ABSTRACT:
Apparatus and method for estimating an attribute associated with a mobile machine. The machine has an engine and a powertrain. The powertrain includes a torque converter coupled to the engine. The apparatus and method sense a plurality of parameters of the machine and responsively produce a plurality of respective parameter signals and calculating an estimated value of the attribute as a function of the parameter signals using a computer based model. The apparatus and method further calculates first and second estimated values of a torque converter input torque, compares the first and second torque converter input torque estimate signals and responsively calibrates the computer based model.
