The priority presentation device 10 is an information processing device for presenting the priority of each of a plurality of judgment items used for judging the accident situation.

An accident situation is information representing the situation of an accident caused by one or more parties such as vehicles and pedestrians. The accident situation is, for example, the situation of an accident caused by contact between an object and another object. Objects are, for example, vehicles, pedestrians, animals, utility poles, walls, and the like. Vehicles are, for example, automobiles, bicycles, motorcycles, and the like.

A judgment item is an item used for judging an accident situation. In other words, the determination items are those items that can influence the determination of each of the parties' percentage of fault. The determination items are items that can determine each situation, such as own vehicle behavior, road conditions, opponent object behavior, road conditions, signal conditions, and the like. Specific examples of judgment items include collision opponent, traffic light color, crosswalk, pedestrian signal color, own vehicle speed, presence/absence of temporary stop, presence/absence of sudden acceleration, presence/absence of center line, etc., but are not limited to these. .

The accident situation data 30 is data representing an accident situation. The accident situation data 30 is, for example, an image of the accident situation, a sensor detection result of the accident situation, and the like. The image of the accident situation is, for example, a photographed image at the time of the accident, which is photographed by a photographing device mounted on the vehicle of the person involved in the accident or a photographing device installed at the accident site. A sensor detection result of an accident situation is, for example, a detection result detected by a sensor mounted on a vehicle of a party involved in the accident. Specifically, the detection result is, for example, data such as position, velocity, acceleration, voice, etc. by GPS (Global Positioning System).

The machine learning model 32 is a model that analyzes the accident situation data 30 and outputs analysis result information 34 that is the analysis result of the accident situation. As the machine learning model 32, a model using a known machine learning method such as CNN (convolutional neural network), SVM (support vector machine), or the like may be used.

FIG. 2B is a schematic diagram of an example of the data configuration of the analysis result information 34. As shown in FIG.

FIG. 2C is a schematic diagram of an example of the data configuration of the reliability information 36. As shown in FIG.

The reliability information 36 is information representing the reliability of each of multiple types of determination results for each determination item. Based on the analysis result information 34, the reliability acquisition unit 20A assigns a higher reliability to each of the plurality of types of corresponding determination results for each of the determination items as the likelihood of the determination result is higher. Generate information 36 .

Therefore, the reliability information 36 is information to which a higher degree of reliability is assigned to a determination result with a higher likelihood represented by the analysis result information 34 by the machine learning model 32 .

In the present embodiment, when the pedestrian traffic light detection result is used, the judgment result "yellow" of the judgment item "pedestrian traffic light color" means that the pedestrian traffic light color is green and blinks. do. In addition, when using the determination item "traffic light" (see the determination item "traffic light color" in FIG. 2C) as a substitute for the detection result of the pedestrian traffic light, the determination result of the determination item "traffic light" " yellow” is used as the determination result “yellow” of the determination item “pedestrian signal color”.

Returning to FIG. 1, the description continues. The reliability acquisition unit 20A outputs the acquired reliability information 36 to the reliability change amount calculation unit 20C and the judgment item priority calculation unit 20E.

The fault ratio acquisition unit 20B acquires fault ratio information representing the fault ratio corresponding to each of the plurality of types of judgment results for each of the plurality of judgment items from the fault ratio dictionary information.

The fault ratio dictionary information is information that defines the fault ratio of the parties to the accident for each accident situation represented by a combination of one or more judgment items. The percentage-of-fault dictionary information is determined in advance according to, for example, past cases and court precedents.

The fault ratio acquisition unit 20B may read the fault ratio dictionary information 40 stored in the storage unit 12 and acquire the fault ratio information from the read fault ratio dictionary information 40 . The fault ratio acquisition unit 20</b>B may read the fault ratio dictionary information 40 from an external information processing device via the communication unit 14 and acquire the fault ratio information from the read fault ratio dictionary information 40 .

FIG. 3A is a schematic diagram showing an example of the data configuration of the fault ratio dictionary information 40. As shown in FIG. For example, the fault percentage dictionary information 40 is specified by a combination of one or more judgment items such as pedestrians, cars, traffic lights, etc., and judgment results such as blue, red, etc. for each of these judgment items. This information defines the percentage of fault of the parties involved for each accident situation.

The fault ratio acquisition unit 20B acquires fault ratio information from the fault ratio dictionary information 40 .

