Methods, systems, and apparatuses for driveline load management

摘要

A method includes interpreting a powertrain load variation amplitude and an internal combustion engine output profile. The method further includes determining an engine output differential in response to the powertrain load variation amplitude and the internal combustion engine output profile. The method further includes providing an energy accumulator sizing parameter and/or an alternate motive power provider sizing parameter in response to the engine output differential.

1. A method, comprising:
interpreting a powertrain load variation amplitude of a powertrain of a first vehicle from duty cycle data of motive power of the powertrain and an internal combustion engine output profile of an internal combustion engine of the powertrain with a controller, wherein interpreting the powertrain load variation amplitude comprises performing a frequency component analysis of a load description of the powertrain to determine a largest load amplitude of the load description; determining an engine output differential in response to the largest load amplitude from the powertrain load variation amplitude and the internal combustion engine output profile with the controller; and determining, with the controller, one of an energy accumulator stored energy rating sizing parameter from the engine output differential integrated over a period of time referenced to the powertrain load variation amplitude and an alternate motive power provider power rating sizing parameter from a size of the engine output differential, wherein the one of the energy accumulator stored energy rating sizing parameter and the alternate motive power provider power rating sizing parameter determines a size of a non-combustion motive power source to be installed in a second vehicle to meet motive power demands of the second vehicle that deviate from the internal combustion engine output profile, wherein the second vehicle includes an internal combustion engine having the internal combustion engine output profile.
