Abstract

PROBLEM TO BE SOLVED: To contribute to operation for granting an incentive of selecting a detour route to a user of a vehicle.

SOLUTION: When information regarding a recommended detour point which is a point identified on the basis of an accident risk when a vehicle CR passes by, is received from an information processing device, a processing control unit 110D, in an information generation device 100D, presents, using presentation part which is, a display unit 220, etc., information regarding the recommended detour point to a user of the vehicle CR. Then, when the vehicle CR has passed by the recommended detour point, the processing control unit 110D generates non-detour information that indicates the recommended detour point has been passed by. The processing control unit 110D then transmits the generated non-detour information to the information processing device. When the non-detour information transmitted from the information generation device 100D is received, a storage control unit causes information in which the non-detour information is reflected to be stored in a storage unit in association with the identification information of the information generation device 100D.

2. Description of the Related Art Conventionally, devices have been used that search for a route from a starting point to a destination and present it to a user of a mobile object such as a vehicle. As a technology related to such a device, a technology has been proposed that predicts a sudden change in the situation and presents a safe route (see Patent Document 1: hereinafter referred to as "conventional example").

In such a conventional technique, in addition to vehicle information including the size or weight of the vehicle, vehicle position information, route information indicating the planned travel route, and terrain information of the planned travel route, weather information for the range including the planned travel route is provided. Based on this, the traffic obstruction phenomenon on the road included in the planned travel route is predicted. Subsequently, the predicted traffic obstruction phenomenon and the vehicle information are collated, and a process of identifying difficult-to-pass points on the planned travel route is performed. Then, when the difficult-to-pass point is identified, a route that bypasses (avoids) the identified difficult-to-pass point is searched, and the searched detour route is presented. .

The present invention also includes an information generation program characterized by causing a computer of the information generation device to execute the above-described information generation method.

It is also assumed that the guide route for the mobile object MV has already been set, and that the information generating device 700 is providing guidance when moving along the guide route.

<Process of generating information on recommended detour points>
First, the process of generating information about recommended detour points performed by the recommended detour point extraction unit 840 will be described. The recommended detour point extraction unit 840 executes a process of generating information on recommended detour points in response to receiving the current position information transmitted from the information generation device 700 .

In the process of generating information about recommended detour points, the recommended detour point extraction unit 840 first identifies the current position of the mobile object MV from the current position information.

Upon receiving the distribution data transmitted from the various distribution servers 600 in response to the distribution data request, the recommended detour point extraction unit 840 extracts the distribution data based on the map information and the hazard map information stored in the storage unit 810. Then, a recommended detour point is extracted based on the degree of accident risk when the moving body MV travels along the guidance route. Subsequently, the recommended detour point extracting unit 840 transmits information on the extracted recommended detour points to the information generation device 700 .

<Detour information generation processing>
Next, detour information generation processing executed by the processing control unit 750 will be described. When the guidance route is set, the process control unit 750 starts the detour information generation process.

When generating the detour information, the processing control unit 750 initializes the number of internal detour points (DN) to "0". Subsequently, the process control unit 750 repeats the detour information update process until the destination is reached.
<<Detour information update process>>
Upon receiving the information about the recommended detour point transmitted from the information processing device 800, the processing control unit 750 starts the detour information generation processing.

When the detour information is generated, a detour route (second route) that bypasses the new recommended detour point on the guidance route (first route) is automatically searched for. Subsequently, the processing control unit 750 presents information on the detour route that has been searched for and invitation information for selecting whether or not to select the detour route to the presentation unit 920, in addition to the guidance information on the first route described above. Let As described above, the information about the detour route includes the difference in at least one of the distance cost, time cost, toll cost, and energy cost between when the detour route is selected and when the current guidance route is maintained.

If the result of determination in step S21 is negative (step S21: N), the process of step S14 ends. Then, the process returns to step S12 in FIG. 7 described above.

