[0003] [Patent Document 1] JP 2019-197342 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the above circumstances, and one of its objects is to provide an information management device, an information management method, and a program that can improve the user's sense of satisfaction. [Means for solving the problem]

[0006] An information management device, an information management method, and a program according to the present invention employ the following configuration. (1): An information management device according to one embodiment of the present invention includes an acquisition unit that acquires information acquired by a vehicle or vehicle information that changes according to the driving of the vehicle acquired by an equipment mounted on the vehicle, an evaluation unit that evaluates the driving of a driver of the vehicle based on the vehicle information and predetermined judgment criteria, and an information processing unit that provides information indicating the result of the evaluation to a terminal device of the driver or a target user who is a specified user, and acquires feedback information on the result of the evaluation input by the target user from the terminal device.

[0007] (2) In the above aspect (1), a correction unit is provided that corrects the judgment criteria used in the fed-back evaluation in accordance with the feedback information.

[0008] (3): In the above aspect (1) or (2), a correction unit is provided that determines whether to correct the judgment criteria by placing more importance on feedback information of target users with high reliability among the target users than on feedback information of target users with low reliability.

[0009] (4): In the aspect (1) above, the vehicle information includes information indicating the behavior of the vehicle, information indicating the driver's operation of the vehicle, and images captured by an imaging unit mounted on the vehicle or the equipment.

[0012] (7): In the above aspect (6), when the correction unit acquires specific feedback information in an amount equal to or greater than a threshold, the correction unit corrects the judgment criteria used in the evaluation corresponding to the specific feedback information, and the specific feedback information is feedback information sent from a different target user and indicates that there is an error in the evaluation using the judgment criteria for the same location information.

[0013] (8): In the above aspect (7), the judgment criterion is that the turn indicator was not flashed in a manner corresponding to the turning direction when turning right or left, and the specific feedback information is feedback information that the turn indicator was not flashed when turning right or left, when flashing of the turn indicator is not necessary.

[0014] (9): In the above aspect (6), after the judgment criterion is corrected, the evaluation unit performs an evaluation using the judgment criterion before correction, and the correction unit performs a judgment on the evaluation using the judgment criterion before correction. If the evaluation of the target user in the location information corresponding to the judgment criterion before correction exceeds a threshold and the evaluations exceeding the threshold have been counted a predetermined number of times or more, the judgment criterion is restored to the judgment criterion before correction and the restored judgment criterion is used by the evaluation unit.

[0015] (10): In the above aspect (6), when the evaluation of the target user for the same location information is below a threshold and the evaluation below the threshold has been counted a predetermined number of times or more, the correction unit corrects the judgment criterion corresponding to the evaluation below the threshold.

[0016] (11): In any of the above aspects (6) to (10), the correction unit causes a display unit to display information encouraging the user to correct the judgment criteria in response to the feedback information, and when an administrator operates an operation unit in response to the display to correct the judgment criteria, the correction unit corrects the judgment criteria.

[0026] Hereinafter, an embodiment of an information management apparatus, an information management method, and a program according to the present invention will be described with reference to the drawings.

[0027] [overview] The information management device, information management method, and program of this embodiment monitor the driving of elderly drivers and drivers who are not accustomed to driving, and evaluate their driving. The results of the evaluation are provided to a terminal device of a target user who is the driver or a person related to the driver. The target user can return feedback information in response to the evaluation, which improves the driver's sense of satisfaction. Furthermore, the target user can check the evaluation and provide feedback, thereby enhancing metacognitive function.

[0028] The information management device of this embodiment includes an acquisition unit that acquires vehicle information that changes according to the driving of the vehicle acquired by information acquired by a vehicle or equipment installed in the vehicle, an evaluation unit that evaluates the driving of the driver of the vehicle based on the vehicle information and predetermined judgment criteria, and an information processing unit that provides information indicating the result of the evaluation to a terminal device of the driver or a target user who is a specified user, and acquires feedback information on the result of the evaluation input by the target user from the terminal device.

