CONTROL OF A HYBRID POWERTRAIN SYSTEM

In some implementations, a controller for a hybrid powertrain system may cause disengagement of an engine from an electric machine via a clutch based on a state of charge (SOC) of one or more batteries connected to the electric machine at least meeting an SOC threshold. Disengagement of the engine m...

Beschreibung
Zusammenfassung:	In some implementations, a controller for a hybrid powertrain system may cause disengagement of an engine from an electric machine via a clutch based on a state of charge (SOC) of one or more batteries connected to the electric machine at least meeting an SOC threshold. Disengagement of the engine may cause the hybrid powertrain system to operate in an electric-only mode for powering a load. The controller may detect a power event that includes at least one of a level of demand of the load exceeding a demand threshold, or the SOC of the one or more batteries being below the SOC threshold. The controller may cause, based on detection of the power event, engagement of the engine with the electric machine via the clutch. Engagement of the engine may enable the hybrid powertrain system to operate in a hybrid mode for powering the load.
