The invention provides an automobile, a parking system and a control method thereof. The parking system comprises an automobile stability control module, a gear control module and an electronic parking executing mechanism; the automobile stability control module is in signal connection with the electronic parking executing mechanism, and the automobile stability control module is in signal connection with the gear control module; the automobile stability control module can receive gear shifting information of the gear control module and control the electronic parking executing mechanism to beswitched between a pull-up state and a release state according to the gear shifting information. According to the parking system and the control method thereof, when the parking system and the controlmethod thereof are used, the electronic parking executing mechanism can be controlled to be switched between the pull-up state and the release state only by operating a gear shifting rod, so that parking and release of a vehicle are achieved; compared with the prior art, the steps of P-gear parking can be greatly simplified; and as the P-gear parking actuating mechanism is not involved, the P-gear parking actuating mechanism can be canceled, the internal structure of the vehicle body is simplified, and the space is saved.
