Abstract: The electro-mechanical brake (EMB) system use a highly integrated architecture, can reduce the number of components, enhance space utilization, optimize braking performance, and is easily integrable with other vehicle electronic control functions. It has become a hot topic in brakeby-wire research. This paper first introduces the composition and characteristics of the pneumatic brake system and EMB system for commercial vehicle platforms. It then analyzes the differences between the two systems, concluding that the EMB system offers advantages in environmental friendliness, efficiency, safety, lightweight design, and intelligence during its application in commercial vehicles. At the same time, the paper outlines challenges faced by the EMB system in its promotion, such as system instability, high cost, difficulty in standardization, and limitations in vehicle compatibility. The final solution is proposed to provide guidance for the further development of the system in the commercial vehicle field.
