Abstract: Systems and methods to control operation of a system based on aftertreatment interaction include a controller structured to receive one or more parameters associated with an exhaust aftertreatment system of an electric vehicle, where the one or more parameters are associated with an aftertreatment event associated with the aftertreatment system, determine an operation state of the system based on the one or more parameters, and generate a command structured to adjust operation of the system responsive to the determination of the operation state.

Abstract: The present disclosure provides a method in a vehicle, comprising detecting an engine stop opportunity and recording, in a memory, data corresponding to a first engine stop that occurred in response to detection of the engine stop opportunity. The method further includes detecting an engine stop inhibit, and recording, in a memory, data corresponding to a first missed engine stop wherein the first missed engine stop indicates detection of the engine stop opportunity without an engine stop in response to the detection of the engine stop opportunity.

Abstract: System comprising an internal combustion engine including a crankshaft, a crankshaft sprocket coupled to the crankshaft, an electric motor in mechanical communication with the crankshaft sprocket, a bidirectional engine position sensor coupled to the crankshaft sprocket, a controller in electrical communication with the bidirectional engine position sensor and a non-transitory memory having instructions that, in response to execution by a processor, cause the processor to determine a position of an engine component upon shutdown of the engine, store the position of the engine component at shutdown in the non-transitory memory, and control the electric motor at restart in response to the position of the engine component at shutdown are disclosed. Methods are also disclosed.

Abstract: Systems and methods to control the vehicle speed of a vehicle includes a motor and a controller coupled to the motor. The controller is structured to: determine that a speed of a vehicle is at or above a predetermined speed limit; activate a motor speed governor responsive to an input received by the controller, wherein the motor speed governor is structured to control a vehicle speed; and adjust an output torque based on the vehicle speed being at or above the predetermined speed limit.

Abstract: Systems and methods for implementing a start-stop feature on a vehicle powered at least in party by an internal combustion engine are described. The method includes receiving, at an electronic control unit (“ECU”) of the vehicle, an indication that the vehicle is in line at a drive-thru. The method further includes determining, by the ECU, a number of start-stop events anticipated during the drive-thru. The method includes determining, by the ECU, an approximate stop time for each of the number of start-stop events. The method further includes determining, by the ECU, that a battery of the vehicle has enough remaining charge to power a plurality of vehicle components during implementation of the start-stop feature. The method includes implementing, by the ECU, the start-stop feature in which the internal combustion engine is turned off for at least a portion of the time when the vehicle is stopped.
