Abstract
A control system for operating a work vehicle powertrain includes an engine configured to generate power for an output shaft. The control system includes a transmission positioned operatively between the engine and the output shaft and configured to selectively transfer the power along a power flow path between the engine and the output shaft. The transmission includes an input shaft; at least one intermediate shaft; at least one directional clutch; and intermediate clutches configured for selective engagement to transfer power between the at least one intermediate shaft and the output shaft. A controller is configured to receive a vehicle stop request to stop the work vehicle; implement, upon receiving the vehicle stop request, a clutch braking function; and generate, upon the implementation of the clutch braking function, clutch commands to engage at least two of the intermediate clutches selected such that the output shaft is slowed and stopped.
