1. An automatically tuning method without user interference for a clutch temperature estimation model, the tuning method comprising:
generating, by a tuning value generation module, a plurality of tuning genes;
calculating, by the tuning value generation module, a tuning value corresponding to a tuning variable by using information of each tuning gene of the plurality of tuning genes;
calculating, by an accuracy calculation module, a temperature estimation accuracy by applying the calculated tuning value to the clutch temperature estimation model;
extracting, by the accuracy calculation module, a first number of tuning genes having highest calculated accuracies among the plurality of tuning genes;
and regenerating, by a recombination module, a second number of tuning genes through recombination of the extracted first number of tuning genes with highest tuning accuracy,
wherein
regenerating the second number of tuning genes comprises:
randomly selecting a third number of tuning genes from the extracted first number of tuning genes;
extracting a tuning gene component for a randomly assigned region for each tuning gene of the third number of tuning genes; and
generating a new tuning gene by combining the extracted tuning gene components in corresponding regions.
