The microphone 113 outputs a voice signal to the voice processing circuit 151, and the voice processing circuit 151 converts the signal input from the microphone 113 into digital data and outputs the signal to the processing unit 130.
The voice processing circuit 151 outputs a voice signal to the speaker 115 based on the digital voice data output by the processing unit 130, and causes the speaker 115 to output sound.

Further, the navigation device 120 may include a communication unit 153. The communication unit 153 is a communication module that executes wireless communication conforming to communication standards such as a mobile phone network, Wi-Fi (registered trademark), and Bluetooth (registered trademark). The communication unit 153 transmits and receives various data to and from the device installed in the vehicle interior 10 or the device outside the vehicle 1 under the control of the processing unit 130.

The processing unit 130 is, for example, a computer including a processor such as a CPU (Central Processing Unit). A storage unit 140 is connected to the processing unit 130. The storage unit 140 stores the control program, which is a computer program executed by the processing unit 130, and various data processed by the processing unit 130 so that the processing unit 130 can read the control program.

The hardware constituting the processing unit 130 and the storage unit 140 is not limited to a specific aspect. For example, the processing unit 130 may be composed of a single processor. Further, the processing unit 130 may be a device in which a processor, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like are integrated. The storage unit 140 may be composed of a non-volatile storage device that non-volatilely stores programs and data, and specifically, may include a magnetic storage device such as a hard disk and a semiconductor storage device such as a flash ROM. Good. Further, the storage unit 140 may include a volatile storage device that temporarily stores programs, data, and the like executed by the processing unit 130. Further, the processing unit 130 and the storage unit 140 may be one integrated device.

The processing unit 130 controls each unit of the navigation device 120 based on the data stored in the storage unit 140 by executing the program stored in the storage unit 140.
The processing unit 130 is an operation reception unit 131, a voice recognition unit 132, a display control unit 133, a user identification unit 134, a guidance information generation unit 135, a notification unit 136, a notification control unit 137, and a user as functional elements or functional units. A model generation unit 138 is provided. These functional elements included in the processing unit 130 are realized by the processing unit 130, which is a computer, executing a control program stored in the storage unit 140.
The control program executed by the processing unit 130 can be stored in any computer-readable storage medium. Alternatively, all or part of the functional elements included in the processing unit 130 may be configured by hardware including one or more electronic circuit components.

The storage unit 140 stores a map DB (database) 141, a route DB 142, a voice recognition DB 143, a user model data storage unit 144, and a history storage unit 145 as a database that uses the storage area of the storage unit 140.

The map DB 141 and the route DB 142 are databases that store data for navigation. Map DB 141 stores map data. The route DB 142 stores data used when determining the route of the vehicle 1, such as information indicating a road on which a vehicle including the vehicle 1 can travel, information indicating a congestion occurrence probability and a congestion occurrence status, and information on traffic regulation. To do.

Further, the map DB 141 includes information on a POI (Point Of Interest) regarding a road on which the vehicle 1 can travel. Specifically, POIs are geographical landmarks, commercial facilities, public facilities, restaurants, other installations, and the like. The map DB 141 stores the POI position information and the POI type and name in association with each other.

The voice recognition DB 143 stores data for recognizing the voice data output by the voice processing circuit 151 as a voice command. The voice recognition DB 143 includes, for example, voice commands that can be used by the navigation device 120 and data that identifies the voice that the navigation device 120 recognizes as voice commands. As the data for identifying the voice, for example, a voice feature amount extracted from the frequency component of the voice data, a change in the volume level, and the like can be used, but other data may be used. Further, the voice recognition DB 143 may include dictionary data for recognizing voice data as text and text data of voice commands. In this case, the voice recognition DB 143 can be used as data for converting the voice collected by the microphone 113 into text and recognizing it as a voice command based on the text data.

The user model data storage unit 144 stores the user model setting data 161, the guidance scenario, and the user model data 167, which will be described later.
The history storage unit 145 stores the history information described later.

