The invention provides a parking control system, a gearbox and an automobile, and relates to the technical field of automobiles. The parking control system comprises a first oil path for communicatinga main oil path and a parking valve control port, and the first oil path is provided with a parking control valve for controlling a parking valve; a parking liquid outlet communicates with an oil tank and a valve core control port oil way of the parking valve correspondingly; a parking switching valve is arranged between the parking liquid outlet of the parking control valve and the oil tank, andwhen the automobile is in a parking state, the parking switching valve controls the parking liquid outlet to communicate with the oil tank; the parking control system comprises a second oil path forcommunicating a main oil path and a clutch, and a clutch control valve is arranged on the second oil path; and the clutch liquid outlet communicates with a switching control port of the clutch and theparking switching valve, and when the automobile is in the parking state, the clutch control valve controls the clutch liquid inlet and the clutch liquid outlet to be disconnected.
Description
Technical field [0001] The present invention relates to the field of automobile technology, in particular to a parking control system, a gearbox and an automobile. Background technique [0002] In the prior art, when the parking gear is released, after the parking solenoid valve and the clutch solenoid valve are opened simultaneously, the hydraulic oil in the main oil circuit enters the clutch control valve and the parking control valve at the same time, causing the clutch to not be engaged When in place, the parking control valve controls the movement of the spool of the parking valve, thereby unlocking the parking gear of the car. Because the clutch is not in place at this time, the speed of the transmission components in the gearbox cannot be determined, and the transmission ratio of the gearbox cannot be determined. If the parking valve is unlocked at the same time, the car will move forward at an uncertain speed, affecting driving. Experience. Summary of the invention [00...
