Patent number: 8495407Abstract: An in-vehicle network system includes plural electronic control units data-communicably connected via a network. 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.
