TESTING Next generation A powerful toolset provides the technical evaluation framework needed to meet the rigorous testing demands of autonomous vehicles A By Bojan Čontala, Dewesoft dvances in ADAS and AVs have introduced significant complexity into vehicle safety and control systems. These systems rely on a range of sensors and data streams to make split-second decisions in dynamic environments, requiring precise and comprehensive testing frameworks. Dewesoft’s suite of tools, particularly the Obsidian data acquisition system, provides the necessary infrastructure for thorough, real-time, multichannel data acquisition and testing of these systems. The importance of ADAS testing ADAS technology integrates a variety of sensing and decision-making systems. The ability of these systems to accurately detect and respond to real-world scenarios – such as avoiding collisions, maintaining lane integrity and recognizing pedestrians – is crucial to vehicle safety. Testing these systems requires high-precision measurements, synchronization and data from multiple channels. Accurate ADAS testing is predicated on measuring the relative distances between the vehicle under test (VUT) and surrounding objects in real time. This requires robust sensor integration, seamless data handling and advanced processing to confirm that ADAS features like emergency braking and lane departure warnings are functioning as expected. Dewesoft’s Navion i2 IMU, paired with GNSS and MEMS technology, serves as the cornerstone of relative position measurement. This sensor fusion system reduces setup time while improving accuracy, crucial for evaluating ADAS responses in different traffic scenarios. Dewesoft’s Polygon module offers an advanced method for calculating real-time distances between objects, creating a framework where ADAS sensors can be validated under dynamic conditions. Meanwhile, Dewesoft’s Obsidian data acquisition system enhances the ADAS testing landscape by providing a high-channel, high-bandwidth solution specifically engineered for handling complex, multisensor environments. Its ability to manage up to 1,000 data channels ensures that large-scale ADAS and AV testing Robot connection with DAQ and Navion scenarios can be captured and analyzed without loss of information. (See Key technical features of Obsidian , opposite, for further features.) Data synchronization and real-time feedback A central aspect of ADAS and AV testing is maintaining consistent and synchronized data flows. The integration of multichannel data from various sensors, such as lidar, radar and cameras, is paramount for ensuring that decisions made by the vehicle’s ECU occur at the right time and in response to the correct stimuli. Dewesoft’s systems achieve nanosecond-level synchronization using GNSS and other time-sync protocols, ensuring that all systems work harmoniously. 56 ADAS & Autonomous Vehicle International January 2025
