Embodiment Construction

[0042] In conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0043] The system structure in this embodiment is as figure 1 As shown, it includes a signal acquisition circuit 1 , a signal preprocessing circuit 2 , a single chip processing circuit 3 and a display circuit 4 .

[0044] Wherein, the signal acquisition circuit 1 includes a fuel injector signal acquisition circuit 11 and a vehicle speed sensor signal acquisition circuit 12 . The fuel injector signal acquisition circuit 11 collects the pulse signal of the fuel injector by connecting to the electrode of one or more engine fuel injectors or the signal output terminal of the fuel injector. Number of oil droplets N. The output current of the pulse signal in this embodiment is 50mA, and the output voltage V p-p is 12V. Each pulse represents a drop of oil, and the oil volume per drop is 36 μL. The maximum output of this pulse signal is 500 pulse...

Abstract

The invention mainly discloses a method and a device for calculating average fuel consumption, remaining fuel and driving range. The average fuel consumption S can be worked out according to both the acquired drop number N of the fuel sprayed by a fuel spray nozzle, pulse number P of a vehicle speed signal and pulse number ppk of per kilometer vehicle speed signal and the volume SN represented by each drop of fuel. The remaining fuel deltaS can be worked out by subtracting the total amount NXSN of consumed fuel sprayed by a fuel sprayer from the total amount S of oil in an oil tank after ignition. The driving range can be worked out by dividing the remaining fuel deltaS by the average fuel consumption S. The method can help a driver to obtain accurate information on the average fuel consumption, remaining fuel and driving range of an automobile, get an idea of the running condition of the automobile and the consumption condition of the fuel and select a driving mode consuming the lest fuel, thereby saving fuel consumption and protecting environment.

Description

technical field [0001] The invention relates to the technical field of automobile accessories, in particular to a method for calculating average fuel consumption and mileage with remaining fuel. Background technique [0002] At present, the structure of the fuel tank in the automobile industry is flat and low. The fuel tank sensor adopts a float structure, and the output resistance value represents a certain amount of fuel. When the fuel tank of this structure is on different road surfaces and in different vibration states, even if the fuel tank has the same fuel volume, the resistance value output by the fuel tank sensor will be different. [0003] Usually, the average fuel consumption calculation in the industry generally adopts a relatively rough measurement method, first add a tank of fuel, then drive to consume the tank of fuel, and record the mileage traveled at the same time, so as to measure the average fuel consumption. This measurement method is very inaccurate, a...
