ABSTRACT:
A method is provided, for use in controlling an apparatus or for use by a controller of apparatus, for estimating a single torque variable utilizing multiple models. In one embodiment, the apparatus is a vehicle. The method includes the steps of sensing operating parameters to obtain associated operating signals and obtaining estimates of the torque variable from at least two independent models. Each model generates a torque estimate signal based on the operating signals. The method also includes the steps of weighting the individual torque estimate signals according to a predefined accuracy of the associated torque model, to obtain a plurality of weighted individual torque estimate signals, and generating a final torque estimate signal based on the weighted individual torque estimate signals. Once the final torque estimate signal is obtained, the apparatus can be controlled based on the final torque estimate signal.
