Abstract

PURPOSE: To simplify the detecting unit and a calulating circuit by preparing the time width signals indicative of a unit fuel cost from the signals which are proportional to the depression of an accelerator.
CONSTITUTION: A signal producing circuit 1 generates the time width signals for a unit fuel cost, and the signals are converted into calculating signals as at 2. On the other hand, pulses are generated as at 3 in accordance with the running distance, and the gate 3 is controlled by the converting circuit 2 to allow the running distance signals 3 to pass. If the output of the gate 3 is counted as at 4, the counted value becomes the running distance for the unit fuel cost. The fuel cost thus calculated is latched as at 6 for one period and is digitally displayed as at 7. Thus, it is possible to simplify the calculating circuit which is used to detect the electric signals proportional to the fuel consumption and the calculate the fuel cost.
