Abstract: In various embodiments, methods, systems, and vehicle apparatuses are provided. In one exemplary embodiment, a method is provided that includes obtaining a set of inputs, by a processor, pertaining to one or more features that are used to predict the purge flow of a purge canister system of an intake system of a vehicle; obtaining data, by the processor, from sensors about the vehicle's intake system for use by a neural network to enable the processor to classify the set of inputs including the one or more features for purge flow control for use in predicting a presence of purge content in the vehicle's intake system; and obtaining, by the processor, an output from the neural network wherein the output is configured as a binary or continuous output to instruct a vehicle controller to execute an action to fueling control by letting fueling controller choose different gain sets and adaption strategy based on the binary output flag in a case of the binary-output model, or apply an adjustment factor to fueling command in case of a continuous model.

Abstract: A system operates to bypass one or more exhaust purifying devices during deceleration fuel cut-off (DFCO) events in order to avoid hydrocarbon purging. The system includes an internal combustion engine and exhaust purifying system including a first purifying device and a second purifying device. An exhaust gas sensor monitors an exhaust gas feedstream. A diverter valve is disposed to manage the exhaust gas feedstream and fluidly coupled to an exhaust diversion pipe. A controller detects operation of the engine in a DFCO state and monitors the exhaust gas feedstream via the exhaust sensor. The diverter valve is controlled to divert the exhaust gas feedstream away from at least one of the first and second purifying devices during the DFCO event when the exhaust gas feedstream has an air/fuel ratio that is greater than a threshold air/fuel ratio.

Abstract: Methods and systems for predicting a vehicle stop event and/or operating a purge pump for a vehicle are disclosed. An example method includes providing a fuel vapor canister in fluid communication with a fuel tank of the vehicle, the fuel vapor canister configured to absorb fuel vapors from the fuel tank, and placing a purge pump in fluid communication with the fuel vapor canister, with the purge pump being configured to pump an external airflow into the canister. Some methods and systems may be directed to predicting a vehicle stop while the vehicle is moving based upon at least a model of vehicle speed, and initiating a vehicle response based upon the prediction. In some examples, a vehicle response includes reducing ambient noise emitted by the purge pump.
