[0033]
When the server 20 receives a request signal for providing information from the navigation device 1, the server 20 reads information from each of the databases 22 to 26 in accordance with the request, the user's preference and circumstances, and reads the read information. Is sent back to the navigation device 1. More specifically, the server 20 stores the personal data registered in the personality matching database 25 and the personal preference learning database 25a based on a request signal for information from the navigation device 1, as will be described in detail later. The guidance information suitable for the user's preference, circumstances, and the like is read from the map database 22 and the facility-related database 23 in consideration of the preference learning data, the regulation condition data stored in the regulation condition database 26, and the like.
[0034]
If there is no preference information on the guide information requested by the user in the personal preference learning database 25b of the user, the user's personal preference learning database 25b is used for the similarity determination data stored in the similarity determination database 25b. The similar characteristic person is searched, and the preference learning data stored in the personal characteristic learning database 25a of the similar characteristic person and the preference information specifically stored in the similarity judgment database 25b (for example, a specific facility Guidance information can be provided based on the name, etc.).
[0035]
The personality matching database 25 and the regulation condition database 26 connected to the server 20 will be described in detail below. First, the personal adaptation database 25 stores data for providing guidance information suitable for user preference information. As described above, personal data relating to authentication and preference of the user of the vehicle V, , An individual preference learning database 25a, a similarity determination database 25b, and the like. The personal data includes, in addition to the user authentication data, whether or not a toll road is used, the type of road to be selected, selection of which of the traveling time and traveling distance is to be prioritized, preference of facilities, and break time. Preference information relating to the user's preference, such as timing and a desired place for a break, is registered in advance.
[0036]
The personal preference learning database 25a stores information such as destinations, routes, and facilities that have been set by the user up to now, movement information (position information) actually moved, display settings of landmarks, narrow streets, and the like. It can be automatically stored as preference learning data (learning information). When the user needs guidance information or the like, the guidance information or the like is provided mainly based on the preference learning data stored in the personal preference learning database 25a. It is possible to provide information reflecting
[0037]
On the other hand, the similarity determination database 25b stores the preference information related to the guidance information required by the user in the personal preference learning database 25a, for example, when the guidance information of an area unfamiliar to the user is required. Considering the case where the information is not stored, the similarity determination data for searching for the similar characteristic person of the user is registered. As shown in FIG. 6, an example of the registration screen of the similarity determination data is shown. As the similarity determination data, a selection condition of guide information, information about an individual, information related to a vehicle, and the like can be registered. Specifically, the selection conditions for guidance information include the selection conditions for taxiways, toll roads, and parking lots, the level of guidance for branching roads, and the choice of avoiding traffic jams. Information about individuals includes gender, family, and so on. The composition, personality, hobbies, preferences of facilities used, food preferences, music preferences, and the like are registered. In the information related to the vehicle, a frequently used gas station, a contracted road service company, and an emphasis on fuel efficiency are registered. By registering these pieces of information in the similarity determination database 25b, if the preference information related to the guide information required by the user is not found in the personal preference learning database 25a, the similar characteristic person of the user is identified. It is possible to search and provide guidance information based on the preference learning data stored in the personal preference learning database 25a of the similar characteristic person.
[0038]
Here, by registering specific contents of taste in the similarity determination data of the similarity determination database 25b (for example, the name of a favorite ramen shop, the name of a favorite hot spring, etc.), Even if the preference information related to the necessary information is not found in the preference learning data stored in the personal preference learning database 25a of the similar traitor, the similarity determination data described in the similarity determination database 25b is not included in the similarity determination data. Information can be provided to the user based on the information. This makes it possible to provide guidance information suitable for the user's preference even when there is no preference information on the guidance information required by the user in the personal preference learning database 25a of the similar characteristic person.
[0039]
Whether or not to provide personal preference learning data and similarity determination data of another user when another user makes a similarity determination can be determined according to the will of the user. Therefore, the privacy of the user can be sufficiently protected.
[0040]
The regulation condition database 26 stores information to be provided to the user and regulation condition data for regulating the control of the vehicle V. As shown in an example of a registration screen of the regulation condition database 26 in FIG. 7, as regulation condition data, information of a user to be regulated, regulation conditions of guidance information, instructions for vehicle control, and the like are registered. Can be. Specifically, authentication information of the user to be registered is registered in the information on the user to be regulated, and restrictions on selection of roads and parking lots and restrictions on the use of facilities are registered in the regulation conditions of the guidance information. At the same time, it can be set so that hot springs, eating and drinking facilities and the like are provided with priority, and music information and baseball progress information are provided with priority. In addition, in the instruction for vehicle control, the driving state and use condition of the vehicle are set such as giving importance to fuel efficiency, limiting the vehicle speed to a predetermined speed or less (for example, 65 km / h or less), setting a high air-conditioning temperature, and the like. Can be set to control the condition. In addition, each regulation condition can be set for each user who is permitted to use the information in advance, or for each area where guidance information is provided.
