Abstract

The invention provides a method for controlling an air inlet system of an engine by a combined pulse spectrum, belonging to the vehicle engine control field, comprising a basic air inlet pulse spectrum parameter and a dynamic air inlet pulse spectrum parameter, wherein, the basic air inlet pulse spectrum parameter is standardized by a jack horse or optimized and standardized by the jack horse anda road parameter, the dynamic air inlet pulse spectrum parameter is generated by the self-standardization of the self-study on line of a control system and the self-optimization, the basic air inlet pulse spectrum parameter and the dynamic air inlet pulse spectrum parameter form a combined pulse spectrum parameter, and the adaptively control of the air inlet system of the gasoline engine is controlled by the control system according to a control strategy. The combined pulse spectrum control way synthesized by the self-adapting study method is adopted; therefore, the influence of the change ina controlled system and the unknown change on the engine is corrected, thereby improving the control accuracy of the open-loop control and increasing the speed and improving the timeliness of the control.

Description

technical field [0001] The invention relates to a method for controlling an engine intake system by combining maps, belonging to the field of automobile gasoline engine control. Background technique [0002] The control of gasoline engines for vehicles is divided into fuel injection control, ignition control, intake control, emission control and other auxiliary control systems; the fuel injection and intake air are related to determine the air-fuel ratio control, and the ignition control is the ignition advance angle and ignition closure rate. control, the EGR rate is applied for emission control. [0003] During the control process, the control unit checks the basic control map according to the basic control conditions, and corrects and outputs the basic control map according to the engine state conditions reflected by each sensor, and controls each actuator to control the target. Control is divided into open-loop control and closed-loop control. [0004] The air intake c...