The operation receiving unit 131 acquires the operation content of the user U by detecting the contact operation of the user U with respect to the touch sensor 103 and specifying the operation position.
The voice recognition unit 132 analyzes the digital voice data output by the voice processing circuit 151 based on the voice signal output by the microphone 113, and recognizes the content spoken by a human from the voice collected by the microphone 113. The voice recognition unit 132 performs frequency analysis of the voice data output by the voice processing circuit 151, calculates a voice feature amount, and refers to the voice recognition DB 143 based on the calculated voice feature amount to obtain the collected voice. Determine the presence or absence of the corresponding voice command and identify the voice command. The voice recognition unit 132 recognizes the content of the utterance when, for example, the user U utters an instruction to the navigation device 120.

The display control unit 133 outputs a display signal to the display 101 to display various screens including images and characters.

The user identification unit 134 has a function of specifying the user U who operates the navigation device 120. The user identification unit 134 corresponds to an example of the passenger identification unit of the present invention.

The guidance information generation unit 135 determines the route on which the vehicle 1 travels when executing the navigation operation of the vehicle 1. For example, the guidance information generation unit 135 specifies the position of a destination, a waypoint, a departure place, or the like designated by the operation of the user U. The guidance information generation unit 135 refers to the data of the map DB 141 and the route DB 142, and determines the route for the vehicle 1 to reach the destination from the departure place or the current position.

Further, the guidance information generation unit 135 generates guidance information for driving the vehicle 1 along the determined route of the vehicle 1. The guidance information generation unit 135 generates display data for displaying the navigation screen displayed on the display 101 as the guidance information visually provided.

The guidance information generation unit 135 generates a message for guiding the operation of the vehicle 1 in natural language as the guidance information audibly notified by the speaker 115. The guidance information generation unit 135 determines the number of times and the timing of outputting a message.

The message generated by the guidance information generation unit 135 corresponds to a point on the route of the vehicle 1. For example, the guidance information generation unit 135 generates messages instructing operations such as going straight, turning right, and turning left of the vehicle 1, and these operations are operations executed at specific points in the route of the vehicle 1. The point that is the target of the guidance information is called the guidance point in the following explanation. The guide point corresponds to an example of the notification position of the present invention. For example, when transmitting guidance information including an instruction to turn the vehicle 1 to the right at an intersection, this intersection corresponds to a guidance point.
The navigation device 120 notifies the guidance information corresponding to the guidance point. That is, the navigation device 120 notifies the guidance information while the vehicle 1 is located in front of the guidance point on the route and approaches the guidance point.

The navigation device 120 makes one or a plurality of notifications for one guide point. For example, the navigation device 120 provides guidance information for instructing a right turn at an intersection when the vehicle 1 reaches 1000 m before the intersection, 600 m before, 300 m before, and 100 m before. Notify when.
The guidance information generation unit 135 specifies a timing for performing notification when generating guidance information. The timing of notification is defined by, for example, the distance between the vehicle 1 and the guide point.

It is desirable to adjust the number of times of notification for one guide point according to the proficiency level of the user U. For example, if the number of notifications is large, there is no problem even if the voice of the notification is missed, so that the user U who is unfamiliar with the route is highly satisfied. On the other hand, when the user U is familiar with the route, if the number of notifications is large, the user U may feel the notification complicated, and the satisfaction level with the navigation may decrease.
The same can be said about the timing of notification and the amount of information provided at the time of notification.

The navigation device 120 utilizes a user model so that the user U can be notified at a frequency suitable for the user U. The user model is a virtual model that reflects the degree to which the user U who operates the vehicle 1 needs navigation of the navigation device 120. For example, a user model who is unfamiliar with directions is set with a user model having a high degree of need for navigation, and a user U who is familiar with directions is set with a user model with a low degree of needing navigation. If the navigation device 120 sets the notification state and the content of the guidance information to be notified to the user U according to the user model, the navigation device 120 can perform the notification suitable for the proficiency level of the user U, and the user U has a high degree of satisfaction. Can be obtained.

In the present embodiment, the navigation device 120 executes a notification adjustment process for changing the content of the guidance information and the notification state, targeting the guidance information to be notified by voice from the speaker 115, corresponding to the user model. Specifically, the content of the guidance information is the type and amount of information to be notified. The amount of information can be rephrased as the detail of information. Further, the notification state is specifically the timing and the number of notifications.

