Management system, management method, and storage medium

A management method used in a management system in which an autonomous driving assistance center periodically communicates with an autonomous vehicle, which is automatically driven, to manage a vehicle state of the autonomous vehicle, the method comprising:

• determining, when communication between the autonomous driving assistance center and the autonomous vehicle is disconnected, whether to continue autonomous traveling and whether to notify an assistant assisting the autonomous vehicle, based on communication situation information that indicates a situation of communication between the autonomous driving assistance center and the autonomous vehicle at each place, where the autonomous vehicle is allowed to travel, in a management target area of the management system, wherein
• determining whether to continue autonomous traveling and whether to notify an assistant assisting the autonomous vehicle further comprises deriving a vehicle side expected period, which is a period within which disconnected communication is expected to be restored, based on a traveling route of the autonomous vehicle and the communication situation information, and determines to continue the autonomous traveling if the derived vehicle side expected period is a predetermined period or less, and
• the autonomous traveling is stopped in response to determining that the derived vehicle side expected period is outside the predetermined period.

A non-transitory storage medium in which a management program used in a management system in which an autonomous driving assistance center periodically communicates with an autonomous vehicle, which is automatically driven, to manage a vehicle state of the autonomous vehicle is stored to cause a computer to execute processing, the processing comprising:

• determining, when communication between the autonomous driving assistance center and the autonomous vehicle is disconnected, whether to continue autonomous traveling and whether to notify an assistant assisting the autonomous vehicle, based on communication situation information that indicates a situation of communication between the autonomous driving assistance center and the autonomous vehicle at each place, where the autonomous vehicle is allowed to travel, in a management target area of the management system, wherein
• determining whether to continue autonomous traveling and whether to notify an assistant assisting the autonomous vehicle further comprises deriving a vehicle side expected period, which is a period within which disconnected communication is expected to be restored, based on a traveling route of the autonomous vehicle and the communication situation information, and determines to continue the autonomous traveling if the derived vehicle side expected period is a predetermined period or less, wherein
• the autonomous traveling is stopped in response to determining that the derived vehicle side expected period is outside the predetermined period.
