Abstract
An integrated control for a machine such as an engine installed in a vehicle or vessel is conducted by the steps of: determining the characteristics of a user and/or using conditions; and changing characteristics of a control unit of a machine in accordance with the determined characteristics. Normally, the control unit includes: a reflection hierarchy for outputting a base value; a learning hierarchy for learning and operation; and an evolutionary-adaptation hierarchy for selecting the most adaptable module. The machine is “trained” to suit the characteristics of the user and/or the using conditions.
Claims18
A method for controlling a machine manipulated by a user, wherein operation of the machine is controlled by a control unit, said method comprising the steps of:
- (I) determining, on a real-time basis, indicia indicating manipulation patterns of the user or operating conditions of the machine;
- and (II) changing, on a real-time basis, characteristics of the control unit in accordance with the determined indicia,
- wherein said control unit outputs a base value to control the machine, and wherein the changing step comprises the steps of:
- (i) creating multiple control modules, used in the control unit, for representing at least one factor to be controlled;
- (ii) selecting at least one control module most adaptable for a current operational state based on the determined indicia;
- (iii) learning information from said at least one control module;
- (iv) compensating for the base value based on the result of the selection and the learning;
- and
- (v) controlling the machine using the output compensated for.
