Abstract: Apparatuses, methods, and systems comprising vehicle fleet management systems are disclosed. One embodiment is a method that provides a plurality of predetermined powertrain trim templates, where each of the plurality of predetermined powertrain trim templates specifies a plurality of powertrain trim parameters implementable by an electronic powertrain control system to control one or more operational response characteristics of the powertrain. The method includes selecting one of the plurality of predetermined powertrain trim templates and one of a plurality of vehicles of a vehicle fleet to receive the selected one of the plurality of predetermined powertrain trim templates. In response to the act of selecting one of the plurality of predetermined powertrain trim templates, the method transmits via a telematics network one or more modified powertrain trim parameters. Further, the method receives the modified powertrain trim parameters with a telematics system of the selected one of the plurality of vehicles of the vehicle fleet. Also, the method applies the modified trim parameters with the electronic powertrain control system to control the one or more operational response characteristics of the powertrain.

Abstract: One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.
