The invention belongs to the technical field of self-control valves, and discloses a hydraulic follow-up self-control valve, a control system, a control method and a follow-up self-control jack. The control system comprises a hydraulic follow-up self-control valve, a first connector and a second connector of the hydraulic follow-up self-control valve are connected with a liquid inlet cavity and a first liquid return cavity of a follow-up hydraulic component, and a second connector of the hydraulic follow-up self-control valve is connected with a second liquid return cavity of a follow-up hydraulic component. And a third interface and a fourth interface of the hydraulic follow-up automatic control valve are respectively connected with a second liquid inlet cavity and a second liquid return cavity of the driving hydraulic component between the hydraulic control lock and the main control reversing valve. The hydraulic follow-up self-control valve control system is integrated on the jack, the hydraulic follow-up self-control valve is integrated on the jack, follow-up and self-locking functions of the follow-up jack can be achieved without manual operation, and the follow-up jack can automatically switch working conditions along with switching of working conditions of a driving hydraulic component.
