[0010] <Embodiment 1> FIG. 1 is a diagram showing the configuration of a travel support system according to the first embodiment. This travel support system includes an information collection system 10 constructed in a server 100, an attention-requiring situation indicating device 20 mounted on a vehicle 200 which is a moving body, and a travel support device 30 mounted on a vehicle 300 which is a moving body. Hereinafter, a user of the attention-requiring situation indicating device 20 is referred to as a "notifier", and a vehicle 200 equipped with the attention-requiring situation indicating device 20 is referred to as a "notifier vehicle". In addition, a user of the travel support device 30 is referred to as a "client", and a vehicle 300 equipped with the travel support device 30 is referred to as a "client vehicle".

[0011] In the following embodiment, the moving body on which the attention-requiring situation indicating device 20 and the moving assistance device 30 are mounted is a vehicle, but there is no restriction on the type of moving body, and it may be any type, such as a motorcycle, bicycle, pedestrian, ship, airplane, helicopter, etc. Therefore, "moving assistance" in the following description can be read as "driving assistance," "running assistance," "walking assistance," "piloting assistance," "flight assistance," etc., depending on the type of moving body.

[0012] The caution-required situation indication device 20 generates caution-required situation indication information including information on a caution-required situation encountered while traveling of the pointer vehicle 200, which has been pointed out by the pointer, who is the driver of the pointer vehicle 200, and a pointer ID, which is an identifier of the pointer, and transmits the caution-required situation indication information to the information collection system 10.

[0013] The information collection system 10 collects the attention-requiring situation indication information transmitted from the attention-requiring situation indication device 20, and creates an attention-requiring situation model, which is information that models the attention-requiring situation based on the collected attention-requiring situation indication information. The information collection system 10 also stores the created attention-requiring situation model, and delivers the attention-requiring situation model to the mobility support device 30 in response to a request from the mobility support device 30.

[0014] The mobility support device 30 provides mobility support for the client, i.e., driving support for the client vehicle 300, based on the caution-required situation model delivered from the information collection system 10. Specifically, when the situation around the client vehicle 300 becomes close to the caution-required situation model, the mobility support device 30 determines that the client vehicle 300 is in a caution-required situation, and notifies the client, who is the driver of the client vehicle 300, of the caution-required situation.

[0015] Furthermore, the client vehicle 300 evaluates the validity of the attention-required situation model depending on whether or not the notification contributed to the user's safety, and transmits the evaluation result (hereinafter also referred to as "validity evaluation result") to the information collection system 10. Specifically, when the travel assistance device 30 determines that the notification of the attention-required situation contributed to the user's safety, it evaluates the attention-required situation model corresponding to the attention-required situation as "valid," and when it determines that the notification of the attention-required situation did not contribute to the user's safety, it evaluates the attention-required situation model as "invalid."

[0016] When the information collection system 10 receives an evaluation result from the mobility support device 30 that evaluates the caution-required situation model as "valid," it awards a reward to the person who pointed out the caution-required situation information on which the caution-required situation model was based (hereinafter sometimes referred to as the "person who pointed out the caution-required situation model").

[0017] In this way, the information collection system 10 according to the first embodiment can motivate the person who points out the problem to provide better information indicating a situation requiring attention by providing a reward according to the effectiveness evaluation result of the model of a situation requiring attention. In addition, by not paying a reward to a model of a situation requiring attention that is evaluated as "invalid," it is expected that the provision of low-quality information indicating a situation requiring attention can be suppressed.

[0018] Next, the information collection system 10, the caution-requiring situation indicating device 20, and the mobility support device 30 will be described in detail.

[0019] As shown in FIG. 1, the information collection system 10 includes an information collection unit 11, an attention-requiring situation model creation unit 12, an attention-requiring situation model storage unit 13, an information distribution unit 14, an evaluation result receiving unit 15, and a reward granting unit 16.

[0020] The information collecting unit 11 collects caution-requiring situation indication information including information on caution-requiring situations indicated by an indicater and an indicater ID from the caution-requiring situation indication device 20. The caution-requiring situation model creating unit 12 creates a caution-requiring situation model, which is a model of a caution-requiring situation, based on the collected caution-requiring situation indication information. The caution-requiring situation model storage unit 13 stores the caution-requiring situation model created by the caution-requiring situation model creating unit 12.

[0021] The information distribution unit 14 distributes the attention-requiring situation model stored in the attention-requiring situation model storage unit 13 to the mobility support device 30 in response to a request from the mobility support device 30. The evaluation result receiving unit 15 receives the effectiveness evaluation result of the attention-requiring situation model transmitted from the mobility support device 30. The reward granting unit 16 grants a reward to the person who pointed out the attention-requiring situation indication information on which the attention-requiring situation model evaluated as "effective" was based, based on the effectiveness evaluation result received by the evaluation result receiving unit 15.

[0022] Fig. 2 is a diagram showing the configuration of the attention-required situation indicating device 20. As shown in Fig. 2, the attention-required situation indicating device 20 is connected to a positioning device 201, a surroundings detection device 202, a driver monitoring device 203, and an operation device 204 provided in a person who indicates the situation 200. Some or all of these may be built into the attention-required situation indicating device 20.

[0023] The positioning device 201 measures the position of the pointer vehicle 200 based on a positioning signal from a Global Navigation Satellite System (GNSS). The positioning device 201 may correct the position of the pointer vehicle 200 measured from the positioning signal by a map matching process using output data from a vehicle speed sensor or an acceleration sensor of the pointer vehicle 200 and map data.

[0024] The periphery detection device 202 detects the surrounding conditions of the pointing out vehicle 200. The periphery detection device 202 can be configured, for example, with an image recognition device that recognizes images captured by a camera, a LiDAR (Light Detection And Ranging), a millimeter wave radar, or the like.

[0025] The driver monitoring device 203 monitors the state of the driver of the indicating vehicle 200. The driver monitoring device 203 has a camera for photographing the driver and a microphone for collecting the driver's voice, and can detect the driver's behavior, such as the direction of the driver's face, the direction of the driver's gaze, the voice, and the pointing action. The caution-required situation indicating device 20 can detect that the driver has indicated a caution-required situation from the driver's behavior detected by the driver monitoring device 203.

[0026] The driver monitoring device 203 may acquire the driver's state by a direct method or an indirect method. The direct method is a method of detecting physiological indicators such as the driver's face direction, line of sight, facial expression, foot position relative to the pedal, gripping pressure on the steering wheel, physical condition, heart rate, and respiratory rate. The indirect method is a method of estimating the driver's state from indicators indicating the driving state, such as the steering wheel direction, speed, and acceleration.

[0027] The operation device 204 is an input means for the driver of the indicating vehicle 200 to operate the attention-required situation indicating device 20. The operation device 204 may be any device, such as hardware such as a push button or an operating lever, software keys displayed on the screen of a display device, or a voice recognition device that recognizes voice operations.

[0028] As shown in FIG. 2, the caution-requiring situation indicating device 20 includes a caution-requiring situation indicating information generating unit 21, a pointing person ID storage unit 22, and a communication unit .

[0029] The pointer ID storage unit 22 is a storage medium that stores a pointer ID. The pointer ID may be any ID that can identify the pointer, such as an ID unique to the pointer vehicle 200, an ID unique to the caution-required situation indicating device 20, an ID given to the pointer by the information collection system 10, or an ID registered in the information collection system 10 by the pointer himself / herself. The pointer ID storage unit 22 may store a plurality of pointer IDs.

[0030] When the attention-required situation indication information generating unit 21 detects that the driver of the pointing out vehicle 200 has pointed out a situation requiring attention from the driver's behavior detected by the driver monitoring device 203, it generates attention-required situation indication information including information on the situation requiring attention and the ID of the driver who pointed out the situation requiring attention. The information on the situation requiring attention includes the point at which the situation requiring attention is pointed out and the contents of the situation requiring attention. The point at which the situation requiring attention is pointed out can be determined from the position of the pointing out vehicle 200 measured by the positioning device 201 when it is detected that the driver pointed out the situation requiring attention. In addition, the contents of the situation requiring attention can be determined from the surroundings of the pointing out vehicle 200 detected by the surroundings detection device 202 and the behavior of the driver detected by the driver monitoring device 203 around the time when it is detected that the driver pointed out the situation requiring attention.

