Abstract: The enclosed disclosure relates to vehicle systems in which an engine, a particulate filter fluidly coupled with the engine, a selective catalytic reduction (SCR) system fluidly coupled with the engine downstream of the particulate filter, an electrical heating device implemented with the particulate filter, and a controller operatively coupled with the engine and the electrical heating device, are implemented. The controller can detect, when the engine is turned off, a condition for turning on the engine, detect a temperature of the particulate filter of the SCR system, activate the electrical heating device in response to the detected temperature being below a lower temperature threshold, and turn on the engine in response to the detected temperature being at or above the lower temperature 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 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 an aftertreatment system heater of an exhaust aftertreatment system coupled to an engine A controller coupled to the aftertreatment system heater is configured to determine a condition of an exhaust gas from an engine and compare the condition to a predefined threshold. If the condition of the exhaust gas does not meet the predefined threshold, the controller is configured to determine whether an engine operating condition is met for activating a cylinder deactivation operating mode for the engine. If the engine operating condition is met, the controller is configured to operate the engine in the cylinder deactivation operating mode by deactivating a cylinder of a plurality of cylinders. If the engine operating condition is not met, the controller is configured to activate the aftertreatment system heater to heat the exhaust gas.
