Although not shown, the navigation device 100 includes a CPU (Central Processing Unit), a program storage unit, an OS (Operating System), and the like.

  The control unit 10 is configured by, for example, a CPU, and each component of the navigation device 100 is configured according to a computer program (a computer program for causing the navigation device 100 to perform operation control and includes a navigation program) stored in the storage unit 20. Central control of the elements, route search function, route guidance function, service information (store information such as gas stations, convenience stores, ramen stores, hotels and inns, POI (Point Of Interest) information such as famous facility information, resort information) And various functions for executing various processes including an information search function for searching. In addition, these various functions are implement | achieved by the well-known technique with which a general navigation apparatus is provided. The configuration of the control unit 10 will be described in detail later (see FIG. 2).

  The storage unit 20 includes a ROM, a RAM, and the like, and is a storage medium that stores various computer programs used by the navigation device 100 and various information necessary for the navigation device such as map information. The configuration of the storage unit 20 will be described in detail later (see FIG. 2).

  The memory 30 is a storage medium that temporarily holds various types of information processed by the control unit 10 and is configured by a semiconductor storage device such as a RAM.

  The output unit 40 has a function of outputting various types of information, particularly information related to route guidance, in a form that can be recognized by the user. For example, the output unit 40 outputs an image display device (display device, monitor) that displays image information and audio information. Audio output device (speaker device). The image display device displays road map information and user's current position information on the display screen, and also displays a recommended movement route to the destination on the display screen, thereby visually informing the route and the like. .

  The voice output device outputs various voices based on the various voice information, so that the route of the moving route (for example, “turn right at 100 m”) or information related to the moving route (for example, road) Name, traffic regulation information, introduction of nearby recommended facilities, etc.). Note that the output unit 40 including the voice output device receives a notification from the control unit 10 and performs voice guidance and the like.

  The sensor unit 50 has a function of measuring the current position of the navigation device 100 (that is, the current position of the user). For example, the sensor unit 50 receives a GPS signal transmitted from a GPS satellite, and positions based on the GPS signal. A GPS sensor that measures the amount of movement, a speed sensor that measures the amount of movement (distance) from the initial position, a gyro sensor that measures the traveling (movement) direction, and the like.

  A GPS sensor is a so-called GPS receiver, receives a GPS signal radiated from a GPS satellite, measures a distance (pseudo distance) between the GPS satellite and the GPS receiver itself, and receives a plurality of satellites. Are simultaneously received to calculate the current position (GPS positioning solution) of the GPS receiver itself.

  In addition to the GPS receiver (antenna) that receives the GPS signal, the sensor unit 50 has a function of performing processing such as decoding of the received GPS signal and notifying the control unit 10.

  The communication unit 60 is connected to a communication network such as the Internet wirelessly or by wire, and has a function for transmitting / receiving information to / from an external device such as a management server connected to the communication network.

  The input unit 70 has a function of accepting various instructions to the control unit 10 from the user. In this example, the input unit 70 includes, for example, operation buttons displayed on the display screen of the display unit 40.

  FIG. 2 is an explanatory diagram for explaining an example of the configuration of the control unit 10 and the storage unit 20 in this example. As shown in FIG. 2, the control unit 10 includes a sensor information processing unit 11, a communication processing unit 12, a search condition determination unit 13, a search range determination unit 14, a search unit 15, and a route search unit 16. Including.

  The sensor information processing unit 11 has a function of executing processing for acquiring or storing sensor information such as position information and speed information by the sensor unit 50. That is, the navigation device 100 specifies the current position of the user by the sensor information processing unit 11.

  The communication processing unit 12 has a function of executing processing for transmitting and receiving various types of information by the communication unit 60. In this example, the communication processing unit 12 performs processing for acquiring various information such as weather information and road condition information described later from an external server or the like via a communication line such as the Internet.

