VEHICLE CONTROL SYSTEM

A vehicle control system includes a central ECU (10) configured to generate control signals for devices, and relay devices each disposed in a communication path between the central ECU (10) and a corresponding device among the devices. The relay devices include a specific relay device configured to output a control signal to a specific selective device not related to driving control, braking control, and steering control of a vehicle. The specific relay device includes a sub-control unit capable of controlling the specific selective device, based on an output of at least one sensor (100). In response to a central control abnormality that is an abnormality related to a control signal from the central ECU (10), the specific relay device controls, with the sub-control unit, the specific selective device coupled to the specific relay device.
