Abstract:
A method and system for identifying cargo-carrying vehicles (CCV) to be included in a vehicle system that are non-propulsion-generating vehicles scheduled to depart from a vehicle yard and travel to one or more destination locations at a predetermined departure time. Further includes, calculating a minimum tractive effort threshold required by one or more propulsion-generating vehicles (PGV) to propel the vehicle system to the one or more destination locations along a route within a predetermined time period. And selecting a set of one or more PGV from a larger group of PGV within the vehicle yard to be included in the vehicle system. The set of one or more PGV produce a tractive effort of at least the minimum tractive effort threshold, and having at least one of a lower fuel consumption or lower emissions than selecting one or more of the remaining PGV from the larger group of PGV, respectively.
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.
