The electronic control units include a master unit and a node apparatus composed of electronic control units other than master unit. In the node apparatus, a node time locally used as a reference time by the node apparatus is produced, and a system reference time is received from the master unit via the network. A node time rate, which is a rate of change of the node time per predetermined time period, is calculated based on changes in the node time. A reference time rate, which is a rate of change of the system reference time per the predetermined time period, is also calculated based on changes in the received system reference. The node time production is controlled such that the node time reduces a difference between the node and reference time rates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Node apparatus mounted in vehicle and in-vehicle network system","description":"An in-vehicle network system includes plural electronic control units data-communicably connected via a network.
