Description

  The present invention relates to an in-vehicle wireless communication system, an in-vehicle wireless communication apparatus, and a mobile terminal, and is particularly suitable for use in an in-vehicle wireless communication system configured to be able to perform wireless communication by connecting to an external access point from within the vehicle. Is something.

  In recent years, in-vehicle wireless communication systems using wireless communication such as Wi-Fi have become widespread in vehicles such as automobiles. In the in-vehicle wireless communication system, for example, a plurality of wireless communication devices can be linked by wirelessly connecting a plurality of wireless communication devices in the vehicle (for example, between the in-vehicle device and the portable terminal) to each other. In addition, in an in-vehicle wireless communication system, a wireless communication device (for example, an in-vehicle device or a portable terminal) in a vehicle connects to an access point (wireless antenna device) installed outside the vehicle via the access point. Internet access.

  As described above, when connecting from an in-vehicle wireless communication device to an access point installed outside the vehicle, the wireless communication range of each access point is limited (for example, 400 to 1000 m). In order to prevent communication from being interrupted, a method of sequentially switching connection destination access points is used. Accordingly, in recent years, access points have been installed in more facilities along the road so as not to cause an area outside the communication range of the access points.

  For facilities where access points are installed, providing distribution information related to the facilities to wireless communication devices used in a vehicle traveling in the vicinity of the facility as a price for providing access point functions free of charge Thus, it becomes possible to advertise the facility and advertise products and services handled by the facility. At this time, the distribution information related to the user's preference is displayed on the wireless communication device in the vehicle, so that the advertising effect by the distribution information can be further enhanced. Therefore, conventionally, a technique has been devised in which distribution information related to user preferences is provided to a user from a wireless communication device.

  For example, in the following Patent Document 1, the type of information required by a user (for example, a product of interest, a disembarking station, etc.) is set in advance in a mobile terminal owned by the user, and within a limited area ( For example, a technology is disclosed in which a mobile terminal that has received information transmitted in a train, a store, etc. outputs only the information that the user needs among the received information and provides it to the user.

  In Patent Document 2 below, user preference information is transmitted from the in-vehicle device to the roadside device by DSRC (Dedicated Short Range Communication) (registered trademark), and the user is interested in the roadside device based on the preference information. A technique for selecting advertisement information that is considered to be high and distributing the advertisement information to an in-vehicle device is disclosed.

  Patent Document 3 below discloses a technology in which an in-vehicle device mounted on a vehicle acquires advertisement information by DSRC from a roadside wireless device installed outside the vehicle, and displays the advertisement information on a display unit. ing. In particular, Patent Document 3 below describes that in-vehicle equipment is controlled so as not to permit reception of advertisement information other than the preference genre input by the user.

JP 2003-264517 A JP 2005-134707 A JP 2013-47976 A

  In the future, it is expected that a facility where a wireless communication access point is installed will provide distribution information related to the facility to a wireless communication device connected to the access point. As described above, as a price for providing the access point functions free of charge, the facility is advertised to users who use the access point, and the products and services handled by the facility are advertised. .

  However, when a conventional on-vehicle wireless communication device switches an access point while the vehicle is running, the access point switching destination is selected based on the received radio wave intensity or the like as a selection criterion. That is, the access point with the strongest received radio wave intensity is selected and connected at the switching timing. In this case, the distribution information provided through the selected access point is not necessarily related to the user's preference, and if it is viewed from the facility where the access point is installed, the advertising effect by the distribution information cannot be improved. There was a problem.

  In addition, in the above Patent Documents 1 to 3, a mechanism for selecting and providing information related to the user's preference is disclosed, but in a case where only information related to the facility is distributed from the access point of the facility. It cannot be applied. In other words, the techniques described in Patent Documents 1 and 3 have a mechanism in which the in-vehicle device receives various types of information and selects only the information that suits the user's preference from the information. However, in the case where only information related to a specific facility is distributed through the selected access point, there is no room for selecting information on the in-vehicle device side. In addition, since the technology described in Patent Document 2 has a mechanism for selecting and distributing information suitable for the user's preference in the roadside device, the facility where the roadside access point is installed only has information related to the facility. In the first place, it cannot be applied to the case of delivering.

  The present invention has been made to solve such a problem, and enables connection to an appropriate access point so that information related to user preferences is provided to the user. With the goal.

