Abstract
An integrated control system for a vehicle comprises a plurality of system device control units for controlling system devices in a vehicle, and a manager control unit for providing the system device control units with commands serving as operation directives of the system devices. A particular one of the system device control units has a hierarchical layer. If the predetermined operation should be carried out, the particular system device control unit issues a command to the particular system device as an independent operation directive for driving the particular system device to carry out the predetermined operation independently of an operation directive issued by the manager control unit.
Claims15
An integrated control system for a vehicle comprising:
- a plurality of system device control units for controlling operations carried out by a plurality of system devices employed in a vehicle in accordance with control programs set in advance;
- and
- a manager control unit for providing the system device control units with commands serving as operation directives of the system devices controlled by the system device control units,
- wherein at least a particular one of the system device control units has a hierarchical layer secession determination means for determining whether a particular system device controlled by the particular system device control unit has entered a predetermined operational state requiring that a predetermined operation taking precedence of execution of an operation directive issued by the manager control unit be carried out, and
- wherein, if the hierarchical layer secession determination means determines that the predetermined operation should be carried out, the particular system device control unit issues a command to the particular system device as an independent operation directive for driving the particular system device to carry out the predetermined operation independently of an operation directive issued by the manager control unit.

An integrated control system for a vehicle comprising:
- a plurality of system device control units for controlling operations carried out by a plurality of system devices employed in a vehicle in accordance with control programs set in advance;
- and
- a manager control unit for providing the system device control units with commands serving as operation directives of the system devices controlled by the system device control units,
- wherein the manager control unit has at least a vehicle whole operation determining means for determining an operation of the vehicle as a whole, and a system device integrated control unit for giving a command to any of the system device control units as an operation directive based on an operation directive issued by the vehicle whole operation determining means as a command,
- wherein the system device integrated control unit has a hierarchical layer secession determination means for determining whether a particular system device controlled by a particular one of the system device control units has entered a predetermined operational state requiring that a predetermined operation taking precedence of execution of an operation directive issued by the manager control unit be carried out, and
- wherein, if the hierarchical layer secession determination means determines that the particular system device has entered a predetermined operational state requiring that the predetermined operation be carried out, the system device integrated control unit issues a command to the particular system device control unit as an independent operation directive for driving the particular system device to carry out the predetermined operation and a command to each of the system device control units other than the particular system device control unit as an operation directive for driving the other system device control unit to carry out another predetermined operation conforming to the independent operation directive.

A method of providing integrated control of a vehicle, the method comprising:
- controlling operations performed by a plurality of system devices employed in a vehicle through a plurality of system device control units in accordance with control programs set in advance;
- and
- providing the system device control units with commands serving as operation directives of the system devices controlled by the system device control units from a manager control unit,
- wherein at least a particular one of the system device control units provides a hierarchical layer secession determination including determining whether a particular system device controlled by the particular system device control unit has entered a predetermined operational state requiring that a predetermined operation taking precedence of execution of an operation directive issued by the manager control unit be carried out, and
- wherein, if the hierarchical layer secession determination is made so that the predetermined operation should be carried out, the particular system device control unit issues a command to the particular system device as an independent operation directive for driving the particular system device to carry out the predetermined operation independently of an operation directive issued by the manager control unit.
