  According to the present invention, the user preference information is created by the preference information creation unit based on the characteristics of the content reproduced by the navigation device. Here, for example, when music content is being played back, the content characteristics correspond to music genres (rock, country, pop, classic, etc.), and the preference information creation unit is assumed from the music genre. Preference information reflecting the preference of the user (listener) (moving at a fast driving pace if locked, moving at a slow driving pace while enjoying scenery in a country, etc.) is created. And such a user's preference is assumed to influence the travel pace at the time of a user driving a vehicle.

  Therefore, the server determines a route to the destination based on the current position and destination of the navigation device and the user preference information, and transmits information on the determined route to the navigation device. Thereby, since a common route is determined for users having the same preference, each user (driver) driving the vehicle using the navigation device is assigned to a route according to his own preference difference. . As a result, the travel pace of the vehicles traveling on the same route is made uniform and it becomes difficult for traffic jams to occur, so that the possibility of stress caused by traffic jams to the user can be reduced. Even if a traffic jam occurs, the user is driving on a road that matches his / her preference (a road with a good scenery, a road with many shops along the road, etc.), and therefore it can be expected that stress is less likely to occur.

  According to the present invention, the preference information creating step creates user preference information based on the characteristics of the content being played back by the navigation device. In the route search condition transmission step, the navigation device transmits information on the current position and the destination of the navigation device to the server. Further, in the determined route transmission step, the server determines a route to the destination based on the current position and destination of the navigation device and user preference information, and transmits the determined route information to the navigation device. . Thereby, a common route is determined for users having the same preference, and each user (driver) driving the vehicle using the navigation device is assigned to a common route according to the difference in preference. As a result, the travel pace of the vehicles traveling on the same route is made uniform and it becomes difficult for traffic jams to occur, so that the possibility of stress caused by traffic jams to the user can be reduced. Further, even if a traffic jam occurs, the user is traveling on a road that matches his / her preference (good scenery, many roadside shops, etc.), so it can be expected that stress is less likely to occur.

Next, the navigation apparatus of the present invention
A communication unit that communicates with a server that provides route information;
A current position detector for detecting the current position;
A destination reception unit for receiving a destination input by a user;

  The route information acquisition unit 21 transmits the current position information and destination information of the vehicle 1 and the information of the music being played back by the music playback unit 17 to the server 50 to request route information to the destination. The route information determined by the server 50 in response to this request is received from the server 50.

  Next, referring to FIG. 3, the server 50 includes a communication unit 51, a storage unit 52, and a server control unit 60.

  The communication unit 51 has a function of performing communication with the navigation device 10 and the mobile terminal 30 through the communication network 2 such as the Internet.

  The storage unit 52 is divided into various areas, and the content area 70 holds information distributed to communication terminals such as the navigation device 10 and the mobile terminal 30. Specifically, there are music data 71 that is music content, narration data 72 that is content of disc jockey narration about sightseeing information and current topics, and video data 73 that is content such as photos and videos. Is retained.

  In the user information area 80, a user ID 82 uniquely assigned to a user registered in the operation site of the server 50 (P which is a user of the navigation device 10 in this embodiment), a user profile 83, and the user's A user information block 81 (81a, 81b, 81c,...) Configured by associating the preference information 84 is held for each user.

  The user profile 83 holds information on the user profile (gender, age, hobbies, etc.) input at the time of registration in the operation site of the server 50 or subsequent correction.

  The preference information 84 is created based on points obtained by applying the genre of music reproduced by the navigation device 10 (corresponding to the characteristics of the content of the present invention) to the preference information correspondence table 85 shown in FIG. The The preference information correspondence table 85 includes a music genre of a first genre (blues, jazz, classical music, folk), a second genre (rock, alternative, heavy metal), a third genre (country, movie soundtrack, pops), And the fourth genre (hip hop, soul, funk, electronica), and set the points (weighting) of the road driving environment (low signal, maximum speed, scenery, number of stores along the road) for each genre. Yes.

  For example, it is assumed that a user (driver) listening to music of the first genre drives at a slow running pace because he likes a relatively slow-paced song. Therefore, for the first genre, “Scenery” is assigned 5 as the highest point, and “Store” is assigned 4 as the next point. Further, 2 is assigned to “low signal”, and 1 which is the lowest point is assigned to “maximum speed”.

  Therefore, for users who listen to music of the first genre, a route with good “scenery” and a lot of “stores” along the road has priority over a route with few “signals” and a high “maximum speed”. To be searched.

  Further, it is assumed that the user (driver) listening to the music of the second genre travels at a fast pace because he likes an upbeat and high-tempo song. Therefore, for the second genre, 5 which is the highest point is assigned to “highest speed” and “low signal”, and 1 which is the lowest point is assigned to “landscape” and “number of stores”.

  Therefore, for users who are listening to music of the second genre, the route with the highest "highest speed" and "low signal" takes precedence over the route with good "scenery" and the route with many "stores". To be searched.

  In this way, by using the user preference information created with reference to the preference information correspondence table 85, a route assumed to match the user preference assumed from the genre of music listened to by the user (driver) is obtained. Can be determined.

  In the navigation area 90, traffic information data 91, map data 92, and store information data 93 are held.

  The server control unit 60 is an electronic circuit unit including a CPU, a memory, an interface circuit, and the like (not shown), and the server 50 overall is executed by executing a control program for the server 50 held in the memory by the CPU. Functions as a route search reception unit 61, a preference information creation unit 62, and a route determination unit 63. Processing by the route search reception unit 61, the preference information creation unit 62, and the route determination unit 63 will be described later.

