Summary
This report was created by MarkLines based on patent information from the "AI Ninja" technical information distribution service provided by Toyota Technical Development Corporation (TTDC), and covers current technology topics surrounding the automotive industry. TTDC operates an intellectual property (IP) business and a measurement and control business. The intellectual property business collects and analyzes information on global automobile development, provides consulting on research projects, and handles foreign patent applications and technical translations.
With the spread of autonomous vehicles, the development of IVI (In-Vehicle Infotainment) is progressing. IVI is expected to improve the safety, convenience, and comfort of drivers and passengers. This report investigates technology trends in the entertainment field of IVI.
The “Infotainment” in IVI is a combination of the words "information" and "entertainment," and refers to digital services provided inside the car. This report examines 10 companies: Panasonic Holdings Corporation (Panasonic), Denso Corporation (Denso), Toyota Motor Corporation (Toyota), Mitsubishi Electric Corporation (Mitsubishi Electric), Alps Alpine Co., Ltd. (Alpine), Honda Motor Co., Ltd. (Honda), Sony Corporation (Sony, Faurecia Clarion Electronics Co., Ltd. (Clarion), Denso Ten Ltd. (Denso Ten), and Pioneer Corporation (Pioneer).
As for patent applications filed since 2020, the number of patent applications filed in 2021 and 2022 was high, but it has been on a downward trend since 2023. By company, including those filed before 2020, Denso has filed the most patent applications, followed by Toyota, Alpine, and Mitsubishi Electric. Looking at the top 10 companies, Toyota and Honda have filed the most applications throughout the entire period, with Toyota in particular consistently maintaining a high level and filing the most applications in 2021. Overall, the number of patents filed peaked between 2021 and 2022, after which there has been a downward trend. Additionally, no applications were filed by Panasonic or Clarion. In terms of in-vehicle infotainment technology fields, companies are focusing on "communications and connected technology," "entertainment and VR technology," and "navigation and route guidance technology." Overall, it appears that the industry as a whole actively filed patent applications from 2021 to 2022, and although this has decreased since then, technological development in specific fields continues.
