  • Control system and method for controlling an operational mode of a vehicle via multiple clutch assemblies
    Patent number: 8100240
    Abstract: A first clutch assembly has an active state for transmitting rotational energy and an inactive state for not transmitting rotational energy. A generator has a generator shaft associated with the first clutch assembly. A second clutch assembly has an active state for transmitting rotational energy and an inactive state for not transmitting rotational energy. A transmission has a transmission shaft directly or indirectly associated with the second clutch assembly. A third clutch assembly has an active state for transmitting rotational energy and an inactive state for not transmitting rotational energy. An engine has an engine shaft associated with the third clutch assembly. A controller establishes an operational mode of the vehicle by controlling the states of the first clutch assembly, the second clutch assembly, and the third clutch assembly.
    Type: Grant
