Abstract: A method is provided for reducing emissions from a hybrid vehicle having an exhaust aftertreatment system. The method includes: receiving, by a controller, emissions data regarding an emissions level of a hybrid vehicle having an exhaust aftertreatment system from a sensor; determining, by the controller, that the emissions level is at or above a predefined threshold; adjusting, by the controller, an operating point of an engine of the hybrid vehicle based on the emissions level being at or above the predefined threshold; and controlling, by the controller, an elector motor in response to the adjustment of the operating point of the engine to compensate for a change in power output from the engine and to reduce the emissions level to below the predefined threshold.

Abstract: A method includes receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and an exhaust gas characteristic. The method includes comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold, and comparing, by the controller, the exhaust gas characteristic to a characteristic threshold. The method includes, responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage or disengage to warm the aftertreatment system of the vehicle.

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 a passive NOx adsorber (PNA) for receiving and treating exhaust gas generated by an engine and a controller. The controller is configured to: while exhaust gas is received by the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; and in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.

Abstract: A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to: while controlling the bypass valve to direct exhaust gas to the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.

Abstract: A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to, determine that the catalyst is operating under cold start conditions, control the bypass valve to direct exhaust gas to the PNA, determine that the catalyst is no longer operating under cold start conditions and continue to control the bypass valve to direct exhaust gas to the PNA for a predetermined duration, and after the elapse of the predetermined duration, control the bypass valve to direct exhaust gas to the catalyst bypassing the PNA. The controller is also configured to detect a high transient torque demand while the exhaust gas is provided to the PNA, and split the torque demand between the engine and an electric motor.
