HiL - Hardware-in-the-Loop


b-plus offers you high-precision hardware in combination with modular software for your individual AD HiL and ADAS HiL application:

  • Radar HiL
  • Lidar HiL
  • Camera HiL
  • Replay / Report HiL
  • Simulation HiL

With our smaller HiL testing tools we enable early error detection as well as debugging of your sensor/controller algorithms directly at your development table.

In addition, we offer highest scalability with expansion possibilities up to a fully equipped HiL rack system for high bandwidths in 24/7 operation.

Benefit from the know-how of a data specialist and use it for your data processing in the Hardware-in-the-Loop testing area.

In the technical paper "Validating ADAS/AD Functions Safely", published in the magazine Hanser automotive 05/22 in German language, the characteristics of open and closed loop HiL systems are explained. Furthermore, the importance of synchronous playback of raw sensor data, vehicle BUS and network information in the validation of ADAS/AD functions is illustrated.

The article "High-Performance Hardware-in-the-Loop Systems for Sensor Validation," (in German language) which appeared in the 2022 Annual Report of the Cluster Automotive, discusses the flexibility of Hardware-in-the-Loop systems when used in various testing scenarios.

Benefit from the hardware and software solution perfectly matched to each other for your individual HiL application - all from a central partner!

Highest scalability

We offer open-loop and closed-loop processes that support all phases of development. The complex system can be split down to modular, self-contained and simple single modules. The combination and integration of the modules will be adapted according to the customer's workflow:

  • b-HiL for realtime injection directly at the test table
  • CONiX HiL Solution as HiL integrator
  • CONiX HiL Solution XXL as HiL rack system
