Automatic gear shifting determination apparatus and method using gradient determination of road using fuzzy

摘要

The present invention relates to a method for determining an automatic shift by determining the gradient of a road using fuzzy logic, and more particularly, to an automatic transmission determining method for determining an automatic transmission, Implementation of road gradient algorithm by fuzzy clustering and estimation of gradient by fuzzy inference in order to estimate the gradient of road during driving using vehicle speed, acceleration, throttle opening, (S300) of determining an optimum shift stage by calculating a fuzzy inference and a step of determining an optimum shift stage by a fuzzy inference method (S300).
