1. An electronic control unit incorporated as one of a plurality of electronic controllers composing a system for controlling in-vehicle devices on a distributed and mutually-synchronized control manner in a vehicle, the plurality of electronic control units being communicably connected with each other via an in-vehicle network so as to communicate information including time-dependent data among the electronic control units, the time-dependent data being acquired in time series relating to the vehicle, the electronic control unit comprising:

  • a control member performing the control on the basis of time-dependent data;

    an elapsed-time calculation component configured to calculate an elapsed time elapsing from acquisition of the time-dependent data; and

    a validity determination component configured to use the calculated elapsed time to determine whether or not the time-dependent data is valid or not for the control in terms of freshness of the time-dependent data.
