TORQUE ESTIMATOR FOR ENGINE RPM AND TORQUE CONTROL

摘要

An engine toque estimator according to the invention includes a vehicle data bus that provides a plurality of engine operating inputs including at least one of engine RPM, spark and a dilution estimate. A steady state torque estimator communicates with the vehicle data bus and generates a steady state engine torque signal. A measurement model communicates with the vehicle data bus and compensates for errors associated with engine-to-engine variation. A dynamic torque estimator communicates with at least one of the vehicle data bus, the measurement model, and the steady state torque estimator and generates an actual torque signal.
