Method for managing available operating regions within operating states in an electric powertrain

Abstract

Method (100) for managing an operating state (80) of an electrified powertrain (10), wherein the method (100) comprises that: via a controller (50) at least one available operating state (80) of the electrified powertrain (10) is determined (105); via the controller (50) a plurality of operating regions (82, 84, 86) are determined (110) which are defined by the at least one available operating state (80); wherein the at least one available operating state (80) can be operated in a variety of operating conditions; wherein each of the multiple operating regions (82, 84, 86) represents a unique range of the multiple operating conditions in a respective one of the at least one available operating state (80); wherein the at least one available operating state (80) includes a current operating state; wherein the multitude of operating regions (82, 84, 86) includes a current operating region which is defined by the current operating state; where the multitude of operating conditions includes a current operating condition within the current operating region; The current operating condition is determined via the controller (50) (125); via the controller (50) an ideal condition is identified in each of the available operating regions (82, 84, 86) (130); via the controller (50) a preference factor is determined for the current operating condition and for each respective ideal operating condition (140); A stabilization factor for the current operating condition and for each respective ideal operating condition is determined via the controller (50) (145); and The preference factor and the stabilization factor of the current operating condition and of each respective ideal operating condition can be assessed via the controller (50) (150) in order to identify an optimized operating condition; where the preference factor is defined by a performance-based factor and / or an efficiency-based factor and / or an avoidance-based factor; where the stabilization factor is defined at least partially by a response time for a transition from the current operating condition to a respective requested operating condition; wherein the performance-based factor is defined at least partially by a performance characteristic of the powertrain (10), the efficiency-based factor is defined at least partially by the power utilization of the powertrain (10), and the avoidance-based factor is defined at least partially by the detectability of an unwanted condition.
