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: Platooning vehicles can result in operational cost savings. Disclosed is a method of apportioning costs that are incurred/saved as a result of platooning vehicles, as well as assigning penalties for unfair platoon participation. For example, platooning history of a vehicle can be tracked, and if that vehicle acts too often as a trailing vehicle in a series of platoons then a penalty might be assigned to that vehicle. Also disclosed is a technique for operating a platoon in the presence of external factors such as municipal regulations, merging traffic, emergency vehicles, etc.

Abstract: Presented herein are systems and methods of selectively activating legs of converters. The system can include a power converter comprising a plurality of legs to convert electrical power conveyed between a source and a load. The system can include a controller structured to be coupled with the power converter. The controller can identify a parameter defining an operating condition of the power converter. The controller can determine a number of legs of the power converter to use based on the parameter. The controller can identify a metric indicating a utilization of each leg of the plurality of legs. The controller can cause activation of at least a subset of legs of the plurality of legs in accordance with the number of legs and the metric, to convey the electrical power between the source and the load.

Abstract: The system disclosed herein is for communication between a first electric vehicle and a second electric vehicle following the first electric vehicle on a route. The system includes a controller communicatively coupled to a battery associated with the second electric vehicle. The controller is configured to acquire a set of operating parameters associated with the first electric vehicle from the first electric vehicle and generate an adjustment command configured to adjust a component operating parameter of at least one component of the second electric vehicle based on the set of operating parameters. The set of operating parameters includes charge station data indicating whether a charge station along the route is unavailable for use.

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.
