COMMUNICATION NETWORK SYSTEM AND METHOD FOR CHANGING COMMUNICATION SETTINGS DURING NETWORK UPDATE

Abstract

The communication network system sends a request message to the first communication bus by the receiving-side electronic control unit when the network is updated. When the electronic control unit receives a request message including a service identifier corresponding to a service that can be provided by the electronic control unit, the electronic control unit transmits a response message to the first communication bus as the providing-side electronic control unit. Thereafter, the providing-side electronic control unit starts providing the service by transmitting a service message to the first communication bus. The receiving-side electronic control unit that receives the response message changes the setting to receive the service message.
