徴とする燃料残量測定回路。Remaining fuel amount detection units 1 and 2 detect the remaining amount of fuel in the fuel tank every unit time based on the fuel level, and remaining fuel amount detection units 1 and 2 detect the remaining amount of fuel every unit time. A first calculation unit 3 that calculates the average value of the fuel amount every time, a vehicle speed detection unit 9 that detects the speed of the vehicle, and an average value of the remaining fuel amount from the first calculation unit 3 and the remaining fuel amount detection. Compares the latest remaining fuel amount from parts 1 and 2, and outputs a control signal when the difference between the two is outside a predetermined range and the vehicle speed detecting part 9 detects that the speed of the vehicle is zero. The amount of fuel consumed per unit time is determined based on a fuel injection pulse having a pulse width corresponding to the amount of fuel injection obtained from a comparison circuit 10 that controls the amount of fuel injected to the engine and a control circuit for an electronic fuel injection device that controls the amount of fuel injected to the engine. is controlled by the fuel consumption detection units 6 and 7 that detect the amount of fuel consumption and the control signal from the comparison circuit 10, and is calculated from the average value of the remaining fuel amount output from the first calculation unit 3 immediately before receiving the control signal. , a second calculation unit 8 that calculates the remaining fuel amount by subtracting the integrated value of the fuel consumption per unit time from the fuel consumption detection units 6 and 7 after receiving the control signal, and the comparison circuit 10 When the control signal is not supplied, the calculation result from the first calculation unit 3 is selected and output, and when the control signal is received, the calculation result from the second calculation unit 8 is controlled by the control signal from the second calculation unit 8. and a switching circuit 11 for selectively outputting the remaining fuel amount measuring circuit, characterized in that the calculation result from the first or second calculation circuit 3 or 8 selected by the switching circuit 11 is used as the measurement output. .
