USE CASES FROM DIFFERENT AREAS OF THE COMPANY.
The following examples show that Project AI pushes the BMW Group forward with AI focused, company-wide networking and knowledge transfer. The fundamentally identical technology forms of AI can generate added value for customers, employees and business processes. For example, the customer benefits from natural language processing (NLP) with the Intelligent Personal Assistant directly in the vehicle and employees are supported with translation tools and context-processing assistants in administrative processes.
Intelligent data analysis and machine learning are used to optimise energy management both in buildings and in vehicles. And image processing AI relieves both the customer with driver assistance systems from monotonous driving tasks and employees in production from monotonous processing steps.
E XAMPLES FROM RESEARCH & DEVELOPMENT.
AI-based energy management in vehicles.
A vehicle contains a large number of electric consumers, such as seat heating, the entertainment system, the air conditioning, etc. In many cases, the driver is not aware that using these consumers also has an effect on CO2 emissions and/or the range of the vehicle.
AI experts at the BMW Group are conducting R&D work on AI-based software for in-vehicle energy management. Taking user behaviour and route information as a basis, the system learns how to adjust energy consumption in the car as effectively as possible to the driver’s requirements and the need for energy efficiency. In this way, CO2 emissions can be reduced, energy saved and operating range increased.
Acoustic analytics: sensory enhancement in the sensor model for automated driving functions.
The BMW Group is taking an all-encompassing approach to monitoring the vehicle environment. One of the areas the company is exploring to this end is how acoustic signal processing can be added to the AI sensor fusion. Incorporating auditory perception can have benefits for urban scenarios, in particular, going forward.
AI in requirements management.
At the BMW Group there are over 33,000 requirement specification documents containing more than 30 million individual requirements for vehicles, components and characteristics. That’s an enormous amount of data. AI technologies can help employees to process large quantities of data more quickly and carefully.
Here, an application has been developed which uses natural language processing methods to improve the quality and analysis of individual requirements in specification documents. The web-based tool allows thousands of requirements to be automatically translated and checked – in real time – for linguistic quality, similarity and consistency.
EXAMPLES FROM SUPPLY CHAIN MANAGEMENT AND LOGISTICS.
Integrating AI with facility and robot control systems.
The first smart AI control application at the BMW Group celebrated its premiere at the BMW Group’s Steyr plant. This application speeds up logistics processes by preventing the unnecessary transport of empty containers on conveyor belts. To this end, the containers pass through a camera station.
Using stored image data marked by employees, the AI application recognises if a container needs to be lashed onto a pallet or whether – in the case of large, stable boxes – no additional securing is required. If no lashing is required, the AI application directs a container by the shortest route to the removal station for the forklift truck.
Besides the application in Steyr, AI can be found in numerous other logistics innovations at the BMW Group. It also supports virtual layout planning, which creates high-resolution 3D scans of buildings and factories. AI ultimately contributes to the recognition of individual objects in the 3D scans, such as containers, building structures and machines.
In this way, robotics applications out-perform the technology used previously in their coordination skills and ability to recognise people and objects. Navigation improvements enable obstacles such as forklift trucks, tugger trains and employees to be detected more quickly and clearly, and alternative routes to be calculated within milliseconds. The AI-based technology helps the robotics applications to learn and apply different reactions to people and objects.
EXAMPLES FROM PRODUCTION.
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. You can find more information here.
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. You can find more information here.
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. You can find more information here.
BMW won the Connected Car Pioneer Award 2020 in recognition of its versatile use of AI in production.
EXAMPLES FROM AFTERSALES & CUSTOMER SERVICE.
AI at dealer service desks.
If a BMW customer visits a dealer reporting a problem with their car, the problem needs to be identified quickly and the right solution found reliably.
To help them do this, the service employee has the use of a knowledge database, which has been expanded using a powerful software stack to include both an intelligent and scalable search facility and AI (for processing problem cases and knowledge data). AI incorporates context information into the search process, enabling it to flag up identical and similar cases. Added to which, an automatic translation function breaks down the language barrier in the fault analysis process.
AI-based customer interaction in WeChat.
Chatbots help to significantly increase the quality and availability of customer service. In China, BMW Financial Services offers its customers an AI-based chatbot via the widely used WeChat app. The chatbot allows customers to ask questions regarding their personal finance agreement or make changes to their agreement. These bots are first trained to deal with the topics for which most questions are received by the call centre.
If the chatbot cannot answer a question, the enquiry is passed to a human member of staff. This means that customers’ most frequently asked questions can be answered quickly and with a consistently high level of quality around the clock.
EXAMPLE IN BUILDINGS MANAGEMENT.
Increasing energy efficiency in BMW Group buildings.
Since 2006 the BMW Group has been able to consistently increase energy efficiency at its locations around the world. It has now reached such a high level that identifying further potential for improvement using conventional means is getting more and more difficult. This is where the use of smart data and AI comes into play.
The BMW Group systematically processes all the energy-relevant data at its locations so previously undiscovered energy consumption patterns can be established using AI. Weather-related data can also be incorporated into this process, enabling buildings to be heated and cooled more intelligently and efficiently. In a pilot project in Munich, this approach has allowed approximately 1,200 MWh of thermal energy to be saved annually in the IT centre.
This equates to the energy consumption of approximately 60 family homes. This experience and a rigorous process of data collection and analysis have also led to positive energy efficiency results at office buildings such as the BMW four-cylinder building, FIZ Projekthaus, Campus Freimann and the dynamics centre at Dingolfing.
EXAMPLE FOR ADMINISTRATION & SUPPORT FUNCTIONS.
Customized Machine Translation (CMT) – machine translation that learns the language of BMW.
The BMW Group is a multinational company with a presence in over 100 countries. Its customers, dealers and employees speak hundreds of languages and there is an enormous daily influx of multilingual texts from external sources. Human translation of all multilingual data does not make sense due to the volume and costs involved.
Freely available translation solutions are not permitted for reasons of information protection and often fail to provide the correct translation of technical terms and formulations – the correct “BMW language”. With this in mind, BMW Group IT has developed its own translation solution specialising in BMW texts. BMW Group employees are now feeding over 2,000 sentences into the system every day.
EXAMPLES FOR CUSTOMER AND VEHICLE FUNCTIONS.
AI is the key to automated driving – and is already present in current driver assistance systems such as Driving Assistant Professional. Automation-based functions help customers to drive safely, park and stay connected. On motorways, they can take over longitudinal and lateral guidance of the vehicle for extended periods. The customer remains responsible for the car, but their task is now only to monitor what is happening.
BMW Intelligent Personal Assistant.
The BMW Group has revolutionised driving pleasure with the BMW Intelligent Personal Assistant. Introduced in 2019, this intelligent digital on-board companion responds to the prompt “Hey BMW”. The BMW Intelligent Personal Assistant increasingly allows the car to be operated, functions to be accessed and information obtained by voice command alone. This technology enables direct communication and natural interaction with the vehicle – helped by AI.
