Fuel control system

A system comprising:

• a plurality of propulsion-generating vehicles in a vehicle system, wherein the plurality of propulsion-generating vehicles comprise engines or fuel cells;
• a control device communicably coupled with the plurality of propulsion-generating vehicles in a vehicle system;
• the control device configured to:
• calculate modeled amounts of fuel predicted to be consumed by engines or fuel cells of the plurality of propulsion-generating vehicles in the multi-vehicle system, the modeled amounts of fuel calculated using a fuel consumption model that associates different values of the modeled amounts of fuel with operating parameters of the engines or fuel cells;
• determine consumed amounts of fuel that are consumed by the engines or fuel cells of the plurality of propulsion-generating vehicles;
• calculate difference values between the modeled amounts of fuel and the consumed amounts of fuel for each of the plurality of propulsion-generating vehicles;
• re-allocate loads placed on the plurality of propulsion-generating vehicles based on the difference values of each of the plurality of propulsion-generating vehicles in the multi-vehicle system;
• determine the consumed amounts of fuel after re-allocating the loads among the plurality of propulsion-generating vehicles;
• and
• re-calculate the difference values between the modeled amounts of fuel and the consumed amounts of fuel after re-allocating the loads among the plurality of propulsion-generating vehicles, wherein the difference values are smaller after re-allocating the loads among the plurality of propulsion-generating vehicles compared to prior to re-allocating the loads among the plurality of propulsion-generating vehicles, wherein at least a portion of the load is re-allocated from a first propulsion-generating vehicle with larger difference values to at least a second propulsion-generating vehicle with smaller difference values.