  In order to solve the above-described problem, in the present invention, a user's preference is specified based on information that can specify the user's preference. Then, an access point installed around the vehicle is detected, and an access point installed in a facility related to the user's preference is selected preferentially from the detected plurality of access points, Make a wireless communication connection to the access point. Furthermore, the distribution information distributed from the access point connected by wireless communication is received, and the distribution information is displayed on the display.

  According to the present invention configured as described above, when the connection point of the access point is switched while the vehicle is running, the access point installed in the facility related to the user's preference is preferentially connected. Become. As described above, information related to the facility is distributed through the access point from the facility where the access point is installed. Therefore, by connecting to an access point installed in a facility related to the user's preference, information related to the user's preference is provided to the user.

  On the other hand, the smartphone 20 according to the present embodiment includes an access point detection unit 201, a first wireless communication unit 202a, a second wireless communication unit 202b, and a distribution information reception unit 203 as its functional configuration. The smartphone 20 includes an action history information storage unit 20c.

  Each of the functional blocks 100 to 110 and 201 to 203 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the functional blocks 100 to 110 and 201 to 203 is actually configured by including a CPU, RAM, ROM, and the like of a computer, and is stored in a recording medium such as a RAM, a ROM, a hard disk, or a semiconductor memory. This is realized by operating the stored program.

  The action history information storage unit 20 c stores action history information of the user of the smartphone 20. This behavior history information is used by the preference estimation unit 103 of the navigation device 10 to specify the user's preference by estimating the preference. In other words, the action history information is an example of “information that can identify user preferences” described in the claims. As action history information, the browsing history of the internet by the smart phone 20 can be used, for example. In this case, each time the user browses the Internet using the smartphone 20, the history information is recorded in the behavior history information storage unit 20c as behavior history information in the behavior history information storage unit 20c. Internet browsing history includes, for example, Internet search history, Internet shopping purchase history, advertisement information click history, and the like. In either case, information that can extract a word for estimating the user's preference is included. For example, the search history includes information such as a search keyword as information from which a word can be extracted. Further, the purchase history includes information such as product names as information from which words can be extracted. Further, the click history includes character information related to the advertisement content as information from which the word can be extracted.

  The wireless communication unit 100 controls wireless communication with the smartphone 20 by establishing a wireless communication connection with the smartphone 20 using Bluetooth.

  The information acquisition unit 102 acquires user action history information from the action history information storage unit 20 c of the smartphone 20 via wireless communication with the smartphone 20 by the wireless communication unit 100.

  The preference estimation unit 103 estimates the preference of the user of the smartphone 20 based on the action history information acquired by the information acquisition unit 102. Thereby, the preference estimation part 103 specifies the user's preference of the smart phone 20. For example, the preference estimation unit 103 selects the word registered in the word dictionary from the action history information (for example, browsing history on the Internet) based on the word dictionary in which the association between the word and the genre is registered in advance. To extract. Then, the preference estimation unit 103 estimates a genre having a higher word appearance frequency as a genre preferred by the user from a plurality of genres registered in the word dictionary.

  The preference estimation part 103 may estimate a some genre as a genre which a user likes. In this case, the preference estimation unit 103 may set a priority for each genre based on the appearance frequency of words, for example. For example, “automobile” and “gourmet” are estimated as user preferences, the priority of “automobile” is “high”, and the priority of “gourmet” is “low”.

  The access point detection unit 201 detects an access point 30 installed around the vehicle. Specifically, the access point detection unit 201 receives radio waves radiated from the access point 30 by an antenna (not shown) provided in the smartphone 20 when the vehicle enters the wireless communication area of the access point 30. Thus, the access point 30 is detected. When a vehicle enters the wireless communication area of the plurality of access points 30, the access point detection unit 201 detects the plurality of access points 30.

  Information that can identify the access point 30 is set in the radio wave distributed from the access point 30. Information that can specify the access point 30 includes, for example, identification information of the access point 30, location information of the access point 30 (for example, latitude / longitude, address, etc.), and facilities of the facility where the access point 30 is installed. Information (for example, facility name, latitude / longitude, address, telephone number, genre, etc.) is used.

  When detecting one or a plurality of access points 30, the access point detection unit 201 generates an access point list 600 (see FIG. 6) indicating access point information of the detected one or more access points 30. Then, the access point detection unit 201 transmits the access point list 600 to the navigation device 10 by wireless communication with the navigation device 10 by the second wireless communication unit 202b. In the access point list 600, access point information regarding the access point 30 is shown for each of one or more access points 30. For example, in the example illustrated in FIG. 6, the access point list 600 includes access point information 602 a to 602 d for each of the four access points 30. Each of the access point information 602a to 602d includes the name of the facility where the access point 30 is installed and the received radio wave intensity (antenna bar). Among these, the facility name of the facility where the access point 30 is installed is an example of information that can identify the access point 30 described above.