  The search condition determination unit 13 has a function of executing processing for determining a search condition for a break point when the user moves to a destination based on user information described later. In this example, the search condition determination unit 13 determines a search condition based on a user's behavior history and preference information included in user information described later. Further, the search condition determination unit 13 in this example reflects the weather information in the search conditions. Specifically, the search condition determination unit 13 searches for an outdoor break point on a sunny day based on weather information indicating preset items such as weather, date / time, and temperature when searching for a recommended travel route. "To be excluded from" or "to search for an underground break point on a typhoon day" is determined as a search condition.

  In addition, the search condition determination unit 13 reflects the road condition, particularly the road condition affected by the weather, in the search condition. Here, the “road condition information” may be information related to the road condition. That is, as examples of road condition information, for example, various information such as “a road that is highly likely to be damaged due to rain” and “a road that can avoid direct sunlight on a sunny day” can be considered. In addition, reflecting road condition information in search targets includes, for example, “excluding break points located around roads that are wet with rain from search targets” or “in roads where direct sunlight can be avoided on sunny days. This means that the search condition is “to set a resting point as a search target”.

  The search range determination unit 14 has a function of executing a process of determining a search range for rest point information based on an arbitrary point. In this example, the search range determination unit 14 determines a search range for a break point based on the current position of the user and the destination. Specifically, the search range determination unit 14 sets a range of a predetermined shape with reference to any two points (for example, an elliptical range having a focus on the current position and the destination) as the search range. The method for determining the search range is not particularly limited. For example, when the map is classified into a plurality of areas, the area to which any two points (current position and destination) belong on the map is set as the search range. It is good also as composition to do.

  The search unit 15 has a function of executing processing for searching for break point information satisfying the search condition determined by the search condition determination unit 13 from break point information stored in a break point information storage unit 22 described later. .

  The route search unit 16 performs route search processing for deriving a travel route from a departure position (for example, the current position of the user or a position input by the user) to a destination (for example, a position selected by the user on the map). It has the function to do. In the route search process, for example, input of information indicating a departure place (for example, current position) and a destination is received via the input unit 70, and based on the received information, road information is referred to from the departure place. A process of deriving a travel route to the destination and generating a map around the travel route including a road map including the derived travel route is performed. In addition, since a well-known technique is used about a route search process, detailed description here is abbreviate | omitted. In addition, information necessary for route search processing, for example, map information used for specifying the current position and generating a map around the moving route may be stored in the storage unit 20 in advance, or the communication unit 60 may be used. It is good also as a structure acquired from an external management server.

  In addition, the route search unit 16 in this example has a function of executing a process of searching for a recommended travel route that uses the break point indicated by the break point information searched by the search unit 15 as a transit point.

  As shown in FIG. 2, the storage unit 20 includes a road map information storage unit 21, a break point information storage unit 22, and a user information storage unit 23.

  The road map information storage unit 21 is a storage medium that stores map information divided into a predetermined grid (in this example, a rectangular range divided by a constant latitude width and latitude width). In addition to being stored in the road map information storage unit 21, this map information can be stored in an auxiliary storage device as a removable medium called an SD memory card, a CD-ROM, a DVD-ROM, or the like. Further, the map information may be downloaded via a communication network such as the Internet. In addition, the road map information storage unit 21 manages roads by representing nodes and links as road information indicating traffic regulation, road configuration, and the like. It is a storage medium for storing. That is, the route search unit 11 acquires information necessary for the route search process from the road map information storage unit 21. Hereinafter, information in which map information and road information are appropriately associated is referred to as “road map information”.

  The road information may be different depending on the time and the traveling direction of the vehicle. Here, in the road information in this example, the length and passage time of each link are stored as route costs. In addition, the road information has a plurality of hierarchies. In this example, the road information is for neighborhood (stores all roads), for short distance (stores roads other than narrow streets), for medium distance (prefecture roads or more). Storage) and long-distance use (stores highways and national roads). In this case, for example, hierarchical information may be set for the nodes and links constituting the road information. Thereby, the road information which is the object of the route search can be properly used depending on the route search condition. That is, for example, when the distance from the current position to the destination is a long distance, the amount of road information existing between them is enormous, so the route search process is performed using the road information set for long distance. By doing so, the processing load of the route search unit 11 can be reduced.

