Abstract: Methods and apparatus relate to air handling for an internal combustion engine system, particularly utilizing premixed air and fuel. The engine system includes an intake air throttle (IAT) having a position set in response to the engine speed and a variable valve timing module having an intake valve timing set in response to the engine load. The variable valve timing module may be a cam phaser having a position at or between full retard and full advance positions. The engine system may operate in a transient mode or a fuel efficiency mode. The IAT position is adjusted in response to an engine speed error value or set at full throttle. The cam phaser position is adjusted in response to a pressure difference across the IAT, the engine speed, or is set to a limit position.

Abstract: This disclosure provides system and method that can determine hydraulic start of injection (SOI) in engines using an in-cylinder pressure sensor. The system and method iteratively perform a wavelet transform on a signal based on the pressure information provided by the in-cylinder pressure sensors to determine a detail coefficient corresponding to a frequency band containing frequencies of pressure pulsations excited from a fuel jet injected into the cylinder. Hydraulic SOI is determined at the timing when the amplitude of the determined detail coefficient satisfies a predetermined threshold. The system and method provide diagnostic, control, and/or compensation opportunities for fuel injector operation in high pressure fuel rail engine systems without use of expensive or complex fuel injector components.

Abstract: Methods and systems for diagnosing inadequate performance and/or degradation of one or more components of an aftertreatment system are disclosed, the components including at least an oxidation catalyst that is positioned upstream from an SCR catalyst. A performance degradation analysis of the oxidation catalyst is based on a comparison of measurements received from a first nitrous oxide (NOx) sensor located upstream of the oxidation catalyst and a second NOx sensor located downstream from the oxidation catalyst.

Abstract: Systems and methods to control an electric vehicle accessory of an electric vehicle during a charge event are provided. An apparatus includes a controller communicatively coupled to a battery and an electric vehicle accessory. The controller is structured to: receive a battery power limit from the battery management system; receive an indication that the battery is undergoing the charge event; and cause the electric vehicle accessory to recharge by absorbing energy from a charging station during the charge event.

Abstract: A system and method used to predict the state of health of a battery in a powertrain of a vehicle including a vehicle route profile generator arranged to generate a vehicle specific rout profile based on historical vehicle driving information, are disclosed. In one example, the system and method also include a powertrain model to convert the vehicle specific route profile to a predicted battery demand profile, and a state of health profile generator to generate a predicted state of health profile of the battery based on the predicted battery demand. In another example, the system further includes a vehicle performance manager arranged to generate a command to modify operation of the powertrain to extend battery life based on the vehicle specific route profile.

Abstract: A control system for controlling a powertrain of an electric or hybrid electric vehicle is disclosed. The powertrain comprises a battery and a traction motor and is operable in a regenerative braking mode. The control system is configured to generate a deceleration target for the vehicle in the regenerative braking mode, and to generate a torque command for the traction motor based on the deceleration target. By generating a deceleration target for the vehicle during regenerative braking and using the deceleration target to control the torque of the traction motor, more consistent regenerative braking may be provided, particularly when the vehicle is used to carry different loads.

Abstract: A system includes a generator and an engine coupled to the generator. The engine is configured to provide mechanical power to the generator. The system further includes a controller coupled to the engine and the generator. The controller is configured to: receive information regarding an engine operating parameter threshold value at which an engine operating parameter value failed to match a load demand value that is indicative of a load exerted by the generator on the engine, and set the engine operating parameter threshold value as a maximum allowable engine operating parameter value for the engine.
