Abstract
A coefficient of friction correction device for a belt-type continuously variable transmission is provided in which the coefficient of friction corrector calculates a coefficient of friction correction factor from the coefficient of friction calculated by the coefficient of friction calculator for a predetermined gear ratio and the default value of the coefficient of friction stored in the coefficient of friction map for the predetermined gear ratio, and uniformly corrects the default value of the coefficient of friction stored in the coefficient of friction map for each gear ratio using the coefficient of friction correction factor. This enables the default values of the coefficient of friction of all the coefficient of friction maps to be corrected by calculating just one coefficient of friction correction factor, and enables the reliability of the corrected default value of the coefficient of friction to be ensured.
