China's brake industry

In the past decade, China's brake industry has undergone a profound intelligent revolution, with the core moving from traditional mechanical hydraulic drive to electronic control, digitization, and networking. In the field of rail transit, leading enterprises represented by CRRC Sifang have launched fully electric and intelligent mechanical braking systems, replacing compressed air with electric direct drive, achieving a leap in response time reduction of 40% and 100% intelligent self diagnosis of key components. In the automotive industry, the wave of electrification and intelligence has given birth to Brake by Wire technology, which achieves millisecond level response and precise single wheel control through the electronic control architecture of 'sensor ECU actuator'. It has not only become a key hardware for the landing of advanced intelligent driving, but also improved the braking energy recovery efficiency of new energy vehicles by up to 17%. This revolution also deeply penetrated into the manufacturing process, by introducing robots, vision systems, and online inspection, a highly automated intelligent production line was built, which increased the first-time inspection pass rate to over 90% and significantly reduced labor costs. In high-precision fields such as aviation, the industry is committed to building a forward research and development system for model-based systems engineering (MBSE) and promoting the construction of 'digital intelligent braking'. Overall, intelligence has reshaped the entire value chain from product design, production and manufacturing to operation and maintenance services, upgrading the braking system from a secure execution component to a smart core that empowers intelligent travel and green transportation.