[0029] The vehicle information includes information indicating the behavior of the vehicle, information indicating the driver's operation of the vehicle, and an image captured by an image capturing unit mounted on the vehicle or the device. The information indicating the behavior of the vehicle includes various information such as acceleration, speed, and turning degree. The vehicle information may be a part of the above information.

[0030] As described above, the target users can provide feedback on the evaluation, which increases the target users' sense of satisfaction.

[0031] The information management device also includes a correction unit that corrects the judgment criteria used in the fed back evaluation in accordance with the feedback information. Correction refers to changing the judgment criteria, such as deleting all or part of the judgment criteria, or changing all or part of the judgment criteria. By correcting the judgment criteria in accordance with feedback information on the evaluation from the target user as described above, the information management device can perform evaluation using judgment criteria that are more suitable for the actual environment.

[0032] [Function configuration] 1 is a configuration diagram of an information management system 1. The information management system includes, for example, a vehicle 10, a terminal device 20, and an information management device 100.

[0033] [vehicle] The vehicle 10 is a target vehicle 10 that communicates with the information management device 100. The vehicle 10 is, for example, a two-wheeled, three-wheeled, four-wheeled, or other vehicle. Note that, instead of the vehicle 10, the information management system 1 may use another device mounted on the vehicle 10 or a terminal device such as a smartphone attached to the vehicle 10 by the driver. This terminal device may be, for example, a device that acquires various information (vehicle information) from the vehicle 10 by wireless or wired communication with the vehicle 10 or an in-vehicle device mounted on the vehicle 10. Also, the present embodiment may be applied to a moving body other than a vehicle instead of a vehicle.

[0034] [Terminal Device] The terminal device 20 is a computer device that can execute various processes using a processor and has a communication function and an input / output function, such as a smartphone, a tablet terminal, or a personal computer. The terminal device 20 may be equipped with an application program used in the information management system 1, and execute various processes by a processor such as a CPU (Central Processing Unit) of the terminal device 20.

[0035] [Information management device] FIG. 2 is a diagram showing an example of a functional configuration of the information management device 100. The information management device 100 includes, for example, a communication unit 110, an acquisition unit 120, a recognition processing unit 130, an evaluation unit 140, an information processing unit 150, a correction unit 160, and a storage unit 190. The components other than the communication unit 110 and the storage unit 190 are realized by, for example, a hardware processor such as a CPU executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transient storage medium) such as an HDD (Hard Disk Drive) or a flash memory, or may be stored in a removable storage medium (a non-transient storage medium) such as a DVD or a CD-ROM, and may be installed by mounting the storage medium in a drive device. It should be noted that some or all of the functions of the information management device 100 may be installed in the vehicle 10 or the terminal device 20 .

[0036] The storage unit 190 stores vehicle information 192, judgment criterion information 194, feedback information (FB information) 196, and reliability information 198. The details of these pieces of information will be described later.

[0037] The communication unit 110 is a communication interface and communicates with the vehicle 10 and the terminal device 20 via the network NW.

[0038] The acquisition unit 120 acquires vehicle information (described later) from the vehicle 10 at predetermined time intervals. The recognition processing unit 130, for example, analyzes an image included in the vehicle information 192 to recognize objects included in the image and information indicated by the objects. The recognition processing unit 130, for example, recognizes road signs and the meanings of road signs from the image. The meanings of road signs include, for example, the legal speed limits indicated by road signs. The recognition processing unit 130, for example, recognizes surrounding vehicles such as a vehicle ahead, road dividing lines, traffic light status, and the like from the image.

[0039] The evaluation unit 140 evaluates the driving of the driver of the vehicle 10 based on the vehicle information 192 and preset judgment criteria (described later). The evaluation unit 140 evaluates the quality of the driving of the driver in a predetermined section or a predetermined time, and derives a score. For example, the evaluation unit 140 derives a higher evaluation or score when the driving is performed in a manner that does not satisfy the judgment criteria.

[0040] The information processing unit 150 provides information indicating the evaluation results to the terminal device 20 of the target user, which is the driver or a specified user (or the driver's family member, acquaintance, etc.), and obtains feedback information on the evaluation results entered by the target user from the terminal device 20.

