Abstract: This disclosure provides a system and method for controlling internal combustion engine system to reduce operation variations among plural engines. The system and method utilizes single-input-single-output (SISO) control in which a single operating parameter lever is selected from among exhaust gas recirculation (EGR) fraction and charge air mass flow (MCF), and a stored reference value associated with the selected lever is adjusted for an operating point in accordance with a difference between a measured emissions characteristic and a pre-calibrated reference value of the emissions characteristic for that operating point. Adjusting the selected operating parameter lever towards the theoretical pre-calibrated reference value of the operating parameter lever for each of plural operating points can reduce engine-to-engine variations in engine out emissions.

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.