If the result of determination in step S21 is affirmative (step S21: Y), the process proceeds to step S22. In this step S22, the processing control unit 110A selects a recommended detour point on the guidance route (first route) among the recommended detour points transmitted from the information processing device 300A, the sound output unit 210 and the display unit 220. It is determined whether or not there is an unpresented recommended detour point that has not been presented using . If the result of determination in step S22 is negative (step S22: N), the process of step S14 ends. Then, the process returns to step S12 in FIG.

If the result of determination in step S22 is affirmative (step S22: Y), the process proceeds to step S23. In this step S23, the processing control unit 110A presents the unpresented recommended detour point using the sound output unit 210 and the display unit 220, and presents a detour route (second route) that bypasses the recommended detour point. Explore automatically. When searching for such a detour route, the processing control unit 110A performs a search prioritizing the elements that were given priority in the search for the guide route.

The sound output unit 210 and the display unit 220 are used to present to the user. The information about the detour route includes information about the difference in at least one of distance cost, time cost, toll cost, and energy cost between when the detour route is selected and when the current guidance route is maintained. It's like

Next, in step S25, the processing control unit 110A determines whether or not a detour route has been selected. In this determination, the processing control unit 110A makes an affirmative determination that a detour route has been selected when the user who has received the invitation inputs "select" to the input unit 130. FIG. Further, when the user inputs "do not select" to the input unit 130, the processing control unit 110A makes a negative determination that the detour route has not been selected.

If the result of determination in step S25 is negative (step S25: N), the process of step S14 ends. Then, the process returns to step S12 in FIG.

On the other hand, if the result of determination in step S25 is affirmative (step S25: Y), the process proceeds to step S26. In this step S26, the processing control unit 110A adds the number of detour points (n) that can be detoured by selecting the detour route to the number of detour points (DN) included in the detour information. do.

Next, in step S27, the processing control unit 110A sets the selected detour route as a new guidance route (first route). Then, the process of step S14 ends, and the process returns to step S12 of FIG.

As shown in FIG. 10, in the process of generating information on a recommended detour point, first, in step S31, the processing control unit 310A determines whether or not the vehicle-mounted device ID and current position information have been received. If the result of determination in step S31 is negative (step S31: N), the process of step S31 is repeated.

If the result of determination in step S31 is affirmative (step S31: Y), the process proceeds to step S32. In this step S32, the processing control unit 310A acquires environment information of a predetermined range including the current position specified based on the current position information. Upon acquisition of such environmental information, the processing control unit 310A transmits to the various distribution servers 600 a distribution data request designating the identified current position and the size of the surrounding area. Then, the processing control unit 310A receives distribution data transmitted from various distribution servers 600 in response to the distribution data request.

Next, in step S33, the processing control unit 310A determines whether or not there is a recommended detour point. At the time of such determination, the processing control unit 310A, based on the distribution data, and the map information MPJ and the hazard map information HMI stored in the storage unit 320A, from the viewpoint of traffic safety, in other words, reduce the risk of accidents during traffic. Detour recommended points are extracted from the point of view. Then, the processing control unit 310A determines whether or not there is a recommended detour point based on the result of the extraction process of the recommended detour point.

If the result of determination in step S33 is negative (step S33: N), the process returns to step S31. On the other hand, if the result of determination in step S33 is affirmative (step S33: Y), the process proceeds to step S34.

In step S34, the processing control unit 310A transmits the information about the recommended detour point to the information generation device 100A having the received vehicle-mounted device ID. Then, the process returns to step S31. After that, the processing of steps S31 to S34 is repeated.

《Update processing of total detour information》
Next, update processing of total detour information executed by the processing control unit 310A will be described.

In updating the total detour information, as shown in FIG. 11, first, in step S41, the processing control unit 310A determines whether or not the vehicle-mounted device ID and the detour information have been received. If the result of determination in step S41 is negative (step S41: N), the process of step S41 is repeated.

If the result of determination in step S41 is affirmative (step S41: Y), the process proceeds to step S42. In this step S42, the processing control unit 310A updates the total detour information DTI stored in the storage unit 320A. At the time of such updating, the processing control unit 310A adds the number of detour points (DN _j ) included in the received detour information to the number of detour points in the storage unit 320A associated with the received vehicle-mounted device ID (CID _j ). update the total number of detour points (DN _j ) stored in .

