1. A vehicle control system mounted on a vehicle, the vehicle control system comprising:
an entry ECU that detects access to the vehicle from an outside of the vehicle and executes first authentication processing on the access which is detected;
a first communication bus to which the entry ECU is connected;
a door control ECU that controls locking and unlocking of a door of the vehicle;
a second communication bus to which the door control ECU is connected; and
a central ECU having a gateway function of managing signal transmission between the first communication bus and the second communication bus, wherein
the entry ECU transmits a first startup request, which instructs to start up the central ECU, to the central ECU before executing the first authentication processing when the access is detected, and
the central ECU transmits a second startup request, which instructs to start up the door control ECU, to the door control ECU in response to reception of the first startup request.
