Patent ID: 7499782

Claim:
A system for controlling, in real times, states of a vehicle, in which the real-time control is performed based on time-dependent data transmitted and received among a plurality of ECUs (electronic control units) dedicated to the control of the states of the vehicle, the system comprising: a first ECU, which is one of the ECUs, comprises transmitting means for transmitting the time-dependent data and addition means for adding information indicative of a degree of newness of the time-dependent data obtained in the first ECU to the time-dependent data to be transmitted by the transmitting means; and a second ECU, which is another of the ECUs, which comprises: a determination unit determining 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 to be received from the first ECU; and a processing unit performing processing with the time-dependent data based on results of the expiration determined by the determination unit, the processing having the time-dependent data adapted to the real-time control.
