  • Publication number: 20190178133
    Abstract: A method includes determining whether a urea refill event is detected, and clearing a quality accumulator value and clearing a latching abort command. The method includes determining whether urea fluid quality check abort conditions are met, and clearing the urea quality accumulator, latching the abort command, and exiting the reductant fluid quality check. In response to the abort conditions not being met, incrementing the urea quality accumulator according to an amount of urea being injected, and comparing the accumulated urea quantity to a low test threshold. The method includes, in response to the accumulated urea quantity being greater than the low test threshold, comparing the accumulated urea quantity to a high test threshold, and in response to the urea quantity being greater than the high test threshold, determining whether the a NOx exceedance is observed and clearing a urea quality error in response to the NOx exceedance not being observed.

  • Publication number: 20190168753
    Abstract: Systems and apparatuses include a controller structured to: receive information indicative of an operating condition of a vehicle subsystem, receive information indicative of an external static condition, and receive information indicative of an external dynamic condition. The system is further configured to predict a fuel cut event based on at least one of the operating condition of the vehicle subsystem, the external static condition, and the external dynamic condition. Responsive to predicting a fuel cut event, the controller is structured to modulate at least one of a torque or a speed of the engine based on the operating condition of the vehicle subsystem and at least one of the information indicative of the external static condition and the external dynamic condition.

  • Patent number: 10302034
    Abstract: One exemplary embodiment is a method of operating a system comprising an internal combustion engine system, and an exhaust aftertreatment system comprising an SCR catalyst, and an electronic control system. The method comprises operating the electronic control system to perform the acts of determining a predicted temperature value indicative of a predicted future temperature of the SCR catalyst, determining a temperature profile value using the predicted temperature value and a current temperature value indicative of a current temperature of the SCR catalyst, operating a controller to provide an output indicating a difference between the temperature profile value and a temperature target, determining a heat request using the output of the controller, filtering the heat request using a prediction horizon, and controlling operation of the engine system using the filtered heat request to increase a temperature of the SCR catalyst.

  • Publication number: 20180274475
    Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.

  • Publication number: 20180274467
    Abstract: Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.

The method further includes determining an amount of NH3 passing through the SCR catalyst downstream of the urea deposit, comparing the amount of NH3 passing through the SCR catalyst with an NH3 regeneration threshold limit, and terminating the SCR regeneration event when the level of NH3 passing through the SCR catalyst is less than the SCR NH3 regeneration threshold.

  • Publication number: 20170176280
    Abstract: An apparatus includes a sensor module, an offset diagnostic module, and a notification module. The sensor module is in operative communication with a cylinder pressure sensor and structured to acquire cylinder pressure data from the cylinder pressure sensor indicative of an actual in-cylinder pressure of a cylinder of an engine. The offset diagnostic module is structured to interpret the cylinder pressure data to determine an offset of the cylinder pressure sensor based on a reference in-cylinder pressure and the actual in-cylinder pressure. The notification module is structured to provide an offset error notification responsive to the offset being greater than a threshold offset.
