摘要： A system includes a controller having at least one processing circuit including at least one memory coupled to at least one processor. The controller is configured to: receive data regarding operation of an engine indicating that one or more cylinders of a plurality of cylinders of the engine is compromised; cause the engine to operate in a modified engine operating mode whereby operation of the one or more cylinders that is compromised is modified; cause the engine to operate in a non-modified engine operating mode whereby operation of the one or more cylinders that is compromised is not modified responsive to receiving information regarding a predetermined condition despite the data regarding operation of the engine indicating that the one or more cylinders of the plurality of cylinders of the engine is compromised.

摘要： 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.

摘要： A method includes determining, by a controller, that a transient event for a hybrid vehicle is occurring; determining, by the controller, an increase of power demand for the hybrid vehicle based on the determined transient event; directing, by the controller, an amount of power from an electric motor of the hybrid vehicle to a powertrain of the hybrid vehicle based on the increase in power demand, the amount of power from the electric motor determined based on at least one of a state of charge of a battery of the hybrid vehicle; and increasing, by the controller, an amount of power from an engine of the hybrid vehicle as a power output from the electric motor decays to avoid an engine power output spike from the engine based on the determined increase in power demand.

摘要： 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.

摘要： A system includes an exhaust aftertreatment system including a particulate filter and a controller. The controller is configured to: receive information comprising a temperature regarding a filter of the aftertreatment system; and responsive to determining that the temperature regarding the filter is below a temperature threshold, command the engine to operate according to a first firing fraction. The first firing fraction may define a number of active cylinders of the engine relative to a total number of cylinders of the engine, and correspond to a predetermined temperature value of the filter.

摘要： Systems and methods for controlling a hybrid system. For example, a computer-implemented method includes determining a system temperature zone of the aftertreatment system as being in: a first temperature zone below a first temperature threshold, a second temperature zone from the first temperature threshold to a second temperature threshold, or a third temperature zone above the second temperature threshold; determining a power demand corresponding to the operation of the hybrid system as being in: a first power demand zone if the power demand is below a power threshold, or a second power demand zone if the power demand is equal to or greater than the power threshold; and determining a control strategy based at least in part on the determined system temperature zone and the determined power demand.
