example, a parking lot on the route or a parking lot near the destination) Can be used).

[effect]
According to the navigation apparatus 10 as described above, a section other than a section in which facility information is not desired to be output (in the above embodiment, a section that requires output of road guidance information) is set as a target section, and the target section travels. The facility information output can be completed during the period. Therefore, it is not necessary to interrupt the output of the facility information as it reaches the section where you want to avoid the output of the facility information. can do.

  Also, the facility information output timing is such that when the vehicle 1 only needs to travel along the road, there is no significant impact on the maintenance of the travel route without detailed guidance using a map or voice. Since it is performed, the original function of the navigation device 10 is not impaired.

  In addition, when the output of one piece of unoutput information is completed, the navigation device 10 outputs the next piece of non-output information with a part or all of the route scheduled to move after the completion as a new target section. Before, since the estimated required time is recalculated by executing S430 again, the facility information can be dynamically selected from the unoutput information based on the latest estimated required time. Therefore, even when the estimated required time changes dynamically according to the congestion situation of the road, the optimum facility information can be selected and output accordingly.

  Furthermore, according to the navigation device 10, facility information with a long output time is output relatively preferentially if there is a free time, but the facility information is output according to an arbitrarily set priority. . Therefore, for example, even if the facility information has a short output time, if the priority is set high, priority output is possible. Therefore, if the priority is adjusted, the facility information with low priority is displayed. It can be avoided that facility information having a high priority cannot be output due to the output.

  Such a priority can be arbitrarily set by the provider of the facility information, but the user of the vehicle 1 further registers his / her hobbies and interests, and the user's preferences, etc. In addition, each facility information may be prioritized in advance. In this way, high-priority advertising information that is of interest to the user can be output as soon as possible, and the advertising effect on the user can be enhanced.

  In addition, when the priority is set by reflecting such user's preference etc., the coupon information reflecting the user's preference etc. is also issued for the coupon information finally issued, Even more preferred. Or, if you adopt a mechanism that allows you to apply in advance for coupon information that the user wants to issue, you can easily issue coupon information as desired by the user without guessing the user's preference Is possible. In addition, if advertisement information is displayed as facility information, coupon information corresponding to the advertisement information may be used.

[2] Second Embodiment Next, a second embodiment will be described. However, the second embodiment differs from the first embodiment in that some of the processes executed by the navigation device 10 are the same as the first embodiment, but are different in the following description. It will be described in detail with a focus on the points, and for parts equivalent to the first embodiment, the same reference numerals as those in the first embodiment are used if necessary, and the description overlapping with the first embodiment will be omitted.

  The second embodiment is different from the first embodiment in the subsequent process after the negative determination is made in S425 shown in the first embodiment. That is, in S425, when there is facility information that has not been output (S425: NO), the navigation apparatus 10 calculates the time (A) required for arrival at the destination (S505). In S505, based on the current position acquired in S405 (see FIG. 3), the distance to the acquired destination is obtained from the map data, and the time required for moving the distance is set to the current vehicle speed. Estimate based on.

  In addition, the navigation device 10 calculates a total value (B) of time required for outputting the route guidance information before arrival at the destination (S510). In S510, the time required for information output at each point where road guidance is scheduled is integrated for the entire route.

  Furthermore, the navigation apparatus 10 calculates the total time (C) required for outputting a non-output advertisement (a long-time version and a long-time version if there is a short-time version) with a priority coefficient greater than 1 (S515). ). Here, in the case of the second embodiment, as illustrated in FIG. 6, some facility information includes long-time version facility information and short-time version facility information, which can be selectively selected and output. It is said that.

  These long-time version facility information and short-time version facility information have different output times, and in the process described later, if there is room for free time, long-time version facility information is selected and output, and there is room for free time. If there is no short-term facility information is selected and output. In S515, based on the output time of the long-time version facility information, the total value (C) of the time required to output the non-output advertisement with the priority coefficient greater than 1 is calculated.

  Subsequently, the navigation device 10 calculates a free time until the next road guidance information is output (S520). In this S520, based on the current position acquired in S405 (see FIG. 3), the distance to the next route guidance information output point acquired from the map data is obtained, and the time required to move the distance is calculated. Estimate based on current vehicle speed. In addition, the navigation control part 11 which performs this S520 corresponds to the estimated required time calculation means in the present invention.

  Then, after obtaining the estimated required time in S520, the navigation apparatus 10 determines whether or not the magnitude relationship thereof is (A−B)> C based on the times A, B, and C obtained in S505 to S515. Determination is made (S525). Here, (A-B) corresponds to the accumulated value of free time during which no road guidance information is output. If (A-B)> C (S525: YES), long-term facility information is displayed. Even if it is output, it can be estimated that there is room in free time. On the other hand, if (A−B)> C is not satisfied (S525: NO), there is a possibility that not all facility information can be output during the free time when the long-term facility information is output.

  Therefore, if (A−B)> C in S525 (S525: YES), the navigation device 10 determines that there is no output facility information (long-duration version and long time until the next route guidance information output> output time> It is determined whether there is a long time version if there is a short time version (S530). Since the output time of each facility information is stored in the management storage area illustrated in FIG. 6, in S530, the corresponding storage information is selected by referring to the management storage area. It is determined whether the above facility information has been selected.

