Product-grade Prototype Development Supporting Self-defined EMB (Electromechanical Brake System) Control Software
As vehicle architectures evolve deeply toward centralized and zonal orientations, high-level autonomous driving at L4 and above imposes stringent requirements on actuators: fast response, minimalist architecture and precise pressure control. As the commanding height of next-generation braking technology, EMB (Electromechanical Brake System) completely abandons hydraulic lines and brake fluid, achieving pure brake-by-wire through motor-direct-driven calipers, with an ultimate decoupling of "four-wheel independence and millisecond-level response." Innovation in EMB control software, especially clamping-force closed-loop control and redundancy strategies, has become the core for OEMs to define differentiated intelligent driving experiences. To help OEMs and system integrators master this core IP and bridge the gap from algorithm validation to product deployment, Huahai Technology has launched the RapidECU-B1 product-grade rapid prototyping development platform for pure brake-by-wire control units, supporting forward development of self-owned software and seamless transition to mass-production readiness.
