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.

A server device includes a communication unit and a control unit that sends and receives information to and from another device via the communication unit. The control unit sends, to a terminal device, information on a comfort level in a vehicle cabin of a shared vehicle that is determined based on a detection result of detecting an effect of a passenger on a vehicle body or equipment of the shared vehicle to present the information to another passenger before boarding the shared vehicle.
