Development of Automotive Exhaust Emission Detection System Based on Fuzzy PID Adaptive Algorithm

Based on the theory of fuzzy PID control, a brand-new and efficient automobile exhaust emission detection system is successfully developed through constant speed, constant torque and constant power control. The system is designed with a signal conditioning circuit to achieve monitoring of automobile exhaust emissions. This paper elaborates the technical route of the development of the automobile exhaust emission detection system, introduces the detection methods, procedures and criteria for automobile exhaust emissions, analyzes the overall structure of the automobile exhaust emission detection system, discusses the design of the system, and carries out system tests and result analysis to improve the level of automobile exhaust emission detection.
