VEHICLE CONTROL SYSTEM AND VEHICLE CONTROL SYSTEM DESIGN METHOD

A design method for a vehicle control system includes constructing a daisy chain trunk network by a central processing unit (10) and a plurality of zone ECUs (2), calculating a first activation time from when a network is sequentially activated from a predetermined zone ECU (2) to when the central processing unit (10) is activated, calculating a second activation time from when a network is sequentially activated from the central processing unit (10) to when the zone ECU (2) is activated, and determining a connection destination of an information acquisition unit and a connection destination of an in-vehicle device from the zone ECUs (2) in a manner that a total time of the first activation time and the second activation time is less than a predetermined delay time.
