The invention provides a power couple for a parallel hybrid electric vehicle and a control method of the power coupler. The power coupler comprises an engine output shaft gear, an engine transmission gear set, an engine connecting shaft gear, an engine transmission clutch, a volute spiral spring energy storage mechanism, a driving motor connecting shaft, a driving motor transmission clutch, a driving motor connecting shaft gear, a driving motor transmission gear set, a driving motor output shaft gear and an engine connecting shaft, wherein the volute spiral spring energy storage mechanism comprises a reversible ratchet mechanism, a planet carrier, a sun gear, a gear ring, a planet carrier brake, an energy storage mechanism output disc, a sun gear brake, a volute spiral spring, a sun gear clutch and a planet carrier clutch. According to the power couple provided by the invention, the volute spiral spring energy storage mechanism is utilized for achieving a driving start-stop function of an engine, so that energy consumption and pollution emission are reduced, and the vehicle brake energy recovery capability is improved.