  The access point selection unit 104 is estimated by the preference estimation unit 103 from the plurality of access points 30 detected by the access point detection unit 201 (that is, the plurality of access points 30 shown in the access point list 600). The access point 30 installed in the facility related to the user's preference is preferentially selected. For example, when “automobile” is estimated as the user's preference by the preference estimation unit 103, the access point selection unit 104 is an access installed in a facility related to the vehicle (for example, a car dealership, a gas station, etc.). Point 30 is preferentially selected. When the access point selection unit 104 selects the access point 30, the selection result is transmitted to the first wireless communication unit 202a via the second wireless communication unit 202b of the smartphone 20 by wireless communication with the smartphone 20 by the wireless communication unit 100. Supplied.

  The access point 30 of the facility related to the user's preference is, for example, information (for example, the name of the facility, the location information of the facility, the access point 30) shown in the access point list 600 that can identify the access point 30. Position information, etc.). For example, when the user's preference is “automobile”, the access point selection unit 104, when the facility name shown in the access point list 600 includes a word related to the genre “automobile”, the facility name Can be identified as the access point 30 of the facility related to the user's preference.

  When the user preference is “automobile”, the access point selection unit 104 displays the location information of the facility or access point 30 shown in the access point list 600 and the map data stored in the map information storage unit 10c. The facility where the access point 30 is installed is identified. Then, in the map information storage unit 10c, when the facility data of the facility includes a word related to the car, or when the facility is classified into a genre related to the car, the access point 30 is It can be specified as the access point 30 of the facility related to the user's preference.

  When the user's preference is “automobile”, the access point selection unit 104 refers to a table in which the association between the genre and the word is registered in advance, for example, so that the word related to the genre “automobile” Can be identified.

  Note that when there are a plurality of facility access points 30 related to the user's preference in the access point list 600, the access point selection unit 104 selects one of the access points 30 based on a predetermined condition. Is selected as the access point 30 that is actually the connection destination. For example, the access point selection unit 104 may select the access point 30 having a stronger received radio wave intensity as the access point 30 that is actually the connection destination.

  In addition, in the case where a plurality of user preferences are estimated by the preference estimation unit 103 and the respective priorities of the estimated plurality of preferences are set, a plurality of estimated preferences are stored in the access point list 600. When each access point 30 exists, the access point selection unit 104 may select an access point 30 having a high priority as an access point 30 that is actually a connection destination. For example, when the preference estimation unit 103 estimates “automobile” and “gourmet” as user preferences, “high” is set for the priority of “automobile” and “low” for the priority of “gourmet” ”Is set, the access point 30 of the facility related to the automobile is preferentially selected.

  In addition, when there are a plurality of facility access points 30 related to the user's preference in the access point list 600, the access point selection unit 104 is installed in a facility with a higher degree of association with the current time. The point 30 may be selected as the access point 30 that is actually the connection destination of wireless communication. For example, when an access point 30 of a facility that is likely to be visited by a user during a specific time period (for example, evening) such as a grocery store is shown in the access point list 600, the access point selection unit 104 In that particular time zone, the access point 30 may be preferentially selected.

  Further, when there is no access point 30 of the facility related to the user's preference in the access point list 600, the access point selection unit 104 selects the access point 30 from the plurality of access points 30 shown in the access point list 600. Based on a predetermined selection condition, one of the access points 30 (for example, the access point 30 with stronger received radio wave intensity) is selected. Thereby, even when the access point 30 of the facility related to the user's preference does not exist in the access point list 600, wireless communication is prevented from being interrupted by connecting to any one of the access points 30. be able to.

  The first wireless communication unit 202 a establishes a Wi-Fi wireless communication connection with the access point 30 selected by the access point selection unit 104 and controls wireless communication with the access point 30 by Wi-Fi. The second wireless communication unit 202b establishes a wireless communication connection with the navigation device 10 based on Bluetooth, and controls wireless communication with the navigation device 10.