[0041] The modification unit 160 modifies the judgment criteria used in the fed-back evaluation in accordance with the feedback information.

[0042] [Vehicle information] FIG. 3 is a diagram showing an example of the vehicle information 192. The vehicle information 192 is information in which, for example, the position information of the vehicle 10, information indicating the behavior of the vehicle (speed, acceleration, steering angle, yaw rate, etc.), operation information (information indicating the driver's operation), indicator information, images, sensing information, etc. are associated with a user ID or a vehicle ID. The operation information is information regarding the driver's operation, such as the operation mode (for example, the steering degree) of the accelerator pedal, the brake pedal, the steering wheel, etc., and the operation mode of other vehicle devices and operators. The indicator information is information indicating the operating state of the direction indicator. The image is an image captured by an imaging unit mounted on the vehicle 10 for capturing an image of the periphery of the vehicle 10. The sensing information is information detected by a radar device, LIDAR, etc. mounted on the vehicle 10. In the vehicle information 192, some of the above information may be omitted.

[0043] [Judgment criteria information] 4 is a diagram showing an example of the judgment criteria information 194. The judgment criteria information 194 includes, for example, a plurality of judgment criteria. The judgment criteria are criteria for the vehicle 10 violating traffic laws and regulations, criteria for violation of manners, and the like. The judgment criteria are, for example, that the vehicle 10 has traveled outside of road dividing lines, that the vehicle 10 has traveled faster than the legal speed limit, and the like. This judgment is made based on information obtained from an image acquired by the vehicle 10 (road signs, road dividing lines) and the position of the vehicle 10.

[0044] For example, the recognition processing unit 130 virtually superimposes the actual position of the vehicle 10 on the image based on a predetermined algorithm to determine whether the vehicle 10 is traveling outside the lane markings. For example, if the vehicle 10 continues to travel outside the lane markings for a predetermined period of time, or if the vehicle 10 travels outside the lane markings a threshold or more times in a predetermined period of time, the evaluation unit 140 determines that the determination criterion is met.

[0045] For example, the recognition processing unit 130 recognizes the meaning of a road sign in an image. If the vehicle 10 behaves in a manner that violates the rules of the road sign, the evaluation unit 140 determines that the judgment criterion is met. For example, if the vehicle 10 travels for a predetermined period of time at a speed that exceeds the legal speed limit indicated by the road sign, the evaluation unit 140 determines that the judgment criterion is met.

[0046] In addition, when the recognition processing unit 130 recognizes the state of the signal from the image, and the vehicle 10 behaves differently from the behavior corresponding to the signal state, the evaluation unit 140 may determine that the judgment criterion is satisfied. An example of a behavior different from the behavior corresponding to the signal state is not starting smoothly even when the light turns green. When the recognition processing unit 130 recognizes the position of the vehicle ahead from the image, and the vehicle 10 does not keep a sufficient distance from the vehicle ahead, the evaluation unit 140 may determine that the judgment criterion is satisfied.

[0047] The judgment criterion is a judgment criterion associated with each piece of position information, the vehicle information 192 includes the position information of the vehicle 10, and the evaluation unit 140 evaluates the driver using the judgment criterion corresponding to the position information of the vehicle information 192. The evaluation unit 140 may judge that the judgment criterion is satisfied when the steering angle satisfies the criterion in a preset area and the turn indicator does not blink according to the steering angle. For example, when a right turn or left turn is made without blinking the turn indicator at an intersection or a T-junction, the evaluation unit 140 judges that the judgment criterion is satisfied. More specifically, when the operation angle changes in a manner such as a predefined right turn or left turn and the turn indicator blinks according to the change, it is judged that the turn indicator is appropriately operated at the time of right turn or left turn and the right turn or left turn is made, and when the operation angle changes in a manner such as a predefined right turn or left turn and the turn indicator does not blink according to the change, it is judged that the turn indicator is not appropriately operated at the time of right turn or left turn and the right turn or left turn is made.