  The road information in this example includes passage information that is information about stairs and slopes. By including passage information indicating the position and size of stairs and slopes, for example, according to user information to be described later, a travel route with many stairs and slopes can be provided as a recommended travel route.

  The break point information storage unit 22 is a storage medium for storing break point information, which is information related to a break point indicating a point where the user can take a break. The “rest point” here is not limited to a store or a park, but may be a point where a bench, a vending machine, or the like is installed, for example.

  FIG. 3 is an explanatory diagram illustrating an example of a storage state of break spot information in the break spot information storage unit 22. As shown in FIG. 3, the rest point information in this example includes a rest point ID for uniquely identifying a rest point, a name of the rest point, and a rest point (or a facility located at the rest point. Rest facility. ) Availability conditions and usage flags.

  Here, the “usable condition” indicates a condition that the user should satisfy in order to use the resting point. In this example, for example, availability of the store according to the business date and time of the store or the weather ( For example, if it is an outdoor bench, it cannot be used when it rains).

  Further, the “use flag” indicates whether or not it is a resting point that satisfies a search condition determined based on user information described later and other information (in this example, weather information and road condition information). Is. In this example, among the rest points located within the search range determined by the search range determination unit 15, “1” is set for a break point that satisfies the search condition, and “0” is set for a break point that does not satisfy the break condition. Are set respectively. Note that a break point that is not within the search range is not set as a search condition, and therefore, even when the search condition is satisfied, “0” is set in the use flag. Therefore, in this example, being within the search range is one of the search conditions. The break point information may be information regarding the break point, and may include, for example, information indicating the surrounding environment of the break point (or the location condition of the break facility).

  The user information storage unit 23 is a storage medium for storing user information indicating predetermined information about the user. In this example, the user information will be described using an example in which information including the user's health status is stored.

  FIG. 4 is an explanatory diagram illustrating an example of a storage state of user information in the user information storage unit 23. As shown in FIG. 4, the user information in this example includes a user ID for uniquely identifying a user, a user's physical information, a movement method, a recommended continuous movement amount, an action history, and a user's preference. Display preference information.

  Here, the “body information” is information necessary for estimating the user's health status, and the recommended continuous movement amount is determined based on the body information. In this example, it is assumed that the body information includes various information such as normal fever, average blood pressure, age, presence / absence of sickness, etc. in addition to the user's height and weight.

  The “movement method” indicates a movement method of the user, and in this example, a recommended continuous movement amount is set for each of walking, running, and bicycle.

  The “recommended continuous movement amount” indicates “a movement amount that is considered to be satisfactory even if the user moves without taking a break” estimated from the physical information of the user. Therefore, it can be said that the recommended continuous movement amount is information indicating a recommended break interval. In this example, the recommended continuous movement amount is indicated by time and distance for each weather. The recommended continuous movement amount may be set not only by the weather but also by humidity and temperature.

  In addition, the “behavior history” only needs to indicate a history of user behavior. For example, the distance traveled by the user within a predetermined period, the type of facility visited, the interval at which the user took a break during travel, and the like. included.

  The “preference information” indicates the user's preference regarding movement. For example, “priority is given to the underpass on a sunny day” or “on a cloudy day compared to a sunny day, "Let the interval be long" is set. Note that the preference information may be configured to be set by the user or may be set based on the action history. When the preference information is set based on the action history, for example, the reference unit (reference information) for setting the preference information from the action history may be stored in the storage unit 20.

  The recommended continuous movement amount in the user information may be set based on not only the body information but also the action history and preference information. That is, the recommended continuous movement amount may be configured such that a basic value is calculated using a predetermined arithmetic expression based on physical information, and the behavior history and preference information are reflected in the value. . More specifically, for example, when it can be estimated that the user prefers to move more than the recommended continuous movement amount based on the action history, the recommended continuous movement amount is increased (longer time or distance). If the user can assume that the user takes a longer interval until the break on a cloudy day than on a sunny day, the recommended continuous movement amount corresponding to the cloudy day is increased. May be. In this case, it is preferable that the control unit 10 is configured to update the user information at a predetermined time.

