摘要： This disclosure provides a system and method for determining cylinder deactivation in a vehicle engine to optimize fuel consumption while providing the desired or demanded power. In one aspect, data indicative of terrain variation is utilized in determining a vehicle target operating state. An optimal active cylinder distribution and corresponding fueling is determined from a recommendation from a supervisory agent monitoring the operating state of the vehicle of a subset of the total number of cylinders, and a determination as to which number of cylinders provides the optimal fuel consumption. Once the optimal cylinder number is determined, a transmission gear shift recommendation is provided in view of the determined active cylinder distribution and target operating state.

摘要： A system and method for identifying and analyzing a route using an inexpensive GPS system is provided. The system and method provides a location for storing GPS and vehicle operating data for at least one route, requiring a plurality of runs over the at least one route. Once a predetermined minimum number of runs have been reached, the system and method define a route segment, interpolate additional data points using the GPS and vehicle operating data, synchronize the data over the plurality of runs, and analyze the data. The analyzed data is then provided to a module capable of controlling the operation of an internal combustion engine. The analyzed data is forward-looking in that it permits anticipation of vehicle operation, and more particularly, engine and transmission operation.

摘要： A vehicle operating condition profile can be determined over a given route while also considering imposed constraints such as deviation from time targets, deviation from maximum governed speed limits, etc. Given current vehicle speed, engine state and transmission state, the present disclosure optimally manages the engine map and transmission to provide a recommended vehicle operating condition that optimizes fuel consumption in transitioning from one vehicle state to a target state. Exemplary embodiments provide for offline and online optimizations relative to fuel consumption. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.

摘要： Systems and methods of vehicle fuel quantity management are provided to assist in determining an optimal quantity of fuel to carry on-board a vehicle. Certain routes are sufficiently short so to not require a completely filled fuel tank to traverse. Additionally, most routes have an abundance of vehicle fueling stations that provide ample refueling opportunities, thus permitting an operator to carry less fuel than might be required to complete a route. Exemplary embodiments of the present disclosure balance initial fuel loading and fuel stops to optimize the amount of freight weight that can be carried for a given route. The benefit is increased freight efficiency in transporting cargo from source to destination while maintaining drivability.

摘要： A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.
