The invention relates to the field of a semi-trailer train, in particular to a brake control system and method for the semi-trailer train. The brake control system for the semi-trailer train comprises an air braking system, a controller ECU (Electronic Control Unit) and a vehicle condition monitoring system; the air braking system comprises an energy supply module, a tractor braking module and a trailer braking module; the energy supply module comprises an air compressor, a standby air source, a pressure regulating valve and a three-loop protection valve; the tractor braking module comprises a tractor front-axis gas storage barrel, a tractor rear-axis air storage barrel; a brake proportional valve, a first two-position two-way electromagnetic valve, a tractor front-axis brake air chamber, a tractor rear-axis brake air chamber, a first air pressure sensor and a second air pressure sensor; the trailer braking module comprises a trailer air storage barrel, a second two-position two-way electromagnetic valve, an electrical control proportional valve, a trailer brake air chamber and a third air pressure sensor. According to the system, a braking pressure on a tractor and a trailer is regulated in real time; meanwhile, the problem of delay of trailer braking is solved; brake safety of the semi-trailer train is improved.