Then, the process returns to step S41. Thereafter, the processes of steps S41 and S42 are repeated.

Therefore, the user of the vehicle CR can determine whether or not to select a detour route after grasping the various costs that increase.

Further, in the first embodiment, upon receiving the current position information of the vehicle CR transmitted from the information generating device 100A, the processing control unit 310A detects the risk of an accident when the vehicle CR passes around the current position of the vehicle CR. The point specified based on is extracted as a detour recommended point. Then, the processing control unit 310A transmits information on the extracted recommended detour point to the information generating device 100A.

Further, in the first embodiment, when the detour information transmitted from the information generation device 100A is received, the processing control unit 310A causes the information reflecting the detour information to be stored in the storage unit 320A in association with the identification information of the vehicle CR. . In addition, in the first embodiment, as the information reflecting the detour information, a total value of the number of detour points in a period of a predetermined period length is adopted.

In this case, for example, by setting a large profit for the vehicle user when traveling on a detour route that greatly increases the cost, it is possible to use the vehicle even if the detour greatly increases the cost. It is possible to motivate the person to bypass the recommended detour point.

In addition, the information on the recommended detour point includes the degree of accident risk when the vehicle CR passes through the recommended detour point. The presentation may include the degree of risk. In this case, the user of the vehicle can determine whether or not to select the detour route after grasping the accident risk.

Furthermore, when the degree of accident risk is included in the information on the recommended detour point, the information reflecting the detour information is set to a detour point value that increases as the degree of accident risk in a predetermined period of time increases. may be the aggregate value of In this case, for example, if the higher the detour point value is, the greater the profit for the vehicle user is set, the vehicle user is detoured from the recommended detour point according to the degree of accident risk. It is possible to give motivation to do.

It is also assumed that a guidance route for the vehicle CR has already been set, and that the terminal device 100B is providing guidance when traveling along the guidance route.

<<Detour information generation process>>
First, the detour information generation processing executed by the processing control unit 310B will be described. This process starts when the guidance route is set.

As shown in FIG. 15, the processing control unit 310B first initializes the number of detour points (DN) to "0" in step S51 when generating the detour information. Subsequently, in step S52, the processing control unit 310B identifies the current position of the vehicle CR based on the latest current position information.

Next, in step S53, the processing control unit 310B determines whether or not the vehicle CR has arrived at the destination. If the result of determination in step S53 is affirmative (step S13: Y), the process proceeds to step S55, which will be described later.

If the result of determination in step S53 is negative (step S53: N), the process proceeds to step S54. In this step S54, the processing control unit 310B performs a detour information update process. Then, the process returns to step S52 described above.

Details of the detour information updating process executed in step S54 will be described later.

After that, the processes of steps S52 to S54 are repeated until the result of determination in step S53 becomes affirmative. When the vehicle CR arrives at the destination and the result of the determination in step S53 becomes affirmative (step S53: Y), the detour information generation processing for this time ends. Then, the process proceeds to step S55.

In step S55, the processing control unit 310B executes update processing of the total number of detour points corresponding to the vehicle-mounted device ID, as in the case of step S42 described above. As a result, the total detour information DTI stored in the storage unit 120B is updated.

<<Detour information update process>>
Next, the detour information updating process executed in step S54 will be described.

When updating the detour information, as shown in FIG. 16, first, in step S61, the processing control unit 310B determines whether or not there is an unnotified detour recommended point on the guidance route. In making such a determination, the processing control unit 310B first performs processing for generating information on recommended detour points, as in the case of the processing control unit 110A described above. Then, based on the result of the generation process, the process control unit 310B determines whether or not there is an unnotified detour recommended point on the guide route.

If the result of determination in step S61 is negative (step S61: N), the process of step S54 ends. Then, the process returns to step S52 in FIG. 15 described above.

If the result of determination in step S61 is affirmative (step S61: Y), the process proceeds to step S62. In this step S62, the processing control unit 310B searches for a detour route (second route) that bypasses the unpresented recommended detour point in the same manner as the processing control unit 110A described above.

