System And Method Of Determining Freight/Load Distribution For Multiple Vehicles
US Patent:
2012023, Sep 20, 2012
Filed:
Jan 12, 2012
Appl. No.:
13/349557

Assignee:
CUMMINS INTELLECTUAL PROPERTY, INC. - Minneapolis MN
International Classification:
G06Q 50/28
US Classification:
705338
Abstract:
Systems and methods of vehicle freight/load distribution are provided to assist in determining optimal freight distribution. Although it is standard practice to fill each vehicle to its maximum limit, due to the non-linear nature of engine fueling maps (that is, fueling maps vary non-linearly as a function of torque and speed), the optimal distribution may not be obtained by the standard practice. Finding a solution for the optimal freight distribution may also need to account for the cost of fueling and operator costs, particularly if the situation involves multiple vehicles not filled to capacity. The benefit is increased freight efficiency in transporting cargo from source to destination amongst a fleet of vehicles.

International Classification:
B60W 10/06, B60W 10/11
US Classification:
701 53
Abstract:
This disclosure provides a thermal management system and method that can recommend operational behavior to an operator of an engine system to optimize fuel economy over a period of time in which a components of the engine system is in a warm up and/or regeneration state. In one representative embodiment, the expected temperature change of the engine component at a later time is determined based on inefficient operation of the engine, such as a transmission down shift resulting in higher engine speed and lower engine torque, and the expected temperature change of the engine component resulting from operating the engine under current conditions or expected conditions at that later time is determined. A determination is made as to whether the inefficient engine operation is the optimal operation in view of fuel economy and a recommendation is generated for the operator based if optimal operation is determined.

International Classification:
G06F 7/00
US Classification:
701 51, 701 1
Abstract:
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.

International Classification:
G06F 19/00
US Classification:
701123, 701 291, 701 325
Abstract:
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.

International Classification:
G06F 7/00
US Classification:
701 51, 701 1
Abstract:
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.
