Introduction
RCP and HIL are real-time simulation technologies for controller development, but their application scenarios differ. RCP is a fake controller + a real controlled object, while HIL is a real controller + a fake controlled object. In RCP, the control algorithm runs on real-time hardware, controlling real objects; in HIL, the controller is real, but the controlled object is virtual.
The ADAS domain controller is the core computing unit of intelligent driving systems, integrating data from multiple sensors (cameras, radar, LiDAR, etc.) to achieve perception, decision-making, and control functions (such as AEB, ACC, LKA, etc.). Rapid prototyping development through RCP and HIL testing ensures that the control system meets functional safety (ISO 26262) and performance requirements.
How to choose a suitable real-time machine?
Choosing a stable and reliable real-time machine (RCP & HIL) that has been widely used in the industry requires several important considerations:
1) A professional and reliable host computer software platform (no crashes or freezes);
2) Good product scalability, consistent compatibility of I/O modules (hardware and software from the same company, as cobbled systems can lead to instability).

PART.2
ADAS HIL System
After the ADAS domain control hardware (the physical prototype of the final mass-produced domain controller) is completed, a high-fidelity real-time simulation system simulates vehicle dynamics, sensor environments, and road scenarios, connecting the domain control hardware to the simulation closed-loop for testing the ADAS control system. This is a critical verification step from development to mass production for the domain controller.
HIL testing of the real controller includes autonomous driving and ADAS controllers. By integrating multiple HIL systems, real-time data interaction is conducted to test various complex scenarios and simulate fault conditions between ECUs and sensors. Using AND’s reflective memory technology (Multi-node), large-capacity data (8 Gbps) bandwidth can be achieved, along with a synchronization mechanism for real-time data interaction between multiple systems.
AND’s high-performance real-time simulation system supports running vehicle dynamics models (such as CarSim, Carmaker), sensor models (millimeter-wave radar, LiDAR), and combines the vehicle’s three electric HIL system models (MCU, VCU, and BMS) to generate simulation data in real-time, efficiently conducting vehicle-level system testing.
AND’s real-time machine integrates multiple HIL systems with actual test benches, reproducing real driving phenomena while testing actual electronic control units on the test bench.
Below is the vehicle-level ADAS hardware-in-the-loop testing (iTest software) conducted by the China Automotive Research Institute.
RCP and HIL are indispensable technical means in the development of ADAS domain control: RCP lays the foundation for subsequent development by quickly prototyping and verifying algorithm feasibility; HIL comprehensively verifies the integration performance and reliability of the domain controller through hardware-in-the-loop testing, ensuring it meets functional safety and mass production requirements. The combination of both significantly reduces development risks and shortens cycles, serving as a key verification node in the modern automotive electronics development “V model.” As ADAS evolves towards higher levels of autonomous driving, the real-time performance, simulation accuracy, and automation of RCP and HIL will further improve to meet more complex scenarios and higher safety requirements.
