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: The enclosed disclosure relates to vehicle systems in which an engine, a particulate filter fluidly coupled with the engine, a selective catalytic reduction (SCR) system fluidly coupled with the engine downstream of the particulate filter, an electrical heating device implemented with the particulate filter, and a controller operatively coupled with the engine and the electrical heating device, are implemented. The controller can detect, when the engine is turned off, a condition for turning on the engine, detect a temperature of the particulate filter of the SCR system, activate the electrical heating device in response to the detected temperature being below a lower temperature threshold, and turn on the engine in response to the detected temperature being at or above the lower temperature threshold.

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.

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: A system includes at least one sensor coupled to an aftertreatment system and a controller having at least one processor coupled to at least one memory device storing instructions that, when executed by the at least one processor, cause the controller to perform operations. The operations include: adjusting an operating point of an engine in response to emissions information from the at least one sensor and based on a fault indicator regarding a component of the system; and, controlling an electric motor in response to the adjustment of the operating point of the engine based on a change in power output from the engine to assist in a desired emissions characteristic.

Abstract: A powertrain system includes an engine coupled to a turbocharger and a timer, a motor generator coupled to the engine and a battery, and a controller. The controller is structured to receive data indicative of a state of charge from the battery, determine whether the state of charge is at or below a high predefined threshold, modulate control on the engine and the timer in response to determining the state of charge is above the high predefined threshold, determine whether the state of charge is above a low predefined threshold in response to the state of charge being at or below the high predefined threshold, and modulate control of the engine and the timer in response to determining the state of charge is at or below the low predefined threshold.
