CVFT 4.0 Final Updates

On the last week of January, we took a significant step forward with a fully remote diagnostics test in collaboration with ZF Group. This test focused on a BMW training vehicle with pre-existing errors, and we successfully read the vehicle data remotely, confirming errors in a report.

This session proved that remote diagnostics can function efficiently in a completely virtual format, marking another step forward in refining our diagnostic processes.

Special thanks to the amazing teams involved from ZF Group: Daniel Pfeiffer, Frank Mauder, Claus Orth, and Alexander Erhart and from our CARUSO team: Tina Rauschenbach, Christian Webel, and Andreas Pradel.

A big shoutout to our peers from ZF Group for their excellent organization and support, making this test both efficient and insightful.

On the last week of February our Connected Vehicle Field Test expanded across Europe with a session at Revolte, e-garages in Nantes, France, in collaboration with Schaeffler. Revolte, known for its expertise in electric and hybrid vehicles, partnered with us to simulate vehicle errors and assess them using both traditional and remote diagnostics.

Here’s an example of our findings:

Traditional Diagnostic Insights:

• CCU (Combined Charging Unit) – DTC: 224F81 => AC charge: Fonction non disponible (Intermittent)
• DTC: 031B93 => Charge: erreur de charge détectée par la gestion des charges (Intermittent)

Remote Diagnostic Insights:

• ECU: ccu_01 Combined Charging Unit, DTC: 2248577 (AC charging: Function not available)
• ECU: ccu_01 Combined Charging Unit, DTC: 203667 (Load: Charging error due to charge management detected)

The alignment between traditional and remote diagnostic results highlights that remote diagnostics technology is already viable and operational today! We are currently refining the pilot phase and preparing our final report.

A big thank you to our amazing partners from Schaeffler: Jan Bambas, Ronald GAMERE, Oscar Lopez Perez, Janine Girke from Schaeffler Vehicle Lifetime Solutions, and Jeremie Noirot, Florian Eon at Revolte Garages. Your collaboration and dedication have been crucial in driving this innovation forward.

Final Test at Bosch: Understanding Remote Diagnostics

On the third week of March we wrapped up our final test at Bosch in Plochingen, focusing on remote diagnostics. This marks the completion of six diverse tests in our field study, revealing fascinating insights into the differences between OEM 1 and OEM 2 remote diagnostic systems.

One key finding from this session: OEM 2 incorporates plausibility checks for their Diagnostic Trouble Code (DTC) transmission to the backend, introducing a delay in error detection. In contrast, OEM 1 provides direct readouts from the vehicle immediately. While both systems delivered results comparable to professional diagnostic testers, the OEM 2 remote readout posed some challenges in our Bosch test due to its additional verification step.

A huge thank you to our dedicated team members who made this test possible:
💜 From CARUSO: Christian Webel, Tina Rauschenbach, Andreas Pradel💙 From Bosch: Dr. Andreas Klein, Pia-Lisa Krauß, Timo S. Reif, Thiemo Brinkmann

Stay tuned for our comprehensive final report, where we will share the full scope of our findings and insights that will shape the future of connected vehicle diagnostics!

The Road Ahead

With several successful tests completed across different locations and in collaboration with multiple partners, our Connected Vehicle Field Test 4.0 is approaching its conclusion. However, there are still a few final tests and collaborations before we release our full report. Keep an eye out for updates, as we are getting closer and closer to unveiling the final results!

Thank you to all our partners, colleagues, and supporters for being part of this journey. The future of connected vehicle diagnostics is here—and we are excited to lead the way! 🚗💡
