Abstract: After the air pressure of the tire of the vehicle has decreased to a predetermined abnormal value, the system management server determines that the vehicle has returned to a normal value without performing a tire replacement operation or a tire repair operation (for example, there is a driver that continuously drives the vehicle by replenishing air without performing a tire replacement even if the tire is punctured), and transmits abnormality notification information to the administrator terminal device. Thus, the warning information is provided to the current driver of the vehicle by the operation of the administrator terminal device by the administrator.