[0048] In the above example, the predetermined area (position information) is described as being included in the judgment criteria, but the predetermined area (position information) may be excluded from the judgment criteria. In this case, the evaluation unit 140 may determine that the judgment criteria are met when the change in the steering angle and the operation state of the turn signal satisfy the set criteria (for example, when the turn signal does not operate in response to the change in the steering angle).

[0049] In addition, the condition that the steering angle satisfies the criteria may be omitted. In this case, if the turn signal does not flash in the area A (for example, a predetermined intersection), it is determined that the criteria is not satisfied.

[0050] [Cost and erroneous judgment] When making the above judgment, it is costly to use high-precision map information that stores detailed road shapes, road structures, etc. High-precision map information is updated relatively frequently, and uploading high-precision map information for each update incurs costs.

[0051] In this embodiment, an information management system 1 that can perform accurate judgment without incurring costs is provided. In this embodiment, driving can be evaluated with high accuracy without using map information such as high-precision map information.

[0052] When the evaluation unit 140 determines that the judgment criterion is not satisfied without using map information, in this embodiment, the judgment may be correct, but may be incorrect. For example, a case where the driver does not blink the turn indicator will be described. FIG. 5 is a diagram showing an example of a scene where the judgment is correct. As shown in FIG. 5, when the vehicle 10 turns right at an intersection without blinking the turn indicator, the evaluation unit 140 determines that the judgment criterion is satisfied. In this case, the judgment is correct.

[0053] Fig. 6 is a diagram showing an example of a scene in which the determination is incorrect. As shown in Fig. 6, when the vehicle 10 runs along the road without blinking the turn indicator, the evaluation unit 140 determines that the vehicle 10 turns right without blinking the turn indicator, and therefore satisfies the determination criterion. In this way, in this embodiment, an erroneous determination may be made.

[0054] As described above, in this embodiment, since there is a possibility of erroneous determination, the information management device 100 provides the terminal device 20 with the result of the determination and content for receiving feedback information on the result of the determination. Fig. 7 is a diagram showing an example of content C for receiving feedback information. The content C includes, for example, information such as an inquiry about the reason why the turn indicator was not flashed and the position of the vehicle 10 in the map information for which the turn indicator was not flashed.

[0055] For example, the following (1) to (3) are provided, and when the user operates the terminal device 20 to select (1) to (3) and presses the send button, the reason for the selection is transmitted to the information management device 100. (1) Although they knew it was necessary, they did not activate it. (2) I overlooked it. (3) The location was such that an indicator was not needed (a misjudgment was made).

[0056] For example, the target user can give an opinion such as the above (3) regarding the evaluation. The transmitted information is stored in the information management device 100 and is used to correct the evaluation criteria. In this way, the target user can provide feedback, which improves the target user's sense of satisfaction. The process of correcting the evaluation criteria will be described in detail later.

[0057] [Sequence diagram] FIG. 8 is a diagram showing an example of a flow of processing executed by the information management system 1. First, the vehicle 10 acquires vehicle information (step S100), and transmits the acquired vehicle information to the information management device 100 (step S102). Next, the information management device 100 stores the transmitted vehicle information in the storage unit 190 as vehicle information 192 (step S104). Next, the information management device 100 evaluates the driver's driving based on the vehicle information 192 and the judgment criteria (step S106). Next, the information management device 100 transmits the result of the evaluation to the terminal device 20 (step S108).

[0058] Next, the terminal device 20 displays the evaluation result and the content for receiving feedback information on the display unit (step S110). Next, the terminal device 20 receives feedback information according to an operation by the user, and transmits the received feedback information to the information management device 100 (step S112). Next, the information management device 100 stores FB information 196, which is the transmitted feedback information, in the storage unit 190 (step S114). In this way, the information management device 100 receives, accumulates, and manages the feedback information.

[0059] [Flowchart for revising the criteria (1)] The correction unit 160 corrects the judgment criterion corresponding to the location information used for the feedback evaluation in response to obtaining feedback information indicating that the evaluation corresponding to the predetermined location information is erroneous. For example, when obtaining specific feedback information equal to or greater than a threshold, the correction unit 160 corrects the judgment criterion used for the evaluation corresponding to the specific feedback information. The specific feedback information is feedback information transmitted from a different target user and indicates that the evaluation using the judgment criterion for the same location information (e.g., area A in FIG. 4) is erroneous.

