System for indicating, recording and evaluating driving data mode of vehicle for fuel economy
First Claim
1. A system for indicating, recording and evaluating a driving-data mode of a vehicle for fuel economy, comprising:
- a fuel-injection amount-detecting unit for detecting a digital signal converted from an analog signal determining a fuel-injection amount;
a maximum point-assigning unit for assigning the maximum point of the fuel-injection amount;
an engine idle driving fuel-injection amount driving point-assigning unit for assigning a driving point having a fuel-injection amount for engine idle driving;
a ¾
point-assigning unit for assigning a point to be ¾
of a distance from the driving point having the fuel-injection amount for engine idle driving to the maximum point of the fuel-injection amount;
a ⅕
point-assigning unit for assigning a point to be ⅕
of the distance from the driving point having the fuel-injection amount for engine idle driving to the maximum point of the fuel-injection amount;
a fuel-injection amount cutting point-assigning unit for assigning a point for cutting off the fuel-injection amount;
a fuel-injection amount display-indicating unit for indicating the display of the fuel-injection amount and recording the display for a designated period;
a fuel-injection amount graph-regulating unit for finely regulating a graph illustrating the fuel-injection amount; and
a liquid crystal display unit for displaying obtained results, wherein variables of the assigning units are set.

Abstract
A system for indicating, recording and evaluating a driving-data mode under three conditions of acceleration, speed maintenance and deceleration, in which the evaluated results are displayed on an LCD so that the vehicle is driven at a ¾ point of engine load capacity, serving as an acceleration point representing the maximum efficiency in designing a vehicle engine, at a ⅕ point of engine load capacity, serving as a static load point, and at a fuel-cutting point, thereby allowing the vehicle to be driven at the maximum efficiency point and maximizing a fuel efficiency. The system includes a fuel-injection amount-detecting unit, a maximum point-assigning unit, an engine idle driving fuel-injection amount driving point-assigning unit, ¾ and ⅕ point-assigning units, a fuel-injection amount cutting point-assigning unit, a fuel-injection amount display-indicating unit, a fuel-injection amount graph-regulating unit, and a liquid crystal display unit.
