[1.2. Configuration of mobile body 12]
The configuration of the moving body 12 will be explained using FIG. 2. The moving body 12 is, for example, a vehicle. In the first embodiment, a two-wheeled vehicle is assumed as the moving object 12. The mobile body 12 includes a sensor group 26 , a navigation device 28 , a control device 30 , a communication device 32 , and a notification device 34 . In this specification, as shown in FIG. 1, among the moving objects 12, the moving object 12 that transmits the behavior occurrence information 18 is referred to as the first moving object 12a, and the moving object 12 that receives the notification information 20 is referred to as the first moving object 12a. 2 mobile body 12b. However, the moving body 12 is not distinguished in advance into either the first moving body 12a or the second moving body 12b. All the moving bodies 12 become the first moving bodies 12a when transmitting the behavior occurrence information 18, and become the second moving bodies 12b when receiving the notification information 20.

The sensor group 26 includes, for example, a gear position sensor 36, a speed sensor 38, a brake sensor 40, a yaw rate sensor 42, a steering angle sensor 44, a fuel sensor 46, and the like. The gear position sensor 36 detects the gear position (shift position) of the moving body 12. The speed sensor 38 detects the traveling speed of the moving body 12. The brake sensor 40 detects whether a brake operator (pedal, lever, etc.) of the moving body 12 is being operated. Yaw rate sensor 42 detects the yaw rate of moving body 12. The steering angle sensor 44 detects the steering angle of the moving body 12. The fuel sensor 46 detects the remaining amount of fuel in the moving object 12 . Note that the sensor group 26 may include other sensors. Each sensor outputs detected information to the control device 30.

The navigation device 28 detects the position of the mobile object 12 using a satellite positioning system or the like. The navigation device 28 also creates a planned travel route to the destination. The navigation device 28 outputs various information to the control device 30.

The control device 30 is configured by, for example, an ECU. The control device 30 includes, in addition to input/output devices (not shown), a calculation section 50 made up of a processor such as a CPU, and a storage section 52 made up of a RAM, ROM, etc.

The calculation unit 50 functions as an acquisition unit 54, a reception unit 56, a determination unit 58, a transmission unit 60, and a notification unit 62 when a processor executes a program. The acquisition unit 54 acquires various information from the sensor group 26 and the navigation device 28. The receiving unit 56 receives various information transmitted from the information sharing device 14 or other moving objects 12 or the like. The determining unit 58 determines whether a predetermined behavior associated with the weather condition has occurred. The transmitting unit 60 transmits various information to the information sharing device 14 or other moving body 12, etc. The notification unit 62 outputs a notification instruction to the notification device 34 based on the notification information 20 transmitted by the information sharing device 14.

The communication device 32 includes a communication circuit, an antenna, and the like. The communication device 32 performs bidirectional communication with the information sharing device 14 and the like via the information communication network 16. The communication device 32 may be installed in the mobile body 12 in advance, or may be a portable communication terminal brought into the mobile body 12, such as a smartphone.

The notification device 34 includes a display and a speaker (not shown). The notification device 34 notifies the driver of the notification information 20 in response to the notification instruction output by the calculation unit 50.

[1.3. Behavior of moving object 12]
The predetermined behavior is a behavior that is likely to occur in the moving body 12 under predetermined weather conditions. For example, there is a high possibility that a two-wheeled vehicle will exhibit a behavior called ``wobble'' under weather conditions such as ``crosswind.'' Furthermore, when the weather condition is "crosswind," there is a high possibility that a two-wheeled vehicle will exhibit a behavior called "wind-resistant driving." As a first example of wind-resistant driving, the driver sets the gear ratio one step lower than usual. As a second example of wind-resistant driving, the driver drives the two-wheeled vehicle while operating the rear brake. As a third example of wind-resistant driving, the driver drives the two-wheeled vehicle straight while steering in the windward direction.

For example, the behavior of wobbling is determined based on the detected value of the yaw rate sensor 42. The first example of wind-resistant driving is determined based on the detected value of the gear position sensor 36. The second example of wind-resistant driving is determined based on the detected values of the brake sensor 40 and the speed sensor 38. The third example of wind-resistant driving is determined based on the detected value of the steering angle sensor 44 and the traveling trajectory measured by the navigation device 28.

