Abstract

The communication network system sends an offer message to the first communication bus by the providing-side electronic control unit when the network is updated. The electronic control unit selects whether or not to receive a service message provided by the providing-side electronic control unit by confirming the offer message. The receiving-side electronic control unit that has selected to receive the service message changes the settings to receive the service message. The receiving-side electronic control unit sends a subscription message to the first communication bus. Upon receiving the subscription message, the providing-side electronic control unit starts providing the service by the service message.
