Abstract
A control system includes a transmission with a directional clutch and control assembly clutches coupled together and configured for selective engagement to transfer power. A controller is configured to selectively actuate the directional clutch and the control assembly clutches with clutch commands to implement a first split mode in which combined power is transferred to drive the output shaft, a first direct drive mode in which power from only the engine to drive the output shaft, and a first series mode in which power is transferred from primarily the at least one motor to drive the output shaft. The controller is further configured to implement a transient boost function within at least a portion of the first series mode in which the at least one directional clutch is partially engaged to supplement power from the at least one motor with power from the engine to drive the output shaft.
