    摘要： A vehicle control system and a method of operating thereof may include determining a first ratio at which to operate a vehicle system at a first location along a route along which the vehicle system moves. The first ratio may be based on an amount of a first fuel of a first fuel source relative to an amount of a second fuel of a second fuel source. The vehicle system may be powered by one or more of the first or the second fuel sources. First operational settings at which to control the vehicle system may be determined based on the first ratio between the first and second fuel sources at the first location along the route. Operation of the vehicle system may be controlled according to the first operational settings to move the vehicle system according to the first ratio at the first location along the route.

    摘要： A work vehicle may include an internal combustion engine, aftertreatment system, and at least one controller. The controller is configured to use a temperature of the aftertreatment system to determine a hydrocarbon level of the aftertreatment system, and set an idle speed of the engine to high idle if the hydrocarbon level is above a hydrocarbon ceiling, to ultra-low idle if the hydrocarbon level is below a hydrocarbon floor, and to low idle if the hydrocarbon level is between the hydrocarbon floor and the hydrocarbon ceiling.
