Summary
This report created by MarkLines focuses on a number of recent technical topics surrounding the automotive industry and is based on patent information from the “Technology Information Distribution Service - swimy” obtained by the Toyota Technical Development Corporation (TTDC). The two business areas of TTDC are in the fields of intellectual property and measurement control solutions. The intellectual property (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.
This report is a survey of technology trends of thermal management systems related to vehicle drive motor cooling based on patent information. The number of patent applications has been on the rise in recent years. Next, a review of the representative patents of each company confirms that each company employs a different configuration for the thermal management cooling circuit hardware. In addition, this report confirms the existence of patents suggesting the contents of the exhibits at the Automotive Engineering Exposition 2022 Nagoya, held from June 29 to July 1, 2022.
