ADAS HIL System

The efficient and easy coupling of the professional and proven Vector hardware and software toolchain leads to an ideal combination for the test of ADAS/AD functions: Comprehensive options for closed-loop system tests can be used with consistent workflows from early development stages through to real hardware with the Vector VT System.
 

Advantages

  • Automated test driving of thousands of kilometers – in the HIL lab
  • Off-the-shelf components working smoothly together
  • Fast and easy configuration of the HIL system
  • Modular and flexible test set-up
  • Manual testing in the same way as a real driver in the vehicle
  • Automated testing: comfortable configuration and full integration of test automation
  • Simulation and test of ECU diagnostics
  • Detection and correction of error situations early in the development process

Applications

Testing of ADAS Functions

  • Environment perception
    Lane detection, traffic sign recognition, object detection, simultaneous localization and mapping (SLAM) etc.
  • Comfort functions
    Adaptive cruise control (ACC), traffic jam assistant, parking pilot etc.
  • Safety systems
    Pre-crash, front collision warning (FCW), automated emergency braking (AEB), lane keeping assistant, blind spot monitoring etc.
  • Automated driving
