description An increase in the number of signal lines of a control apparatus for controlling devices of an automobile can be prevented and safety of the automobile can be secured. An in-vehicle communication system includes an input DHM that obtains device data from an input device, a BCM that generates control data for controlling an output device based on a value of the device data, and an output DHM that controls the output device according to the control data. The input DHM is composed of duplexed input control blocks, duplexed input shared memories, and an input NW control block. The BCM is composed of a BCM_NW control block, duplexed BCM shared memories for different intended uses, and duplexed arithmetic blocks. The output DHM is composed of an output NW control block, duplexed output shared memories, duplexed output control blocks, and a matching circuit.
