Abstract

PURPOSE:To correctly detect the remained fuel amount by outputting the up-to-date value of the remained fuel amount data only when fuel supply is detected and calculating the remained amount by the subtraction of the fuel consumption amount when engine operation state is detected. CONSTITUTION:A fuel remained amount detecting means receives the signal supplied from the liquid level detection sender of a fuel tank and calculates the remained fuel amount, and a remained fuel amount calculating means judges if an engine is in operation or not, and if the engine is in operation, a signal is output directly into the remained fuel amount calculating means, and if the engine is not in operation, a signal is output into a fuel supply judging means, and each means is energized. The remained amount calculating means detects the up-to-date value of the remained fuel amount according to the in-fuel-supply signal the supply judging means. The subtraction of the consumption amount detected by a fuel consumption amount detecting means according the the operation signal supplied from an engine state judging means is performed to calculate the remained fuel amount. Therefore, the remained amount can be detected correctly without being influenced by the variation of the situation of the car.

Conventional fuel remaining amount display devices for vehicles detect the remaining amount of fuel in the fuel tank when the ignition switch is turned on, detect the fuel consumption amount from the fuel injection signal when the engine is running, and calculate the fuel consumption from the above fuel remaining amount data. By subtracting the amount data, the remaining fuel amount at each instant was determined and displayed.

This is because when the ignition switch is turned on, that is, just before the engine starts, the liquid level in the fuel tank is stable with little fluctuation, but when the engine is running or
Considering that the liquid level inside the fuel tank fluctuates greatly while the vehicle is running, making it impossible to accurately detect the liquid level, the fuel injection signal from the engine, which can relatively accurately detect fuel consumption, is used to This is to calculate the remaining amount.

However, the posture of the vehicle when the ignition switch is turned on varies depending on the road surface condition, and is not necessarily maintained horizontally. If the vehicle is horizontal, accurate fuel remaining data can be obtained, but if the vehicle is tilted, the data obtained for the same amount of remaining fuel may vary depending on the tilt. Put it away. Therefore, if the vehicle posture when the ignition switch was last turned on is significantly different from the vehicle posture when the ignition switch is turned on this time, the display of the remaining fuel level may change significantly after the ignition switch operation. There is a problem with this.
