MAHLE and Rohde & Schwarz Develop Application for Sensor Testing of Modern Driver Assistance Systems

"With this innovation, we are taking driver assistance systems to the next level. For the first time, their functionality after a repair becomes measurable, traceable, and standardizable. This is not only a technological advancement — it is a decisive step toward greater safety, transparency, and trust across the entire mobility ecosystem," said Felix-Matthias Walter, Director Service Solutions at MAHLE Lifecycle and Mobility.

"This is a milestone for vehicle safety. Our radar measurement technology is already used worldwide in automotive development and production. Together with MAHLE, we are now bringing this level of measurement accuracy directly into the workshop," explained Matthias Beer, Director Imaging Sensor Products at Rohde & Schwarz.

The TechPRO(R) Digital ADAS 2.0 Extra calibration system from MAHLE uses integrated ultrasonic sensors to ensure precise vehicle positioning directly from the interior. Automatic vehicle identification, laser-based distance measurement, and motorized adjustment of the target systems enable an efficient calibration process. An optimized display lift system additionally guarantees precise alignment even for particularly tall vehicles.

The R&S(R) RadEsT radar tester from Rohde & Schwarz adds capabilities beyond those of pure calibration devices — such as frequency and polarization detection, power measurement, and target and angle simulation for radar sensors. With this feature, technicians can verify and identify the correct alignment and function of radar sensors following repairs or damage using the MAHLE TechPRO(R) 2 diagnostic tool.

The joint development covers several key application areas. Following repairs, it provides workshops with standardized and documented confirmation that the driver assistance system continues to operate within specification. It is also suited for quality and performance testing, since both correct and faulty system states can be deliberately simulated. Finally, the system generates reproducible and audit-proof measurement data that can serve as the basis for periodic technical inspection procedures, regulatory requirements, or insurance assessments in the future.
