ILLEGALITY DETECTION ELECTRONIC CONTROL UNIT, CAR ONBOARD NETWORK SYSTEM, AND ILLEGALITY DETECTION METHOD

摘要

An anomaly detection electronic control unit, that performs anomaly detection processing and that is connected to a bus which a plurality of electronic control units use for communication to communicate following a CAN (Controller Area Network) protocol, includes an anomaly detection processing requesting unit that decides an anomaly detection processing timing based on an ID of a data frame acquired from the bus, and an anomaly detection processing unit that performs anomaly detection processing regarding the data frame at the anomaly detection processing timing decided by the anomaly detection processing requesting unit.
