METHOD OF MANAGING AVAILABLE OPERATING REGIONS WITHIN OPERATING STATES IN AN ELECTRIC POWERTRAIN

摘要

A method of managing an operating state of an electrified powertrain includes a controller identifying a plurality of available operating regions defined by at least one available operating state of the powertrain, each operating region representing a distinct range of operating conditions. The available operating regions include an avoidance region defining a plurality of unwanted operating conditions and separating a first allowable operating region from a second allowable operating region such that the first and second allowable operating regions are noncontiguous. The method identifies at least one ideal operating condition in each of the available operating regions, determines a preferability factor and stabilization factor for each of a current and each of the ideal operating conditions, and arbitrates the factors to identify one of the current and ideal operating conditions as an optimized operating condition to produce a required parameter value.

1. A method of managing an operating state of an electrified powertrain, the method comprising:
determining, via a controller, at least one available operating state of the electrified powertrain; determining, via the controller, a plurality of operating regions defined by the at least one available operating state; wherein the at least one available operating state is operable in a plurality of operating conditions; wherein each respective one of the plurality of operating regions represents a distinct range of the plurality of operating conditions within a respective one of the at least one available operating state; wherein the at least one available operating state includes a current operating state; wherein the plurality of operating regions includes a current operating region defined by the current operating state; wherein the plurality of operating conditions includes a current operating condition within the current operating region; determining, via the controller, the current operating condition; identifying, via the controller, a respective ideal condition in each respective one of the available operating regions;
determining, via the controller, a preferability factor for the current operating condition and each respective ideal operating condition;determining, via the controller, a stabilization factor for the current operating condition and each respective ideal operating condition; andarbitrating, via the controller, the preferability factor and the stabilization factor of the current operating condition and each respective ideal operating condition to identify an optimized operating condition.