[0031] The communication unit 23 judges whether or not the driver intends to provide the attention-required situation indication information to the information collection system 10 based on the driver's operation input to the operation device 204, and when it is judged that the driver intends to provide the information, transmits the attention-required situation indication information to the information collection system 10 using a communication device (not shown). The communication device may be built in the attention-required situation indication device 20, or may be a mobile phone, a smartphone, or the like externally attached to the attention-required situation indication device 20.

[0032] Fig. 3 is a diagram showing the configuration of the mobility support device 30. As shown in Fig. 3, the mobility support device 30 is connected to a positioning device 301, a surroundings detection device 302, an operation device 304, and a notification device 305 provided in a client vehicle 300. Some or all of these may be built into the mobility support device 30.

[0033] The positioning device 301, the surroundings detection device 302, and the operation device 304 have the same functions as the positioning device 201, the surroundings detection device 202, and the operation device 204 shown in FIG. 2, respectively.

[0034] The notification device 305 is a device that notifies the driver of the client vehicle 300. The notification device 305 may be any device capable of notifying the driver, such as a voice output device, an image display device, an illumination device, or a vibration device. The notification device 305 is used to notify a situation requiring attention. The image display device includes a HUD (Head-Up Display) that can display a virtual image that appears to exist in front of the vehicle by projecting an image on the windshield (windshield) of the vehicle. When a HUD that displays a virtual image that appears to exist in front of the vehicle or an illumination device that illuminates light toward the outside of the vehicle is used as the notification device 305, the notification device 305 can notify the driver of the situation requiring attention and can also perform line-of-sight guidance that guides the driver's line of sight toward a target requiring attention.

[0035] As shown in FIG. 3, the travel assistance device 30 includes a communication unit 31, a caution-requiring situation model storage unit 32, a notification determination unit 33, and a validity determination unit .

[0036] The communication unit 31 uses a communication device (not shown) to request the information collection system 10 to distribute a model of a situation requiring attention, and receives a model of a situation requiring attention distributed from the information collection system 10.

[0037] The caution-required situation model storage unit 32 stores the caution-required situation model received by the communication unit 31 .

[0038] The notification determination unit 33 determines whether or not to notify the driver of the client vehicle 300 of a caution-required situation. Specifically, the notification determination unit 33 determines whether or not the situation around the client vehicle 300 is close to the caution-required situation model based on the position of the client vehicle 300 measured by the positioning device 301 and the situation around the client vehicle 300 detected by the periphery detection device 302, and when the situation around the client vehicle 300 becomes close to the caution-required situation model, determines that the client vehicle 300 will encounter a caution-required situation, and notifies the driver of the client vehicle 300 of the caution-required situation using the notification device 305.

[0039] The validity determination unit 34 evaluates the validity of the alert of the alert situation performed by the alert determination unit 33, and thereby evaluates the validity of the alert-required situation model corresponding to the alert. Specifically, the validity determination unit 34 determines whether the alert contributed to the user's safety, and when it is determined that the alert contributed to the user's safety, it determines that the alert was effective, and evaluates the alert-required situation model corresponding to the alert as "valid". In addition, the validity determination unit 34 transmits the effectiveness evaluation result of the alert-required situation model to the information collection system 10 via the communication unit 31.

[0040] The validity determination unit 34 may transmit both the evaluation result indicating "valid" and the evaluation result indicating "invalid" to the information collection system 10, or may transmit only the evaluation result indicating "valid" to the information collection system 10. For example, if a caution-requiring situation does not occur when the client vehicle 300 passes through a caution-requiring target point indicated by the caution-requiring situation model, or if it is determined that the driver is paying sufficient attention even if a caution-requiring situation occurs, the validity determination unit 34 may automatically transmit an evaluation result in which the caution-requiring situation model is evaluated as "invalid" to the information collection system 10.

[0041] 4 is a flowchart showing the operation of the attention-requiring situation indicating device 20. Hereinafter, the operation of the attention-requiring situation indicating device 20 will be described with reference to the flowchart in FIG.

[0042] The attention-required situation indicating device 20 is activated in response to a specific activation operation. For example, the attention-required situation indicating device 20 may be activated in conjunction with the pointing out vehicle 200 starting to travel.

[0043] When the caution-required situation indicating device 20 is started, the caution-required situation indication information generating unit 21 acquires information on the position of the pointer's vehicle 200 measured by the positioning device 201 (step S200). The information on the position of the pointer's vehicle 200 may include information on the orientation of the pointer's vehicle 200. The orientation of the pointer's vehicle 200 can be calculated from the position history of the pointer's vehicle 200. In addition, the orientation of the pointer's vehicle 200 may be corrected based on the steering angle or acceleration of the pointer's vehicle 200.

[0044] The attention-required situation indication information generating unit 21 also acquires information on the surrounding situation of the indicating vehicle 200 detected by the surrounding detection device 202 (step S201). The information on the surrounding situation acquired by the attention-required situation indication information generating unit 21 may be any information, such as the positions of nearby moving objects, road shapes, road surface conditions, images of the surroundings, and surrounding sounds.

[0045] Furthermore, the attention-required situation indication information generating unit 21 acquires information on the state of the driver of the indicating vehicle 200 detected by the driver monitoring device 203 (step S202). The state of the driver acquired by the attention-required situation indication information generating unit 21 may be any information that can indicate the behavior of the driver, such as the driver's line of sight, voice, or pointing action.

[0046] The caution-required situation indication information generating unit 21 judges whether or not the driver has indicated a caution-required situation based on the information on the driver's state (step S203).

[0047] Here, an example of a situation requiring caution will be shown. For example, as shown in Fig. 5, when there is a junction with a side road on the left ahead of the pointer's vehicle 200 and a bicycle jumps out from the side road, the driver of the pointer's vehicle 200 points out this situation as a situation requiring caution.

[0048] 5, the driver may, for example, say "A bicycle jumps out from the side road on the left," say "A bicycle jumps out" after moving his / her gaze to the side road on the left, point to the side road on the left and say "A bicycle jumps out," or make a specific gesture such as wagging his / her finger after moving his / her gaze to the side road on the left. The caution-required situation indication information generating unit 21 detects that a caution-required situation has been indicated by detecting such driver behavior.

[0049] The point where the caution situation is indicated may be the position of the person who pointed out the situation measured by the positioning device 201 when the driver pointed out the caution situation, or may be the position of the caution point detected by the surroundings detection device 202 (the merging point with a side road in the example of FIG. 5). Basically, the positions of the two are close to each other, so for the sake of simplicity of explanation, the position of the person who pointed out the situation measured by the positioning device 201 when the driver pointed out the caution situation is considered to be the position of the caution point. In other words, in the example of FIG. 5, the position of the person who pointed out the situation measured by the positioning device 201 when the driver pointed out the caution situation and the position of the merging point with a side road are both considered to be position P1.

[0050] The contents of the situation requiring attention are extracted from the surroundings of the person reporting the problem 200 detected by the surroundings detection device 202 and the driver's behavior detected by the driver monitoring device 203. The contents of the situation requiring attention include information on the object requiring attention and the thing requiring caution. The object requiring attention may be a moving object or a specific location. In the example of FIG. 5, the contents of the situation requiring attention is "a bicycle jumping out from the side road on the left", the object requiring attention is "a bicycle" or "a junction with a side road", and the thing requiring caution is "a bicycle jumping out".

[0051] 6, a case will be described in which the driver of the pointing out vehicle 200 points out a situation requiring caution when the road on which the pointing out vehicle 200 is traveling narrows and the bicycle ahead moves to the right and may collide with the pointing out vehicle 200. The same applies when a bicycle traveling on the sidewalk on the side of the road runs out onto the roadway at the point where the sidewalk ends.