[0060] FIG. 9 is a flowchart (1) showing an example of the flow of processing executed by the information management device 100. First, the correction unit 160 accumulates information on erroneous judgment (step S200). The information on erroneous judgment is, for example, feedback information of (3) in FIG. 7. Next, the correction unit 160 judges whether or not the same erroneous judgment result is accumulated to a threshold value or more (step S202). The same erroneous judgment result is the same erroneous judgment result in the same place (area). If the same erroneous judgment result is not accumulated to a threshold value or more, step S204 is skipped, and the processing of one routine of this flowchart is terminated. If the same erroneous judgment result is accumulated to a threshold value or more, the correction unit 160 corrects the judgment criterion (step S204). This terminates the processing of one routine of this flowchart.

[0061] In the above example, correction unit 160 determines whether the result of the same erroneous determination is equal to or greater than a threshold value. Alternatively, however, the determination criterion may be changed when one piece of feedback information is received.

[0062] FIG. 10 is a diagram for explaining the correction of the judgment criteria. When the judgment in step S202 is positive as described above, the correction unit 160 deletes, for example, the judgment criterion 10 that the steering angle in the area A satisfies the criterion and the turn indicator does not blink according to the steering angle. In this way, when feedback information that does not blink the turn indicator when turning right or left, which is not necessary, is accumulated in response to the evaluation, the correction unit 160 deletes the judgment criterion regarding not blinking the turn indicator in a manner according to the turning direction when turning right or left. Thereby, the judgment criterion that causes an erroneous judgment is deleted, and the erroneous judgment is suppressed.

[0063] In the above example, the example of deleting the judgment criterion related to the turn signal has been described, but instead, other judgment criteria may be deleted in the same manner. For example, the judgment criterion related to the traveling of the vehicle may be deleted according to the road sign. FIG. 11 is a diagram for explaining a scene (1) in which an erroneous judgment is made. For example, it is assumed that the vehicle 10 travels on the road R1, and the road R2 exists parallel to the road R1. It is assumed that the legal speed limit of the road R1 is 60 km / h, and the legal speed limit of the road R2 is 30 km / h. It is assumed that the sign indicating the legal speed limit of the road R1 is installed at a position farther from the vehicle 10 than the sign indicating the legal speed limit of the road R2. In this case, the information management device 100 recognizes that the legal speed limit of the road R1 is 30 km / h, and when the vehicle 10 travels on the road R1 at a speed exceeding 30 km / h, it may judge that the vehicle 10 is speeding and may lower the evaluation. When an erroneous judgment is made on the judgment criterion related to such a legal speed and feedback is given, the judgment criterion related to the legal speed in this area may be deleted.

[0064] For example, the judgment criteria regarding the vehicle traveling outside the lane dividing lines may be deleted. Fig. 12 is a diagram for explaining a scene (2) in which an erroneous judgment is made. For example, even if road construction RC is being carried out in the lane in which the vehicle 10 is traveling and it is appropriate for the vehicle 10 to travel outside the lane dividing lines, if the vehicle 10 travels outside the lane dividing lines, the judgment criteria may be deemed satisfied and the evaluation may be low. When an erroneous judgment is made regarding the judgment criteria regarding such a road dividing line and the traveling position of the vehicle 10 and feedback is provided, the judgment criteria regarding the road dividing lines in this area and the traveling position of the vehicle 10 may be deleted.

[0065] In the above example, an example of road construction has been described, but in addition (or instead), similar processing may be performed in other situations where the environment changes dynamically. Examples of situations where the environment changes dynamically include various dynamic changes such as when new signs are installed, when the contents of signs are changed, when regulations regarding center lines, speed, and driving change depending on the time or period, and when the structure of the road has changed. In such situations, feedback information may be received, and the judgment criteria may be corrected, such as by deleting them, in response to the feedback.