FIG. 3 is a diagram showing a setting example of the user model and the notification content, and shows a configuration example of the user model setting data 161 that defines the notification content for each user model. In the example of FIG. 3, the timing of notification is defined by the distance between the guide point and the vehicle 1. In addition, the degree to which the user model requires navigation is expressed as the navigation utilization.

Using the user model setting data 161 of FIG. 3, three types of user models A, B, and C can be set. The user model A is a model assuming a user U having a high degree of navigation usage, such as a user U who is unguided to directions. The timing of notification is determined to be five times, including 1000 m before, 600 m before, 300 m before, 100 m before, and 0 m before the guide point. Here, 0 m represents the timing at which the vehicle 1 reaches the guide point.
The user model C is a model assuming a user U having a low navigation usage such as a user U who is proficient in directions, and the timing of performing notification is less than that of the user model A. The user model B is a model assuming a user U having a standard navigation usage. The user model B is used, for example, as the default user model.
The notification timing shown in FIG. 3 is information that determines both the notification timing and the number of notifications.

The user model setting data 161 defines the content of the guidance information in association with the user model. For example, it is specified that the amount of guidance information is increased for the user model A, the amount of information is decreased for the user model C, and the amount of information is standard for the user model B. Will be done.

In this way, in the navigation device 120, a plurality of user models having different navigation usages are set, and the number of notifications, the notification timing, and the contents of the guidance information are set in association with each user model. The user model setting data 161 is stored in, for example, the user model data storage unit 144.

FIG. 3 is only one setting example, and the content of the user model setting data 161 can be changed as appropriate. For example, the user model setting data 161 may be information for setting only the number of notifications for each user model. In this case, the notification timing may be automatically determined according to the set number of notifications. Further, the notification timing may be set in advance in association with the number of notifications by setting data different from the user model setting data 161.
Further, the user model setting data 161 may be data that does not include the notification timing and the number of notifications and sets the content of the guidance information for each user model. In this case, for the number of notifications and the timing of notification, for example, one pattern common to all user models is applied.

FIG. 4 shows an example of guidance information generated based on the user model.
The navigation device 120 generates guidance information in a scenario format in which the information for specifying the timing of notification and the content of the guidance information are associated with each other. This guidance information will be referred to as a guidance scenario below. In the present embodiment, a guidance scenario regarding guidance information notified by voice is generated.

In FIG. 4, the guidance scenario 163 generated by the guidance information generation unit 135 corresponding to the user model A is indicated by reference numeral A. Further, the guidance scenario 165 generated by the guidance information generation unit 135 corresponding to the user model C is indicated by reference numeral B.

The guidance scenarios 163 and 165 include the notification timing and the content of the guidance information, and further include the position information of the guidance point.
In the guidance scenario 163, the number of notifications is large and the amount of guidance information is large. In the example of FIG. 4, the guidance information is Part. It is composed of three pieces of information, A, B, and C. A is information indicating the distance between the current position of the vehicle 1 and the guide point, and is described in Part. C is information instructing the operation of the vehicle 1. Part. B is information that informs a landmark that serves as a guide for guidance points. Part. It can be said that A and C are essential information. On the other hand, Part. B is auxiliary information. Guidance scenario 163 is described in Part. Since it contains all the information of A, B, and C, it is suitable for the user U who has little prior knowledge or experience regarding the guide point.

In the guidance scenario 165, the number of notifications is small and the amount of information included in the guidance information is small. Guidance scenario 165 is suitable for user U, who does not need detailed guidance regarding the guidance point and has low navigation utilization.

The navigation device 120 identifies the user U by the user identification unit 134. The user identification unit 134 personally identifies the user U who operates the vehicle 1. In the present embodiment, a user ID is assigned to each user U as identification information that can identify an individual. When the user U operates the navigation device 120, the user identification unit 134 identifies the user U and identifies the user ID. The identification information of the user U is not limited to the user ID, and the name, nickname, or other information of the user U may be used.

In the navigation device 120, one user model may be set in association with one user U. For example, one user model may be set in association with one user ID. Further, a plurality of user models may be set in association with one user U. For example, it is conceivable to apply different user models depending on whether the vehicle 1 travels in an area or road where the user U has detailed knowledge and when the vehicle 1 travels in an area where the user U is unguided. ..