  If it is determined in S530 that there is facility information that has not been output (S530: YES), the navigation device 10 determines that the facility information that has not been output (free time until the next route guidance information output> output time (long-term version). If there is a short version, the facility information having the maximum output time × priority coefficient is selected and output (S535). The navigation control unit 11 that executes S535 corresponds to an information selection unit and an information output unit in the present invention. Note that the facility information is output to the display unit 15 of the navigation device 10 in the form illustrated in FIG. 4C by this S535, but this display form can be changed variously. It is the same as that of one embodiment. The priority coefficient of each facility information is stored in the management storage area illustrated in FIG.

  After finishing S535, the navigation apparatus 10 stores both the long-time version and the short-time version of the facility information that has been output as being output (S540). In S540, the output completion flag (see FIG. 6) corresponding to the output facility information is changed to ON. In S540, the storage area for storing the output completion flag corresponds to the output status storage means in the present invention. As illustrated in FIG. 6, the output flag storage area is a single storage area associated with both the long-time version and the short-time version of the facility information. If the output completion flag ON is stored, both the long-time version and the short-time version are stored as being output.

  On the other hand, if (A−B)> C is not satisfied in S525 (S525: YES), the navigation device 10 determines that there is no output facility information (long-duration version and long time until the next road guide information output> empty time> output time. It is determined whether or not there is a short time version (S545). In S545 as well, as in S530, it is determined whether or not one or more pieces of facility information have been selected by referring to the management storage area (see FIG. 6).

  If it is determined in S545 that there is facility information that has not been output (S545: YES), the navigation apparatus 10 determines that there is facility information that has not been output (free time until the next route guidance information output> output time (long-term version). If there is a short time version, the facility information with the maximum output time × priority coefficient is selected and output (S550). The navigation control unit 11 that executes S550 corresponds to an information selection unit and an information output unit in the present invention. Note that the facility information is output to the display unit 15 of the navigation device 10 in the form illustrated in FIG. 4C by S550, as in S535.

When S550 ends, the process proceeds to S540 described above, and the navigation apparatus 10 stores both the long-time version and the short-time version of the output facility information as output (S540).
When S540 is completed, the process returns to S450 shown in FIG. If it is determined that there is no facility information that has not been output in S530 or S545 shown in FIG. 5 (S530: NO or S545: NO), the process returns to S405 shown in FIG. If the process returns to S405 or S450 shown in FIG. 3 in this way, thereafter, if a negative determination is made in S425, the process goes again to S505 shown in FIG.

[effect]
The navigation device 10 of the second embodiment as described above also has the same operations and effects as the navigation device 10 of the first embodiment.

  Moreover, in the case of the navigation device 10 of the second embodiment, the time (AB) estimated to be usable for outputting facility information before arrival at the destination (corresponding to the time T1 in the present invention) is long. If it is longer than the time C (equivalent to the time T2 in the present invention) estimated to be necessary when the version facility information is selected and the facility information is output, the long-term version facility information is selected. When the time T1 is equal to or shorter than the time T2, the facility information of the shortened version is selected and output.

  Therefore, unlike the case of outputting only facility information corresponding to the long-time version, it is possible to suppress the problem that there is not enough free time and the number of facility information that can be output is reduced, and the priority is high. More facility information can be provided in order from the facility information. Also, unlike the case of outputting only the facility information corresponding to the short-time version, it is possible to suppress the problem that the amount of information of each facility information is reduced even though there is a spare time.

[3] Other Embodiments Although the embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment described above, and can be implemented in various other forms.

  In the above embodiment, an example is shown in which the overlap between the output period of the route guidance information and the output period of the facility information is shown. However, there are other periods in which the overlap with the output period of the facility information is to be avoided. It is possible to assume any period, and what kind of period is to be avoided may be arbitrarily determined according to the purpose and the design concept of the apparatus.

  For example, the section near the stop point set in the middle of the route may be a section where the facility information is not output except in the period for outputting the route guidance information. In this case, the facility information is output near the stop point. Is completed, so it is possible to reach the stop point without interrupting the output of the facility information. Further, the output of facility information may be completed in the vicinity of the destination, whereby the destination can be reached without interrupting the output of facility information.

  These route guidance information output periods, stop points, and destinations may be all sections that do not output facility information, but only one of them may be adopted, and It may be possible for the user to arbitrarily select and set whether to adopt.

  Moreover, although the navigation apparatus 10 and the mobile telephone 20 were connected and the example which performs reception of coupon information was shown in the said embodiment, if the communication function is integrated in the navigation apparatus 10, the mobile telephone 20 and Whether or not to perform the connection is arbitrary. In this case, since the navigation device 10 receives the coupon information, if the coupon information is finally transferred to the mobile phone 20 and brought into the facility, the coupon information is transferred from the navigation device 10 to the mobile phone 20, Coupon information may be stored in a medium set in the navigation device 10 and the medium may be set in the mobile phone 20.

  Further, in the above embodiment, when the destination is set, the facility information is output while moving to the destination. However, when the return route from the destination is further selected, the facility information is also displayed at that time. May be output. In this case, for example, if the destination is a commercial facility, it is effective to output advertisement information etc. for encouraging the next visit. In that case, coupon information that can be used at the next visit may be issued. Is possible.
