Abstract


In recent years, with the automotive industry increasingly booming , the the car overall structure , particularly technical performance in continuous improvement upgrade. Scientific and effective detection method instead of behind the engine diagnostic technology to ensure automotive safety , reliable operation of current technology research in the field of hot issues . Automotive engine fault diagnosis system , the importance of the status of the sensor is self - evident that the great significance of its data collection and fault diagnosis and fault-tolerant technology to improve the overall performance of the automobile engine control systems . In summary , this paper carried out a comprehensive study of automotive engine fault diagnosis and fault-tolerant control technology . This paper describes the car engine multi- sensor system fault diagnosis and fault-tolerant control structure , and select one of the intake manifold pressure sensor characteristics analysis and works ; then integrated fault diagnosis and fault-tolerant control technology research base , the paper carried out in-depth study of couplet banca Kalman filter algorithm and artificial neural network algorithm , Contact the practical feasibility of its theoretical superiority of these two algorithms , and apply them to the automotive engine intake pressure sensor fault diagnosis overall framework design of fault-tolerant control system structure design ; Finally, simulation experiments . In this study, the simulation experiment used the intake manifold pressure sensor piezoresistive most models are commonly used for the study , the precision parameter design and precision algorithm control , and ultimately achieve the purpose of signal to restore remodeling and correction processing , to achieve the target , then the engine can be run in a more efficient and reliable state , to ensure the stability of the overall engine system .