  Next, the concept of navigation processing executed by the navigation device 100 will be described with reference to the drawings.

  FIG. 5 is an explanatory diagram for explaining the concept of navigation processing executed by the navigation device 100. As shown in FIG. 5A, it is assumed that there is a search range SR that is determined based on the user's current position P and destination G.

  In this case, the navigation device 100 first searches for the rest points BP1 to BP3 that satisfy the search condition within the search range SR, as shown in FIG.

  When searching for a break point, the navigation apparatus 100 searches for a recommended travel route R1 that appropriately passes through the break point based on the user information, as shown in FIG. Therefore, there may be a break point that is not selected as a transit point of the recommended travel route R1, such as the break point BP3. In addition, the recommended travel route R1 may not coincide with the shortest route R2 from the current position P to the destination G.

  In addition, when there are a plurality of routes that pass through the break points within a range that does not exceed the recommended continuous movement amount according to the user, the navigation device 100 may be configured to use a route with few break points as a recommended movement route, It is good also as a structure which makes the route in which a rest point agree | coincides with a user preference become a recommended movement path | route. Further, the navigation device 100 may be configured to exclude a route whose break point interval is shorter than a predetermined threshold from the recommended travel route candidates.

  Next, the operation of the navigation device 100 in this example will be described with reference to the drawings. Note that detailed descriptions of processes not particularly related to the present invention may be omitted.

  FIG. 6 is a flowchart illustrating an example of navigation processing executed by the navigation device 100. In the navigation process, a process for searching for a recommended travel route in consideration of the health aspect of the user A of the navigation device 100 and starting route guidance is performed.

  The navigation process in this example is started when, for example, the control unit 10 receives a search request for a recommended movement route including a destination designation by the user A via the input unit 70.

  In the navigation process, first, the control unit 10 acquires user information corresponding to the user A (step S101). In this example, the control unit 10 reads user information corresponding to the user A among the user information stored in the user information storage unit 23.

  When acquiring the user information, the control unit 10 specifies the current position of the user A by the sensor information processing unit 11 (step S102). At this time, an arbitrary departure point input from the user A may be accepted.

  When the current position is specified, the control unit 10 causes the search range determination unit 14 to determine a search range corresponding to the current position and the destination (step S103).

  When the search range is determined, the control unit 10 uses the communication processing unit 12 to acquire weather information corresponding to the search range (step S104). That is, the control unit 10 acquires the weather information of the area including the latitude and longitude according to the search range from an external server or the like. The control unit 10 may be configured to receive weather information from the user A.

  When the weather information is acquired, the control unit 10 acquires road condition information corresponding to the search range by the communication processing unit 12 (step S105).

  When the road condition information is acquired, the control unit 10 causes the search condition determination unit 13 to determine a search condition for a break point (that is, break point information) (step S106).

  When the search condition for the break point information is determined, the control unit 10 causes the search unit 15 to search for break point information that satisfies the determined search condition (step S107).

  When the rest point information satisfying the search condition is searched, the control unit 10 causes the route search unit 16 to determine the destination from the current position based on the rest point indicated by the searched break point information and the recommended continuous movement amount indicated by the user information. The recommended travel route is searched for (step S108).

  In this example, the route search unit 16 first searches for a route from the identified current position to a resting point or destination that can move within a range not exceeding the recommended continuous movement amount. Next, a route from a resting point that can be reached by the searched route to a resting point or destination that can move within a range not exceeding the recommended continuous movement amount is searched. Then, a search is made for a movement route in which the break interval does not exceed the recommended continuous movement amount among routes for moving from the current position to the destination via (or without) the break point.

  When the recommended travel route is searched, the control unit 10 starts route guidance based on the searched recommended travel route (step S109), and ends the processing here.

