The present invention relates to the technical field of trailer braking, and provides a trailer control valve and a trailer braking system. The trailer control valve includes a control port (15), a relay valve (10), an air inlet (11) and a first air outlet (12), the control port (15) being connected to a control chamber (10a) of the relay valve (10), and the air inlet (11) and the first air outlet (12) being respectively connected to a brake chamber (10b) of the relay valve (10). The trailer control valve further includes a traction control valve (20) arranged in a pipeline from the control port to the control chamber (10a) and connected to the air inlet (11). The traction control valve (20) has a first operating state in which the control port (15) is in communication with the control chamber (10a) through a first channel (20a) of the traction control valve (20). The traction control valve (20) has a second operating state in which the air inlet (11) is in communication with the control chamber (10a) through a second channel (20b) of the traction control valve (20). According to the present invention, an ordinary trailer control valve is integrated with the traction control valve (20), such that a braking force of a trailer can be actively controlled according to the state of a vehicle, realizing active control of traction of the trailer and improving the safety of the whole vehicle.
