By combining CarMaker simulation software from IPG Automotive with the R&S AREG800A radar object simulator and the R&S QAT100 advanced antenna array they can now provide vehicle manufacturers with the ability to simulate ADAS/AD scenarios like those defined in the Euro NCAP in a controlled, safe, time-efficient and cost-reducing way.

This new combination provides automotive OEMs and radar sensor suppliers with a comprehensive radar sensor testing platform which is applicable for validation and real-time, closed-loop characterisation of radar sensors and enables compliance with Association for ASAM standards.

IPG Automotive’s CarMaker simulation solution is designed for development and end-to-end testing of cars and light commercial vehicles at all development stages from MIL/SIL to HIL and VIL. The open integration and test platform allows vehicle manufacturers, engineering services companies and Tier 1 suppliers to implement virtual test scenarios in the application areas of powertrain, vehicle dynamic chassis functions and ADAS/AD functions.

Thanks to a high-resolution 3D engine, the simulation of the complete sensor stack is possible in very high detail. Seamless integration into existing tool landscapes is also possible with a variety of supported standards and interfaces like the ASAM Open Standards.

The R&S AREG800A, in conjunction with the R&S QAT100, generates multiple artificial objects, each with independent range, Radar Cross Section (RCS), angle (azimuth/elevation) and radial velocity.

The Open Simulation Interface (ASAM OSI) links R&S AREG800A with the CarMaker HIL test automation, creating a comprehensive test setup, proving extremely valuable for realistic driving scenario assessment within radar HIL testing. Moreover, the solution also includes a Scenario Editor, that’s been specifically designed for non-simulation experts. This feature greatly simplifies the process of testing manoeuvre-based driving scenarios and their associated complex traffic-related configurations and makes it accessible to a wider range of professionals.

The simulation solution CarMaker features an advanced Test Manager, capable of building and running automated test sequences. It can run tests individually or simultaneously, locally or in the cloud, providing flexibility and scalability.

Additionally, it automates the calculation and evaluation of Key Performance Indicators (KPIs) and generates reports automatically, saving considerable time and effort.

The Model Manager CarMaker is intended to help define the configuration of virtual vehicle prototypes, enhancing the realism and accuracy of simulations, making them more useful for testing and development.

Andreas Höfer, Chief Technology Officer at IPG Automotive said, “With the collaboration we intend to provide the automotive industry with a comprehensive Hardware-in-the-Loop integration test solution, bringing tests from the proving ground into the lab, resulting in significant time and cost savings in the development process.”
