(4) The information acquired in (3) is accumulated in an arbitrary storage area as accumulated information. Here, if the accumulated information has already been accumulated, it is added to the accumulated information.
(5) It is determined whether or not the accumulated information accumulated in (4) meets the accumulation condition.
(6) If it is determined that the condition is satisfied in (5), the route information acquisition process is terminated. If it is determined that the condition is not satisfied in (4), the end point position information included in the road information acquired in (2) is acquired.
(7) The end point position information acquired in (6) is set as the start point position information in (2), and the process returns to (2).

  For example, in (2) above, it may be determined whether the road information has been acquired once, and the road information acquired once may not be acquired. Also, for example, in (2) above, it is determined whether or not the calorie consumption information, time information, and distance information included in the road information to be acquired matches the cumulative condition, and the matching road information is acquired. May be. In (2) above, one or more pieces of road information whose position information acquired in (1) is end point position information may be acquired. In this case, in the above (6), the starting point position information included in the road information acquired in (2) is acquired. That is, the route information acquisition unit 135 sequentially acquires road information using the position information of the starting point position information or the main point position information included in the road information.

  In addition, the route information acquisition unit 135 normally acquires one or more route information according to the following cases.

  (A) When the position information acquisition unit 131 acquires position information

  In this case, for example, when the position information acquisition unit 131 acquires one piece of position information, the route information acquisition unit 135 uses the position information indicated by the position information or the position indicated by the position information. Get the route information as the start and end points. When acquiring the route information having the position indicated by the position information as the starting point or the ending point, for example, as described above, the route information acquiring unit 135 receives one or more items from the map information storage unit 11 until the cumulative information satisfies the cumulative condition.

Further, when acquiring the route information having the position indicated by the position information as the starting point and the ending point, the route information acquiring unit 135, for example, from the map information storage unit 11 until the cumulative information satisfies the cumulative condition as described above. The above road information is acquired. Then, from the acquired one or more pieces of route information, the starting point position information included in the first acquired road information and the end point information included in the last acquired road information acquire one or more pieces of route information as the position information. .

  Further, for example, when the position information acquisition unit 131 acquires two pieces of position information, that is, the first position information and the second position information, the route information acquisition unit 135 starts from the position indicated by the first position information. Route information whose end point is the position indicated by the two-position information is acquired. When acquiring the route information starting from the position indicated by the first position information and ending at the position indicated by the second position information, the route information acquisition unit 135, for example, as described above, the accumulated information satisfies the accumulation condition. Until then, one or more road information is acquired from the map information storage unit 11. Then, from the acquired one or more route information, the starting position information included in the road information acquired first is the first position information, and the end point information included in the road information acquired last is the second position information.

Further, the route attribute information includes one or more road attribute information.

  For example, the route information acquisition unit 135 first acquires one or more route information that matches the accumulation condition as described above. Then, one or more route information satisfying the jogging route condition is obtained from the obtained one or more route information. The determination as to whether or not the jogging route condition is satisfied is usually made by determining whether or not all of the one or more pieces of road attribute information that are route attribute information satisfy the jogging route condition.

  For example, it is assumed that the route information acquisition unit 135 acquires route information in which all roads included in the route have sidewalks as route information that matches the accumulation condition. In this case, it is assumed that the jogging route condition is “sidewalk = yes”. Then, the route information acquisition unit 135 acquires the route information as route information that satisfies the jogging route condition. In addition, the route information acquisition unit 135 has acquired route information that has a sidewalk as a route information that matches the accumulation condition (a road other than the part has no sidewalk). To do. In this case, it is assumed that the jogging route condition is “sidewalk = yes”. Then, the route information acquisition unit 135 acquires the route information as route information that approximately satisfies the jogging route condition.

  (C) When the walk route condition is stored in the walk route condition storage means 133

  In this case, the route information acquisition unit 135 normally acquires one or more route information having route attribute information that satisfies the walking route condition. Since the method and procedure for acquiring the route information in this case are the same as in (B) described above, description thereof will be omitted.

  (D) When cycling path conditions are stored in the cycling path condition storage means 134

Moreover, the map information acquisition part 14 acquires the map information which shows the map containing all the roads normally shown by the 1 or more road information which the said each route information has. The map information acquisition part 14 should just be able to acquire the said map information, and the method, a procedure, etc. are not ask | required.

