Abstract: During normal engine operation, a temporary determination mode is executed in which whether or not there is an air-fuel ratio variation among cylinders is determined on the basis of distortion in output waveform of an LAF sensor, concurrently with determination of deterioration of a three-way catalyst, under a control condition of normal learning sensitivity of the learned value of a stoichiometry correction factor. If it is determined in the temporary determination mode that there is an air-fuel ratio variation, the determination mode is switched to a main determination mode and the learning sensitivity of the learned value of the stoichiometry correction factor is set to the sensitive side to determine whether or not there is an air-fuel ratio variation among the cylinders with higher reliability on the basis of the learned value of the stoichiometry correction factor (=the value of an enrichment process counter C2) which increases rapidly due to the air-fuel ratio variation among the cylinders.

Abstract: A method of estimating soot loading in a diesel particulate filter (DPF) in a vehicle exhaust system includes estimating an engine-out soot rate using a first neural network that has a first set of vehicle operating conditions as inputs. The method further includes estimating DPF soot loading using a second neural network that has the estimated engine-out soot rate from the first neural network and a second set of vehicle operating conditions as inputs. Estimating the engine-out soot rate and estimating the DPF soot loading are performed by an electronic controller that executes the first and the second neural networks. The method also provides for training the first and second neural networks both offline (for initial settings of the neural networks in the vehicle), and online (when the vehicle is being used by a vehicle operator). An exhaust system has a controller that implements the method.
