Abstract
A method for learning an upwards friction coefficient of an engine clutch of a hybrid vehicle includes: after the engine clutch is engaged, disengaging, by a controller, the engine clutch which connects an engine with a motor or disconnects the engine from the motor; when the engine clutch is disengaged, comparing, by the controller, a temperature of the engine clutch with a threshold value; and when the temperature of the engine clutch is less than the threshold value, increasing, by the controller, a friction coefficient of the engine clutch up to a certain value.
