Tech partners collaborate on HiL ADAS testing

| Information and Communication Technology

Konrad and SET have combined their expertise to produce Hardware-in-the-Loop simulated testing systems for ADAS based on NI platform.

Due to continuously rising demands on mobility and autonomous driving, integrated and automated testing systems are needed for Advanced Driver Assistance Systems (ADAS). The combination of ADAS sensor fusion with a Hardware in the Loop (HiL) testing system is necessary to enable a new level of innovative, automated testing systems in the automotive industry.

To meet this demand, Radolfzell based Konrad Technologies and SET GmbH are joining their knowledge and skills to develop custom testing systems in the area of driver assistance systems. Together, the extraordinary expertise on ADAS sensor fusion of Konrad Technologies and on HiL by SET GmbH form a complete, flexible set of tools from design to development, implementation and validation to production. This combination of skills allows optimal systems to be offered to shared customers.

The agreement provides for a collaboration between the two long-time, award-winning National Instruments Alliance partners, both on technical as well as strategic activities. Both companies are successful system providers for innovative testing systems in the automotive industry – from the initial idea all the way to end-of-line (EOL) tests. The focus is increasingly on National Instruments products, which are extended with their own products and systems to enable high-performing and high-precision combinations. Based on the in-depth experience of both companies, the focus of design is on considering the Total Cost of Test (TCoT), which allows a significant reduction thereof through suitable standardisation efforts.

To test modern ADAS sensors efficiently, Konrad Technologies has developed target simulators for camera, radar, and LIDAR sensors, which have been successfully used in the field by clients in the past years. The software for radar target simulation offers the opportunity to simulate typical driving scenarios in a laboratory environment. This allows a controllable and reproducible testing framework, which is a prerequisite for an objective and independent performance analysis of the sensor system. Based on the National Instruments VST, a Vector Signal Transceiver, Konrad developed an editor that allows the user to create complex scenarios that can be automatically reproduced.

With the aid of Hardware in the Loop (HiL), individual parts of an integrated system can be simulated and tested in a virtual environment in real time. SET GmbH has specialised in HiL for a number of years and was named the Hardware in the Loop Speciality Partner by National Instruments. HiL simulation allows for an efficient assessment of systems while reducing testing time and costs and increasing reliability by replacing complex, real tests. With regard to ADAS sensor fusion, the complexity lies in integrating target simulators, classic analogue and digital signals possibly including signal conditioning, control and evaluation of vehicle CAN and FlexRay buses, as well as the consideration of a car model. The HiL environment guarantees the parallel execution of all individual components in real time.

Frank Heidemann, Managing Director of SET GmbH commented, “The fusion of a multitude of sensor information, more intelligent control devices and the customers’ desire for better assistance systems and even autonomous driving presents our customers with interesting but also growing challenges. With Konrad Technologies, we have found a partner that, with their in-depth know-how of ADAS sensor systems, represents the perfect complement to the HiL skills of SET GmbH. Together, we can offer our customers HiL systems from ADAS sensor systems all the way to closed sensor fusion HiL test beds and, therefore, provide users the optimal tools for solving the challenges of the future. In addition to the technical connection, our company values are an excellent match, making it fun to work on solving these problems together with Konrad as a reliable and flexible partner.”

Michael Konrad, Managing Director of Konrad Technologies added, “SET, with its long-standing expertise in Hardware in the Loop (HiL), is the perfect partner for continuing development in sensor fusion simulation systems. Future ADAS systems will be increasingly complex and thus require complex systems for efficient and safe validation. Time to market is a crucial factor, providing our customers with the necessary time and engineering. I’m especially excited about collaborating with SET because Konrad Technologies and SET have similar philosophies and have both been successful for many years.”
