  • Patent number: 10077727
    Abstract: A fuel control module controls fuel injection of an engine based on a predetermined lean air/fuel ratio. The predetermined lean air/fuel ratio is fuel lean relative to a stoichiometric air/fuel ratio for the fuel. A cylinder control module selectively deactivates opening of intake and exhaust valves of M cylinders of the engine to increase removal of nitrogen oxide (NOx) from exhaust. M is an integer greater than 0 and less than a total number of cylinders of the engine. The fuel control module further: disables fueling of the M cylinders while opening of the intake and exhaust valves of the M cylinders is deactivated; and, while fueling of the M cylinders is disabled and opening of the intake and exhaust valves of the M cylinders is deactivated, controls fuel injection of other cylinders based on a predetermined rich air/fuel ratio that is fuel rich relative to the stoichiometric air/fuel ratio.

  • Patent number: 10077050
    Abstract: The methods and system described herein may be used to assist an automated driving system of a host vehicle. The methods and system may, in an exemplary embodiment, be used to determine whether a host vehicle or a target vehicle is cutting out and, accordingly, control the acceleration and/or other driving features of the host vehicle. Generally, the methods described herein contain the steps of determining that a vehicle is cutting out, determining which vehicle is cutting out, and then controlling the acceleration of the host vehicle based on the previous determinations. The determination of which vehicle is cutting out is made based on readings gathered by the host vehicle from one or more automated driving sensors. By using target vehicle sensor data in conjunction with lane marking sensor data, the host vehicle can determine, not only that a vehicle is cutting out, but which vehicle(s) are cutting out.

  • Publication number: 20180258813
    Abstract: Disclosed are SCR predictive control systems, methods for using such control systems, and motor vehicles with SCR employing predictive control. A method for regulating operation of an SCR system includes receiving sensor signals indicative of NOx output downstream from an SCR catalyst, and sensor signals indicative of exhaust gas temperature upstream from the SCR catalyst. The method determines if a model error condition has occurred for the NOx output signal and, responsive to such an occurrence, modulating dosing injector output for at least a calibrated designated time period. Upon expiration of the designated time period, the dosing injector is activated and commanded to inject reductant in accordance with a modulated dosing value. After the dosing injector injects the modulated dosing value of reductant, the method determines if the SCR system is underdosing or overdosing based on a response shape of signals received from the outlet NOx content sensor.
