汽车行业深度报告：EMB线控制动是发展智能底盘、实现主动安全的关键基础，2026有望迎来量产元年

Investment Rating - The report maintains a "Positive" investment rating for the industry [6] Core Insights - The EMB (Electro-Mechanical Brake) system is identified as a key foundation for developing intelligent chassis and achieving active safety in vehicles, with mass production expected to begin in 2026 [1][3] - The EMB system features a decoupled hardware and software architecture, eliminating components like the iBooster and hydraulic lines, allowing for direct control of braking force at the wheel hub, which meets the rapid and precise braking demands of Advanced Driver Assistance Systems (ADAS) [3][4] - The domestic EMB market is projected to grow at a CAGR of over 70% from 2026 to 2030, with an expected market size exceeding 11.5 billion yuan by 2030 [4][48] Summary by Sections 1. Overview of Brake Technology Development - Traditional fuel vehicles used vacuum boosters for braking, which are expected to be phased out due to their complexity and slow response times [10] - The transition to electric vehicles has led to the adoption of electric vacuum pumps, but they have not been widely accepted due to issues like noise and short lifespan [11] - In the era of intelligent and connected vehicles, both EHB (Electro-Hydraulic Brake) and EMB systems are expected to develop concurrently, with EMB being more suitable for future intelligent chassis technology [13][14] 2. Introduction to EMB Line Control Braking - EMB achieves soft and hard decoupling by directly controlling the braking force at each wheel through electrical signals, enhancing response time and efficiency [27] - The EMB system includes electronic brake calipers, controllers, and various sensors, making it the control center for multiple safety algorithms [27] - The commercial application of EMB in commercial vehicles is anticipated to be faster than in passenger vehicles due to higher demands for braking performance and safety [37] 3. Market Size and Growth Potential - The EMB market is expected to see significant growth, with projections indicating a market size of over 11.5 billion yuan by 2030, driven by the rapid development of intelligent connected vehicles [48][51] - The report outlines a detailed forecast for EMB penetration rates, estimating a market size of approximately 1.42 billion yuan in 2026, with a projected CAGR of over 70% from 2026 to 2030 [51][52] 4. Participating Companies - Several domestic companies are accelerating their layout in the EMB market, with mass production timelines generally targeting 2025-2026 [52] - Key players include traditional brake system manufacturers like Bosch and Continental, as well as domestic firms such as Berteli and Asia-Pacific Co., which are preparing for mass production [52][54] - Startups like Coordinate Systems and Huasheng Ruili are also making strides, with some already achieving prototype development and testing [53][54]
