The invention relates to the field of commercial vehicle brake, and discloses a commercial vehicle brake disc high-temperature alarm system and alarm method based on an ECAS electric control air suspension. The system comprises an electric control air suspension module and a signal acquisition module, the electric control air suspension module comprises an electric control unit and a height sensor, and the signal acquisition module comprises a vehicle speed signal acquisition module, an environment temperature acquisition module and a vehicle body height acquisition module, a heating algorithmcalculation model and a cooling algorithm model are integrated in the electric control unit, and the current temperature of the brake disc is simulated and judged through calculation of temperature rise and temperature drop, so that high-temperature alarm is performed, and the driving safety is greatly improved. The temperature of the brake disc is calculated and detected in real time through algorithm design, when the calculated temperature of the brake disc is larger than a certain threshold value, an alarm is given through instrument display or other modes, a driver is reminded that the temperature of the brake disc is too high, and the mode has the advantages of being simple in device, high in universality, low in cost and the like.
