Abstract: Systems and apparatuses include a controller including at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, causes the controller to: determine a set of emission regulations based on a location of a vehicle; determine a target temperature of a catalyst of an aftertreatment system of the vehicle in response to the determined set of emission regulations; compare a current temperature of the catalyst to the determined target temperature; and in response to the current temperature of the catalyst being below the determined target temperature, provide a thermal management command to increase the catalyst temperature toward the determined target temperature.

Abstract: Systems, methods and apparatus are disclosed for thermal management of an SCR catalyst in an exhaust aftertreatment system of an internal combustion engine that includes an exhaust throttle but lacks a particulate filter. The thermal management can include interpreting, initiating, and/or completing a thermal management event for the SCR catalyst for removal of contaminants such as hydrocarbons and urea deposits. The thermal management event includes at least one of closing the exhaust throttle and increasing the thermal output of the engine to expose the SCR catalyst to a sufficiently high temperature over a time period that desorbs a sufficient amount of the hydrocarbons and/or removes a sufficient amount of the urea deposits to restore SCR catalyst performance.

Abstract: A system includes a first heater positioned in or proximate to an exhaust aftertreatment system in exhaust gas-receiving communication with an engine, a second heater positioned downstream of the first heater, and a controller coupled to the first and second heaters. The controller is structured to: determine, based on information indicative of a temperature regarding the exhaust aftertreatment system, that the temperature regarding the exhaust aftertreatment system is below a predefined temperature threshold; determine that the second heater is in or likely in an error state; and control a temperature regarding the exhaust aftertreatment system using the first heater in response to determining that the second heater is in or likely in the error state, wherein the first heater controls the temperature regarding the exhaust aftertreatment system after a temperature regarding an engine intake air is at or above a predefined air intake temperature threshold.

Abstract: A system includes an exhaust aftertreatment system coupled to an engine, and a controller including at least one processor coupled to at least one memory device storing instructions that, when executed by the at least one processor, cause the controller to perform certain operations. The operations include estimating an aging of the exhaust aftertreatment system, and adjusting at least one of an entry temperature threshold or an exit temperature threshold for a thermal management mode for the exhaust aftertreatment system based on the aging of the exhaust aftertreatment system.

Abstract: A system includes at least one sensor coupled to an aftertreatment system and a controller having at least one processor coupled to at least one memory device storing instructions that, when executed by the at least one processor, cause the controller to perform operations. The operations include: adjusting an operating point of an engine in response to emissions information from the at least one sensor and based on a fault indicator regarding a component of the system; and, controlling an electric motor in response to the adjustment of the operating point of the engine based on a change in power output from the engine to assist in a desired emissions characteristic.

Abstract: An internal combustion engine system includes an internal combustion engine, a controller, and an increased brake load event communicator. The internal combustion engine includes a first cylinder and a first cylinder deactivation prevention mechanism. The first cylinder is configured to be selectively activated and deactivated. The first cylinder deactivation prevention mechanism is configured to selectively prevent the first cylinder from being deactivated. The controller is communicable with the first cylinder deactivation prevention mechanism. The controller includes an increased brake load event detection module that is configured to selectively control the first cylinder deactivation prevention mechanism to prevent the first cylinder from being deactivated. The increased brake load event communicator is communicable with the controller. The increased brake load event detection module is configured to control the first cylinder deactivation prevention mechanism to prevent the first cylinder from being deactivated based on a communication from the increased brake load event communicator.

Abstract: Controls for improved performance of a vehicle equipped with start-stop control logic are disclosed. Deviation from nominal engine start-stop control logic for the internal combustion engine occurs when a predetermined mission related type of stop event will occur or is occurring that is different from other stop event types that are controlled by the nominal engine start-stop control logic. At least one of a location and a payload associated with the mission related stop event type is provided as an input to the controller before the vehicle arrives at the stop event so that operating parameters of the vehicle are controlled accordingly.