  The traffic information storage unit 15 can store traffic information that is information related to traffic. The traffic information is, for example, current position information that is position information indicating the current position, or current road information that is road information indicating a road existing at the current position indicated by the current position information. The current road information is road information indicating a road that is currently passing. The traffic information includes calorie consumption information indicating calories consumed by passing a road or a route, icons indicating the calories consumed, routed route information indicating route traveled, and current travel speed. The moving speed information shown may be used. The moving speed information is information indicating the moving speed during travel. Note that the moving speed information may be a speed per hour, a speed per minute, a speed per second, or a format. Further, the traffic information storage unit 15 may store date information indicating a date corresponding to the traffic information.

  The icon acquisition unit 165 acquires from the icon management information storage unit 163 the icon corresponding to the calorie consumption condition that matches the calorie consumption information calculated by the calorie consumption information calculation unit 164. For example, the icon acquisition unit 165 first acquires the calorie consumption information calculated by the calorie consumption information calculation unit 164. Then, the icon acquisition unit 165 determines which of the consumption calorie conditions stored in the icon management information storage unit 163 the acquired calorie consumption information matches. Then, the icon acquisition unit 165 acquires an icon corresponding to the calorie consumption condition determined to match from the icon management information storage unit 163.

  The traffic information accumulation unit 17 accumulates the traffic information acquired by the traffic information acquisition unit 16 in the traffic information storage unit 15. Normally, the traffic information is current position information or current road information, but may be calorie consumption information, an icon indicating the calorie consumption, traveled route information, travel speed information, or the like. Further, the traffic information storage unit 17 may acquire date information indicating a date when the traffic information acquisition unit 16 acquires the traffic information, and may store the traffic information together with the date information.

  The output unit 18 outputs one or more pieces of route information acquired by the route information acquisition unit 13. When the map information acquisition unit 14 acquires map information, the output unit 18 outputs the route information acquired by the route information acquisition unit 13 and the map information. In this case, the output unit 18 normally outputs the route indicated by the route information on the map indicated by the map information. In this case, the output unit 18 usually outputs the road information included in the map information and the road information included in the route information in association with each other. “Output in association” is to output so that the correspondence between the road information included in the map information and the road information included in the route information can be understood.

  The output unit 18 outputs the icon acquired by the icon acquisition unit 165. The output unit 18 may output the traffic information acquired by the traffic information acquisition unit 16. For example, when outputting an icon, the reception unit 12 normally receives an icon output instruction that is an instruction to output an icon, and the output unit 18 outputs the icon acquired by the icon acquisition unit 165 according to the instruction. For example, when outputting the traffic information, the reception unit 12 receives a traffic information output instruction that is an instruction to output the traffic information, and in accordance with the instruction, the output unit 18 outputs the traffic information acquired by the traffic information acquisition unit 16. Output.

  Also, output refers to display on a display, projection using a projector, printing with a printer, sound output, transmission to an external device, accumulation in a recording medium, processing to other processing devices or other programs, etc. It is a concept that includes delivery of results. In addition, regarding transmission, accumulation, and delivery of processing results, an output target is finally presented to the user.

(Specific example 1)
Next, a specific example of the operation of the navigation device 1 will be described. In this specific example, the navigation device 1 is assumed to be a form terminal having a navigation function. In this specific example, “route” is referred to as “course”.

  (Example 1: Acquisition of route information)

  In this example, it is assumed that the map information storage unit 11 stores the map information shown in FIG. In addition, as shown in FIG. 6, the map information of FIG. 5 is provided with a point identifier (alphabet) for identifying a point that is an intersection of roads on the map. Further, the road information indicating the road is, for example, as illustrated in FIG. 7, and the road information is stored in the map information storage unit 11. In addition, the road information includes an ID for uniquely identifying each record, a road identifier (item name: identifier), a point identifier of the starting point (item name: starting point), and a point identifier of the end point ( Item name: end point), width information (item name: width), distance information (item name: distance), calorie consumption information (item name: calorie consumption), and time information (time). Note that “[m]” in each item name is a unit.

