PROBLEM TO BE SOLVED: To provide a technology capable of performing computation on the basis of received data after the received data is checked to see if it is data received after a data change request is issued.SOLUTION: First, the merge ECU 4 receives individual data items for integration, which are computed by individual ECUs 2 and 3 that are included in a vehicle control system 1 and connected to be able to communicate data over a communication line 6, over the communication line 6, from individual ECUs 2 and 3, integrates the received individual data items for integration and individual data for integration which the merge ECU 4 has computed, and calculates first integrated data. When a trigger event that requests clear of the individual data items for integration is received from a trigger ECU 5, calculation of the first integrated data is inhibited. If a predefined modification completion condition signifying that the individual data items for integration received from the individual ECUs 2 and 3 have been modified based on the trigger event is established, inhibition of calculation of the first integrated data is lifted. |
