Failure management system and failure management method

Abstract

A failure management device includes: an information collection unit configured to collect failure information which is information about a failure of devices or instruments loaded in a vehicle; a notification unit configured to output a failure notice notifying occurrence of the failure inside the vehicle; and an instruction unit configured to instruct the notification unit whether or not to output the failure notice when the failure of one of the devices or the instruments is found based on the failure information, and the instruction unit prohibits the notification unit from outputting the failure notice when the device or the instrument in which the failure is found is not involved in execution of an option function for which the execution is permitted, based on management information indicating whether or not the execution of the option function is permitted for each of the option functions in the vehicle.
