Abstract:
An integrated vehicle control system comprising:a plurality of component control units which respectively control a plurality of components of a vehicle according to preset control programs; a manager control unit which issues commands of operation guides to the plurality of component control units, the operation guides being for the components controlled by the component control units; and a communication line which connects the manager control unit and the component control units and connects the component control units together; wherein each of the plurality of component control units includes a manipulated variable calculating means which calculates a manipulated variable of components controlled by the component control unit, the calculating means being based on the operation guide received from the manager control unit through the communication line, each of the plurality of component control units including a control means which controls the components according to the manipulated variable calculated by the manipulated variable calculating means; at least one of the plurality of component control units has an important information transmitting means which determines whether an urgent control for any of remaining component control units is necessary based on operational conditions of the components, wherein the one of the plurality of component control units transmits important information directly to a component control unit that requires urgent control through the communication line; and the control means thereof controls the component based on the important information when the component control unit requiring urgent control receives the important information.