FIG. 5 is a diagram showing an example of user model data 167. The user model data 167 is data for setting a user model for each user ID, and is stored in the user model data storage unit 144. The user model data 167 may associate one user model with one user ID. Further, as shown in FIG. 5, a plurality of user models may be associated with one user ID.

In the example of FIG. 5, a user model is set for each location for one user ID. For example, for the user ID "0001", a user model corresponding to each of the four regions is set.

In general, car drivers tend to be familiar with directions in areas with many driving opportunities and unfamiliar with directions in areas with few driving opportunities. Areas with many driving opportunities are, for example, areas including places of residence, places of employment, commuting routes, and the like. Therefore, by setting the user model for each area, it is possible to perform notification suitable for the user U in each of the area where the user U is unfamiliar and the area where the user U knows in detail. In the user model data 167 of FIG. 5, the user ID “0001” is associated with the user model C having low navigation utilization in the “region 1” including the place of residence and the “region 2” including the place of work.

FIG. 6 is an explanatory diagram showing an application example of the user model data 167. FIG. 6 shows a point H1 where the user U lives and a point H2 where the user U works on the map. In the figure, the route P indicates the commuting route of the user U. Areas C1, C2, and C3 indicate administrative divisions and correspond to cities, towns, villages, counties, prefectures, and the like.

The region associated with the user model in the user model data 167 may be in units of regions C1, C2, and C3. Further, the user model can be associated with the specific areas A1, A2, and A3 including the points H1, H2, and the route P1. The specific areas A1 and A2 are ranges within a radius of 1 km centered on the points H1 and H2, respectively. The specific area A3 is within 200 m from the route P. These distances are, of course, just an example.

Since the specific areas A1, A2, and A3 are areas in which the user U is likely to know the directions in detail, it is assumed that the user U is familiar with the directions. On the other hand, the area C3 away from the points H1 and H2 and the route P is considered to be an area where the user U is unguided. By associating the user model with the user model data 167 in response to such a difference in each region, navigation suitable for the proficiency level and aptitude of the user U can be performed.

The user model data 167 may be generated by a device different from the navigation device 120 and stored in the user model data storage unit 144, but may be generated by the navigation device 120. In this case, the navigation device 120 can acquire the position information of the points H1 and H2 based on the position information registered as the home position or the work position by the operation of the user U. The navigation device 120 can acquire information on the route P by a process of searching for a route on which the vehicle 1 frequently travels and a process of recording the movement history of the vehicle 1. Further, the route registered by the user U by operating the navigation device 120 may be set as the route P. Further, the range and boundary position of the areas C1, C2, and C3 can be specified from the data stored in the map DB 141.

[1-3. Operation of navigation device]
7, 8 and 9 are flowcharts showing the operation of the navigation device 120, and FIG. 9 shows in detail the process of step S133 of FIG.

The operations of FIGS. 7, 8 and 9 are executed by the processing unit 130 of the navigation device 120. Specifically, the processing of step S101 is executed by the user identification unit 134, and the processing of S105, S106, S107, and S130 is notified. The control unit 137 executes the operation. The process of steps S102-S104, S121-S127, and S131 is executed by the guidance information generation unit 135. The processing of step S128 is executed by the notification unit 136 and the notification control unit 137, and the processing of steps S108, S129, and S132 is executed by the voice recognition unit 132 and the notification control unit 137. The processing of step S134 is executed by the processing unit 130.

Further, the processing of steps S151-S155, S157-S159, and S161 is executed by the notification unit 136 and the notification control unit 137, and the processing of steps S156 and S160 is executed by the guidance information generation unit 135. The processing of steps S162 and S163 is executed by the notification control unit 137, and the processing of step S164 is executed by the user model generation unit 138.

The processing unit 130 identifies the user U who uses the navigation device 120 (S101). In step S101, the processing unit 130 requests the user U to input the user name or user ID by the touch sensor 103 or voice, and identifies the user U, for example. In step S101, authentication may be performed by requesting input of authentication information such as a password together with a user name and a user ID.

