Abstract: A method for managing emissions from a vehicle having an aftertreatment system is provided. The method includes: receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and a power output of an engine of the vehicle; comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold; comparing, by the controller, the power output to a power output threshold; and responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage and disengage to warm the aftertreatment system of the vehicle.

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.

Abstract: The enclosed disclosure relates to hybrid vehicles and systems with an engine, a drivetrain with a clutch and a transmission, an electric machine, and a controller. The controller receives lookahead information within a lookahead window and present state information of the hybrid vehicle. The controller determines a predicted coasting opportunity exceeding a predetermined threshold within the lookahead window and determines a cruise control reference speed, a power split between the engine and the electric machine, and a timing of enabling engine-off coasting during the coasting opportunity. The controller deactivates the engine and disengages the clutch at a start of the coasting opportunity when the engine-off coasting is enabled.

Abstract: 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.

Abstract: The present disclosures relate to methods and systems for a hybrid powertrain. The hybrid powertrain system includes an integrated axle configured to provide mechanical power to a first pair of wheels, the integrated axle comprising a first motor-generator and a first drive axle such that the first motor-generator and at least a portion of the first drive axle are mechanically coupled to a common housing. The system also includes a second motor-generator configured to be mechanically coupled with an engine via a first clutch and mechanically coupled with a second drive axle via a second clutch, the second drive axle mechanically coupled with a second pair of wheels. A controller is electrically coupled with the first and second motor-generators, the engine, and the first and second clutches, the controller configured to enable a fully electric mode, a series hybrid mode, a parallel hybrid mode, and a regenerative mode of operation.

Abstract: Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine and an energy storage device are disclosed. The methods and systems involve obtaining lookahead information and current state information, wherein the lookahead information includes a predicted vehicle speed, and the current state information includes a current state of charge (SOC) for the energy storage device coupled to the electric motor; and determining, based on the lookahead information and the current state information, a target power split between the energy storage device and the engine.

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.