[0052] In this case, when the watchful-state situation indication information generating unit 21 detects that the driver has uttered, for example, "The bicycle is moving to the right," it determines that a watchful-state situation has been indicated, and determines that the content of the watchful-state situation is "The bicycle is running off the road." In addition, the point where the watchful-state situation is indicated is position P2, the point where the road width narrows.

[0053] Here, an example has been shown in which the caution-required situation indication information generating unit 21 automatically detects that the driver has indicated a caution-required situation, but as will be described later, it may also be determined that the driver has indicated a caution-required situation by operating the operating device 204.

[0054] Returning to Fig. 4, when the caution-required situation indication information generating unit 21 determines that the driver has indicated a caution-required situation (YES in step S203), it creates caution-required situation indication information (step S204). The caution-required situation indication information may be configured in various forms, but in this embodiment, the caution-required situation indication information is configured from the ID of the person who indicated it, the point where the caution-required situation was indicated, and the details of the caution-required situation, as shown in Fig. 7. Note that the caution-required situation indication information shown in Fig. 7 corresponds to the examples of caution-required situations shown in Figs. 5 and 6.

[0055] When the attention-required situation indication information is created, the communication unit 23 judges whether or not the driver intends to provide the attention-required situation indication information to the information collection system 10 based on the driver's operation input to the operation device 204 (step S205). For example, when a specific operation is input to the operation device 204, it is judged that the driver intends to provide the attention-required situation indication information. Alternatively, it may be judged that the driver intends to provide the attention-required situation indication information by the driver indicating a attention-required situation. That is, step S205 may be omitted.

[0056] When the communication unit 23 determines that the driver has an intention to provide the caution-required situation indication information (YES in step S206), the communication unit 23 transmits the caution-required situation indication information to the information collection system 10 (step S207).

[0057] Thereafter, the attention-required situation indicating device 20 checks whether the traveling of the person who pointed out the situation 200 has ended (step S208). If the traveling is still continuing (NO in step S208), the process returns to step S200, and if the traveling has ended (YES in step S208), the attention-required situation indicating device 20 ends the operation. Note that if it is determined that the driver has not pointed out a situation that requires attention (NO in step S203) and if it is determined that the driver has an intention to provide attention-required situation indication information (NO in step S206), the attention-required situation indication information is not created or transmitted, and the process proceeds to step S208, where it is checked whether the traveling of the person who pointed out the situation 200 has ended.

[0058] 4, each time attention-required situation indication information is created in step S204, a determination is made in step S205 as to whether or not the driver intends to provide the attention-required situation indication information. However, the attention-required situation indication information may be stored without confirming the driver's intention at the time the attention-required situation indication information is created, and the driver may collectively select, for example, when the pointer vehicle 200 is stopped, one or more pieces of attention-required situation indication information stored up to that point to be transmitted to the information collection system 10.

[0059] Next, the operation of the information collecting system 10 will be described. In this embodiment, as an example of the operation of the information collecting system 10, a multi-process configuration in which three processes corresponding to the flowcharts shown in Figures 8, 9, and 10, that is, an information collecting process, an information distribution process, and a reward granting process, are executed in parallel will be described. The program configuration of the information collecting system 10 may be a single-process configuration, or a multi-process configuration in which four or more processes are executed in parallel.

[0060] FIG. 8 is an operational flow of the information collection process of the information collection system 10.

[0061] In the information collection process, the information collection unit 11 receives the attention-requiring situation indication information transmitted from the attention-requiring situation indication device 20 (step S100). When the attention-requiring situation indication information is received, the attention-requiring situation model creation unit 12 creates an attention-requiring situation model based on the attention-requiring situation indication information (step S101). The created attention-requiring situation model is stored in the attention-requiring situation model storage unit 13.

[0062] In this embodiment, for the sake of simplicity, the attention-required situation model creation unit 12 creates the attention-required situation model from the received attention-required situation indication information in its original data structure. That is, the attention-required situation model is also composed of the ID of the person who indicates the attention-required situation, the point where the attention-required situation is indicated, and the contents of the attention-required situation, as in FIG. 7.

[0063] In addition, if multiple models of situation requiring attention with overlapping content but different pointer IDs are obtained, only the model of situation requiring attention that was pointed out the oldest may be adopted, or the multiple models of situation requiring attention with overlapping content may be merged into one to create a model of situation requiring attention with multiple pointer IDs.

[0064] The attention-requiring situation model storage unit 13 may categorize and store the attention-requiring situation models based on the point where the attention-requiring situation is pointed out, the content of the attention-requiring situation, the ID of the person who pointed out the situation, geographical features, etc. Also, the attention-requiring situation model storage unit 13 may store the attention-requiring situation models by using a relational database management system (RDBMS).

[0065] FIG. 9 is an operational flow of the information distribution process of the information collection system 10.

[0066] In the information distribution process, the information distribution unit 14 receives a distribution request for an attention-requiring situation model transmitted from the mobility support device 30 (step S110). Upon receiving the distribution request for the attention-requiring situation model, the information distribution unit 14 reads out the attention-requiring situation model corresponding to the distribution request from the attention-requiring situation model storage unit 13, and distributes it to the mobility support device 30 that sent the distribution request (step S111).

[0067] The delivery request for the caution situation model may include information on the range of the caution situation model for which delivery is requested (hereinafter referred to as the "requested delivery range"). The requested delivery range for the caution situation model is, for example, a caution situation model in which the indicated point of the caution situation is within a specific range. The specific range here is, for example, a certain range (e.g., a range of 100 km square) centered on the position of the mobility support device 30, a specific range unrelated to the position of the mobility support device 30, a range along the planned driving route of the mobility support device 30, a range along the past driving routes of the mobility support device 30, etc.

[0068] FIG. 10 is an operational flow of the reward granting process of the information collection system 10.

[0069] In the reward granting process, the evaluation result receiving unit 15 receives the effectiveness evaluation result of the caution-requiring situation model transmitted from the mobility support device 30 (step S120). When the effectiveness evaluation result of the caution-requiring situation model is received, the reward granting unit 16 checks the content of the effectiveness evaluation result (i.e., whether the evaluation result is "valid" or "invalid"), and grants a reward to the person who pointed out the caution-requiring situation model that was evaluated as "valid" (step S121).

[0070] The reward may be anything, such as money, electronic money, a coupon, an increase in the rating of the person who pointed out the problem, some kind of points, or the right to advertise the mobility support device 30. The amount of reward may be calculated according to the number of “valid” evaluation results obtained for each person who pointed out the problem or for each caution-requiring situation model.

[0071] Next, the operation of the mobility support device 30 will be described. In this embodiment, as an example of the operation of the mobility support device 30, a multi-process configuration in which two processes corresponding to the flowcharts shown in Figures 11 and 12, that is, an information distribution request process and an evaluation result transmission process, are executed in parallel will be described. The program configuration of the information collection system 10 may be a single-process configuration, or a multi-process configuration in which three or more processes are executed in parallel.

[0072] FIG. 11 is a flow chart showing an operation of the information distribution request process of the travel support device 30. As shown in FIG.

[0073] In the information distribution request process, first, the communication unit 31 judges whether or not it is time to request distribution of a caution-required situation model from the information collection system 10 (step S300). If it is time to request distribution of a caution-required situation model (YES in step S300), the communication unit 31 transmits a request to distribute the caution-required situation model to the information collection system 10 (step S301).

[0074] The timing for requesting delivery of the caution situation model may be any timing, such as when the client vehicle 300 starts driving, when a route that passes through a place that has not been driven before is set as the planned driving route for the client vehicle 300, or when the client vehicle 300 enters a place that has not been driven before.

[0075] Thereafter, the model of the caution-requiring situation is distributed from the information collection system 10 that has received the distribution request, and the communication unit 31 receives the model of the caution-requiring situation (step S302). The received model of the caution-requiring situation is stored in the model of the caution-requiring situation storage unit 32 (step S303).

