Abstract: A control system, apparatus, and method integrates vehicle speed management and predicted gear shifting of a vehicle by determining current and future engine power requirements from the current and forward-looking route conditions to improve performance, drivability, and/or fuel economy of the vehicle over what is achievable through conventional gear state selection via static calibration tables and conventional shifting strategies. The selection of the vehicle reference speed is responsive to a gear selection to provide increased fuel economy, decreased trip time or combinations thereof.

Abstract: An apparatus includes an initial planning module, a tandem implementation module, and a scheduler module. The initial planning module is structured to interpret one or more fleet delivery requirements, assets, drivers, and vehicle descriptions. The tandem implementation module is structured to determine a travel schedule with respect to a first vehicle and a second vehicle that enables the first vehicle and the second vehicle to travel in tandem for a least a portion of a route in response to input from the initial planning module. The scheduler module is structured to provide a fleet delivery schedule to the first vehicle and the second vehicle in response to the determination of the tandem implementation module.

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.
