Brake-by-wire will replace traditional braking systems and become the future trend, with EMB expected to be the ultimate form. However, the current maturity of EMB technology is not high, and the lack of safety redundancy is the main constraint. Its maturity level may only be at 4, while EHB is at 6 - 8. Domestic brake-by-wire suppliers are expected to capture the market through EMB, with several companies planning to launch mass-producible EMB products around 2025. The industrialization of EMB is closely related to regulations and testing progress. Current standards do not have corresponding requirements or specifications for brake-by-wire systems, and safety requirements and testing methods are relatively outdated. Establishing a new safety constraint standard system is crucial. Factors such as cost, supply chain support systems, and consumer acceptance also constrain the industrialization of EMB, requiring joint efforts from multiple stakeholders in the industry.
