摘要： A locomotive propulsion system includes an engine assisting apparatus and an engine control unit that monitors an output parameter of a locomotive engine. The control unit determines whether the engine output decreases sufficiently low to at least partially de-fuel the engine and to activate an assisting apparatus. This assisting apparatus rotates a shaft of the engine with or without the engine also rotating the shaft. Rotation of the shaft by the assisting apparatus can be used to power traction motors or other loads of the locomotive while reducing fuel consumption and/or emission generation by the engine.

摘要： A method and system determine, during movement of a vehicle system along a route, a tractive load demanded by the vehicle system to propel the vehicle system along the route. The vehicle system includes a propulsion-generating vehicle having plural individually controllable traction motors. A first selected set of the traction motors for deactivation is identified during the movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system. The traction motors in the first selected set are deactivated while at least one of the traction motors in a first remaining set of the traction motors continues to generate tractive effort to propel the vehicle system. The traction motors that are selected for deactivation may all be on the same vehicle in the vehicle system, or may be on different vehicles of the same vehicle system.

摘要： A vehicle control system controls operation of motors of a vehicle and determines whether there is sufficient stored electric energy to power the vehicle through an unpowered segment of a route. The controller changes operation of the vehicle to ensure that the vehicle can travel completely through the unpowered segment by switching which energy storage device provides energy, changing vehicle speed, changing motor torque, changing which route is traveled on, selecting fewer motors to power the vehicle, requesting rendezvous with a recharging vehicle, running the energy storage devices in a degraded mode, initiating a motor to generate power to aid in propulsion and/or recharge the energy storage devices, selecting a different route, controlling the vehicle to draft or mechanically couple to another vehicle, and/or controlling the vehicle to gain momentum or to generate an overcharge.