[0066] In the above example, the judgment criterion has been described as being deleted, but instead of (in addition to) this, the judgment criterion may be changed. For example, in the example of FIG. 12 above, the condition that the judgment criterion is satisfied when the vehicle 10 travels outside the lane markings may be relaxed. The modification unit 160 may modify the judgment criterion to one that allows the vehicle 10 to travel outside the lane markings for a predetermined period of time, for example. Judgment criteria different from the above may also be modified according to the content of the judgment criterion.

[0067] As described above, the correction unit 160 changes the determination criteria based on the feedback information of the user, so that erroneous determination can be suppressed.

[0068] [Reverting modified criteria back to the original criteria] After the criterion is corrected, the evaluation unit 140 performs evaluation using the criterion before correction. The correction unit 160 performs judgment on the evaluation using the criterion before correction as follows. When the evaluation (e.g., score) in the location information corresponding to the criterion before correction of the target user exceeds a threshold and the correction unit 60 counts evaluations exceeding the threshold a predetermined number of times or more, the correction unit 60 returns the criterion to the criterion before correction and causes the evaluation unit 140 to use the returned criterion. In the above example, the number of evaluations by different target users may be compared with the threshold.

[0069] FIG. 13 is a diagram for explaining the process of returning the judgment criteria. For example, even if judgment criteria 1 relating to driving outside lane markings is deleted (removed from the regular judgment criteria) as shown in FIG. 13, the evaluation unit 140 continues the evaluation using judgment criteria 1. This evaluation result is an evaluation result that is not provided to the target user. When the number of evaluation results of judgment criteria 1 that exceed the threshold (evaluation results with scores that exceed the threshold) exceeds a predetermined number, the correction unit 160 returns judgment criteria 1 to the regular judgment criteria. This is because it is assumed that the road construction work has been completed in this case.

[0070] As described above, the modifying unit 160 returns the determination criterion modified in response to the road conditions to the original determination criterion, thereby making it possible to set a determination criterion in response to the road conditions.

[0071] [Processing using reliability] The modification unit 160 may determine whether to modify the judgment criteria by prioritizing feedback information of a target user with a high reliability among the target users over feedback information of a target user with a low reliability. For example, the modification unit 160 may refer to the reliability information 198 to determine whether to modify the judgment criteria.

[0072] FIG. 14 is a diagram showing an example of the contents of the reliability information 198. The reliability information 198 is information in which, for example, an evaluation score, reliability, and weighting of feedback information are assigned to a user ID (or a vehicle ID). The reliability is an index derived based on, for example, past evaluation scores and the appropriateness of feedback information. For example, the higher the past evaluation score, the higher the reliability is set, and the more appropriate the feedback information, the higher the reliability is set. For example, the reliability of a target user who has provided appropriate feedback information of a misjudgment is set high. For example, the administrator examines the feedback information of a misjudgment and sets a high reliability to a target user who has provided appropriate feedback. As described above, a high reliability is set to a good driver.

[0073] For example, the higher the reliability, the higher the weight of the feedback information is assigned. In the process of FIG. 9, when the same feedback information is accumulated to a threshold value or more, the modification unit 160 modifies the judgment criteria. In this process, a weight is added to the feedback information. For example, the feedback information of a target user with high reliability is counted twice as much, and the feedback information of a target user with low reliability is not counted.

[0074] As described above, the modification unit 160 determines whether the determination criterion needs to be modified using the reliability, thereby enabling the modification unit 160 to more accurately determine whether the determination criterion needs to be modified.

[0075] [Flowchart for revising the criteria (2)] FIG. 15 is a flowchart (2) showing an example of the flow of processing executed by the information management device 100. First, the correction unit 160 acquires the result of the evaluation by the evaluation unit 140 (step S300). Next, the correction unit 160 judges whether or not the evaluations that satisfy the judgment criterion have been performed at the same location more than the threshold (step S302). If the evaluations that satisfy the judgment criterion have not been performed at the same location more than the threshold, step S304 is skipped and the processing of one routine of this flowchart ends. If the evaluations that satisfy the judgment criterion have been performed at the same location more than the threshold, the correction unit 160 corrects the judgment criterion (step S204). This ends the processing of one routine of this flowchart.