Next, in step S63, the processing control unit 310B generates detour route information and transmits the generated detour route information to the terminal device 100B.

Generated as detour route information including Then, the processing control unit 310B transmits the generated detour route information to the terminal device 100B.

Next, in step S64, the processing control unit 310B determines whether or not a detour route has been selected. When the process control unit 310B receives the fact that the user who has been invited to select has input "select" into the input unit 130, the processing control unit 310B makes a positive determination that the detour route has been selected. Further, when the processing control unit 310B receives that the user has input "do not select" to the input unit 130, the processing control unit 310B makes a negative determination that the detour route has not been selected.

If the result of determination in step S64 is negative (step S64: N), the process of step S54 ends. Then, the process returns to step S52 in FIG.

On the other hand, if the result of determination in step S64 is affirmative (step S64: Y), the process proceeds to step S65. In this step S65, the processing control unit 310B adds the number of detour points (n) that can be detoured by selecting the detour route to the number of detour points (DN) included in the detour information. do.

Next, in step S66, the processing control unit 310B sets the selected detour route as a new guidance route (first route). Then, the process of step S54 ends, and the process returns to step S52 of FIG.

<<Detour route selection process>>
Next, a detour route selection process executed by the processing control unit 110B will be described. This detour route selection process starts when the detour route information transmitted from the information generating device 300B is received.

17, in step S71, the processing control unit 110B displays the detour route information to the user using the sound output unit 210 and the display unit 220. present. As in the case of the first embodiment described above, the detour route information includes the distance cost, time cost, toll cost, and energy cost when the detour route is selected and when the current guidance route is maintained. is adapted to include information relating to at least one cost difference of .

Next, in step S72, the processing control unit 110B determines whether or not a detour route has been selected. In this determination, the processing control unit 110B determines that the detour route has been selected when the solicited user inputs "select" to the input unit 130, as in the case of the first embodiment described above. affirmative judgment of Further, when the user inputs "do not select" to the input unit 130, the processing control unit 110B makes a negative determination that the detour route has not been selected.

If the result of determination in step S72 is affirmative (step S72: Y), the process proceeds to step S73. In this step S73, the processing control unit 110B transmits a detour route selection designation (that is, "to select") to the information generation device 300B. Then, the detour route selection process for this time ends.

If the result of determination in step S72 is negative (step S72: N), the process proceeds to step S74. In this step S74, the processing control unit 110B transmits a detour route non-selection designation (that is, "do not select") to the information generating device 300B. Then, the detour route selection process for this time ends.

As described above, in the second embodiment, the processing control unit 310B of the information generating device 300B is the point specified based on the current position of the vehicle CR and based on the accident risk when the vehicle CR passes. A recommended detour point is extracted, and information on the extracted recommended detour point is transmitted to the terminal device 100B arranged in the vehicle CR. Then, when it is determined that the vehicle CR has detoured around the recommended detour point based on the current position of the vehicle CR, the processing control unit 310B sends information reflecting detour information indicating that the vehicle CR has detoured around the recommended detour point, It is stored in the storage unit 320B in association with the identification information of the vehicle CR.

In addition, in the second embodiment, when presenting the second route, the processing control unit 310B further provides information about the difference in at least one of distance cost, time cost, toll cost and energy cost from the first route. present it. Therefore, the user of the vehicle CR can determine whether or not to select a detour route after grasping the various costs that increase.

Further, in the second embodiment, when the current position information of the vehicle CR transmitted from the terminal device 100B is received, the processing control unit 310B detects the accident risk when the vehicle CR passes around the current position of the vehicle CR. The point specified by the method is extracted as a recommended detour point. Then, based on the detour information including the extracted number of detour recommended detour points, the processing control unit 310B causes the storage unit 320B to store the information reflecting the detour information in association with the identification information of the vehicle CR. .

Therefore, cooperation between the terminal device 100B and the information generation device 300B can contribute to effective operation for motivating the user of the vehicle CR to select the detour route.

