A signal representing the operating parameter of the internal combustion engine of the running vehicle measured in terms of the amount of fuel being consumed by the vehicle and another signal representing the running speed of the vehicle are separately integrated by first and second integrating circuits, whereby when the integrated value of the first integrating circuit reaches a predetermined value, the integrated value of the second integrating circuit is indicated.

Abstract: Indication of possible vehicle running distance with remnant fuel is accomplished by measuring the fuel amount, the fuel consumption and the running distance and calculating the possible remaining running distance with remnant fuel. The indication is directly based on the current driving condition so that the driver can know the possible running distance with remnant fuel in continued driving under similar conditions. The indication can prevent fuel shortage and also teach a driver economic driving.