FIG. 3B is a schematic diagram showing an example of the data configuration of the fault ratio information 42. As shown in FIG. The fault ratio information 42 is information representing fault ratios corresponding to each of a plurality of types of judgment results for each of a plurality of judgment items.

For example, the fault ratio information 42 is data that associates an accident situation represented by a combination of one or more judgment items and judgment results for the judgment items with the fault ratios of the parties involved. As an example in FIG. 3B, an accident represented by the determination item "pedestrian" determination result "present", the determination item "pedestrian signal color" determination result "red", and the determination item "traffic light color" determination result "blue" Indicates the percentage of fault corresponding to the situation. Further, in FIG. 3B, as an example, the judgment item "pedestrian" judgment result "present", the judgment item "pedestrian signal color" judgment result "yellow", and the judgment item "traffic light color" judgment result "blue" are displayed. Indicates the percentage of fault corresponding to the accident situation. In addition, in FIG. 3B, as an example, the determination result of the determination item “pedestrian” is “present”, the determination result of the determination item “pedestrian signal color” is “red”, and the determination item “traffic light color” is “blue”. indicates the percentage of negligence corresponding to the accident situation.

It should be noted that the correspondence between the combination of the determination item and the determination result represented by the accident situation registered in the fault rate information 42 and the fault rate is not limited to the form shown in FIG. 3B.

The fault ratio acquisition unit 20B may generate and acquire the fault ratio information 42 by extracting the fault ratio corresponding to each of the plurality of types of judgment results for each of the plurality of judgment items from the fault ratio dictionary information 40. .

Returning to FIG. 1, the description continues. The fault ratio acquisition unit 20B outputs the acquired fault ratio information 42 to the fault ratio change amount calculation unit 20D.

Based on the reliability information 36, the reliability change amount calculation unit 20C calculates the absolute difference in reliability between each of the corresponding plurality of types of determination results and the other types of determination results for each of the plurality of determination items. The value is calculated as the amount of reliability change.

Description will be made with reference to FIG. 2C. For example, the determination item “pedestrian signal color” will be described. The reliability change amount calculation unit 20C calculates the reliability levels of “0.5”, “0.5”, “0.5”, “0. 08", "0.42". Then, the reliability change amount calculation unit 20C calculates the absolute value “0.42” of the reliability difference between the determination result “red” and the determination result “yellow”, and the absolute value “0.42” between the determination result “red” and the determination result “blue”. The absolute value of the reliability difference "0.08" and the absolute value "0.34" of the reliability difference between the judgment result "yellow" and the judgment result "blue" are calculated for the judgment item "pedestrian signal color" It is calculated as the amount of change in reliability. Similarly for the other determination items, the reliability change amount calculator 20C calculates the absolute value of the difference in reliability between the plurality of types of determination results corresponding to the determination item as the reliability change amount.

For each of the plurality of determination items, the reliability change amount calculation unit 20C calculates the reliability of any one pair or any plurality of pairs of determination results among the respective reliability of the corresponding plurality of types of determination results. The absolute value of the difference may be calculated as the reliability change amount.

In the present embodiment, the reliability change amount calculation unit 20C calculates, for each of a plurality of determination items, the difference in reliability between an arbitrary pair of determination results among the respective reliability levels of the corresponding plurality of types of determination results. A mode in which the absolute value is calculated as the reliability change amount of the determination item will be described as an example.

Specifically, in the present embodiment, the reliability change amount calculation unit 20C calculates the highest reliability and the next highest reliability among the reliability of each of the corresponding plurality of types of determination results for each of the plurality of determination items. The absolute value of the difference from the degree is calculated as the reliability change amount.

For example, the determination item “pedestrian signal color” will be described. In this case, the reliability change amount calculation unit 20C selects “red”, which is the highest reliability among the plurality of types of determination results “red”, “yellow”, and “blue” corresponding to the determination item “pedestrian signal color”. "0.5" and the second highest reliability "blue" "0.42", the absolute value of the difference "0.08", the judgment item "pedestrian It is calculated as the amount of change in the reliability of "signal color".

Returning to FIG. 1, the description continues. The reliability change amount calculation unit 20C combines the information representing each of the plurality of judgment items and the reliability change amount calculated for each of the plurality of judgment items with the fault ratio change amount calculation unit 20D and the judgment item priority calculation unit. Output to the section 20E.

