The invention relates to a hydraulic automatic control device of a car stopper. The device comprises a car stopper body, wherein the car stopper body is connected with a hydraulic cylinder through a connecting device; an oil pipe on the hydraulic cylinder is connected with two oil inlets in the upper side of a three-position four-way electromagnetic reversing valve; an oil inlet in the lower side of the three-position four-way electromagnetic reversing valve is communicated with an oil tank through a one-way valve, a hydraulic motor and a filter in sequence; and another oil inlet is communicated with the oil tank through a cooler. After the structure is adopted, multiple automatic control functions including car stop are realized, so that a winch control system is operated more safely and reliably, the performance is more stable, and the device has comprehensive promotion and application prospect in the mine inclined shaft rail lifting field.