Therefore, the following determination information 66 is recorded in the recording unit 52. As an example, the determination information 66 includes behavior information 74 indicating the wobbling of the moving body 12, weather condition information 76 indicating the weather condition of a crosswind that causes the wobbling, and a reference value 78 indicating the yaw rate when the wobbling occurs. Connect. In addition to the yaw rate, the reference value 78 may be set, such as the relationship between the gear position and the travel distance, the travel distance and speed with the brake on, or the relationship between the steering angle and the straight travel distance.

[1.4. Configuration of information sharing device 14]
The configuration of the information sharing device 14 will be explained using FIG. 3. The information sharing device 14 is a server that provides information sharing services. The information sharing device 14 has a calculation unit 82 configured by a processor such as a CPU, and a recording unit 84 configured by a RAM, ROM, etc.

The calculation unit 82 functions as a reception unit 86, a determination unit 88, and a transmission unit 90 when a processor executes a program. The receiving unit 86 receives various information transmitted from the mobile body 12 (first mobile body 12a) and the like. The determining unit 88 determines broadcast information 20 and incidental information 22 to be transmitted to the mobile body 12 (second mobile body 12b), and determines the mobile body 12 (second mobile body 12b) to which the broadcast information 20 and incidental information 22 are transmitted. The mobile object 12b) is determined. The transmitter 90 transmits various information to the mobile body 12 (second mobile body 12b) and the like.

The recording unit 84 stores in advance first relational information 92, second relational information 94, and map information 96 in addition to the program executed by the processor.

The first relationship information 92 is information in which the behavior information 74, the weather condition information 76, and the notification information 20 are linked to each other. As an example, the first related information 92 includes behavior information 74 indicating the wobbling of the moving body 12, weather condition information 76 indicating the weather condition of a crosswind that causes the wobbling, and notification information 20 indicating a notification item that calls attention to the crosswind. Link it with.

The second relationship information 94 is information that associates the first moving object information 98 and the second moving object information 100 with each other. The first moving body information 98 indicates the unique information 64 of the first moving body 12a. The second moving body information 100 indicates unique information 64 of the second moving body 12b. In the second relationship information 94, the first moving object information 98 and the second moving object information 100 have a predetermined relationship. For example, the predetermined relationship is set in association with weather conditions. As a specific example, the first moving object information 98 and the second moving object information 100 are linked in terms of weight based on the weather condition of crosswind. In this case, the weight indicated by the second moving body information 100 is lighter than the weight indicated by the first moving body information 98. As another specific example, the first moving object information 98 and the second moving object information 100 are linked in terms of type based on the weather condition of rain. In this case, the type indicated by the first moving body information 98 and the type indicated by the second moving body information 100 are the same.

[1.5. Operation of first moving body 12a]
As described above, the mobile object 12 transmits probe data to the information sharing device 14. The mobile body 12 (first mobile body 12a) performs an information transmission process shown in FIG. 4 in addition to the process of transmitting probe data. The information transmission process is executed at predetermined time intervals while the moving body 12 is traveling.

In step S1, the determination unit 58 of the moving object 12 determines whether a predetermined behavior has occurred by comparing various information detected by the sensor group 26 with each reference value 78 of the determination information 66. If the predetermined behavior occurs (step S1: YES), the process moves to step S2. On the other hand, if the predetermined behavior has not occurred (step S1: NO), the series of processes ends.

In step S2, the transmitter 60 of the mobile object 12 creates behavior occurrence information 18 indicating that a predetermined behavior has occurred. The transmitter 60 then transmits the behavior occurrence information 18 to the information sharing device 14. After the process of step S2 is executed, the series of processes ends.

[1.6. Operation of information sharing device 14]
As described above, the information sharing device 14 receives the probe data transmitted by the mobile object 12. The information sharing device 14 performs the information sharing process shown in FIG. 5 separately from the process of receiving probe data. The information sharing process is executed at predetermined intervals.

In step S11, the receiving unit 86 of the information sharing device 14 determines whether or not the behavior occurrence information 18 transmitted by the moving object 12 (first moving object 12a) has been received. When the receiving unit 86 receives the behavior occurrence information 18 (step S11: YES), the process moves to step S12. On the other hand, if the receiving unit 86 has not received the behavior occurrence information 18 (step S11: NO), the series of processes ends.

