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.

Control system and method for controlling an operational mode of a vehicle via multiple clutch assemblies

A capacity estimator determines a total maximum allowable power storage capacity for a work vehicle. A timer times the operating time of the work vehicle in an electrically propelled mode. A load manager, a driver or both decrease the available power to at least one of a drive motor of the work vehicle and an ancillary load over the operating time to conserve the available power stored for operating at least one critical work vehicle.
