6 Claims

1. A system comprising:

a first control device mounted on a first mobility to be controlled and that controls the first mobility, the first mobility to encounter a condition at a first time;

a second control device mounted on a second mobility to be controlled and that controls the second mobility, the second mobility to encounter the condition at a second time after the first time; and

an external server that obtains the condition of the first mobility from the first control device,

wherein the first control device includes:

a first memory storing first instructions; and

a first processor configured to execute the first instructions to:

detect the condition of the first mobility at the first time;

perform a first determination to determine an abnormality of the first mobility based on the detected condition; and

in a case that the abnormality of the first mobility cannot be determined in the first determination, transmit to the external server the detected condition of the first mobility and position information indicating a position where the condition has been detected,

wherein the external server includes:

a second memory configured to store second instructions; and

a second processor configured to execute the second instructions to:

receive the condition of the first mobility and the position information from the first control device;

perform a second determination to determine the abnormality of the first mobility, based on the condition of the first mobility and the position information where the condition has been detected; and

transmit a result of the second determination to the first control device and to the second control device,

wherein the first processor in the control device is configured to execute the first instructions to further issue a warning to a first output device, based on the abnormality indicated in a result of the second determination,

wherein the second control device includes:

a third memory storing third instructions; and

a third processor configured to execute the third instructions to:

receive the result of the second determination from the external server, before the second time;

detect the condition of the second mobility at the second time;

perform a third determination to determine the abnormality of the second mobility based on the detected condition and based on the result of the second determination; and

issue a warning to a second output device based on the abnormality indicated in a result of the third determination,

wherein transmission of the result of the second determination from the external server to the second control device permits the second control device to detect the abnormality of the second mobility and suppresses transmission of the detected condition of the second mobility and position information of the second mobility from the second control device to the external server to detect the abnormality of the second mobility.