[0076] Thereafter, the mobility support device 30 checks whether the client vehicle 300 has finished traveling (step S304). If the traveling is still continuing (NO in step S304), the process returns to step S300, and if the traveling has finished (YES in step S304), the mobility support device 30 ends the operation. If it is not the timing to request the distribution of the caution-requiring situation model (NO in step S300), the process proceeds to step S304 without transmitting the request to distribute the caution-requiring situation model, and it is checked whether the client vehicle 300 has finished traveling.

[0077] FIG. 12 shows an operational flow of the caution-requiring situation notification process.

[0078] In the caution situation notification process, the notification determination unit 33 acquires information on the position of the client vehicle 300 measured by the positioning device 301 (step S310). The information on the position of the client vehicle 300 may include information on the orientation of the client vehicle 300. The orientation of the client vehicle 300 can be calculated from the position history of the client vehicle 300. In addition, the orientation of the client vehicle 300 may be corrected based on the steering angle or acceleration of the client vehicle 300.

[0079] The notification determination unit 33 also acquires information on the surrounding conditions of the client vehicle 300 detected by the surrounding detection device 302 (step S311). The information on the surrounding conditions acquired by the notification determination unit 33 may be any information, such as the positions of nearby moving objects, road shapes, road surface conditions, images of the surroundings, and surrounding sounds.

[0080] Next, the notification judgment unit 33 judges whether the situation around the client vehicle 300 is close to any of the caution situation models stored in the caution situation model memory unit 32 based on information on the position of the client vehicle 300 and the surrounding conditions, thereby determining whether the client vehicle 300 is in a caution situation (step S312).

[0081] 7 is stored in the caution-required situation model storage unit 32, when the position of the client vehicle 300 approaches the position P1 or P2 of the indicated point of the caution-required situation (for example, when the distance to the indicated point position P1 or P2 becomes 10 m or less), it is determined that the situation around the client vehicle 300 has become close to the caution-required situation model. At this time, the traveling direction of the client vehicle 300 and whether or not a bicycle has been detected by the periphery detection device 302 may be taken into consideration.

[0082] When it is determined that the client vehicle 300 is in a caution-requiring situation (YES in step S313), the notification determination unit 33 uses the notification device 305 to notify the driver of the client vehicle 300 of the caution-requiring situation (step S314). The content of this notification is determined according to the content of the caution-requiring situation in the caution-requiring situation model. For example, if a caution-requiring situation model like that shown in FIG. 7 is stored in the caution-requiring situation model storage unit 32, and when the position of the client vehicle 300 approaches position P1, which is the indicated point of the caution-requiring situation, a voice message such as "Watch out for bicycles jumping out" may be output from the notification device 305.

[0083] Furthermore, in the case where the notification device 305 includes a HUD, the notification determination unit 33 may display a display object 35, which is a virtual image indicating the position of a caution target, on the windshield of the client vehicle 300, as shown in Fig. 13. Fig. 13 shows a caution situation in which a pedestrian may jump out from between multiple parked vehicles on the roadside (corresponding to the caution situation of "Info 7" in Fig. 14 shown later), and the display object 35 visually notifies the positions of multiple parked vehicles that are caution targets in the caution situation.

[0084] Next, the validity determination unit 34 judges the validity of the alert of the caution situation performed in step S314, thereby evaluating the validity of the caution situation model corresponding to the alert (step S315). In this embodiment, if the alert is valid, the driver of the client vehicle 300 inputs a specific operation indicating that to the operation device 304, and the validity determination unit 34 judges that the alert is valid if the specific operation is input within a certain time (for example, within 10 seconds) after the alert is performed.

[0085] If the validity determination unit 34 determines that the notification was valid (YES in step S316), it evaluates the caution situation model corresponding to the notification as “valid” and transmits the evaluation result to the information collection system 10 via the communication unit 31 (step S317).

[0086] Thereafter, the mobility support device 30 checks whether the client vehicle 300 has finished traveling (step S318). If the traveling continues (NO in step S318), the process returns to step S310, and if the traveling has finished (YES in step S318), the mobility support device 30 ends the operation. If it is not determined that the client vehicle 300 is in a caution-requiring situation (NO in step S313), no notification is made and the process proceeds to step S318. If it is determined that the notification was not effective (NO in step S316), the process proceeds to step S318 without transmitting the validity evaluation result. Alternatively, if it is determined that the notification was not effective (NO in step S316), the validity determination unit 34 may transmit the evaluation result of "invalid" to the information collection system 10 and then proceed to step S318.

[0087] [Variation 1] In the travel support device 30 of the first embodiment, the validity determination unit 34 determines whether the notification was valid based on the operation input to the operation device 304, but the validity determination unit 34 may determine whether the notification was valid based on the voice or gesture of the driver of the client vehicle 300. For example, the notification may be determined to be valid when the driver of the travel support device 30 utters a phrase such as "I'm saved" or makes a specific gesture.

[0088] Furthermore, the effectiveness evaluation result does not have to be a two-level scale of "effective" or "ineffective," but may be a multi-level scale of three or more levels, including, for example, "highly effective," "average," and "opposite effect."

[0089] [Variation 2] The data structure of the caution situation indication information and the caution situation model is not limited to the simple one shown in Figure 7, and may include, for example, the position and attributes of a caution object in a caution situation, as well as caution attributes for the caution object, as shown in Figure 14.

[0090] The attention-requiring object may include a traffic violation control site. Generally, a traffic violation control site is a place where a traffic violation is likely to be committed by mistake, and therefore, the driving assistance is highly effective.

[0091] When the information of the caution-required situation model includes attributes of the caution-required object, the manner of notification performed by the travel assistance device 30 can be changed according to the attributes of the caution-required object. For example, when the caution-required situation is notified by the HUD, a mark according to the attributes can be superimposed on the direction of the caution-required object. The attributes of the caution-required object may also be notified by voice. This allows the driver of the client vehicle 300 to narrow down the objects to be careful of.

[0092] The attributes of the caution items indicate what to be careful of. For example, if the object to be careful of is a bicycle, the attributes include jumping out into the road, wobbling, and sudden lane changes. Other attributes may include caution against being hit when changing lane of the client vehicle 300, caution against contact with pedestrians when turning right or left, and caution against violating legal compliance obligations (such as stopping, direction of travel restrictions, and speeding). By being notified of the attributes of the caution items, the driver of the client vehicle 300 can narrow down the contents to which he or she should be careful.

[0093] The contents of the situation requiring caution may include the driving environment of the vehicle, because there are situations requiring caution that occur only in bad weather or during traffic congestion, such as flooding of roads during rainfall, crosswinds at the exit of a tunnel during strong winds, and pedestrians jumping out between vehicles during traffic congestion.

[0094] The position of the caution target is not limited to an absolute position (latitude, longitude), but may be a relative position with respect to the vehicle (the pointing out vehicle 200 or the pointing out vehicle 200). This is because there are caution situations that occur in unspecified locations, such as caution situations caused by overtaking, passing, turning right or left, changing lanes, and caution situations caused by vehicles parked on the roadside, vehicles involved in accidents, emergency vehicles, suspicious vehicles, poorly maintained vehicles, and the like.

[0095] More specifically, situations requiring caution that may occur in unspecified locations include situations where a bicycle or pedestrian may suddenly jump out between parked vehicles, situations where an obstacle (including pedestrians) may be caught up in the difference in turning radius when turning right at a narrow intersection, and situations where the driver of a motorcycle or bicycle in front may turn his head from side to side (to check both sides) and change course or lane.

[0096] [Variation 3] In the first embodiment, an example is shown in which the moving body is a vehicle, but the mobility support system according to the present disclosure may be applied to mobility support systems for ships, aircraft, helicopters, etc. For example, in the case of a ship, a model of a situation requiring caution is created from information indicating a situation requiring caution provided by an experienced operator according to a specific location, region, and environment, such as ocean currents, islands, reefs, wind and rain, thereby preventing shipwrecks. In particular, a model of a situation requiring caution that combines information on the location of reefs and other locations with information on ocean currents is highly effective in preventing strandings.

