With the continuous advancement of ADAS/AD technology, testing scenarios are becoming increasingly complex, making it crucial to enhance the efficiency of controller testing, validation, and analysis. As intelligent driving progresses from Level 2 to Level 3 automation, domain controllers are gradually replacing drivers' perception and decision-making functions. In ensuring safety, besides conducting vehicle driving tests on public roads, simulation testing undoubtedly adds an additional layer of safety-protection.

VCARSYSTEM's Solution

The AD HIL closed-loop solution integrates advanced scene simulation technology with real-time data processing capabilities. It involves real-time injection of virtual sensor data into the intelligent driving domain controller (DC), and receives and processes data feedback from the DC in real-time. This process ensures a closed-loop data system, significantly enriching controller testing scenarios. It enhances testing efficiency and accuracy, providing robust support for the safety validation of ADAS/AD technologies.
