System, method, and apparatus for controlling power output distribution in a hybrid power train

摘要

A system includes a hybrid power train including an engine, a first electrical torque provider, and a second electrical torque provider. The system further includes a load mechanically coupled to the hybrid power train. The hybrid power train further includes a clutch coupled to the engine and the second electrical torque provider on a first side, and coupled to the first electrical torque provider and the load on a second side. The system further includes an electrical energy storage device electrically coupled to the electrical torque providers. The system further includes a controller that performs operations to smooth torque commands for the engine and the second electrical torque provider in response to determining that a clutch engage-disengage event occurring or imminent.

1. A system comprising:
a hybrid power train including an engine, a first electrical torque provider, a second electrical torque provider mechanically coupled to the engine by a first shaft, a load mechanically coupled to the first electrical torque provider by a second shaft, and a clutch mechanically coupling the first and second shafts between the first and second electrical torque providers; an electrical energy storage device electrically coupled to the first electrical torque provider and the second electrical torque provider; and a controller structured to smooth torque commands for the engine and the second electrical torque provider in response to determining that one of a clutch engaging event or a clutch disengaging event is one of occurring or imminent, wherein the controller is further structured to close the clutch in response to determining a speed of the first shaft is within a predetermined speed threshold value of a speed of the second shaft.
