Abstract: 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.

Abstract: A method includes obtaining creep measurements and tractive/braking measurements from at least one vehicle system at different locations along a route segment while the at least one vehicle system moves through the route segment. The method also includes calculating tribology characteristics of the route segment at the different locations. The tribology characteristics are based on the creep measurements and the tractive/braking measurements from the at least one vehicle system. The tribology characteristics are indicative of a friction coefficient of the route segment at the different locations. The method also includes determining an effectiveness of a friction modifier applied to the route segment based on the tribology characteristics.

Abstract: A power converter control system includes a first power converter, at least one additional power converter, a first control module, and an additional control module. The first power converter receives direct current and outputs alternating current as a first power output. The additional power converter receives direct current and outputs alternating current as an additional power output. The first control module controls timing of events of the first power converter. The additional control module is associated with the additional power converter and controls timing of events of the additional power converter. The first control module communicates first information regarding the timing of the first power converter to the additional control module. The additional control module is configured to adjust the timing of the additional power converter to correspond with the timing of the first power converter.

Abstract: 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.

Abstract: A method for vehicle control comprises determining a braking capability of a braking system of a vehicle, and modifying application of at least one control parameter by a control system of the vehicle based on the determined braking capability. Braking capability may be determined by activating the braking system of the vehicle to apply a braking force on the vehicle, and concurrently, applying a level of tractive effort of the vehicle that is sufficient to overcome the braking force. The braking capability is determined based on the level of tractive effort.
