Electro-Mechanical Brake (EMB) systems suitable for passenger cars and commercial vehicles

Industry Trends

The automotive industry is rapidly shifting from traditional hydraulic braking systems to electro-mechanical brake (EMB) systems, driven by the development of L3+ autonomous driving.

EMB systems enable higher control precision, faster response, and improved safety, making them a key component in next-generation brake-by-wire architectures.

With the advancement of chassis domain control, EMB systems play a central role in coordinating longitudinal, lateral, and vertical vehicle dynamics, supporting the evolution of intelligent chassis ecosystems.

Functional safety and cybersecurity have become critical requirements, driving EMB systems toward redundant architectures and advanced safety design, fully aligned with ASIL-D standards.