  The distribution information receiving unit 203 receives the distribution information distributed from the access point 30 through wireless communication with the access point 30 by the first wireless communication unit 202a. The distribution information distributed from the access point 30 includes facility information (for example, facility name, address, telephone number, etc.) regarding the facility where the access point 30 is installed, advertisement information (for example, campaign information, sale information, recommendation) Product information etc.). The distribution information receiving unit 203 supplies the distribution information received from the access point 30 to the display control unit 105 via the wireless communication unit 100 by wireless communication with the navigation device 10 by the second wireless communication unit 202b. The distribution information is displayed on the display 10 a included in the navigation device 10 under the control of the display control unit 105.

  When the display control unit 105 displays the distribution information on the display 10a, the entry permission / prohibition determination unit 106 is wirelessly connected to the current location of the vehicle by the distribution source facility (that is, the wireless communication unit 202). It is determined whether or not it is in a position where it can enter the facility where the access point 30 is installed.

  For example, the entry permission / non-permission determination unit 106 specifies the facility from which the distribution information is distributed based on the selection result of the access point 30 by the access point selection unit 104 and the map data stored in the map information storage unit 10c. . Then, the entrance determination unit 106 determines the entrance of the distribution source facility from the current position of the vehicle specified by the current position specifying unit 110 and the map data stored in the map information storage unit 10c. If it is determined that the vehicle is located ahead of the current position in the traveling direction, it is determined that “the current position of the vehicle is at a position where the vehicle can enter the facility to which the distribution information is distributed”. On the other hand, when the entrance determination unit 106 determines that the entrance of the facility from which the distribution information is distributed is located behind the current position of the vehicle in the traveling direction, “the facility where the current position of the vehicle has distributed the distribution information” It is determined that it is not in a position where it can enter.

  When the entry control unit 106 determines that “the current position of the vehicle is at a position where the vehicle can enter the facility where the distribution information is distributed”, the display control unit 105 displays the distribution information of the distribution information together with the distribution information. The guidance information to the facility is displayed on the display 10a. The guidance information to the facility is, for example, the guidance name 710a of the guidance destination facility, the distance 710b to the entrance of the guidance destination facility, and the guidance destination facility as seen from the position of the vehicle, such as guidance information 710 shown in FIG. There is a direction 710c or the like. In this case, the distance 710b and the direction 710c are determined by the approach determination unit 106 based on the current position of the vehicle specified by the current position specifying unit 110 and the map data stored in the map information storage unit 10c. Desired.

  On the other hand, when the entry control unit 106 determines that “the current position of the vehicle is not at a position where the vehicle can enter the facility where the distribution information is distributed”, the display control unit 105 distributes the distribution information together with the distribution information. Information on guidance to the related facility of the original facility is displayed on the display 10a. The guide information to the related facility is, for example, the guide name 810a of the related facility of the guide destination, the distance 810b to the entrance of the related facility of the guide destination, and the guide destination as seen from the position of the vehicle The direction of the related facility is 810c. In this case, the distance 810b to the entrance of the related facility and the direction 810c where there is the related facility of the guidance destination as seen from the own vehicle position are stored in the map information storage unit 10c and the current position of the vehicle specified by the current position specifying unit 110. Based on the stored map data, the entry permission / prohibition determination unit 106 obtains the map data.

  Further, the related facility of the distribution source distribution facility is specified by the related facility specifying unit 107. For example, the related facility specifying unit 107 specifies, as a related facility, a facility that satisfies a predetermined similarity condition with the distribution source distribution facility based on the facility data stored in the navigation device 10. A facility that satisfies a predetermined similarity condition is, for example, a facility having the same facility name, a facility belonging to the same sales line, or the like. When there are a plurality of facilities that satisfy the predetermined similarity condition, the related facility specifying unit 107 may specify a plurality of facilities as the related facilities. Alternatively, a facility that is located forward in the traveling direction of the vehicle and that is closest to the current position of the vehicle may be specified as a related facility. The related facility may be indicated in the distribution information distributed from the access point 30.

  The operation reception unit 108 receives a user operation input from the touch panel 10b. For example, as shown in FIG. 8, when guidance information 810 to a related facility is displayed on the display 10a, the operation reception unit 108 receives a predetermined operation using the touch panel 10b. When the operation receiving unit 108 receives a predetermined operation from the touch panel 10b, the route search unit 109 and the map stored in the map information storage unit 10c are identified by the current position of the vehicle specified by the current position specifying unit 110. Based on the data, a guidance route from the local position of the vehicle having the related facility as the destination is searched. The guidance route searched in this way is displayed on the display 10a under the control of the display control unit 105, and is used when performing route guidance to the related facility by the navigation function provided in the navigation device 10.

