PROBLEM TO BE SOLVED: To achieve shortening of a wire length and simplification of wiring in a vehicle control system.SOLUTION: A vehicle control system includes: a plurality of function ECUs (Electronic Control Unit) which are arranged separately in a plurality of regions of a vehicle and classified into a plurality of groups by functions of function parts to be controlled; a plurality of relay ECUs which are arranged in the respective regions; a first network which connects the plurality of relay ECUs with each other; and second networks which are arranged in the respective regions and connect the function ECU and the relay ECU in each region. Each function ECU, when communicating with the function ECU which is classified into the same group as said function ECU arranged in a region different from the region where said function ECU is arranged, performs transmission and reception of data via the second network and the relay ECU in the region where said function ECU is arranged, the first network, and the relay ECU and the second network in the region where the function ECU to be communicated with is arranged. |
