More Information
Summary:A system for diagnosing operation of a control system of at least one automobile driving parameter using a dynamic model, which includes a mechanism that stores on a non-volatile memory the input and output data of the system during the operation, adapted to store the data at a sampling frequency lower than the system sampling frequency, and including a dynamic model that can be stimulated by the stored input data to determine the reconstituted output data, and a comparison mechanism that compares the reconstituted output data with the stored output data for consistency diagnosis.
