The use of artificial intelligence (AI) is a central element of the digital transformation process at the BMW Group. The BMW Group already uses AI throughout the value chain to generate added value for customers, products, employees and processes.
Michael Würtenberger, Head of ‘Project AI: “Artificial intelligence is the key technology in the process of digital transformation. But for us the focus remains on people. AI supports our employees and improves the customer experience. We are proceeding purposefully and with caution in the expansion of AI applications within the company. The seven principles for AI at the BMW Group provide the basis for our approach.”
The BMW Group continues to follow global developments in terms of both technological innovations and regulatory and ethical issues. Together with other companies and organisations, the BMW Group is involved in shaping and developing a set of rules for working with AI, and the company has taken an active role in the European Commission’s ongoing consultation process.
Building on the fundamental requirements formulated by the EU for trustworthy AI, the BMW Group has worked out seven basic principles covering the use of AI within the company. These will be continuously refined and adapted as required according to the multi-layered application of AI across all areas of the company. In this way, the BMW Group will pave the way for extending the use of AI and increase awareness among its employees of the need for sensitivity when working with AI technologies.
Seven principles covering the development and application of artificial intelligence at the BMW Group:
- Human agency and oversight.
The BMW Group implements appropriate human monitoring of decisions made by AI applications and considers possible ways that humans can overrule algorithmic decisions.
- Technical robustness and safety.
The BMW Group aims to develop robust AI applications and observes the applicable safety standards designed to decrease the risk of unintended consequences and errors.
- Privacy and data governance.
The BMW Group extends its state-of-the-art data privacy and data security measures to cover storage and processing in AI applications.
The BMW Group aims for explainability of AI applications and open communication where respective technologies are used.
- Diversity, non-discrimination and fairness.
The BMW Group respects human dignity and therefore sets out to build fair AI applications. This includes preventing non-compliance by AI applications.
- Environmental and societal well-being.
The BMW Group is committed to developing and using AI applications that promote the well-being of customers, employees and partners. This aligns with the BMW Group’s goals in the areas of human rights and sustainability, which includes climate change and environmental protection.
The BMW Group’s AI applications should be implemented so they work responsibly. The BMW Group will identify, assess, report and mitigate risks, in accordance with good corporate governance.
Overall centre of competence for the company: “Project AI”.
‘Project AI’ was launched in 2018 to ensure that AI technologies are used ethically and efficiently. As the BMW Group’s centre of competence for data analytics and machine learning, it ensures rapid knowledge and technology sharing across the company. Project AI therefore plays a key role in the ongoing process of digital transformation at the BMW Group and supports the efficient development and scaling of smart data and AI technologies. One of the developments to come out of Project AI is a portfolio tool which creates transparency in the company-wide application of technologies making data-driven decisions. This D³ (Data Driven Decisions) portfolio currently spans 400 use cases, of which more than 50 are available for regular operation.
Since 2018, the BMW Group has been using various AI applications in series production. One focus is automated image recognition: In these processes, AI evaluates component images in ongoing production and compares them in milliseconds to hundreds of other images of the same sequence. This way, the AI application determines deviations from the standard in real time and checks, for instance, whether all required parts have been mounted and whether they are mounted in the right place. At the BMW Group, flexible, cost-effective, AI-based
applications are gradually replacing permanently installed camera portals. Implementation is comparatively simple. A mobile standard camera is all that is needed to take the relevant pictures in the production hall. The AI solution can be set up quickly too. Employees take pictures of the component from different angles and mark potential deviations on the images. This way, they create an image database in order to build a neural network, which can later evaluate the images without human intervention.
Name Plate Checks.
In the final inspection area at the BMW Group’s Dingolfing plant, an AI application compares the vehicle order data with a live image of the newly produced car’s model badge. Model designation badges and other identification plates (such as “xDrive” for all-wheel drive vehicles and all generally approved combinations) are stored in the image database. If the live image and order data don’t correspond – if a designation is missing, for example – the final inspection team receives a notification. Read the full application story.
Dust Particle Analysis in the Paint Shop.
AI can control the operation of highly sensitive automotive production equipment even more precisely, as a pilot project in the paint shop at the BMW Group’s Munich plant has shown. If levels of dust increase due to the time of year or a sustained dry period, the algorithm picks up on the trend at an early stage and brings forward the timing of a filter change, for example. Working in conjunction with other analysis tools, additional patterns can be recognised. Another result of the analysis might be that fine adjustments need to be made to the machine using ostrich feathers to remove dust particles from the car body. The BMW Group’s AI experts see great potential in dust particle analysis. Supplied with information from numerous sensors and data from surface inspection, the algorithm monitors more than 160 features of the body and can predict the quality of a paint application with great accuracy.

AI Control Application in the Press Shop Reliably Prevents Pseudo-Defects.
At the press shop, flat sheet metal parts are turned into high-precision components for the car body. Dust particles or oil residues that remain on the components after forming can easily be confused with very fine cracks, which occur in rare cases during the process. Previous camera-based quality control systems at the BMW Group’s plant in Dingolfing occasionally also identified these pseudo-defects (deviations from the target values, but with no actual fault). With the new AI application, these pseudo-defects no longer occur because the neural network can access around 100 real images per feature – i.e. around 100 images of the perfect component, 100 images with dust particles, another 100 images with oil droplets on the component, etc. This is particularly relevant in the case of the visually close calls that have previously led to pseudo-defects.
