PROBLEM TO BE SOLVED: To enhance efficiency in development by flexibly and easily coping with increase of control modules, speedup, partial change of specification of the control module and increase of information communication quantity between control modules, caused by improvement of performance of a vehicle, with less labor and time for development. SOLUTION: In this vehicle control communication system 1 plural control function units such as ECI engine (engine control) are separated into an I/O processing function and an operation control function and the I/O processing function in every control function unit is constituted of each of I/O processing nodes 31a to 31c, 32a, 32b, 33a, 33b. The operation control function is constituted as one of operation control nodes 21 to 23 for each of vehicle control groups 11 to 13 formed by grouping related control function units, transmission and reception of information in each of the vehicle control groups 11 to 13 are performed via communication channels N11 to N13 and transmission and reception of information among the vehicle control groups 11 to 13 are performed via the communication channel N2.