[0097] [Variation 4] The travel support system according to the present disclosure may be applied to a travel support system for pedestrians, bicycles, and other light vehicles. In this case, the attention-requiring situation indicating device 20 and the travel support device 30 may be realized by an application that runs on a mobile communication terminal (e.g., a mobile phone or a smartphone) with a positioning function. In addition, a dedicated terminal for light vehicles may be provided for the light vehicles.

[0098] [Variation 5] The mobility support system according to the present disclosure may be applied to mobility support systems for trucks, buses, and special vehicles. This is because there are situations that require special attention that are unique to trucks, buses, and special vehicles. In addition, the value of imparting the know-how of veteran drivers regarding situations that require special attention to novice drivers through the mobility support system is greater than that of passenger cars. Trucks and buses are wide, and there are situations that require special attention that are different from passenger cars, such as whether they can pass on narrow roads, caution against getting caught, and ease of slipping. Dump trucks also have special situations that require special attention, such as when transporting soil and sand or when driving around a house.

[0099] For buses and other vehicles, the prevention of passengers falling over due to sudden braking or sudden steering is also an additional situation requiring caution. Emergency vehicles such as police cars, ambulances, and fire engines also need to check for special situations when driving in an emergency, such as whether other vehicles are stopped or have made way for the emergency vehicle, so the situations requiring caution differ from those for general vehicles. Forklifts also have special situations requiring caution due to their rear-wheel steering, as well as situations that are unique to factories where forklifts are moved.

[0100] In addition, when it comes to operating electric trains, steam locomotives, and trams, there are special situations that require caution when approaching a platform or a railroad crossing, and so it is important for experienced drivers to impart their know-how.

[0101] [Variation 6] In addition, the reporter vehicle 200 and the client vehicle 300 may be categorized according to the purpose of use of the vehicle, and the attention-required situation indication information may be collected and the attention-required situation model may be created. That is, the attention-required situation indication information and the attention-required situation model may include information on the type of purpose of use of the reporter vehicle 200 or the client vehicle 300. The purpose of use of the vehicle may be delivery, moving, pick-up and drop-off, transporting luggage, transporting animals, etc.

[0102] [Variation 7] In the first embodiment, no provisions were made regarding the caution situation and the reward amount, but for each type of caution situation model, the amount of loss when the caution situation leads to an accident (conversely, the amount of loss that can be avoided if the accident can be avoided) can be estimated, and the reward amount for each type of caution situation model can be set according to that amount.

[0103] [Variation 8] The mobility support device 30 and the caution-requiring situation indicating device 20 may be integrated together. In that case, the indicating person's vehicle 200 and the client's vehicle 300 are the same vehicle.

[0104] [Variation 9] When the sender of the validity evaluation result meets certain conditions, the reward granting unit 16 of the information collection system 10 may invalidate the validity evaluation result so as not to grant a reward to the person who pointed out the validity evaluation result.

[0105] For example, if the client who sent the validity evaluation result matches the person who pointed out the model of the caution situation that corresponds to the validity evaluation result, the validity evaluation result may be invalidated. This is because if the client and the person who pointed out the validity evaluation result are the same, it is highly likely that the validity evaluation result was staged in order to illegally receive rewards.

[0106] In addition, if the same client sends a "valid" evaluation result for the same model of suspicious situations within a certain period of time, the validity evaluation result may be invalidated. Even if the client and the person who pointed it out are different, if the same client repeatedly sends a "valid" evaluation result, it is highly likely that it is an organized act of self-inflict (aiding and abetting the illegal receipt of rewards).

[0107] [Variation 10] When the travel support device 30 monitors the driving operation of the driver of the client vehicle 300 and notifies the driver of a situation requiring attention, if the driver performs a driving operation according to the contents of the notification, that is, a driving operation to avoid the notified situation requiring attention, a reward may be given to the driver (client). This has the effect of contributing to safe driving by the client.

[0108] [Variation 11] In the attention-required situation notification process (FIG. 12) of the travel support device 30 shown in the first embodiment, the attention-required situation is notified regardless of whether the driver of the client vehicle 300 is aware of the attention-required situation, but the travel support device 30 may notify the attention-required situation only when the driver is not aware of the attention-required situation. Also, when the travel support device 30 detects that the driver of the client vehicle 300 has changed from a state in which he / she is unaware of the attention-required situation to a state in which he / she has noticed the attention-required situation, triggered by the notification, the travel support device 30 may consider that the notification has contributed to the safety of the user and may determine that the notification was effective.

[0109] Fig. 15 is a block diagram of a travel support device 30 according to this modification. The configuration of the travel support device 30 in Fig. 15 is obtained by adding a driver monitoring device 303 to the configuration in Fig. 3. The driver monitoring device 303 has the same functions as the driver monitoring device 303 shown in Fig. 2.

[0110] 16 is an operational flow of a caution-requiring situation notification process of the travel support device 30 according to this modification. The flow in FIG. 16 is obtained by adding steps S320, S321, and S322 to the flow in FIG.

[0111] Step S320 is performed when it is determined in step S313 that the client vehicle 300 is in a caution-requiring situation (YES in step S313). In step S320, the notification determination unit 33 acquires information on the driver's state from the driver monitoring device 303.

[0112] Step S321 is performed following step S320. In step S321, the notification determination unit 33 determines whether the driver is aware of the caution-requiring situation based on the driver's condition acquired in step S320. If the driver is not aware of the caution-requiring situation (NO in step S321), the process proceeds to step S314, where the driver is notified of the caution-requiring situation. If the driver is aware of the caution-requiring situation (YES in step S321), the driver is not notified of the caution-requiring situation, and the process proceeds to step S318.

[0113] Whether the driver is aware of the situation requiring attention can be determined, for example, by the following methods. For example, there is a method of determining from the driver's line of sight and the direction of the face. When this method is used, the notification determination unit 33 determines that the driver is aware of the situation requiring attention when the direction of the driver's face and line of sight match the direction of the object requiring attention.

[0114] Alternatively, a method of determining based on the physiological or psychological state of the driver may be used. When using this method, the notification determination unit 33 determines that the driver is aware of a situation requiring caution when there is a change in the driver's heart rate or breathing, when the driver's facial expression becomes serious, when the driver's grip on the steering wheel increases, or when other such changes occur.

[0115] Alternatively, a method of indirectly determining from the output of a vehicle sensor of the client vehicle 300 may be used. When using this method, the notification determination unit 33 determines that the driver is aware of a situation requiring attention when detecting a steering operation to avoid a target requiring attention or a braking or accelerating operation to avoid a collision.

[0116] A plurality of the above-mentioned determination methods may be combined, and a comprehensive determination as to whether or not the driver is aware of the situation requiring attention may be made based on the results of the plurality of determinations.

[0117] Step S322 is performed after step S314, that is, after the notification of the caution-requiring situation is performed. In step S322, the notification determination unit 33 acquires information on the driver's state from the driver monitoring device 303, similar to step S320.

[0118] After step S322, the process proceeds to step S315, where the validity determination unit 34 determines the validity of the notification of the caution-required situation performed in step S314, thereby evaluating the validity of the caution-required situation model corresponding to the notification. However, in this embodiment, the validity determination unit 34 compares the driver's state acquired in step S320 before the notification with the driver's state acquired in step S321 after the notification, and determines the validity of the notification from the change in the driver's state before and after the notification.

[0119] For example, the validity determination unit 34 may determine that the notification contributed to the safety of the driver and determine that the notification was effective when it is detected that the state of the driver has changed from a state where the driver is unaware of the attention-requiring situation to a state where the driver has noticed the situation, triggered by the notification. The validity determination unit 34 may also detect the direction of the driver's face or the direction of the driver's gaze, and determine that the notification contributed to the safety of the driver and determine that the notification was effective when it is detected that the direction of the driver's face or the direction of the driver's gaze has changed from a state where the driver is not facing the attention-requiring object to a state where the driver is facing the attention-requiring object, triggered by the notification. The validity determination unit 34 may also detect the driver's behavior, and determine that the notification contributed to the safety of the driver and determine that the notification was effective when it is detected that the driver has taken a behavior to avoid the attention-requiring object, triggered by the notification.

