DISPLAY DEVICE FOR REMAINING MILEAGE OF AUTOMOBILE

PURPOSE:To give easily an average measure for remaining mileage by displaying selectively the output signals from the 1st multiplier circuit which calculates the remaining mileage with tentative fuel cost as a coefft. signal and the 2nd multiplier circuit which uses the actual fuel cost. CONSTITUTION:A remaining amt. detector 10 obtains the output signal (l) for the remaining amt. corresponding to the remaining amt. of fuel from the gauge in a fuel tank. A tentative fuel cost circuit 11 outputs the tentative fuel cost corresponding to the traveling condition as a coefft. signal (m). A multiplier circuit 12 multiples the output signal (l) and the coefft. signal (m) indicating the tentative fuel cost to calculate remaining mileage and displays the same via a display circuit 13. An arithmetic circuit 18 for actual fuel cost calculates the actual fuel cost in accordance with a vehicle speed signal and a fuel consumption signal and trnasmits and actual fuel cost signal (n). A multiplier circuit 19 multiplies and signal (n) and the signal (l) to calculate the remaining mileage. When a preset value is attained, the circuit 18 is started and the content of the circuit 19 is displayed on the circuit 13.