In addition, since the terminal device 100B does not need to have a travel route searching function, a map matching function, or the like, the processing in the terminal device 100B can be simplified. Therefore, as the terminal device 100B, for example, a small portable terminal device such as a user's smart phone can be used. In such a case, it is possible to tally the number of recommended detour points for each owner of the portable terminal device. For this reason, for example, users can count the number of detours to recommended detour points when driving a rental car, so that each user is motivated to detour from recommended detour points regardless of the vehicle used. can contribute to the operation of

<Modification of Second Embodiment>
Various modifications to the second embodiment are possible. For example, in the above-described second embodiment, the same modification as in the case of the above-described first embodiment can be appropriately performed.

[Third embodiment]
Next, a third embodiment of the present invention will be described mainly with reference to FIGS. 18-22.

<Configuration>
FIG. 18 shows the configuration of an information generation system 400C according to the third embodiment. As shown in FIG. 18, the information generation system 400C differs from the first embodiment in that it includes an information generation device 100C instead of the information generation device 100A, and that the vehicle CR has a sensor unit 230 The difference is that a sensor unit 230C is arranged instead of .

In addition to the sensors included in the sensor unit 230, the sensor unit 230C further includes an ignition state sensor that detects the ignition state (“ON” or “OFF”), a door open/close sensor that detects door opening/closing, and the like. . A detection result by the sensor unit 230C is sent to the information generation device 100C.

<<Information Generating Device 100C>>
As shown in FIG. 19, the information generation device 100C differs from the information generation device 100A described above in that it includes a processing control unit 110C instead of the processing control unit 110A.

The processing control unit 110C described above controls the entire information generation device 100C. This processing control unit 110C is different from the information generating device 100A described above in that it performs detour information generation processing regardless of whether or not a guidance route is set. The following description will focus mainly on these differences.

<Action>
Next, the operation of the information generation system 400C configured as described above will be described, mainly focusing on the detour information generation processing executed by the processing control unit 110C of the information generation device 100C.

It is assumed that the sensor unit 230C and the GPS receiving unit 240 have already started operating and are sequentially sending detection results to the information generating device 100C. It is also assumed that the processing control unit 110C sequentially sends the local position information to the information processing device 300A.

In the detour information generation process, as shown in FIG. 20, first, in step S81, the processing control unit 110C causes the vehicle CR to move based on the temporal change in the current position (or vehicle speed) of the vehicle CR. Determine whether it has started. If the result of determination in step S81 is negative (step S81: N), the process of step S81 is repeated.

If the result of determination in step S81 is affirmative (step S81: Y), the process proceeds to step S82. In this step S82, the processing control unit 110C identifies the current position of the vehicle CR based on the latest current position information. Subsequently, at step S83, the processing control unit 110C stores the current position specified at step S82 in the storage unit 120A as the departure point position.

Next, in step S84, the processing control unit 110C identifies the current position of the vehicle CR based on the latest current position information. Subsequently, in step S85, the processing control unit 110C determines whether or not the information regarding the recommended detour point has been received. If the result of determination in step S85 is negative (step S85: N), the process proceeds to step S87, which will be described later.

If the result of determination in step S85 is affirmative (step S85: Y), the process proceeds to step S86. In this step S86, the processing control unit 110C refers to the current position of the vehicle CR and the map information MPI stored in the storage unit 120A, and outputs the information about the recommended detour point to the sound output unit 210 and the display unit 220. be used and presented to the user. In addition, the processing control unit 110C stores information on recommended detour points in the storage unit 120A.

Next, in step S87, the processing control unit 110C determines whether or not the vehicle has finished running. At the time of such determination, in the third embodiment, the processing control unit 110C determines whether or not the vehicle has finished traveling by determining whether or not the ignition state has become "OFF".

If the result of determination in step S87 is negative (step S87: N), the process returns to step S84. After that, the processing of steps S84 to S87 is repeated until the result of determination in step S87 becomes affirmative.

When the vehicle CR finishes running and the result of determination in step S87 becomes affirmative (step S87: Y), the process proceeds to step S88. In step S88, the processing control unit 110C performs detour information calculation processing. After that, the process of generating the detour information this time ends.

