OCEAN  LGM Ingénierie's new protocol stack for embedded networks

Safe, autonomous and connected mobility


LGM Ingénierie has been developing and producing protocols stacks for some fifteen years. The current version of the product has enabled the company to finance a campaign to modernize this stack. The new OCEAN (Ocean Connects Embedded Application to Network) protocols stack for embedded networks will thus comply with the ISO 26262 standard, which sets out the rules in terms of functional safety for land vehicles.


What is LGM Ingénierie's objective in modernising the OCEAN protocols stack?


LGM Ingénierie develops and manufactures software components dedicated to functional and diagnostic communication between embedded ECUs. The OCEAN protocols stack is an embedded software solution configurable to enable different vehicle equipment to communicate with each other through one or more communication networks. Today's vehicles are increasingly communicating, and the market will soon include hundreds of millions of traditional, electric, hybrid, autonomous and communicating vehicles devices. The OCEAN product is designed to be generic for standardised protocols (CAN, LIN, UDS, OBD, etc.) and tailor-made for manufacturer-specific protocols, and regularly participates in critical functions such as windshield wipers, pedestrian detection, battery charging, door locking, power steering, parking brake, etc. Its deployment and adaptation to specific standards for aeronautics and railways is also planned in the medium term.


“The NextMove label gives us a real credibility and helps us to mature the project presentation.” Henri DUDRAGNE, Head of Embedded Networks offer at LGM Ingéniérie.


Our solution for embedded networks is sold to automotive suppliers. The software decodes the messages and signals over the networks, enabling vehicle equipment to communicate. In addition to its technological innovations, the new product will be configurable and downloadable online from a secure web platform. Therefore customers will be able to manage and configure their project online, then download and integrate it into their ECU. There is currently no competing offer of this type in the market, even from the international market leaders. Cyber-security is an issue we've worked hard on to secure this software platform as well as the stack.


How did you finance the development of this project?


The OCEAN project is spread over 3 years (beginning of 2019 to end of 2021) and represents an investment of over one million euros, which we mainly self-financed with the deployment of the previous version of our protocols stack. We were awarded the NextMove label in January 2020, before that we have submitted our project OCEAN to participate in the Innov'up leader PIA call for projects of Paris region. Our project was got selected and we were awarded a €170,000 grant.

5 million - that's the number of vehicles that have embedded the previous version of our stack product, enabling us to finance a large part of this new OCEAN project.


Which support did NextMove give you?


NextMove's support enabled us to get to grips with the financing mechanisms, and to build and review our application. Their ability to label and provide support was a real asset when it came to supporting the project. We had a 15-minute presentation in front of NextMove experts, an interesting exercise that forced us to be synthetic and structured, and to better demonstrate the innovative aspect of the OCEAN project. Indeed, the innovation of our product consists in integrating technology, normative and manufacturer requirements, but also lies in its business model, since the stack is managed and downloadable online. This sales method is unprecedented in the sector.
