The invention discloses a brake-by-wire system based on a commercial vehicle ABS framework. The brake-by-wire system comprises two IAEB electromagnetic relay valves, a central control unit ECU, a braking main valve, a braking air chamber, a hand brake, a parking relay valve, an ABS valve, a wheel speed sensor, a storage battery, a compressor and a dryer. A pressure sensor is arranged in the IAEB electromagnetic relay valve and used for collecting the air pressure value in the IAEB electromagnetic relay valve. The central control unit calculates whether the pressure value of the valve body can meet the automobile braking requirement or not and controls the IAEB electromagnetic relay valve to conduct dynamic pressurization or decompression, and gas with any gas pressure value is output for braking. According to the system, an air pressure value signal in the IABS valve is collected through the pressure sensor arranged in the IAEB electromagnetic relay valve, and whether the pressure value of the valve body can meet automobile braking or not is calculated through the ECU, so that dynamic pressure increasing and reducing adjustment is conducted, and automobile braking is safely and rapidly achieved.