<<Detour information calculation process>>
Next, the detour information calculation process executed in step S88 will be described. In the detour information calculation process, as shown in FIG. 21, first, in step S91, the processing control unit 110C specifies the position of the point where the current travel of the vehicle CR ends as the arrival point position.

Subsequently, in step S92, the processing control unit 110C searches for a standard route from the departure point to the arrival point. When searching for such a standard route, the processing control unit 110C performs a search prioritizing the elements (distance cost, time cost, toll cost, energy cost, etc.) prioritized by the user when searching for past travel routes.

Next, in step S93, the processing control unit 110C determines whether or not there is a recommended detour point on the standard route. If the result of determination in step S93 is negative (step S93: N), the process of step S88 ends. Then, the current detour information generation processing ends.

If the result of determination in step S93 is affirmative (step S93: Y), the process proceeds to step S94. In this step S94, the processing control unit 110C counts the number of recommended detour points (DN) on the standard route detoured by the actual travel route.

Next, in step S95, the processing control unit 110C generates detour information based on the counting result in step S94. Then, the processing control unit 110C transmits the generated detour information together with the vehicle-mounted device ID to the information processing device 300A.

When the process of step S95 ends, the process of step S88 ends. Then, the current detour information generation processing ends.

Upon receiving the vehicle-mounted device ID and the detour information, in the information processing device 300A, the processing control unit 310A executes update processing of the total detour information, as in the case of the first embodiment described above.

Note that FIG. 22 shows a display example displayed by the process of step S86 described above. In FIG. 22, the current position is indicated by ▴.

As described above, in the third embodiment, when receiving from the information processing device 300A the information on the recommended detour point, which is the point specified based on the accident risk when the vehicle CR travels, the information generation device 100C: The processing control unit 110C causes the user of the vehicle CR to present information about the recommended detour point. Then, when the current travel of the vehicle CR is completed, a search is made for a standard route from the departure point to the arrival point of the current travel. Subsequently, the processing control unit 110C generates detour information indicating that the recommended detour point is detoured when the travel from the departure point to the arrival point this time detours the recommended detour point included in the standard route. Then, the processing control unit 110C generates the generated detour information and transmits it to the information processing device 300A.

Therefore, according to the third embodiment, it is possible to contribute to the operation for giving motivation to the user of the vehicle CR to select the detour route.

In addition, in the third embodiment, upon receiving the current position information of the vehicle CR transmitted from the information generating device 100C, the processing control unit 310A detects the risk of an accident when the vehicle CR travels around the current position of the vehicle CR. The point specified based on is extracted as a detour recommended point. Then, the processing control unit 310A transmits information on the extracted recommended detour point to the information generation device 100C.

In addition, in the third embodiment, when the detour information transmitted from the information generation device 100C is received, the processing control unit 310A stores the information reflecting the detour information in the storage unit 320A in association with the identification information of the vehicle CR. . In addition, in the third embodiment, as the information reflecting the detour information, a total value of the number of detour points in a period of a predetermined period length is adopted.

Therefore, cooperation between the information generation device 100C and the information processing device 300A can contribute to effective operation for motivating the user of the vehicle CR to select the detour route.

[Modification of the third embodiment]
Various modifications to the third embodiment are possible.

For example, in the above-described third embodiment, the same modification as in the case of the above-described first embodiment can be appropriately performed.

In the above-described third embodiment, the standard route search is performed by prioritizing the elements (distance cost, time cost, toll cost, energy cost, etc.) prioritized by the user when searching for past travel routes. . On the other hand, if there is a travel route that has been used regularly from the departure point to the arrival point in the past, this travel route may be set as the standard route. Specifically, the storage unit of the information generating device sequentially stores the departure point, the arrival point, and the travel route therebetween. Then, if the departure and arrival points that are the same as this time or are located close to each other (within a predetermined distance) are stored, the actual travel rate during this period is higher than a predetermined reference value (for example, a probability of 90% or more). ), the route may be set as a standard route. In this case, it is possible to determine whether or not the user intentionally bypasses the recommended detour point by using the route that the user usually uses as the standard route.

