A vehicle integrated control device that can request torque having an appropriate magnitude and change speed to be given to an engine control unit from a drive system manager. A first maximum torque and a second maximum torque are presented to a drive system manager from an engine control unit. The drive system manager refers to the first maximum torque and the second maximum torque which are presented, and determines a request torque to be given to the engine control unit. The first maximum torque is a maximum torque that can be realized when only an operation amount of a throttle is actively changed without actively changing an operation amount of a wastegate valve. The second maximum torque is a maximum torque that can be realized when both the operation amount of the throttle and the operation amount of the wastegate valve are actively changed.
