Abstract:
A method for learning a touch point of an engine clutch for a hybrid electric vehicle includes controlling a speed of an engine to have an idle speed. A fluid pipe of a clutch actuator is refilled with a working fluid by driving a driving motor in an idle control state of the engine, a speed of the driving motor is synchronized with the speed of the engine, and then the engine clutch is engaged. The engine clutch is released after the refill is performed, and the speed of the driving motor is decreased. A working fluid is applied so that the engine clutch is operated in an engagement direction by operating the clutch actuator, and a state change of the driving motor is detected. The touch point of the engine clutch is determined based on the state change of the driving motor.