Further, in the third embodiment described above, when the ignition state becomes "OFF", it is determined that the vehicle has finished traveling, and detour information is generated. On the other hand, when the arrival point was located at or near a facility outside the road and the door was open, the user intentionally stopped at the facility instead of going straight to the final destination. Therefore, it is highly probable that the driver accidentally bypassed the recommended detour point. Then, detour information associated with the accidental detour may not be generated.

Also, the third embodiment can be modified in the same manner as the modification of the second embodiment with respect to the first embodiment.

[Fourth embodiment]
Next, a fourth embodiment of the present invention will be described mainly with reference to FIGS. 23-28.

<Configuration>
FIG. 23 shows the configuration of an information generation system 400D according to the fourth embodiment. As shown in FIG. 23, the information generation system 400D differs from the first embodiment in that it includes an information generation device 100D instead of the information generation device 100A, and an information processing device 300A instead of the information processing device 300A. The difference is that a processing device 300D is provided.

<<Configuration of Information Generating Device 100D>>
As shown in FIG. 24, the information generating device 100D described above differs from the information generating device 100A described above in that it includes a processing control unit 110D instead of the processing control unit 110A.

The processing control unit 110D described above comprehensively controls the entire information generation device 100D. This processing control unit 110D differs from the above-described processing control unit 110A in that it performs non-retour information generation processing. In addition, when the vehicle CR starts traveling away from the set guidance route, the information generation device 100D automatically performs route search again, and uses the searched route as a new guidance route. By using the sound output unit 210 and the display unit 220, guidance information for traveling along the new guidance route is presented to the user of the vehicle CR.

The details of the non-retour information generation process will be described later.

<<Configuration of Information Processing Device 300D>>
As shown in FIG. 25, the information processing apparatus 300D is different from the information processing apparatus 300A described above in that it includes a processing control unit 310D instead of the processing control unit 310A and a storage unit 320A instead of the storage unit 320A. It differs in that it includes a unit 320D.

Here, the processing control unit 310D differs from the processing control unit 310A in that it updates total non-circumvention information, which will be described later, based on the non-circumvention information transmitted from the information generating device 100D. Also, the storage unit 320D differs from the storage unit 320A in that total non-detour information NDTI is stored instead of total detour information DTI, as shown in FIG. As shown in FIG. 27, the total non-circumvention information NDTI is a total period of a predetermined period length (for example, "one month") associated with the vehicle-mounted device (information generating device) ID (CID _j ). It is information on the total number of non-detour points up to the present time (total number of non-detour points: TNDN _j )

<Action>
Next, the operation of the information generation system 400D configured as described above will be described, mainly focusing on the non-retour information generation processing executed by the processing control unit 110D of the information generation device 100D.

It is assumed that the sensor unit 230 and the GPS receiving unit 240 have already started operating, and the processing control unit 110D is sequentially sending the local position information to the information processing device 300D. It is also assumed that the guidance route for the vehicle CR has already been set, and the information generating device 100D provides guidance for traveling along the guidance route.

Further, it is assumed that the processing control unit 310D of the information processing device 300D is executing the processing of generating information on the recommended detour points similar to the case of the processing control unit 310A described above. Then, the processing control unit 110D of the information generating device 100D performs the process of presenting the information on the recommended detour point transmitted from the information processing device 300D, as in the case of the information generating device 100C described above.

<<Generation of non-detour information>>
The process of generating non-detour information is started when a guidance route is set.

As shown in FIG. 28, the processing control unit 110D first initializes the number of non-detour points (NDN) to "0" in step S101 during the non-detour information generation process. Subsequently, in step S102, the processing control unit 110D identifies the current position of the vehicle CR based on the latest current position.

Next, in step S103, the processing control unit 110D determines whether or not the vehicle CR has arrived at the destination. If the result of determination in step S103 is negative (step S103: N), the process proceeds to step S104.

In step S104, the processing control unit 110D determines whether or not the vehicle CR has passed through the recommended detour point. If the result of determination in step S104 is negative (step S104: N), the process returns to step S102.

