Audi has been testing the local server solution Edge Cloud 4 Production (EC4P), a new method of IT-based factory automation, at Bllinger Hfe since July 2022. Starting in July 2023, this paradigm shift in Audis shop floor IT will be used for the first time in series production. At Bllinger Hfe, a local server cluster will control the worker support systems for two production cycles of the Audi e-tron GT quattro, RS e-tron GT, and Audi R8 models. In the future, the software-controlled, flexible, and scalable server solution will replace the decentralized control system that relies on high-maintenance industrial PCs. EC4P allows Audi to redeploy the computing power the production line requires to local data processing centers. In addition to this first application in series production, Audi is simultaneously adapting EC4P for other use cases in the Audi Production Lab (P-Lab).

EC4P uses local servers that act as data processing centers. They can process extensive production-related data with low latency and distribute it to the worker support systems, which indicate to employees which vehicle part to install. This approach eliminates the need for expensive, high-maintenance industrial PCs.

Our motto is software, not hardware, said Sven Mller and Philip Saalmann, Head and Co-head of the 20-member EC4P project team. EC4P enables the quick integration of software and new tools, whether for worker support, bolt control, vehicle diagnostics, predictive maintenance, or energy savings, explained Mller. Moreover, by eliminating industrial PCs on the line, EC4P mitigates the risk of malware attacks. Jrg Spindler, Head of Production Planning and Production Technology at Audi, emphasized the opportunities of EC4P: We want to bring local cloud solutions to production at our plants to take advantage of advances in digital control systems.

The server solution makes it possible to level out spikes in demand across all virtualized clients, speeding application deployment and ensuring more efficient use of resources. Production will be economized, particularly where software rollouts, operating system changes, and IT-related expenses are concerned. The flexible cloud technology also scales to adapt to future tasks. What were doing here is a revolution, announced Gerd Walker, Member of the Board of Management of AUDI AG Production and Logistics, at the launch of the first test phase. This first application in series production at Bllinger Hfe is a crucial step toward IT-based production.

In July 2023, Audi will integrate EC4P into series production following a test run in operation and preliminary testing. The small-scale series produced at Bllinger Hfe is ideal for testing ECP4s capacity as a control system and its use in large-scale production, said Saalmann. Audi is the first car manufacturer in cycle-dependent production to use a centralized server solution that redeploys computing power. Production cycles 18 and 19 at Bllinger Hfe, during which interior panels are installed and work is done on the underbody, use thin clients capable of power-over-Ethernet. These terminal devices get electrical power via network cables and obtain data through local servers.

By the end of the year, Audi will switch the worker support systems for all 36 cycles to the server-based solution. The architecture of the server clusters is designed to enable rapid scaling of EC4P in large-scale production. With EC4P, we are merging the fields of automation technology and IT to advance our practical use of the Internet of Things, said project manager Mller. This development will also create new employee roles at the interface of production and IT. For example, employees will use new applications to control automation technology. To this end, we are setting up a control team with overarching expertise to supervise and monitor the EC4P system around the clock. The team will work closely with the line employees.

Audi is studying how digital innovations affect the working environment as part of its Automotive Initiative 2025 (AI25) in collaboration with partners, including the Fraunhofer Institute for Industrial Engineering. The AI25 takes a holistic approach, giving equal consideration to technology, people, and Audis mission of advancing the digitalization of its production activities.

We work as a team to free up resources for new areas like battery and module production, said Spindler. New technologies and collaboration models will require our teams to acquire new skills. For that reason, our employees qualifications play an important role. With its longer cycle times, we view the Bllinger Hfe plant as a learning environment to roll out IT-based factory automation at larger sites such as Ingolstadt and Neckarsulm later.

One of the first use cases is controlling electrical commissioning activities at Audis German locations. After EC4P is proven in assembly, a further concrete step will be for the server solution to take over and monitor the programmable logic controller (PLC), which was previously hardware-based, in the automation cells in body construction. The project team is developing and testing the software alongside three manufacturers at the EC4P project house in Ingolstadt.