[0120] According to this modification, when the driver of the client vehicle 300 is not aware of the situation requiring attention, the situation requiring attention is notified, and the effectiveness of the notification is automatically determined depending on whether the driver has noticed the situation requiring attention, so that the effectiveness of the notification is objectively evaluated without being subjectively determined by the driver. Also, the driver does not have to take the trouble of determining the effectiveness of the notification, which improves convenience for the driver.

[0121] In this modification, the method of determining the validity of the notification based on the operation of the operation device 304 described in the first embodiment may be used in combination.

[0122] <Embodiment 2> In the mobility support system of the first embodiment, when a caution-requiring situation is pointed out by the driver of the pointing out vehicle 200, data including information on the caution-requiring situation recorded by the positioning device 201, the periphery detection device 202, and the driver monitoring device 203 is analyzed by the caution-requiring situation indicating device 20, and the analysis result is transmitted to the information collection system 10 as caution-requiring situation indication information. In the second embodiment, an example is shown in which the data recorded by the positioning device 201, the periphery detection device 202, and the driver monitoring device 203 when a caution-requiring situation is pointed out is analyzed by the information collection system 10. Hereinafter, data before analysis, i.e., data obtained as it is from the positioning device 201, the periphery detection device 202, the driver monitoring device 203, etc., is referred to as "raw data".

[0123] Fig. 17 is a diagram showing a configuration of a travel assistance system according to embodiment 2. The configuration of the travel assistance system in Fig. 17 differs from the configuration in Fig. 1 in that the attention-required situation model creation unit 12 of the attention-required situation indication device 20 includes a raw data storage unit 12a and a raw data analysis unit 12b.

[0124] Furthermore, in the second embodiment, the caution requiring situation indicating device 20 does not analyze the raw data acquired from the positioning device 201, the periphery detection device 202, and the driver monitoring device 203, and the caution requiring situation indicating information transmitted by the caution requiring situation indicating device 20 includes, as information on the caution requiring situation, raw data recorded by the positioning device 201, the periphery detection device 202, and the driver monitoring device 203 during a certain period before and after the time when the driver indicated the caution requiring situation. Hereinafter, this raw data is referred to as "raw data of the caution requiring situation".

[0125] The raw data recorded by the positioning device 201 is position data of the pointer vehicle 200. The raw data recorded by the periphery detection device 202 is video data around the pointer vehicle 200 recorded by a camera, audio data around the pointer vehicle 200 recorded by a sound collector, output data of the periphery sensor, etc. Furthermore, the raw data recorded by the driver monitoring device 203 is video data of the driver recorded by a camera, audio data of the driver's voice recorded by a sound collector, etc. The caution-required situation indication information transmitted from the caution-required situation indication device 20 includes one or more of these raw data.

[0126] The raw data storage unit 12a temporarily stores raw data (raw data of a caution situation) included in the caution situation indication information received from the caution situation indication device 20. The raw data analysis unit 12b analyzes the raw data of the caution situation stored in the raw data storage unit 12a, and generates a caution situation model based on the analysis result. In addition, if the raw data analysis unit 12b has a learning function, it may reanalyze the raw data corresponding to the caution situation model already stored in the caution situation model storage unit 13 according to the progress of learning, and the caution situation model creation unit 12 may update the caution situation model based on the analysis result.

[0127] 18 is a flowchart showing the operation of the caution-requiring situation indicating device 20 according to embodiment 2. The flow in FIG. 18 is obtained by adding step S210 to the flow in FIG.

[0128] Step S210 is performed when it is determined in step S203 that the driver has pointed out a situation requiring attention (YES in step S203). In step S210, the same information acquisition as in steps S201 to S103, that is, information on the position of the pointer vehicle 200, information on the surrounding conditions of the pointer vehicle 200, and information on the state of the driver of the pointer vehicle 200, is continued for a certain period of time.

[0129] After step S210, the process proceeds to step S204, where attention-required situation indication information is created (step S204). At this time, the attention-required situation indication information generation unit 21 includes, as information on the attention-required situation, raw data recorded by the periphery detection device 202 and the driver monitoring device 203 during a certain period before and after the time when the driver indicated the attention-required situation (i.e., raw data of the attention-required situation), in the attention-required situation indication information. The attention-required situation indication information generation unit 21 does not need to analyze the raw data of the attention-required situation.

[0130] By performing step S210 after step S203, the caution-required situation indication information generation unit 21 can include in the caution-required situation indication information not only the raw data before the time when the driver indicated the caution-required situation, but also the raw data recorded for a certain period of time after that time.

[0131] The information collection system 10 of the second embodiment executes four processes in parallel: the information collection process, information distribution process, and reward granting process described in the first embodiment, plus a data analysis process described below.

[0132] However, in the second embodiment, in the flow of the information collection process (Figure 8), the caution-required situation indication information including the raw data of the caution-required situation received in step S100 is stored in the raw data storage unit 12a of the caution-required situation model creation unit 12, and in step S101, a caution-required situation model is created based on the content of the caution-required situation determined by the raw data analysis unit 12b by analyzing the raw data stored in the raw data storage unit 12a.

[0133] FIG. 19 is an operational flow of the data analysis process of the information collection system 10.

[0134] In the data analysis process, first, the raw data analysis unit 12b judges whether it is time to analyze the raw data (step S120). The analysis may be performed at regular intervals (for example, once a week), or at any timing, such as when an instruction is given by the operator of the information collection system 10, or when attention-requiring situation indication information is received from the attention-requiring situation indication device 20.

[0135] If it is time for analysis (YES in step S120), the raw data analysis unit 12b reads out raw data of the caution-requiring situation from the raw data storage unit 12a (step S121). Then, the raw data analysis unit 12b analyzes the raw data using a predetermined analysis method to determine the content of the caution-requiring situation (step S122). In step S101 of the information collection process flow (FIG. 8), a caution-requiring situation model such as that shown in FIG. 7 or FIG. 14 is created based on the content of the caution-requiring situation determined in step S122.

[0136] The raw data may be analyzed using machine learning processing such as a Convolutional Neural Network (CNN). Machine learning may be unsupervised learning, or may be supervised learning, such as learning the relationship between the video data and the content of the caution situation using the content of the caution situation determined from the audio data as a teacher.

[0137] Generally, the CPU processing power of the server 100 is higher than that of the terminal device that serves as the caution requiring situation indication device 20. Therefore, by performing analysis and learning processing of raw data on caution requiring situations in the server 100 as in this embodiment, more advanced processing can be achieved than by performing these processes in the caution requiring situation indication device 20.

[0138] The operation of the movement support device 30 is similar to that of the first embodiment.

[0139] [Variation 1] The information collection system 10 may distribute the analysis rules used by the raw data analysis unit 12b to analyze the raw data of the caution-requiring situation, or the analysis engine obtained by machine learning, to the caution-requiring situation indication device 20. In other words, the caution-requiring situation model creation unit 12 may download the analysis rules or analysis engine used by the raw data analysis unit 12b from the information collection system 10, so that the caution-requiring situation indication device 20 can analyze the raw data using the analysis rules or analysis engine.

[0140] In this case, the caution-requiring situation indicating device 20 may have two operation modes: a raw data transmission mode in which caution-requiring situation indicating information including raw data is transmitted as in embodiment 2, and an analysis result transmission mode in which caution-requiring situation indicating information including the contents of the caution-requiring situation that is the analysis result of the raw data is transmitted as in embodiment 1. Since the amount of data of the analysis result is smaller than the raw data itself, the analysis result transmission mode can contribute to reducing communication resources.

[0141] Furthermore, the information collection system 10 may perform a learning process in an environment that simulates the hardware resources of the caution-requiring situation indicating device 20 and distribute the learning logic to the caution-requiring situation indicating device 20.

