The Method and Apparatus of Predicting MAF Sensor Information includes training multiple candidate Artificial Neural Network (ANN) architectures using training data, and then selecting an ANN architecture from the candidates using an automated ANN architecture selection algorithm and testing data. An intelligent engine intake MAF prediction or estimation system using the selected ANN architecture then provides an engine intake Mass Air Flow (MAF) output variable, which is used along with the output of a hot-wire type engine intake MAF sensor. The system is deployed into the engine controller. The training and testing sets of data include input variables from engine sensors and/or actuators that relate to engine intake MAF, and may be acquired by testing a target engine. Selecting the optimal ANN architecture may be based on Root Mean Squared Error (RMSE) analysis using the automated ANN architecture algorithm and the training set of data.

A system for conducting a rationality check of a transmission grade sensor includes a controller configured to calculate a change in elevation over time based on a change in barometric pressure. The controller calculates another change in elevation based on an average grade determined from a transmission grade sensor. The controller compares the second change in elevation to the first change in elevation and, if there is a significant discrepancy between them, calculates a grade correction factor. The controller then modifies the shift logic and/or shift schedule of the transmission based on the average grade from the transmission grade sensor and on the grade correction factor.

A system for operating a vehicle equipped with an automatic transmission and a vehicle road speed limiter (RSL) which is programmable to limit the maximum vehicle speed for a given transmission gear includes at least on controller. The at least one controller is operable, when the speed limiter (RSL) is active, to determine if the vehicle is operating in a shuttle shifting range based on the current status of preselected operating parameters. When the vehicle is operating in a shuttle shifting range, the at least one controller is operable to control transmission operation to prevent shifting under conditions where shifting would otherwise normally occur.
