Abstract
In an on-vehicle system, the gateway is duplexed, and a countermeasure table is included. The countermeasure table defines a failure phenomenon occurring in communication, an identification method for identifying a factor on whether the failure phenomenon is caused by a failure of the gateway or caused by a security attack on the gateway, and a corresponding countermeasure method. When it is detected that a failure phenomenon has occurred is communication through the gateway, the on-vehicle system determines a factor of the detected failure phenomenon based on the identification method defined in the countermeasure table, and makes countermeasures in accordance with the corresponding countermeasure method.