Based on the fault ratio information 42, the fault ratio change amount calculation unit 20D calculates the absolute difference of the fault ratio between each of the corresponding plurality of types of judgment results and the other types of judgment results for each of the plurality of judgment items. The value is calculated as percent fault change.

Description will be made with reference to FIG. 3B. For example, the determination item “pedestrian signal color” will be described. The negligence ratio change amount calculation unit 20D calculates an arbitrary person (for example, a pedestrian) for each of a plurality of types of determination results "red", "yellow", and "blue" corresponding to the determination item "pedestrian signal color". Read the percentage of fault for Then, the fault ratio change amount calculation unit 20D calculates the absolute value “30%” of the difference in the fault ratio between the judgment result “blue” and the judgment result “yellow”, and the fault ratio between the judgment result “blue” and the judgment result “red”. The absolute value of the ratio difference of ``50%'' and the absolute value of the difference in reliability between the judgment result of ``yellow'' and the judgment result of ``red'' of ``20%'' are calculated as the change in negligence ratio for the judgment item ``pedestrian traffic light color''. Calculate as a quantity. Likewise for the other determination items, the fault ratio change amount calculator 20D calculates the absolute value of the difference in the fault ratio between the plurality of types of judgment results corresponding to the judgment item as the fault ratio change amount.

Note that, for each of the plurality of judgment items, the fault ratio change amount calculation unit 20D calculates the fault ratio of any one pair or any plurality of pairs of judgment results among the fault ratios of the corresponding plurality of types of judgment results. The absolute value of the difference may be calculated as the fault ratio change amount of the judgment item.

In this case, for each of the plurality of judgment items, the negligence ratio change amount calculation unit 20D uses the reliability change amount calculation unit 20C to calculate the reliability change amount among the negligence ratios of the corresponding plurality of types of judgment results. The absolute value of the difference in fault ratio between the judgment results used is calculated as the fault ratio change amount.

As described above, in the present embodiment, the negligence ratio change amount calculation unit 20D calculates the highest reliability and the next highest reliability among the respective reliability of the corresponding plurality of types of determination results for each of the plurality of determination items. The absolute value of the difference from the reliability is calculated as the reliability change amount. Therefore, in the present embodiment, the negligence ratio change amount calculation unit 20D calculates the negligence ratio corresponding to the determination result with the highest reliability and the judgment result with the second highest reliability for each of the plurality of determination items. The absolute value of the difference between the negligence ratio and the negligence ratio is calculated as the negligence ratio change amount.

For example, the determination item “pedestrian signal color” will be described. In this case, the negligence ratio change amount calculation unit 20D selects “red”, which is the highest reliability among the plurality of types of determination results “red”, “yellow”, and “blue” corresponding to the determination item “pedestrian traffic light color”. "50%", which is the absolute value of the difference between the pedestrian's fault rate "50%" corresponding to "" and the pedestrian fault rate "0%" corresponding to "blue", which has the next highest reliability. is calculated as the fault ratio change amount of the judgment item "pedestrian signal color".

Returning to FIG. 1, the description continues. The negligence ratio change amount calculation unit 20D outputs information representing each of the plurality of judgment items and the negligence ratio change amount calculated for each of the plurality of judgment items to the judgment item priority calculation unit 20E.

The determination item priority calculation unit 20E calculates the reliability of each of a plurality of types of determination results for each of a plurality of determination items used to determine an accident situation, and the reliability between different types of determination results in each of a plurality of determination items. Based on at least one of a reliability change amount representing a difference and a negligence ratio change amount representing a difference between different types of judgment results in each of the plurality of judgment items, each of the plurality of judgment items Calculate priority.

The determination item priority calculation unit 20E receives the reliability information 36 from the reliability acquisition unit 20A. Further, the determination item priority calculation unit 20E receives information representing each of the plurality of determination items and the reliability change amount calculated for each of the plurality of determination items from the reliability change amount calculation unit 20C. Further, the judgment item priority calculation unit 20E receives information representing each of the plurality of judgment items and the fault ratio change amount calculated for each of the plurality of judgment items from the fault ratio change amount calculation unit 20D.

