As advanced driver assistance system (ADAS) technology continues to advance, the driver monitoring system (DMS) field has become an essential area for R&D and business strategies of companies in the automotive industry.
This report provides a close examination and analysis of global DMS technology trends based on the latest patent information.

We systematically organize the latest patent information in the DMS field, research and explain the “technology issues” and “technology application methods” faced by 36 (*1) major companies in the automotive industry, etc., and provide tagged patent data.
This is a useful resource for engineers and planners to collect information on “technological issues” and “application methods,” to understand issues and to create new ideas for their own technological development, etc.

In fact, a survey and analysis of patent data from 172 countries around the world revealed a marked trend toward an increase in the number of DMS-related patents.
The trend of global progress in technological development was evident.
Here are some recent developments in technological issues and how technology is being applied.

For example,
– Toyota and GEELY are moving to address the issue of false eye detection. For example, the problem of false detection of drivers wearing eyeglasses and the problem of light/dark differences near tunnel entrances.
– General Motors and China FAW are focusing on the issue of excessive warning sounds and displays, which are burdensome to drivers and affect safety.
– Mercedes-Benz and MAZDA are focusing on eye movement saccades to accurately identify signs of distraction and nodding off.
– Panasonic and HYUNDAI are moving to apply AI technology to sleepiness estimation.

Extracting such technological issues and methods of applying technology from patent information will be categorized and investigated in the four fields of “camera,” “biometric sensor,” “AI diagnostic technology,” and “vehicle control including warning,” and will be explained in the materials.
The contents are useful for gathering information on the latest technological issues and methods of technology application.
It is a useful resource for engineers and planners to gain an understanding of key technical issues and new ideas on how to use applied technology based on the expertise and field experience required for DMS.
