Abstract

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.

Description

technical field [0001] The invention relates to the field of semi-trailer trains, in particular to a braking control system and method for semi-trailer trains. Background technique [0002] Because of its functions of "section transportation" and "drop-and-pull transportation", semi-trailer trains have become an important means of improving transportation efficiency and have been paid more and more attention. But braking safety is a major hidden danger of automobile trains always. [0003] Because the semi-trailer train uses air pressure braking, the braking system of the semi-trailer train currently includes a brake valve. The trailer is carried out at the same time, but because the brake pipeline of the semi-trailer is longer, the braking time of the semi-trailer is longer than that of the tractor, and the braking time of the semi-trailer is longer than that of the tractor. 0.9s), the tractor brakes earlier than the semi-trailer, the traction connection device of the sem...
