Abstract
In a vehicular control system, when in the engine ECU, ATECU or brake ECU there occurs important information which requires an urgent response by any of the other ECUs, the important information is transmitted directly to the corresponding ECU through an important information communication line L1 without going through a manager ECU 10. Therefore, a controller in the ECU receives the important information and immediately controls the corresponding component based on the important information.
Claims24
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.

- 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 having an important information transmitting means which determines whether an urgent control for any remaining component control units is necessary based on operational conditions of the components, wherein 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;
- the control means thereof controls the component based on the important information when the component control unit requiring urgent control receives the important information;
- and
- wherein the manager control unit comprises:
- an entire vehicle operation determining unit which determines an operation guide for a whole of a vehicle based on operational information on components received from the component control units through the communication line;
- an operation guide determining means which determines operation guides for the components based on the operation guide for the whole of the vehicle determined by the entire vehicle operation determining means;
- a general information transmitting means which transmits the operation guides determined by the operation guide determining means to the corresponding component control unit through the communication line;
- and
- a second important information transmitting means which transmits the important information to a corresponding component control unit without going through the operation guide determining means when the operation guide for the whole of the vehicle determined by the entire vehicle operation determining means corresponds to the important information.
