Denso Corporation today announced that it has decided to increase its stake in Renesas Electronics Corporation to accelerate the development of various in-vehicle systems including automated driving systems that are becoming more advanced, complicated, and larger in scale than ever before. Renesas has cutting-edge technologies for semiconductors that serve as the key devices in such systems.

To meet the needs of complicated vehicle control, the functionality of in-vehicle microcontrollers has been increasing. This is causing their design and manufacturing processes to be more difficult. Manufacturers are expected to accelerate the development of new semiconductors for diversely advanced systems for automated driving, electrification, IoT, and connected driving through a combination of communication and AI-related technologies.

By leveraging its knowledge of in-vehicle products acquired through many years of operation, and in order to develop competitive vehicle control systems in new fields such as automated driving, Denso considers it essential to further enhance collaboration with semiconductor manufacturers that have profound experience and expertise.

Renesas is a leading supplier of in-vehicle microcontroller and has Renesas autonomy to offer complicated and advanced technologies as an open platform. Its basic growth strategy is to offer comprehensive solutions from cloud services that contribute to automated driving, sensing, and vehicle control. Denso says it will continue the joint development with Renesas and accelerate the development of technologies to create competitive in-vehicle systems.
