Exploring key technology networks of telematics using patent analysis

Abstract

This study used telematics patents as the basis for analysis, constructing a technological network for telematics patents. The results revealed that the key telematics technologies are mainly focused on vehicle operation, traffic control systems, wireless networks, and road transport; the key technologies were not focused on specific technologies fields, but possessed the characteristics of multiple technological areas. In addition, the development of services or facilities specially adapted for wireless communication networks has been the most vigorous technological development. The trend indicates that the development of wireless network technology for telematics remains the focus; examples include the compatibility problem of cars and vehicles, 5G development, and even the standardisation and regulatory bodies, certification, and approval processes in the field of wireless communications. The patent technology network model constructed in this study can serve as a reference for the government to promote emerging technologies and allocate research and development resources.
