The invention discloses a brake control system for an automatic port driving container truck and a control method thereof. A brake gas supply device is used for providing compressed air for a brake system and is connected with the input terminal of a brake valve assembly through an air passage; the brake valve assembly cooperates with a brake pedal travel sensor; the output terminal of a proportional relay valve is connected with the brake gas supply device through an air passage, and the proportional relay valve is connected with an ABS electromagnetic valve; a gas transmission end of the ABSelectromagnetic valve is connected with a brake gas chamber; a wheel speed sensor is used for collecting the speed of vehicle wheels and is electrically connected with a controller and a feedback device. The proportional relay valve is calibrated, a pressure signal is fed back to a controller through a built-in pressure sensor of the proportional relay valve, the air pressure of the proportionalrelay valve is adjusted and calibrated to ensure the precision of active braking; and since mechanical transmission is replaced with an electric signal, the problem of aging of mechanical transmissionis solved.