[0041]
When the above-described restriction condition is stored in the restriction condition database 26, each user is identified by the authentication data stored in the restriction condition database 26, and guidance information to be provided to the user is provided. And the control of the vehicle V. That is, by registering the control conditions in the control condition database 26, the control is performed in consideration of the circumstances of the user when the driving technique is inexperienced or when the driver is unfamiliar with the area or the intention of the owner of the vehicle V. Therefore, the convenience and safety of the occupant of the vehicle can be improved, and the intention of the owner of the vehicle V can be reflected in the usage state of the vehicle V.
[0042]
Note that the regulation conditions registered in the regulation condition database 26 can be set for each condition such as time range designation and region designation for designating a time range and a region. May be set or the regulation may be relaxed or canceled if the owner of the vehicle is riding in the same vehicle.
[0043]
Although not shown in detail, the owner communication terminal 3 includes at least a display unit for displaying various information, an input unit for the owner or the like to perform an input operation, and various units connected to the display unit and the input unit. And a communication unit that performs communication with the Internet line 6 and the wireless communication antenna 7. The owner communication terminal 3 has a browser function. A request to provide information to the server 20 of the information center 2 using the browser function, and a display of information provided from the server 20 on the display unit, are performed. It is possible. The owner communication terminal 3 may be a personal computer 31 installed at the owner's home or the like, or a mobile terminal 32 such as a mobile phone or a PDA.
[0044]
(Operation of navigation system)
An example of the operation flow of the navigation system A is shown in FIG. 5 and will be described in detail below. In the navigation system A according to the present embodiment, first, in step SA1, the owner or the like of the vehicle V inputs the personal data of the user and the regulation conditions corresponding to the user to the owner communication terminal 3, and connects the Internet line 6 Via the server 20 of the information center 2 via the Internet. Specifically, the server 20 stores user authentication data and information on preferences in the personal matching database 25 as personal data, and stores similarity determination data necessary for performing similarity information search in the similarity determination database 25b. The information to be provided to the user and the conditions for controlling the control of the vehicle V are registered in the restriction condition database 26.
[0045]
Here, the server 20 that registers the regulation conditions as shown in FIG. 7 in the regulation condition database 26 in step SA1 is the regulation condition setting means.
[0046]
Next, in step SA2, when the user gets on the vehicle V, the personal authentication reading device 18 provided in the navigation device 1 of the vehicle V reads the authentication signal of the user. The authentication signal is input to the server 20 of the information center 2 via the wireless communication antenna 7 and the Internet line 6. The personal authentication reading device 18 may be any device that can read a user's authentication signal, such as a device using Bluetooth, a device for directly inputting a fingerprint collation, a personal ID card, or an authentication number.
[0047]
In the following step SA3, the user authentication signal input to the server 20 in step SA2 is compared with the authentication data registered in the personal matching database 25 of the server 20. Then, the personal data, the preference learning data, and the regulation condition data regarding the authenticated user are transmitted to the navigation device 1 of the vehicle V. Specifically, the server 20 learns user's preference information (for example, used route and facility) from the personalized database 25 using personal data including information on the authenticated user's preference. The stored preference learning data is retrieved from the personal preference learning database 25a, and the data on the regulation conditions set by the owner or the like of the vehicle V from the regulation condition database 26, and transmitted to the navigation device 1 of the vehicle V.
[0048]
Here, in steps SA2 and SA3, the server 20 that authenticates that the user's authentication signal read by the personal authentication reading device 18 of the vehicle V matches the authentication data stored in the personal matching database 25 is authenticated. Corresponding to the means. Note that the authentication unit may be the navigation device 1 of the vehicle V. That is, the authentication data may be stored in the navigation device 1 of the vehicle V and authentication may be performed by the navigation device 1.
