The system comprises a pneumatic pressure supply pipe (MBP), a generator (2) for generating a vehicle load signal, a weighting system (WA) designed to supply a weighted pressure which defines a maximum braking pressure, limited as a function of the load signal, and braking control units (BCA1,... BCAN) connected to the weighting system (WA) and comprising a relay valve (RV) connected between the pipe (MBP) and at least one brake cylinder (BC1,... BCN), to cause the application to this cylinder (BC1,... BCN) of a controllable braking pressure, equal to or less than the weighted pressure. The weighting system (WA) comprises an electro-pneumatic drive assembly (EPDA), which is interposed between the pipe (MBP) and the drive inlet (d) of the relay valve (RV) and is connected to the pipe (MBP) through a pressure limiter (3), and an electronic weighting control unit (WCU) which controls this drive assembly (EPDA) as a function of the load signal, so as to modulate in predetermined ways the pressure at the drive inlet (d) of the relay valve (RV). |
