A vehicle brake control system, wherein a first gas port (11) of a relay valve (1) is connected to an air cylinder (5) by means of a distribution valve (2), and a second gas port (12) of the relay valve is connected to a brake pipe (6) by means of a switch structure. A third gas port (13) of the relay valve is connected to the air cylinder (5), and a fourth air port (14) of the relay valve is connected to a brake cylinder (7). A conversion device (4) is connected to the distribution valve (2). The conversion device (4) is connected to the switch structure (3). When the conversion device (4) is in different gears, the distribution valve (2) introduces gases having different pressure to the first gas port (11) of the relay valve, and controls the switch structure (3) to introduce gases having different pressure to the second gas port (12) of the relay valve, such that the relay valve (1) controls, under the action of the distribution valve (2) and the switch structure (3), the pressure of gases which come from the air cylinder (5) and circulate between the third gas port (13) of the relay valve and the fourth gas port (14) of the relay valve, and introduces gases having different pressure into the brake cylinder (7). Therefore, the vehicle can meet the braking requirements on two different lines. A vehicle and a train are also provided.
