The present invention relates to a method and an apparatus for controlling cleaning of an exhaust-gas recirculation (EGR) valve of a hybrid vehicle. According to an embodiment of the present invention, a method for controlling cleaning of an EGR valve of a hybrid vehicle comprises: a first determination step (S100) determining whether a drive mode of the vehicle is a hybrid drive mode by a hybrid control unit (HCU); an engine stop step (S200) of stopping the drive of an engine when the hybrid drive mode is determined in the first determination step (S100); a first learning step (S300) of measuring the amount of soot deposited on the inlet of the EGR and temporarily storing a measurement value after the engine stop step (S200); a second determination step (S400) determining whether the temporarily stored measurement value is more than a pre-stored soot deposition amount reference value after the first learning step (S300); and a second learning step (S500) of opening and closing the EGR valve multiple times and measuring and storing the amount of soot deposited on the EGR valve when determining the measurement value of the second determination step (S400), which is more than pre-stored soot deposition amount reference value, in the second determination step (S400). According to the present invention, soot deposited on an inflow path of the EGR valve can be removed while securing silence when driving a diesel-hybrid vehicle, thereby maintaining an optimum engine combustion condition of the diesel-hybrid vehicle. |
