特徴とする燃料残量測定回路。The remaining fuel amount detection circuit 1 detects the remaining amount of fuel in the fuel tank at predetermined intervals based on the fuel level, and the control circuit for the electronic fuel injection device controls the injection amount of fuel supplied to the engine. A fuel consumption amount detection circuit 5 detects the amount of fuel consumption per predetermined time based on a fuel injection pulse having a pulse width corresponding to the amount of fuel injected. The average value of the remaining fuel amount detected by the amount detection circuit 1 at predetermined time intervals is sequentially calculated, and when receiving the output from the fuel consumption amount detection circuit 5, the average value of the remaining fuel amount immediately before receiving the output is calculated. , an arithmetic circuit 2 that sequentially calculates the remaining amount of fuel by subtracting the integrated value of fuel consumption per predetermined time from the fuel consumption amount detection circuit 5 after receiving the output, and a vehicle speed detection circuit 7 that detects the speed of the vehicle. The latest remaining fuel amount from the fuel remaining amount detection circuit 1 is compared with the average value of the remaining fuel amount or the remaining fuel amount from the calculation circuit 2, and if the difference between the two is outside the predetermined range and the vehicle speed is detected. A comparator circuit 8 that outputs a control signal when the speed of the vehicle is detected to be zero by the circuit 7; and a comparator circuit 8 that outputs a control signal when the speed of the vehicle is detected as zero by the circuit 7; The switching circuit 6 selectively supplies the output of the remaining amount detection circuit 1 to the arithmetic circuit 2, and selectively supplies the output of the fuel consumption amount detection circuit 5 to the arithmetic circuit 2 when receiving the control signal. , a remaining fuel amount measuring circuit characterized in that the calculation result from the calculation circuit 2 is used as a measurement output.