In step S12, the determining unit 88 of the information sharing device 14 determines the mobile body 12 (second mobile body 12b) to which the broadcast information 20 is to be transmitted. The determining unit 88 sets a predetermined area based on the point where the predetermined behavior occurs in the first moving object 12a (behavior occurrence point), and selects the moving object 12 traveling in that area as a candidate for the second moving object 12b. do. The determining unit 88 knows the traveling position of the second moving body 12b based on the probe data. Further, the determining unit 88 collates any predetermined information (type information 68, etc.) included in the unique information 64 of the behavior occurrence information 18 with the first moving object information 98 of the second related information 94, and selects the matching first moving object information 98. The second mobile body information 100 that is linked to the first mobile body information 98 is specified. Then, the determining unit 88 selects, from among the candidates for the second moving body 12b, the second moving body 12b that matches the predetermined information (type information 68, etc.) indicated by the specified second moving body information 100. The moving body 12b is determined. After the process of step S12 is executed, the process moves to step S13.

In step S13, the determining unit 88 determines the broadcast information 20 to be transmitted to the second mobile body 12b. The determining unit 88 compares the behavior information 74 of the behavior occurrence information 18 with the behavior information 74 of the first related information 92, and determines the notification information 20 linked to the matching behavior information 74 as the notification information 20 to be transmitted. .

Further, in step S13, the determining unit 88 determines the incidental information 22 to be transmitted to the second mobile body 12b according to the weather conditions. For example, when the weather condition is a crosswind, increasing the weight of the moving body 12 can suppress wobbling. Therefore, the determining unit 88 may decide to recommend refueling. Further, the determining unit 88 may decide to recommend a changed route to avoid the point where the behavior occurs.

In step S14, the transmitting unit 90 of the information sharing device 14 creates incidental information 22 to be transmitted to the second mobile body 12b based on the determination result of the determining unit 88. For example, the transmitting unit 90 extracts the second moving object 12b whose scheduled travel route includes the point where the behavior occurred, and uses the map information 96 to recreate the planned traveling route of the second mobile object 12b. Then, the transmitter 90 transmits the created incidental information 22 and the broadcast information 20 determined in step S13 to the second mobile object 12b determined in step S12. After the process of step S14 is executed, the series of processes ends.

[1.7. Operation of second moving body 12b]
The mobile body 12 (second mobile body 12b) performs the following notification process. The receiving unit 56 of the mobile body 12 (second mobile body 12b) to which the broadcast information 20 is to be transmitted receives the broadcast information 20 and the incidental information 22 transmitted by the information sharing device 14. The receiving unit 56 of the mobile object 12 outputs a notification instruction to the notification device 34 based on the notification information 20 and the incidental information 22. The notification device 34 displays information according to the contents of the notification information 20 and the incidental information 22 on a display, and also outputs it from a speaker.

Below, the processing of steps S22 to S24, which is unique to the second embodiment, will be explained.

When the process moves from step S21 to step S22, the comparison unit 120 estimates weather conditions corresponding to the predetermined behavior that has occurred. The comparison unit 120 compares the behavior information 74 of the behavior occurrence information 18 with the behavior information 74 of the first relationship information 92 and identifies weather condition information 76 that is linked to the behavior information 74 that matches. The comparison unit 120 then takes the weather conditions indicated by the specified weather condition information 76 as the estimation result. After the process of step S22 is executed, the process moves to step S23.

In step S23, the comparison unit 120 receives the weather information 112 of the travel point of the first mobile body 12a from among the weather information 112 transmitted by the weather server 110. After the process of step S23 is executed, the process moves to step S24.

In step S24, the comparison unit 120 compares the weather conditions estimated in step S22 and the weather indicated by the weather information 112 received in step S23, and determines whether they are the same. If both are the same (step S24: YES), the process moves to step S25. In this case, the determining unit 88 of the information sharing device 14 determines the mobile body 12 (second mobile body 12b) to which the broadcast information 20 is to be transmitted. On the other hand, if both are not the same (step S24: NO), the series of processes ends.
