Abstract:
A method and system for remotely determining real-time operating fuel efficiencies based on dynamic operating characteristics of a vehicle to generate an optimal refueling management approach for the vehicle by providing refueling locations and associated refueling amounts for each refueling location, to achieve improved vehicle fuel economy, is provided.
Abstract:
An apparatus remotely provides refueling management instructions for a vehicle. One or more initial vehicle parameters are determined, including an initial quantity of fuel, a plurality of route parameters including a starting point, an ending point and an estimated average fuel efficiency of the vehicle, and a plurality of refueling parameters including one or more refueling locations. The sufficiency of an initial quantity of fuel is evaluated in relation to the estimated average fuel efficiency and a distance to be traveled by the vehicle equal to a difference between the ending point and the starting point. One or more current vehicle parameters are interpreted at a first predetermined time, a refueling agenda is created, and an associated predetermined refueling amount at each of the identified one or more refueling locations is determined.
Abstract:
Controlling a speed of a vehicle based on at least a portion of a route grade and a route distance divided into a plurality of route sections, each including at least one of a section grade and section length. Controlling the speed of the vehicle is further based on determining a cruise control speed mode for the vehicle for each of the plurality of route sections and determining a speed reference command of the vehicle based on at least one of the cruise control speed mode, the section length, the section grade, and a current speed.

Abstract:
Apparatuses, methods and systems including dynamic estimations of vehicle mass and road grade estimation are disclosed. One exemplary embodiment is a method including operating a vehicle system to propel a vehicle, determining with a controller a vehicle mass estimate and an uncertainty of the vehicle mass estimate, evaluating with the controller the uncertainty of the vehicle mass estimate relative to at least one criterion, if the uncertainty of the vehicle mass estimate satisfies the criterion, determining with the controller a road grade estimate, and controlling with the controller utilizing the road grade estimate at least one of a vehicle speed and an engine output.

Abstract:
A vehicle may include a controller configured to control the vehicle to operate in an active control mode or a passive control mode. In the passive control mode, the controller may provide a feedback indicator on a human machine interface. In the active control mode, the controller may provide a control command to an engine control unit.
