London, January 09, 2025, (Oilandgaspress) –––Thanks to artificial intelligence (AI), large language models (LLMs) can understand natural language and perform tasks such as text creation, answering questions or even translation. Porsche Engineering also uses LLMs in vehicle development, thereby increasing efficiency in the development process.
Porsche Engineering uses LLMs to further increase efficiency in the development process. The company uses commercially available LLM tools such as ChatGPT from OpenAI or LLaMa from Meta. “These models are pre-trained by very large amounts of data from the internet and handle tasks such as writing texts on standard topics very well. For use in development, however, we need an LLM that also takes into account our engineering expertise,” says Schaper.
The technical knowledge of Porsche Engineering is taught to the AI using its own data sets from completed development projects. One area of application for LLMs is the revision of customer specifications. Depending on the project, the client, and the development team, their content is written in very different forms. If an existing system is to be technically updated as part of a further development, Porsche Engineering often receives the requirements from existing customer specifications and the scope of the changes from its customers.
Before the actual development task starts, the developers must completely work through the customer specifications and translate the information contained therein into concrete technical specifications in order to avoid development errors due to ambiguous specifications. Porsche Engineering has recently begun using predefined block templates in the revision of specifications: A basic principle of requirements engineering for the standardized and qualitative creation of requirements. With the aid of this methodology, information is presented in a way that is clear, consistent, verifiable, accurate, and understandable. “Today, our engineers have to do the revision of the specifications as a manual activity. This ties up resources in development and is a monotonous activity for the employees,” says Volker Reber, Senior Manager High-Voltage System Development at Porsche Engineering.