[Example of processing by in-vehicle wireless communication system 1]
FIG. 3 is a flowchart showing an example of processing by the in-vehicle wireless communication system 1 according to the present embodiment. For example, the process illustrated in FIG. 3 is performed when the user turns on the accessory power supply of the vehicle and the navigation device 10 is activated in conjunction with this, or when the user manually turns on the power of the navigation device. Be started.

  First, in the navigation device 10, the wireless communication unit 100 establishes a wireless communication connection with the smartphone 20 by Bluetooth (step S302). Next, the information acquisition unit 102 acquires the action history information of the user of the smartphone 20 wirelessly connected from the action history information storage unit 20c of the smartphone 20 (step S304). Furthermore, the preference estimation part 103 estimates a user's preference based on the action history information acquired at step S304 (step S306).

  Thereafter, in the smartphone 20, the first wireless communication unit 202a determines whether or not the received radio wave strength of the wireless communication connection (currently connected wireless communication connection) with the access point 30 by Wi-Fi has decreased below a predetermined value. Determination is made (step S308). Here, when it is determined that the received radio wave intensity has not decreased below the predetermined value (step S308: No), the first wireless communication unit 202a repeats the determination process of step S308.

  On the other hand, when it is determined that the received radio wave intensity has decreased to a predetermined value or less (step S308: Yes), the access point detection unit 201 detects the access point 30 installed around the vehicle (step S310). Then, the access point detection unit 201 transmits an access point list 600 indicating one or more access points 30 detected in step S310 to the navigation device 10 via wireless communication with the navigation device 10 using Bluetooth. (Step S312).

  In the navigation device 10, the access point selection unit 104 is a facility related to the user's preference estimated in step S306 from one or more access points 30 shown in the access point list 600 transmitted in step S312. The access point 30 installed in is selected (step S314). And the access point selection part 104 transmits the selection result of the access point 30 by step S314 to the smart phone 20 via the wireless communication with the smart phone 20 by Bluetooth (step S316). Based on the selection result, the first wireless communication unit 202a of the smartphone 20 establishes a wireless communication connection to the access point 30 selected in step S314 (step S318).

  Thereafter, when the distribution information receiving unit 203 of the smartphone 20 receives the distribution information from the access point 30 wirelessly connected in step S318 (step S320), the distribution information receiving unit 203 wirelessly communicates with the navigation device 10 using Bluetooth. This distribution information is transmitted to the navigation device 10 via communication (step S322). In the navigation device 10, the display control unit 105 causes the display 10a to display the distribution information transmitted in step S322 (step S324). Thereafter, the in-vehicle wireless communication system 1 ends the process illustrated in FIG.

[Example of processing by navigation device 10]
FIG. 4 is a flowchart illustrating an example of processing performed by the navigation device 10 according to the present embodiment. The process illustrated in FIG. 4 shows the process of step S324 shown in FIG. 3 more specifically.

  First, the display control unit 105 waits for distribution information to be transmitted from the smartphone 20 (step S402). Here, if the display control unit 105 does not receive distribution information (step S402: No), the display control unit 105 continues to wait for distribution information to be transmitted from the smartphone 20.

  On the other hand, when the display control unit 105 receives the distribution information (step S402: Yes), the entry availability determination unit 106 determines whether or not the current position of the vehicle is at a position where the vehicle can enter the facility from which the distribution information is distributed. Is determined (step S404). Here, when it is determined that the current position of the vehicle is in a position where the vehicle can enter the facility (step S404: Yes), the display control unit 105 displays the distribution information received in step S402 on the display 10a ( In step S406, the guidance information to the facility is displayed on the display 10a (step S408). Thereafter, the navigation device 10 ends the process illustrated in FIG.

[Access point 30 arrangement example]
FIG. 5 is a diagram illustrating an arrangement example of the access points 30 according to the present embodiment. FIG. 5 is a diagram schematically showing a map of roads 502a and 502b on which the vehicle travels and the surrounding area. In the example shown in FIG. 5, peripheral facilities 32a to 32d existing around roads 502a and 502b on which the vehicle travels are shown. Access points 30a, 30b, 30c, and 30d are installed in the peripheral facilities 32a, 32b, 32c, and 32d, respectively. The peripheral facilities 32a to 32d are configured to distribute distribution information related to the peripheral facilities from the corresponding access points 30a to 30d, respectively.

