In a case where a failure has occurred in a vehicle, information that facilitates an analysis of the failure is acquired.In a case of receiving failure occurrence information transmitted from an in-vehicle device 12a or an on-road sensor device 12b, a server 14 transmits a request signal requesting transmission of related information to a device different from the in-vehicle device 12a or the on-road sensor device 12b that has transmitted the failure occurrence information. Then, the server 14 acquires each piece of the related information transmitted from the in-vehicle device 12a or the on-road sensor device 12b that has received the request signal.