If the result of determination in step S104 is affirmative (step S104: Y), the process proceeds to step S105. In step S105, the processing control unit 110D calculates a new number of non-detour points (NDN) by adding "1" to the existing number of non-detour points (NDN).

After the process of step S105 is completed, the process returns to step S102. Then, the processing of steps S102 to S105 is repeated until the result of determination in step S103 becomes affirmative.

When the vehicle CR arrives at the destination and the result of determination in step S103 becomes affirmative (step S103: Y), the process proceeds to step S106. In step S106, the processing control unit 110D generates non-detour information including the number of non-detour points (NDN) at that time, and transmits the generated non-detour information together with the vehicle-mounted device ID to the information processing device 300D.

Upon receiving the non-circumvention information transmitted from the information generating device 100D, the processing control unit 310D updates the aggregate non-circumvention information NTDI stored in the storage unit 320D. Upon such updating, the processing control unit 310D adds the number of non-detour points (NDN _j ) included in the received detour information. With this addition, the processing control unit 310D updates the total number of non-detour points (TNDN _j ) stored in the storage unit 320D associated with the received vehicle-mounted device ID (CID _j ).

As described above, in the fourth embodiment, when the information regarding the recommended detour point, which is the point specified based on the accident risk when the vehicle CR travels, is received from the information processing device 300D, the information generating device 100D performs The processing control unit 110D causes the user of the vehicle CR to present information about the recommended detour point. Then, when the vehicle CR has passed through the recommended detour point, the information generation device 100D generates non-detour information indicating that the vehicle has passed through the recommended detour point. Then, the processing control unit 110D transmits the generated detour information to the information processing device 300D.

Therefore, according to the fourth embodiment, it is possible to contribute to the operation for giving motivation to the user of the vehicle CR to select the detour route. As a specific example of giving the user of the vehicle CR a motivation to select a detour route, an extra premium for the next automobile insurance premium is provided according to the track record of not detouring the recommended detour point with a relatively high accident risk. mentioned.

In addition, in the fourth embodiment, upon receiving the current position information of the vehicle CR transmitted from the information generating device 100D, the processing control unit 310D detects the risk of an accident when the vehicle CR passes around the current position of the vehicle CR. The point specified based on is extracted as a detour recommended point. Then, the processing control unit 310D transmits information on the extracted recommended detour point to the information generation device 100D.

Further, in the fourth embodiment, when the non-detour information transmitted from the information generation device 100D is received, the processing control unit 310D stores the information reflecting the non-detour information in the storage unit 320D in association with the identification information of the vehicle CR. Memorize. In addition, in the fourth embodiment, as the information reflecting the non-detour information, a total value of the number of non-detour points in a period of a predetermined period length is adopted.

Therefore, cooperation between the information generation device 100D and the information processing device 300D can contribute to effective operation for motivating the user of the vehicle CR to select the detour route.

[Modification of the fourth embodiment]
Various modifications to the fourth embodiment are possible.

For example, in the above fourth embodiment, it is assumed that the guide route is set. On the other hand, if no guidance route is set, non-detour information may be generated for each travel from the departure point to the arrival point, as in the case of the third embodiment described above.

In addition, the information on the recommended detour point includes the degree of accident risk when the vehicle CR passes through the recommended detour point (that is, the degree of recommendation of the detour). You may make it present|present by matching a degree. In this case, the user of the vehicle can determine whether or not to bypass the recommended detour point based on the detour recommendation level.

Furthermore, when the detour recommendation level is included in the information about the detour recommended points, the information reflecting the non-detour information is used as a detour point value that increases as the detour recommendation level increases during a predetermined period of time. A total value may be used. In this case, for example, the higher the detour point value, the greater the disadvantage for the vehicle user. It becomes possible to give motivation to detour.

Also, the fourth embodiment can be modified in the same manner as the modification of the second embodiment with respect to the first embodiment.

In the first to fourth embodiments, the number of recommended detour points detoured or the number of recommended detour points passed through is counted. On the other hand, the number of detour recommended detour points, or the aggregate value of the ratio of the number of detour recommended detour points passed and the extracted number of detour recommended points, is used to determine the profit obtained by the vehicle user. can be
