The present invention relates to the technical field of trailer control, and provides a trailer control valve and a trailer control system. The trailer control valve comprises: a relay piston and a balance piston arranged in a first chamber of the relay piston, two end faces of the relay piston being respectively in communication with a control port and located in a brake chamber, the balance piston being connected to a bottom wall of the first chamber via a predominance spring, and there being a space, which is in communication with brake chamber, between the balance piston and a top wall of the first chamber; an adjusting piston arranged in a second chamber of the relay piston, extending into the first chamber and directly facing a valve port of the balance piston; and a predominance adjusting port in communication with the second chamber, wherein as an air pressure at the predominance adjusting port changes, the adjusting piston is pushed to change a distance from the valve port, such that an air pressure predominance of an air outlet relative to the control port changes. In the present invention, the use of the adjusting piston can automatically adjust the air pressure predominance of the trailer control valve as the air pressure at the predominance adjusting port changes, so as to increase the consistency of the braking of a tractor and a trailer, thereby improving the safety performance of the vehicle.
