    摘要: A fuel control system delivers fuel to an engine cylinder and compensates for lost fuel. The fuel control system comprises a fuel dynamics module that determines a fuel dynamics model that is indicative of fuel behavior. The fuel dynamic module determines an inverse of the fuel dynamics model, receives a fuel command, and generates an adjusted fuel command based on the fuel command and the inverse of the fuel dynamics model. A lost fuel compensation module receives the adjusted fuel command and generates a final fuel command based on the adjusted fuel command and a lost fuel factor. A control module controls fuel delivery according to the final fuel command.

    摘要: A vehicle system includes a throttle position sensor that generates a current throttle position signal (TPS), a MAF sensor that generates a current actual MAF signal, and a manifold absolute pressure (MAP) sensor that generates a current actual MAP signal. A controller determines a current estimated cylinder air flow (CAF) signal, determines a MAF transient signal and determines a MAP transient signal. The controller determines a predicted CAF signal into the engine based on the current estimated CAF signal, the current actual MAF signal, the current MAP signal, a current TPS signal, the MAF transient signal and the MAP transient signal.

    摘要: An inlet air dynamics (IAD) characterization control system for an internal combustion engine includes a first module that estimates a future firing event manifold absolute pressure (MAP) and a second module that determines a MAP cycle difference based on the future firing event MAP and a previous cycle MAP. A third module characterizes an IAD state based on the MAP cycle difference.

    摘要: An air dynamic steady state detection system for movement of a cam phaser of an internal combustion engine includes a cam position sensing device and a control module. The cam position sensing device generates a position signal based on a position of the cam phaser of the engine. The control module receives the position signal and applies first and second filters to the position signal to select either a transient or steady state condition. The control module also calculates an estimated air value based on the selection of the transient or steady state condition.
