Abstract
A method for controlling a hydraulic pressure refilling operation for an engine clutch of a vehicle includes determining whether the vehicle travels using power of a driving motor with an engine clutch maintained in a disengaged state, and upon determining that the vehicle travels using power of the driving motor with the engine clutch maintained in the disengaged state, determining whether loss of hydraulic pressure has occurred, and upon determining that loss of hydraulic pressure has occurred, controlling a hydraulic pressure refilling operation such that working fluid in a reservoir is supplied to the actuator with the engine clutch in an engaged state, and controlling the driving motor so that the driving motor outputs a compensated torque by compensating for an effect of a load torque, generated by a non-operating engine, on a torque of the driving motor.