  First, it is assumed that the user performs an operation on the terminal device for proposing a course having a course distance of about 3 km and suitable for jogging and having a current position as a start point and an end point. Then, the reception unit 12 receives the accumulation condition “distance = 3 km” and the route type condition “jogging”.

  Next, it is assumed that the position information acquisition unit 131 acquires position information, is current position information indicating the current position of the user, and acquires position information indicating the position of the point L in FIG.

  Next, it is assumed that the route information acquisition unit 135 acquires the jogging route condition from the jogging route condition storage unit 132 and acquires the jogging route condition “width ≧ 6 m”.

  Next, the route information acquisition unit 135 acquires road information having the position of the point L in FIG. 6 as a start position or an end position from the road information in FIG. In the road information shown in FIG. 7, the road information whose start position or end position is the point L is “ID = 025”, “ID = 026”, “ID = 027”, “ID = 030”, “ID = 031”. Is. Among the road information, road information satisfying the jogging route condition “width ≧ 6 m” is “ID = 025”, “ID = 027”, “ID = 030”, and “ID = 031”. Therefore, the route information acquisition unit 135 acquires the road information of “ID = 025”, “ID = 027”, “ID = 030”, and “ID = 031” in FIG. Note that these road information is the first road information.

  Next, the route information acquisition unit 135 arbitrarily stores the accumulated information included in the acquired road information of “ID = 025”, “ID = 027”, “ID = 030”, and “ID = 031” in FIG. Accumulate in the area. At this time, the route information acquisition unit 135 accumulates each accumulated information in different storage areas in order to identify each accumulated information. Moreover, since the accumulation condition received by the receiving unit 12 is a distance condition, the route information acquisition unit 135 may store only the distance information included in the acquired road information in an arbitrary storage area.

  Next, the route information acquisition unit 135 determines whether each accumulated information satisfies the accumulation condition “distance = 3 km”. Among the accumulated information, the accumulation satisfying the accumulation condition is performed. There is no information. Therefore, the route information acquisition means 135 acquires the road information having the start position or end position of the road indicated by the first road information as the start position or end position from the road information of FIG. For example, for the road information of “ID = 025” in FIG. 7, the road information of “ID = 021” and “ID = 023” having the point I as the end point position is acquired. Further, for example, for the road information of “ID = 027” in FIG. 7, the roads of “ID = 024”, “ID = 028”, “ID = 029” having the point K as the starting point position or the ending point position. Get information. At this time, the reference first road information is not acquired because it overlaps. The road information acquired by using the starting position or the end position of the road indicated by the first road information as the starting position or the end position is set as the second road information.

  Next, the route information acquisition unit 135 accumulates accumulated information included in the second road information in an arbitrary storage area. At this time, the route information acquisition unit 135 accumulates accumulated information included in each second road information so as to be added to accumulated information included in the first road information serving as a reference.

  Next, the route information acquisition unit 135 determines whether each accumulated information satisfies the accumulation condition “distance = 3 km”. Among the accumulated information, the accumulation satisfying the accumulation condition is performed. There is no information. Therefore, the route information acquisition unit 135 acquires road information having the start position or end position of the road indicated by the second road information as the start position or end position from the road information of FIG.

  As described above, the route information acquisition unit 135 obtains the route information while sequentially acquiring the first road information, the second road information, the third road information,... get. Further, at the time of acquisition, it is determined whether or not the jogging path condition is satisfied. After acquisition, it is determined whether or not the accumulated information satisfies the accumulated information. As a result, the route information acquisition means 135 changes each point of FIG. 6 to “L → M → J → G → D → C → B → A → H → K → L”, “L → M → J → G → F”. → E → B → A → H → K → L ”,“ L → M → J → G → D → C → B → A → H → I → L ”,“ L → M → J → G → F → E ” It is assumed that four route information indicating four courses passing in the order of “→ B → A → H → I → L” is acquired.

  Next, the map information acquisition unit 14 acquires, from the map information storage unit 11, map information indicating a map including the course indicated by the four route information acquired by the route information acquisition unit 13. Then, the output unit 18 outputs the four route information and the map information. The state of the output at this time is, for example, as shown in FIG.