Then, the determination item priority calculation unit 20E calculates the reliability of each of the plurality of types of determination results included in the reliability information 36, and the reliability index representing the difference in reliability between different types of determination results in each of the plurality of determination items. Using at least one of the degree change amount and the negligence ratio change amount representing the difference in the negligence ratio between different types of judgment results in each of the plurality of judgment items included in the negligence ratio information 42, the plurality of judgment items Calculate the priority of each of

Specifically, for each of a plurality of judgment items, the judgment item priority calculation unit 20E calculates the priority so that the lower the reliability is, the higher the priority is, the smaller the reliability change amount is, the higher the priority is, and the larger the fault percentage change amount is, the higher the priority is. do.

For example, the determination item priority calculation unit 20E identifies the highest reliability among the plurality of types of corresponding determination results for each of a plurality of determination items as the reliability of the determination item. Then, the determination item priority calculation unit 20E calculates a higher priority for each of the plurality of determination items as the specified reliability is lower.

Also, for example, the determination item priority calculation unit 20E calculates the priority for each determination item using the following formula (1).

Priority=(1/α)×β Expression (1)

In equation (1), α represents the amount of change in reliability, and β represents the amount of change in fault rate.

Further, the determination item priority calculation unit 20E may calculate the priority for each determination item using the following formula (2) or formula (3). In formulas (2) and (3), α and β have the same meanings as in formula (1).

Priority=(1−α)×β Expression (2)
Priority=(1/α)+β Expression (3)

In the above formulas (1) to (3), the larger the value, the higher the priority.

Note that α may represent the degree of reliability. Also, the above α may be an addition result, a multiplication result, or an average value of the reliability and the reliability change amount. In this case, for each of the plurality of determination items, the highest reliability among the corresponding plurality of types of determination results may be used as the reliability used for α.

As described above, in the present embodiment, for each of the plurality of determination items, the reliability change amount calculation unit 20C calculates the determination result with the highest reliability among the respective reliability of the corresponding plurality of types of determination results. An example will be described in which the absolute value of the difference in reliability between a pair of determination results and the determination result with the next highest reliability is calculated as the reliability change amount. In addition, for each of the plurality of judgment items, the negligence ratio change amount calculation unit 20D calculates the judgment result with the highest reliability and the judgment result with the second highest reliability among the negligence ratios of the corresponding plurality of types of judgment results. An example will be described in which the absolute value of the difference in the percentage of fault in a pair of determination results is calculated as the amount of change in the percentage of fault. Therefore, in the present embodiment, the determination item priority calculation unit 20E uses one reliability change amount and one fault percentage change amount calculated for one determination item to calculate the priority of the determination item. The form which carries out is demonstrated as an example.

Note that, as described above, the reliability change amount calculation unit 20C calculates the reliability of each of the corresponding plurality of types of determination results for each of the plurality of determination items. may be calculated as the reliability change amount. Similarly, for each of the plurality of judgment items, the negligence ratio change amount calculation unit 20D calculates each of a plurality of pairs of judgments having different combinations of judgment result types among the fault ratios of the corresponding plurality of types of judgment results. The absolute value of the resulting difference in fault ratio may be calculated as the fault ratio change amount.

In this case, the determination item priority calculation unit 20E calculates a plurality of reliability change amounts and a plurality of negligence ratio change amounts that differ in combination of types of determination results for one determination item. It is received from the portion 20C and the fault ratio change amount calculation portion 20D.

In this case, the determination item priority calculation unit 20E calculates the above formula ( 1) Calculate the provisional priority using any one of formulas (3). Then, the determination item priority calculation unit 20E calculates the total value, the average value, or the multiplication value of the provisional priority for each of the plurality of pairs of different combinations of the types of determination results calculated for one determination item, It may be calculated as a priority for the determination item.

Through these processes, the determination item priority calculation unit 20E calculates the priority of each of the plurality of determination items used to determine the accident situation.

The display control unit 20F displays the determination items in a display form according to the priority calculated by the determination item priority calculation unit 20E.

The determination grounds display field 52E includes, for example, a priority display field 52E1 and a display field 52E2 for evidence data of each determination item. The priority display field 52E1 displays, for example, a list of a plurality of determination items for which priorities have been calculated. The evidence data display column 52E2 for each determination item displays evidence data, detailed data, and the like used for determination of the determination item for each determination item.

For example, it is assumed that judgment items such as judgment items "own vehicle signal", "own vehicle movement", and "center line" are displayed. Then, it is assumed that the determination item "vehicle signal" has the highest priority, and "vehicle movement" and "center line" have lower priority in this order.

Then, it is assumed that the determination item "vehicle signal" has the highest priority, and "vehicle movement" and "center line" have lower priority in this order.