[0049]
Each data transmitted to the navigation device 1 of the vehicle V in step SA3 is temporarily stored in the storage device 17 of the navigation device 1 in step SA4, and in the subsequent step SA5, the regulation stored in the storage device 17 is controlled. Based on the condition data, the controller 10 of the navigation device 1 sets conditions of a control unit (driving control unit) (not shown) that controls the traveling speed of the vehicle V, for example, upper limit of traveling speed, temperature setting of air conditioning, and the like. And so on. This makes it possible to regulate the control of the vehicle V based on the regulation conditions set by the owner or the like of the vehicle V, and the intention of the owner or the like can be reflected in the usage status of the vehicle V.
[0050]
Next, in step SA6, when the user inputs a request for guidance information to the navigation device 1, a request signal is transmitted to the server 20 of the information center 2 via the wireless communication antenna 7 and the Internet line 6. Then, the server 20 considers the personal data and the preference learning data, determines a route to the destination, guidance information, and the like in consideration of the regulation condition data, and starts providing information to the user. Specifically, as shown in the flow of FIG. 8 described later, when the preference information on the guide information required by the user is in the personal preference learning database 25a, the guidance provided to the user based on the preference information. Information is determined. On the other hand, if the preference information does not exist in the personal preference learning database 25a, a similar characteristic person of the user is searched by the similarity determination data of the similarity determination database 25b, and based on the similar characteristic person's preference learning data. Guidance information to be provided to the user is determined. When the preference learning data of the similar characteristic person is used as described above, the guide information is determined in consideration of the preference information registered in the user's personal data.
[0051]
When the regulation condition is set for the user by the owner or the like of the vehicle V, the guidance information determined by the preference learning data of the user or the similar characteristic person as described above is stored in the regulation condition database 26. It is regulated by the stored regulation condition data. Specifically, the contents to be regulated are those previously input by the vehicle owner or the like on the regulation condition data registration screen as shown in FIG. 7 described above. You can do so.
[0052]
Therefore, in step SA6, guidance information suitable for the user's preference can be provided by providing the guidance information based on the personal data and the preference learning data of the user and the similar characteristic person. In addition, the owner of the vehicle or the like sets restrictions on the guide information according to the circumstances of the user (for example, the driving skill is inexperienced, or the user is unfamiliar with the area). Since guidance information can be provided, convenience and safety can be improved, and the intention of the vehicle owner or the like can be reflected in the usage status of the vehicle.
[0053]
It should be noted that in the search for the similar characteristic person as described above, not only when one user is in the vehicle but also when there is a passenger in the vehicle, the configuration of the occupant in the vehicle, that is, when the occupant is 4 By registering several types of preference information in advance in the similarity determination database 25b according to a family or a lover, it is possible to search for a similar characteristic person according to the structure of the occupant.
[0054]
Further, as described above, when there is no learning preference data of the user, that is, in an area where the user is not guided, guidance information based on the preference learning data of the similar characteristic person is automatically provided. However, the present invention is not limited to this, and it is also possible not to provide guidance information based on the preference learning data of the similar characteristic person by manual operation, or to select the type of guidance information to be provided.
[0055]
Further, as described above, when considering the regulation condition data stored in the regulation condition database 26, the server 20 presents several types of routes other than the recommended route to the user, and gives the user a plurality of routes. You may make it select from routes. Specifically, as shown in FIG. 9, the C route that meets the regulation conditions is the recommended route, but the A route that is short even if the road is narrow and the B route that runs on a mountain road are also determined by the user. You can choose. When the user selects a route other than the recommended route, a warning may be issued to the user, or the permission of the owner or the like who has input the restriction condition may be obtained.
[0056]
In step SA6, first, guide information is determined based on personal data and preference learning data of a user and a similar characteristic person, and then regulation conditions are taken into consideration. However, the present invention is not limited to this. After the information is regulated by the regulation condition data, guidance information may be provided based on personal data or preference learning data of the user or similar characteristic person.
[0057]
Here, the server 20 that searches for another similar person (similar characteristic person) having a similar preference to the user based on the similarity determination data stored in the similarity determination database 25b is used as a preference similarity search unit. The server 20 that searches for guide information suitable for the user's preference in accordance with the flow of FIG. 8 and provides the search result to the user is provided to the information providing means, and the server 20 that regulates the guide information to be provided to the user based on the restriction condition data is provided. Each corresponds to a regulatory measure.
