Abstract
A control system for a work machine includes an engine, a torque converter, and a lock-up clutch assembly. The lock-up clutch assembly includes a lock-up clutch that can be positioned in an engaged state, for bypassing the torque converter, or a disengaged state. The control system includes a controller configured to determine that the engine is in a cranking state, and cause, based on determining that the engine is in the cranking state, the lock-up clutch to be positioned in the engaged state. The controller is also configured to determine that the lock-up clutch is in the engaged state. The controller is further configured to determine, based on an engine speed, that the engine has started, and cause, based on determining that the engine has started, the lock-up clutch to be positioned in the disengaged state.
