The future of mobility will be shaped by automated and autonomous vehicles. With a steadily increasing number of driver assistance systems, a key question remains: How can we guarantee the continuous functionality of these ADAS/AD systems, thereby ensuring road safety throughout a vehicle’s lifetime? Ryme Worldwide and Rohde & Schwarz are answering this by introducing a new solution. It seamlessly integrates radar target simulation into existing workshop environments, enabling comprehensive ADAS and AD testing during periodic technical inspections (PTI).
Maintaining the functionality of advanced driver assistance systems (ADAS) and autonomous driving (AD) features is crucial for long-term vehicle safety and performance. Hence, autonomous vehicle manufacturers must secure approval from transport authorities. Furthermore, preserving ADAS/AD functionality over time demands extra precautions.
Radar target simulators are usually used in the development and production phases of a radar sensor, under controlled laboratory conditions. These simulators are often highly complex, expensive, and designed to operate in a radio frequency controlled laboratory environment. However, Rohde & Schwarz’s innovative approach allows for the first time, cost-effective, high-quality testing of radar sensors in a workshop setting.
A further benefit for PTI testing is that the RadEst can be integrated with the new generation analogue and digital headlight testers from Ryme Worldwide, the R-HLT20/R-HLT30. The column of the headlight tester carries both test systems and can be easily moved with the chassis on rollers. The system can be provided as analogue or digital headlight tester and the customer has the benefit to save the test results and transfer them using the integrated ASA interface. The headlight tester is fully adjustable to cover various headlight technologies, e.g. H7, Xenon, LED and Matrix. The digital headlight tester has an excellent user interface and supports the daily testing routines. One more benefit is to save space as the same occupied testing area can be used for the combined R&S and Ryme solution.
The R&S RadEsT radar target simulator, developed by Rohde & Schwarz, boasts exceptional resilience to external factors, ensuring reliable performance in workshop environments. Its capability to provide precise and repeatable measurements makes it a invaluable tool for accurate real-world assessments. Moreover, with its internal analysis capabilities, R&S RadEsT can directly measure essential radar sensor quality indicators such as EIRP (Equivalent Isotropic Radiated Power) and occupied bandwidth. Its compact and lightweight design allows for easy, flexible integration, all while maintaining a cost-effective price point.
Working in collaboration with Ryme Worldwide and utilizing the R&S RadEsT radar target simulator from Rohde & Schwarz, a foundation has been established to incorporate radar sensor checks in future PTI. This will help ensure the proper functioning of vehicles’ autonomous driving capabilities throughout their lifetime.
