Patent ID: 8521409

Claim:
A continuous driving mileage calculation control system, comprising an MCU microprocessor, a continuous driving mileage digital display, a vehicle speed signal sampling circuit, an instantaneous fuel consumption signal sampling circuit and a fuel signal sampling circuit; wherein the vehicle speed signal sampling circuit, the instantaneous fuel consumption signal sampling circuit and the fuel signal sampling circuit are connected to the MCU microprocessor and input the sampling signals to the MCU microprocessor; wherein, the MCU microprocessor calculates the average fuel consumption according to the received instantaneous fuel consumption signal and the vehicle speed signal, and then calculates the continuous driving mileage according to the average fuel consumption and the current remaining fuel amount; the digital display is used for displaying the continuous driving mileage; the average fuel consumption mentioned above refers to the amount of fuel consumption per hundred kilometers between two refilling; and the remaining fuel amount mentioned above is obtained by deducting the amount of fuel consumption calculated according to the instantaneous fuel consumption signal from the amount of fuel measured right after the refilling; the refilling mentioned above means that the fuel volume measured at the time of automotive ignition is increased by more than 5 liter than the fuel volume measured upon prior shutting down, and the average fuel consumption is automatically reset right after refilling.
