Learning and control apparatus for electronically controlled internal combustion engine
This patent describes a learning and control apparatus for an electronically controlled internal combustion engine, comprising: means for detecting an actual value of a parameter of an object within the engine to provide a detected object parameter, the parameter to be controlled in accordance with a control value; means for detecting an engine driving state; basic control quantity setting means for setting a basic control quality corresponding to a desired control value of the object; memory means for storing lattice axes driving the engine driving state detected by the detecting means into a plurality of regions in accordance with a parameter of the engine driving state and storing correction quantities for correcting the basic control quantity for each respective region defined by lattice axes; learning correction quantity retrieving means for retrieving the stored correction quantity of each corresponding region from the memory means based on the detected engine driving state of the engine; feedback correction quantity setting means for comparing the desired control value with the detected actual value of the detected object parameter and setting a feedback correction quantity by increasing or decreasing a feedback correction quantity by a predetermined quantity so that the actual value is brought close to the desired control value.
