Abstract: An apparatus remotely provides refueling management instructions for a vehicle. One or more initial vehicle parameters are determined, including an initial quantity of fuel, a plurality of route parameters including a starting point, an ending point and an estimated average fuel efficiency of the vehicle, and a plurality of refueling parameters including one or more refueling locations. The sufficiency of an initial quantity of fuel is evaluated in relation to the estimated average fuel efficiency and a distance to be traveled by the vehicle equal to a difference between the ending point and the starting point. One or more current vehicle parameters are interpreted at a first predetermined time, a refueling agenda is created, and an associated predetermined refueling amount at each of the identified one or more refueling locations is determined.

Abstract: A method and related apparatuses and systems for operating an engine that provides a high level of NOX to regenerate particulate matter deposited on a particulate filter. The method includes producing NOX in response to a NOX excess capacity value of a NOX reduction device. The method optionally includes determining that particulate matter exceeds an enhanced passive regeneration threshold amount before providing a high level of NOX. The method optionally includes producing a higher particulate emissions output value to warm the engine exhaust to bring an aftertreatment catalyst to an optimal operating temperature. The method can be implemented with a closed loop feedback controller, which may be configured to reduce particulate matter variation.

Abstract: Methods and systems are disclosed for fuel drift estimation and compensation using exhaust oxygen levels and fresh air flow measurements. An actual fueling to the engine cylinders is determined from the exhaust oxygen level and fresh air flow to the internal combustion engine. The actual fueling is compared to an expected fueling based on the fueling command provided to the internal combustion engine. The difference between the actual fueling and expected fueling is fuel drift error attributed to changes or drift in the fuel injection system and is used to correct or compensate future fueling commands for the fuel drift.

Abstract: Systems and methods for correcting mass airflow sensor drift include an operation conditions module to interpret a base calibration function, a MAF sensor input value, and a current operating condition. A MAF correction module determines an expected MAF value in response to the current operating condition and a predetermined operating condition. The MAF correction module will also determine an adjusted MAF value in response to the expected MAF value, the base calibration function, and the MAF sensor input value. A MAF reporting module is structured to provide the adjusted MAF value.
