Abstract:
1. A system for calculating an instantaneous fuel economy for a vehicle, the system comprising: a speed sensor configured to determine a current speed of the vehicle; an acceleration sensor configured to determine a current acceleration of the vehicle; a fuel sensor configured to determine a current fuel consumption rate of an internal combustion engine of the vehicle; a display unit; and a processor communicatively coupled with the speed sensor, the acceleration sensor and the fuel sensor and operatively coupled with the display unit, the processor configured to determine the instantaneous fuel economy of the vehicle based on information obtained from the speed sensor, the acceleration sensor, and the fuel sensor, and the processor further configured to instruct the display unit to display the instantaneous fuel economy, wherein the processor is configured to determine the instantaneous fuel economy by calculating a distance that the vehicle will travel during a future period of time, by calculating an amount of fuel that the internal combustion engine will consume during the future period of time, and by dividing the distance by the amount of fuel, and wherein the processor is configured to determine the future period of time by dividing the current speed of the vehicle by the current acceleration of the vehicle.
