A METHOD FOR CONTROLLING DAMPER CLUTCH OF A CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PURPOSE: A damper clutch control method of an infinitely variable speed change device is provided to change a condition for releasing a damper clutch when introducing into a throttle off state, thereby reducing the rocking and shock of an engine and improving the driving performance. CONSTITUTION: A damper clutch control method of an infinitely variable speed change device includes the steps of determining whether a change ratio of a throttle valve opening degree is higher than a set change ratio when the damper clutch is operating(S210,S220), determining whether a release condition is satisfied if yes(S230-S250), and releasing the damper clutch if yes, wherein the release condition is satisfied when a road inclination is higher than a set value(S270), an engine rpm is higher than a first set value, and a vehicle speed is lower than a set value.
