Intelligent Control, Correction, and Adaptability of Output Parameters of Vehicles’ Intake System

Abstract

© 2020, Springer Nature Switzerland AG. Today, the modern motor industry is developing in the direction of significant intellectualization, automation, and robotics at the system operation. It provides for the creation of a comprehensive system of system control algorithms. However, when the technical condition of individual electronic components varies, the control algorithms can significantly change. Thus, correction and adaptation of the operation algorithms to the changing technical condition of the vehicle systems is necessary for a further qualitative object operation. Thus, failures of mass airflow sensors and idle air control valves comprise 14 and 12%, respectively, of the number of failures of all the elements of the microprocessor-based engine control system. A failure of these components leads to a serious change in fuel consumption and exhaust toxicity. We developed an experimental research procedure to elaborate the modes of correction and adaptation to the changing technical condition of these elements of the car electronics. It lies in the formation of stress test actions consisting in the cutout of the nth number of cylinders and individual operating cycles and subsequent loading of the kth number of cylinders. As a result of experimental studies, we built diagrams of the dependencies of the said control parameters on the cylinder load. We analyzed the diagrams, based on which we determined the inflection points corresponding to the prelimit and limit change in the technical condition of the mass airflow sensors and idle air control valves. The developed method of stress test actions allows us to avoid purchasing expensive load banks.