[0142] [Variation 2] Based on the reception history of the effectiveness evaluation results, the attention-requiring situation model storage unit 13 may perform a learning process such as sorting the attention-requiring situation models stored in the attention-requiring situation model storage unit 13. For example, the attention-requiring situation models that have not been evaluated as “effective” for a certain period of time (for example, two years) may be deleted from the attention-requiring situation model storage unit 13.

[0143] In addition, when the mobility support device 30 receives validity evaluation results indicating “valid” or “invalid” from the information collection system 10, models requiring attention that have a high proportion of “invalid” evaluations may be deleted from the model requiring attention situation memory unit 13.

[0144] In addition, the information collection system 10 may lower the reliability of the pointer ID of a model of a situation requiring attention that has a high proportion of ``invalid'' evaluations, or may not adopt a model of a situation requiring attention that has a pointer ID with a low reliability.

[0145] Furthermore, the information collection system 10 may set the amount of reward to be given to the person who pointed out a problem based on the reception history of the effectiveness evaluation result. For example, the information collection system 10 may increase the reliability of the person who pointed out a problem having a high ratio of evaluations of "effective" and may give a higher reward to the person who pointed out a problem having a highly reliable person ID than to other people who pointed out a problem.

[0146] <Embodiment 3> An operator of the mobility assistance system may operate the mobility assistance system as a business, and charge clients, who are users of the mobility assistance devices 30, a delivery fee for the caution-requiring situation model.

[0147] Fig. 20 is a diagram showing the configuration of a travel assistance system according to embodiment 3. The configuration of the travel assistance system in Fig. 20 is obtained by adding a charging unit 17 to the caution-requiring situation indicating device 20 in addition to the configuration in Fig. 1.

[0148] The charging unit 17 concludes a contract for the distribution of the caution-requiring situation model with the mobility support device 30 of the client, and charges the contracted mobility support device 30 a distribution fee for the caution-requiring situation model. The information distribution contract is concluded by the client operating the mobility support device 30. For example, a unit charge is set for a unit period such as one month.

[0149] Also, a business model in which the operator of the mobility support system rents the mobility support device 30 to a client is conceivable. In this case, the billing unit 17 of the information collection system 10 bills the client who has signed a rental contract for the mobility support device 30 for the rental fee of the mobility support device 30 in addition to the delivery fee for the caution-requiring situation model. The billing unit 17 may also apply a special fee system, such as a flat rate system, to the client who has been rented the mobility support device 30.

[0150] When the information distribution unit 14 receives a distribution request for a model of a caution-requiring situation from a mobility support device 30 with which the information distribution unit 14 has made a contract, the information distribution unit 14 distributes the model of a caution-requiring situation to the mobility support device 30 .

[0151] [Variation 1] The attention-requiring situation model may be classified by one or more of geographical type, mobile object type, and usage type, and the information distribution unit 14 may distribute the attention-requiring situation model according to a distribution unit specified by the mobility support device 30 to the mobility support device 30. In this case, the billing unit 17 bills the mobility support device 30 for a distribution fee according to the distribution unit of the attention-requiring situation model distributed by the information distribution unit 14. The distribution unit is set based on the distribution period of the attention-requiring situation model and the type of the attention-requiring situation model to be distributed.

[0152] When the caution-required situation model is classified by geographic type, the geographic type of the caution-required situation model is determined according to the location of the caution-required target point in the caution-required situation model, and may be determined, for example, by administrative division such as prefecture, state, country, etc., or by sea area if the mobile body is a ship. The wider the area to which the geographic type of the caution-required situation model to be distributed belongs, the higher the distribution fee for the caution-required situation model may be.

[0153] The geographical type of the caution situation model may be determined for each road type. The road types include expressways, general national roads, urban roads, mountain roads, etc. The geographical type may be a combination of an administrative division and a road type.

[0154] In addition, the modified example in which a caution-requiring situation model according to a delivery unit specified by the mobility support device 30 is delivered to the mobility support device 30 can contribute to reducing communication resources, and therefore may be applied to other embodiments other than embodiment 3.

[0155] [Variation 2] The caution-required situation models may be classified according to the target mobile object type. The mobile object types of the caution-required situation models may be, for example, for pedestrians, for light vehicles, for passenger cars, for buses, for trucks, for special vehicles, for ships, for aircraft, etc. The higher the accident occurrence rate of the mobile object type of the caution-required situation model to be distributed, the higher the distribution fee for the caution-required situation model may be.

[0156] [Variation 3] The caution-required situation models may be classified according to the use type. The use types of the caution-required situation models are home delivery, moving, pick-up and drop-off, transporting luggage, transporting animals, etc. The delivery fee for the caution-required situation model may be changed according to the use type of the delivered caution-required situation model.

[0157] [Variation 4] After the distribution contract for the caution-requiring situation model expires, the distribution of the caution-requiring situation model may be restricted, for example, by not distributing new caution-requiring situation models but allowing the use of the mobility support device 30 using the caution-requiring situation model that has already been distributed, and it is not necessarily necessary to prohibit the use of the mobility support device 30.

[0158] [Variation 5] The contract for distribution of the caution-required situation model is not limited to being concluded for each mobility support device 30, but may be concluded collectively with a business operator (e.g., a taxi company, a transportation company, a driving school operator, etc.) that manages multiple mobility support devices 30. The business operator is not limited to a business operator that owns multiple mobility support devices 30, but may be a business operator that only manages multiple mobility support devices 30, such as an insurance company.

[0159] [Variation 6] In the fifth modification, the business operator, which is the client, may be an operator that owns the pointer vehicle 200 equipped with the attention-requiring situation indicating device 20, and the driver of the pointer vehicle 200, i.e., the pointer, may be an employee of the business operator. In this case, the reward may not be paid for each attention-requiring situation indicating device 20, but may be paid in a lump sum to the business operator. Furthermore, the billing unit 17 of the information collection system 10 may charge the client by deducting the amount of reward for the attention-requiring situation pointed out by the employee from the amount of the delivery fee for the attention-requiring situation model. The pointer vehicle 200 and the client vehicle 300 may be the same vehicle.

[0160] [Variation 7] When the mobility support device 30 automatically judges the validity of the notification, the basic fee for the delivery fee of the model of the caution-requiring situation may be set to a low price, and an amount according to the number of times the model of the caution-requiring situation is evaluated as "valid" may be added. In order to reduce the delivery fee, it is effective that the driver of the client vehicle 300 will try to drive safely so as to notice the caution-requiring situation before the notification.

[0161] [Variation 8] When the operator of the mobility support system rents the mobility support device 30 to a client, the program of the rented mobility support device 30 may be updated from the information collection system 10. By managing the program of the mobility support device 30 on the information collection system 10 side, centralized management of services becomes possible. In addition, since the mobility support device 30 can also centrally manage the HMI (Human Machine Interface) for setting the billing conditions and distribution conditions, an information collection system 10 and a mobility support system with excellent maintainability can be realized.

[0162] [Variation 9] A business model in which the operator of the mobility assistance system rents out the caution-required situation indicating device 20 to the person who indicates the caution-required situation may also be considered. The information collection system 10 performs terminal authentication with the caution-required situation indicating device 20, so that information can be exchanged only with trusted caution-required situation indicating devices 20. Furthermore, by performing a process of rewriting the program of the caution-required situation indicating device 20 from the information collection system 10 at an appropriate timing, it is possible to realize uniformity and improvement of the performance of the caution-required situation indicating device 20.

[0163] Furthermore, the administrator of the information collection system 10 may rent both the caution-requiring situation indicating device 20 and the mobility assistance device 30 as a single device.

[0164] <Fourth embodiment> One possible business model for the mobility assistance system is for the mobility assistance system to be operated by an insurance company that issues insurance related to mobility, such as automobile insurance.

[0165] Fig. 21 is a diagram showing the configuration of a travel assistance system according to embodiment 3. The configuration of the travel assistance system in Fig. 21 is obtained by adding an insurance contract management unit 18 to the information collection system 10 in addition to the configuration in Fig. 1.

[0166] The insurance contract management unit 18 manages information on clients who are policyholders who have signed insurance contracts with the insurance company that operates the information collection system 10. The insurance contract management unit 18 registers the IDs of the mobility support devices 30 mounted on the client vehicles 300 of the clients who have signed insurance contracts.