  For example, when the vehicle travels on the road 502a or the road 502b shown in FIG. 5, the access point detection unit 201 of the smartphone 20 detects each of the access points 30a to 30d installed around the vehicle. The access point list 600 (see FIG. 6) showing the access points 30a to 30d is generated. Then, the access point selection unit 104 of the navigation device 10 wirelessly selects the access point 30 installed in the peripheral facility that suits the user's preference from among the access points 30a to 30d shown in the access point list 600. The access point 30 is selected as the communication connection destination.

[Example of access point list]
FIG. 6 is a diagram showing an example of an access point list according to the present embodiment. An access point list 600 illustrated in FIG. 6 is an example of an access point list generated by the access point detection unit 201 of the smartphone 20. In this access point list 600, access point information 602a to 602d of the access points 30a to 30d (see FIG. 5) detected by the access point detection unit 201 is shown. Each of the access point information 602a to 602d includes the name of the facility where the access point 30 is installed and the received radio wave intensity (antenna bar). Among these, the facility name of the facility where the access point 30 is installed is an example of information with which the access point 30 can be specified.

  The access point list 600 is transmitted from the smartphone 20 to the navigation device 10 by wireless communication between the smartphone 20 and the navigation device 10 using Bluetooth. Then, the access point selection unit 104 of the navigation device 10 selects the access point 30 of the facility related to the user's preference from the four access points 30a to 30d shown in the access point list 600. It is selected as the access point 30 to be connected.

  For example, when the preference estimation unit 103 of the navigation device 10 estimates “automobile” as the user preference, the access point selection unit 104 selects the access points 30 a to 30 d shown in the access point list 600 from The access point 30 of the facility related to the automobile is selected as the access point 30 to be connected.

  For example, in the access point information 602a, the access point selection unit 104 selects the access point 30a in which the name “A car X town store” related to the car is set as the facility name of the facility where the access point 30 is installed. It selects as the 1st candidate of the access point 30 used as the connection destination of radio | wireless communication.

  In addition, the access point selection unit 104 selects an access point 30d in which, in the access point information 602d, the name “D automobile X town store” related to the automobile is set as the facility name of the facility where the access point 30 is installed. It selects as the 2nd candidate of the access point 30 of a connection destination.

  Then, the access point selection unit 104 selects either one of the access points 30a selected as the first candidate and the access point 30d selected as the second candidate based on a predetermined condition. 30 is selected as an access point 30 that is actually a connection destination of wireless communication. For example, when the condition is set so that the access point 30 with higher received radio wave strength is prioritized, the access point selecting unit 104 receives the received radio wave strength (intensity: strength :) of the access point 30a indicated in the access point information 602a. Weak) and the received radio wave intensity (intensity: medium) of the access point 30d indicated in the access point information 602d, the access point 30d is selected as the access point 30 that is actually the connection destination.

  In this way, when the access point selection unit 104 selects the access point 30 that is the connection destination of the wireless communication, the selection result is obtained from the navigation device 10 to the smartphone 20 by wireless communication between the navigation device 10 and the smartphone 20 by Bluetooth. Sent to. Then, the first wireless communication unit 202a of the smartphone 20 is connected to the selected access point 30 by wireless communication.

  In the present embodiment, when the received radio wave strength of the connected access point 30 decreases as the vehicle travels (for example, when the received radio wave strength is equal to or lower than a predetermined threshold), the access point detection unit 201 The point 30 is detected, and the latest access point list 600 is supplied to the access point selection unit 104. Then, the access point selection unit 104 selects an access point 30 as a new connection destination from one or more access points 30 shown in the latest access point list 600. Also at this time, the access point selection unit 104 preferentially selects the access point 30 related to the user's preference, as described above.

  In the above-described embodiment, the access point detection unit 201 may periodically detect the access points 30 installed around the vehicle (for example, every few seconds). In this case, the first wireless communication unit 202a newly sets the access point 30 of the facility related to the user's preference by the access point detection unit 201 even before the reception radio wave intensity of the connected access point 30 is reduced. If detected, the connection destination may be switched to the newly detected access point 30 at that timing. As a result, the distribution information distributed from the newly detected access point 30 can be received at a relatively early point in time, so that it is possible to guide to the facility where the access point 30 is installed early. become.

[Display example of distribution information and guidance information (first example)]
