Research on Fault Tolerant Control Method of Automotive Electromechanical Brake Failure
摘要
Abstract
The failure of automotive electromechanical brake will produce many signals,which are easy to be lost in the transmission process,which will reduce the reliability of automobile electronic brake and affect the safety of automobile driving.Therefore,a fault-tolerant control method for automobile electro-mechanical brake failure is proposed.Based on the control principle of automotive electromechanical brake,a failure behavior detection model is constructed by using support vector machine(SVM).The failure be-havior of automotive electromechanical brake is effectively detected through failure prediction and failure i-dentification;an adaptive brake failure fault-tolerant control model is designed.By blocking and isolating the sensor signals that lead to brake failure,the estimated signals are used to replace the sensor signals that lead to brake failure to complete the failure fault-tolerant control of automotive electronic brakes.The ex-perimental results show that this method can realize the fault-tolerant control of automotive electrome-chanical brake failure,and the control effect is good.It can effectively improve the reliability of automotive braking.关键词
