This report was prepared by MarkLines based on patent information from the "Technical Information Distribution Service - swimy" provided by Toyota Technical Development Corporation (TTDC), and reports on recent technology topics surrounding the auto industry. The two business areas of TTDC are intellectual property (IP) and measurement control solutions. The IP side of TTDC is involved in the collection and analysis of information on automotive technology developments globally, and provides services such as consulting for research planning, applying for patents in foreign languages, and technical translation.

  In recent years, the use of generative AI has been increasing in the automotive industry, and at this year's Auto Shanghai 2025 motor show, several companies presented products that use generative AI in cars. This report will show the trends in technology classifications and development subjects for the use of generative AI in automobiles in patent information from 2020 onwards.

  The number of patent applications in this field is increasing sharply, from 30 in 2022 to 401 in 2023. Development subjects include themes such as "Innovation in in-vehicle voice dialogue using LLM (Large Language Model)," "AI-equipped driver assistance and integrated vehicle control systems," "High-performance node management and high-precision time synchronization for in-vehicle Ethernet," and "AI-driven driver assistance and multi-function in-vehicle systems." In terms of technology classification, there are many patent applications in the fields of "AI-based action planning and control in vehicle operation," "In-vehicle AI companion and driver monitoring," and "Digital twin and simulation with generative AI."
