Abstract

PURPOSE: To indicate an appropriate gear ratio to instruct economic fuel consumption running, by comparing and indicating the signals of the rotational frequency of an engine and the depression of an accelerator pedal.
CONSTITUTION: The potential on the neutral part of an electricity generator is applied to a terminal 1. Potential proportional to the depression of an accelerator pedal is applied to a terminal 3. The signal from the terminal 1 is changed into a voltage by a converter 1a. The voltage is compared with a constant 1b by a comparator 1c. Said signal is also applied to a characteristic converter 2 and compared with the signal from the terminal 3 by a comparator 1c. The signal from the terminal 3 is also compared with a constant 3a by a comparator 3b. Signals from the comparators 1c, 2c, 3c are supplied to an AND circuit 4 to turn on or off indicator lamps 5, 6 to display whether the rotational frequency of an engine and the depression of the accelerator pedal are appropriate or not. Economic fuel consumption running is thus enabled.
