Patent ID: 6880687

Claim:
A vehicular transmission system comprising an engine, a transmission having an input shaft, a master friction clutch for drivingly connecting the engine to the transmission, an inertia brake for selectively controlling rotation of the input shaft, and at least one control unit for receiving an input and processing the input according to logic rules to issue an output to system components including at least the inertia brake, the system further characterized by: the master friction clutch being a centrifugally operated clutch; the control unit, in at least one mode of operation, selectively prohibits operation of the inertia brake; at least one input corresponding to an engagement status of the master friction clutch; the control unit including logic rules that control operation of the system in response to the engagement status of the master friction clutch; and at least one output corresponding to a command to log a fault or prohibit operation of the inertia brake in response to an engagement of the master friction clutch during the at least one mode of operation.