[0076] For example, when the evaluations that satisfy the judgment criterion in the area A are equal to or greater than a threshold, the behavior of the vehicle that satisfies the judgment criterion may be a misjudgment, and therefore the correction unit 160 deletes the judgment criterion. "Above the threshold" may mean, for example, that the evaluations that satisfy the judgment criterion are equal to or greater than the threshold, and the ratio of the evaluations that satisfy the judgment criterion among the evaluations that do not satisfy the judgment criterion and the evaluations that satisfy the judgment criterion is equal to or greater than the threshold.

[0077] As described above, the information management device 100 can refer to the behaviors of a plurality of vehicles 10 and appropriately modify the determination criteria in accordance with the road conditions.

[0078] In the process of Fig. 15, the evaluation unit 140 and the correction unit 160 may also perform the following process to restore the criterion to its original state, as described above with reference to Fig. 13. After the criterion is corrected, the evaluation unit 140 performs evaluation using the criterion before correction. The correction unit 160 performs a judgment on the evaluation using the criterion before correction, and when the evaluation of the target user in the position information corresponding to the criterion before correction exceeds the threshold and the number of evaluations exceeding the threshold is counted a predetermined number of times or more, the correction unit 160 restores the criterion before correction and causes the evaluation unit 140 to use the restored criterion.

[0079] As described above, the modifying unit 160 returns the determination criterion modified in response to the road conditions to the original determination criterion, thereby making it possible to set a determination criterion in response to the road conditions.

[0080] In the above example, the modification unit 160 automatically modifies the judgment criteria, but instead of (or in addition to) this, when it is decided to modify the judgment criteria in response to feedback information, information prompting the user to modify the judgment criteria may be displayed on the display unit 170. When the administrator modifies the judgment criteria with reference to the display unit 170, the modification unit 160 may modify the judgment criteria. In this way, the modification unit 160 may modify the judgment criteria in response to the administrator's operation.

[0081] As described above, the information management device 100 receives feedback information on the evaluation and corrects the judgment criteria according to the received feedback information as necessary. For example, in this embodiment, even if information such as high-precision map information is not used, the driving of the driver can be appropriately evaluated by each of the above-mentioned processes. Even if the evaluation is not appropriate, for example, because the road environment changes depending on the time or period, or the judgment criteria are not appropriate, the information management device 100 receives feedback information, thereby improving the satisfaction of the target user. The information management device 100 can further provide better services to the target user by correcting the judgment criteria according to the feedback information. The information management device 100 of this embodiment can provide better services to the target user without using high-precision map information that is costly to purchase or update.

[0082] As described above, target users such as elderly people can check the evaluation and provide feedback, allowing them to reflect on their own driving and train their metacognition.

[0083] According to the embodiment described above, by providing an acquisition unit 120 that acquires vehicle information that changes according to the driving of the vehicle acquired by information acquired by the vehicle or equipment mounted on the vehicle, an evaluation unit 140 that evaluates the driving of the driver of the vehicle based on the vehicle information and preset judgment criteria, and an information processing unit 150 that provides information indicating the result of the evaluation to a terminal device of the driver or a target user who is a specified user, and acquires feedback information on the result of the evaluation input by the target user from the terminal device, the sense of satisfaction of the user can be improved.

[0084] The above-described embodiment can be expressed as follows. a storage medium for storing computer-readable instructions; a processor coupled to the storage medium; The processor executes the computer-readable instructions to: Acquire vehicle information that changes according to the traveling of the vehicle, the vehicle information being acquired by information acquired by a vehicle or an equipment mounted on the vehicle; Evaluating the driving of the driver of the vehicle based on the vehicle information and a preset judgment criterion; providing information indicating the result of the evaluation to a terminal device of the driver or a target user who is a predetermined user, and executing a process of acquiring feedback information on the result of the evaluation input by the target user from the terminal device; Information processing device.