  (Example 2: Acquisition and accumulation of traffic information)

  First, it is assumed that the user starts jogging according to the course proposed in Example 1. Then, the current position information acquisition unit 161 acquires current position information at a predetermined timing. The current road information acquisition unit 162 acquires road information indicating a road existing at the position indicated by the current position information from the map information storage unit 11 each time the current position information acquisition unit 161 acquires the current position information. To do. At this time, the current road information acquisition unit 162 may not acquire the current road information when the current road information is the same as the previously acquired current road information. Then, the traffic information storage unit 17 stores the current position information and the current road information in the traffic information storage unit 15. Here, it is assumed that the traffic information accumulation unit 17 accumulates the current position information and the current road information together with the date.

  In this way, the current position information acquisition unit 161 and the current road information acquisition unit 162 continue to acquire the current position information and the current road information while the user is jogging, and the traffic information storage unit 17 Each time the information is acquired, the information is accumulated.

  Next, it is assumed that the user has finished jogging. Then, the calorie consumption information calculation means 164 acquires the traffic information corresponding to the date on which jogging was performed from the traffic information storage unit 15 and calculates the calorie consumption information corresponding to the date based on the traffic information. And the icon acquisition means 165 acquires the icon corresponding to the said calorie consumption information from the icon management information storage means 163. Then, the traffic information storage unit 17 stores the calorie consumption information and the icon in the traffic information storage unit 15. Here, it is assumed that the traffic information accumulation unit 17 accumulates the calorie consumption information and the icons together with the date.

  In this way, the calorie consumption information calculation unit 164 and the icon acquisition unit 165 calculate the calorie consumption information based on the traffic information stored in the traffic information storage unit 15 after the user finishes jogging. An icon corresponding to the calorie consumption information is acquired. In addition, the traffic information accumulation unit 17 accumulates these pieces of information every time these are calculated and acquired.

  (Example 3: Output of traffic information)

  First, it is assumed that after the user finishes jogging on the course proposed in Example 1, the user has performed an operation for displaying the calories consumed by walking, jogging, and the like in the form of icons. Then, the reception unit 12 receives an icon output instruction.

  Next, the output unit 18 acquires and outputs the icon stored in the traffic information storage unit 15 according to the icon output instruction. The state of the output at this time is, for example, as shown in FIG.

  In this specific example, an example of acquiring route information indicating a route suitable for jogging has been shown. However, route information indicating a route suitable for a walk or a route suitable for cycling may be acquired. In this case, the route information acquisition unit 135 normally acquires route information that matches the route condition from the acquired route information using the walk route condition and the cycling route condition.

  Moreover, in this specific example, although the example which acquires the path | route information which shows the path | route with the same starting point and an end point was shown, you may acquire the path | route information which shows the path | route where the starting point and an end point are not the same.

  Further, in this specific example, while obtaining road information and accumulating cumulative information, an example of determining whether the cumulative information satisfies a cumulative condition has been shown. For example, all the route information that can be acquired is You may acquire from the map information storage part 11, and may acquire one or more route information which satisfy | fills accumulation conditions among the acquired one or more route information.

Moreover, the weather information acquisition part 22 may acquire the weather conditions which the reception part 12 received as weather information. Moreover, the weather information acquisition part 22 may always acquire weather information after the navigation apparatus 2 is turned on.

  The weather information acquisition unit 22 can be usually realized by hardware (dedicated circuit) such as a so-called temperature sensor, humidity sensor, and wind direction sensor, but may be realized by an MPU, a memory, or the like. The processing procedure of the weather information acquisition unit 22 is usually realized by software, and the software is recorded in a recording medium such as a ROM.

  The route attribute condition acquisition unit 23 acquires, from the weather route attribute condition storage unit 21, a route attribute condition corresponding to a weather condition that matches the weather information acquired by the weather information acquisition unit 22. For example, the route attribute condition acquisition unit 23 first acquires the weather information acquired by the weather information acquisition unit 22. Then, the route attribute condition acquisition unit 23 determines which of the weather conditions stored in the weather route attribute condition storage unit 21 the acquired weather information matches. Then, the route attribute condition acquisition unit 23 acquires a route attribute condition corresponding to the weather condition determined to be matched from the weather route attribute condition storage unit 21.

