Introduction
As vehicle architecture evolves deeply toward centralized and zonal orientation, L4 and higher-level autonomous driving imposes stringent requirements on actuators for fast response, minimalist architecture and precise pressure control. As the high ground of next-generation braking technology, EMB (electromechanical brake system) completely eliminates hydraulic lines and brake fluid, achieving pure x-by-wire through motor direct-drive calipers and attaining the 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 automakers to define differentiated intelligent driving experiences. To help automakers and system integrators master this core IP and bridge the gap from algorithm verification to product deployment, Huahai Technology has launched the RapidECU-B1 pure brake-by-wire control unit product-level rapid prototyping platform, supporting forward-looking proprietary software R&D and seamless connection to mass production.

Functional Features
The RapidECU-B1 product-level rapid prototyping platform is specifically designed for the high real-time performance, high-power actuation, and high safety-integrity requirements of electro-mechanical brake (EMB) systems, and consists of the following four core components:

(1) ECUCoder automatic code generation tool: supports MATLAB\Simulink modeling, graphical configuration of basic software, and one-click fully automatic code generation without writing a single line of code;

(2) MeCa measurement & calibration tool: supports CCP\XCP calibration protocols, real-time online measurement and calibration, and program flashing;

(3) RapidECU-B1 hardware platform: integrates the control unit module, brake sensor module, and actuator modules such as the BLDC motor and solenoid valves;

(4) Other related accessories such as communication adapters and wiring harnesses.


Advantages of the plan

• Supports customer-defined brake-by-wire software development;

• Easy to use: adopts model-based graphical modeling software development and automatic code generation technology, no manual programming required;

• Equipped with the new-generation 32-bit dual-core S32K3 series functional-safety high-performance dual-core processor, with a functional safety level up to ASIL-D;

• Supports 3-channel high-speed CAN FD communication, and supports hard-wired wake-up and CAN wake-up;

• The control module is replaced on the basis of mass-production components, with automotive-grade hardware design that is robust, durable and highly reliable;

• Program flashing supports A/B partition backup and an abnormal-program rollback mechanism, making development more convenient;

• Can replace expensive PC control prototypes, suitable for prototype, trial-production and small-batch stages.
