Failure management system and failure management method

A failure management system comprising

• a failure management device loaded in a vehicle and a management server provided outside the vehicle and communicably connected with the failure management device, wherein
• the 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 the vehicle, and
• a notification unit configured to output a failure notice notifying occurrence of the failure inside the vehicle,
• the management server includes
• a first 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,
• the notification unit performs an output operation of the failure notice according to an instruction from the first instruction unit, and
• the first 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.

A failure management method executed by a computer, the method comprising:

• a collection step of collecting failure information which is information about a failure of devices or instruments loaded in a vehicle;
• an instruction step of determining an instruction on whether or not to output a failure notice notifying occurrence of the failure when the failure of one of the devices or the instruments is found based on the failure information;
• and
• a notification step of outputting the failure notice inside the vehicle according to the instruction determined by the instruction step,
• wherein, in the instruction step, the instruction of prohibiting output of the failure notice is determined 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.