  When the route attribute condition corresponding to the weather condition is change information, for example, the route attribute condition acquisition unit 23 changes the cumulative condition received by the reception unit 12 according to the change information, and sets the changed cumulative condition. The route attribute condition may be acquired.

  The route information acquisition unit 24 acquires one or more route information from the map information storage unit 11. The route information acquisition unit 24 usually acquires one or more route information whose route attribute information matches the route attribute condition acquired by the route attribute condition acquisition unit 23. “Match” includes broadly matching and is widely understood. Note that the route information acquisition method and procedure in the route information acquisition unit 24 differ only in the conditions for determining whether or not the route information is acquired and the target information is different. Since it is the same as the route information acquisition method and procedure in the unit 13, the description thereof will be omitted.

The route information acquisition unit 241 acquires route information in the following procedure, for example.
(1) Acquire position information indicating a position that is a starting point of a route.
(2) One or more road information whose position information acquired in (1) is starting point position information is acquired from the map information storage unit 11.
(3) The road attribute information included in the road information acquired in (2) is acquired.
(4) The information acquired in (3) is accumulated in an arbitrary storage area as route attribute information. Here, if the route attribute information has already been accumulated, it is added to the accumulated route attribute information.
(5) It is determined whether or not the route attribute information accumulated in (4) matches the route attribute condition.
(6) If it is determined that the condition is satisfied in (5), the route information acquisition process is terminated. If it is determined that the condition is not satisfied in (4), the end point position information included in the road information acquired in (2) is acquired.
(7) The end point position information acquired in (6) is set as the start point position information in (2), and the process returns to (2).

  For example, in (2) above, it may be determined whether the road information has been acquired once, and the road information acquired once may not be acquired. Further, for example, in (2) above, it may be determined whether or not the road attribute information included in the road information to be acquired matches the route attribute condition, and the matching road information may be acquired. In (2), one or more road information whose position information acquired in (1) is end point position information may be acquired. In this case, in (6), the starting point position information included in the road information acquired in (2) is acquired. That is, the route information acquisition unit 135 sequentially acquires road information using the position information of the starting point position information or the main point position information included in the road information.

Further, the route information acquisition unit 241 normally acquires one or more route information according to the following cases (A) to (D). Is the route attribute information and the cumulative condition is the route attribute condition, and the other processing methods and procedures are the same.
(A) When the position information acquisition unit 131 acquires position information (B) When the jogging route condition is stored in the jogging route condition storage unit 132 (C) The walking route condition is stored in the walk route condition storage unit 133 (D) When cycling path conditions are stored in the cycling path condition storage means 134

  Note that the route attribute condition acquisition unit 23 and the route information acquisition unit 241 can be usually realized by an MPU, a memory, or the like. The processing procedure of the route information acquisition unit 241 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  FIG. 12 is a flowchart showing the path information acquisition process in step S1103 of the flowchart of FIG. In FIG. 12, steps S1201 to S1204 and steps S1208 to S1211 are the same as steps S301 to S304 and steps S308 to S311 in FIG.

  (Step S1205) The route information acquisition unit 241 acquires road attribute information from the road information acquired in Step S1204.

  (Step S1206) The route information acquisition unit 241 accumulates the road attribute information acquired in Step S1205 as route attribute information in an arbitrary storage area.

  (Step S1207) The route information acquisition unit 241 determines whether the route attribute information accumulated in an arbitrary storage area matches the route attribute condition acquired in Step S1102. If they match, the process proceeds to step S1209; otherwise, the process proceeds to step S1208.

  Note that the processing of step S1210 and step S1211 in the flowchart of FIG. 12, that is, when jogging route conditions are stored in the jogging route condition storage means 132, one or more pieces of route information acquired in steps S1202 to S1208. To obtain route information that matches the jogging route condition. If the walk route condition is stored in the walk route condition storage unit 133, route information that matches the walk route condition is acquired from one or more pieces of route information acquired in steps S1202 to S1208. When the cycling route condition is stored in the cycling route condition storage unit 134, route information that matches the cycling condition is acquired from one or more route information acquired in steps S1202 to S1208.