In this case, for example, the display control unit 20F highlights the “vehicle signal”, which is the determination item with the highest priority among the plurality of determination items displayed in the priority display column 52E1 (see area 52Ea). ). In addition, the display control unit 20F highlights the next-highest-priority determination item, "self-vehicle movement," in a color or the like that encourages attention next to the area 52Ea (see area 52Eb). Note that the display control unit 20F provides a plurality of priority threshold ranges in place of the highest priority, and highlights the priority determination items in each threshold range with a color corresponding to each threshold range. good too.

Further, the display control unit 20F may display all of the determination items included in the display screen 50 in a display form according to the priority.

Then, it is assumed that the determination item "vehicle signal" has the highest priority, and "vehicle movement" and "center line" have lower priority in this order.

In this case, for example, the display control unit 20F displays the “vehicle signal”, which is the determination item with the highest priority, in a display form different from that of the other determination items. Specifically, for example, as shown in FIG. 4C, the display control unit 20F displays a Among the plurality of displayed determination items, the determination item "vehicle signal" having the highest priority is selectively highlighted (see areas 52Ea, 52Ec, and 52Ca).

Further, the display control unit 20F may highlight all of the determination items included in the display screen 50 and display a plurality of determination items in descending order of priority.

For example, it is assumed that judgment items such as judgment items "own vehicle signal", "own vehicle movement", and "center line" are displayed. Then, it is assumed that the determination item "vehicle signal" has the highest priority, and "vehicle movement" and "center line" have lower priority in this order.

In this case, for example, the display control unit 20F selects, among a plurality of judgment items displayed in each of the priority display field 52E1, the evidence data display field 52E2 of each judgment item, and the judgment item list display field 52C, The "vehicle signal", which is the determination item with the highest priority, is highlighted (see areas 52Ea, 52Ec, and 52Ca). In addition, the display control unit 20F selects the next priority among the plurality of judgment items displayed in each of the priority display field 52E1, the evidence data display field 52E2 of each judgment item, and the judgment item list display field 52C. The "vehicle movement", which is a high-level judgment item, is then highlighted with a color or the like that encourages attention (see areas 52Eb, 52Ed, and 52Cb).

Further, the display control unit 20F may highlight and display the plurality of determination items included in the display screen 50 according to the priority, instead of arranging them in descending order of priority.

FIG. 4E is a schematic diagram of an example of the display screen 50D. A display screen 50E is an example of the display screen 50 displayed on the UI unit 16 by the display control unit 20F.

The display control unit 20F displays the display screen 50E on the UI unit 16, for example. As with the display screen 50A, the display screen 50E includes, for example, an accident basic information display field 52A, an accident situation diagram display field 52B, a judgment item list display field 52C, an accident information display field 52D, and a judgment basis display field 52E. .

For example, it is assumed that judgment items such as "vehicle signal", "vehicle movement", and "center line" are displayed. Then, it is assumed that the determination item "vehicle signal" has the highest priority, and "vehicle movement" and "center line" have lower priority in this order.

In this case, for example, the display control unit 20F selects, among a plurality of judgment items displayed in each of the priority display field 52E1, the evidence data display field 52E2 of each judgment item, and the judgment item list display field 52C, The "vehicle signal", which is the determination item with the highest priority, is highlighted (see areas 52Ea, 52Ec, and 52Ca). In addition, the display control unit 20F selects the next priority among the plurality of judgment items displayed in each of the priority display field 52E1, the evidence data display field 52E2 of each judgment item, and the judgment item list display field 52C. The "vehicle movement", which is a high-level judgment item, is then highlighted with a color or the like that encourages attention (see areas 52Eb, 52Ed, and 52Cb). At this time, the display control unit 20F displays a plurality of determination items included in at least one of the priority display column 52E1, the evidence data display column 52E2 of each determination item, and the determination item list display column 52C. may be arranged and displayed in an order different from the order of priority, as shown in FIG. 4E.

For example, it is assumed that judgment items such as judgment items "own vehicle signal", "own vehicle movement", and "center line" are displayed. Then, it is assumed that the determination item "vehicle signal" has the highest priority, and "vehicle movement" and "center line" have lower priority in this order. It is also assumed that the priority of the determination item "center line" is equal to or less than the threshold.