[0058]
Next, at step SA7, the user is notified of the guidance information to be provided to the user, the contents of the regulation conditions relating to vehicle control, and the setters who set the regulation conditions. For example, as shown in FIG. 10, when there is a situation that violates the regulation condition in the middle of the route selected by the user, it is possible to notify the user of the content of the regulation condition and the setter of the regulation condition. it can. As a result, the user can eliminate doubts and discomfort regarding the provided guidance information and vehicle control. Here, the navigation device 1 for notifying the user that the guidance information provided to the user is set with the restriction condition and the setter of the restriction condition or the like corresponds to the notification means.
[0059]
In the subsequent step SA8, the user preference information based on the movement history of the vehicle V and the like is automatically stored in the personal preference learning database 25a of the server 20 of the information center 2 via the wireless communication antenna 7 and the Internet line 6. . The stored information is then used as preference learning data when selecting a route to the destination or searching for guidance information to be provided. As a result, the user's behavior patterns and preferences when using the navigation system A can be stored in the information center 2 and the data can be reflected in future information provision. Therefore, it is possible to provide more appropriate information to the user.
[0060]
Further, in step SA9, it is determined whether or not the travel information such as the movement history and the travel speed of the running vehicle V matches the regulation condition data stored in the storage device 17 of the navigation device 1 of the vehicle V. If this determination is YES (the traveling information of the vehicle matches the regulation condition data), the determination of step SA9 is repeatedly performed based on the obtained traveling information. On the other hand, if NO (the traveling information of the vehicle does not match the regulation condition data), the process proceeds to step SA10 to issue an alarm to the user and notify the server 20 of the information center 2 as well. As a result, the data at the time of the restriction condition violation is stored in the restriction condition database 26 of the server 20, and a notification is also sent to the owner communication terminal 3.

(Decision of guidance information reflecting user preferences)
The procedure for determining the guide information reflecting the user's preference performed in step SA6 will be described in detail below based on the flow of FIG. First, when a request signal such as a destination and guidance information is input to the server 20 by the user, the flow starts, and in step SB1, the information input to the server 20 (a destination required by the user, It is determined whether or not the preference information related to the guide information is stored in the personal preference learning database 25a of the user. If this determination is YES (the preference information related to the input information is stored in the personal preference learning database 25a), the process proceeds to Step SB2, and the server 20 performs the processing based on the data stored in the personal preference learning database 25a. Determine the guidance information. On the other hand, if NO in step SB1 (the preference information related to the input information is not stored in the personal preference learning database 25a), the process proceeds to step SB3, where the similarity stored in the similarity determination database 25b is stored. Based on the judgment data, a similar characteristic person of the user is searched. Then, the server 20 determines the guide information in consideration of the preference information stored in the personal preference learning database 25a of the similar characteristic person and the personal data registered in the user's personal suitability database 25.
[0062]
Specifically, in step SB2, based on the user preference learning data stored in the personal preference learning database 25a, a road with a high frequency of travel or a facility with a high frequency of use is preferentially selected, By adjusting the level of display of marks, roads, etc., the frequency of use of toll roads, the preference of parking lots, etc. according to the lifestyle and preferences of the user, it is possible to provide information suitable for the preferences of the user. .
[0063]
In step SB3, based on the similarity determination data stored in the similarity determination database 25b of the user, a similar characteristic person whose lifestyle and taste are similar to the user is searched. By taking into account the preference learning data of the similar traitor, it is possible to select a road where the similar traitor has a high frequency of travel or a facility with a high use frequency, or to provide a traffic congestion avoidance route where the similar traitor has a high frequency of use. In addition, by considering the user's preference registered in the user's personal data in the information, information closer to the user's preference can be provided.
[0064]
After providing information in step SB2 or SB3, the process proceeds to step SB4 to determine whether a new information request has been input. If the determination is YES (a new information request has been input), the process returns to step SB1. If NO (a new information request has not been input), the flow in FIG. 8 ends.
[0065]
According to the above flow, if the preference information on the information required by the user is in the user's preference learning data, guidance information is provided based on the information. Since guidance information can be provided based on the preference learning data of the characteristic person, guidance information reflecting the user's preference can be provided to the user. Thereby, the convenience of the user can be improved.
[0066]
Therefore, according to the above-described embodiment, in the navigation system that provides guidance information to the user, the owner or the like of the vehicle V regulates the guidance information to be provided to the user by setting the restriction conditions in advance, Since the control instruction is given, guide information suitable for the user's circumstances (driving skill, presence / absence of intuition, etc.) can be provided, and the owner can control the running state of the vehicle. . As a result, the safety of the occupant of the vehicle and the vehicle can be improved, and the intention of the owner or the like can be reflected on the usage status of the vehicle.
