The invention discloses an automatic returning device and method for automobile parking. The automatic returning device comprises a control panel, a steering wheel torque/angle sensor, a CKP/CMP sensor, a gear sensor, a steering transmission shaft, a planetary gear mechanism, a rotating air cylinder, a worm and an electromagnetic reversing valve. The planetary gear mechanism is respectively in driving connection with the steering transmission shaft and the worm; one end of the worm is fixedly connected with the end part of a piston rod of the rotating air cylinder; the rotating air cylinder is connected with the inner side of the throttle valve through an electromagnetic directional valve; the control panel is connected with the steering wheel torque/angle sensor, the CKP/CMP sensor, the gear sensor and the electromagnetic reversing valve. The method comprises the steps of determining that a gear is a parking gear and a vehicle is in a flameout state, and enabling the engine air inlet pipe to drive the rotating air cylinder to drive the worm to rotate through negative pressure, and completing returning. The steering wheel can return after parking, the influence of non-returning on automobile parts is effectively avoided, lateral scraping during starting is avoided, and the device can also be used as a power-assisted steering device in the driving process.