In this case, for example, the display control unit 20F may display the display screen 50F in which the determination result of the determination item "center line" whose priority is equal to or less than the threshold is not displayed (see area 52Cc). In this case, for example, the user may input any determination result in the area 52Cc by operating the UI unit 16 . The display control unit 20F that has received the input of the determination result may store the received determination result in association with the corresponding determination item.

Next, an example of the flow of information processing executed by the priority presentation device 10 of the embodiment will be described.

FIG. 5 is a flowchart showing an example of the flow of information processing executed by the priority presentation device 10 of this embodiment.

The reliability acquisition unit 20A acquires the reliability information 36 representing the reliability of each of the plurality of types of determination results for each of the plurality of determination items from the accident situation analysis result information 34 (step S100).

The fault ratio acquisition unit 20B acquires the fault ratio information 42 from the fault ratio dictionary information 40 (step S102).

The reliability change amount calculation unit 20C calculates the reliability change amount of each of the plurality of determination items based on the reliability information 36 acquired in step S100 (step S104).

Based on the fault ratio information 42 acquired in step S102, the fault ratio change amount calculator 20D calculates the fault ratio change amount for each of the plurality of determination items (step S106).

The determination item priority calculation unit 20E calculates at least one of the reliability represented by the reliability information 36 acquired in step S100, the reliability change amount calculated in step S104, and the fault percentage change amount calculated in step S106. Based on one, the priority of each of the plurality of judgment items is calculated (step S108).

The display control unit 20F displays the determination items in a display form according to the priority calculated for each of the plurality of determination items in step S108 (step S110). Then, the routine ends.

As described above, the priority presentation device 10 of this embodiment includes the determination item priority calculation unit 20E. The determination item priority calculation unit 20E calculates the reliability of each of a plurality of types of determination results for each of a plurality of determination items used to determine an accident situation, and the reliability between different types of determination results in each of a plurality of determination items. Based on at least one of a reliability change amount representing a difference and a negligence ratio change amount representing a difference between different types of judgment results in each of the plurality of judgment items, each of the plurality of judgment items Calculate priority.

In the conventional technology, a plurality of judgment items are displayed in the same display format regardless of their importance. For this reason, in the conventional technology, the user does not know which determination item should be confirmed with priority, and it is necessary to confirm all of the plurality of determination items with the same attentiveness. Therefore, in the conventional technology, the confirmation operation by the user may become inefficient.

In addition, the reliability of the determination result for the determination item may vary depending on the performance of the machine learning model that derived the determination result, the accuracy of the accident situation data used for the derivation, and the like. However, in the conventional technology, since a list of multiple determination items is only displayed, it is difficult for the user to determine which determination item requires particular confirmation or correction. In addition, in the conventional technology, the user sometimes fails to confirm particularly important determination items. In other words, the conventional technology does not provide the judgment items of the accident situation in an efficient and confirmable manner.

On the other hand, in the priority presentation device 10 of the present embodiment, the determination item priority calculation unit 20E calculates the reliability of each of the plurality of types of determination results for each of the plurality of determination items used to determine the accident situation, the plurality of determination items At least the amount of change in reliability that represents the difference in reliability between different types of judgment results in each of the above, and the amount of change in negligence ratio that represents the difference in the proportion of fault between different types of judgment results in each of a plurality of judgment items. Based on one, the priority of each of the plurality of judgment items is calculated.

For example, it can be said that a judgment item including a judgment result with a low degree of reliability is a judgment item that particularly needs to be confirmed by the user, for reasons such as a high possibility of particularly affecting the determination of the percentage of fault. In addition, the smaller the reliability change amount, which is the difference in reliability among the plurality of types of determination results, the lower the certainty of the determination result. Further, the greater the difference in the percentage of negligence among the multiple types of determination results for the determination item, the greater the change in the percentage of negligence due to the difference in the determination results.

The priority presentation device 10 of the present embodiment calculates the priority of each of a plurality of judgment items based on at least one of the reliability, the amount of change in reliability, and the amount of change in fault ratio. Therefore, the priority presentation device 10 of the present embodiment can calculate a priority indicating that confirmation by the user is particularly required for each of the plurality of determination items. Therefore, the priority presentation device 10 of the present embodiment outputs each of the plurality of judgment items according to the calculated priority, thereby providing the judgment item to which the user should particularly pay attention. becomes.

Therefore, the priority presentation device 10 of the present embodiment can efficiently provide the judgment items of the accident situation so as to be confirmable.
