Group 1: Technology Overview - The article introduces the concept of line control braking technology, which has recently received approval from national standards, paving the way for its implementation in vehicles [6][27]. - Current systems like EHB (Electronic Hydraulic Brake) still rely on hydraulic components, while EMB aims to eliminate these, using electric motors at each wheel for direct control [9][12]. - EMB technology promises faster response times, potentially reducing braking distances significantly compared to traditional systems [12][13]. Group 2: Benefits of EMB - EMB offers three main advantages: speed, precision, and efficiency. It can reduce response times to under 100ms, which is crucial for advanced driving assistance systems [12][14]. - The precision of EMB allows for individual wheel control, enhancing vehicle stability and safety, especially in adverse conditions [18]. - By eliminating the hydraulic system, EMB reduces vehicle weight and maintenance costs, contributing to better fuel efficiency and longevity of components [20][21]. Group 3: Market Readiness and Challenges - Despite the technological readiness, EMB has seen limited adoption in the market, with only a few models currently utilizing this system [23][24]. - Safety concerns remain a significant barrier to widespread implementation, as the automotive industry prioritizes reliability in braking systems [25]. - The introduction of national standards (GB 21670-2025) aims to address safety and redundancy requirements for EMB, but this may increase production costs by 30%-50% compared to existing systems [29][30]. Group 4: Future Outlook - The article suggests that while EMB technology is not yet fully mature, it is at a critical juncture for potential market expansion, with major suppliers preparing to launch products [31][34]. - Domestic suppliers are also advancing in this field, indicating a competitive landscape for EMB technology development [32][34]. - The expectation is that major automotive manufacturers will begin to adopt EMB systems in the near future, signaling a shift in braking technology [35].