Subsequently, the processing unit 130 accepts the input of the navigation condition (S102). The navigation condition is a condition for determining the route of the vehicle 1, and includes at least the location information of the destination, the location information of the waypoint, the departure point, etc., and whether or not to use the toll road. It may include whether or not to avoid a narrow road.

Based on the conditions input in step S102, the processing unit 130 executes the route search of the vehicle 1 (S103) and determines the route of the vehicle 1 (S104).
The processing unit 130 refers to the user model data 167 stored in the user model data storage unit 144, and determines whether or not there is the user model data 167 corresponding to the user U specified in step S101 (S105). When there is the corresponding user model data 167 (S105; YES), the processing unit 130 selects the user model data 167 (S106). If there is no corresponding user model data 167 or the user model is not set (S105; NO), the processing unit 130 makes a setting to use the default user model (S107). Even if the user ID cannot be specified in step S101, the process of step S107 is executed.

After setting step S106 or step S107, the processing unit 130 starts voice detection and voice recognition by the voice recognition unit 132 (S108). As a result, when the user U utters an instruction by voice, the navigation device 120 is in a state where the instruction by this utterance can be detected.

The processing unit 130 starts navigating the vehicle 1 according to the route determined in step S104 (S121). The processing unit 130 identifies the current position of the vehicle 1 by using GPS 119 and acquires the position information (S122).

The processing unit 130 selects a user model to be used for creating the guidance scenario (S123). In step S123, among the user models set in the user model data 167 selected in step S106, the user model corresponding to the position specified in step S122 is selected. If the default user model is set in step S108, the default user model is adopted in step S123.

The processing unit 130 searches for a guide point on the route determined in step S104 (S124), and determines whether or not there is a guide point close to the current position of the vehicle 1 (S125). Specifically, in step S125, it is determined whether or not there is a guide point that is not the processing target of step S127 within a predetermined range from the current position of the vehicle 1 in the traveling direction of the vehicle 1.

If it is determined that there is no corresponding guide point (S125; NO), the processing unit 130 returns to step S122. When it is determined that there is a corresponding guidance point (S125; YES), the processing unit 130 determines the number of notifications, the notification timing, and the content of the guidance information corresponding to the user model selected in step S123 (S126). In step S126, the processing unit 130 refers to, for example, the user model setting data 161. The processing unit 130 generates a guidance scenario according to the content determined in step S126 (S127).

The processing unit 130 executes the notification according to the guidance scenario generated in step S127 (S128). In step S128, one notification is executed out of the notification timings specified in the guidance scenario. In step S128, the processing unit 130 waits until the position of the vehicle 1 reaches the position corresponding to the notification timing.

After executing the notification, the processing unit 130 determines whether or not the utterance of the user U has been recognized (S129). In step S129, after the voice of the guidance information is output from the speaker 115, it is determined whether or not the voice instruction to the navigation device 120 is recognized from the voice collected by the microphone 113. Note that the voice collected by the microphone 113 while the guidance information is being output may be targeted.

When it is determined that the instruction voice is not recognized (S129; NO), the processing unit 130 determines whether or not the notification of the guidance scenario generated in step S127 is completed (S130). For example, when a plurality of notification timings are specified in the guidance scenario and there is a notification timing in which the notification is not executed, the processing unit 130 determines that the notification has not been completed. If the notification is not completed (S130; NO), the processing unit 130 returns to step S128.

When it is determined that the notification is completed (S130; YES), the processing unit 130 determines whether or not to end the navigation (S131). The processing unit 130 ends the navigation when the end of the navigation is instructed by the operation of the user U, when the vehicle 1 arrives at the destination, when the power supply of the navigation device 120 is shut down, and the like (S131; YES). ). If the navigation is not finished (S131; NO), the processing unit 130 returns to step S122.

When the utterance of the user U is recognized (S129; YES), the processing unit 130 determines whether or not the recognized utterance is a utterance subject to the notification adjustment process (S132). The symmetrical utterances of the notification adjustment process are the number of notifications, the timing, the content of the guidance information, or other instructions regarding the notification.

When it is determined that the utterance of the user U is not the utterance subject to the notification adjustment process (S132; NO), the processing unit 130 executes the process corresponding to the uttered instruction (S134), and proceeds to step S130. .. In step S134, for example, the processing unit 130 adjusts the output volume of the speaker 115.

