A METHOD FOR SUBDIVIDING A STUDYING DRIVE AREA OF FUEL CONTROL METHOD

摘要

The method of subdividing the learning operation area of the fuel control system is to improve the degree of learning control by subdividing the engine speed and the engine load according to the acceleration and deceleration conditions, and detecting the engine speed and the engine load at a predetermined time interval. ; Sequentially storing engine speed and engine load values up to a certain time in the past based on the present; Calculating a change amount of the engine speed and a change amount of the engine load by calculating a difference between the engine speed and the engine load in the current operation region and the engine speed and the engine load before a certain time in the past; Dividing the calculated change amount of the engine speed and the change amount of the engine load into acceleration / deceleration states and subdividing the regions respectively; The main purpose is to determine the final learning operation region according to the change amount of the engine speed and the change of the engine load, which are respectively subdivided according to the acceleration and deceleration conditions, and the current engine speed and the current engine load value.
