I agree with the PrivacyPolicy and terms and conditions of VCARSYSTEM
With the continuous advancement of ADAS/AD technologies, testing scenarios have become increasingly complex, making it crucial to improve the efficiency of controller testing, validation, and analysis. As intelligent driving progresses from L2 to L3 levels of automation, intelligent driving domain controllers are gradually replacing the driver's perception and decision-making functions. While ensuring safety, in addition to real-world driving tests on public roads, simulation testing undoubtedly provides an additional layer of protection for safety.

VCARSYSTEM's Solution

ADAS/AD HIL incorporates hardware into the test loop to emulate real-world scenarios, enabling rigorous testing of algorithms, sensors, and actuators within a safer, more controllable, and repeatable environment. It further facilitates critical testing capabilities such as fault injection, corner case validation, scenario generalization, smoke testing, and stress testing, among others. These functionalities ensure autonomous driving systems undergo comprehensive validation across diverse operating conditions and potential failure modes prior to deployment.

HIL SYSTEM

VCARSYSTEM offers Hardware-in-the-Loop (HIL) testing solutions that cover the entire scope of automotive electronics, including modules for new energy powertrain systems (BMS/VCU/MCU), automotive driving systems (ACC/LKA/AEB, etc.), chassis electronic control systems (EPS/ESP/SBW/EPB/EHB/EMB), traditional powertrain systems (EMS/TCU), as well as body electronics and intelligent cockpits. It provides comprehensive HIL testing services to help customers accelerate product launch timelines.