  At this time, the control unit 10 presents a plurality of recommended travel routes including the shortest route to the destination to the user A in a selectable manner, and provides route guidance based on the recommended travel route accepted by the user A. It may be configured to start.

  As described above, in the above-described embodiment, the current position of the user A is displayed on the map on the display screen of the display device (for example, the display screen of the image display device included in the display unit 40). The navigation device 100 that guides to the ground stores a road map information storage unit 21 that stores road map information, and a break point information storage unit 22 that stores break point information that is information about a break point indicating a point where the user A can take a break. And a user information storage unit 23 for storing user information indicating predetermined information related to the user A (for example, physical information, behavior history, preference information, and recommended continuous movement amount according to the movement method), the user information Based on this, a search condition for break point information when user A moves to the destination is determined, break point information satisfying the determined search condition is searched, and a road map Based on the information, it is configured to search for a recommended travel route that uses the break point indicated by the searched break point information as a waypoint, so a new method for setting a route in consideration of the health of the user is realized. Will be able to.

  In other words, by searching for a resting point located between the current position and the destination and searching for a recommended travel route that takes into account information about the resting point searched, a route including a resting point that is more suitable for the user (recommended It is possible to set a movement route.

  In addition, when moving by walking, it is possible to set a recommended moving route including a resting point as a stopover point, so heat consumption such as heat stroke due to consumption of physical strength and mood changes according to the surrounding situation at the time of movement Risk can be prevented. In addition, by taking the break point information into consideration, it is possible to search for a recommended travel route in consideration of the location conditions of the break point and the like.

  In the above-described embodiment, the break point information includes a recommended condition (for example, an available condition) corresponding to the weather or the like for each break point, and the navigation apparatus 100 identifies and identifies the current position of the user A. The search range for resting point information is determined based on the current location and destination, and the weather information corresponding to the determined search range is acquired, and the acquired weather information is reflected in the search conditions. It is possible to set a recommended travel route including a break point suitable for the situation.

  In the above-described embodiment, the navigation device 100 acquires the road condition information indicating the road condition according to the determined search range, and reflects the acquired road condition information in the search condition. It is possible to set a recommended travel route including a break point suitable for the actual situation.

  In the above-described embodiment, the user information includes a recommended continuous movement amount based on the physical information of the user A, and the navigation device 100 can move within a range that does not exceed the recommended continuous movement amount at least from the specified current position. Since it is set as the search condition that it is the rest point information which shows a rest point, it becomes possible to set the recommended movement path | route according to a user's condition more.

  In particular, in pedestrian navigation, since the moving body is a human, acquisition of a break from its health is an important factor. In particular, it is necessary to set a route on the premise that a break is acquired instead of giving priority to arriving at the destination early in the summer, when the risk of heat stroke is high. According to the above-described embodiment, for example, on a cloudy day as compared with a sunny day, a route can be set in consideration of such a condition that a long interval is taken until a break and a long walk is possible. Become.

  In the above-described embodiment, since the user information includes the behavior history of the user A, the health situation corresponding to the actual behavior of the user A is estimated (for example, the recommended continuous movement based on the behavior history) Since the rest point search condition can be determined (by setting or adjusting the amount), it is possible to set a recommended travel route where the rest point is located at an interval more suitable for the user.

  Although not particularly mentioned in the above-described embodiment, the navigation device 100 may be configured to set a break time at a break point based on user information. Moreover, when the predetermined ratio with respect to the rest time which the user stayed at the break point exceeds is set, the navigation device 100 may notify the user of that fact.

  In this case, the navigation device 100 may calculate the rest time at the rest point according to the movement amount (time or distance) that the user has moved to the rest point.

  Although not particularly mentioned in the above-described embodiment, the navigation device may be configured to guide a user to a resting point located around the current position during route guidance.

  INDUSTRIAL APPLICABILITY The present invention is industrially useful in the industry that handles devices that provide user guidance, and is particularly useful for improving the convenience of navigation devices that take into account the health of the user.