  Next, according to the flowchart shown in FIG. 5, in response to a search request from the navigation device 10, the server 50 determines a route to the destination and transmits information on the determined route to the navigation device 10. explain.

  The route information acquisition unit 21 of the navigation device 10 receives a destination input operation and a route search instruction from the user P by the input unit 16, and the mobile phone network wireless communication unit 13b Route search instruction data including information on the current position and destination and information on music being played by the music playback unit 17 (corresponding to information on the content of the present invention, such as a song name, artist name, etc.) are stored in the server 50. Transmit (corresponding to the route search condition transmitting step in the navigation method of the present invention).

  When the server 50 receives the route search instruction data from the navigation device 10 in STEP1 of FIG. STEP 1 to STEP 2 are processes performed by the route search reception unit 61.

  The route search reception unit 61 proceeds to STEP 2 when receiving the route search instruction data in STEP 1, and the navigation device 10 current position (current position of the vehicle 1) and destination information included in the route search instruction data, and navigation Information on music being played back by the apparatus 10 is acquired.

  The subsequent STEP 3 is processing by the preference information creation unit 62 (corresponding to the preference information creation step in the navigation method of the present invention). The preference information creation unit 62 determines from the music information whether the music being played corresponds to the above-described first genre to fourth genre. This determination may be made by accessing another server having a database in which song titles and genres are associated with each other.

  Then, as described above, the preference information creation unit 62 creates the user preference information 84 by applying the genre of the song being played back by the navigation device 10 to the preference information correspondence table 85 shown in FIG. And stored in the user information block 81 of the user information area 80. Note that the user preference information 84 may be created based on music history information that has been played before, instead of or in addition to the music that is played on the navigation device 10.

  In addition to the user preference information 84, the route may be determined in consideration of the information of the user profile 83. For example, when it is recorded in the user profile 83 that the hobby is eating, a route with a local restaurant along the line may be selected.

  Subsequent STEP4 to STEP5 are processing by the route determination unit 63 (corresponding to the determined route transmission step in the navigation method of the present invention). As described above, the route determining unit 63 refers to the traffic information data 91, the map data 92, and the store information data 93 based on the preference information 84 of the user P and determines a route to the destination. Then, in the next STEP 5, the route determination unit transmits information on the determined route to the navigation device 10.

  In the navigation device 10, the route information transmitted from the server 50 is acquired by the route information acquisition unit 21, and the route guidance to the destination is obtained by the navigation unit 18 based on the user preference determined by the server 50. Is started.

  The next STEP 6 to STEP 8 are processes by the preference information creation unit 62. The preference information creation unit 62 receives the information of the music being played transmitted from the navigation device 10 at STEP 6 as needed, and whether or not the music has been changed at STEP 7 (whether or not the music has been changed by the user P selection operation). ).

  When the music is changed, the process proceeds to STEP 8, where the current position information is acquired from the navigation device 10 and the process returns to STEP 3. Thus, the user preference information 84 is updated based on the changed music genre, and the route to the destination is re-searched in STEP4.

  On the other hand, when the music reproduced by the navigation device 10 is not changed, the process returns from STEP 7 to STEP 5, and in this case, the preference information 84 of the user P is not updated.

  With the process of FIG. 5, the route information determined based on the preference of the user (driver) P is transmitted to the navigation device 10.

  And the information of the route determined based on each user's preference is provided also to the navigation apparatus 10 of the other user registered into the operation site of the server 50. Therefore, as shown in FIG. 6, the route from the current position 100 to the destination 110 of the vehicle 1 equipped with the navigation device 10 has a preference in the first genre shown in FIG. 4 based on each user's preference. For a certain user, a route R1 with a good scenery and a slow car flow is determined.

  For users who have a preference for the second genre, a toll road R2 with a fast car flow is determined. In addition, for a user who has a preference for the third genre, a route R3 with a large number of stores along the road is determined.

  Thus, by determining the route according to the preference of the driver, vehicles having a relatively slow traveling pace gather on the route R1, and vehicles having a relatively fast traveling pace gather on the route R2. Therefore, the traveling pace of vehicles traveling on each route is made uniform, and it becomes difficult for traffic jams to occur. Therefore, the possibility of causing stress to the user due to traffic jams can be reduced.

  Moreover, even if a traffic jam occurs, each vehicle 1 travels on a route that matches the user's preference, so that it can be relaxed by enjoying the scenery, dropping in at a store, etc., so that it is difficult for the user to be stressed. Can be expected.

[Modification 1]
In the above embodiment, the preference information creation unit 62 is provided in the server 50, but may be provided in the navigation device 10. In this case, the navigation control unit 20 of the navigation device 10 functions as the preference information creation unit 62, and the preference information creation unit 62 uses the preference information correspondence table 85 held in the storage unit 12 or the server 50 to perform music. User preference information is created based on the genre of music being played back by the playback unit 17.

  Then, by transmitting user preference information from the navigation device 10 to the server, the route determination unit 63 of the server 50 determines a route to the destination based on the preference information.

[Modification 2]
In the present embodiment, the navigation device 10 that is provided in the vehicle 1 and performs route guidance of the vehicle 1 is shown. However, the navigation device is configured by a portable navigation device carried by a pedestrian or an application of a mobile terminal such as a smartphone. Thus, the present invention can also be applied when guiding a walking route of a pedestrian. In this case, since pedestrians with common preferences walk the same route at the same pace, it is difficult for stress to occur, and it is expected that exchange between pedestrians is promoted.

[Modification 3]
In the above embodiment, music is shown as the content to be played back by the navigation device 10, but any content that can be used to determine the user's preference may be used, so that the preference information depends on the playback status of other content such as images, video, and narration. You may make it create.