When it is determined that the utterance of the user U is the utterance subject to the notification adjustment process (S132; YES), the processing unit 130 executes the notification adjustment process (S133), and then proceeds to step S130 after the execution.

FIG. 9 is a flowchart showing the notification adjustment process in detail.
The processing unit 130 determines whether or not the utterance of the user U is an utterance having a content negative to the notification (S151). The utterances with negative contents to the notification include, for example, utterances such as "I'm okay" and "Stop guidance" indicating that the notification is rejected or the notification is unnecessary. Further, when the timing at which the utterance is recognized overlaps with the voice of the guidance information, it may be determined as the utterance having a content negative to the notification. When it is determined that the utterance has a negative content to the notification (S151; YES), the processing unit 130 changes the guidance scenario generated in step S127 (S152). In step S152, the processing unit 130 changes the guidance scenario so that the number of notifications and / or the notification timing is reduced. After step S152, the processing unit 130 shifts to step S162 described later.

When it is determined that the utterance does not have a negative content with respect to the notification (S151; NO), the processing unit 130 determines whether or not the utterance is a request for re-notification of the guidance information (S153). When it is determined that the utterance requests the re-notification of the guidance information (S153; YES), the processing unit 130 refers to the guidance scenario, re-notifies the guidance information notified in step S128 (S154), and proceeds to step S162. Transition.

When it is determined that the utterance does not require re-notification of the guidance information (S153; NO), the processing unit 130 determines whether or not the utterance is related to the content of the guidance information notified in step S127 (S155). Specifically, in step S127, when the voice of the content of turning the vehicle 1 to the right at the intersection is output, the user U may say "Tell me the landmark of the intersection". When it is determined that the utterance is related to the content of the guidance information (S155; YES), the processing unit 130 changes the guidance scenario generated in step S127 (S156). In step S156, the processing unit 130 changes the guidance scenario so as to increase the content of the guidance information. The processing unit 130 executes the notification according to the changed guidance scenario (S157), and proceeds to step S162.

When it is determined that the utterance is not related to the content of the guidance information (S155; NO), the processing unit 130 determines whether or not the utterance requests information related to the guidance information notified in step S127 (S158). Specifically, in step S127, when a voice for guiding an interchange on an expressway is output, a user U asks whether there is a gas station in front of the interchange. When it is determined that the request is for information related to the guidance information (S158; YES), the processing unit 130 searches for the requested information in the map DB 141 and the route DB 142 (S159). The processing unit 130 changes the guidance scenario so that the guidance scenario generated in step S127 includes the information searched in step S159 (S160). The processing unit 130 executes the notification according to the changed guidance scenario (S161), and proceeds to step S162.

Further, when it is determined that the utterance does not require information related to the guidance information (S158; NO), the processing unit 130 ends the operation of FIG. 9 and proceeds to step S130.

In step S162, the processing unit 130 generates history information (S162). The history information is information on the history of executing the notification adjustment process of FIG. 9, and includes at least information on the utterance that caused the start of the notification adjustment process, that is, the content of the utterance recognized after the notification in step S128. .. For example, whether the recognized utterance is a utterance with negative content to the notification, a utterance requesting re-notification of the guidance information, a utterance regarding the content of the guidance information, or a utterance requesting information related to the guidance information. Contains information to indicate. The history information may include a part or all of the guidance scenario generated in step S127 or the modified guidance scenario. For example, the location information of the guide point may be included.

The processing unit 130 stores the history information generated in step S162 in the history storage unit 145 in association with the user U (S163). Further, the processing unit 130 generates or updates the user model data 167 based on the history information stored in the history storage unit 145 (S164), and proceeds to step S130.

In step S164, the processing unit 130 changes the user model set in the user model data 167 according to the utterance content of the user U. For example, when the user U utters a content that is negative to the notification, the user model is changed to a user model with low navigation utilization in order to reduce the number of notifications and the content of the guidance information. Further, for example, when the user U makes an utterance requesting re-notification of the guidance information, a utterance regarding the content of the guidance information, a utterance requesting information related to the guidance information, etc., the user model is changed to a user model with high navigation usage. ..
