Engine control method and device based on artificial intelligence

Abstract

The invention provides an engine control method and device based on artificial intelligence. The engine control method comprises the steps of obtaining information of an engine, wherein the information of the engine comprises information collected by each sensor and control information of each control switch; judging the current work condition according to the information of the engine; obtainingsensor information, stored in a self-learning database, under the current work condition; calculating the control instruction under the current work condition according to the sensor information, stored in the self-learning database, under the current work condition; sending the control instruction to a corresponding actuator so as to control operation of the engine; wherein the self-learning database is obtained by deep learning and training based on the sensor information under various work conditions and corresponding control instructions, and the control instructions are obtained by calculating based on the sensor information. By the adoption of the engine control method and device based on artificial intelligence, under the condition of meeting emission requirements and power requirements, the engine can keep the best work state under various work conditions.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of engine control, in particular to an artificial intelligence-based engine control method and device. Background technique [0002] The engine electronic control system controls the engine ignition, fuel injection, air-fuel ratio, and exhaust emissions to make the engine work in the best state, so as to achieve the purpose of good vehicle performance, energy saving, and reduced exhaust emissions. [0003] The control mode of the traditional engine control system has gone through open-loop control to closed-loop control. Closed-loop control is based on the open-loop control of the control system, and determines the increase or decrease of the output control amount according to the feedback signal of the actually detected control result. The system not only has a positive effect but also a feedback effect between the controller and the controlled object, that is, the control result o...

Problems solved by technology

[0004] However, in the increasingly stringent regulations of automobile emission standards, the traditional open-loop to closed-loop methods are difficult to meet the highest performance and emission regulations of the engine

For example, with the improvement of emission and fuel consumption standards, the calibration of engine EFI system requires more and more variable parameters, which not only requires huge calibration equipment, but also more and more expensive development costs. At the same time, after the calibration is completed, it is fixed. Even if the vehicle can meet the national emission regulations and fuel consumption requirements at that time, it is difficult to meet the latest fuel consumption and emission requirements