[0167] When the information distribution unit 14 receives a request to distribute a model of a situation requiring caution from a mobility support device 30, it authenticates the ID of the mobility support device 30 that sent the distribution request, and if it can authenticate that the device is the mobility support device 30 of the insurance policyholder, it distributes the model of a situation requiring caution.

[0168] The travel assistance system according to the fourth embodiment is expected to prevent accidents and reduce insurance payments by providing travel assistance to clients who are policyholders who have signed contracts with insurance companies. In addition, the policyholders can receive high-quality travel assistance services from the insurance companies.

[0169] [Variation 1] The insurance contract management unit 18 may manage information of the insured who reports a situation, in addition to information of the client who reports a situation and has signed an insurance contract with the insurance company that operates the information collection system 10. In this case, the insurance contract management unit 18 registers the ID of the mobility support device 30 mounted on the client vehicle 300 of the client who has signed an insurance contract, and the ID of the caution-required situation reporting device 20 mounted on the reporter vehicle 200 of the reporter who has signed an insurance contract.

[0170] The policyholder may be both the client and the person who reports the incident. In other words, the same policyholder may be the driver of both the person who reports the incident and the client vehicle 300, or the person who reports the incident and the client vehicle 300 may be the same vehicle.

[0171] When a caution-required situation model corresponding to caution-required situation indication information provided by a reviewer who is a policyholder is evaluated as "valid," the reward provision unit 16 of the information collection system 10 may provide, as a reward, favorable contract conditions, such as raising the insurance grade of the policyholder or discounting the insurance premium, via the insurance contract management unit 18. This has the effect of allowing the insurance company operating the information collection system 10 to gather excellent caution-required situation indication information.

[0172] [Variation 2] An insurance company that operates a mobility assistance system may rent the mobility assistance device 30 to its clients, who are policyholders, thereby enabling the insurance company to provide mobility assistance services of consistent quality to its policyholders.

[0173] As in the above-mentioned modified example 1, when the insurance policyholder is both the client and the person who issues the notice, the attention-requiring situation indicating device 20 and the mobility support device 30 may be configured as an integrated unit. Recently, insurance companies may rent drive recorders to insurance policyholders. For example, as shown in FIG. 22, an insurance company may rent to an insurance policyholder a multi-function drive recorder 40 incorporating the attention-requiring situation indicating device 20 and the mobility support device 30, together with a situation recording device 41 that records the situation when the vehicle is traveling. This realizes an inexpensive and compact mobility support system.

[0174] 22 is connected to a positioning device 401, a periphery detection device 402, a driver monitoring device 403, an operation device 404, and a notification device 405 provided in a vehicle 400 of a policyholder who is a client and a reporter (hereinafter referred to as "policyholder vehicle"). These may have the same functions as the positioning device 201, the driver monitoring device 203, the driver monitoring device 203, or the operation device 204 of the reporter vehicle 200 described above, or the positioning device 301, the periphery detection device 302, the driver monitoring device 303, the operation device 304, or the notification device 305 of the client vehicle 300. In addition, some or all of the positioning device 401, the periphery detection device 402, the driver monitoring device 403, the operation device 404, and the notification device 405 may be built into the multifunctional drive recorder 40.

[0175] The situation recording device 41 records, on a recording medium, information on the position of the policyholder's vehicle 400 measured by the positioning device 401 while the policyholder's vehicle 400 is traveling, information on the surrounding conditions of the policyholder's vehicle 400 detected by the surroundings detection device 402 (e.g., video and audio around the vehicle), and information on the state of the driver of the policyholder's vehicle 400 detected by the driver monitoring device 403 (e.g., video of the driver and audio inside the vehicle). The caution-required situation indicating device 20 generates caution-required situation indication information including information on the caution-required situation indicated by the driver of the policyholder's vehicle 400, and transmits it to the information collecting system 10. The travel assistance device 30 provides driving assistance for the policyholder's vehicle 400 based on the caution-required situation model distributed from the information collecting system 10.

[0176] [Variation 3] When the mobility support device 30 monitors the driving operation of the driver of the client vehicle 300 who is the policyholder and notifies the driver of a situation requiring caution, if the driver performs a driving operation according to the contents of the notification, that is, a driving operation to avoid the notified situation requiring caution, the driver (policyholder) may be rewarded with a reduction in insurance premium. This has the effect of contributing to safe driving by the client.

[0177] <Hardware configuration example> 23 and 24 are diagrams showing examples of the hardware configuration of the information collection system 10. The functions of the components of the information collection system 10 shown in FIG. 1 and the like are realized, for example, by a processing circuit 50 shown in FIG. 23. That is, the information collection system 10 includes a processing circuit 50 for collecting, from the attention-requiring situation indicating device 20, attention-requiring situation indication information including information on the attention-requiring situation indicated by an indicater who is a user of the attention-requiring situation indicating device 20 and an identifier of the indicater, creating an attention-requiring situation model that is a model of the attention-requiring situation based on the collected attention-requiring situation indication information, storing the attention-requiring situation model, delivering the attention-requiring situation model to the travel support device 30, receiving an evaluation result of the effectiveness of the attention-requiring situation model from the travel support device 30, and giving a reward to the indicater of the attention-requiring situation indication information on which the attention-requiring situation model evaluated as effective is based. The processing circuit 50 may be dedicated hardware, or may be configured using a processor (also called a central processing unit (CPU), processing device, arithmetic device, microprocessor, microcomputer, or DSP (Digital Signal Processor)) that executes a program stored in a memory.

[0178] When the processing circuit 50 is a dedicated hardware, the processing circuit 50 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination of these. Each function of the components of the information collection system 10 may be realized by an individual processing circuit, or the functions may be realized collectively by a single processing circuit.

[0179] 24 shows an example of a hardware configuration of the information collecting system 10 in the case where the processing circuit 50 is configured using a processor 51 that executes a program. In this case, the functions of the components of the information collecting system 10 are realized by software, etc. (software, firmware, or a combination of software and firmware). The software, etc. is written as a program and stored in the memory 52. ​​The processor 51 realizes the function of each part by reading and executing the program stored in the memory 52. That is, the information collection system 10 includes a memory 52 for storing a program that, when executed by the processor 51, results in the execution of the following processes: collecting, from the attention-requiring situation indicating device 20, attention-requiring situation indication information including information on attention-requiring situations indicated by an indicater who is a user of the attention-requiring situation indicating device 20 and an identifier of the indicater; creating an attention-requiring situation model that is a model of an attention-requiring situation based on the collected attention-requiring situation indication information; storing the attention-requiring situation model; delivering the attention-requiring situation model to the mobility support device 30; receiving from the mobility support device 30 a result of evaluating the effectiveness of the attention-requiring situation model; and giving a reward to the indicater of the attention-requiring situation indication information that was the basis of the attention-requiring situation model evaluated as effective. In other words, this program can be said to cause a computer to execute the procedure and method of the operation of the components of the information collection system 10.

[0180] Here, memory 52 may be, for example, a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a HDD (Hard Disk Drive), a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD (Digital Versatile Disc) and a drive device thereof, or any other storage medium that will be used in the future.

[0181] The above describes a configuration in which the functions of the components of the information collecting system 10 are realized either by hardware or software, etc. However, the present invention is not limited to this, and the information collecting system 10 may be configured such that some of the components are realized by dedicated hardware and other components are realized by software, etc. For example, it is possible to realize the functions of some of the components by the processing circuit 50 as dedicated hardware, and realize the functions of other components by the processing circuit 50 as the processor 51 reading and executing a program stored in the memory 52.

[0182] As described above, the information collection system 10 can realize each of the above-mentioned functions by hardware, software, or a combination of these.

[0183] It should be noted that the embodiments can be freely combined, and each embodiment can be modified or omitted as appropriate.

[0184] The above description is illustrative in all respects, and it is understood that numerous variations not illustrated can be envisioned. [Explanation of symbols]
