During the past two decades, the automotive industry has been required to develop on-board health monitoring capabilities to meet legislated diagnostic requirements for engine management systems. Real-time diagnostics are presented which monitor the performance of an ETC (Electronic Throttle Control) system to detect and identify a suite of anomalies. The ETC system regulates the throttle plate angle using a DC (Direct Current) servo-motor to adjust the inlet airflow rate. The servo-motor is controlled by the applied armature voltage. The driver's commands and the throttle position feedback signal are processed by the ETC controller to regulate the servo-motor voltage. The ETC system is modeled and a parity diagnostic strategy is applied to detect the presence of faults. The specific nature of the fault is isolated using a parametric estimation methodology. Representative numerical results are presented and discussed to demonstrate the operational performance of the ETC System and health monitoring algorithms.
