Method for combined pulse spectrum controlling engine electronic air throttle

Abstract

The invention provides a method for controlling an electronic throttle control (ETC) of an engine by a combined pulse spectrum, belonging to the vehicle gasoline engine control field, comprising a basic throttle opening pulse spectrum parameter and a dynamic throttle opening pulse spectrum parameter, wherein, the basic pulse throttle opening spectrum parameter is standardized by a jack horse or optimized and standardized by the jack horse and a road parameter, the dynamic throttle opening 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 throttle opening pulse spectrum parameter and the dynamic throttle opening pulse spectrum parameter form a combined pulse spectrum parameter, and the adaptively control of the opening of the ETC of the gasoline engine is controlled by the control system according to a throttle opening control strategy. The combined pulse spectrum control way synthesized by the self-adapting study method is adopted; therefore, the influence of the change in a 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

Method of Controlling Electronic Throttle Valve of Engine by Combining Map technical field The invention relates to a method for controlling an electronic throttle valve of an engine by combining a map, belonging to the field of automobile gasoline engine control. Background technique During the engine control process, the control unit checks the control map parameters according to the basic control conditions, and corrects and outputs the control map parameters 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. Most of the currently used throttle control systems are controlled by mechanical connections, but more and more electronic throttles are being used to replace mechanical control methods; mechanical throttles use cables to transmit the displacement of the accelerator pedal to The throttle is converted into the opening of the throttle...
