Abstract

In an information processing system of the present disclosure, each of a plurality of ECUs registers information indicating presence or absence of an actual alarm for an item under control of the ECU, among a plurality of items in the first alarm list having a common format, and uniformly registers information indicating absence of an alarm for an item that is not under the control of the ECU. Each of the plurality of ECUs transmits the first alarm list in which registration is completed to a communication terminal. The communication terminal aggregates the number of alarms registered in a plurality of the first alarm lists received from the plurality of ECUs for each item, and aggregates the number of alarms registered in the plurality of the first alarm lists.

Dependent claims

An information processing system comprising:

a plurality of electronic control units (ECUs) mounted on a vehicle;
and
a communication terminal mounted on the vehicle, wherein:
each of the plurality of ECUs executes
acquiring a first alarm list in a template state, the first alarm list having a format common to the plurality of ECUs and including a plurality of items for registering presence or absence of an alarm regarding devices mounted on the vehicle by type of alarm,
registering information indicating presence or absence of an actual alarm, for an item under control of an ECU, among the plurality of items in the acquired first alarm list,
uniformly registering information indicating absence of an alarm, for an item that is not under the control of the ECU, among the plurality of items in the acquired first alarm list, and
transmitting the first alarm list in which registration of the information indicating the presence or absence of an alarm is completed, to the communication terminal;
and
the communication terminal executes
aggregating the number of alarms registered in a plurality of the first alarm lists received from the plurality of ECUs, for each of the items included in the first alarm list, and
