Abstract
In a vehicle control system which requires a plurality of ECUs (electronic control units) to control in real time states of the vehicle using time-dependent data transmitted and received among the ECUs. The time-dependent data reflecting the vehicle states is detected or produced. A transmitting ECU, one of the plural ECUs, transmits the time-dependent data with a degree of newness thereof to a receiving ECU, another one of the plural ECUs, which takes part in the real-time control. The receiving ECU determines whether or not the time-dependent data has expired for the real-time control based on the degree of newness of the time-dependent data and performs processing with the time-dependent data based on determined results of the expiration, the processing having the time-dependent data adapted to the real-time control. Thus the real-time control can be performed based on only the adaptive time-dependent data to the real-time control.
