Abstract

A priority determination system includes: an anomaly obtainer that obtains a plurality of items of anomaly data; a circumstance obtainer that obtains a plurality of items of circumstance data; a risk value calculator that calculates a risk value; a priority determiner that determines the priority of each task based on the risk value; an outputter that provides an output based on the result of the determination; and a circumstance change notification manager that determines whether or not each of the plurality of items of anomaly data is circumstance change notification target data. The circumstance change notification manager requests a mobile object corresponding to anomaly data determined to be the circumstance change notification target data to send circumstance data after change. The risk value calculator recalculates the risk value based on the circumstance data after change. The priority determiner redetermines the priority of a task based on the recalculated risk value.

First claim

1 . A priority determination system comprising:
an anomaly obtainer that obtains a plurality of items of anomaly data each of which indicates an anomaly of a corresponding one of a plurality of mobile objects; a circumstance obtainer that obtains a plurality of items of circumstance data each of which indicates circumstances of a corresponding one of the plurality of mobile objects; a risk value calculator that calculates, for each of the plurality of items of anomaly data, a risk value that indicates a risk of an anomaly based on circumstance data about a corresponding mobile object; a priority determiner that determines a priority of each task to address an anomaly indicated by each of the plurality of items of anomaly data, based on the risk value of the anomaly data; an outputter that provides an output based on a result of the determination; and a circumstance change notification manager that determines whether or not each of the plurality of items of anomaly data is circumstance change notification target data that requests a corresponding mobile object to send circumstance data after change when circumstances have changed, wherein the circumstance change notification manager requests a mobile object corresponding to anomaly data determined to be the circumstance change notification target data to send circumstance data after change when circumstances have changed, when circumstance data after change is obtained, the risk value calculator recalculates the risk value of the anomaly data about the corresponding mobile object based on the circumstance data after change, and the priority determiner redetermines the priority of a task to address an anomaly indicated by the anomaly data about the corresponding mobile object based on the recalculated risk value.

2 . The priority determination system according to claim 1 , wherein
the circumstance change notification manager determines a particular type of anomaly data among the plurality of items of anomaly data to be the circumstance change notification target data.

3 . The priority determination system according to claim 2 , wherein
the circumstance change notification manager determines a circumstance item corresponding to the particular type of the anomaly data, and requests a mobile object corresponding to the anomaly data determined to be the circumstance change notification target data to send circumstance data after change when circumstances relating to the item have changed.

4 . The priority determination system according to claim 2 , wherein
when an anomaly indicated by the particular type of the anomaly data is addressed, the circumstance change notification manager causes the mobile object corresponding to the anomaly data determined to be the circumstance change notification target data to stop sending circumstance data after change.

5 . The priority determination system according to claim 1 , wherein
each of the plurality of items of circumstance data includes at least one item of information among type information indicating a type of the mobile object, position information indicating a position of the mobile object, traffic information about a site corresponding to the position information, traveling state information indicating a traveling state of the mobile object, driving assistance state information indicating a driving assistance state of the mobile object, and charge and discharge state information indicating a charge and discharge state of the mobile object.

6 . The priority determination system according to claim 1 , wherein
the risk value is a value obtained by correcting a base risk value determined according to a type of an anomaly with use of circumstance data about a corresponding mobile object.

7 . The priority determination system according to claim 1 , wherein
the priority of each task is determined based on the risk value of each of the plurality of items of anomaly data and a predetermined index value of the task.

8 . The priority determination system according to claim 7 , wherein
the predetermined index value of each task is at least one of a percentage of decrease of the risk by execution of the task and a time required to execute the task.

9 . The priority determination system according to claim 1 , wherein
the priority determiner performs the determination regularly, each time a task is executed, each time an anomaly is detected, or each time the risk value is calculated.

10 . A priority determination method comprising:
obtaining a plurality of items of anomaly data each of which indicates an anomaly of a corresponding one of a plurality of mobile objects; obtaining a plurality of items of circumstance data each of which indicates circumstances of a corresponding one of the plurality of mobile objects; calculating, for each of the plurality of items of anomaly data, a risk value that indicates a risk of an anomaly based on circumstance data about a corresponding mobile object; determining a priority of each task to address an anomaly indicated by each of the plurality of items of anomaly data, based on the risk value of the anomaly data; providing an output based on a result of the determination; and determining whether or not each of the plurality of items of anomaly data is circumstance change notification target data that requests a corresponding mobile object to send circumstance data after change when circumstances have changed; requesting a mobile object corresponding to anomaly data determined to be the circumstance change notification target data to send circumstance data after change when circumstances have changed; when circumstance data after change is obtained, recalculating the risk value of the anomaly data about the corresponding mobile object based on the circumstance data after change; and redetermining the priority of a task to address an anomaly indicated by the anomaly data about the corresponding mobile object based on the recalculated risk value.
