SYSTEM FOR INDICATING, RECORDING, AND EVALUATING DRIVING DATA MODE OF VEHICLE FOR FUEL ECONOMY

摘要

A system for indicating, recording and evaluating a driving-data mode underthree conditions of acceleration, speed maintenance and deceleration, in whichthe evaluated results (88) are displayed on an LCD so that the vehicle isdriven at a 3/4 point (82) of engine load capacity, serving as an accelerationpoint representing the maximum efficiency in designing a vehicle engine, at a1/5 point (84) of engine load capacity, serving as a static load point , andat a fuel-cutting point (86), thereby allowing the vehicle to be driven at themaximum efficiency point and maximizing a fuel efficiency. The system includesa fuel-injection amount-detecting unit, a maximum point-assigning unit, anengine idle driving fuel-injection amount driving point-assigning unit, 3/4and 1/5 point-assigning units, a fuel-injection amount cutting point-assigningunit, a fuel-injection amount display-indicating unit, a fuel-injection amountgraph-regulating unit, and a liquid crystal display unit.
