The invention discloses a commercial vehicle hill-start assisting system based on electric control air pressure braking, and a control method thereof. The system comprises a system controller, a firstbrake air chamber, a second brake air chamber, a first ABS electromagnetic valve, a second ABS electromagnetic valve, a proportional relay electromagnetic valve, a first pressure sensor, a second pressure sensor, a third pressure sensor, a first wheel speed sensor, a second wheel speed sensor, a foot valve, an air cylinder, a system switch and a whole vehicle CAN and pressurization channel. The control method comprises the steps of activating the state, judging whether the vehicle state and the brake pressure reach target values or not, taking corresponding actions, judging the brake action of personnel, entering an early warning state and a pressure relief mode and the like. According to the system and the control method, on the premise that the corresponding hill-start assisting effectis achieved, it can be guaranteed that no hardware cost is increased.
