1. A vehicle control system comprising:
a plurality of zone ECUs each of which is disposed in each predetermined zone of a vehicle; and
a central processing unit that integrally controls the zone ECUs, wherein
the zone ECUs include a plurality of first zone ECUs that each output a blinking timing signal for blinking a corresponding one of blinkers installed in the vehicle on a basis of a blinking control signal received from the central processing unit,
the central processing unit and each of the first zone ECUs are connected by a time synchronization network, whereas each of the first zone ECUs and the corresponding one of the blinkers are connected by a time asynchronous network,
the first zone ECUs are configured to be connected to each other-via a local network, share blinking timing information of the blinkers with one another via the local network, and adjust the blinking timing signal on a basis of the blinking timing information that is shared, and
each of the first zone ECUs is configured in a manner that in a case where blinking timing of another first zone ECU is earlier than its own blinking timing, a turn-off start time during a blinking period is made to match a turn-off start time of the another first zone ECU.
