Abstract
A design method for a vehicle control system includes constructing a daisy chain trunk network by a central processing unit and a plurality of zone ECUs, calculating a first activation time from when a network is sequentially activated from a predetermined zone ECU to when the central processing unit is activated, calculating a second activation time from when a network is sequentially activated from the central processing unit to when the zone ECU 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 in a manner that a total time of the first activation time and the second activation time is less than a predetermined delay time.
