INSTANTANEOUS FUEL CONSUMPTION DISPLAYING DEVICE FOR VEHICLE
First Claim
1. An instantaneous fuel consumption displaying device for a vehicle comprising:
- fuel injecting means for injecting fuel into an engine in response to an injection pulse inputted thereto;
injection controlling means for supplying an injection pulse corresponding to an amount of injected fuel calculated based on an operational situation of said engine to said fuel injecting means, and forming information on the amount of injected fuel in accordance with the number of injection pulses supplied to said fuel injecting means;
display controlling means for calculating an instantaneous fuel consumption based on the information on the amount of injected fuel, and displaying information on the instantaneous fuel consumption thus calculated on a display portion; and
a communication line through which the information on the amount of injected fuel is transmitted from said injection controlling means to said display controlling means;
wherein said instantaneous fuel consumption displaying device for a vehicle includes the information on the amount of injected fuel composed of a plurality of fuel consumption signals, the injection controlling means adds time information to the plurality of fuel consumption signals and sends out the resulting information whenever the number of injection pulses becomes a value corresponding to a predetermined reference instantaneous injection amount, and said display controlling means, while receiving the plurality of fuel signals in order, determines whether or not the fuel signal thus received is a predetermined signal, and when the plurality of fuel consumption signals are discriminated by the reference number decides that the fuel for the reference instantaneous injection amount is injected to calculate the instantaneous fuel consumption, thereby displaying information on the instantaneous fuel consumption.

Abstract
An injection valve injects a given amount of fuel into an engine in response to an injection pulse. An ECU inputs the injection pulse corresponding to an amount of injected fuel. The ECU inputs information on an amount of injected fuel corresponding to the number of injection pulses to a display controlling portion through a communication line. The ECU produces the information on the amount of injected fuel composed of digital data whenever a given number of injection pulses corresponds to the given amount of fuel. The display controlling portion decides that the given amount of fuel is injected from the injection valve when a predetermined number of pieces of digital data are properly received. The display controlling portion calculates an instantaneous fuel consumption based on an amount of injected fuel thus decided and an operating distance to cause a meter to display information on the instantaneous fuel consumption.
