摘要:
A machine is described that includes an engine, a multi-clutch transmission and a controller. The controller is configured with computer-executable instructions for managing operation of the multi-clutch transmission to avoid autoengagement of a disengaged clutch. The computer-executable instructions configure the controller to receive sensor signals indicative of current operating status of the machine; determine, based upon the sensor signals, a configured minimum engine speed needed to avoid autoengagement of the disengaged clutch; and conditionally increase an engine speed based upon a comparison of the configured minimum engine speed and a sensed current engine speed. The machine includes a continuously variable transmission coupled to the multi-clutch transmission, and the controller is configured to adjust the continuously variable transmission ratio to counter the engine speed increase and thus maintain a current clutch output speed when increasing the engine speed to avoid autoengagement of a disengaged clutch.
