Abstract: Methods and systems for operating a vehicle on a reduced traction surface are disclosed. A controller of the vehicle obtains at least one of: ambient information or GPS information, determines a derate increment size based on the ambient or GPS information, imposes a sustained derate by applying a torque limit on a braking torque of the vehicle based on the derate increment size in response to detecting a traction control event. The controller also determines a verification period and a derate reduction period based on the ambient or GPS information to reduce the sustained derate in response to detecting a lack of traction control event during the verification period at a rate determined by the derate reduction period.

Abstract: Control of a spark ignited internal combustion in response to an exhaust manifold pressure measurement of an engine is disclosed. An engine out NOx amount for at least one cylinder is determined at least in part in response to the exhaust manifold pressure measurement and a brake mean effective pressure of the at least one cylinder. An operating condition of the engine is adjusted in response to the engine out NOx amount.

Abstract: Systems and methods to control the vehicle speed of a vehicle includes a controller communicatively coupled to a motor and a brake mechanism. The controller is structured to receive an indication of a desired change in the vehicle speed, activate a motor speed governor responsive to the brake mechanism being in a released state, adjust an output torque responsive to the vehicle speed, wherein as a load corresponding to the motor increases the vehicle speed decreases.

Abstract: Methods and systems for diagnosis and control of an internal combustion engine using vibration data obtained from a vibration sensor mounted on the engine includes filtering vibration data within a predetermined engine combustion time period, where the vibration data is indicative of a vibration of an internal combustion engine, determining a peak cylinder pressure (PCP) of a combustion cycle of the internal combustion engine based on the filtered vibration data, determining a location of peak cylinder pressure (LPP) of the combustion cycle of the internal combustion engine based on the filtered vibration data, where the PCP and the LPP are indicative of a performance characteristic of the combustion cycle, and modifying an ignition timing of the internal combustion engine based on the determined PCP and LPP.

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: 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: An apparatus includes an energy storage circuit, an input circuit, and a hybrid management circuit. The energy storage circuit is structured to receive information regarding a state of charge (SOC) and a state of health (SOH) of an energy storage device structured to store energy. The input circuit is structured to receive an indication of a torque demand. The hybrid management circuit is structured to: determine a SOH adjustment factor based on the SOH of the energy storage device; determine a first torque output for a genset based on the SOH adjustment factor and the SOC of the energy storage device, the genset including an engine and a first motor-generator; and operate the genset to provide the first torque output and to generate an amount of energy for a second motor-generator to meet the torque demand according to the SOH adjustment factor.
