R&S, IPG team for complete Hardware-in-the-Loop radar test
Rohde & Schwarz has teamed up with IPG Automotive on an automotive radar Hardware-in-the-Loop (HIL) integration test system.
The HIL radar test system combines the CarMaker simulation software from IPG Automotive with the R&S AREG800A radar object simulator and the R&S QAT100 advanced antenna array.
This gives vehicle manufacturers the ability to simulate scenarios for ADAS and autonomous driving defined in the Euro NCAP and other standards. It can be used for validation and real-time, closed-loop characterization of radar sensors and enables compliance with ASAM open 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. 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.
A high-resolution 3D engine provides details in the simulation of the complete sensor stac, while 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.
Reference design for first 28nm short range automotive radar
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.
THe HIL chain also includes a Scenario Editor 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.
CarMaker also 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, thereby saving considerable time and effort.
The Model Manager CarMaker helps to define the configuration of virtual vehicle prototypes. This enhances the realism and accuracy of simulations, making them more useful for testing and development.
Rohde & Schwarz, Vector join forces on HiL validation of radar sensors
“With the collaboration between Rohde & Schwarz and IPG Automotive, 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,” said Andreas Höfer, Chief Technology Officer at IPG Automotive.
