Abstract: Systems and methods for conditioning an aftertreatment system. For example, a computer-implemented method for conditioning an aftertreatment system of a hybrid system including an electric motor and a combustion engine includes: determining whether the aftertreatment system is in a first temperature zone below a first temperature threshold; determining whether a power demand corresponding to the operation of the hybrid system is in a first power demand zone below a power threshold; and if the aftertreatment system is determined to be in the first temperature zone and the power demand of the hybrid system is determined to be in the first power demand zone, setting the hybrid system to compressor mode to heat the aftertreatment system.

Abstract: In some implementations, a method may include obtaining target fault data indicating a preselected fault for a vehicle having a hydrogen source. In addition, the method may include obtaining vehicle fault data indicating a fault of the vehicle. The method may include identifying a match between the fault and the preselected fault. Moreover, the method may include purging, in response to the identifying the match, hydrogen from the hydrogen source so as to reduce consequences of a battery thermal event by reducing the likelihood of a hydrogen-fueled fire.

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: A method for optimizing operation of a fleet of vehicles includes providing an optimization network including a plurality of nodes and a plurality of connections therebetween. The nodes define all potential destinations in the network for freight delivery or pickup. The connections define all potential sequences of nodes traversable over the network. The method determines a pre-optimization simulation matrix including a plurality of sets of energy expenditures for traversing respective ones of each of the connections. Each of the plurality of sets of energy expenditures accounts for permutations of a plurality of different vehicle powertrains present in a fleet of vehicles. The method performs an optimization using the pre-optimization simulation matrix, fleet information indicating locations and energy states of a plurality of vehicles in the vehicle fleet, mission information indicating a pickup or delivery destination for a plurality of items of freight, and a fleet optimization objective.

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: 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.
