Engineers spent months recording, extracting and interpreting signals from on-board networks (CAN, LIN, Ethernet, etc.). This was a costly delay, at a time when innovation was accelerating.<\/p>\n<p>It was against this backdrop that Dunasys Technology was approached: the manufacturer was seeking a partner capable of designing a bespoke, robust, intelligent and scalable black box.<\/p>\n<p>The challenge was clear: to transform testing into a driver of industrial performance by reducing the time between road testing and technical decision-making.<\/p>\n<h2>The origins of a solution that has grown into a product range<\/h2>\n<p>This collaboration gave rise to Dunadiag, the first data logger developed for this purpose.<\/p>\n<p>Designed to capture and correlate all vehicle data in real time, it has reduced test cycles from 12 to 4 months, whilst ensuring the reliability and completeness of critical data.<\/p>\n<p>This success laid the foundations for a comprehensive range, capable of covering all testing and validation needs:<\/p>\n<ul>\n<li>Dunadiag (2016): the first bespoke unit;<\/li>\n<li>Dunalog (2021): a modular, networked version, designed for multi-protocol testing;<\/li>\n<li>Dunalog XL (2025): high-capacity model for prototype fleets and complex tests (autonomous vehicles, ADAS, etc.);<\/li>\n<li>Dunalog E (2026): essential, compact version, suitable for lighter applications.<\/li>\n<\/ul>\n<p>Today, this range is available to order from the catalogue and is used by several European and global manufacturers: concrete proof that bespoke development can become an industry standard.<\/p>\n<h2>Project objectives<\/h2>\n<p>For our client, the initial aim was clear: to have a universal, connected data logger capable of:<\/p>\n<ul>\n<li>Simultaneously capturing network signals (CAN, CAN FD, LIN, Ethernet);<\/li>\n<li>Integrate cameras and inertial sensors to synchronise images and data;<\/li>\n<li>Automatically transmit results via 4G\/5G connectivity;<\/li>\n<li>Reduce test cycles by several months through centralised and automated analysis;<\/li>\n<li>Provide a scalable platform, adapted to future architectures and the needs of field teams;<\/li>\n<li>Have millions of high-quality data samples to power AI models<\/li>\n<li>Reduce the human cost of validation phases (less human intervention thanks to the digitisation of data transmission) &#8211; Savings on validation cycles &#8211; Cost savings as defects are spotted more quickly &#8211; Logistical savings: no unnecessary back-and-forth and remote validation<\/li>\n<\/ul>\n<h2>Solutions developed by Dunasys Technology<\/h2>\n<p>To meet these requirements, Dunasys has designed fully connected, high-performance data loggers that combine industrial-grade hardware with intelligent software.<\/p>\n<p>Every detail has been designed with extreme field conditions in mind:<\/p>\n<p>Multi-network data acquisition: CAN, CAN FD, LIN, Ethernet, UDS and J1939 protocols;<br \/>\nIntegrated inertial sensors (accelerometer, gyroscope, magnetometer, GNSS);<br \/>\nOn-board camera for video\/data correlation;<br \/>\nSecure storage from 64 GB to &gt; 1 TB (micro-SD or SSD);<br \/>\nWi-Fi \/ 4G \/ 5G and OTA connectivity for live transmission of test data.<\/p>\n<p>Thanks to this architecture, engineers were able to access driving data in real time, monitor tests remotely and reduce prototype validation time by two-thirds.<\/p>\n<p>A performance made possible by unique expertise: at Dunasys, the units are designed to be fully connected, from data collection to transmission, with no loss or latency.<\/p>\n<p><!-- notionvc: 165097ae-2fe6-4415-b512-76a1c2f8d677 --><\/p>\n<h2>Results &amp; Benefits<\/h2>\n<p>Dunalog systems have redefined the way manufacturers conduct their field tests. Thanks to their native connectivity and open architectures, they offer:<\/p>\n<p>Faster test cycles: reduced from 12 months to 4 months;<br \/>\nFull interoperability with test benches, cloud platforms and analysis tools;<br \/>\nReal-time remote monitoring, reducing travel and costs;<br \/>\nFull modularity to add cameras, sensors or extensions as required.<\/p>\n<p>Beyond the Stellantis project, Dunalog has become a standard in automotive data logging: a ready-to-use, scalable solution suited to all test environments, from prototype to production.<\/p>\n<h2>Perspectives<\/h2>\n<p><!-- notionvc: 0d2572da-7df2-4346-978d-4d114831a434 --><\/p>\n<p>The Dunalog range continues to evolve to support the transformation of the automotive sector:<\/p>\n<p>integration of on-board AI for anomaly detection and predictive analysis;<br \/>\n5G connectivity for long-term testing across all types of terrain;<br \/>\nexpansion into new sectors: autonomous vehicles, rail, marine, defence and aerospace.<\/p>\n<p>At Dunasys Technology, we see every test campaign as an opportunity for shared innovation: helping our customers go faster, further, and with complete reliability.<\/p>\n<p>Are you an automotive manufacturer, or looking for a reliable data logging solution?<\/p>\n<p>Accelerate your prototype validation with the Dunalog range, the fully connected data logging solution designed to capture, transmit and analyse your data in real time.<\/p>\n<p>Contact the Dunasys Technology teams to explore the configurations best suited to your needs.<\/p>\n<p><!-- notionvc: 7648c1b5-1d69-4639-863b-21c357109c85 --><\/p>\n<p><!-- notionvc: 36f84aa6-62d1-4fdd-b1d8-8dcba8ab553c --><\/p>\n<\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":2868,"template":"","class_list":["post-2867","projet","type-projet","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 -
