Illustrative embodiments of the disclosure relate to systems and methods for determining operational costs of vehicles. More particularly, illustrative embodiments of the disclosure relate to a vehicle operational cost display system and method which calculates the operational cost of a vehicle based on fuel cost input and displays the calculate operational cost to an operator of the vehicle.
Plug-in HEVs (hybrid electric vehicles) provide a vehicle operator with an MPGE (Distance Per Gallon Electric or Equivalent) calculation. MPGE is the industry standard but does not take into account the cost of electricity needed to charge the high capacity battery of the vehicle. The total operational cost of a PHEV (plug in hybrid electric vehicle) or extended range vehicle is not available to the vehicle operator.
Accordingly, a vehicle operational cost display system and method which calculates the operational cost of a vehicle based on fuel cost input and displays the calculate operational cost to an operator of the vehicle is needed.
Illustrative embodiments of the disclosure are generally directed to a vehicle operational cost display system which calculates the operational cost of a vehicle based on fuel cost input and displays the calculate operational cost to an operator of the vehicle. An illustrative embodiment of the system includes a user interface adapted for entry of cost of fuel for operation of a vehicle; a central processing unit interfacing with the user interface, the central processing unit having a calculator function adapted to calculate total operational cost of the vehicle based on the cost of fuel for operation of the vehicle and distance traveled; and a display interfacing with the central processing unit, the display adapted to display the total operational cost of the vehicle.
Illustrative embodiments of the disclosure are further generally directed to a vehicle operational cost display method. An illustrative embodiment of the method includes entering a fuel cost for a vehicle and calculating and displaying a total operational cost of the vehicle based on the fuel cost, distance per unit volume of fuel consumed and distance traveled by the vehicle.
Illustrative embodiments of the disclosure will now be described, by way of example, with reference to the accompanying drawings, in which:
The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments or the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable users skilled in the art to practice the disclosure and are not intended to limit the scope of the claims. Moreover, the illustrative embodiments described herein are not exhaustive and embodiments or implementations other than those which are described herein and which fall within the scope of the appended claims are possible. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

The system 100 may include a CPU (central processing unit) 102. The CPU 102 may have a calculator function 104. A user interface 106 may interface with the CPU 102. The user interface 106 may permit an operator to input the fuel cost (gasoline or diesel cost 110 and/or electricity cost 112) of the vehicle at the time of vehicle fueling such as at the beginning of a trip, for example and without limitation.
A display 114 may interface with the CPU 102. The display 114 may be adapted to indicate the battery charge cost 116, or the cost which is incurred to charge the vehicle battery such as at the beginning of and during the trip. The display 114 may also be adapted to display the distance per unit volume (such as miles per gallon, MPG 118, for example and without limitation) which has been achieved by the vehicle since the start of the trip. The display 114 may be adapted to display a total cost calculation 120, which is the total operational cost of the vehicle which accrues on the trip.
The CPU 102 may be adapted to calculate the battery charge cost 116 by multiplying the quantity of electrical power which is charged into the vehicle battery by the electricity cost 112 (cost of electricity per unit) which is input into the user interface 106 by the vehicle operator:
Battery charge cost=quantity of electrical power charged*electricity cost
The battery charge cost 116 may include the cumulative cost of charging the vehicle battery at all points throughout the trip. The CPU 102 may be adapted to calculate an MPG cost by dividing the distance traveled since the start of the trip by the distance per unit volume of fuel consumed (e.g., miles per gallon) which have been achieved by the vehicle since the start of the trip (trip MPG) and multiplying the resulting quotient by the gas cost per unit volume:
MPG cost=[Distance traveled/trip MPG]*gas cost/unit volume
The CPU 102 may be adapted to calculate the total trip cost by adding the MPG cost to the battery charge cost:
Total trip cost=MPG cost+Battery charge cost
In exemplary application of the system 100, a vehicle operator (not shown) enters the fuel cost (including the gas cost 110, such as dollars per unit volume of gasoline and the electricity cost 112, such as the cost of electricity per unit) in the user interface 106 at the beginning of a trip which is to be taken in an HEV. The CPU 102, via the calculator function 104, calculates the total cost calculation 120 such as by calculating the MPG cost, the battery charge cost and the total trip cost based on the MPG cost and the battery charge cost 120 as was set forth above. The CPU 102 displays the battery charge cost 116, the trip MPG 118 and the total cost calculation 120 on the display 114.

The system 300 may include a CPU (central processing unit) 302 having a calculator function 304 and a user interface 306. The user interface 306 may permit an operator to input the gas cost 310 of the vehicle at the time of vehicle fueling such as at the beginning of and/or during a trip, for example and without limitation.
A display 314 may interface with the CPU 302. The display 314 may be adapted to display the trip MPG (distance per unit volume such as miles per gallon of gasoline consumed) 318 which has been achieved by the vehicle since the start of the trip. The display 314 may be adapted to display a total cost calculation 320, which is the total operational cost of the vehicle which accrues on the trip.
The CPU 102 may be adapted to calculate an MPG cost by dividing the distance traveled since the start of the trip by the distance per unit volume of gasoline consumed which has been achieved by the vehicle since the start of the trip (trip MPG) and multiplying the resulting quotient by the gas cost per unit volume:
MPG cost=[Distance traveled/trip MPG]*gas cost/unit volume
The total trip cost 320 may correspond to the MPG cost.
In exemplary application of the system 300, a vehicle operator (not shown) enters the gas cost 310 (such as dollars per gallon or other unit volume) in the user interface 306 at the beginning of a trip which is to be taken in a conventional internal-combustion engine vehicle. The CPU 302, via the calculator function 304, calculates the total cost calculation 320 such as by calculating the MPG cost as was set forth above. The CPU 302 displays trip MPG 318 and the total cost calculation 320 on the display 314.
