The use of electronics, intelligent sensors/actuators and microprocessor-based control technology enables online real-time fault detection and diagnosis (FDD) of automobiles. In this paper, a FDD method for electronic throttle system is proposed. The proposed FDD method is based on parameter estimation in closed-loop and a nonlinear model of the electronic throttle system. The nonlinear mathematical model of the electronic throttle system is identified in closed-loop, and then the parameter estimation technique is applied to the closed-loop nonlinear system model for the detection and isolation of faults. The simulation results are presented to investigate the performance and effectiveness of the proposed method.
