AI-assisted Diagnosis





Vehicle diagnosis currently requires extensive prior knowledge and a lot of time.





Development of a process
for automated detection of potentially defective components in a vehicle with the help of AI.




Added Value

The complexity due to different vehicle types can be better managed and the performance of vehicle diagnostics thus becomes more efficient.

The company Hella Gutmann develops intelligent solutions for the repair and maintenance of cars and motorbikes of all makes and models, especially in cooperation with independent garages.

In the AI Marketplace, the company’s primary focus is AI-assisted vehicle diagnostics. Traditionally, potentially defective components in the vehicle are identified using fault codes and sensor values. Currently, a mechanic needs a lot of time in the workshop as well as extensive automotive knowledge in order to make a well-founded diagnosis on the basis of read-out error codes or measured sensor values (e.g. injection quantity). In addition, a large number of different vehicle brands are repaired in independent workshops, which increases the complexity.

Detecting defective components automatically with AI

The aim of this project is to develop and test methods for the automated detection of potentially defective components in the vehicle using artificial intelligence. In particular, suitable methods for data pre-processing and the training of machine learning models with the help of vehicle data
(fault codes, sensor readings and KM states) are to be developed and validated.

Furthermore, it is examined whether common models from the field of machine learning are suitable for application to vehicle diagnostics. Finally, these models are integrated into a prediction model for defective components. This prediction model will be optimised step by step through feedback from automotive experts and transferred into a demonstrator for AI-assisted vehicle diagnostics.

A demonstrator for the AI Marketplace

With this project, Hella Gutmann is developing a demonstrator in the form of a service that uses machine learning models to provide a list of potentially defective components for a specific automotive diagnostic case. In the future, the integration of this service into a product is planned. With the help of this AI solution, it will be possible in future for mechanics to better manage the complexity that arises from different vehicle types and thus also to carry out vehicle diagnostics significantly faster.

AI-assisted Service Engineering

How can service technicians be optimally supported? A pilot project by Diebold Nixdorf Systems together with Fraunhofer IOSB-INA is dedicated to this question. The aim is to develop an AI application that reads and analyzes service and sensor data from ATMs in the field. Based on this, differentiated repair instructions for service technicians are to be generated. An existing service platform will serve as a database.

AI-assisted Producibility Analysis

A set-up process in an automated manufacturing process that is optimized with the help of AI and replaces the previously manual “teaching” – this is the core of a project by düspohl Maschinenbau GmbH and the Fraunhofer IEM. In addition, the probable producibility of new product specifications is to be assessed automatically.

Intelligent Product Monitoring

The goal of Ubermetrics’ project is an AI application that extracts relevant information from unstructured or semi-structured texts (e.g. online ratings, complaint emails, service reports, complaint reports), analyzes it and makes it systematically available to a developer. The application can be used, for example, in the context of targeted optimization of system components.

Integration of AI in Computer Aided Design (CAx)

Artificial Intelligence has the potential to fundamentally change the way we work and operate. CLAAS GmbH & Co. KGaA, an internationally active manufacturer of agricultural machinery, has recognised this potential and is testing a special use case for the integration of AI in Computer Aided Design (CAx) in the AI marketplace together with the Fraunhofer Institutes IEM and IPK.

AI-assisted Production Planning

The project of Westaflex in cooperation with the Fraunhofer IEM focuses on an AI application that helps to optimize the sequence planning of production orders. For this purpose, real-time data from production control as well as from machines are to be evaluated in order to extract hints for optimal machine allocations.
